Abstract
Analytical model of helicopter landing gear dynamics was presented for landing strike loading simulations. The influences of parameters, such as landing vertical velocity, rotor lift coefficient, gas pressure of tires, diameter of hydraulic damping holes, etc, on landing gear strike loading were analyzed. The analytical results indicate that if the designed landing velocity is increased, parameters of the landing gear must be adjusted in order to landing load decrement.
