Abstract

Pre-spinning the wheel is the proposed solution to the elimination of aircraft landing smoke caused by high tire tread temperature during touchdown. In this paper, a case study of the aircraft's main landing gear has been simulated for a single wheel, using a coupled structural - thermal transient analysis in ANSYS to estimate the tire tread temperature for a typical landing and for when wheels are pre-spun, in order to validate the technique of pre-spinning the wheel; and to calculate how much pre-rotation is enough to avoid aircraft landing smoke.

通过预旋转轮子来防止飞机轮胎过热
针对飞机着陆过程中轮胎胎面温度过高而产生的着陆烟问题,提出了预旋轮的解决方案。本文以某型飞机主起落架为例,采用ANSYS中的结构-热耦合瞬态分析方法,对典型着陆和预旋转时的轮胎胎面温度进行了仿真,验证了预旋转技术的有效性;并计算出多少预旋转才足以避免飞机着陆时产生烟雾。
