摘　　要：根据国军标GJBz20339-1996要求,空气涡轮起动机在研制鉴定阶段,需要开展运转接合试验,验证其可靠性。本文通过对某型空气涡轮起动机开展相关试验,研究不同接合转速下接合时间、无量纲扭矩、最大扭矩对应的无量纲输出轴转速的变化规律,并与正常的主发起动情况进行对比。试验表明,该型起动机接合时间小于1 s,随着接合转速的不断增加起动过程中的最大扭矩逐渐降低,而最大扭矩对应的输出轴转速不断增加。According to the requirements of the national military standard GJBz20339-1996,the air turbine starter needs to carry out running joint test to verify its reliability during the development and evaluation stage.In this paper,relevant tests are carried out on a certain type of air turbine starter to study the changes of the speed of the non-dimensional output shaft corresponding to the engaging time,dimensionless torque and maximum torque under different engaging speeds,and to compare with the normal main initiating conditions.The test shows that the engaging time of the starter is less than 1 s,and the maximum torque in the starting process gradually decreases with the increasing of the engaging speed,while the corresponding output shaft speed of the maximum torque increases continuously.
