The results presented in this paper indicate that the effects of stores on wing load distribution at subsonic speeds may be predicted by available methods at the lower angles of attack where wing flow separation is negligible. At the higher angles of attack where wing flow separation exists, a store located inboard on a swept wing may act much like various devices designed to delay wing pitch-up by reducing the loss in load at the wing tip due to flow separation. Furthermore, the results indicate that the normal force and pitching moment of a store located at the wing tip can be calculated quite well by available methods. On the other hand, no theoretical procedure is available to calculate the severe lateral forces and moments encountered at zero sideslip on an inboard arrangement of stores on a swept wing.
