GAS-TURBINE ENGINE REMOTE CONTROL SYSTEM Russian patent published in 2005 - IPC

FIELD: shipbuilding; main propulsion engines.

SUBSTANCE: proposed remote control system of gas-turbine engine contains setting member connected with actuating mechanism mechanically coupled with feedback sensor. Setting member is connected by summers and amplifiers with actuating mechanism mechanically coupled with cam mechanism furnished with limit switches. At least between one of summers and amplifier AND logic gate is series connected whose inputs and connected with limit switches, and also multivibrator. Cam mechanism is provided with shaft mechanically coupled with actuating mechanism and provided with freely fitted-on cams engaging with limit switches and separating washers fixed on shaft and arranged along axis of shaft between cams. Shaft is provided with longitudinal slot accommodating stepped key with cavities in place of arrangement of cams on shaft, and projections in place of arrangement of separating washers on shaft. Shaft is furnished with nut interacting through pressure spring with separating washers and cams.

EFFECT: improved reliability of remote control system of gas-turbine engine.
