Specific Challenge:The aim of the project is to experimentally evaluate the performance and installation effects of Ultra High Bypass Ratio (UHBR) engines with Adaptable Area Nozzles (AAN). First, the effect on powerplant performance will be assessed for isolated configurations. The analysis of the isolated configuration will support the sizing of adaptable nozzles of different concepts. In a second step, the effect on powerplant performance will be assessed for installed configurations. The analysis of the installed configuration will show the effect of the mounting system and wing on the powerplant performance. The effect of the engine jet interactions with the airframe will be studied. For the full topic description see the Call Text Document (Annex of Workplan) published with this call.
