Airbus A350-1000 test aircraft, MSN071,
completed fuel system and engine tests in Cardiff, Wales last week as part of its type certification flight test campaign.
Fuel test engineers from Airbus’ site at Filton, Bristol,
were on hand to support testing of the fuel systems that were
designed in the UK.
The objective of the test is to simulate
operational conditions in hot countries and check how the global fuel
management system and engines behave with hot fuel (over 43°C).
Airbus says that the early results demonstrate that the fuel management
system efficiently handles various fuel densities and
temperatures, as well as fuel flow to engines and between tanks
while airborne offering the best operational performance.
A350-1000 is ready for hot conditions operations from Entry Into
Service later this year.
The A350-1000, just as the -900, has a
simplified fuel system with only three tanks and fewer pumps and
Fuel systems tests are part of
standard tests for all new aircraft and major modifications such
as new engines. The aircraft was fuelled twice a day and then the
flight test team performed a number of required engine and systems
flight tests with hot fuel.
The site at Filton, Bristol is
Airbus’s worldwide centre of expertise for fuel systems design and
testing, which is why these fuel tests for the A350-1000 - as for
all Airbus aircraft such as A320neo, A380, A350-900, and A400M -
have been carried out in the UK.
As well as
having a longer fuselage to accommodate 40 more passengers than
the A350-900, the A350-1000 also features a modified wing
trailing-edge, new six-wheel main landing gears and more powerful
Rolls-Royce Trent XWB-97 engines.
