Force and moment data were botained with a 0.05-scale model of the F-4D aircraft at Mach numbers from 0.75 to l.30 to determine the effects of different store and rack configurations on the static stability and drag of the aircraft. Six proposed rack launchers and four proposed store shapes were tested for a total of 57 external loading configurations. (Author).
Longitudinal aerodynamic characteristics of 0.05-scale models of A-7D and F-4E aircraft were obtained at Mach numbers from 0.50 to 1.30 to determine the effects of store configuration and location on stability and drag. Prototypes, as well as a family of proposed store configurations, were tested. (Author).
An investigation was made at high subsonic speeds of a complete model having a highly tapered wing and several tail configurations. The basic aspect-ratio-4.00 wing had a zero taper and an unswept 0.80 chord line. Several aspect-ratio modifications to the basic wing were made by clipping off portions of the wing tips. The complete model was tested with a chord-plane tail, a T-tail, and a biplane tail (combined T-tail and chord-plane tail). The model was tested in the Langley high-speed 7- by 10-foot tunnel at Mach numbers from 0.60 to 0.92. The data show that, when reduced to the same static margin, all the tail configurations tested on the model provided fairly good stability characteristics, the biplane tail giving the best overall characteristics as regards pitching-moment linearity. Changes in static margin at zero lift coefficient with Mach number were small for the model with these tails over the Mach number range investigated.
