A series of wind tunnel studies were accomplished at the USAFA to determine the effect of a new low side area pylon on the static longitudinal stability of aircraft carrying external stores. Several configurations of MK 82 and M 117 bombs on triple ejection racks and multiple ejection racks were run at Mach numbers of .2, .82 and .91. The static margins for similar bomb configurations on inventory type pylons and new low side area pylons are compared. For the tests at M .2 the loss in static margin for a given configuration on the new low side area pylon was an average of 19 less than that on an inventory type pylon. The average loss in static margin for the transonic runs with the inventory pylon was 8.9 mean aerodynamic chord MAC while the same configurations with the new pylon gained an average of 2.2 mean aerodynamic chord MAC.
