Cell 2 Specifications/Capability

The Large Dual Flow Rig (LDFR) in Cell 2 is designed for performance testing of scaled engine exhaust system models including thrust reversers, although most models requiring either force or flow measurement can be adapted to the facility. The rig is mounted on a three-component balance.
