| Touching down at more than 150 mph,
an airliner possesses a great deal of kinetic
energy which must be dissipated by the wheel
brakes and the engine thrust reversers. As a key
safety-critical device, engine thrust reversers
are subject to rigorous and prolonged cyclic
testing. Until
the advent of thrust reverser ducts, the testing
of reversers in engine test cells presented
severe problems. When the engine reverser is
deployed, the exhaust gas stream is directed
forward. Consequently, the engine may ingest
exhaust gas, potentially causing catastrophic
damage.

To overcome this problem, Exign
Technology designs thrust reverser ducts which
are installed in the cell to receive the reverser
exhaust stream and redirect it towards the cell
exhaust duct. The aerodynamic and structural
design of these ducts is so effective that
engines can be operated continuously at full
reverse thrust in the test cell. The design of these ducts
is a typical example of Exign Technology’s
capacity to overcome novel engineering
challenges.
