The progress made in the field of propellants and combustion in the US and in Asia and Europe covering a broad range of efforts and new starts are discussed. The Japan Aerospace Exploration Agency (JAXA) has been involved in the development of combustor technologies that reduce NOx emission levels to 20% of the ICAO (International Civil Aviation Organization) CAEP-4 (Committee on Aviation Environmental Protection 4) regulation under the TechClean project. The core of the project is to develop next-generation high-pressure-ratio engines and optical techniques for evaluation of combustor performance. The improved facility has continued to a Japanese national project called R&D of environment-Friendly Small Aircraft Engine performed by domestic industries under the support of the Ministry of Economy, Trade and Industry. Velocity profiles were measured in at Mach 2 supersonic flow over a cavity that simulates the piloted flow in a scramjet.
