Control-by-Wire Actuator Model Development for AFCAS.
Abstract
The report describes the design and fabrication of an engineering model, 8000 psi, control-by-wire, modular configured, aircraft type hydraulic servo actuator for the Navy sponsored AFCAS development program. The modular elements could be used to build up either a dual tandem, dual parallel, or simple servo actuator. The tandem and parallel configurations were controlled by two synchronized, single stage, spool/sleeve type flow control valves designed to operate at 8000 psi using MIL-H-83282 fluid. Each valve spool was coupled directly to and driven by a force motor with rare earth cobalt samarium permanent magnets and four armature coils for redundancy. A dual parallel linear variable differential transfer position feedback transducer was mounted inside the acutator piston rod. Steady-state performance tests were conducted on one spool/sleeve assembly and force motor. (Author)
