Abstract

The invention relates to a movable unmanned aerial vehicle gas-liquid power ejection system, and relates to the technical field of unmanned aerial vehicle launching. According to the system, an ejection mode of an unmanned aerial vehicle is changed, reverse thrust generated from high-pressure water jetting is directly used as ejection power, an ejection speed is increased by means of pulleys, theenergy secondary conversion is avoided, the energy efficiency is high, the system structural composition is simple, the speed increasing ratio is large, the maneuvering flexibility is good, the problems of electromagnetic interference and the like are avoided, and the system can be widely applied to catapult-assisted take-off of -fixed-wing unmanned aerial vehicles of various types.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a gas-hydraulic power ejection system for a movable unmanned aerial vehicle. Background technique [0002] Catapult launch is a take-off method often used by current fixed-wing UAVs. It can significantly increase the gliding speed of the UAV under the action of external force and shorten the take-off and gliding distance. At present, the main ejection methods of UAVs include elastic ejection, electromagnetic ejection and pneumatic ejection. [0003] Among them, due to the limited energy storage of elastic ejection, the ejection power is very small; although the mechanical structure of electromagnetic ejection is simple, the electronic control device is complex, and there is still a "congenital" defect, that is, it will generate strong electromagnetic interference, which will affect electromechanical equipment and electronic control. System reliability. [0004]...
