INTRODUCTION

An exactly analysis of the landing gear, as designed on modern aircraft’s, is necessary to

There are several systems that control the landing gear during different flight phases, these systems must somehow be activated at the right time. This is done by the basis lay-out slowly evolved to a retractable lay-out which is standard for large civil aircraft these days. The landing gear is also the only way to control the aircraft direction on the ground. Due to the excessive use of the landing gear on the ground, the tires and wheels must be able to endure this stress for longer periods of time. But if they need to be replaced, it must be a easy routine job which does not require the disassembly of the landing gear. One of the main causes of wear to the tires is braking, because the tires are kept on the skid limit. Before the brakes are used during landing, the aircraft has made a touchdown. This touchdown requires another landing gear system, namely the shock absorbers which reduce the impact on the rest of the aircraft. Some of these systems are required by law, especially for civilian aircraft. The source that is most used for this chapter is: Technical training manual (1999-2000).

1.1 General description

The landing gear or undercarriage of the A320 has four main functions. It separates the aircraft from the ground, allows the aircraft to manoeuvre on the ground with a steerable nose wheel, it softens
