Abstract
An acoustic airspeed sensor system can include at least one acoustic transmitter configured to provide an acoustic pulse, a plurality of acoustic receivers including at least a first acoustic receiver positioned at a first radial distance from the at least one acoustic transmitter and a second acoustic receiver positioned at a second radial distance from the at least one acoustic transmitter. The first acoustic receiver is configured to receive the acoustic pulse at a first time and output a first receiver signal. The second acoustic receiver is configured to receive the acoustic pulse at a second time and output a second receiver signal. The sensor system can include an air data module operatively connected to the first acoustic receiver and the second acoustic receiver. The air data module is configured to determine true air speed (TAS) based upon a first signal delay, a second signal delay, and a wind angle.
