Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles (UAVs), in particular to a design method for a small unmanned aerial vehicle (UAV) chain drive modularized step-by-step acceleration electric catapult. Background technique [0002] The use of small drones in the civilian field is becoming more and more extensive, and the impact is becoming more and more far-reaching. It is widely used in aerial photography, environmental monitoring, power inspection and many other aspects. This makes the innovative research on the ejection device of light and small unmanned aerial vehicles more and more people's attention. [0003] At present, the catapults of most light and small unmanned aerial vehicles on the market are simple in structure, low in manufacturing cost, and use rough rubber bands for electric ejection. The acceleration during the sliding process will become smaller and smaller, resulting in longer acceleration time. As for oil-powered UA...
