This report summarizes the finding of an assessment. Section I provides a general introductory overview of the state-of-combustion-technology today and highlights some general projections and trends for the future. Section II gives a state-of-the-art review of the five special topic areas of interest covered during the assessment -- main burners, afterburners, combustion modeling, structural and mechanical design, and alternative fuels. Sections III and IV examine the advanced technology trends and projected technology needs, respectively, as related to each of the topic areas cited above. A five-year technology plan is outlined in Section V. Future aircraft propulsion requirements call for combustion systems capable of 1 accepting greater variations in compressor discharge pressure temperature and airflow, 2 producing heat release rates and temperature rises which will ultimately approach stoichiometric levels, and 3 providing high operational reliability and improved component durability, maintainability and repairability. In addition, the new requirements associated with exhaust emissions and fuel flexibility must be addressed. Consequently, as the combustor designer is confronted with the new requirements of the future, especially exhaust emissions and fuel flexibility, new design concepts may be required to provide an acceptable solution.
