  • 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:

  • How To Start A Valveless Pulse Jet Engine This tutorial video shows the equipment, and procedure used to start a small valveless pulsejet. The engine was custom made with integrated mounting system and fixed position fuel injector. 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 battery to power it, rather than a large battery to power a fuel pump.
  • Elektra II Valveless Pulsejet Thrust Measurement Run 3 of 3 By this point the front pair of skate wheels was melting on the inboard edges from the engine's heat. Number 3 of 3 test runs to measure the thrust of the Elektra II valveless Pulsejet - Results were approx 1.9 pounds thrust after calibration corrections (using known weight to establish correction factor for cheap fishing scale).

  • 10 Lb Thermojet Valveless Pulse Jet Engine This is a 10 lb thermojet valveless pulsejet engine, all tig welded stainess steel.

  • 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.
  • Valveless Thermojet Pulse Jet Engine This Engine was purchased on Ebay. I modified the Injectors to a smaller size and increased the flare of the tailpipe. The engine is started with a torch to the intake as the propane is turned on. Once the engine is rumbling the propane is turned up slightly (a sweet spot is present) and the engine will start to pulse. If the propame is turned up too far (past the "sweet spot") a shot of air in the intake will start it.

  • Jim's Valveless Pulsejet Engine A Tutorial for lighting a homemade Valveless Pulse Jet engine
  • My most successful valveless pulsejet This is a demo of my "M40E" pulsejet, running at various power levels. It starts out at 5 lbf thrust, and then I increase the power to 17 lbf, and further to 25 lbf; then, I throttle back to 5 lbf again. The hand signals are an effort to indicate the power levels numerically, as described. This pulsejet starts easily and can be immediately throttled to zero net thrust (sustaining smoothly)--after which it can be immediately throttled to any power level up to its max of 28 lbf. Combustion chamber is 4-inch OD tubing. Fueling is gaseous propane, through advanced modulating injector assemblies. This engine would lead to a multiple-intake prototype with 4 intakes, capable of powering a manned aircraft demonstrator. I've suspended my development work for the time being, and moved to gas turbine projects instead.

  • Advanced Thermalpulse "Chinese" Valveless Pulsejet Engine www.Beck- Advanced chinese-style valveless pulsejet engine, running on propane, it gets so hot that the stainless steel starts to burn! A valveless pulsejet is a type of jet engine with no moving parts. It can run statically and be throttled over a wide range. Unlike turbojet turbine engines they do not have any spool up time, and can be throttled to back and forth from minimum to maximum throttle many times a second. While they do get extremely hot, they are surprisingly efficient compared to hobby RC turbine engines. Pulsejets have no moving parts, and they use sound waves to compress the fuel air mixture. This natural compression is very efficient, compared to mechanical compression of turbines and turbojets. Because of this a good valveless engine will actually be more fuel efficient than the average hobby turbine, and if you use a thrust augmenter duct with the pulsejet, the efficiency can easily jump to twice that of a turbine. When you combine this, with the fact that they have no moving parts, require no complex precision machining required by extremely high RPM parts, you have a very attractive engine, that costs 10 times less than a cheap hobby turbine. No moving parts also means no real maintenance. Hobby turbines should be taken apart and inspected each run, and many parts like the bearings need frequent replacement, most hobby turbines need a complete overhaul of all moving parts after 20 hours. For not much more than the cost of a ducted fan ...
