Linearized Supersonic Axially Symmetric Flow about Open-nosed Bodies Obtained by Use of Stream Function by Franklin Moore Pdf
First-order relations were obtained for attenuation of shock and flow deflection outward along the shock. These relations probably conform closely to physical fact, provided the entrance slope is small. These relations contain an error, but become exact as the radial coordinate approaches inifinity. The error is thus probably of the second order over the entire shock front.
The Aerodynamic Design of Supersonic Propellers from Structural Considerations by Jerome B. Hammack Pdf
The aerodynamic design of propellers from considerations of centrifugal force is presented. A solution is obtained for the span wise distribution of cross-sectional area required to attain constant centrifugal stress over most of the blade.
Wind-tunnel Investigation of Paraglider Models at Supersonic Speeds by Robert T. Taylor Pdf
An investigation was made in the Langley Unitary Plan wind tunnel to determine the behavior of paraglider models at moderate to high supersonic speeds. The models were deployed from a sting in the supersonic stream and steady-state aerodynamics performance data were obtained. Maximum values of the lift-drag ratio were about 1.4 at a Mach number of 2.65 and about 1.2 at a Mach number of 4.65. The angles of attack over which the models could be flown were limited by unsteady behavior of the canopy.
Ground Measurements of the Shock-wave Noise from Supersonic Bomber Airplanes in the Altitude Range from 30,000 to 50,000 Feet by Domenic J. Maglieri,Harvey H. Hubbard Pdf
Turbulent Shear Layers in Supersonic Flow by Alexander J. Smits,Jean-Paul Dussauge Pdf
A good understanding of turbulent compressible flows is essential to the design and operation of high-speed vehicles. Such flows occur, for example, in the external flow over the surfaces of supersonic aircraft, and in the internal flow through the engines. Our ability to predict the aerodynamic lift, drag, propulsion and maneuverability of high-speed vehicles is crucially dependent on our knowledge of turbulent shear layers, and our understanding of their behavior in the presence of shock waves and regions of changing pressure. Turbulent Shear Layers in Supersonic Flow provides a comprehensive introduction to the field, and helps provide a basis for future work in this area. Wherever possible we use the available experimental work, and the results from numerical simulations to illustrate and develop a physical understanding of turbulent compressible flows.
Investigation of the Aerodynamic Characteristics of a Supersonic Horizontal- Attitude VTOL Airplane Model at Mach Numbers of 1.57, 2.14, 2.54, and 2.87 by Arthur E. Franklin,Robert M. Lust Pdf
Public Health Aspects of Galactic Radiation Exposure in Supersonic Transport by Hermann J. Schaefer Pdf
The prospect of large-scale commercial passenger transportation at SST altitudes in the lower stratosphere calls for an accurate assessment of the galactic radiation exposure. Highest radiation levels prevail at high latitudes (polar region) and solar minimum and reach about 1 millirem/hour at 65,000 feet. The accumulated dose of 0.6 rem/year which an SST crew member spending 600 hours/year at altitude would receive exceeds the Maximum Permissible Dose (MPD) for 'Members of the Public' and would classify crew members as 'Radiation Workers' in terms of official recommendations. The assumption of 50 SST each exposing 200 passengers to 1000 hours/year at SST altitude would lead to a population dose about equal to the contribution from industrial radiation workers, with both exposures ranking well below the two largest man-made additions to the natural background, medical use of x-rays and fallout. The heavy flux is attenuated to 3 per cent or less at 65,000 feet, depending on the nuclear species; yet, only 0.1 per cent of this residual flux accounts for maximum ionization hits. That means the microbeam hazard of heavy nuclei is insignificant at SST altitudes. (Author).
