Abstract: A gear drive, such as for an actuator, is a right-angle drive where toothed outer ridge of a face gear is coupled to teeth of a motor output shaft, and a set of planetary gears are engaged with a central sun gear of the face gear. The sun gear and planetary gears are aligned with the motor output shaft. For instance the motor output shaft may be substantially in the same plane with the sun gear and the planetary gears. From another standpoint the axis of the motor output shaft may intersect the sun gear, as well as intersecting a volume that the planetary gears sweep through as the planetary gears engage the sun gear.

Abstract: A system for restraining one or more control surfaces of a tactical flight vehicle includes a retaining frame secured at an aft end of the tactical flight vehicle and a cover plate releasably coupled to the retaining frame with a resilient lock ring. The resilient lock ring is disposed between the retaining frame and the cover plate and is deformable between a locking configuration and an unlocking configuration. A control surface restraining ring is releasably coupled to the cover plate and has control surface restraints configured to engage respective control surfaces. The resilient lock ring is configured to deform from the locking configuration to the unlocking configuration upon a launch of the tactical flight vehicle such that the cover plate becomes uncoupled from the retaining frame and may be jettisoned from the tactical flight vehicle after the launch.

Abstract: An assembly and method for assembling a projectile with a compact low friction high temperature shaft seal is provided. The assembly includes an outer shell, a rotating shaft inside the outer shell, and a seal attached to the rotating shaft. The rotating shaft can rotate independently of the outer shell. The seal can seal a gap between the outer shell and the rotating shaft.
