Book excerpt: Summary: Methods are described for estimating pressure distributions over protuberances such as cockpit canopies, gun turrets, blisters, scoops, and sighting domes. These methods are applied to the estimation of the pressure distributions over spherical-segment and faired gun turrets and over the protuberances on the Brewster SB2A-1 airplane. The effects of compressibility, interference, and flow separation are discussed. It is shown that, by a combination of experimental data with theoretical methods, limiting pressures for use in determining maximum loads can in many cases be satisfactorily estimated. Much systematic experimentation is needed, however, to improve the accuracy of estimation.
