Paper Abstract

Specifications for future airborne tactical electro-optical systems often call for very large, unobstructed horizontal scan angles. This requirement poses unique challenges for the mechanical design of the gimbal system. This paper describes the design and testing of a two- axis gimbal which incorporates a modular sector bearing system, a limited-angle direct-drive torque motor, and a lightweight, high-accuracy position transducer to provide an unobstructed optical aperture of more than five inches through a horizontal scan angle of +/- 90 degree(s), while allowing more than +/- 50 degree(s) of elevation travel.
