Some Effects of Aileron Deflection on the Static Lateral and Directional Aerodynamic Characteristics of Four Contemporary Airplane Models

Memorandum presenting some effects of aileron deflection on the static lateral and directional aerodynamic characteristics of four airplane models which are representative of aircraft capable of flight at supersonic speeds. The results are presented for subsonic Mach numbers ranging from 0.60 to 0.90 and for supersonic Mach numbers ranging from 1.20 to 1.90. They are limited to the most pertinent aerodynamic effects of ailerons contributing to the lateral and directional characteristics of each airplane type.

Aerodynamic Loads on Tails at High Angles of Attack and Sideslip (open access)

Aerodynamic Loads on Tails at High Angles of Attack and Sideslip

"Results are presented for the loads and moments acting on the individual tail surfaces of a body-tail combination over a wide range of angles of attack and sideslip. The effects of forebody length and panel-panel interference on the characteristics are included. It is shown that large nonlinear variations in these loads and moments, which occur at some combinations of angle of attack and sideslip, cannot be predicted by low-angle theory" (p. 1).

Experimental Investigation of Creep Bending and Buckling of Thin Circular Cylindrical Shells (open access)

Experimental Investigation of Creep Bending and Buckling of Thin Circular Cylindrical Shells

"Forty-three cylinders of 40-inch length and 16-inch diameter, made of 5052-0 aluminum-alloy sheets of 0.023-, 0.040-, 0.051-, and 0.064-inch thickness, were subjected to bending moments constant along the cylinder and in time in an oven which maintained a constant temperature of 500 degrees Fahrenheit during the test. All the cylinders failed by buckling. The time that elapsed between load application and collapse was measured" (p. 1).

Analysis of Wing Loads on a Flexible Swept-Wing Jet Bomber During Push-Pull Maneuvers (open access)

Analysis of Wing Loads on a Flexible Swept-Wing Jet Bomber During Push-Pull Maneuvers

Report presenting measurements of the loads of the wing of a Boeing B-47A medium bomber using strain-gage instrumentation during 23 symmetrical push-pull maneuvers at a variety of altitudes, Mach numbers, and gross weights. Time histories of aerodynamic shear, bending moment, and torque at each of four spanwise stations on the left wing and one on the right wing were created. Based on the results, presently available methods seem to be capable of predicting additional and basic loads accurately within the range of flight conditions in the test.

Investigation at Transonic Speeds of the Effects of Inlet-Lip Sweep on the Internal-Flow Characteristics of a Semielliptical Air Inlet With an Inlet-Lip Stagger of 30 Degrees (open access)

Investigation at Transonic Speeds of the Effects of Inlet-Lip Sweep on the Internal-Flow Characteristics of a Semielliptical Air Inlet With an Inlet-Lip Stagger of 30 Degrees

Report presenting an investigation in the transonic blowdown tunnel to determine the effects of inlet-lip sweep angle on the internal-flow characteristics of a semielliptical scoop-type inlet with an inlet lip stagger of 30 degrees. the testing was performed at a range of Mach numbers and mass-flow ratios. Results regarding flow over the nose, total-pressure recovery at inlet, flow distortions at inlet, boundary-layer control, and inlet performance are presented.
