Abstract: A fuel management system (34) for a turbine engine (10) having a metering valve (50) controlled by the input of an electronic computer (36) to a resolver (48). A head sensor (64) responds to pressure differential across the metering valve (50), to control a bypass valve (80) which allows a portion of the fuel available from a supply conduit (58) to return to a reservoir (28). An overspeed governor (116) receives an input turbine (10) to position a cam (120) having four contours (154, 156, 158, and 160) thereon. The first contour (154) provides a feedback to balance the actual speed input. The second contour (156) controls the opening of a proportional valve (122) when the rotation of the turbine exceeds a preset value to allow an operational fluid pressure in the bypass valve (80) to be reduced and additional fuel to flow to the return conduit (95).
