Helicopter cruise fuel conserving engine control

Patent ·
OSTI ID:5866381
; ;
A digital fuel control for a helicopter engine controls fuel flow to the engine in response to a turbine reference speed determined in a normal mode to be rated speed, in fade-in mode to be incremented to an estimated optimum minimum speed, in an optimizer mode to be incremented in a direction leading to least fuel consumption, and in a fade-out mode to be incremented bach to rated speed. The invention provides an engine reference speed which results in minimum fuel consumption during cruise flight.
