Spinstabilized
Spinstabilized, or spin-stabilized, describes systems whose orientation is maintained primarily by rotation about a fixed axis, using angular momentum to resist external torques. In aerospace and mechanical engineering, a spinning body exhibits gyroscopic effects that provide passive attitude stability without continuous active control.
The mechanism rests on conserved angular momentum. A rapidly spinning mass tends to keep its spin axis
Applications and examples include early spacecraft and satellites that used spin stabilization to retain a coarse
Advantages of spin stabilization include passive stability, mechanical simplicity, and low power requirements, making it attractive
