METHOD AND DEVICE FOR DETERMINING RESULTANT PRESSURE FORCES ACTING UPON AIRCRAFT SURFACE Russian patent published in 1994 - IPC

FIELD: experimental aerogasdynamics. SUBSTANCE: method involves the steps of: measuring static pressure on portions with the same orientation of a mock-up surface within a portion, determining an average value of static pressure for each portion being measured, adding average values of static pressure of the portions of aircraft mock-up. Device for effecting the method has "m" units 10 for averaging static pressure included into each measurement channel. Each static-pressure averaging unit 4 is made in the form of collector 11 with K channels for coupling with intake openings and mounting seat 5 for static pressure sensor 5, cross-cestion of each coupling channel being equal along the whole length. EFFECT: enhanced accuracy in determining resultant vector of pressure force acting upon the surface of aircraft mock-up. 4 cl, 3 dwg
