10 lb thermojet valveless pulse jet engine

This is a 10 lb thermojet valveless pulsejet engine, all tig welded stainess steel. It is self starting, most pulsejets need to be provided with compressed or blown air in order to start the engine. This engine you can either light the propane with a torch or gril lighter, or a spark plug, and it will start right up. The engine is a valveless pulsejet with no moving parts, and easily self starts on propane, just turn on the ignition and turn on the fuel.... A valveless pulsejet is a unique type of engine with no moving parts. Unlike ramjets, which must have air blown into them at high speed, either by a blower or by traveling very fast, pulsejets can run while completely still. They can be throttled typically between 10% and 100% thrust in the blink of an eye, and dont require any spool up time like turbines or turbojets. Because they have no moving parts, valveless pulse jets are much easier to own and operate than RC turbines. For the cost of a ducted fan setup, you could have your own real, high speed RC jet plane. The truth is that by the time you add up turbojet planes engine weight, fuel and oil pump weight, the computerized control system, and any onboard starting systems, you not only have a small fortune invested in the plane, but its also quite heavy. Pulsejets can be made extremely light weight, and even valveless engines are capable of pumping their own liquid fuels by the venturi effect. All you then need is your standard reciever and servos and a small ...

Pulsejet engine vertical launch - vtol pulse jet rocket

Pulsejet engine vertical launch - VTOL vertical take off and landing rocket www.beck-technologies.com Pulsejet engines have been overlooked as a propulsion system because most people think they are low power and inefficient. Pulsejet engines actually have quite high power to weight ratios, comparable fuel consumption to RC turbines, and have few or no moving parts, meaning they cost about 1 as much as a hobby turbojet and rarely need any form of maintenance. This is a video of an old demo we did, to show the potential of pulsejets. The engine is an old 1960's era dynajet, which is not anywhere near optimized, yet it still has impressive lift performance. Sitting on the ground most people dont see the potential these engines have, and are content with saying they are useless, when that couldn't be further from the truth. Pulsejets could be used on anything from RC hobby hovercrafts and RC VTOL planes, to small UAV's, and many other things.

Dynajet pulsejet engine overview & starting

www.Beck-Technologies.com check out our site for tons of info on pulsejets and hobby engines and supplies & more To watch a video of this engine doing a vertical lift demonstration check out www.youtube.com A little video showing the Dynajet pulsejet engine, the parts, how they work, and about the engine, followed by actually running it. Its a tutorial video, the point is to show all the parts and explain them, if you are one of the impatient instant gratification types who dont care about all that and just want to see the engine run, dont complain, I didnt make this video for you. The Dynajet is a valved pulsejet engine, the valve is the only moving part, and is responsible for keeping air from flowing out of the valve head. In order to start the pulse jet, you need to blow a little bit of compressed air, which will open the valves, and fuel and air will move into the combustion chamber. When you provide a spark, the fuel burns and starts the engine running, and it no longer needs a spark once it is sustained. As the fuel burns it creates a pulse of thrust, causing a jet of gas to shoot out of the back of the engine, after the fuel has burned the pressure inside is below atmospheric, and the pulsejet pulls in another charge of fuel and air, which gets re-ignited by some hot gas remaining in the engines tail pipe. The fuel air charge then burns again, and produces another pulse of thrust, and the cycle repeats at about 280 times a second! Pulsejets are a simple type of ...

5 lb thrust pulse jet engine with dyna jet red head.

Pulse Jet with Dyna Jet Red Head running on Propane produces 5 lbs of thrust on the test stand. I used the German V1 research data to design the combustion chamber, cone and tail pipe of this engine. I used college research date written by 3 different students in 3 different colleges to make other changes. Research data says, a longer tail pipe produces more kenetic energy causing the engine to take in a larger volume in air and fuel and this will increase the thrust. I ran the engine several times on propane and made several changes to the fuel orfice. Then I took this video which is probably the 8th or 9th test run. This engine is 50% throttable and it is running amost full power for about 2 minutes in the video then. I turned down the fuel pressure until the engine stopped. The original Dyna Jet Head and reed valves were used in the engine. Total run time so far about 60 minutes. The engine is running on propane which produced about 97% of the power of gasoline but propane is a lot easier to regulate. The best part about this design is the lower combustion chamber compression ratio does very little damage to the reed valves. The German pulse jet design is not suppose to produce more thrust it increases the reed valve life to a minimum of 1 hour. Some of the German reed valves lasted for 24 hrs in a static test run. The longer tail pipe also helps to suck the combustion chamber flame away from the reed valves to keep them from getting hot. The engine is running on 8 lbs ...

Pulse jet engine model t ford based ignition system

www.beck-technologies.com This is one of our Model T Ford based ignition systems. We can custom make them with any number of types of switches, and even arming keys. All our ignition systems use newly manufactured coils. Why use an ignition system from a car from 100 years ago? Because the model T ford 'buzz coil' ignition coil is a simple, rugged, reliable self contained unit. It was designed to run continuously for long periods of time while being bumped around on rough roads and in bad weather. It produces many sparks a second, which is perfect for starting all kinds of engines, like pulsejets. With the high frequency spark, the pulsejet will ignite quickly and easily. With cheap sparking systems that produce only one or two sparks a second, the spark must be timed with the proper fuel air mixture ratio at just the right time. High frequency sparks on the other hand will ignite the proper fuel air mixture as soon as it contacts the spark. Another thing with pulsejet engines, is that the spark plug gap can be wider than normal engines. The wider the gap the more exposure it will have. The model T coil produces a good hot spark that can ignite liquid fuels like kerosene or diesel fuel, but is still relatively safe. If you get shocked accidentally with it, its painful, but thousands of times safer than transformers. NEVER attempt to use high voltage neon or TV microwave transformers, they can kill you faster than you can blink. Check out our other videos and dont forget ...

20lb thrust pulse jet engine with argus valves

This pulse jet engine was designed to be 20 lbs of thrust. It has 32 Argus type valves. I have done 3 test runs about 2 minutes each run. Valves show no signs of getting hot and no valve damage. The engine is running on propane with fuel injection directly into the combustion chamber. It starts extremely easy and runs very nice. I started the engine on 8 psi propane gas pressure the tank is too cold to get anymore pressure it was 40 degrees F in the work shop the tank needs to be warmer to get more pressure. The engine throttles nice I reduced the propane pressure down to 4 psi yesterday before the engine stopped running. I should be able to get 15 psi propane pressure with a warmer tank. The fuel injector I am using should throttle the engine up to full power. I will put it on the test stand later this week to check the actual thurst. After some more testing my next project will be a 50 lb thrust pulse jet engine then 250 lbs thrust then 500 lb thrust then a full size German V1 Rocket Engine. Reed valves are made from .010" blue spring steel. I had to build my own test equipment for testing the valve design to make sure they would work correctly in this engine. My experements with other engines last winter I learned how to keep the valves from getting hot, how to keep valve from getting damages, how to extend the life of the valves, how to throttle an engine 85%.

Pulsejet long-ez now very fast!

I've replaced the original PJ8 pulsejet prototype with the pre-production (second) prototype on which all the manufactured engines are based. The production engines actually produce quite a bit more than 8lbs of thrust and (as you can see in the video) this really makes a big difference to the Long-EZ's performance. This was a short flight. These engines are thirsty, the Long-EZ tank has a small and I don't think I filled it all the way. I've now reflexed the ailerons of the Long EZ, setting them to be about 3mm up at the trailing edge. This has vastly improved the handling of the whole model and improved elevator authority a lot (it caught me out when flaring for a landing) but now, the plane no longer drops a wing and I was able to control the bounce very easily. Next up: the pulsejet-powered ARF Bobcat -- it's nearly done!

Valveless pulse jet thrust augmenter

This is a short video clip showing one of our 4lb thermojets running with a thrust augmenter. The thermojet is a valveless pulsejet engine with no moving parts, and the augmenter also has no moving parts. The thrust augmenter increases the thrust output by using the super hot exhaust gas to heat and expand additional air, with no extra fuel consumption. Valveless pulsejets can be made very light, with no moving parts, and by themselves can have similar or better fuel consumption compared to hobby turbines / turbojets. When a thrust augmenter is added the efficiency is increased even further. This thrust augmenter boosts the engines thrust by about 40%. Not bad for a specially shaped tube.

Despite the improvised nature of the proof of concept test, the turbine reached up to 3500 RPM at low throttle with the pulse jet engine positioned far away from the turbine. Because there was no load on the turbine, the engine was not run at high throttle, to prevent it from over-spooling and ripping apart. A more advanced setup could be used to power a generator, or other devices. www.PulseJetEngines.com

Valveless pulse jet cycle animation

Here is an animation of the basics of what goes on inside a valveless pulse jet engine. At the start cold air is blown into the engine where it mixes with fuel. This fuel mixture burns rapidly, expanding out both the intake and exhaust pipe of the engine. The gas shoots out of the engine so fast that it leaves a vacuum behind it, and atmospheric pressure forces more air back into the engine, mixing with more fuel, and hot exhaust still trapped inside the engine lights the new fuel mixture and begins the cycle all over again. This happens very quickly, about 150 times a second for a medium size engine. For more information, plans, and more visit our site at: www.PulseJetEngines.com

Jam jar pulse jet - in slow motion

Slow motion study of a pulse jet "jam jar" Reynst experiment. The seven second run near the beginning of the video is the same run shown at 300 fps at the end of the video. Lighting was challenging for the HS camera. If you film it in bright light, you can't see the flames, if you film in total darkness, everything looks grainy. The flames are not real bright while it is running, though the initial, very unusual grape-cluster-like fireball is pretty spectacular. - The 600 FPS shot, was only a ---3 second run--- in real time. Although grainy, you can see each cycle. - HOW TO: 1/2" hole used for hole. In order for the jar jet to work, the jar has to be cold. The cold surface cools the gases, creates a partial vacuum, and draws in air and if a flame remains from the last cycle, it will ignite the fresh charge. The cycles operate around 30-40 a second, with occasional sputters. We used some very old model airplane fuel for these shots but it worked fine. Use caution if you decide to do this, adult supervision, safety glasses, etc. The jar will normally crack after a successful run. -- By studying this in high speed, you might decide to make some modifications to improve firing or efficiency. Maybe put a metal nozzle inside, or a metal heatsink at the bottom or a thin wire to act as a glow plug across the flame jet... see how long you can make your version run.
