Modeling And Simulation Study Of The Uav System

The work present here is concerning with the technology about the Uninhabited Combat Air Vehicles(UCAV) or Unmanned Tactical Aircraft(UTA). The purposes of this research are to make clear the mission concept, the constraint factors of the subsystems of UCAV/UTA and their relations, and to build up a rational simulation system for the unmanned aircraft system, which provide a favorable system for analyzing the tactics mission of UCAV/UTA. In order to do so, at first, the concept of UCAV/UTA is explained. Then the mechanism and working modes of telecontrol and telemetry subsystem are analyzed, and the mathematic model is set up for the communicating part of the subsystem. The inner and outer flight control loops of the unmanned aircraft have been also designed, with the dynamic model of the frame involved. The complete mathematic model and basic simulation system given here can present the dynamic characteristics of the unmanned aircraft. Moreover, as an example, the flight control system is designed for the unmanned aircraft Ba-2. Finally some prime investigate results on UCAV抯 tactic mission are provided through a representative calculation.
