1. 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 first measurement associated with a vehicle state associated with an aerodynamic actuator, determine a set of rotor operating parameters based on an electronic control signal associated with an aerodynamic actuator, calculate a first value of an airflow parameter using a model relating a power coefficient of the aerodynamic actuator to an airflow parameter, and to determine the vehicle state parameter of the of the aircraft based on the first measurement and the first value.
