Pressure Units Monitor Jet Blast Deflector Tests
Jet Blast Deflectors
Jet Blast Deflectors (JBD), located behind the catapults aboard aircraft carriers, deflect high energy exhaust from the jet engines to prevent damage and injury to other aircraft and personnel within a close proximity.
After use, the JBD quickly retracts flush into the flight deck so that people and other aircraft can move across. An elaborate system pumps coolant fluid through the panels to dissipate the intense heat focused onto the JBD by the aircraft engines, cooling it enough to protect the crew and prevent damage to the tires of aircraft rolling across the retracted panel.
When it becomes necessary to modify the JBD to accommodate new aircraft, the configuration needs to be tested to ensure that the cooling capability is sufficient. The test stand for this critical cooling system records 103 parameters, including the overall flow rate, to determine the effectiveness of the new configuration.
The test uses 57 LORD Sensing-Stellar Technology series GT180 jet differential transducers to monitor the supply and outlet pressures, and 45 LORD Sensing-Stellar Technology series DT190 differential transducers for jets located throughout the system.
