Process and Mathematic Model Study of a UAV during Taxing and Takeoff

During taxiing and takeoff UAV has unique dynamical characteristics different from that of flight, as regards a certain type of domestic UAV, the whole process of a UAV during taxiing and takeoff is described, the strength pressed on the UAV in every stages are analysed, and the motion equation during each stage are established. In the ground motion model, the elastomeric model of tires and landing gears is applied. The simulation result proves that the model almost accurately represents the actual dynamical characteristics of the UAV during taxiing and takeoff.
