Liebherr Aerospace has a history of introducing increasingly efficient aircraft system components—such as actuators, environmental control and thermal management systems, and landing gear—that have helped manufacturers improve efficiency and reduce carbon emissions.
As a logical next step, Liebherr has begun promoting increased electrification in aircraft systems, a field that is rapidly growing in importance with the emergence of the advanced air mobility (AAM) sector.
Aircraft of the future will rely less on traditional engine bleed air and hydraulic systems to power air management and actuation systems, in turn placing decreased or even zero burden on the vehicle’s primary powerplant, with a resulting increase in engine efficiency and reduction in emissions. Electric motor pumps would serve as the core element of decentralized hydraulic power systems.
Liebherr has produced electric systems for large aircraft for some time and recently launched a series of smaller electromagnetic actuators. They developed the actuators to satisfy demands from the AAM sector, where component size and weight are constricted yet reliability and power-to-weight ratios remain critical factors.
Local business Liebherr Singapore operates a service center dedicated to the Asia-Pacific region. Liebherr Singapore recently expanded the facility with a new high-performance hydraulic test cell and a repair-and-overhaul facility for heat transfer equipment. Adding in-region capability not only provides shorter turnaround times for customers but also reduces the amount of long-distance shipment required.
