Abstract
For decades, model rockets have been built using simple recovery methods. These methods do not provide with active control, and are subject to the wind conditions. The aim of this project is to present a technologically challenging alternative. A 2-stage rocket, capable of recovering the first stage by the means of a quadcopter landing system (QLS). This system is formed by four electric motors with propellers and the flight controller. This component is the brain of the rocket, controlling the thrust of each motor in order to provide with active control over the attitude of the vehicle. This flight controller is a commercial one, commonly used for multirrotor aircraft. It must be capable of performing an autonomous landing, without the aid of any external sources. To do so, the INAV configurator has been used, where the return to home (RTH) procedure includes an auto-landing sequence. In addition to, many peripherals have been added to the mount, such as GPS and compass, furthermore, the flight controller board includes a gyroscope, accelerometers and a barometer. With all the avionics assembled, many flight and drop tests have been conducted, in order to validate the performance of the developed system. Additionally, the flight mechanics of the rocket have been studied, in order to understand the physics behind, and the 2-stage rocket has been designed, and simulated. The results obtained by the flight tests conclude that the idea is feasible, and a partial success has been achieved. The prototype was capable of flying, maintaining a stable hover state. However, the autonomous landing resulted in a crash, although it initially worked. Therefore, the idea has room for improvement and further development.
