Technical Evaluation Report on the PEP Working Group No. 4 on Improved Nozzle Testing Techniques in Transonic Flow.

摘要

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.
