It rotates to provide weight for the personnel, and that rotation gives it gyroscopic stability.

Such round shot would benefit from gyroscopic stability, thereby improving their trajectory, until the advent of the ogival shell.

All involve spinning the disc to give it gyroscopic stability, and accelerating its mass to a certain velocity.

The spinning motion gives the yo-yo gyroscopic stability.

The main body of the spacecraft was spun at 30 revolutions per minute (rpm) to impart gyroscopic stability to the satellite in the Earth's gravitation field.

The basic design of the entire series featured a rotating section, the "Wheel," to provide gyroscopic stability.

Florine chose a co-rotating configuration because the gyroscopic stability of the rotors would not cancel.

The method involves spinning the projectile at 6000 revolutions per minute to achieve gyroscopic stability.

Due to the gyroscopic stability of the Dirtsurfer, speed is limited only by the wind, with recorded speeds well over 40 mph on a flat surface.

Also, a faster-spinning discus imparts greater gyroscopic stability.
