A differential pressure-induced airflow based approach is used to measure Angle-Of-Attack (AOA) or Angle-Of-Sideslip (AOS) for an aircraft. Ports on opposing sides of an aircraft fuselage are coupled by an airway incorporating a mass airflow sensor. As the relative wind's angle of incidence changes direction with respect to the aircraft's longitudinal axis or wing chord, a differential pressure is created. The differential pressure induces an airflow between the ports whose magnitude is measured by a mass airflow sensor. The resulting airflow is a functi...
1. An aircraft comprising:a first port positioned on a first side of the aircraft's fuselage;a second port positioned on a second side of the aircraft's fuselage;a pneumatic passage interconnecting the two ports; anda mass airflow sensor positioned in the passage interconnecting the ports. 2. The aircraft of claim 1 wherein the first and second ports comprise subassemblies mounted substantially flush with the aircraft, wherein the ports comprise one or more orifices. 3. The aircraft of claim 1 wherein the airflow sensor comprises a thin film mass airflow...
