Abstract:
A system for regulating the output of at least one engine of a helicopter, said regulating system being able to automatically meter the fuel fed to said engine and comprising:at least one metering valve for metering said fuel fed to the engine, as a function of control commands; a first means for measuring an NTL output corresponding to the rotational output of the free turbine of said engine; a second means for measuring an NG output corresponding to the output of the gas generator of said engine; a device for determining a pre-set value NTLcons corresponding to the pre-set value of the rotational output of the free turbine of the engine; and computation means for automatically computing the control commands which are applied to said metering valve, said computation means computing control commands making it possible to slave, knowing said measured NG output, the output of the gas generator of said engine to a pre-set value NGcons of said output of the gas generator, which depends on said measured NTL output and on said specified pre-set value NTLcons, wherein said device comprises at least:a third means for determining the position (D&dgr;) of a rudder bar of said helicopter; and an auxiliary computation means which computes said pre-set value NTLcons as a function of said position (D&dgr;) of the rudder bar.
