Design and computation of landing gear damping system of advanced aircraft

Takeoff and landing are the most important stages of the aircraft flight. The flight safety depends on the landing gear at these stages. Therefore, the design and computation of landing gear damping system is one of the most important tasks of the aircraft development. When computing the landing gear damping system, it is required to use methods of numerical simulation of the motion of a system of rigid bodies with holonomic constraints. The most appropriate approach is to use a technique based on the Lagrange equations of the first kind and the object representation of models. The considered technique allows the use of a formalized approach to the description of models, the computation of arbitrary kinematics, as well as the introduction of automatic control algorithms into the system, which is important in the design of adaptive systems. Adaptive damping is one of the promising areas in the development of the landing gear. The effect of the use of adaptive landing gear damping system is expressed in reducing the maximum dynamic loads on the airframe, and as a consequence, through extending life, increasing comfort, and improving operating conditions.
