Development of an Extended Duration 1200 Deg F Torque Motor

Abstract

The application of high performance fluid power servos for attitude and engine control functions to advanced flight vehicles necessitates advancing the state-of-the-art of hydraulic systems in regard to their sensitivity to environmental conditions. In order to achieve this objective, the Air Force has sponsored the design and development of a 1000 deg F hydraulic system. This paper reviews the development and evaluation of an extended duration 1200 deg F torque motor representing the first component developed specifically for this system. Emphasis in the paper is placed on the approach to material selection, motor design, and the test results obtained.
