According to the multifunctional unmanned aerial vehicle vehicle-mounted pneumatic control valve system, the wheel well door, the landing gear and the brake system are controlled in a pneumatic mode.

Description

technical field [0001] The invention relates to the field of airborne pneumatic control technology, in particular to a multifunctional unmanned aerial vehicle airborne pneumatic control valve system. Background technique [0002] In the field of remote control model aircraft, that is, unmanned aerial vehicles, most of them use non-retractable landing gear. In order to ensure the strength, the material of non-retractable landing gear is mostly made of carbon fiber or alloy structural steel. The disadvantage is that it has an impact on the aerodynamic performance of the aircraft. There are models of light aircraft with retractable landing gear, but they all use hydraulic landing gear retractable system. The disadvantages are: complex structure, heavy weight, high manufacturing difficulty, long processing cycle, and high processing cost. Pneumatic landing gear retraction systems began to appear, and the corresponding UAVs will be equipped with airborne pneumatic control valve s...
