Liebherr-Aerospace Selected for KC-390’s Bleed System
In February 2012, Embraer Defense and
Security, based in São José dos Cam-
pos (Brazil) selected Liebherr-Aero-
space to provide the bleed controller
and bleed valves of the KC-390 military
transport aircraft.
The latest-generation bleed system
features the most advanced com-
pact electro-pneumatic bleed technol-
ogy, which has gained an unmatched
experience in operation on a wide ar-
ray of aircraft models across the world.
It provides high reliability, optimized
safety and comfort conditions as well
as proven robustness under all operat-
ing conditions. The integration into the
aircraft and the system-performanc-
es will be further strengthened by the
test rig that will be set up at Liebherr-
Aerospace’s recently opened test center
in Toulouse, France. Liebherr-Aerospace Toulouse SAS will
develop and manufacture the system
that features integrated control archi-
tecture with high-reliability, high-per-
formance, lightweight pneumatic and
mechanical components. This new
partnership in defense and security
further expands the already long last-
ing relationship between Embraer and
Liebherr-Aerospace.
Flexibility and a Vast Array of Products
for the Aviation Industry
Air-to-Air Refueling with New
Liebherr Hose Drum Drive System
When UK-based Cobham Mission Equip-
ment planned their future air-to-air re-
fuelling equipment, they chose Liebherr
to develop the core motor control subsys-
tem in 2007. The hose drum drive system
(HDDS), based on Liebherr-Aerospace’s
proven power electronic technology, pro-
vides the motive force to trail and rewind
the refuelling hoses.
It comprises a 10 kW electric motor con-
trol unit, a dump resistor pack for dissi-
pating power during regenerative electric
braking and a geared motor unit to drive
the hose drum.
The HDDS is a joint development by
Liebherr-Aerospace Lindenberg GmbH
and Liebherr-Elektronik GmbH in Lindau
(Germany). Liebherr-Aerospace in
Lindenberg concentrated on the em-
bedded system and motion control work
encompassing electronic systems, de-
velopment of control laws, airborne soft-
ware development and electric motor
development. Liebherr in Lindau focused
on airborne hardware development and
airborne equipment qualification.
The overall system integration was per-
formed by Liebherr-Aerospace to pro-
vide Cobham with a fully integrated sub-
system for wing refuelling pods and fuse-
lage refuelling systems.
The HDDS is currently certified for the
A330 MRTT application, and serial de-
livery has started. Certification for the
A400M platform is the next program
milestone.

From business jets over the latest helicopter programs and regional jets to special military applications: the
vast array of Liebherr-Aerospace products is a result of an over five decades lasting success story as a major
supplier in the global aviation industry.
