The Inlet and Nozzle Branch (RTE) conducts fundamental and applied research to advance the state of the art in inlets and nozzles for aircraft engines and other aerospace applications. The research is applicable to commercial and military aircraft and space propulsion systems.

The branch maintains and operates several test facilities. These facilities are used to:

• Produce detailed test data for validation of computational fluid dynamics (CFD) codes
• Measure the performance of advanced inlet and nozzle designs
• Study flow control concepts for improved inlet and nozzle performance
• Investigate nozzle aeroacoustic issues
• Provide inlet/fan interaction data
• Understand fundamental flow physics issues relevant to inlet and nozzle flows

• Design advanced inlets and nozzles
• Predict inlet and nozzle performance
• Model flow control concepts
• Understand aeroacoustic phenomena
• Model inlet/fan interaction
• Study fundamental flow problems
