irbus’ manufacturing subsidiary Premium AEROTEC in Augsburg, Germany has commenced production of the first Rear Center Tank (RCT) for the Airbus A321XLR. The "first metal cut" – the production of the first machined part for the tank – took place on 25 June 2020. The RCT, which is unique to the new long-range A321XLR, is a permanently installed high-capacity fuel tank that makes maximum volumetric use of the aircraft’s lower fuselage. The RCT structure, which is integrated in fuselage Sections 15 and 17, is located behind the main landing gear bay and holds up to 12,900 litres – which is more fuel than several optional Additional Centre Tanks (ACTs) combined could hold previously in the A321 Family. Moreover, since the RCT takes up less space in the cargo hold, it frees-up underfloor volume for additional cargo and baggage on long range routes of up to an unprecedented 4,700nm.
Premium AEROTEC, which was commissioned by Airbus in September 2019 to manufacture the RCT, will complete the structure’s sub-assembly over the next few months at its factory in Augsburg, Germany. This phase involves production of the other RCT parts, followed by structural assembly, systems equipping and testing prior to delivery to Airbus’ major component assembly (MCA) facility in Hamburg early next year, where the tank will be integrated into the aircraft’s rear fuselage.
In addition to the dedicated RCT, other key changes for the A321XLR include a modified landing gear for an increased maximum take-off weight (MTOW) of 101 metric tonnes, uprated brakes, and an optimised wing trailing-edge flap configuration to preserve the same take-off performance and engine thrust requirements as today’s A321neo. By early 2020, the first long-lead components for the initial A321XLR flight-test aircraft were already in production – including the main landing gear forgings by Safran and the first parts for the centre wingbox by Airbus in Nantes.
The A321XLR, the next evolutionary step in Airbus’ single-aisle family, has been designed to maximise overall commonality with the rest of the A320neo Family, while introducing minimal changes needed to give the aircraft an Xtra Long Range with increased revenue payload and best travel experience with the Airspace cabin. To date, 24 customers have ordered a total of more than 450 A321XLRs, validating the market need for the unique capabilities offered by this aircraft. Flight-testing is due to start in 2022, and service entry from 2023. The A321XLR will provide airlines with a range of up to 4,700nm and a 30% lower fuel burn and CO2 emissions per seat compared with previous-generation competitor aircraft.
