The AEDC T-11 engine test cell at Arnold Air Force Base was recently modified as part of effort in the AEDC technology program to develop test and evaluation techniques that will prepare the Complex to meet future vision system weapon requirements. To implement a plug-in module concept, the T-11 plenum was modified by installing a spool piece that enabled the installation of a plenum apparatus and provided the interface for the plug-in modules. Pictured is the Research Cell R1D section that will become a plug-in module for T-11. (AEDC photo) AEDC T-11 engine test cell modified to expand its capabilities
The AEDC T-11 engine test cell at Arnold Air Force Base has been enhanced to perform a wide variety of research tests in addition to its primary role of testing small engines in a direct-connect configuration. The Air Force Project Manager for upcoming technology tests in T-11, Joshua Osborne, explained that one of the largest benefits is that this
