Abstract
A method for determining airspeed of an aircraft that includes determining a rotor model relating a power coefficient of a propeller of the aircraft to an axial inflow velocity through the propeller as a function of a set of rotor operating parameters; determining the set of rotor operating parameters by sampling an electronic control signal associated with an electric motor actuating the propeller; computing the axial inflow velocity through the propeller based on the set of rotor operating parameters using the rotor model; and determining the airspeed based on the axial inflow velocity.
Claims7
An aircraft based system for determining airspeed, said system comprising:
- an aircraft;
- one or more rotor assemblies, the rotor assemblies comprising:
- a propeller;
- and
- an electric motor;
- a control system housed within the aircraft, the control system configured to determine a set of rotor operating parameters by sampling an electronic control signal associated with an electric motor actuating a propeller, compute the axial inflow velocity through the propeller based on the set of rotor operating parameters using a rotor model, and compute the airspeed based on the axial inflow velocity to generate a first determined airspeed.
