Agreement with US-based aircraft manufacturer marks milestone in market penetra-tion by First Tier Supplier
Diehl Aviation, First Tier Supplier for aircraft cabin interiors and aircraft systems products, has reached an agreement with Boeing to develop and supply emergency power supply equipment for all versions of the 787 Dreamliner aircraft. The company’s unit Diehl Aerospace has already started the development work of the "Emergency Lighting Power Systems" (ELPS) for the aircraft type, with series deliveries expected early in next decade.
Diehl has a long and successful track record of supplying ELPS products to several aircraft manu-facturers, however, reaching the agreement with Boeing for the 787 meant winning a new cus-tomer for that product segment. For the Boeing 787 Dreamliner, Diehl already supplies the cabin interior lighting as well as other systems components and – in the case of the 787-10 – cabin ceil-ings and doorway lining parts.
The ELPS for Boeing’s 787 is comprised of two parts: The "Emergency Light Control Unit" (ELCU), which replicates complete battery control and charge and acts as an interface between the aircraft and the emergency lighting, and the "Emergency Battery Unit" (EBU). Diehl developed a smart battery concept over the last few years, which will now be employed for the 787 ELPS: a modern lithium-ion battery will be used for the Boeing products, based on Diehl’s experience with this technology.
