The Model 9790-BVR Scorsby Motion Test Table is designed to simulate 3 motions of
flight: roll, pitch, and yaw. Originally designed for shop, production, qualification
testing, and exercising of gyroscopic aircraft instruments, the Scorsby table became
a standard in the aircraft industry. Currently, the Scorsby table is used for testing
inertial sensors including gyroscopic components and motion-sensing systems in a
wide variety of industries.
The Model 9790-BVR is the heavy-duty stand alone version of the 1421 Series Scorsby
Table with up to a 500 pound payload capacity. The Scorsby table can be operated
through the front panel controls or the remote communications interface. The front
panel consists of a power switch, LCD display, and four keys: run/menu, increase,
decrease, and enter. Full computer-controlled automation can be accomplished with
an RS-232 (standard) or IEEE-488 (optional) interface.
The closed-loop motion control system consists of a DC motor, a digital microprocessor-based
controller, an optical encoder and a series of cogged belts to provide the required
gear reduction. The encoder is located on the shaft of the motor to provide high-resolution
feedback for smooth, stable Scorsby motion with a constant frequency.
The pitch, roll and yaw motions are achieved with a single rotating shaft and Ideal
Aerosmith's patented head design. The sinusoidal motion of each of the axes is related
to the shaft motion and can not be controlled independently.
