- W3213699838 abstract "The project of “multi-stage model rocket launch and payload recovery” is one of the important projects of China Aeromodelling Design Challenge (CADC). Participants are required to complete the model rocket launch and payload recovery task through scheme designs, simulation analysis, model assemblies and flight experiments, which has high requirements for innovation and practicality in scientific research. Aiming at the design requirements of the project, this paper takes the model rocket as the object, and provides a design scheme of multi-stage model rocket with good performance. In the scheme, light materials such as hard paper, carbon rods and light wood are used as the main materials of the rocket. It combines mature model rocket engines, flight control devices, shelves products and 3D printing components. Based on the self-developed multidisciplinary design optimization and performance evaluation software platform of the aircraft, the integrated design optimization and flight performance analysis of the engine, aerodynamics and trajectory are completed, and the detailed rocket design scheme is obtained. Through the production of rocket, ground tests and flight tests, the performance excellence and stability of the scheme to complete the tasks of safe launch, rocket aviation, reliable stage separation, first recovery and second payload recovery are verified. The design scheme proposed in this paper combines the simulation calculation with the physical flight experiment through the design optimization and performance evaluation platform, and puts forward the spin disturbance rejection scheme of the oblique engines and the first-stage tails. It proposes the method of “correction of wind” that determines the launch angle according to the speed and direction of wind to increase the flight height. It has the advantages of lightweight, modularization, high efficiency, low cost and high reliability." @default.
