A study of ground maneuver stability of multiple-bogie undercarriage

Set up a kinetic analysis model to study ground-maneuver-stability of multiple-bogie undercarriage. The calculations and simulations demonstrate that the allowable nose wheel steering angle and aircraft's ground-maneuver stability could be improved by decreasing height of C.G of aircraft, increasing aircraft's weight, decreasing aircraft's velocity and decreasing engine thrust on condition that aircraft's configuration is identical and aircraft's safety and performance do not reduce.
