The Model 1411E and 1412E Scorsby Motion Test Tables are designed to simulate the
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 Scorsby table has a synchronous AC motor with a gear train that provides smooth
Scorsby motion at a constant frequency. The 1412E series is identical to the 1411E
series except for the addition of a larger flywheel coupled to the shaft of the
drive motor to dampen speed changes. This addition provides a uniform, constant
acceleration and deceleration of the table top at the start, stop, or auto-reverse
of each cycle. This feature is desirable for sensitive instruments that require
a slower acceleration/deceleration or zero dwell time between auto-reverse cycles.
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.
