This book was released on 1972 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: BOMB RACKS, CONFIGURATIONStudies were made of experimental data to determine the effects of various external store characteristics, spanwise positions, and Mach number on the static longitudinal stability of various aircraft. Data used included results of wind tunnel tests run at the USAF Academy as well as tests run at the Arnold Engineering Development Center, the Naval Ship Research and Development Center and Breguet Aviation. External store characteristics considered were store frontal area, volume, and side projected area. The correlation between any of the three characteristics and change in static margin was approximately the same. Loss in static margin tended to increase to a maximum at moderate values of frontal area, volume, or side projected area and then to decrease for higher values. (Author).
