Investigation at a Mach Number of 1.93 to Determine Lift, Drag, Pitching-Moment, and Average Downwash Characteristics for Several Missile Configurations Having Rectangular Wings and Tails of Various Spans (open access)

Investigation at a Mach Number of 1.93 to Determine Lift, Drag, Pitching-Moment, and Average Downwash Characteristics for Several Missile Configurations Having Rectangular Wings and Tails of Various Spans

Memorandum presenting an investigation made at a Mach number of 1.93 to determine lift, drag, pitching-moment, and average downwash characteristics of several missile configurations. Five configurations with rectangular wings and tails of various spans were tested; each of the configurations had two locations of the wing relative to the tail.

Some considerations of the influence of body cross-sectional shape on the lifting efficiency of wing-body combinations at supersonic speeds (open access)

Some considerations of the influence of body cross-sectional shape on the lifting efficiency of wing-body combinations at supersonic speeds

From Summary: "Linearized theory is used to estimate the order of magnitude of the beneficial effects that can be obtained by shaping the body of a wing-body configuration to generate lift indirectly at supersonic speeds. The analysis applies to a class of wing-body configurations which is believed to exhibit the essential features of this type of interference; the body is cylindrical upstream of a wing which has supersonic edges and the parts of the body above and below the wing are each semicircular and of different radii. Calculations are presented for a Mach number of the square root of 2 for a particular family of bodies and a sonic-edge delta wing."

Effect of Camber on the Drag of a Body of Revolution (open access)

Effect of Camber on the Drag of a Body of Revolution

Memorandum presenting an investigation to determine the effect of camber on the drag of a body of revolution. The drag of a straight body of revolution was measured and compared with that of a body that differed only in that its center line was cambered in the form of a parabola. The addition of a small amount of camber was found to cause very little increase in the minimum foredrag of the model tested.

Effect of Blade-Section Camber on Aerodynamic Characteristics of Full-Scale Supersonic-Type Propellers at Mach Numbers to 1.04 (open access)

Effect of Blade-Section Camber on Aerodynamic Characteristics of Full-Scale Supersonic-Type Propellers at Mach Numbers to 1.04

Report presenting an investigation of the aerodynamic characteristics of two full-scale supersonic propellers with a 6000-horsepower propeller dynamometer. One propeller had symmetrical NACA 16-series airfoil sections and the other was similar except for a blade-section camber and a slight difference in pitch distribution.

Theoretical Investigation of a Proportional-Plus-Flicker Automatic Pilot (open access)

Theoretical Investigation of a Proportional-Plus-Flicker Automatic Pilot

"The proportional-plus-flicker automatic pilot operates by a nonlinear principle whereby a fast-acting flicker servomotor response is combined with a low-speed proportional servomotor response for the purpose of obtaining supersonic stability and control. Essentially, the autopilot maintains a zero reference about which the output is proportional to the input. However, a flicker response overrides this proportional response at a fixed angle of gimbal displacement on either side of the zero gyroscope reference" (p. 1).
