초록

An apparatus and method for measuring airflow past an aircraft by extending a probe (14) from the aircraft into the airflow with a retraction-extension mechanism (20) when a measurement is desired, and retracting the probe (14) when a measurement is not desired. In a low observable aircraft (12), the probe (14) can extend to measure angle of sideslip for flight in a slow speed regime, such as is experienced in vertical take-offs and landings, and can retract during normal wing borne flight to reduce the aircraft's radar signature.
