摘　　要：为验证吸气式涡轮冲压发动机(ATR)模型的精度,参考国外公开的试验数据,对现有ATR模型进行了修正.使用修正后的模型模拟了ATR节流性能和过渡态性能.计算结果和试验数据对比表明:高换算转速条件下的计算结果与试验结果相对误差在1%以内;低换算转速条件下,由于燃气发生器燃气性质和燃烧室出口燃气性质不准确,相对误差有所增加,但未超过5%.全换算转速范围内各参数变化趋势相同.对比结果表明该ATR模型可以很好地模拟ATR慢车以上工况的性能,同时证明了现有ATR模型的可靠性和合理性.In order to verify the validity of airturboramjet （ATR） model, modifications were made with reference to public experimental data. ATR throttle performance and transi ent state performance were simulated by using the modified model. Comparisons between the calculated results and experimental data show no more than 1% errors in the modeling preci sion at the high corrected rotating speed and no more than 5 % errors at the low corrected ro tating speed. The increasing errors at the low corrected rotating speed are due to the inaccu racy of gas property at exit of the gasgenerator and the burner. Trends of all the parameters obtained from the model agree well with the experimental data above the idle speed. The comparison results demonstrate the high fidelity of this ATR model, while the rationality and reliability of existing ATR model are also demonstrated.
