| 摘 要： | 依据某型涡轴发动机冷运转试验数据,给出了发动机阻力矩和净力矩的计算方法。按照发动机在此温度条件下的最大允许起动时间,提出了确定发动机在该大气温度条件下起动时最小所需扭矩的方法,并通过试验表明用这种方法得到的计算结果和试验结果较吻合。

| Abstract: | Based on a turboshaft engine test data gathered during cold run,a method of calculating engine resistant torque and torque for acceleration was introduced.According to maximum acceptable start time at the temperature same as engine testing,a method for determining turboshaft engine minimum required torque for starting was put forward and it is proved by test that the calculated result is in accordance with the test data. |
