Abstract:

Catapult launching can effectively reduce the energy consumption of UAVs in the take-off stage, increase the payload, and improve cruising mileage. This study investigated the compressed air ejection system for fixed-wing UAVs through experiment and simulation. Based on the overall thermodynamic design of MATLAB, the compressed air catapult prototype was established successfully, and detailed experimental tests were conducted to evaluate its performance. A dynamic simulation model was further established to grasp its aerodynamic action process. The variation curves of pressure and motion parameters such as velocity, acceleration, and displacement in the launching process of UAVs were obtained. The different parameters, like the effects of different working pressures on the performance of the catapult launch prototype, concrete working process, ejection performance of the catapult launch prototype, and the flow characteristics of compressed air and its effect on the piston were analyzed in detail. The experimental test results show that the catapult prototype can realize the catapult take-off of the 50 kg UAVs at a speed of 25.11 m/s. Similarly, its aerodynamic mechanism is obtained through simulation research.

Key words: compressed air ejection, development of catapult prototype, experimental test, dynamic simulation
