A new procedure unifying the best of present classical design practices, CFD and optimization procedures, is demonstrated for designing the aerodynamic lines of hypersonic wind tunnel nozzles. This procedure can be employed to design hypersonic wind tunnel nozzles with thick boundary layers where the classical design procedure has been.

    Models of increasing complexity have been developed for the design and simulation of the axisymmetric inviscid fluid mechanics and energy addition of an electron-beam driven hypersonic wind tunnel for missile-scale testing and development. The principal target has been a Mach capability at altitudes of approximately 25 km and above with a test section of m. Hypersonic Wind Tunnel Calibration Using the Modern Design of Experiments A calibration of a hypersonic wind tunnel has been conducted using formal experiment design techniques and response surface modeling. Data from a compact, highly efficient experiment was used to create a regression model of the pitot pressure as a function of the facility operating conditions as well as the .

Summary of design techniques for axisymmetric hypersonic wind tunnels. [Paris] North Atlantic Treaty Organization, Advisory Group for Aeronautical Research and Development, (OCoLC) The paper involves a design of Mach 5 Nozzle from an existing Mach 6 Nozzle of a large Hypersonic Wind Tunnel in Vikram Sarabhai Space Centre, Thiruvananthapuram in order to obtain the simulation of Mach 5.

The work deals with design of nozzle contour using specific boundary conditions, where by changing minimum numbers of existing nozzle components. A new procedure to design the contour of an axisymmetric hypersonic wind tunnel nozzle is presented. The method may be generally categorized as Navier-Stokes-based design by analysis.

Second, the starting behavior of hypersonic air intakes was investigated experimentally in a blow down wind tunnel with a three-dimensional intake model with planar surfaces.

SIVELLS; 3rd Flight Test, Simulation, and Support Conference August   In the design of hypersonic wind tunnel nozzles or air intakes, often times the boundary layer displacement is considered, as it additionally contracts the flow. In this manuscript, however, we did not consider viscosity during the design, as the investigated Mach numbers are well below the hypersonic range.

' A computer program is presented for the aerodynamic design of axisymmetric and planar nozzles for supersonic and hypersonic wind tunnels. The program is the culmination of the effort expended at various times over a number of years to develop a method of de- signing a wind tunnel with an inviscid contour which has contin.

Abstract. A method for design of hypersonic nozzles for wind tunnels is developed and implemented on the basis of solving direct problems with various models of the medium and numerical methods of integration of gas-flow equations.

A moveable block planar nozzle wind tunnel design from the University of Michigan in was shown with previous analysis to operate between Mach 1 and at least Mach for mid-size test sections, with continuous variation in Mach number and accounting for limitations governed by supply temperature and pressure, liquefaction, flow rate, and flow quality for a desired dynamic pressure or.

A new procedure unifying the best of present classical design practices, CFD and optimization procedures, is demonstrated for designing the aerodynamic lines of hypersonic wind tunnel nozzles. Supersonic and hypersonic wind tunnel nozzles are classified into several types based on the necessary area ratio A/A ∗.

The most useful and common type of nozzle is axisymmetric one with circular cross section at every station. Therefore, in sub-scale HAT facility modification process supersonic axisymmetric nozzles are preferred.

A hypersonic wind tunnel is designed to generate a hypersonic flow field in the working section, thus simulating the typical flow features of this flow regime - including compression shocks and pronounced boundary layer effects, entropy layer and viscous interaction zones and most importantly high total temperatures of the flow.
