Book Description
A free-flight investigation of a rocket-propelled model at Mach numbers of 0.7 to 1.53 was conducted to determine the drag at zero lift of a configuration with a large fuselage cavity and partially submerged store. The basic configuration consisted of a 52.5 degree sweptback-wing-body configuration that had a smooth distribution of normal cross-sectional area at a Mach number of 1.0. The store was a parabola of revolution with a fineness ratio of 8, had three fins, and had a length equal to 40 percent of the fuselage length. The midpoint of the store was located longitudinally at a station corresponding to the 10-percent station of the wing mean aerodynamic chord. The cavity was designed from an impression of the submerged part of the store and was made smooth with fairings and rounded edges.

Book Description
Free-flight rocket-propelled model tests have been made to determine the effect of some wing geometry variables on low lift drag at Mach numbers from approximately 0.6 to 2.1. The pertinent results relate to 4- to 7-percent-thick 45 degree sweptback wings. At supersonic speeds, the wing drag was higher with the NACA 2-006 airfoil sections than with the NACA 65A006 airfoil sections particularly at the higher test Mach numbers where it was over 40 percent higher. Drooping the forward 20 percent of the wing 6 degrees increased the wing drag coefficient as much as 30 percent at supersonic speeds. Moving the wing vertically from the fuselage center line to the top of the fuselage increased the configuration drag substantially at supersonic speeds.
