Experimental investigation of air-breathing valveless pulse detonation engine;
吸气式无阀脉冲爆震发动机试验研究
This paper addressed the nozzle effect on the performance of an air-breathing pulse det- onation engine(PDE)by multi-cycle detonation experiments.
分别对采用不同面积比、不同长径比的收敛喷管、扩张喷管和收扩喷管的吸气式脉冲爆震发动机(PDE)进行了多循环爆震试验研究,着重研究了不同工作频率下喷管面积比和长径比对吸气式PDE性能的影响。
Based on the test of the single centrifugal fan, suction characteristic of the centrifugal fan in series is carried out.
为此,在离心风机单机吸气性能试验的基础上,进行了离心风机串联吸气性能试验,得出了串联吸气性能与单机吸气性能的关系,以及适于串联的工况条件,为串联风机的参数选择提供了试验依据。
