@@ke4uyp exactly he is by himself and if he blows up…oh well, he died having a blast, get it. No one but him gets hurt. and yeah, when we were kids we all tried to jump the snake River canyon like EK, right? 😉
@@ke4uyp I saw nothing unsafe about this, it was performed in an empty area void of obstacles and cars. He wore safety gear, the seat even had a blast deflector at the rear. It was built relatively well etc. You know as a kid I made way more unsafe things (including one bicycle I threw together in about 2 hours that had an engine using a sawblade right behind me as part of a variable drive speed, and had no safety limits so if you moved the handle too much it would saw through your body), yet I still have all 10 fingers.... I'm also known to put out gasoline fires with more gasoline (it works pretty well, liquid gasoline doesn't catch fire only the fumes, so you can just smother a gasoline fire with more gasoline, I've done that many times. I also laughed my butt off with my wheels on fire (due to a gasoline leak dripping onto the exhaust system) on a very old lawn mower doing 40 mph off-road through a field. All the old farm machinery and heavy equipment is missing its safety covers, and often sticking your hands and arms near spinning saw blades and gears to pry and pull stuff that's stuck in the machine. Yet I still have all 10 fingers. Let me assure you, this guy clearly had a lot of thought into safety just looking at it for 1 second you'd see that, and he did it in an incredibly safe way (even if it caught fire, there was really nothing to even burn where he was at!). If you want to go do something dangerous, go take a shower. Why do I say this? More people die in the US drowning from a shower or bath (very specific I know), compared to deaths by rifles of all kind in the US (of which there are 15 million AR15rifles alone) and consider that most gun deaths are actually suicide, you'd agree that you should be terrified of taking a shower right? Well I try to play it safe and take as few showers as possible (you could ask my mom as a kid), but if we consider all the dumb stuff I've done (it would be a long novel if I typed it), then you'd see maybe we should all just worry a little less, because there are a lot more dangerous things people do like taking showers that you're probably not as worried about...

@@kiwibob223 tbh everytime in the past I saw some1 starting these, he used leaves blowers to make the initial air pressure, so I understand the surprise
As soon as I heard it, I knew what you had fired up. This is same propulsion system as Germany used for their buzz bombs. A pulse combustion engine. I worked for a company that manufactured a product based on this principle. It was studied by a Canadian scientist, Kitchener, during WWII. Kitchener realized that this system produced amazing amounts of heat, and designed boilers based on the principle. They were manufactured by Hydrotherm Corporation in NJ, a division of Penn Central.
That looks like a load of fun but I’d be shitting myself having the gas next to the exhaust due to it looking like it’s hotter than the sun lol great vid
I'm guessing the camera sensor is blowing out the highlights. If it were accurate, according to the kelvin color temperature chart, that would be 5000-6000 degrees celsius (which it can't be because what metal can withstand that heat, right?). So I'm guessing we'd need a camera sensor with more dynamic range to guess the temp - or does anyone know the temp those things get up to?
The camera can lie a bit but the metal color seemed like it was close to the melting point of steel. Its probably the camera lying a bit, but I'd be very worried about getting the thing just explode on my back. But he probably knows better. Yeah It seems its after sunset so the colors seem much more bright than they actually are.

You sir are an inspiration, you show me that I'm not crazy and life is meant to be enjoyed , as a kid who grew up building his own go carts all I can say is....I wanna drive it lol. Keep smiling friend...

@@G6JPG he’s clearly holding his hand out towards the camera it’s obvious he’s holding the camera with a go pro or stick doesn’t take a genius to think figure that out
@@NightmareTrash88 Since the cart (and driver!) do remain well fixed in the image, that does seem likely - but he's skilled at its use: I do _not_ see him "holding his hand out towards the camera" - he frames himself more or less from shoulders up, so you don't see muchof the arm.
@@koolaidman4869 I se what you mean. However, you've got to be fairly familiar with using a selfie stick (or whatever) to realise/recognise that. (I'm not.)
I've very impressed, all the engineering and planning, never seen auto-starting VPJs before, most require a leaf-blower or something I bet that thing goes like a stabbed rat at full throttle
Robert I must say that I’m very impressed with your ambition, technical knowledge, and courage! 🤗 Would you like to take your jet engines to the NEXT LEVEL? My dad, Charles Dahle, was an expert on jet propulsion and he passed on some of his knowledge to me. Your current setup wastes a LOT of energy as you know. You need to turn this wasted energy into thrust. May I suggest that you build what I would call a “steam afterburner.” (Just a name it doesn’t really burn anything) First step is to completely enclose a jet engine with a stainless steel “steam jacket.” Similar to a water jacket on an internal combustion engine, but it houses steam instead. This housing is a simple shell with a “donut” shaped opening at the nozzle. I suggest a 1/4” gap to start with. I would add several rows of fuel injector nozzles. Each row would be activated by an electrical solenoid and of course you are not injecting fuel, but water. Water expands 1600 times when flashed to steam! 😳 When a spray of water hits your engine, that is glowing cherry red, it will flash to steam instantly and give you a tremendous boost in thrust. 😬 There is a LOT of power in steam! Have you ever noticed that a steam locomotive did not have a transmission. It doesn’t need one!!! Anyway, certain precautions HAVE to be made! I suggest using some pressure relief valves found on an air compressor just to be sure that you don’t have a steam explosion. 😬Also your welds have to be flawless! A tiny invisible jet of high pressure steam can penetrate your body before you can say, “I’m a dead man!” 💀 I suggest that you install a piece of armor plate with some sort of high temperature ceramic between your engine and the back of your seat just in case a weld develops a pin hole leak. You should also encourage bystanders not to get too close. High pressure steam is invisible and VERY dangerous! Navy personnel on nuclear submarines use broom handles to check for steam leaks. If the end of the broom handle falls to the floor, they know that they have an invisible steam leak. 😳 By using several rows of injectors activated by solenoids you can increase your speed gradually with each flip of a switch. You don’t want break the land speed record on your first test drive. It probably wouldn’t be that dramatic, but you never know for sure. It pays to be careful! I knew a fellow who owned a Yamaha dealership. He was testing a brand new turbocharged bike. He was cruising along at 80 mph and thought to himself, “This thing runs like crap!” Then he noticed that the choke was on, so he pushed in the choke and did a wheelie stand at 80 mph!😲 Fortunately he was coordinated enough to maintain control and lived to tell the story. Anyway, it always pays to be careful! My inspiration for this idea came from an article about Bruce Crower’s Six-Stroke Engine. He replaced the cooling system on an engine by injecting water directly into the cylinders after the engine reached operating temperature. The water flashed to steam and generated power. He increased the thermal efficiency of the engine and eliminated the weight of a cooling system. This is an AMAZING idea! He predicted that it would almost double the fuel economy of an engine. I suggest you do an Internet search on “Bruce Crower’s Six-Stroke Engine.” Very interesting! I would be very interested to see you try this steam afterburner idea. I have too many projects to try it myself. I think the FUN potential on this idea is pretty high! 🤔 Good luck! Be safe! 🤗 Don’t get killed!
@@jorgeposadas1192 I am a physicist and I like to test ideas out ... It's application to me might not be applicable to propulsion obviously but rather the working principles
I would love to see a cam mounted to view the intake/exhaust side of the propulsion unit, and one forward facing cam on the rollbar. That would free up your hands for a hard pass. The unadulterated joy that we all see on your face is the reason we all build things like this. Well done, sir, may you never end your endeavors for better, stronger, and faster... Cool video, for sure...

I'm not an engineer of any kind, but I was also really surprised at that. I know valveless pulsejets can be a bit tricky to get right, and I'd imagine he has years of trial and error behind that. It also looked like he had a valved pulsejet cart on the back of his truck, so he's definitely been working on some fun projects. Oh, and he probably has hearing loss. Prally worth it tho

that instant start is amazing. I've seen so many people struggling to get the pulsejet started, that I was thinking it'd take 10 minutes to get all 3 jets lit.
How in heck does instant start pulsejet work?
@@erlend1554 it doesn't need airflow as it's an acoustic pulse jet.
Once it starts and as long as there is fuel it's just going to run.
@@erlend1554 I'm pretty sure it involves deep techno magic and the sacrifice of a field full of innocent virgin frogs.
@@kiwibob223 tbh everytime in the past I saw some1 starting these, he used leaves blowers to make the initial air pressure, so I understand the surprise
As soon as I heard it, I knew what you had fired up. This is same propulsion system as Germany used for their buzz bombs. A pulse combustion engine. I worked for a company that manufactured a product based on this principle. It was studied by a Canadian scientist, Kitchener, during WWII. Kitchener realized that this system produced amazing amounts of heat, and designed boilers based on the principle. They were manufactured by Hydrotherm Corporation in NJ, a division of Penn Central.
I just realized the military's "chinese mortar" field water heaters are very VERY loosely based on this design! 🤣
Same here. The distinctive "growl" it makes left no doubt in my mind what he'd just lit off.
How fast You figure that can go?
That looks like a load of fun but I’d be shitting myself having the gas next to the exhaust due to it looking like it’s hotter than the sun lol great vid
I'd prefer to see some sort of heat shield between them!
Ah that heat make propane put out better
My thoughts exactly 🤣
I'm guessing the camera sensor is blowing out the highlights. If it were accurate, according to the kelvin color temperature chart, that would be 5000-6000 degrees celsius (which it can't be because what metal can withstand that heat, right?). So I'm guessing we'd need a camera sensor with more dynamic range to guess the temp - or does anyone know the temp those things get up to?
The camera can lie a bit but the metal color seemed like it was close to the melting point of steel. Its probably the camera lying a bit, but I'd be very worried about getting the thing just explode on my back. But he probably knows better.
Yeah It seems its after sunset so the colors seem much more bright than they actually are.

after seeing so many pulse jet engine starts , i'm a bit amazed on how easy yours does it. love to see a full throttle video .
Heat shield around the fuel cell wouldn’t hurt. 😂
Out of curiosity what is the parent material of your engine? Must be some sort of high nickel alloy.
Usually inconel when it comes to turbines
@@melissabergeron3023 usually HastX in aero. I was just wondering what he in particular was using because I work in the industry. It always surprises me to see people doing these amazing things. Considering the amount of effort it takes in the professional world. I applaud him.
His website says he's using stainless on the manifold. Either way, I think full throttle would've caused a complete meltdown. Expansion and contraction will lead to a catastrophic failure eventually
@@melissabergeron3023 Normally plastic when it comes to cheap colanders.
@@melissabergeron3023 it's not a turbine it's a pulsejet. No moving parts! Fascinating. And these can be built with stainless steel, no problem.

@@G6JPG he’s clearly holding his hand out towards the camera it’s obvious he’s holding the camera with a go pro or stick doesn’t take a genius to think figure that out
@@NightmareTrash88 Since the cart (and driver!) do remain well fixed in the image, that does seem likely - but he's skilled at its use: I do _not_ see him "holding his hand out towards the camera" - he frames himself more or less from shoulders up, so you don't see muchof the arm.

@Joshua Westop Your mom?
This man did NOT look death in the eye doing this, he made death look into his eyes.
Robert I must say that I’m very impressed with your ambition, technical knowledge, and courage! 🤗 Would you like to take your jet engines to the NEXT LEVEL? My dad, Charles Dahle, was an expert on jet propulsion and he passed on some of his knowledge to me.
Your current setup wastes a LOT of energy as you know. You need to turn this wasted energy into thrust. May I suggest that you build what I would call a “steam afterburner.” (Just a name it doesn’t really burn anything)
First step is to completely enclose a jet engine with a stainless steel “steam jacket.” Similar to a water jacket on an internal combustion engine, but it houses steam instead. This housing is a simple shell with a “donut” shaped opening at the nozzle. I suggest a 1/4” gap to start with.
I would add several rows of fuel injector nozzles. Each row would be activated by an electrical solenoid and of course you are not injecting fuel, but water. Water expands 1600 times when flashed to steam! 😳 When a spray of water hits your engine, that is glowing cherry red, it will flash to steam instantly and give you a tremendous boost in thrust. 😬
There is a LOT of power in steam! Have you ever noticed that a steam locomotive did not have a transmission. It doesn’t need one!!!
Anyway, certain precautions HAVE to be made! I suggest using some pressure relief valves found on an air compressor just to be sure that you don’t have a steam explosion. 😬Also your welds have to be flawless! A tiny invisible jet of high pressure steam can penetrate your body before you can say, “I’m a dead man!” 💀 I suggest that you install a piece of armor plate with some sort of high temperature ceramic between your engine and the back of your seat just in case a weld develops a pin hole leak. You should also encourage bystanders not to get too close. High pressure steam is invisible and VERY dangerous! Navy personnel on nuclear submarines use broom handles to check for steam leaks. If the end of the broom handle falls to the floor, they know that they have an invisible steam leak. 😳
By using several rows of injectors activated by solenoids you can increase your speed gradually with each flip of a switch. You don’t want break the land speed record on your first test drive. It probably wouldn’t be that dramatic, but you never know for sure. It pays to be careful! I knew a fellow who owned a Yamaha dealership. He was testing a brand new turbocharged bike. He was cruising along at 80 mph and thought to himself, “This thing runs like crap!” Then he noticed that the choke was on, so he pushed in the choke and did a wheelie stand at 80 mph!😲 Fortunately he was coordinated enough to maintain control and lived to tell the story. Anyway, it always pays to be careful!
My inspiration for this idea came from an article about Bruce Crower’s Six-Stroke Engine. He replaced the cooling system on an engine by injecting water directly into the cylinders after the engine reached operating temperature. The water flashed to steam and generated power. He increased the thermal efficiency of the engine and eliminated the weight of a cooling system. This is an AMAZING idea! He predicted that it would almost double the fuel economy of an engine. I suggest you do an Internet search on “Bruce Crower’s Six-Stroke Engine.” Very interesting!
I would be very interested to see you try this steam afterburner idea. I have too many projects to try it myself. I think the FUN potential on this idea is pretty high! 🤔 Good luck! Be safe! 🤗 Don’t get killed!
This sounds like a jolly great idea, I'd like to pen it down with your permission.
Now you sound crazier than this guy!!!
