Analysis of active landing gears

Abstract

The aim of the thesis is to develop a mathematical model of the newlineaircraft with active and passive landing gears and to investigate the dynamic newlineresponse of the aircraft to bring out the effectiveness of the active landing newlinegear in absorbing severe landing impact and vibrations while taxying on newlineuneven runway surfaces during landing roll out take off and ground newlinemaneuvers The active landing gear generates active control force depending newlineon runway conditions as an input signal Among the literature available two newlinedegrees of freedom quarter model with single landing gear is the most newlinecommonly used mathematical model to investigate the aircraft dynamic newlineresponses during landing impact and taxing on the runway surfaces with newlineirregularities newline newline
