Reaction Wheel Based Rocket Active Spin Stabilization, Tanuj Vemuri

Electrical Engineering

Cal Poly Space Systems is the high-powered and experimental rocketry club at Cal Poly SLO. They aim to design, test, and launch fully integrated launch vehicles. In order to create efficient and reliable vehicles, stabilization systems must be implemented. One parameter that can be actively stabilized is the vehicle’s roll. The roll of the vehicle can have noticeably effects on vehicle performance, as uncontrolled roll leads to decreased system stability in flight. Un-controlled roll can also have negative impacts on the quality of onboard video, which is used for post-flight analysis and marketing.

Reaction wheels are a popular method for …
