Aircraft feathering, flapping and rotor loads indicator
First Claim
1. A feathering, flapping and rotor loads indicator for use in a rotorcraft, the rotorcraft including at least one engine to power a rotor assembly including a mast and a plurality of blades attached thereto, the indicator comprising:
- a calculation unit configured to calculate (a) a temperature of a bearing of the rotor assembly using a first calculation model, and (b) a load exerted on a selected component of the rotor assembly using a second calculation model, the first and second calculation models adapted to calculate, respectively, the temperature of the bearing and the load exerted on the selected component based on flight control parameters; and
a display unit configured to dynamically display on a common scale a movable indicator, the movable indicator being driven by the highest value between the temperature of the bearing and the load exerted on the selected component.

Abstract
A feathering, flapping and rotor loads indicator for use in a rotorcraft includes a calculation unit configured to calculate (a) a current temperature 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 second calculation model, the first and second calculation models adapted to calculate, respectively, the projected and the current temperatures of the bearing and the load exerted on the selected component based on flight control parameters; and a display unit configured to display on a common scale a movable indicator, the movable indicator being driven by the highest value between the projected temperature of the bearing and the load exerted on the selected component. The display unit displays another movable indicator driven by the current temperature of the bearing.
