TRELLEBORG UNVEILS PIONEERING ROTARY WING AIRCRAFT SEAL

Trelleborg Sealing Solutions unveils a pioneering product that could “radically improve the reliability” of rotary wing aircraft.

Turcon

The Turcon® Varilip® PDR RT rotary shaft seal, which has already been proven to out perform other similar seal products, was developed to meet the ever-growing demand to provide seal integrity at increasingly higher rotational wing speeds.

Torben Andersen, Trelleborg Sealing Solutions Director of Aerospace, said: “This project started several years ago, when we wanted to find a seal that would provide a better performance at very high speeds, specifically for rotary wing aircraft.

“We knew that at high surface speeds, ensuring that essential lubrication is maintained was a major challenge and any leakage would compromise the operation of the aircraft. That’s why designing a seal that out performs anything that’s currently out there was so vital.”

During the development of the Turcon® Varilip® PDR RT rotary shaft seal, Trelleborg designed and commissioned bespoke high speed test equipment capable of running at speeds of up to 24,000 rpm and a test programme that closely followed the way rotary wing aircraft gearboxes work. This allowed developers to ensure that the seal met highly demanding application requirements. The team experimented with a number of different lip materials, marrying them to various seal designs and investigating the best lip geometries and lip features to select the correct profile and material.

Torben added: “This is a breakthrough. We’ve developed a process that facilitates a seal with less torque, friction and heat to reduce maintenance; one that will radically improve the reliability and boost the performance of rotary wing aircrafts.

“Though initially designed for this specific application, the work we’ve done shows that it also lends itself to other applications that require high speed rotary performance. We’re already generating interest from designers of electromechanical actuators and from a wide range of other market segments.

“For many years there has been a standard version of the Turcon® Varilip® PDR – but this new seal operates effectively with less power and is therefore more efficient. We’ve optimised the design so it can run on a range of surface finishes and coatings, including ceramics.”

Using Trelleborg’s bespoke testing equipment, the Turcon® Varilip® PDR RT rotary shaft seal has undergone more than 20,000 hours of endurance testing with latest designs operating at 3,500 hours leak free.

The recently signed distribution agreement combines the wide aerospace market presence of Trelleborg Sealing Solutions with the highly engineered metallic seals expertise of HEICO’s Jetseal, Inc.

Michel Prouff, Director Global Marketing Aerospace for Trelleborg Sealing Solutions, says: “Trelleborg Sealing Solutions continues to rapidly expanding into the European aerospace engine market and this new distribution agreement with Jetseal Inc. offers significant market opportunities for both companies.”

In addition to its wide range of aerospace seals, Trelleborg Sealing Solutions is now offering a full line of metallic seals, ranging from industry standard AS1895 e-seals to complex multi-convolution seals for sealing high pressure and temperature engine applications. Additionally, the new partnership will allow Trelleborg Sealing Solutions to offer seals for use in the hot section of the turbine engine up to +750 °C.

Trelleborg Sealing Solutions Announces Fire Test Facility for Aerospace Seals

Trelleborg Sealing Solutions is pleased to announce its new airframe/engine seal fire test facility located at its manufacturing facility in Northborough, Massachusetts in the U.S. This state-of-the-art fire test facility addresses aerospace manufacturers’ growing need to meet varying fire test requirements to comply with industry and customer standards for vibration and air flow.

TSS Fire Test Facility for Aerospace Seals

Trelleborg is among only a few seal manufacturers that deliver comprehensive in-house qualification testing, now including fireproof and fire resistance testing.

The investment made to commission the extensive capabilities of this testing facility will enable specific tests to be conducted for customers with a variety of qualification requirements. This facility allows Trelleborg to conduct customer specific tests to meet a variety of qualification requirements, such as ISO/TR 2685, which calls for vibration and flame exposure of 1100 degrees Celsius / 2000 degrees Fahrenheit for fifteen minutes without allowing flame penetration or other defined failure modes.

Quinn Collett, Airframe Americas General Manager, says: “As a global leader in sealing solutions, Trelleborg is thrilled to be able to offer customers a fire test facility that will considerably speed the development of products without the delays involved in submitting to a third-party facility for validation. This approach strengthens Trelleborg’s focus on its R&D initiatives and technical improvement capabilities.

“The Fire Test Facility fits well with the existing Global Marketing Aerospace test capabilities, which comprise a multitude of test rigs specific to aerospace seal applications. Trelleborg can assist customers in developing the ideal qualification test plans and procedures with customers picking which tests they need to have as proof of the capabilities of their products. Such a modular and forward thinking approach helps speed up response & development time while keeping costs down. Typical applications can include aircraft interiors, engine fire seals and ancillary components such as oil pumps and hydraulic systems.”
