Research and exploration of rubber band ejection system for small vehicles

Abstract With the widespread use of small unmanned aerial vehicles, there is a growing need to improve takeoff efficiency and takeoff accuracy. The shift from the traditional rocket-boosted takeoff method to a more flexible launch method has become critical. Rapid response, simplicity of launch, flexibility of location, and low cost become necessary for new launch methods. In this thesis, we have developed a system for launching a small flying vehicle using the rubber strap ejection technique. The system mainly consists of a rotating lifting base platform, an ejection system, and a small vehicle. We analyze the various parts of the ejection system in detail, including the sliding table, the energy storage structure, the trigger, and the buffer structure, and design and test a small vehicle. Experimental results show that this rubber ejection system provides stable, accurate launches that excel in repeatability and efficiency. Specifically, the system demonstrates excellent launch stability, reliability, and launch repeatability, proving its potential in a variety of real-world application scenarios. Demonstrating robust performance and a wide range of applications, this rubber ejection system provides a new, efficient solution for launching small vehicles.
