Mitsubishi aircra Corporation announced at the
Singapore Air Show that its MRJ regional jet will join
the long list of new aircra programmes to su er from
delays. ey are in good company - Airbus and Boeing
will testify to that.
Details of exactly what these delays will entails are
expected in the not so distant future, with the company
o cials saying that it was a combination of factors
rather than a single event - and did not involve the new
Pratt & Whitney PW1217G engine. e rst delivery
had been due in 2014.
"When you try and develop a game changing aircra
you always face some challenges," said vice president
marketing and sales, Hank Iwasa. Iwasa was upbeat on
the prospects for the MRJ, saying that the manufacturer
had several "very good" campaigns running, including
a potential Asian and US customer. Vietnam Airlines
is known to be considering the MRJ as a sub 150-seat
Mitsubishi is con dent the programme will prove
a success, pointing to the fact that one-in-four ights
is made by a regional jet, and that globally, weekly
departures have grown by 45% from 2003-to -2011,
compared to an average across all aircra types of 41%.
Mitsubishi expects the Asia-Paci c proportion of the
global regional jet eet to grow from 8% to 20% by
2030, which would mean around 1,200 jets for the
In terms of programme status, the Pratt & Whitney
PW1217G geared turbofan that will power the MRJ
completed 550 hours and 1,110 cycles of ground test by
the time of the Singapore Air Show. " e performance
meets/exceeds our expectations," says Mitsubishi.
Engine ight testing will take place this spring.
Mitsubishi claims that the MRJ90 will have a 40%
reduced noise area compared to the Embraer EMB190,
and adds that both the MRJ70 and MRJ90 are well
within chapter 4 and expected Chapter 5 noise limits.
Chapter 5 noise limits are expected to be within 10db
of Chapter 4 levels - the MRJ90 is expected to be
16.8db within Chapter 4, and the MRJ70 within 19db.
In terms of fuel burn, Mitsubishi says the MRJ90 will
be 20% lower than the EMB190, providing cost savings
of US$1.4 million per year per aircra , and reducing
annual aircra CO2 emissions by 4,000 tonnes.
Mitsubishi had a mock-up cabin at Singapore,
where it said its MRJ70/90 cabin was wider (108.5
inches) than the EMB170/190 (108 inches) and
CRJ700/900 (100.5 inches) and higher (80 inches)
than the EMB170/190 (79 inches) and CRJ700/900
(74.7 inches). It also claimed to have the widest seat in
two x two con guration at 18.5 inches, compared to
18.25 inches for the EMB170/190 and CRJ700/900
at 17.3 inches. Cabin features on show in Singapore
included slim seats with new fabric developed for the
ere are currently 130 orders from three customers,
although these include options and an MoU. ANA
has 25 rm orders, with a further 10 options. Trans
States Holdings of the US has 50 rm options with 50
options. And ANI Group Holdings of Hong Kong has
an MoU for ve aircra .
Mitsubishi is yet to rm up its plans for a stretched
version of the MRJ, the MRJ 100 X. "A decision will
be taken a er the rst test ight," says Iwasa. e rst
ight is due later this year.
Mitsubishi announced late last year that the MRJ
had successfully became airborne in the hydraulic and
ight control system rig test, known as "iron bird".
e iron bird is one of most signi cant system
integration test of the development process to test the
manoeuvring functions of the MRJ: it is a system which
consists of ight deck, hydraulic and ight control
equipment, on-board so ware to be loaded on the
actual aircra , and simulation computers creating the
all of ight environment.
is testing of "iron bird" is being conducted at
the MRJ dedicated experiment building built within
Oye Plant (located in Nagoya) of Mitsubishi Heavy
Industries, which is responsible for manufacturing and
testing the MRJ as the major partner to Mitsubishi
Mitsubishi is confident that the imminent schedule slip for the MRJ
will not affect the programme's success, writes Colin Baker
