초록

A variable guide vane actuator for positioning the guide vanes of a turbine engine in a hypersonic missile uses compressor exhaust to drive a linked, floating piston assembly that is coupled to the guide vanes. The relatively low pressure compressor exhaust is metered by a valve to drive the piston arrangement to accurately position the guide vanes in proportion to the input control signal. Reliability and accuracy gains are achieved by inhibiting the effects of vibration and thermal distortion through the elimination of piston/bore contact, the use of a...

청구항

1. An actuator for positioning guide vanes of a turbine engine, the actuator comprising: a housing defining a bore;a piston slideably disposed in the bore, the piston having a head spaced from the housing bore and having a rod extending from the head;a metallic head seal mounted to the head to create a sliding seal against the housing bore;a metallic rod seal mounted to the housing to create a sliding seal against the rod; andan output member coupled to the piston;wherein the piston is disposed within the bore such that the piston position is independent...
