Aircraft landing orbit design

摘要

This paper focuses on The aircraft soft-landing trajectory design and control strategy of in-depth discussion and analysis of considering The aircraft landing during the motion, and the stress is different, a mathematical model, answers the questions posed by the topic. Considered actual flight situation, we established landing cabin mathematics model description The Aircraft, of movement State, according to established of model, repeatedly set angle of pitch by using Matlab, looking for meet design requirements optimal solutions, obtained optimal design points location of cross, and ordinate; in according to geometry obtained in recent months points and optimal design points of angle, according to longitude degrees calculation method, determines in recent months points, and far months points of location. When the aircraft landing elliptical orbit, it follows the conservation of energy, so the Aircraft, in recent months points and far months points of energy equal, and due to aircraft, in in recent months points and far months points of speed are and aircraft, to months heart of line vertical, is angular momentum conservation, according to gold proportions substitution, obtained has in recent months points and far months points of speed size and direction.
