For the case in which the rigid mode and the first n modes of a flexible airplane are considered,the body of the airplane is defined as a multi-mass equivalent system and the calculation formulas of the parameters of the system are derived,which presents a model for testing/verifying landing impact load,landing work etc.

Landing dynamic simulations are evaluated for a flexible airplane with the conventional type of oleo-pneumatic main landing gear.

For the sake of enhancing the dissipation efficiency of landing energy stored in the fuselage of flexible airplane and the passing through performance of the airplane running over the being bombed but rush-repaired runway,a kind of dual air-chambered oil-pneumatic styled intelligent bumper for controlling oil-hole damping force was designed.

Landing dynamic simulation and landing-gear optimization design are used to improve the landing-gear design for a flexible airplane.

Landing dynamic simulation of a flexible airplane is evaluated by using velocity-squared damping, poly-tropic air-compression spring, exponential tire force-deflection, and an equivalent three-mass system.

At here an analysis was carried out on the performance of the commonly used flexible amplification mechanism.
