The application is a kind of patrol flying gun
system and its trajectory correction strategy. It includes unmanned aerial vehicle,
gimbal structure and no-bracket gun; the
gimbal structure includes gun clamp, target
information acquisition device,
pitch shaft mechanism, support mechanism,
yaw shaft mechanism, suspension mechanism and firing mechanism; the ejection window of the no-bracket gun is away from the clamp, facing the ground, fixed on the gun clamp of the
gimbal structure, the gimbal structure is connected with the unmanned aerial vehicle platform through the suspension mechanism, the gun clamp is provided with the
pitch shaft mechanism, the
pitch shaft mechanism is provided with the
yaw shaft mechanism, and the suspension mechanism is arranged on the
yaw shaft mechanism; the support mechanism is arranged on the side of the pitch shaft mechanism, used for reducing the influence of the
recoil force on the output shaft of the
rudder of the pitch shaft mechanism. The application reduces the vertical size of the overall structure of the gimbal, shortens the action line of the
recoil force of the gun firing and the
center of mass of the patrol flying gun, reduces the influence of the
recoil force on the flight control of the unmanned aerial vehicle platform, and enhances the driving effect of the
rudder.
