燃料种类对脉冲爆震发动机性能影响的研究

EFFECTS OF FUEL TYPES ON PERFORMANCE OF PULSED DETONATION ENGINE

针对自行设计的脉冲爆震发动机试验模型，研究燃料种类对脉冲爆震发动机性能的影响规律，并以汽油的实验值为例给予验证。为脉冲爆震发动机燃料的选择提供理论依据。

In order to design an advanced Pulsed Detonation Engine (PDE),the effects of fuel types on its performance were investigated.In the investigation,gasoline,kerosene,ethyne and hydrogen were taken as the fuel and the oxidizer is air.The PDE model was designed by authors.The performance of PDE,such as averaged thrust,specific impulse and specific fuel consumption,were calculated and analysed respectively with each type of fuel.The gasoline/air mixture was tested in PDE model to verify the calculating method.The experimental results were consistent with the calculated ones on the whole,so that the conclusion drawn from the calculated results can serve as theoretical foundation for reasonable selection of the fuel.
