AN INVESTIGATION OF THE EFFECT OF RANDOM FUSELAGE WALL IRREGULARITIES ON FLUSH STATIC PRESSURK PORT CALIBRATIONS

摘要

An investigation of the effect of random surface irregularities in the vicinity of flush pressure ports on the sciatic pressure calibration characteristics of presumable identical aircraft is described. A method for analysis of wall irregularity effects is presented together with useful computation tables. Such irregularities were measured on thirteen B-47, eleven B-52, and eleven F-101 airplanes and the resulting pressure errors were computed and are computed and are summarized with the help of small sampling theory statistics.
