INTEGRATED FIRE AND FLIGHT CONTROL SYSTEM WITH AUTOMATIC ENGINE TORQUE LIMITING

An integrated fire and flight control (IFFC) system (10) senses the actual engine torque (126) of a rotary wing aircraft in successive real time intervals and compares the sensed interval values with one or more reference maximum torque limits (144) for each of one or more prescribed maximum time in...

More Information
Summary:An integrated fire and flight control (IFFC) system (10) senses the actual engine torque (126) of a rotary wing aircraft in successive real time intervals and compares the sensed interval values with one or more reference maximum torque limits (144) for each of one or more prescribed maximum time intervals and, in the presence of an above limit actual torque for an above limit prescribed time interval, the IFFC automatically reduces the collective axis command (54).
