abstract

As part of the DoD Base Realignment and Closure process, the unique Navy capability to test aircraft engines under various environmental conditions is being transitioned to the Air Force. A new facility, using two modified sea-level Air Force T-9 test cells as building blocks, formed the basis of the new design. The structural design of the test cells and test control building was based on the aerodynamic and acoustic requirements for testing large afterburning turbojet/turbofan engines. Major construction has passed the 90-percent completion milestone. Aerodynamic criteria were defined in 1/12th-scale model tests of an engine installation using an F110 engine simulator. Modifications were then made to the basic T-9 test cells to allow ram air duct direct-connect capability. Following construction, activation/validation of the test facility will be conducted with an actual F110 engine, run in both direct-connect and bellmouth inlet configurations. Initial Operational Capability is scheduled for September 1998. Technical aspects of the facility design, construction, and ram air duct are described. Final system capabilities are airflow of 249.48 kg/sec; inlet air temperature range of 219 to 503 K; and inlet air pressures up to 206.85 kPa (1.1 Mach number). Environmental conditions of high and low temperature, water and ice ingestion, sand ingestion, and salt air corrosion can be duplicated. Engine transient operation, and mission profile endurance tests with simulated inlet conditions of forward flight velocities will be available to both government and industry users.
