The Model 9790-BVR Scorsby Motion Test Table from Ideal Aerosmith is designed to simulate the three 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 cannot be controlled independently.
