An apparatus senses a free stream flow parameter using airflow adjacent an air vehicle. The apparatus includes a first sensor sensing a longitudinal axial component and a lateral axial component of a parameter of local airflow immediately adjacent the first sensor. A second sensor senses a longitudinal axial component and a second axial component perpendicular to the lateral axial component sensed by the first sensor of a parameter of local airflow immediately adjacent the second sensor. The first and second sensors are mounted on the air vehicle such th...
An apparatus for sensing a parameter of free stream airflow using airflow adjacent an air vehicle, the apparatus comprising: first sensor means for sensing a longitudinal axial component and a lateral axial component of a parameter of a first local airflow immediately adjacent the first sensor means, the first local airflow being different than the free stream airflow, the first sensor means providing output signals as a function of the local longitudinal and lateral components, the first sensor means being mounted on the air vehicle such that a longitud...
