@davidwoodward6112 Engine manufacturers who have delivered reliable products for nearly a century. Look at Rotax. For all of the high technology and new design it still doesn’t have any better power to weight than a Continental O-200 that’s based on a nearly 90 year old design! And the Rotax has four failure modes the Continental doesn’t (dog clutch, gear box, coolant leak, additional throttle linkage).
@@calvinnickel9995 The Rotax 916iS now produces 160 HP, 141 HP continuously, right up to 18,000 feet. The Rotax 912 series engines do have more clockwork to break, however, the gearbox is very reliable, there are no magnetos to maintain or fail and the fuel injected Rotax engines have no carburettor to maintain or to ice up. Carburettor icing of the O-200 has caused thousands of engine failures and hundreds of fatalities. Carburettors should never be installed on an aircraft engine. The DeltaHawk engine is much better than both. No crankcase halves to fret. No separate cylinders to fail. No camshaft, lifters, valves or guides to fail. No ignition to fail. No carburettors to ice up. It is a great shame that the DeltaHawk was not certified 25 or 30 years ago and offered at a price competitive with the Lycoming IO360 and IO390 that it replaces with V8 versions to replace the Continental IO520 and IO550 and Lycoming IO540 engines. Continental have, of course, moved over to diesel with the CD300, however, that is a standard Mercedes automobile engine with reduction drive and accessories added by Continental. It looks like the Continental CD300 is much quieter, smoother, more efficient and more reliable than the IO520 but there are very few new certified piston engine aircraft being manufactured today and developing an STC for legacy aircraft takes a lot of time and money. Cirrus favours Continental and Lycoming air cooled gasoline engines and Diamond install water cooled Continental diesel engines.
This is exactly right. "Airplanes are not allowed to crash, and childrens' toys must be safe". Tort reform in 1986 got Cessna to restart its general aviation business, but its still far too expensive. A decent panel with modern avionics can cost 100s of thousands of dollars. Engines and maintenance are expensive, tedious, and slow to adopt new better tech. Thats not because the tech in general aviation is necessarily otherworldly, it's because of the risk portfolio (lawsuits) any certified aviation supply chain has to mitigate.
@@K-Benz Here in Austria, we have had planes with diesel engines for years, and also the much more compact and efficient geared engines from Rotax. They are sold well in Europe, but in the USA they prefer the outdated engines from Lycoming and Continental. Just have a look at Diamond Aircraft.
Fluff piece. Don't like the voice. Lack of details makes the whole thing suspicious. WHAT is so great about this engine? I hate click-bait. RUclips should have a Click-Bait rating.
The long and short is that it's a piston engine that can run on kerosene-based jet fuel instead of general aviation fuel, which is basically a grade of leaded gasoline. That makes it cheaper and cleaner to operate, and allows more kinds of small aircraft to use a widely-available industry standard grade of fuel.
The engine might be fantastic. It might run on multiple fuel types, including water. It might produce emissions that I can breathe, and improve my health. it certainly looks pretty, and nicely made. Having watched the video, I know less about the engine than I did before I watched it. I think the teaser for the Emporer's new clothes had more hard facts than this! It would be great if everything that is hinted at proves to be true... fingers crossed.
from what I can see in the video - It's liquid cooled turbo diesel with a planetary prop gear reduction. Mercedes made the same set up for the diamond diesel but it was an inline diesel -not a V.
2 stroke turbo diesel inverted V-4, 40% more efficient (per gallon or lb of heavier jet fuel?). It's been in development for 30 years so it's about time, and maybe finally zero lead gasoline is accelerating interest. The Delta hawk should be very efficient and low maintenance, but NOx might be a problem, but better than lead pollution.
@@glike2 just to delineate. Diesel is 40% more efficient(joules of energy) than gas if you can tap those joules/calories. However, 2 stroke is less efficient than 4 stroke. With the turbo hopefully they can remediate some of the 2 stroke inefficiency.
@@ColinMill1 Detroit Diesels for boats due the same since the 1950s-60s. However, they weigh in the thousands of pounds. The difficult parts is the get the weight down on something that has compression ignition at about 22 to 1 instead of 8 to1 or lower like gas motors. All while incorporating redundancy or reliability required by the FAA for certification. Then let me ad that when mounted, the engine has to be aerodynamic. These are some of the many difficult issues with a simpler technology. Stop thinking inside a small box like most insipid American, that’s why we get the elected incompetent officials we have
@@ColinMill1 592HP at 1653 lbs is way too far from the HP/LB requirement. This engine at 357 is going to be certified soon for higher HP likely 230hp and beyond. Previous attempts are a swing and a miss. I has to say it once I have to say it a thousand times. Weight = difficult, weight = less then simple, weight = less than easy, weight = not done before, weight = new technical applications. Just like Carville, it’s the weight stupid
I didn't learn anything from the video so I went to their website. It is a 4 cylinder diesel, turbocharged, non geared with glow plugs, 180 to 235 HP. I'm not sure why it took so long to develop, (possibly certification). The fact that it uses jet fuel is a big plus since Avgas is more expensive and more difficult to find in many countries. My favorite cool engine was the turbine engine for 1963 Chrysler two door coupe. It obviously had to be geared but could run on non leaded gasoline, jet fuel and tequila.
Same experience here. The video was a synopsis for idiots. I do believe the future of small general aviation aircraft is with diesel engines. If I were to try to enter the aircraft engine market, it would be with a 4 or 6 cylinder NON-GEARED turbo diesel with intercooling. Perhaps the homebuilt market could be a good place to start and gain experience.
I wish them the best of luck, but the history of new aircraft engines is populated with dozens of great engines that failed, not because they weren’t wonderful but because the industry and the government agencies that regulates it are impossible to break into.
I believe it's a diesel engine. Not sure why that wasn't pointed out other than reporter didn't take the time to ask or he doesn't know the difference.
@@MBCGRS I believe you. Here's from DeltaHawk website: The engine's base technology is Compression Ignition (also known as Diesel) that is known for durability, high efficiency, and incredible torque.
If it's multifuel then it's either turbine, diesel, or alien technology. Would have been nice if they had said which. That's not divulging trade secrets.
Really low compression can also be multifuel. The Ford Model T had a 4:1 compression ratio and could run on gasoline, kerosene, wood gas, just about anything. The problem is its efficiency was terrible.. 20hp out of 2.9 litres.
On the contrary, aircraft engines are incredibly simple. This thing, with its diesel injection and its high compression, might be too complicated, or too heavy, or both, to be useful.
DeltaHawk diesels have been in development for many years now; the best part about them besides the efficiency is that they're liquid-cooled unlike legacy Lycoming and Continental engines.
My daughter has worked at Delta Hawk for the past 5 years...She started as an intern in highschool and worked her way up through most of the departments. She has help build this engine, hands on... Delta Hawk is an AMAZING company and takes care of their employees!!!
She made parts and stuff like that .. she didn't create the blue print... Delta Hawk already did that before she started... But she crossed trained in almost every department if not all departments... She is extremely smart!!!
DeltaHawk have been pushing diesel aero engines for many years, for me, the biggest plus would be getting rid of AVGAS it seems incredible that light aviation is still burning Gas with Lead tetraethyl in!

At 0:20 seconds the guy says that airplane engines are incredibly complicated, however most airplane engines that would be replaced by this Deltahawk engines, are actually extremely simple machines, basically a large VW Beetle engine.
I believe Vulcanair will be installing them on their twins as reported in an article on July 23. The engines have been extensively tested in test bed aircraft and I believe they were FAA Certified in May 2023. Regards from South Africa
So, given that the video says nothing I think we can see from the pictures that it is a forced induction 2-stroke diesel. They have been around a while now - at least 80 years.
It's essentially a paper weight if you can't get it STC'ed into existing certified aircraft. The only market for brand new certified aircraft of this category is flight schools and even then we are talking about sales numbers in the single digits per year.

@@hedonismbot1508 it’s going to be a long time for that because 1 gal of avgas is 36kw. A long range Tesla is 77kw. Maybe 2 hours of flight but that’s not counting the weight of the batteries. Planes require way too much power to be practical for electric power. Petroleum is a great carrier of power. Someday we’ll have super conduction motors higher efficiency solar, and maybe something not invented yet but for now and for a very long time planes will need gas.
@@CliffordStaley I was referring to developing an engine that burns something without lead. Some homebuilt planes can take automotive gas, for example.
Many piston aircraft can leagaly use unleaded fuel. Auto gas was FAA approved in 1982, now there are several specific aviation gasolines approved. The issue is the political will to make them available at airports. I consider insurance issues as part of the political problems. Airports and many aircraft owners insist that it is only possible to carry one type of a gas that all can use and that is 100 low lead, how many grades of gas is at the local gas station? That is what I mean by the politics being the issue it's not really a technical problem. @@hedonismbot1508
Lycoming and Continental aircraft engines use pre-war technology, from the 1930s, air cooled, magneto ignition, manual in-cockpit adjustment of carburettor.
“Most of these planes can only use a certain type, of expensive fuel only found in certain parts of the world” You mean the CHEAPER 100ll found at practically EVERY airport in the developed world? What a joke
I believe that a clean sheet design engine can doo all that's claimed here - but how can it be done without electronics? Switching between fuel types and maintaining top efficiency is hard and I assumed needs some clever electronics.
Piston aero engines are not complicated. They're simple and reliable, naturally aspirated and air cooled. Engines from the 40s are routinely in the air. The engine from this video is water cooled, super charged AND turbo charged. It uses alternators instead of magnetos. It doesn't have a valve train (uses ports) and no plugs (it's a diesel) so no variable timing apparently. Rotax 915 offers same hp (130) for half the weight.
Great idea but a few years behind in its thinking. Rotax have been certified for mogas ever since their introduction. In fact Rotax recommend only using avgas if you have to. In Britain that gives a large saving on fuel costs when Avgas is over £2 a litre in many places but mogas is about £1.5 at most. Added to which the Rotax burns about 4gallons an hour in the cruise against 8-10 in a Lycoming or Continental of the same power
If you look at the specs, the fuel burn is where most engines are today. The sad part for me is 235hp is the highest rated engine they produce. I would love to see 300hp or more at these burns.
thank you for not including one piece of actual information about the engine at all. not one fact or figure or anything - efficiency? fuel burn? nothing to go on, means we're not interested.
Can the average pilot afford this? What I’d love: * brand new avionics * 300 knots * less than $90K to run all in * $300K to buy Now what I just described can only be obtained as either a turboprop or a jet and even used, it’s a struggle these days to find anything below a million. Just 6 years ago, you could easily find that for $600K. I don’t care if some great new gas sipping engine comes out if it’s doing 135 knots and costs $3 million. I’d rather buy a used TBM 750, which you can get for about a million.
2:15 advertisement with zero discription of the engine. It appears to have a turbo and be liquid cooled. How long will it run over the rocky mountains when the coolant leaks out?
For at least 5 years after certification, you have to sell your engine to the manufacturers, plus you have to start paying off the large development costs in the last 2 decades. If you make it through those , then you can talk about your engine as the future of flying. Your future will be largely determine by the cost of your engines. Some examples of clones being made are Rotax, PT-6, Wabasto heaters and Snap On flank drives. You have under 1/4 century for patents. The only way to get around it is at the patent expire time, you find something wrong with your product, and start pushing a new product. So if you cannot make money from it, no one else can, examples are R12, R134a and now R1234. for your AC. You are the second such engine on the market, there is also one called the WAM100 that were still born , starved of funds in England.
TMJ4, you people need to read the room. The targeted audience for this story are aviation enthusiasts. The general public could have got what they needed to know in 30 sec while aviationist can be satisfied in the next 50 sec of info.
I'm also building an RV10 and these companies still don't understand how this works. They need to sell the first 500-1,000 engines at a deeeep discount over an equivalent Lycoming or Continental to owners who are willing to help them prove out the design. They will never beat the incumbent at a higher price point when existing offerings have millions of proof hours on them and cost less. I hope Delta Hawk has enough cash in reserves to sell these at a price that is compelling enough for owners/builders to take a risk flying behind a new product, and take an even bigger risk that Delta Hawk survives and is around long enough to provide service and parts 10 years from now. The equivalent IO-360 costs between $40-50k. Once they get past market acceptance and clear proof these things are reliable and serviceable, only then can they maybe ask for the same price point as similar 180hp engines. They can accept this reality or die like the majority of aviation engine start-ups.
You elaborated more than I wanted to. This is exactly the problem ...braking the market. It takes several years with a below completive price, it takes decades with completive prices. Now it will take for ever with over priced engine.
An injection system from the 1950th should be efficient? Very interesting! I would wish an aircraft engine which is as efficient an reliable as every single car engine.
This engine as the reporter said has been decades in development. That is NOT and exaggeration. It is a boosted 2 stroke diesel, and it supposedly burns clean with no electronics.....? The 6-71 Detroit Diesel also had no electronics and they do NOT burn clean as I've had one. Perhaps the jetfuel helps but after nearly 40 years of working out the bugs, I still am not convinced. Perhaps it's time is here, but I doubt it. I do hope Im wrong however. Even if it now works great, it will most likely be priced out of reach of most people.
The "Why?" this is a big deal is missing. It's the fuel it burns is the story! Jet-A or Diesel, not low lead gasoline which is a very small market compared to the diesel/jet-A fuel types.
1 - Aircraft engines are simple. As simple as possible. 2 - I'm trying to find a way you could brag about your product while being more vague. 3 - From what I can see in the video this is an inverted V - 4 cyl - liquid cooled , turbo charged diesel with a planetary gear reduction to the propeller. What they're trying to do is protect their product so nobody can beat them to a type cert and production.
its a direct drive 2-stroke mechanically-injected turbocharged diesel with a supercharger/blower for start up, like most 2-stroke diesels have. the belt driven blower can be seen at 2:02 min. the ring gear shown is for the starter. this is an amazing engine. its service life TBO is 3000 hours, not 2000 hours. this combined with 40% less fuel burn and a lower cost per gallon fuel, make the engine much cheaper to own in the long run. this is indeed the future of GA.
Diesel fuel is cheaper and much less volatile than av gas. With this diesel 2 stroke, having much less moving parts than a gas engine is always better. I remember back 15 or 20 years ago when these diesel engines were being billed as being much lighter than their gas counterpart engines. Comparing the weight of this diesel to that to the other 180 hp gas engines out there like the O-360s, the 335 lb weight is considerable. With the 235 hp versions compared to the 470 and 540 engines, the weight is mush better. But to me, the $110k starting price for the 180 hp versions is a bit steep. That's nearly twice the price of a factory new IO-360 and $35k-$49k more than a factory new IO-470/540.
The main driver of aviation costs is lawyers.
And engine manufacturers with FAA certificated monopolies.

Airports and many aircraft owners insist that it is only possible to carry one type of a gas that all can use and that is 100 low lead, how many grades of gas is at the local gas station? That is what I mean by the politics being the issue it's not really a technical problem.

It looks good! I'd like to see a test stand run-up.
Proud of you.❤
GOOD LUCK!
Good for DeltaHawk. They've worked for it, smartly, and now it's going to pay off. More people, more firms need to be like this in North America.
The problem with diesel engines is heat and weight. The air cooled gas spark magneto engine is the simplest and most reliable to date.
Interesting … and gorgeous that G222 in the background
Lycoming and Continental aircraft engines use pre-war technology, from the 1930s, air cooled, magneto ignition, manual in-cockpit adjustment of carburettor.
The main reason that airplanes still use ancient technology engines is because of government (FAA) ancient certification requirements!
“Most of these planes can only use a certain type, of expensive fuel only found in certain parts of the world”
You mean the CHEAPER 100ll found at practically EVERY airport in the developed world? What a joke
Europe is outlawing low lead and my understanding is it’s difficult ,to find in Africa. Don’t know about parts of Asia and South America.
Low lead is on the way out and, where I work is more expensive than avtur
@@Bakes-z4c You likely work at a larger airport with a lot of jet traffic, that’s the only place I’ve seen jet A cheaper
I believe that a clean sheet design engine can doo all that's claimed here - but how can it be done without electronics? Switching between fuel types and maintaining top efficiency is hard and I assumed needs some clever electronics.
Or no electronics
Congratulations Delta Hawk… 👍♾️🇺🇸
Piston aero engines are not complicated. They're simple and reliable, naturally aspirated and air cooled. Engines from the 40s are routinely in the air. The engine from this video is water cooled, super charged AND turbo charged. It uses alternators instead of magnetos. It doesn't have a valve train (uses ports) and no plugs (it's a diesel) so no variable timing apparently. Rotax 915 offers same hp (130) for half the weight.
You see that building at 2:07. That mesh is faraday cage material. No one is stealing those trade secrets.
Your shirt looks RIDICULOUS!
ALL engines are the Future of Flying. Because without them, nothing will fly.
I like homebuilts anyway and any lite weight strong type is where Im goin with my designs.
I even imagine twins or 4 of these on a homebuilt
Great idea but a few years behind in its thinking. Rotax have been certified for mogas ever since their introduction. In fact Rotax recommend only using avgas if you have to. In Britain that gives a large saving on fuel costs when Avgas is over £2 a litre in many places but mogas is about £1.5 at most. Added to which the Rotax burns about 4gallons an hour in the cruise against 8-10 in a Lycoming or Continental of the same power
If you look at the specs, the fuel burn is where most engines are today. The sad part for me is 235hp is the highest rated engine they produce. I would love to see 300hp or more at these burns.
thank you for not including one piece of actual information about the engine at all. not one fact or figure or anything - efficiency? fuel burn? nothing to go on, means we're not interested.
Can the average pilot afford this? What I’d love:
* brand new avionics
* 300 knots
* less than $90K to run all in
* $300K to buy
Now what I just described can only be obtained as either a turboprop or a jet and even used, it’s a struggle these days to find anything below a million. Just 6 years ago, you could easily find that for $600K. I don’t care if some great new gas sipping engine comes out if it’s doing 135 knots and costs $3 million. I’d rather buy a used TBM 750, which you can get for about a million.
I love the engines and wanted two but, their many years of development has caused a price higher than I can afford.
2:15 advertisement with zero discription of the engine. It appears to have a turbo and be liquid cooled. How long will it run over the rocky mountains when the coolant leaks out?
Diesels can run longer than gas motors without coolant. And no, the turbo is not liquid cooled just the engine.
Heavy on claims but no information on how/why it’s so great.
Beautiful ♥️
I'm going to contact these people before I judge them too harshly.
Great sales pitch with no stats of facts. I feel like I just watched a Kamal Harris speech.
nice, this engine can be upgraded with a turbo intercooler also for more power....
First impression on placement of parts - Oil and fuel filter is incredibly close to the exhaust manifold. Cant be good.
This engine is made by Deltahawk, Just google deltahawk engine. I think the base engine starts at 60k
Aircraft engines tend to be much more simple than modern auto engines.
This the safest engine ever made, because it will never fly. The lawyers have made sure, that only lawyers can afford to fly.
Marinize it! smaller boats use lots of fuel too. this could help.
For at least 5 years after certification, you have to sell your engine to the manufacturers, plus you have to start paying off the large development costs in the last 2 decades. If you make it through those , then you can talk about your engine as the future of flying. Your future will be largely determine by the cost of your engines. Some examples of clones being made are Rotax, PT-6, Wabasto heaters and Snap On flank drives. You have under 1/4 century for patents. The only way to get around it is at the patent expire time, you find something wrong with your product, and start pushing a new product. So if you cannot make money from it, no one else can, examples are R12, R134a and now R1234. for your AC. You are the second such engine on the market, there is also one called the WAM100 that were still born , starved of funds in England.
I looked at Delta Hawk for many years, but they didn't have an STC for any type certified aircraft. Does it have an STC for any aircraft currently?
TMJ4, you people need to read the room. The targeted audience for this story are aviation enthusiasts.
The general public could have got what they needed to know in 30 sec while aviationist can be satisfied in the next 50 sec of info.
I would love to see how it compares with rotax engines.
Inverted V engine? Sweet WWII tech!
I bet you it took them like 8 months to get the engine perfect and 25 years to get it approved by the FAA.
First thing i saw on this engine was internal wrenching bolt heads on the exhaust headers, and i instantly started cussing out an imaginary engineer.
all true.. but Who wants to spend $105.000 for a Firewall Foward kit for a RV10
Their website says starting target price at $110,000 for the 180 hp
So more like $150,000 +. LoL 😂
I can by a lot of 100LL for my Lancair with 105k.
I'm also building an RV10 and these companies still don't understand how this works. They need to sell the first 500-1,000 engines at a deeeep discount over an equivalent Lycoming or Continental to owners who are willing to help them prove out the design. They will never beat the incumbent at a higher price point when existing offerings have millions of proof hours on them and cost less. I hope Delta Hawk has enough cash in reserves to sell these at a price that is compelling enough for owners/builders to take a risk flying behind a new product, and take an even bigger risk that Delta Hawk survives and is around long enough to provide service and parts 10 years from now.
The equivalent IO-360 costs between $40-50k.
Once they get past market acceptance and clear proof these things are reliable and serviceable, only then can they maybe ask for the same price point as similar 180hp engines. They can accept this reality or die like the majority of aviation engine start-ups.
You elaborated more than I wanted to. This is exactly the problem ...braking the market. It takes several years with a below completive price, it takes decades with completive prices. Now it will take for ever with over priced engine.
A new io390 is about 140k
An injection system from the 1950th should be efficient? Very interesting!
I would wish an aircraft engine which is as efficient an reliable as every single car engine.
Hmmm ... turn it right-side up and it can go into small/midsized cars and trucks like the Ford Ranger, Dodge Dakota, etc.
This engine as the reporter said has been decades in development. That is NOT and exaggeration. It is a boosted 2 stroke diesel, and it supposedly burns clean with no electronics.....? The 6-71 Detroit Diesel also had no electronics and they do NOT burn clean as I've had one. Perhaps the jetfuel helps but after nearly 40 years of working out the bugs, I still am not convinced. Perhaps it's time is here, but I doubt it. I do hope Im wrong however. Even if it now works great, it will most likely be priced out of reach of most people.
The "Why?" this is a big deal is missing. It's the fuel it burns is the story! Jet-A or Diesel, not low lead gasoline which is a very small market compared to the diesel/jet-A fuel types.
dawg this is just a normal piston engine, the ww2 planes flew inverted V engines too.
We see the same development in motorbikes. Great, they are shutting down one refinery after the other.
1 - Aircraft engines are simple. As simple as possible.
2 - I'm trying to find a way you could brag about your product while being more vague.
3 - From what I can see in the video this is an inverted V - 4 cyl - liquid cooled , turbo charged diesel with a planetary gear reduction to the propeller.
What they're trying to do is protect their product so nobody can beat them to a type cert and production.
its a direct drive 2-stroke mechanically-injected turbocharged diesel with a supercharger/blower for start up, like most 2-stroke diesels have. the belt driven blower can be seen at 2:02 min. the ring gear shown is for the starter.
this is an amazing engine. its service life TBO is 3000 hours, not 2000 hours. this combined with 40% less fuel burn and a lower cost per gallon fuel, make the engine much cheaper to own in the long run. this is indeed the future of GA.
Diesel fuel is cheaper and much less volatile than av gas. With this diesel 2 stroke, having much less moving parts than a gas engine is always better. I remember back 15 or 20 years ago when these diesel engines were being billed as being much lighter than their gas counterpart engines. Comparing the weight of this diesel to that to the other 180 hp gas engines out there like the O-360s, the 335 lb weight is considerable. With the 235 hp versions compared to the 470 and 540 engines, the weight is mush better. But to me, the $110k starting price for the 180 hp versions is a bit steep. That's nearly twice the price of a factory new IO-360 and $35k-$49k more than a factory new IO-470/540.
Said this 10 years ago….
Another debacle….
The biggest hurdle for this engine is price.
Thank you for calling it an engine.
Well, it work on my Archer?
So. What are the specs ?
In what way is the engine different/similar? Why are the props so short?
Rocking an inverted V configuration like it's 1939.
Where are you located?
How noisy is the engine? Let us know!
The shown vibration of the cone in front view, doesn't give me confidence in the bearing maintenance.
SALUTE!!
Funny how the production is always next year. There are other diesel aircraft engines that are all ready in production.
Tell what the trade mark is to invest in for this company
Is DeltaHawk a private or publicly traded company?
Is it lighter, more powerful, cheaper than a Rotex 912?
I wasn’t aware a Rotax 912 puts out 180 Hp and this engine is going up to 230 ho and beyond. How is the Rotax performing now
about 3 times the power and only 1/3 more weight.
Looks like an inverted V4 - what magical fairy dust it runs on I’m none the wiser…
Hopefully all those job creation projections stay in the USA.
