  • Helicopter rotor icing detection system and method
    Patent number: 10479513
    Abstract: A system includes a signal monitor to monitor a time rate of change of a revolution per minute (RPM) trim signal that is received from an RPM command path to control a velocity of a helicopter rotor. An icing detector detects for the presence of ice accumulation on the helicopter rotor by comparing the time rate of change of the RPM trim signal to a predetermined threshold for the time rate of change.
    Type: Grant
    Filed: December 17, 2018
    Date of Patent: November 19, 2019
    Assignee: NORTHROP GRUMMAN SYSTEMS CORPORATION
