Transient Thermal Stresses in Pressure Vessels - Part I: Transient Temperature Distribution - Description of Computer Program

Description: This report describes an IBM 704 Computer program for the calculation of transient temperature distribution in axially symmetric solid or hollow bodies. It is the first part of Transient Thermal Stresses in Pressure Vessels. The present report mainly describes the use of the computer program and gives, for two problems, a comparison between computed and analytically known results. The analysis is reported briefly in this report.

Temperature measurements from a flight test of two wing-body combinations at 7 degree angle of attack for Mach numbers to 4.86 and Reynolds numbers to 19.2 X 10(exp 6)

Description: Report presenting a temperature survey for two bodies with wings swept 39 and 75 degrees for an angle of attack of 7 degrees, Mach numbers up to 4.86, and a designated Reynolds number. Effects of wing-body interference on heating and the difference in heating on windward and leeward sides at a designated angle of attack are explored. Pressure coefficients are also presented for two different stations on the body.

Effect of Frequency of Sideslipping Motion on the Lateral Stability Derivatives of a Typical Delta-Wing Airplane

Description: Report presenting an investigation to determine the effect of frequency of sideslipping motion on the lateral stability derivatives of a 60-degree delta-wing airplane configuration. Results regarding the steady-state tests, oscillation-in-sidestep tests, comparison of oscillation data for delta wings with a round edge versus a sharp edge, and effect of sideslip oscillatory derivatives are provided.

Effect of Ground Proximity on Aerodynamic Characteristics of Two Horizontal-Attitude Jet Vertical-Take-Off-and-Landing Airplane Models

Description: Memorandum presenting an investigation to study the effect of ground proximity on the aerodynamic characteristics of two jet vertical-take-off-and-landing airplane models in which the fuselage remains in a horizontal attitude for the take-off and landing. Results regarding the flow surveys and force tests are provided.

Effect of Conical and Flat Sting-Mounted Windshields on the Zero-Lift Drag of a Flare-Stabilized Bluff Body at Mach Numbers From 0.6 to 1.15

Description: Report presenting zero-lift drag data for a flare-stabilized bluff body of fineness ratio 4.4 alone and with conical and flat windshields at a range of Mach and Reynolds numbers. The model with the flat windshield was found to have the lowest drag at Mach numbers up to 1.05, but there was little difference in drag among the models above 1.05.

Investigation at Mach Numbers to 1.04 of Blade-Loading Characteristics of Two Full-Scale Three-Blade Supersonic Propellers Differing in Blade-Section Camber

Description: Memorandum presenting total-pressure surveys made in the slipstreams of two full-scale three-blade supersonic propellers in the 16-foot transonic tunnel at Mach numbers up to 1.04 to determine the effects of camber on supersonic-propeller characteristics. The two propellers were similar except that one of them had symmetrical blade sections and the other had cambered blade sections and a slightly different pitch distribution. Over the complete range of the tests, the cambered propeller maintain… more
