AGE
• Charge and Recovery• Below Boiling Point fluid will not charge by standing pressure.• Compressor can not be ground run ‘easily’• Below Boiling Point Conventional Recovery Equipment Does NOT ‘work’• Close to Boiling Point Conventional Recovery Equipment is ‘challenged’• AGE Requirement to Charge and Recover from -40 to +50°C
• Ground Test• Option A …. Ram Air Blower• Option B ….. Work like the Cooler LRI

Leak Detection
• In Manufacture• Helium – Chamber Testing 10-5 to 10-6 m.bar.l.sec-1• Mass Spectrometer (Turbo Molecular Pump)
• Why helium• Not because of its ‘searching’ properties (what ever that is?)• Not because of its Molecular size (10-7 m.bar.l.sec-1)• Its because we can quantify the leak rate (using standard gas equation)
• On Flight Line• Helium• Ion Science Gas Check• WISE Sensor (Semi Permeable Membrane)• Hand Held Detectors ‘a waste of time’• FLIR?• More FLIR?
