Advanced chinese-style valveless pulse jet engine, running on propane, it gets so hot that the stainless steel starts to burn! • A valveless pulse jet 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. Pulse jets 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 pulse jet, 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 system, you can have your own real high speed jet, for a tiny fraction of the cost of a RC turbine engine alone. • For lots more info visit: • http://www.PulseJetEngines.com
