Abstract:

The NAD is the Noise Attenuation Device. It is based on results of sub-scale testing undertaken for a Strategic Environmental Research and Development Project SERDP and Navy Environmental SDI co-sponsored project Reduction of Particulate Emissions from Jet Engine Test Cells JETCs Using an Annular After-Reactor AAR. Those sub-scale tests demonstrated the scientific and engineering basis of the AAR for reducing both particulate matter and nitrogen oxide emissions from a jet engine. They also provided the basis for using the concept of the AAR to reduce jet engine noise. Therefore the full-scale NAD was designed, specifically, for its application to the Navys F-414 jet engine, a cornerstone Navy engine. Milestones leading to this application were a test the NAD on the non-after-burning J-52 engine, and b evaluate it with the after-burning F-404 engine. Those two milestones have been completed and the results are reported here. Testing of the NAD with the F-414 engine has been approved and is planned for an ESTCP-funded project.
