针对某型涡轴发动机在外场使用中依靠人工估算循环寿命的消耗情况,制定了发动机循环寿命、直升机训练起落次数和飞行时间的计算方法,研制了航空发动机工作历程自动记录系统。该系统不仅可实时、科学准确地记录发动机的工作时间、消耗的循环数和超转幅值,还可记录直升机飞行时间和训练起落次数,系统具有自检、外场校验、参数预置等多种功能,通用性和适应性强。研制的系统已推广应用于国产和国外引进的11种机型的不同发动机上,经数百台的装机使用证明,其工作稳定,安全可靠。
Aiming at the consumption of a certain type of turboshaft engine in outdoor field by artificial estimation of cycle life, the method of calculating the cycle life of the engine, the helicopter training landing and landing time and the flight time was worked out and an automatic recording system for aeroengine working course was developed. The system can not only record the working hours of the engine, the number of cycles consumed and the overshoot amplitude of the engine in real time and in a scientific and accurate manner, but also record the helicopter flight time and the number of launching and landing times. The system has many functions such as self-checking, field checking, parameter presetting and so on Function, versatility and adaptability. Developed system has been widely used in the introduction of 11 kinds of domestic and foreign models of different engines, installed by the use of hundreds of proof, its work is stable, safe and reliable.
