一、问题的提出AN-24航空发动机是从苏联引进,装配在安24民航客机上的航空发动机,是我国目前小型机场短航线上的主要机种.该发动机在使用过程中和在试车台上曾多次产生故障,表现为振动加速度值及变化范围超过规定的标准.由于这种振动超差常常迫使发动机提前维修更换,甚至被迫空中顺桨停车,影响航班正常飞行,造成严重的经济损失和危及乘客和机组人员的人身安全.
First, the issue put forward AN-24 aero-engine is imported from the Soviet Union, assembled in An-24 civil aviation passenger aircraft, is China’s current small airport short flight on the main models. The engine during use and in the test bed Has repeatedly failed, the performance of the value of the vibration acceleration and the scope of change beyond the prescribed standards.Because this vibration overshoot often force the engine repair ahead of replacement, or even forced air parking, affecting the normal flight, causing serious economic losses And jeopardize the personal safety of passengers and crew.
