Valve less pulsejet engine can be used to probe models aircrafts, it uses my own ideas to simplify design, manufacturing, and enhance performance.If you ask how it works? The answer : it is the same principles of common pulsejet engines, but i get ride of the mechanical valves and use my own modify of Tesla Valve to make a high pressure zone to prevent the expansion to go forward, then it uses the suction effect of backward expansion to get fresh air to the burning chamber.The hollow duct tube in the center service two purposes, cooling and increasing the thrust by using the air-multiplying effect (Dyson effect).
