Lightweight Construction for Aircrafts

The classical requirement to be met in aircraft design is low weight combined with optimum mechanical properties. ROHACELL^® is widely used as core material for demanding sandwich structures, such as e.g. landing gear doors, pressure bulkheads, stringer stiffened panels, flap vanes, engine cowling doors and flight control surfaces.

ROHACELL^® shows outstanding strength - to - weight ratio even at elevated temperatures and excellent fatigue behavior. Due to the good resistance to compressive creep, it can be used under high temperature and high pressure autoclave and resin infusion processes.

Rotor Blades for Helicopters

ROHACELL^® has become an integral part in a whole range of helicopter rotor blades made by a wide variety of manufactures. Using Röhm's in-mold pressing technology fot the EH 101, GKN Westland produces the biggest helicopter rotor blade to date, which is approximately 8 meters in length.

The durability of the main and tail rotor blade with ROHACELL^® is guaranteed for the lifetime of the helicopter.
