The
highly-efficient NEO (new engine option) single-aisle jetliner project is
another step closer to taking flight with today’s rollout of the initial
A320neo – a key milestone as Airbus continues on-schedule for the aircraft’s
maiden flight.
Prominently featuring the NEO branding on its livery, this aircraft –
designated MSN6101 in the company’s numbering system – is powered by Pratt
& Whitney PW1100G-JM engines and is the first in Airbus’ A320neo Family
developmental fleet. It is equipped with extensive flight test instrumentation
for handling qualities, performance and engine tests, along with the
high-altitude, and hot- and cold-weather campaigns.
In total, Airbus’ NEO flight-test fleet will comprise eight aircraft. This
includes two A320neos, one A319neo and one A321neo for each of the new engine
choices: Pratt & Whitney’s PW1100G-JM and the CFM International LEAP-1A.
The company’s rigorous A320neo Family flight-test and certification programme
is facilitated by the jetliner’s fly-by-wire commonality, as well as previous
flight dynamics testing during the Sharklet-certification campaign, explained
Sandra Bour-Schaeffer, Project Flight Test Engineer for the NEO programme at
Airbus. “We have optimised the flight-test programme – building on our family concept
– to progress through this process as efficiently as possible,” she said.
Once MSN6101 takes flight, Airbus will begin with initial development and
aircraft flight manual tests, before proceeding into its A320neo development
and certification phase and maturity campaign – to ensure the A320neo fully
meets customer requirements at service entry, which is scheduled for the fourth
quarter of 2015.
In addition, a second Pratt & Whitney-powered A320neo aircraft is planned
to join the developmental fleet this year – fitted with lighter flight test
instrumentation for noise, functionality, reliability testing and ETOPS
approval.
Airbus already is well advanced with “up-front” A320neo testing, including
approximately 250 flight hours performed on the company’s A320ceo (current
engine option) in-house developmental aircraft to evaluate hardware and
software for NEO flight control laws, and test bench validation of thrust
reversers.
To further prepare for first flight, Airbus will begin a “virtual flight-test
campaign” this summer, which includes simulator-based evaluations of flying
scenarios and aircraft systems.
Incorporating its new engine choices, along with the application of Airbus’
fuel-saving Sharklets wingtip devices, the NEO shares over 95 per cent
commonality with CEO aircraft – while delivering at least 15 per cent reduction
in fuel consumption for operators. –
