Safe Take-Offs and Landings - 
An Airplane Life Long

Landing gears are among the safety-relevant systems on an airplane. Take-offs, landings, taxiing along the runway – if there are problems here, then nothing else works. To prevent this from happening, Liebherr-Aerospace in Lindenberg is constantly working on innovative, efficient landing gear systems.

An average regional jet, for example, has a take-off weight of around 22 metric tons; a medium-sized long-haul airplane can weigh as much as 300 metric tons. For the specialists at Liebherr-Aerospace, the product lifecycle does not come to an end after the first design sketch, prototype production, certification and series delivery. In fact, the company also offers comprehensive servicing for the landing gear systems, which remain in service for up to 30 years, the lifetime of an aircraft. Alongside maintenance and repairs, Liebherr- Aerospace attaches particular importance to the continued further development and optimization of series products – in close coordination with the aircraft manufacturers. In order to realize this concept as effectively as possible, an In-Service Engineering Team was set up in Lindenberg (Germany). Around 30 specialists work on an interdisciplinary, cross-divisional basis with all the departments involved in the product manufacture and further development. At the same time, the team is the first point of contact for customers for all technical matters relating to the landing gear systems.

Technology for Tomorrow

Liebherr-Aerospace works together with Thales on the next generation of thermal and power management on-board aircraft. 

GETI is a French joint project of Liebherr-Aerospace and Thales Avionics Electrical Systems. It focuses on a smart electrical and thermal power management approach for more electrical aircraft.

By optimizing the electrical power consumption, the needs for cooling and the global weight of the systems, the results of GETI contribute to the ambitious environmental objectives in terms of CO2 and NOx emissions reduction defined by the Advisory Council for Aeronautics Research in Europe (ACARE) and the French Civil Aviation Research Council (CORAC).

Complex Testing at Liebherr
- From Specification to Certification

Impressive pictures of Liebherr-Aerospace’s state-of-the-art test and qualification center in Lindenberg (Germany)

In the test and qualification center at Liebherr-Aerospace Lindenberg GmbH, Lindenberg (Germany), the company offers the overall service from specification to certification and accompanies its customers throughout the whole process. 

Liebherr has complete flight control actuation and landing gear system testing capabilities. In a dedicated test center, various subsystems can be installed and tested together. The company designs and manufactures the test rigs for complete primary and secondary flight control systems integration including the test rig control load and failure simulation. For the development and integration of landing gear systems, subsystems and components, Liebherr-Aerospace operates advanced test and support facilities. The test set-ups and components are designed and built in-house; they are based on the concept of modular test rigs and fixtures, including electronic control and electronic data acquisition.

Less weight, faster final assembly, more flexibility: An Extremely Versatile Control Unit made by Liebherr

The ingenious concept of the Remote Electronic Unit developed by Liebherr-Aerospace offers plenty of advantages, thanks to digitization.

The electronic control unit made by Liebherr is mainly used to evaluate sensor data and to control systems locally, with the measured data being digitized locally and forwarded to a main computer. 

To fulfill various tasks, the Remote Electronic Unit can easily be adapted to the relevant requirements using the software. Until now, this had only been possible with correspondingly varying hardware. Thanks to its small size, the control unit can even be mounted directly in aircraft wings or on actuators, which means the cabling required previously is no longer necessary. This in turn not only shortens the wing production time considerably, but also reduces the total weight of the aircraft by as much as 500 kg in comparison with traditional construction methods with completely cabled actuators. 

Because of its modular design, the Remote Electronic Unit can be used flexibly in the aerospace and space industry. With its laser-welded capsule it can also withstand harsh maritime conditions.
