High Temperature Problems in Gas Turbine Engines.
Abstract
These Conference Proceedings contain 39 papers presented at the 50th Meeting of the AGARD Propulsion and Energetics Panel, held at Ankara, Turkey on 19-23 September 1977. The papers were grouped into eight sessions on motivation and survey, turbine cooling techniques, combustors, afterburners and nozzles, materials and coatings, mechanical problems, effect of cooling on aerodynamic performance, measuring techniques, and on prediction methods. The purpose of this meeting was to review and highlight the main problems associated with the attainment of high temperatures in aircraft gas turbines. Attention was focussed on methods of cooling components in the hot portion of the engine, notably the combustor and reheat liners, nozzle guide vanes and turbine components. Progress in new materials and protective coatings was discussed. Fuel and combustion problems associated with operation at high gas temperatures were considered as well. Furthermore, new measuring techniques and heat transfer prediction methods were discussed. Also included are the Technical Evaluation Report and the discussions which took place after most of the presentations. (Author)
