The has been constructed a mathematical model of aircraft parallel plane movement along the runway in complicated conditions, when lateral component of the aircraft ground speed is available. The aircraft is represented as a system of elastically interconnected absolute solids and a holonomic model of the wheel rolling with pliant periphery has been obtained. The stationary modes stability as well as the self-oscillation parameters and modes of their setting have been considered. It has also been considered how the choice of the aircraft estimated scheme affects the results of the mathematicalmodeling of the oscillations of the main landing gear, hull and the components elastically connected to them. Attention has been paid to the possibility of the airframe main components inner resonance appearance and the character of their oscillations during and in proximity of the resonance has been investigated. Dynamic programming method application for optimizing the aircraft oscillation protection systems has been discussed. Ways of the above mentioned method application in designing the airframe components suspension points have been elaborated5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
