The Liebherr team has reached a major milestone with the delivery of the first engineering prototypes of the Nose Wheel Steering Remote Electronics Unit for the Boeing 787 Dreamliner and Main Gear Steering Control Unit for the Boeing Model 777 family of airplanes.
Liebherr started the program for the two units in the second half of 2018, followed by the in-time design and the implementation phase. The company provided the first engineering prototype units for testing at Boeing in February 2020, after intense testing at the Liebherr facilities.
This marked the first time for Liebherr to supply stand-alone electronics. Standalone electronics is electronic hardware with a software operation system, as well as application software to integrate into dedicated airplane systems.
Boeing engineers successfully carried out development tests and continue to perform testing to confirm the correct operation of the components. The Boeing and Liebherr Teams are working closely together on the final reviews and preparation for qualification testing.
The high level of functionality and maturity of the Liebherr products is already evident from the engineering tests completed, which will support a successful qualification phase in advance of Liebherr’s serial release and Boeing’s subsequent entry into service on the 777 family and 787.
The teams are very satisfied with the progress to date, underscored by a successful Critical Design Review between Boeing and Liebherr; a great basis for further Liebherr stand-alone electronics system projects.
