The distribution of pressure over the surface of airship model U.721, together with a comparison with the pressure over a spheroid

Abstract

Undertaken to obtain data upon which to base nose-stiffening calculations on new airship. Distribution of pressure was measured over the whole length of the airship model at zero angle of incidence, with wind speed varying from 30 to 75 ft/sec. Also the pressures were measured on the nose of the model at different angles of yaw and roll at a wind speed of 40 ft/sec. A cone tangential to the model at a point near the nose was added, and the pressures aft of the circle of contact measured.
