The Airbus A350 already has extra 3D printed components than another civil airliner.
And that listing of AM parts will develop additional shortly due to German firm Liebherr-Aerospace Lindenberg GmbH, who might be manufacturing a posh titanium part for the plane.
Liebherr has been chosen to provide the decrease cargo door actuator and valve for the A350 additional huge physique passenger plane.
It’s one among many ongoing initiatives between Liebherr’s middle of competence and Airbus.
Liebherr focuses on flight management methods, touchdown gears, gears, gearboxes and electronics, and is collaborating intensively with Airbus within the growth of additive layer manufactured parts.
Liebherr has {hardware} put in on all Airbus plane and has supplied AM parts for the A350 earlier than.
That is nice information for us, as a result of we don’t have any pictures of the brand new 3D printed cargo door actuator, so let’s take a look at among the earlier AM components that Liebherr has manufactured for the A350.
They had been the primary firm to supply certified AM titanium components to Airbus, after they delivered a proximity sensor bracket for the A350 nostril touchdown gear. You may see a comparability of the unique half versus the AM half within the graphic beneath.
In that case, the bracket was redesigned to be 100% stiffer and 29% lighter than the unique, and even added additional options, presumably decreasing half rely from different adjoining components within the meeting.
One of many subsequent components printed by Liebherr for the A350 was the spoiler actuator valve block.
This was printed with an EOS printer and was the primary AM main flight management hydraulic part flown on an Airbus plane. A spoiler actuator strikes the spoiler to the specified place to lower the elevate of the airplane.
Sometimes this half would begin from a solid block of titanium, and could be machined, completed and assembled. Through the use of AM the brand new model was 35 % lighter and constituted of fewer components. It was potential to combine 10 practical components into the brand new valve block.
Lighter and extra environment friendly equals much less gas and glad airline operators.
“3D printing is a expertise that’s over 20 years outdated, however has lately skilled an unlimited growth and affords thrilling prospects, notably in plane engineering,” stated Alexander Altmann, head of the Additive Manufacturing / Analysis & Know-how challenge at Liebherr.
“Airbus lately flew one among our 3D printed spoiler actuator valve blocks on a flight check A380. The primary-ever 3D printed main flight management hydraulic part flown on an Airbus plane! The valve block affords the identical efficiency as the traditional valve block constituted of a titanium forging, however it’s 35% lighter in weight.”
Eventually rely (2015) the Airbus A350 had over 1000 additive manufactured components on every plane. We do not know how massive that quantity is immediately, however anticipate it to get larger.
