Design of Shielded Pitot Tubes with Small Sensitivity to Incidence.

摘要

The range of incidence over which a pitot-tube accurately indicates stagnation pressure in subsonic flow can be substantially increased by surrounding the pitot with a carefully designed shield. In this Memorandum the effect of some of the design variables of this shield are investigated experimentally, and a miniature probe design is described which enables an accurate indication of stagnation pressure to be obtained over an incidence range of + or - 57 degree.
