Design and Analysis of Terrain-adaptive Bionic Landing Gear System

Abstract

Nowadays, the wheeled landing gear and the skid landing gear are used a lot in the vertical takeoff and landing aircraft (VTOL), which have shortages and can't meet the military and civilian needs in new area. So a new kind of terrain-adaptive bionic landing gear is proposed which can fulfill the requirements of large load and small weight, can make the VTOLs landing on rough terrain, great slope and step floor. In this article, the design principle of the landing gear is introduced at first. The specific composition and working process are given. Then the design method of one-leg system is detailed described as an important part. And through dynamic analysis and virtual prototype simulation, the feasibility of the design is shown at last. And from the jobs we have done, the terrain-adaptive landing can be achieved, and simulation result show that the VTOL can be landing successfully on some complex terrain through adjusting the orientation of the landing gear. Compared with the traditional landing gear, this design can be achieved in engineering and it has subversive significance.
