Book excerpt: The results from analysis of data obtained from wind tunnel tests, which were conducted to determine the effect of various external stores on the aerodynamic characteristics of the model F-4C airplane, are presented and discussed. The analysis includes evaluation of the static longitudinal stability, drag, and longitudinal control characteristics of the F-4C when loaded with the Pavestorm missile series, Modular Weapons series, Mark 84 EOGB, M-118 LGB, SUU-51B/B, SUU-30H/B, and Rockeye stores. Moreover, analysis of the probable cause as well as the wind tunnel verification of a pilot-reported 'tuck-under' problem with the F-4C when carrying the Pavestorm series of stores is presented and discussed. Incremental drag rise and neutral point shift associated with store loading are compared with results obtained from existing prediction methods and techniques. Data are presented for aircraft weights representative of each store loading at altitudes of sea level, 10-, 20-, and 30-thousand feet for aircraft center-of-gravity locations of 25, 33, and 36 percent of the mean aerodynamic chord over the Mach number range from 0.4 to 1.3.
