First a start and run of a linear pulsejet, then the run of a twin exhaust thermojet pulsejet. This are old movies from the year 2006. I almost forget about them, still I want to share them with other pulsejets enthusiasts.

double resonant combustion sort of BCVP =blast compresion valveless pulsejet. first only one side combustion then double combustion, next side ports and in the dark. some old movies from a few years ago. ... pulsejet pulsejets valveless BCVP resonant combustion pulsecombustion

What happens when you strap a powerful valveless pulsejet engine to a kayak containing a 12-year-old? Well that was my latest assignment for television and here’s some behind-the-scenes footage. I won't be able to upload any more until the program screens but watch and enjoy.

Physics students at Yale High School use a glass jar to demonstrate the concept of a simple pulsejet engine. About 1/2 tsp of fuel is placed in the bottom of the jar and a 1/4" hole is drilled in the lid. The jar is shaken to promote vaporization. Notice that some hot exhaust gas is drawn back in...

the last third of the conical tailpipe stays cold too. No mechanical valves in these motors. It is the plugs of cold air in both the tailpipe and the induction pipes that allow pressure build in the combustion region; the cold, high density air has a lot of momentum and confines the combustion a...

Heres a video of the thermalpulse 180-18 going through the throttle range. The advanced injector really does a good job. Its extremely extremely loud, and actually causes the ground to vibrate in quite a large area.

This is a small 6" Diameter ramjet engine, using the extremely high speed exhaust gas fo a pulsejet as an air source. Ramjets cant run when standing still, unless there is some outside source of high speed air. Ramjets have no moving parts and use their high forward speed to take in and compress ...

A pulsejet-powered drag boat versus a V8-powered one. It was Junkyard Megawars and I was the technical advisor for the "red" team who constructed a ramshackle boat powered by a huge (badly built) pulsejet engine. Guess which boat won :-) I’ve also been an "expert" for the UK series ScrapHeap Chal...
