Introduction

In order to meet the requirement for developing hypersonic vehicles, advanced hypersonic test facilities have been developed over the world for decades. Several types of facilities were developed to produce hypersonic flows, including the combustion-heated wind tunnels, the arc-heated hypersonic wind tunnels, conventional air-heated wind tunnels, heated-light-gas driven shock tunnels, free-piston driven high-enthalpy shock tunnels, and detonation-driven shock tunnels[1]. To clarify the real gas effect of hypersonic flows and the effect of test-gas contamination on supersonic combustion, the shock tunnel appears to be promising test facilities to provide hypersonic tests with pure air flows of hyper-velocity and high total temperature. However, the test-duration produced by shock tunnels is usually quite short for supersonic combustion and the large scale models of hypersonic vehicles, therefore, it becomes very difficult for hypersonic propulsion tests with hydro-carbon fuels. A research project to investigate some techniques for developing long-test duration and hype-velocity shock tunnels has been launched since 2002 in the State Key Laboratory of High-temperature Gas Dynamics, Institute of Mechanics, Chinese Academy of Sciences[2]. Research progresses has been achieved recently with numerical simulations and experiments in several aspects, and some results are summarized and reported in the paper.
