摘要: <正> 1.前言 飞机采用空间转轴起落架一般有两种型式,其中之一为A型(图1(a)),支柱与机轮等构件相对位置保持不变,一起绕空间轴收入起落架舱;另一种为B型(图1(b)),它有两部分运动:一是支柱绕空间轴运动,一是机轮随支柱转动的同时,再相对支柱的转轮运动。

Abstract: A method of determination of geometric parameters of the space pivot axis for a retractable landing gear with turnable wheel is proposed. In order to make the method as simple as possible, only one linear equation is used by matrix transformation to solve the complicated problem for determining these parameters. The calculation method for the direction consines of the space pivot axis, the coordinates of the shortest distance between two line segments are different from other methods and satisfactory results can be obtained.
