Abstract
Embodiments are directed to determining, by a computing device comprising a processor, at least one parameter associated with a rotorcraft, obtaining, by the computing device, a profile of a vibration associated with the operation of the rotorcraft based on the at least one parameter, determining, by the computing device, an amplitude of the vibration using the profile, and determining, by the computing device, an airspeed of the rotorcraft based on amplitude.
Claims18
A method comprising:
- determining, by a computing device comprising a processor, at least one parameter associated with a rotorcraft;
- obtaining, by the computing device, a profile of a vibration associated with operation of the rotorcraft based on the at least one parameter;
- determining, by the computing device, an amplitude of the vibration using the profile;
- and
- determining, by the computing device, an airspeed of the rotorcraft based on the amplitude.
