International Journal of Hypersonics
Multi-Science Publishing, May 2012
Research in the field of hypersonic flows extends from applications to space travel and to the production of low temperature flows to study the gas-phase processes relevant to interstellar chemistry in the laboratory. Interest in hypersonic research reached the peak in the early stages of space exploration and the development of intercontinental ballistic missiles. Many large size national test facilities were built in the technologically advanced countries to produce the design data for the hypersonic vehicle configurations while fundamental research was carried out in academic institutions. Large scale high speed test facilities were extensively used to develop the thermal protection systems and optimise the aerodynamic configurations for the reentry vehicles as well as to investigate the supersonic combustion in scramjet engines. The utility of these facilities faded after sufficient confidence in the design of reentry vehicles was gained. Further decline took place with the advent of the field of computational fluid dynamics. This resulted in eventual closing down of many test and experimental facilities and research interest in the field of hypersonics reached the lowest point. Fortunately the continuation of interest to develop scramjet engine technology during this lean period resulted in developing and building high enthalpy test facilities in Australia, Germany and Japan. Meanwhile researchers utilised the knowledge base for generating hypersonic flows in the laboratory to build many specialised experimental facilities to undertake chemical kinetics and microwave spectroscopic studies at very low temperatures.
There has been resurgence in the interest in hypersonic flow research in recent times due to the interest in commercialisation of space travel and also due to the unveiling of many space missions by the developing countries like India and China. With the realisation of the limitation of CFD codes and the high costs involved in the flight tests the emphasis is once again on the development of large scale ground based test facilities. Many new industrial size hypersonic test facilities have been built recently or are being built around the world and many academic institutions have also initiated research programmes in hypersonics. One of the unique features of the second phase of hypersonic research is the international collaboration to produce test data as well as to undertake joint research programmes in hypersonics, in spite of its application to the field of defence research. Hence the research is carried out in a more transparent way and there is free exchange of ideas as well as scientific manpower across many countries.
Currently the dissemination of scientific research results takes place through many nonspecialised aeronautical journals. Accordingly, there is a need to provide a common channel to publicise research findings. This can be achieved by establishing an international journal dedicated to the field of hypersonics. In order to address this need the International Journal of Hypersonics is being launched. The scope of this journal encompasses both the fundamental aspects of hypersonic flow research as well as hypersonic vehicle design. Specifically, the scope includes the fields like hypersonic vehicle design, materials for reentry vehicles, propulsion for hypersonic vehicles, hypersonic flow controls, sensors, launch vehicle issues, intakes for airbreathing engines, fuel mixing issues and high temperature chemical kinetics. In essence the journal will accept submissions in all areas related to hypersonics.
