Design of A 3-DOF Thrust Control System for Rocket Engines

Abstract

Within the scope of this project, a system that can direct the thrust of solid propellant rocket engines will be built. This method will provide high mobility for hybrid and liquid propellant rocket engines. The rocket will react to external effects (wind, etc.) that may occur while cruising. Sensors such as GYRO and IMU on the system are called TVC (Propulsion Vector Control), which provides the balance of the rocket by directing the thrust in the opposite direction of the rocket's trajectory. It also meets the requirements for angular speed control, route linearity and immediate response to emergencies. The design of the system has been created according to geometric properties, kinematics and forces, energy requirements, safety, cost, control methods requirements. Regarding the management of TVC, a literature review on TVC system design has been made first. Analyzes will be made taking into account the thrust and combustion time of the engine used. The system will be designed according to mechanical and avionic design principles. All of this is filtered out by focusing on the relevance, adaptability, economy and consistency of production. It is aimed to solve and support the software and algorithms to be created (differentiated design), thrust vector angular position and other motion problems through flow charts. With the possible design we mentioned in the report, we aim to solve similar examples of our project and to eliminate the question mark in our minds to some extent. Our project management will be carried out in accordance with work schedules, risk management and research facilities. We aim to work on projects such as literature research, system conceptual design, system visual design, preparation of the final design and the final report of the system.
