A Reusable Thrust Vector Controlled LEO Micro-Rocket

Project Singularity aimed to revolutionize aerospace by developing the smallest reusable Thrust Vector Control (TVC) rocket, enabling cost-effective satellite deployment and research missions in low Earth orbit. This prototype micro-rocket features dynamic thrust adjustment for precise trajectory control, powered by compressed CO2 at 4500 psi, with a propulsion system integrated into a lightweight structural design using 3D-printed resin, carbon fiber, and titanium components. Key systems include a four-actuator TVC mechanism, PID-based guidance with AHRS/IMU and RTK GPS for real-time corrections, and safety features like parachute deployment. The project spans phases from prototype development to space shots, targeting universities and emerging space entities to democratize access to space through affordable, customizable launches.

Thrust Vector Control (TVC) enables precise rocket orientation by dynamically adjusting the nozzle via four independent actuators that serve as both control and support, differing from traditional gimbal systems for enhanced speed and stability. Integrated with MPC (Model-Predictive-Control) algorithms, TVC minimizes errors in roll, pitch, and yaw by processing real-time data from high-accuracy sensors like AHRS/IMU for attitude and RTK GPS for position and velocity. This ideology emphasizes balanced tuning of proportional, integral, and derivative gains to ensure responsive, stable flight, reducing correction errors and enabling accurate trajectory adherence without relying on complex predictive models.
