Lufthansa Technik and QinetiQ Join Forces in Cabin
Systems
VIP and executive jet travel stands to get a hush kit for the
cabin in the near future as the result of a memorandum of understanding
between MRO Lufthansa Technik (LHT) and UK-based technology provider
QinetiQ. In addition to helping LHT with various aspects of its
cabin systems product line and newly certified wireless local
area network, QinetiQ (pronounced "kinetic") is also
working on a passive/active noise attenuation system that could
make cabins significantly quieter.
In partnership with Ultra Electronics, QinetiQ designed and is testing a noise-reduction
system for aircraft trim panels using both active and passive elements
to connect the panels to the fuselage. The panels are a prime source
for transmitting broadband noise, produced by airflow over the fuselage,
into the cabin. Laboratory tests on synthetic trim panels indicate
the new system can cut panel noise by at least 10 dB, or a factor
of two. A full flight demonstration is planned for early 2004.
Under the MOU, QinetiQ employees will provide services at LHT's
completion centers and MROs.
