Together with Lufthansa Cargo, Lufthansa Technik AG has reached another important milestone in its preparations for the entry into service of the Airbus A350 in Lufthansa German Airlines’s fleet.
In a test carried out in Frankfurt under real-life conditions, a Trent XWB aircraft engine provided by Rolls-Royce was loaded into a Boeing 777F. This successful loading trial means that now the seamless logistics of providing spare engines via air freight are assured.
When prepared for loading, the engine and its transport stand weigh 18 tons. The engine weighs 7 tons (dry weight) and is 5m long. The fan is 3m in diameter. As a result, the engine could only be transported via special flight with an Antonov An-124, an Airbus Beluga or a Boeing C-17. As an alternative, Rolls-Royce developed a completely new type of transport stand upon which the engine can be placed and divided into two large modules.
On this split engine stand, the large-volume fan can be separated from the rest of the engine within a single day. The individual modules are then optimally prepared for transport together with the other tools required for engine replacement, and can then be loaded. The unit that results from this approach can also be transported in freighters from the Boeing 747 and 777 aircraft families.
Lufthansa Cargo currently has five Boeing 777 freighters in its fleet. As part of the test, the company had to demonstrate that the transport conditions required by Boeing could actually be met in practice.
“Months of planning preceded the test,” explained Ralf Henker, responsible for Supply Chain Management in Aircraft Maintenance at Lufthansa Technik. “Without the partnership and cooperation of our colleagues at Rolls-Royce and Lufthansa Cargo, we would not currently be able to ensure that we can supply every destination airport of the new fleet with a replacement engine if necessary. Every move we make has to fit, and every wheel of the logistics chain needs to mesh optimally with all the others.”
“Over the last four months, we developed a detailed loading and rigging plan based on our experience with other capital goods that are similarly sensitive and yet difficult to handle,” said Harald Mueller, responsible for aircraft handling – competence and quality assurance, at Lufthansa Cargo. “It’s great to see that it works in practice exactly the way we envisioned it.”
For some time now, Lufthansa Technik has supported a variety of A350 operators in the areas of component supply and aircraft maintenance. More than 800 aircraft of the A350 type have been ordered from Airbus to date. The Rolls-Royce Trent XWB is the world’s most efficient large civil aero engine and the exclusive engine option for the A350.
