Comac%20Ponders%20Materials%20For%20C919
("One structural decision that has been made is the material for the tail
and moveable surfaces: they will be of composite, as they routinely are on
new commercial aircraft these days. But the material for the center wing box
, outer wing boxes and fuselage is still under study"0
My comment: The quotation is the summary of teh article. But to me, the most
important is the last two paragraphs.
"The low priority now accorded to the ARJ21 was evident at the Shanghai
International Business Aviation Show, held here April 13-15 * * * The ARJ21
looks increasingly likely to be an unloved orphan until the C919 enters
service—in 2016, according to the schedule. The C919 is a project of
national priority for the government of President and Communist Party
Chairman Hu Jintao. The ARJ21 is not.

"The ARJ21 is no longer a priority" web page 1
"[Parker Aerospace’s Vice President Pui] Ho expects the new airplane not to
be a mere clone. 'They want it to be advanced when it enters into service,'
he says. The Parker hydraulics for the C919 are a new design, as are other
elements of the new airplane. It uses a common core computing architecture
that Smiths Industries, now GE Aviation Systems, developed for the 787. The
C919’s powerplant is the Leap-X1C, the first edition of CFM International’
s successor to the CFM56 series." web page 2
"The ARJ21 brought outside contracts for Alcoa on aluminum alloys" web page

"From his 31st-floor office in a glass-and-steel Shanghai high-rise, Parker
Aerospace’s Ho looks down on a street filled with Audis, Buicks,
Volkswagens and other well-known brands. All bear Chinese characters on the
trunk identifying them as produced in-country, but that has not hurt their
sales at home. ‘I think it’s overblown, a little bit,’ he says of
concerns about IP protection. 'The question is, do they have enough programs
to make them good enough [to compete]. Right now, they do not. Right now
they are not thinking so far ahead. It’s a competitive world. We’re not
going to stagnate just because of the Chinese.'" web page 3
