GKN Aerospace is showcasing emergency flotation and fuel system technologies here at its Heli-Expo booth (No. N2608).
Emergency flotation system
The FAA has approved the Sikorsky S-92 for sea state 6 (SS6) conditions, meaning up to 20-foot waves. Thanks to additional sponson floats, the S-92’s emergency flotation system becomes the first one to be FAA certified for SS6, according to Sikorsky.
“This system was designed by the S-92 landing-gear design group, with close coordination with electrical and airframe design and structural analysis,” said Ben Del Monte, chief of propulsion/landing gear/mission systems.
GKN Aerospace (Booth No. 4123) has a better idea, and it floats. The UK-based company has created a new helicopter emergency flotation system that it says offers a 50-percent saving in volume and a 25-percent weight reduction. It is an adaptation of technology applied in European Space Agency programs and uses cool gas generator (CGG) technology.
