Prediiction of Incremental Aircraft Drag Due to Externally Carried Weapons

Abstract

The drag due to the external carriage of weapons on high speed attack aircraft results in large reduction in speed and range. An analytical method is being sought which will provide useful estimates of the drag increment caused by external weapon installation without the need for such tests. The method, based on regression techniques, utilizes the large amount of wind tunnel data obtained from previous tests. The prediction equation is determined as a function of the significant geometric parameters of the aircraft-store configuration. A highly encouraging degree of success has been achieved in application of the method to drag of stores mounted singly on pylons at Mach numbers of 0.8 and 0.9.
