Aerospace
Highest standards – highest precision

The aviation industry is considered the supreme discipline among high-tech industries: extreme demands on safety, weight, temperature resistance, and long-term reliability make it a touchstone for every component. ttv develops and supplies sealing and plain bearing solutions that not only meet these requirements but exceed them. Our components are used where no margin for error is permitted.

Aviation requirements

 

 

Requirements in the aviation industry

Components for aviation applications must function reliably for decades under constantly changing pressure, temperature, and environmental conditions. The key requirements:

• certified materials with aviation approval
• Temperature resistance from –60 °C to +200 °C
• lowest weight with maximum performance
• absolute tightness even under vacuum and pressure changes
• Durability, maintenance-free operation, and documented traceability

ttv meets these challenges with heavy-duty, customized sealing and plain bearing solutions that are both technically and economically impressive—and prove themselves in daily use.

TTV - Sealing technology for controlled use above the clouds

As an experienced partner to aviation suppliers, ttv develops precisely designed sealing solutions, e.g. for cargo loading systems, drive units, actuators, flap controls, and more. Our engineering expertise, combined with high-quality specialty elastomers such as FVMQ (fluorosilicone) or FFKM, guarantees long-term stable function even under the extreme conditions encountered at flight altitude or in the engine environment.

Production takes place under strictly controlled conditions with complete batch documentation and compliance with customer-specific quality and testing requirements.

APPLICATION:
O-rings in the power drive units (PDU) of the cargo loading system in the Airbus A380 – the world's largest passenger aircraft.

REQUIREMENT:
Absolute tightness under changing pressure conditions, media resistance to hydraulic oils, and temperature stability from –55 °C to +200 °C – throughout the entire life cycle of the aircraft.

SOLUTION APPROACH:
ttv developed special O-rings made of fluorosilicone (FVMQ) for the drive units of the SE-PDUs (Single Element Power Drive Units). These PDUs were developed by Rheinmetall Defence Electronics in cooperation with Wittenstein and enable independent control of roller drive and lifting movement for cargo pallets in the cargo hold.

RESULT:
Reliable sealing in a highly sensitive system with maximum durability—the ttv O-ring meets all requirements for tightness, elasticity, and media resistance in the A380 cargo loading system. The solution is still in successful series production today.
