Report presenting a new blade series designed to operate at near choking inlet Mach numbers and to have near maximum critical Mach numbers by employing high aerodynamic loading of the profiles in the leading-edge region and relatively straight trailing edges. Results regarding the aerodynamic characteristics and prediction of high-speed performance are provided.

"A free-flight investigation into the effect of fuselage gloves, or load increases in volume, designed to improve the overall longitudinal area distribution of a swept-wing-body combination revealed that a reduction of about 20 percent in maximum pressure drag was obtained. The drag reduction effected by the use of gloves decreased with increasing Mach number, becoming zero at a Mach number of about 1.35, the limit of the experiments" (p. 1).

Report presenting an investigation of the aerodynamic characteristics of a model of the NACA RM-10 in the hypersonic tunnel at a Mach number of 6.9. Longitudinal pressure surveys were made on the body without fins at zero lift and at angles of attack. Results regarding the pressure distributions, forebody pressure forces, body forces, fin-body combination forces, pitching moment and center of pressure, variation of the zero-lift drag components with Reynolds number and Mach number, variation of the lift-curve slope and center of pressure with Mach number, and Schileren observations are provided.

Memorandum presenting low-lift drag and longitudinal trim data for two versions of an interceptor-type airplane, the second of which had a slimmer nose and a thinner tail than the first. Data are presented for three models (complete, wingless, and horizontal tailless) of the first version, and from one model (complete configuration) of the second version. Results regarding longitudinal trim, drag, longitudinal stability, and flutter and buffet are provided.
