Abstract

Direct-connect tunnels are an essential tool for advancing the technology of hypersonic air breathing propulsion systems. The feasibility of extending the capabilities of arc-jet wind tunnels into direct-connect facilities is being examined. Using published data on existing arc-jet tunnels and direct-connect facilities, a database containing the operating conditions of each facility has been generated including: flow energizing method, simulated flight Mach numbers, simulated dynamic pressure paths, enthalpy, operating temperatures, and operating pressures. With the support of this database, an applet is being developed that allows for the preliminary design of a planar 2-D scramjet combustor assuming the flow to be in thermo-chemical equilibrium and using pressure-length binary scaling to extract the general dimensions of the combustion chamber. Design information such as geometry, expected ignition time, expected reaction time, and total length are provided.
