AIR DATA PROBE WITH IMPROVED PERFORMANCE WHEN OPERATING AT A HIGH ANGLE OF ATTACK

摘要

An air data probe (46) has a pitot tube with a tap (47) at a forward end (48) that defines an inner flow path. The inner flow path decreases in the cross-sectional area until reaching a throat (50). Bleed holes (52) or slots are provided to eliminate air recirculation and boundary layer separation. The outer surface of the tube may comprise a relatively flat portion and a bulged portion, or a long-nosed portion of smaller diameter and an enlarged portion.
