OBIGGS for TIGER-UHT [ Return towards  Helicopters  ]

The comprehensive system offered by Air Liquide allowed it to provide a perfect match for the constraints of the TIGER helicopter specification. Air Liquide had to develop a particularly compact piece of equipment since it needed to be built into one of the helicopter wings.
Inert gas (nitrogen) is generated using a polymer membrane for air separation. This technology, developed by the Air Liquide Group for industrial applications, has been adapted to the restrictive aeronautics environment, and has been fitted to planes and helicopters for close on 20 years. The TIGER was the first helicopter in the world to employ an inert gas generator of this kind.

Apart from the inert gas generation itself, Air Liquide has incorporated into the same equipment a temperature control system, a pressure regulation unit and an oxygen analyzer so that the quality of the inert gas produced can be monitored on an ongoing basis.

A comprehensive provision<br/>Far from limiting itself just to air separation, Air Liquide is responsible for the whole nitrogen production line, from conditioning air from the "bleed" circuit to supplying gas to the tanks. Air Liquide is thus able to provide optimum inerting, perfectly adapted to the plane.

Continuous monitoring
In the event of a malfunction upstream or in the core of the inerting system, the system is able not only to feed information back to the pilot, but also to protect itself, thereby cutting down on maintenance and operating costs for the user.
