Pressure-Distribution Measurements on Various Surfaces of a 0.2375-Scale Model of the Douglas XA-26 Airplane in the 19-Foot Pressure Tunnel
Abstract
Pressure measurements were made on the spinner-cowl-nacelle assembly and fuselage of the XA-26 airplane for angles of yaw from -10degrees to 10 degrees and at angles of attack from -8 degrees to 8 degrees. Pressures were also measured on the bomb-bay, main-wheel, and nose-wheel doors at various angles from closed to full open. Results of pressure measurements on the doors are presented as loads and hinge moments, whereas measurements on the nacelle and fuselage are shown as pressures on isometric diagrams. Tests indicate that no critical pressures should be encountered in the high-speed level-flight condition of the airplane at 17,000 feet unless the spinner is removed.
