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, spoolsleeve 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 spoolsleeve assembly and force motor. Author
