Lightweight pipes for
aircraft high-voltage cable
conduit lines
To improve the overall fuel efficiency
and reliability of its new commercial
aircraft platform, the Commercial Aircraft
Corporation of China (COMAC) selected
Victrex pipes rather than metal tubing
for use in high-voltage cable conduits.
The new thermoplastic solution, which is
claimed to deliver weight savings of up
to 45 per cent, is being supplied through
the partnership of Beijing FeiHang JiDa
Aviation Technology Co, Ltd and Victrex.
COMAC and Beijing FeiHang engineers
are working with Victrex to address the
challenges of launching a civil aircraft
that is safe, cost effective, comfortable
and environmentally friendly.
The Victrex PEEK-based tubing
surpassed airworthiness testing in
China, which included maintaining
operational performance under impact,
loads, temperature variations, and
other environmental conditions. With
the technical expertise and support of
Victrex, the companies were able to
design a lightweight high-voltage cable
protection system within a much shorter
development cycle.
Victrex pipes are typically used in the
replacement of aluminium, titanium and
stainless steel tubing systems. For this
specific application, the Victrex PEEK-
based tubing was tested and validated
by COMAC, and achieved weight
savings of up to 45 per cent when
compared with titanium equivalent
tubing. This weight reduction can lead
to both improved fuel efficiency and
a reduction in CO 2 emissions. The
durable tubing system also serves as
a shock absorber in the protection of
the cables.
“Victrex is focused on delivering high-
performance solutions that can help
airframers and tier suppliers achieve
their goals,” stated Xue Wei, aerospace
key account manager at Victrex. “It is
rewarding to partner with companies
like Beijing FeiHang to achieve the
best results, not only in component
performance, but also in delivering
improvements in efficiencies.”
Victrex collaborated with the engineering
teams to design a system that is able
to take advantage of a much quicker
manufacturing process that does not
require machining or anti-corrosion
treatments as metals would.
