Although it no longer builds turboprop airliners,
Embraer is still keeping watch on demand in the
sector, where it foresees requirements for 2,440
machines with more than 30 seats by 2030.
Of these, 2,000 -- or nearly 82 percent -- will
accommodate 60 or more passengers, with the
majority being delivered a er 2020. e Brazilian
manufacturer says demand for such aircra is driven
by high oil prices and increasing attention to noise
and other environmental factors. e company
adds that turboprops are mainly attractive for use
in short-haul and niche markets.
Half of the aircra will be replacements for
older models, since the global eet of almost 2,100
turboprops in service last year had an average age
of 15 years, according to Embraer. By 2030, more
than 40 percent of current machines, or 855 units,
will remain in ser vice and predicted deliveries will
expand the eet to 3,295 aircra .
Within this global analysis, Embraer notes
that while turboprops account for about 17
percent (485 aircra ) of the 2,935-strong 2010
Asia-Paci c commercial aircra eet, they only
comprise 6 percent (85 units) of the region s
1,400-aircra order backlog. During 2011-30,
some 660 turboprops are forecast to be delivered in
the region, with 41 percent replacing older types.
In the 20-year period, the region s fleet is
expected to grow from 485 machines to 920, with
39 percent of current aircra still operating in
2030. e forecast concludes that China -- where
turboprops only comprised 2 percent (or 30
aircra ) of the 2010 eet -- will require 120 new
turboprops, with one in four as replacements for
wedded exclusively to P&WC as an engine supplier,
saying that it is open to investigating all possible
technolog y o erings, such as any engine that could
emerge from General Electric s CPX38 project study.
"The best solution will balance technolog y,
costs, and risk," the company says. For its part, ATR
stresses what it needs from any powerplant provider
wanting to do business. "Engine manufacturers clearly
understand that the key element of future turboprop
engines is [to] keep on improving fuel e ciency and
to minimise environmental impact, while further
reducing operating cost for airlines," the company
Both airframe manufacturers con rm the need
to fully understand airline requirements before
embarking on a 90-passenger model. Bombardier s
Pratt is at pains to emphasise that, despite "keen
interest" from customers and suppliers, any further
Dash 8 stretch remains only "a concept currently
under consideration", for which launch or delivery
timing has not been established. "We will continue
to look at its potential for [market] success, based on
customer feedback," he says.
Bagnato says ATR is working "with operators and
suppliers to establish a clear picture of demand is and
possible optimal solutions".
In turn, engine-maker P&WC says it is maintaining
communications with airframe manufacturers and
will base the key attributes of its NGRT engine on
the likely aircra requirements. "We are continuously
re ning our studies to ensure our customers potential
needs are met," says Dusault.
He con rms that, having de ned necessary engine
attributes, P&WC has started detailed design
of an advanced core, including a high-e ciency
compressor and low-emission gas generator. Core-
demonstrator tests, beginning in September, will
"validate technologies aimed at improved e ciency,
advanced aerodynamics, and lower emissions". e
core will make use of some technologies and materials
developed for P&WC s new PurePower geared
turbofan engines, the company con rms.
e manufacturer has completed the NGRT s
design architecture and work should lead to a
" nished product" sometime next year, says Dusault.
Engineering drawings have been released and by June
P&WC had begun machining initial components.
Parts will be tested individually under a schedule
that anticipates running the compressor system by
"We want to be sure we can provide the right solution for
the operator's needs." -- ATR Chief Executive Filippo Bagnato
Embraer watches turboprop market
Embraer has now withdrawn from
commercial turboprop manufacture.
