Design and Development of Valveless Pulsejet Engine

Development of Valveless Pulse jet engine requires the careful design of an inlet, combustor, and exhaust pipe. Geometrical design and usage of materials, which primarily affects engine efficiency and performance. The design of an inlet ensures the amount of air allowed to flow towards the combustor. The thrust of the pulse jet engine depends upon the overall length and volume of fluid flowing through the pipe. Thus, the inlet pipe should be wide enough to flow towards the combustor. The design of the combustor should ensure the actual mixture of compressed air with the fuel. The exhaust pipe must be designed to allow enough expansion for the gas to provide power. The exhaust pipe should be significant in length to ensure the creation of strong pressure waves which will continuously run the engine. Aim of this research work is to develop the Valveless Pulse jet engine to operate with Liquefied Petroleum Gas. The significant effort on using the experimental method to attain the whole configuration of the valveless pulse jet engine was focused, and exit temperature for various run was presented.
