C919 Ends First High-Speed Taxi Test
Apr 26,2017
The
much-anticipated C919, the large homegrown passenger jet, has finished
its first high-speed taxiing test, and it is just one step closer to its
maiden flight.
Shanghai-based
State-owned Commercial Aircraft Corp of China Ltd, the manufacturer of
the C919, completed the high-speed taxiing test in Shanghai on Sunday.
Since
the first C919 rolled off the assembly line, COMAC has been conducting
tests in preparation for its first flight. So far, it has completed most
of ground-based pre-flight evaluations, including the low-speed and
medium-speed taxiing tests, to examine the whole aircraft and its key
components and connecting parts.
Wang Yanan, editor-in-chief of Aerospace Knowledge magazine, said high-speed taxiing tests are usually conducted at speeds of 230 to 260 kilometers per hour, with the front landing gear slightly lifted to simulate takeoff.
"It
is hard to evaluate the intervals between each high-speed taxiing
tests. It could be two to three days or one week. It could be very fast
if everything went right and no big technical faults occurred," Wang
said.
"Usually,
every latter high-speed test will be conducted at a faster speed than
the previous one, and more similar to the real condition before
takeoff."
He said COMAC will evaluate if the experimental performance is consistent to the designed capability, and the company would have to finish all the steps to guarantee the success of its flight.
For B787 of Boeing Co and A350 of Airbus Group SE, both widebody planes required high-speed taxiing tests of less than 10 times.
The
C919, the single-aisle, 168-seat and twin-engine jet, is a commercial
aircraft for medium-haul flights. The homemade plane is expected to
compete with the updated Airbus 320 and the new-generation B737, which currently dominate the market.
As
the manufacture of C919, COMAC is aiming to promote the development of
China civil aircraft industry. Jianzhong SHI, VP of COMAC, Kai LI, VP of
COMAC Shanghai Aircraft Design & Research Institute and Jianhua
WANG, ARJ21 chief technologist of COMAC Shanghai Aircraft Manufacturing
Co., ltd will attend Civil Aircraft Industry International Forum 2017 on
May 10th - 11th, in Shanghai which is hosted by Chinese Society of
Aeronautics and Astronautics, co-organized by Shanghai Society of
Aeronautics, OMAC Shanghai Aircraft Design & Research Institute and
COMAC Shanghai Aircraft Manufacturing Co., ltd .
