Modeling and Simulation Research on Tailless Unmanned Aerial Vehicle

Unmanned aerial fighting platform is of vital importance in future war. Tailless unmanned aerial vehicle (TUAV) not only has the ability of stealth, but also has good maneuverability. In order to realize super maneuverability and reconfigurable ability, the description of the flight state of TUAV, which depends on the syncretic control technology of aerodynamics control flips and thrust vector, is necessary for the research. In this paper, the six-degree-of-freedom (6-DOF) mathematical model of a TUAV was established on the basis of theoretical analysis. Since the aircraft mathematical model with rigid body characteristics and aerodynamics data are not dealt with linearly, the established model not only reflects roundly the practice characteristics of TUAV, but also takes on general quality. At last, the flight digital simulator was developed under the environment of MATLAB7.0/Simulink. As a result, the model and simulator are validated by the digital simulation
