Flight Verification of Direct Digital Drive for an Advanced Flight Control Actuation System (AFCAS) in the T-2C Aircraft.

Abstract

The feasibility of Direct Digital Drive for an Advanced Flight Control Actuation System (AFCAS) was successfully demonstrated in a T-2C aircraft. The test installation contained a digitally-controlled direct-drive rudder actuator, microcomputer, electronic drive unit, force transducers, and a localized 8000 PSI (55 MPa) hydraulic power supply. The system met all laboratory and flight test objectives and demonstrated direct microcomputer control of primary flight control surfaces. This program has demonstrated an approach that will improve performance and reliability of fly-by-wire control systems by reducing the system complexity. (Author)
