摘要
应用推力间接测量法 ,对模型两相脉冲爆震发动机的瞬时推力进行了详尽的测试 ,并依此计算了相应的平均推力。分析比较所得结果表明 ,该模型能产生很大的瞬时推力。
The instantaneous thrusts of a two phase (gasoline/air) pulse detonation engine (PDE) model under various operational conditions were obtained from indirect measurement with a piezoelectrical accelerometer,and then the corresponding average thrusts were derived.The results reveal that this model can produce appreciable instantaneous thrust in the case of the small size detonation chamber,but the average thrust is very small due to low feeding rate in the experiment system.From the detailed investigation some approaches to enhancing the average thrust of PDE were found out.
