摘要:针对某型无阀脉动喷气发动机进行了地面静止试车试验，测量了发动机推力和压力数据，并对试验数据进行分析处理。结合发动机燃烧室压力数据，分析了该型脉动发动机高频工作的机理和过程。针对推力测试数据的特点进行了数值模拟，分析了直接推力测试方法导致推力数据的幅值调制特征，并对目前直接推力测试方法中的不足提出了两种改进措施。

Ground experiment of the non-valve pulsejet engine was finished. The thrust data and pressure data of the engine were measured and analyzed. The high frequency work principle and process of the pulsejet engine were researched combined with the pressure data. Be directed against the characteristic of the thrust data，digital simulation was done，which proved that the direct thrust test could cause amplitude modulation. Direct thrust test was deficient，and two kinds of improved measure were brought forward.
