Book Description

This report and user's guide presents a computerized version of the wing-mounted single store airloads prediction methodology found in External Store Airloads Prediction Technique (Reference 1). The prediction technique reported in Reference 1 is somewhat time-consuming and tedious to use in its present form due to the multitude of manual computations required to complete a full six-component airloads solution. The computer routine developed during the current program and reported herein will eliminate most of the engineering effort required to evaluate captive store aerodynamic loads not only for current production aircraft-store configurations but also for new aircraft-weapons designs without resorting to expensive wind tunnel or flight tests. The technique should prove especially valuable for evaluation of new aircraft-weapons design in the preliminary design stages because of the rapid response now available using the computer program for chord-wise, spanwise, and vertical variations in store location. Therefore, it permits trade studies to be conducted to minimize installed loads, for example, or to determine a location where the captive loads promote favorable separation.
