FURTHER DEVELOPMENT OF CAPACITANCE-AND INDUCTANCE-DRIVEN HOTSHOT TUNNELS

Abstract

An arc chamber with coaxial electrodes was developed for the inductance-driven 50-Inch Hypervelocity Tunnel (Hotshot 2). Combined with a short-circuit switch, to reduce the discharge time, this configuration resulted in a significant decrease in flow contamination ion Force tests in Mach number range from 16-22 at stagnation temperatures from 3000-4000 K and stagnation pressures from 10,000-20,000 psi were in good agreement with results from other tunnels. An arc-chamber liner material study was carried out in the capacitance-driven Tunnel Hotshot 1. The materials tested included copper, boron nitride, graphite, tungsten, and chrome-plated copper. The heat losses through the arc-chamber walls of Hotshot 1, determined from runs at stagnation temperatures from 3000-9000 K, are presented, and their implications on hotshot tunnel operation are discussed.
