A semi-flush air data sensing probe is formed as an elongated bubble housing directly supported on an aircraft surface having a generally longitudinally extending rounded outer edge surface with a rounded contoured leading end. The housing has top and bottom wall surfaces extending from the supporting surface to the rounded outer surface. The trailing end of the housing is smaller than the leading end and is contoured to provide for smooth airflow past the housing. A central longitudinally extending plane that bisects the housing and which is perpendicular to the supporting surface, forms a reference. A forwardly facing port is at the leading end and centered on the central plane, and a pair of angle of attack sensing ports are on the leading end and are symmetrically located on opposite sides of the longitudinally extending plane. A static pressure sensing port also is provided on the housing at a position along the rounded outer edge surface and spaced downstream from the leading end.
A semi-flush air data sensing probe comprising a probe housing having walls forming a bubble protruding from a support surface, said housing having a leading end surface that is rounded in three dimensions and having a rounded outer edge surface spaced from support surface extending in fore and aft direction from a leading end to a trailing end, the rounded outer edge surface joining top and bottom wall surfaces that diverge from the rounded outer edge surface and extend back t the support surface, the rounded outer surface being smoothly tapered toward the support surface from the maximum dimension toward a trailing end, the housing having a bisecting plane extending along a fore and aft central axis and perpendicular to the support surface, and at least one pressure sensing port on the housing.
A semi-flush air data sensing probe comprising a housing having a formed wall extending from a support surface into an air flow, said housing having a leading end surface that is rounded in three dimensions and having a rounded outer edge surface spaced laterally from the support surface and extending in fore and aft direction from a leading end to a trailing end, the rounded outer edge joining top and bottom wall surfaces of the housing that diverge from the rounded outer edge surfaces and extend back to the support surface, the rounded outer surface tapering from a maximum laterally extension toward a trailing end of the housing, the housing having a bisecting plane extending along a fore and aft central axis and perpendicular to the support surface, and at least a pair of pressure sensing ports positioned on the leading end on opposite sides of the bisecting plane and facing upstream relative to airflow and outwardly to the bisecting plane thereby having differential pressure sensed between the ports of the pair of ports when the bisecting plane is at an angle relative to airflow past the semi-flush probe.
