ABLATION TESTING IN HOT AND COLD COAXIAL JETS. PHASE 1: COLD FLOW FEASIBILITY TESTS

Abstract

An investigation was conducted to determine the feasibility of extending the capability of ablation test facilities by surrounding the high enthalpy flow with a coaxial cold air jet. The investigation included both analytical and cold flow experimental studies. It was determined that the coaxial flow technique is extremely promising, offering the potential of easily doubling the facility model size capability. Results of the cold flow experimental tests and criteria for application of the technique to high enthalpy facilities are presented.
