Abstract
A system for airspeed estimation utilizing propulsor data in electric vertical takeoff and landing (eVTOL) aircraft is provided. The system generally comprises at least a propulsor, at least one sensor and a flight controller. The at least a propulsor is mechanically coupled to a body of an eVTOL aircraft, wherein the at least a propulsor is configured to propel the eVTOL aircraft. The at least one sensor is configured to detect a torque of the at least a propulsor, and transmit the torque of the at least a propulsor. The flight controller is configured to receive the torque of the at least a propulsor and determine an airspeed of the eVTOL aircraft as a function of the torque of the at least a propulsor. A method for airspeed estimation utilizing propulsor data in electric vertical takeoff and landing (eVTOL) aircraft is also provided.
