Theory of detonation-driven hypervelocity shock tunnels and its demonstration

The hypersonic ground testing is a critical issue for hypersonics. The problems arising from developing hypervelocity shock tunnels are identified and discussed in detail. The theory of detonation-driven hypervelocity shock tunnels is proposed for developing advanced ground facilities. The forward detonation cavity driver is developed to remove rarefaction wave effects for enhancing driving ability. The tailored condition for detonation-driven shock tunnels is also proposed to achieve long test duration.
