A novel manufacturing process is used to fabricate the inflatable seals that secure the cockpits of fighter planes.
Worldwide aerospace sealing developer and manufacturer Busak + Shamban uses a novel manufacturing process to fabricate the inflatable seals that secure the cockpits of fighter planes.
Busak + Shamban's associated manufacturing company, Trelleborg Sealing Solutions Cadley Hill, uses a novel manufacturing process to produce inflatable cockpit seals.
These are fitted to the edge of the canopy of fighter planes.
When the canopy closes, the seal inflates, filling the gap between the plane's cockpit and its canopy, ensuring total sealing integrity.
A challenge to manufacture, the seals must be capable of operating at service ceilings of up to 15,000m, maximum speeds of 2000km/h, rates of climb of 12,000m/min and under extreme pressure.
Quality is paramount, as even a pinprick in the seal between the cockpit and the plane could put the pilot's life at risk.
Although high technology products, they are still hand fabricated in tools the full sise and shape of the jet fighter cockpit.
The inflatable seals are built up layer by layer, cured within the tool, then tested at line side.
Adrian Roberts, Product Manager for Trelleborg Sealing Solutions Cadley Hill says: "We lead the market in development and manufacture of one piece inflatable cockpit seals".
"We have produced these for the Tornado, M346 and Eurofighter Typhoon to name but a few".
