Transitioning Navy aero engine test capability

Abstract

Abstract : The reduction in military force levels requires a corresponding decrease in the shore based infra-structure. Many bases and laboratories were selected for closure or realignment as part of the BRAC process. The Navy's aeropropulsion test facility at Trenton, NJ, would transfer its large and medium propulsion engine test capability to the Air Force's propulsion facility at Arnold Engineering Development Center, Arnold Air Force Base, TN. Two small altitude test cells will be disconnected and physically moved; the test capability of two large engine environmental test cells will be transferred by utilizing standard Air Force A/F32T-9 test cells as building blocks. The two T-9 cells will be modified to duplicate the ram air test capability of current Navy cells. The transition process is described from both technical and management viewpoints. Test facility requirements, funding, organizational responsibilities, partnering, and design and construction are discussed. Test cell scale model tests with engine simulators formed the basis for equipment modifications. Activation/validation efforts with appropriate engines will document the required test capability. Current program status and final test cell capabilities are presented. Criteria for engine performance measurement, engine/cell operability, and acoustical requirements are discussed. Operational capability for the altitude chambers is late 1997, and the large environmental sea level cells in late 1998.
