Altair Selected by Diehl Aerospace for 787 Cooperation

Altair consulting services and HyperWorks technology support Diehl to develop the 787 Dreamliner cabin lighting system

TROY, Mich., April 18 /PRNewswire/ -- Altair Engineering, Inc., a leading global provider of CAE technology and services that empower client innovation and decision making, recently announced that Diehl Aerospace GmbH, a leading supplier of aircraft systems, system solutions and equipment solutions for the aerospace industry, has chosen Altair Engineering as its simulation partner for structural analysis and weight optimization. The decision to partner with Altair followed close project collaboration between the two companies to successfully develop the 787 Dreamliner cabin lighting system.

In this project, Altair Engineering was responsible for all the simulation requirements including finite element analyses, design and weight optimization, structural concept development and load calculations using the Altair HyperWorks CAE technology suite. Altair's consulting services also included the reporting of FEA results according to FAA regulations and support during the certification process. Both parties plan to continue the successful partnership in future development programs.

"The 787 General Lighting System and interior airplane integration generated a new approach of mechanical development for Diehl Aerospace CCI," said Michael Wenzel, technical project manager of the 787 Lighting System at Diehl Aerospace. "Altair provided great support to this program, with reliable tools and a development staff that was highly flexible. They also contributed strongly to the project deployment with workable schedules and superior ideas."

Altair engineers leveraged HyperWorks powerful CAE technologies including HyperMesh for pre-processing, HyperView for post-processing, and RADIOSS to solve complex analysis problems to support FAA certification. In order to develop lightweight, structurally efficient systems for the Dreamliner program, Altair engineers used Altair OptiStruct to synthesize design proposals and to structurally optimize systems and components.

"The collaboration between Diehl Aerospace and Altair Engineering started in the spring of 2006," said Dr. Detlef Schneider, Managing Director of Altair Engineering, Germany. "This cooperation is now entering a new level to develop truly innovative system solutions for the aircraft industry. This valued relationship with Diehl emphasizes Altair's key market differentiator in our ability to deliver high-end consulting services together with best-in-class technology solutions. We look forward to working even closer with Diehl and the aircraft industry to meet today's and tomorrow's design challenges."
