固冲发动机连管试验数据处理方法研究

针对固冲发动机连管试验,研究了柔性管路垂直进气推力的计算方法,进一步推导了由试验数据换算至规定状态下发动机性能参数的换算关系,并开展了两种不同富燃料推进剂的固冲发动机点火试验验证和数据处理,得到了较为合理的试验评定结果,为筛选出较优推进剂配方提供依据。

Automatic Test System Based on Virtual Instrument Technology for Flight Control Unit

This article describes the data processing method of calculating thrust in uprightness entry connect-pipe testing for solid propellant rocket ramjet （SPRR） , and deduces the conversion relationship of SPRR characteristic from test state to standard state. Finally two different kind of fuel-rich propellants in the same experiment condition are compared. The different performances are acquired on the basis of previous data processing method. The test data performance Charcteristic in standard condition is converted. By analyzing and contrasting general propellant performance, the excellent fuel-rich propellant is filtrated.
