Book excerpt: The determination of engine inlet, and nozzle performance at transonic speed is one of the most difficult experimental tasks encountered by aerodynamicists. The characteristics of the engine installation (inlet and nozzle) depend on an interaction of the engine flow and the external flow. At transonic conditions small variations of the initial flow properties approaching the boattail can produce significant effects that are difficult to predict and evaluate. In view of the importance and wide interest in the problems of nozzle testing techniques in transonic flow, a special effort is reported to develop an international program of research. The presentation of the results has been organized into two parts. The first part includes a detailed description of the experimental technique used, of the parameters investigated, and sample data from the tests conducted in each facility. The second part contains a critical analysis of the effects of the various parameters investigated.

Download or read book Technical Evaluation Report on the PEP Working Group No 4 on Improved Nozzle Testing Techniques in Transonic Flow written by F. Jaarsma and published by . This book was released on 1976 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report contains summary and conclusions on the test reports and joint analyses performed by a Propulsion and Energetics Panel Working Group on nozzle testing techniques. The original work from eight facilities and five nations was described in AGARDograph 208 along with an analysis of the reasons for variations in tests performed with a common model. This evaluation report provides conclusions and recommendations based on those analyses. It addresses effects of wind tunnel static pressure, Reynolds number, boundary layer, model support, wall interference, buoyancy, afterbody geometry, nozzle pressure ratio, and jet temperature.

This book was released on 1976 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental program was conducted to investigate the interaction effects which occur between the nozzle exhaust flow and the external flow field associated with isolated nozzle afterbody configurations at transonic Mach numbers. Pressure data were obtained from three afterbody geometries with boattail angles of 10, 15, and 25 deg at Mach numbers from 0.6 to 1.5 at zero angles of attack and sideslip. Cold (High-pressure air) and hot (Air/ethylene combustion) jet test techniques were used to simulate and duplicate, respectively, the nozzle exhaust flow for a sonic jet installation. Nozzle exhaust temperature was varied from 540 to approximately 2,900 R. The most significant results pertain to those effects on boattail pressure drag caused by exhaust plume temperature and flow asymmetry (Model support strut induced). The differences obtained in boattail pressure drag between the cold jet simulation and hot jet duplication results were significant at nozzle pressure ratios representative for turbofan and turbojet engines at subsonic Mach numbers. Adjusting the cold jet nozzle pressure ratio to correct for changes in the exhaust plume specific heat ratio with temperature did not account for the differences observed. Flow asymmetry effects were Mach number and nozzle pressure ratio dependent and increased in severity as the boattail angle was increased.
