THE ORIGIN AND DISTRIBUTION OF SUPERSONIC STORE INTERFERENCE FROM MEASUREMENT OF INDIVIDUAL FORCES ON SEVERAL WING-FUSELAGE-STORE CONFIGURATIONS Ⅱ.- SWEPT-WING HEAVY-BOMBER CONFIGURATION WITH LARGE STORE (NACELLE).LATERAL FORCES AND PITCHING MOMENTS;MACH NUMBER, 1.61

摘要

A supersonic wind-tunnel investigation of the origin and distribu¬tion of store interference has been performed in the Langley 4- by 4-foot supersonic pressure' tunnel at a Mach number of 1.6. Separate forces on a store, a fuselage, a swept wing, and a swept-wing—fuselage combination were measured. The store was separately sting-mounted on its own six-component internal balance and was traversed through a wide systematic range of spanwise, chordwise, and vertical positions. The configuration investigated simulated a heavy bomber airplane with a large store or nacelle having frontal area equivalent to a twin-engine nacelle.
