Abstract
A method of performing health monitoring for an aircraft having a variable pitch propeller system. The method includes: receiving aircraft flight information; performing a virtual pitch calculation to determine a virtual propeller pitch or virtual blade angle from the aircraft flight information; receiving a measured propeller pitch or blade angle from at least one physical sensor associated with the propeller; and using the virtual propeller pitch or virtual blade angle and the measured propeller pitch or blade angle to perform a health monitoring process to determine a health condition of at least one component of the aircraft, wherein the at least one component is distinct from the blades.
Claims16
A method of performing health monitoring for an aircraft having a variable pitch propeller system, the method comprising:
- receiving aircraft flight information;
- performing a virtual pitch calculation to determine a virtual propeller pitch or virtual blade angle from the aircraft flight information;
- receiving a measured propeller pitch or blade angle from at least one physical sensor associated with the propeller;
- and
- using the virtual propeller pitch or virtual blade angle and the measured propeller pitch or blade angle to perform a health monitoring process to determine a health condition of at least one component of the aircraft, wherein the at least one component is distinct from the blades.
A health monitoring system for a variable pitch propeller system of an aircraft, the health monitoring system comprising:
- a virtual pitch sensor configured to receive aircraft flight information and perform a virtual pitch calculation to determine a virtual propeller pitch or virtual blade angle from the aircraft flight information;
- at least one physical sensor configured to measure propeller pitch or blade angle;
- and
- a health monitoring processor configured to use the virtual propeller pitch or virtual blade angle and the measured propeller pitch or blade angle to perform a health monitoring process to determine a health condition of at least one component of the aircraft, wherein the at least one component is distinct from the blades.
