AIRCRAFT FEATHERING, FLAPPING AND ROTOR LOADS INDICATOR

摘要

A feathering, flapping and rotor loads indicator for use in a rotorcraft includes a calculation unit configured to calculate (a) a current temperatur e of a bearing of the rotor assembly using a first calculation model, (b) a projected temperature of the bearing using the first calculation model and ( c) a load exerted on a selected component of the rotor assembly using a seco nd calculation model, the first and second calculation models adapted to cal culate, respectively, the projected and the current temperatures of the bear ing and the load exerted on the selected component based on flight control p arameters; and a display unit configured to display on a common scale a mova ble indicator, the movable indicator being driven by the highest value betwe en the projected temperature of the bearing and the load exerted on the sele cted component. The display unit displays another movable indicator driven b y the current temperature of the bearing.
