Abstract:

Due to the strategic importance of near space in modern warfare, near space hypersonic vehicles represent a country's military capacity and has become a research focus for the field of aeronautics and astronotics. Pre-cooling technology has become a key technology for the propulsion system of air-breathing hypersonic near space vehicles with high flight altitude and mach number, and advanced heat exchangers are critical components of the pre-cooling system for hypersonic near space vehicle. The reliability as well as the heat transfer and pressure loss performance of the pre-cooler are all important influencing parameters of the pre-cooling system. The research on advanced heat exchangers of high reliability and heat transfer performance is of great significance for the propulsion system of near space vehicles. Based on the published data of major driving force of the near space hypersonic flight vehicle and the rigid demand of the flight for cooling technology, the key technology and future development orientation for the pre-cooler used in hypersonic near space vehicles has been discussed.

Key words: near space, hypersonic flight vehicle, propulsion system, turbine-based combined cycle (TBCC), pre-cooler
