Airbus A340 Blade Laminar Flow Wing Demonstrator Makes First Flight

Airbus’ A340 laminar-flow Blade test demonstrator aircraft has made its successful maiden flight for the EU-sponsored Clean Sky Blade project.

The aircraft, dubbed Flight Lab, took off through the Tarbes aerodrome in southern France at local time 11:00, in addition to after a series of successful tests the item landed at Airbus’ facilities in Toulouse Blagnac.

The Blade project – which stands for Breakthrough Laminar Aircraft Demonstrator in Europe – can be tasked with assessing the feasibility of introducing the technology for commercial aviation.

the item aims to improve aviation’s ecological footprint, bringing with the item a 50 per cent reduction of wing friction in addition to up to all 5 per cent lower CO2 emission.

Airbus’ A340 Flight Lab can be the first test aircraft inside the entire world to combine a transonic laminar wing profile which has a true internal primary structure.

On the outside the aircraft can be fitted with two representative transonic laminar outer-wings, while inside the cabin a highly complex specialist flight-test-instrumentation station has been installed.

The extensive modifications to the A340-300 test-bed aircraft took place during the course of a 16-month working party in Tarbes, with the support of numerous industrial partners across Europe.

The first-flight marks the kick-off of the Blade flight-test campaign to explore the wing’s characteristics in flight.

“We began by opening the flight envelope to check of which the aircraft was handling correctly,” explained Airbus flight test engineer, Philippe Seve, who was on board the flight.

“We achieved our objective to fly at the design Mach number, at a reasonable altitude in addition to check everything was fine.

“We also checked of which the FTI was working as expected, to identify further fine-tuning for the next flights.”

inside the run-up to the start of of which flight-testing phase, a tiny team of ten specially trained pilots, test engineers in addition to flight test engineers had prepared because of of which milestone for several months, spending time in a simulator in addition to familiarising themselves with the FTI systems to be installed on the Airbus flight-test aircraft.

Moreover, on equipment installation side, a working party of 70 people performed the FTI installation inside the aircraft, while teams through Bremen, Germany in addition to Broughton, UK worked externally on the outer wings, which has a team through Stade Germany, installing a pod containing infrared cameras on the fin.

On the wings, there are hundreds of points to measure the waviness of the surface to help Airbus’ engineers ascertain its influence on the laminarity – which can be once of which Airbus has used such a testing method on an aircraft.

various other ‘firsts’ are the use of infrared cameras inside the pod to measure wing temperature in addition to the acoustic generator which measures the influence of acoustics on laminarity.

In addition, there can be also an innovative reflectometry system, which measures overall deformation in real-time during flight.

A key goal of Blade can be to be able to measure the tolerances in addition to imperfections which can be present in addition to still sustain laminarity.

To of which end, Airbus will simulate every type of imperfection in a controlled manner, doing sure of which at the end of the campaign the tolerances for building a laminar wing will be fully known.

The flight Lab will perform around 150 flight hours inside the coming months.
