Hi Peter. It's been almost 30 years ago, but I did a lot of work on ducted fans. In those days I didn't have electrics so I was using weedeater motors. 6 of them. Talk about loud. I removed the governors and was able to spin them to 10 grand. Between the noise and flying debris the neighbors forced me to stop and my test rig was just too big and complex to move around easily. I actually set it up in three different places but complaints killed the project. At any rate, my experience determined that a 5 bladed fan with straight paddle blades set up so that the fans were about 1/8 inch apart ( fans to middle engines front and rear ) produced the highest thrust. I was able to get almost 150 lbs with a 24 inch diameter fan. Yes, tip clearance was critical. I wound up using a three axis mount ( like a y ) as torsional flex in the mount would allow the blades to impact each other. The legs were airfoil shaped and pitched to shape the airflow in and out to minimize spiraling flow and torque effect. The intersection of the legs wiht the duct were about 4:1 width to the inner points at the nacelles. These intersections were CRITICAL. Any disruption of flow was seriously magnified downstream. They had to meet at a near perfect 90 degrees and radii at the intersections worked best around 3/32 in. I was experimenting with variable pitch blades to reduce spooling times when I quit doing research due to neighbors. This is where I really had problems with blade contact leading to some rather spectacular explosions and disintegrations. I had lots of vhs video tape of these experiments but a house fire destroyed them. I've often wished I could start back and have specifically thought that modern high output electrics were the key. Unfortunately I am now retired and disabled so I haven't got the funds or the stamina to persue this research any more. If you would like to pick my brain and check into my work let me know. I'd get a big kick out of working with a bright young person such as you.
I finally made it in to a Peter Sripol video!!!! I was the orange blob ahead of his first launch taking pictures. Peter, my favorite part that was not on video was seeing how excited you were to find the broken spars. That was great. Awesome machine you made, I wanna fly it next time. Let me know when were are flying in Nati. You rock brother!
I love you peter. Thanks for actually building these things most of us just talk about! I love that youre getting into paramotoring. Such an amazing sport.

i believe the front motors by taking on the work of pre accelerating the air made em more efficient thus the 20% extra battery left in the rear which isn't bad for saftey margin as if the front motors cut out you still have half thrust to maintain half the airspeed you had maybe just enough to maneuver a landing but then you'd glide down anyway with the parasail just a bit faster the more weight you carry and smaller wings
Awesome job! Those motors were huge. I have to imagine the sound and being so close to them gave people a jolt. Your duct design looked pretty good, but you could definitely squeeze out more efficiency. I like seeing how you push things to such extents. You really bring life to what others would consider grand ideas.
i feel like they would have adjusted the rod behind his neck and should have kept the parachut stings abouve those motors so that they dont have to stretch their hands always for lift up
BRO!! You have no idea how exciting it is for me to see you enter my world of squishy-wings and butt-fans! If you're ever in my neck of the sand, let me know! I have some EPIC places to fly!
“Props” to you for the R and D on this. The easy comment would be just buy a moster but it’s guys like you that will invent a better bird. Nice job and nice BGD wing
Here's an idea. As a paraglider pilot, I always dreamed of something to gain initial altitude before moving onto soaring flight. There's towing rigs and such. But what about a big quadcopter that is worn as a backpack, then jettisoned once you are up to altitude, and it flies itself back to its home/charging station. Not the worst idea, right?
Jail time.. you’d really really have to piss some people off for jail time I’d think. Flying low and around private property you’d be hard pressed for anyone to even find out
@@feelincrispy7053 the US had more military and prisons that anywhere else in the world. The US absolutely has the most oppressive airspace rules in rules in world.
Nice, this gave me some ideas: 1. To get a "large pizza" while still using small motors, perhaps you could run them in series instead of in parallel, so to speak. You could either have multiple motors turning a separate single propeller shaft via gears or belts, or you could have the motors share a single shaft connected to the propeller. 2. To eliminate the torque roll from a single large propeller disc perhaps without the inefficiencies of typical counter-rotating propellers, you could have the stator and rotor of a single motor each connected to a propeller, so that there would be no net torque roll. Just some ideas I had while watching your cool video, Peter!
I'm assuming you used lipo batteries yes? Here's a story: When I was a kid parents didn't give me any lunch money, so I had to get some myself, I was making custom li-on battery packs to replace existing li-po for drones/planes etc. Review from one customer: Before I had to land and swap the lipos to keep flying, now I chuck that li-ion battery in and it flies, it flies, it flies... then my legs start to hurt and I just need to land the plane, not because battery goes low, but because my legs can't keep me up anymore... So you want to get most dense li-on cells and get someone to weld up a battery pack for you, it will give you at least 3x the flight time compared to lipo with the same mass. Just make sure its well built, if poorly constructed it can be more dangerous than a lipo, it will disintegrate upon impact, short connections and lit on fire.
I love that after all these years you still use music from TechnoAXE, i found out about his stuff randomly forever ago and that ended up recommending your videos to me!
It's actually better if the back propellers have 20% more battery than the front propellers, because it makes it more likely for you to safely land when the batteries of the front propellers are completely empty. You won't get much more flight time, but just enough for an emergency landing to hopefully not end bad.
cool thing about having a wing is you don't need any thrust for it to work. As long as your above suitable ground for landing you don't need any thrust.
@@Siphonife So you mean the paramotor should have wings on the side of the propeller/propellers, or above and/or below the propellers? I could see a cross-shaped or T-shaped wing being added to the top and back of the current contraption, to be able to steer and glide. For only gliding, a wider (front-to-back) wing but not so long (left-to-right) wing would be useful, with steering in the back of the wing for pitch and roll, and rotating half the width (not thickness) of the wing left-right for the yaw. All of this would add more weight and complexity, but he made a plane, so he could probably turn a paramotor into something resembling a short/tiny plane.
@@nikkiofthevalley Oh, then it all makes a lot more sense. Thank you! While you don't need thrust for it to work, you do need velocity, otherwise you would simply stall. *Edit:* And fall. Without velocity relative to the air around you, you would stall and fall.
When strapping into your harness, you must always fasten your leg loops first, before your chest strap. Incase a gust makes you launch unexpectedly! People have lost their lives because of this. It’s more important hill launching, but needs to be done always. Safe flying
As an ex paragliding instructor, absolutely..... plus helmet should be on before getting in the harness. The amount of people picked up and dumped on their heads, even on flat ground, is considerable. Seen some pretty nasty injuries from it.
You could do a up+down version of this. + Slimmer + Less heavy structure required + Lighter + Stronger - needs foam flow combiners - needs front covers - small decrease in airflow
Vertical arrangements would require air to flow around the pilot with sharp changes in airflow directions reducing thrust. Ducts are very sensitive to inflow turbulence that mesh guards in front of the ducts would induce
@@michaelmagill189 yes that's true and it's a problem to solve or workaround. Propellers and ducts can develop quite a lot of thrust like this though. Flow combiners could be used behind the pilot, to fill the low pressure area and guide the air smoother towards the duct. With flow combiner I just mean a Chunk of reinforced foam that tapers from the pilot's rough surface area towards the space in between ducts and a bit of funneling structure towards the ducts. It's too difficult for me to describe it with words and adding to that i'm German
@@WetDoggo low speed ducts want to be as short as possible. A longer duct pushes the operation toward higher speeds. Fine for airplanes but not parasails. These things want massive volumetric flow at relatively low velocity. The big advantage of coaxial fans are higher thrust from a smaller unit and elimination of torque. They suck up a lot of power for what they produce and to get any real efficiency the fans need to turn at very high speeds which creates spooling lag and slow throttle response. Just like the early jet engines just with no hot section to blow out. See my direct post on this vlog for more details on my experiments. Always fascinated by this subject.
So frickin rad, man! Great job! - Have you ever considered using a large helium filled blimp, lifting body or a balloon, instead of the parafoil? Adding a 360° swivel-mount above the pilot and below the balloon would allow for some precise control over the aircraft. - That would be an awesome build to watch. 👍
On this historic day, we remember the Wright Brothers: Orville and Redenbacher, whose dreams and visions inspired generations. And now, again, one man's vision ushers in a new era of aerial travel, proving the power of imagination and intellect. The magic... of flight!
Your inventions are always so spectacularly awesome! I've been waiting on a ducted electric fan paramotor for ever as it seems like a great use case for ducting. So awesome that you are the one to make it happen. Wonder if you could solve axial tilt with pid loop similar to drone controller.
get your battery powered flight machines Ram Air Turbines! it'll make your battery powered ultralight and paramotor powered for longer. might be an interesting challenge for the paramotor but the ultralights i bet it can make a noticeable difference 'relatively' easily.
Hey Peter, my suggestion for reaching 2 million subs you should build a giant rc aircraft carrier , with working lauch catapults and arrestor wires and elevators .
I'm constantly shocked by the innovation and skill this guy displays. Also, the ballsy-ness of trying out the designs himself. I wish I had even 1/2 this on tap! I don't even understand the math!

@@dakotaknoble2556 heh, accidental warcrime pissing off the geniva convention dropping 5 or more gallons of accidental burning fule/ napalm from the air XD
@@Leadvest - too many to wonder about - ie. at least 5x the weight (allowing for weight and efficiency comparison between ICE and electric motors)Li-Ion (etc) Batteries
Sir , maybe you make it VTOL(vertical takeoff and landing) by makeing the propeller shaft stand on a servo that makes it go vertical or horizantal for VTOL CAPABLITIES
You should add flexible solar panels to the ducts and you might extend your flight time some. We did this on my buddie's electric boat and it really helps. 8)
Awesome project! Would it be better to have both motors in the same duct rotating in the same direction? And have the two ducts counter-rotating wrt each other? You’d probably need to reinforce the structure to deal with the extra torque, but might bet much cleaner airflow through the ducts (and quieter too) 🤓
Now you're getting close to my favorite hobby, Hovercrafts. If you're looking for a project idea, electric Hovercrafts are in super infancy and it would be awesome to see your take on it.
Don't see you doing it. It's always easier from the armchair. Ever watched doc's on development of jet engines ? Crude indeed. Bet those guys were engineers too
Those ropes rubbing against that worries me a lot. Peter is definitely smart enough to know a flaw. I've watched too many videos of climbers losing their lives, or getting seriously injuries because of minor flaws in their rope.
Fucking finally, thank you for explaining that a ducted fan is all about really tight clearance. So many videos on here with "ducted fans" are just shrouded fans with no efficiency gain, just protection for/from the blades (which is a good thing, it just ain't a ducted fan).
would love to see a single prop version with variable transmission like they use in scooters. This way you could have a smaller motor running a bigger prop an have a longer flight time. this way you only adjust how fast it should tension with the rollers. So take a normal fuel powered setup, replace the engine with a smaller electric engine and a variable transmission and see how it goes-
You could use the fan blades to cut away at the foam like some cursed drill press to ensure a perfect fit with tiny clearances. F1 cars do this with the floor of the car using magnesium to ensure they were as close to the ground as possible by scraping away any material that touched, leaving only a perfectly shaped floor
You mentioned the efficiency loss due to the coaxial fan arrangement... It's also a major contributor to the NOISE. I understand flying is the priority here, but the dirty, turbulent air hitting the second prop is a major contributor. You're also getting a blade pass tone when the blade crosses the motor support. In HVAC we address this by minimizing the cross section of the motor support in the direction of airflow, and use spiral swept blades or swept motor supports to "flatten the curve" of the noise generated by the blade passing through that airflow disturbance.
Hi Peter. It's been almost 30 years ago, but I did a lot of work on ducted fans. In those days I didn't have electrics so I was using weedeater motors. 6 of them. Talk about loud.

Reminds us at the days when every flying thing was built inside a garage!
Dude your hand and all your fingers. It had more power then I thought it would. Saftey my friend we love your stuff.
You should make a massive drone lol
The real Gyro Gearloose!! Very nice!!
Awesome project!
Would it be better to have both motors in the same duct rotating in the same direction? And have the two ducts counter-rotating wrt each other?
You’d probably need to reinforce the structure to deal with the extra torque, but might bet much cleaner airflow through the ducts (and quieter too) 🤓
It's better for the rotors within a single duct to rotate in opposite directions to each other- that way you can maximize thrust.
Well done sir. You are the kind of person (adventurer) that I hope my children grow up into.
I love the new toy 😍 Can’t wait for the next adventure dude! See you soon!
I've said before and I'll say it again, this man is a national treasure. Oh, and a genius too!
You have hit 2Millionen subs! Congrats 😃🥳
You've created a human salad shredder.
I swear, Peter is either gonna become a super *hero* or super *villain* with all the flying gadgets he's made.
As a Builder of small A/C ... you've got great skills and an even better Workshop!
This is super cool. Top tier content.
The vulture suit is getting a nice start I see.
Now you're getting close to my favorite hobby, Hovercrafts. If you're looking for a project idea, electric Hovercrafts are in super infancy and it would be awesome to see your take on it.
Have fun, Don't Die I saw that sticker !!! she is awesome. (the foraging lady who always says that)
When the world needed him most, he returned.
Lol. Definitely an engineer. "These bolts sticking out won't hang anything..." He does amaze me with his stuff though.
Don't see you doing it. It's always easier from the armchair. Ever watched doc's on development of jet engines ? Crude indeed. Bet those guys were engineers too
Peter you absolute maniac. Keep being awesome.
I watch peter's videos because many of his ideas are very interesting. Of course, his smile is very charming.
A cool way to cruse the skies 👍🏻
Yes, a follow up!
“Oh, where are my safety glasses?” I applaud your concerns with safety, but feel you might be missing the bigger picture 🤣😂
cool and awesome
Those ropes rubbing against that worries me a lot. Peter is definitely smart enough to know a flaw.
I've watched too many videos of climbers losing their lives, or getting seriously injuries because of minor flaws in their rope.
My man went from building drones to BECOMING the drone
Crazy how quick you have evolved this
The shape of the duct matters ALLOT. I watched where a guy 3d printed up a ton of different ducts some where 10x more efficient than others
Nice. Fun to see all my paramotor friends flying in one of you vids
Fucking finally, thank you for explaining that a ducted fan is all about really tight clearance. So many videos on here with "ducted fans" are just shrouded fans with no efficiency gain, just protection for/from the blades (which is a good thing, it just ain't a ducted fan).
would love to see a single prop version with variable transmission like they use in scooters. This way you could have a smaller motor running a bigger prop an have a longer flight time. this way you only adjust how fast it should tension with the rollers. So take a normal fuel powered setup, replace the engine with a smaller electric engine and a variable transmission and see how it goes-
The differences in electric and internal combustion power delivery deletes the requirement for a variable transmission in nearly all use cases.
You could use the fan blades to cut away at the foam like some cursed drill press to ensure a perfect fit with tiny clearances. F1 cars do this with the floor of the car using magnesium to ensure they were as close to the ground as possible by scraping away any material that touched, leaving only a perfectly shaped floor
Dog looks like, 'This is the one that's going to cause me to stop getting fed'.
You mentioned the efficiency loss due to the coaxial fan arrangement... It's also a major contributor to the NOISE. I understand flying is the priority here, but the dirty, turbulent air hitting the second prop is a major contributor. You're also getting a blade pass tone when the blade crosses the motor support. In HVAC we address this by minimizing the cross section of the motor support in the direction of airflow, and use spiral swept blades or swept motor supports to "flatten the curve" of the noise generated by the blade passing through that airflow disturbance.
Fantastico!!!!!!👏👏👏👏👏👏👏👏 Un prodigio!!!!!! Siete de veri inventori !!!!!! Dei prodigi 👍👍👍👏
