Gaseous fluid flow i.e. air flow, speed measuring device for aircraft, has four flow measuring probes, where each probe comprises sensible element and obstacle masking determined measuring area of sensible element

摘要

The device has four flow measuring probes (1), where each probe comprises a sensible element (2) and an obstacle (3) masking a determined measuring area of the sensible element. The obstacle is constituted by masking elements for masking an angular sector of the flow measuring probes with respect to the sensible element of the probes, which are arranged on a circular generator line of a spherical envelope. An independent claim is also included for a method for measuring characteristics of direction and speed of gaseous fluid flow.
