Abrégé
A control surface deployment apparatus having a base part, a drive actuator operably installed adjacent to the base part and having a drive actuator shaft extending beyond the base part, a knuckle part installed on the drive actuator shaft so as to selectively rotate therewith, a hinge part pivotally installed on the knuckle part as through a hinge pin, a fin rigidly installed on the hinge part so as to extend away from the knuckle part, and a spring biasing element configured to pivotally bias the hinge part relative to the knuckle part.

Abrégé
We claim a hammer driven actuator that uses the fast-motion, low-force characteristics of an electro-magnetic or similar prime mover to develop kinetic energy that can be transformed via a friction interface to produce a higher-force, lower-speed linear or rotary actuator by using a hammering process to produce a series of individual steps. Such a system can be implemented using a voice-coil, electro-mechanical solenoid or similar prime mover. Where a typical actuator provides limited range of motion or low force, the range of motion of a linear or rotary impact driven motor can be configured to provide large displacements which are not limited by the characteristic dimensions of the prime mover.

Abrégé
A spring biasing locking mechanism is provided for a step and repeat motor. The motor includes a base having a channel, an output member in the channel, at least one translator drive element and first and second clamping elements. The spring biasing locking mechanism includes a locking structure joined to the base by a hinge. The locking structure spans both clamping elements. A spring biases the locking structure toward the channel so that the spring force is transmitted to the two clamping elements. The spring biased locking mechanism accommodates wear of the device, accommodates thermal expansion of the motor components, provides a limit on clamping force and provides a zero power hold condition.
