进气系统对无阀脉冲爆震发动机性能影响试验研究
Experimental study for the effect of induction systems on valveless pulse detonation engine
摘要
Abstract
This paper addressed the operation and propulsive performance of air-breathing pulse detonation engine with inner diameters of 50mm based on the semi-free-jet simulated ground experiments. Gasoline was used as the liquid fuel and the air was supplied upstream of the air inlet by a semi subsonic free flow field. Six assembled induction systems were employed to investigate the effects of some geometry parameters, such as inlet area, blockage ratio of circumferential seam, length of conical inner body, on PDE performance. The results indicated no matter which induction system was used, PDE can be initiated by one-step with low-energy ignition system (less than 50mJ). The average thrust of PDE with six all assembled inlet systems increased as the operation frequency increased, while the increasing ratio of average thrust was faster when the area of coming air injector and inlet were both less. As the blockage ratio of circumferential seam increased, the PDE average thrust decrease slightly.关键词
