The speed (54, 56) of the free turbine (40) of a helicopter engine (20) is compared (103) with the speed (105, 106) of the helicopter rotor (10) to indicate (101, 102) autorotation, and the deceleration (108) of the rotor above a threshold magnitude (110) is utilized (81, 68, 69) to increase fuel flow (72) to the engine in anticipation of rotor speed droop which would otherwise occur during recovery from the autorotation maneuver.


A helicopter, comprising: a rotor; an engine; rotor drive means including an overrunning clutch for connecting said rotor to said engine whenever the speed of said rotor does not exceed the speed of said engine; and engine control means for providing an engine speed signal indicative of the rotary speed of said engine, for providing a fuel command signal indicative of fuel flow required for desired engine operation, and for metering fuel flow to said engine in response to said fuel command signal; characterized by: rotor speed means for providing a rotor...
