    Abstract
  • Focusing on disturbance response of the ammunition launching process，the flight dynamics model of the multi-rotor UAV （unmanned aerial vehicle） was established based on the idea of multi-body kinetics.The influences of the parameters of ammunition installation position，mass，recoil and tilt launching angle on the position，altitude and attitude disturbance response of UAV during launching were analyzed under the condition of basic stability augmentation and control augmentation flight control.The analysis showed that for the ammunition horizontal launching，the longitudinal installation position had an important influence on the disturbance amplitude of UAV horizontal position，and the appropriate rear ammunition installation position can reduce the disturbance amplitude of position.Under the condition of other certain parameters，there existed the ammunition longitudinal installation position with the least disturbance of UAV position.For ammunition oblique launching，the contour diagram of the disturbance amplitude of UAV horizontal position relating to ammunition installation position and oblique launching angle was given，which can provide reference for UAV and ammunition matching and selection.
