Aircraft Digital Input Controlled Hydraulic Actuation and Control System.
Abstract
This document reports the development of an incremental digitally-controlled electrohydraulic actuation system (DEHA). An electronic digital controller and a prototype DEHA unit, with an electric-stepper-motor-driven rotary distributor valve, two hydraulic drive motors, and a torque-summing gearbox, were assembled. Significant reductions in the hydraulic power normally required with a conventional geared hydraulic motor system, and some degree of hydraulic power recovery were obtained. (Author)
