| 摘 要： | 大型军用运输机、民航客机广泛采用可视为前三点式(前起落架组、左主起落架组、右主起落架组)的多支柱起落架布局方案.通常,此类飞机的最大起飞质量高达数百吨,起飞滑跑速度也较大,因此,起飞情况是起落架强度设计的重点.本文基于前三点式起落架计算理论,以及对An-124、An-225飞机起落架设计方案的研究,提出一类串列多支柱多轮主起落架的起飞情况地面载荷算法.

| Abstract: | The landing gear system with multiple struts properly regarded as tricycle single landing gear strut layout has been widely used in super large-size military aerotransport or civil jumbo jet.In general,MTOW(Maximum Take-Off Weight)of these super large aircrafts reach up to hundreds of tons and take-off taxiing velocities of them are very high.Therefore ground loads of take-off taxiing are critical strength design conditions.Based on theories of tricycle landing gear layout and studies of both An-124(Ruslan,... |
