Available in PDF, EPUB and Kindle. Book excerpt: The NOL hypervelocity wind tunnel will provide a high Reynolds number turbulent flow simulation in the Mach number range 10 to 20. This facility, much needed for large-scale testing of hypersonic vehicles, will be operational late in 1972. This report presents the detailed procedure used to design three nozzles for the facility. Pressure and temperature effects on the thermodynamic properties of nitrogen are taken into account in both the inviscid core and the boundary layer calculations. The supersonic portion of the inviscid core is calculated by the method of characteristics and the subsonic portion is approximated as a one-dimensional flow. The boundary layer calculation procedure is based on an integral moment of momentum equation and is valid for thick as well as thin boundary layers.

This book was released on 1971 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The equations used to calculate the boundary layer properties for use in the design of the Mach 10, 15, and 20 axisymmetric nozzles of the hypervelocity wind tunnel at NOL are derived. One equation is the integral moment-of-momentum differential equation for the boundary layer velocity profile shape parameter; the form of the equation is valid for a real gas. This equation is used with an axisymmetric integral momentum equation that is valid for thick as well as for thin boundary layers to calculate the total thickness and the displacement effect of the boundary layer.

Available in PDF, EPUB and Kindle. Book excerpt: The aerodynamic capabilities and physical characteristics of the Naval Ordnance Laboratory's Mach number 18 Hypervelocity Research Tunnel are described. This tunnel is a high-pressure, blowdown-type facility that uses nitrogen as the working gas. The facility provides a maximum test section Reynolds number of 0.2 million per meter (0.7 million per foot) at the maximum stagnation pressure of 700 atmospheres and a supply temperature of 2100 Kelvin. A forced-convection electric heater with a graphite heater element is used to achieve the required flow temperatures. The axisymmetric, contoured nozzle is 3.96 meters long with an exit diameter of 0.61 meters. Flow times are from one to four minutes.

Download or read book NOL Hyperballistics Tunnel No. 4 Results I: Air Liquefaction written by P. Wegener and published by . This book was released on 1951 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the presence of condensed air in a hypersonic wind tunnel can make the operation of the tunnel difficult, and since liquefaction can occur when the temperature and pressure in the test section are below the condensation values, an investigation was carried out on the liquefaction of air in a hypersonic wind tunnel. The tunnel used was built to operate at Mach numbers up to 11. The liquefaction was investigated under conditions in which the temperature and pressure of the supply air could be varied. It was found that air, unlike water vapor, does not supersaturate and heating of the supply air is required for satisfactory operation of a hypersonic wind tunnel. Experimental measurements show that a portion of the air condenses at or shortly after it reaches the predicted conditions for equilibrium-saturation in the nozzle. Since the presence of liquefaction may affect standard methods of measuring the Mach number of the flow in the tunnel, the response of these standard methods to liquefaction was examined. It was found that pitot-tube determinations of Mach number are relatively insensitive to air liquefaction whereas determinations using static pressures and shock-wave angles that are produced by slender bodies vary with the amount of air condensation. By maintaining a high temperature in the supply air the various standard methods for measuring the Mach number were found to give consistent Mach number data.

Book excerpt: This report describes a continuous hypersonic wind tunnel which was put into operation at the U.S. Naval Ordnance Laboratory in 1963. The tunnel uses nitrogen which is heated to 5000 R by a graphite resistance heater. The Mach number capability is from 12 to 18 with test section Reynolds numbers from 2.6 x 10,000 to 7 x 100,000 per foot. Operations so far have been restricted to the neighborhood of Mach 17.5 and 100,000 per foot in Reynolds number. The report describes the design and operation of the wind tunnel and gives some of the initial experimental results. (Author).
