Highlights of cooperation with major customer UTAS


Two major milestones, the 1,000th GEnx and the 500th Trent XWB translating sleeve shipset crown the long-standing cooperation between UTAS and FACC.

FACC and UTAS can look back on a successful cooperation spanning several decades. The US aviation group placed its first order under the former name Rohr Inc. back in 1986. Since then, there has been a continuous stream of cooperative ventures, making UTAS one of FACC’s most important customers. 


In the summer of 2018, the partnership celebrated two important project milestones: the delivery of the 1,000th shipset of translating sleeves for the GEnx engine to UTAS. This contract was signed with FACC in March 2005. One outstanding feature of translating sleeves is their chevron design, i.e. the corrugated rear at the tail end of the engine. This product has since become a distinctive feature of the "Boeing Dreamliner" and makes a significant contribution to increasing its efficiency. The translating sleeves were developed by UTAS and FACC in close cooperation. FACC being mainly responsible for the design, industrialization and production. After merely two years of development work, the first translating sleeve was delivered in February 2007, thus sustainably strengthening the growth strategy of FACC’s Nacelles product family. The GEnx engine is intended primarily for long-haul aircraft with medium capacity, with state-of-the-art materials and design procedures generating a reduction in weight, noise emissions and maintenance costs, thereby increasing performance. It is used to power the Boeing 787 family and the Boeing 747-8. 


... 498, 499 and 500: Translation sleeve milestone for Trent XWB engines

At the end of July, the Engines & Nacelles division also celebrated a second anniversary: The 500th shipset of translating sleeves for the Trent XWB engine of the A350 XWB was delivered to UTAS. FACC has been a technology partner to UTAS for the Trent XWB program since 2009. In this project, FACC is responsible for the industrialization and manufacturing of the fully assembled translating sleeves.

We have been successfully collaborating with UTAS for decades and have jointly developed innovative technologies and products which increase the efficiency, cost-effectiveness and environmental compatibility of modern aircraft.

Friendly to the environment, saves weight and reduces noise emissions


The "translating sleeve" as a complete product includes the outer parts and movable blocker doors as well as the mechanical junction elements. The components are made of lightweight fiber composites and are delivered as a plug and play system: One of the special features is the dual-effect acoustic component surfaces which significantly reduce noise emissions. Thus, an extended frequency range is covered by two noise reduction areas, with noise emissions being reduced in two stages. The use of newly developed materials and processes also leads to improved sound insulation, further weight reduction and thus to even greater fuel savings and a longer service life. 

The FACC translation sleeves are manufactured in Plant 4 in Reichersberg, where one of the world's most state-of-the-art production facilities for lightweight fiber composite components is located. The plant is designed for maximum efficiency and cost-effectiveness. A high degree of automation is achieved through the use of new processes in surface treatment prior to bonding as well as innovative technologies to achieve noise reductions.
