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;...
