First engine wash with carbon dioxide pellets worldwide
Cyclean Dry Ice to be launched shortly
Lufthansa Technik AG has developed a unique procedure to wash engines with dry ice, the solid form of carbon dioxide (CO2). The company has filed several patent applications, which means it can now develop an actual product, which will be called Cyclean Dry Ice. As of 2019, the system will be used alongside the water-based Cyclean® engine wash.
During the new engine wash procedure, dry ice pellets that are only a few millimeters in size are shot into the engine via a mobile blasting system. When they hit the components, the pellets release kinetic energy. Through this energy and the contact with the ice-cold pellets (-78.5 degrees Celsius / -109.3 °F), dirt is dislodged from the components.
The new procedure has many advantages: The carbon dioxide used is a by-product of the oil refinery and fertilizer industries so that no additional carbon dioxide has to be generated. And since the pellets transition fully to a gaseous state, there are no residues to deal with. In addition, the procedure can also be applied at outdoor temperatures below freezing. Engines can thus be washed 365 days a year, even in permafrost regions.
The mobile Cyclean Dry Ice washing system is mounted on a platform with an omnidirectional drive. A height-adjustable scissor lift enables fast and thorough cleaning of all engine types, regardless of their size and height. Since there is no need to fasten any pieces of equipment to the engine or to perform a run-up after the engine has been washed, the time needed for the cleaning process - and thus the ground time - is reduced to just 30 minutes compared with conventional engine washes.
Dirk Deja, project manager at Lufthansa Technik, said: "With this new procedure, Lufthansa Technik will strengthen its leading market position and be the first MRO provider to offer engine washes with dry ice on the market. We are thus making another significant contribution to reducing fuel consumption and carbon dioxide emissions in civil aviation by several hundred thousand tons per year."
MoU with Norwegian for comprehensive CFM56-7B engine services
Total Engine Support (TES®) for Boeing 737-800 fleet Early extension of existing contract
The Norwegian Air Shuttle Group and Lufthansa Technik have signed a Memorandum of Understanding to early extend an existing Total Engine Support (TES®) contract with Lufthansa Technik. The agreement covers all-inclusive services for the CFM56-7B engines powering the airline's current fleet of 115 Boeing 737-800 aircraft.
According to the MoU, Lufthansa Technik will cover all planned and unplanned shop visits for the next five years at its highly dedicated CFM56 engine shop in Hamburg, Germany. The extended agreement will also cover a far-reaching engine lease management. Lufthansa Technik will secure the leasing of spare engines for Norwegian to ensure the availability during peak overhaul periods. The contract will also include the regular employment of Lufthansa Technik's proprietary Cyclean® Engine Wash and on-site services such as the use of the portable device aerotracer.
Lufthansa Technik has been maintaining Norwegian's CFM56-7B engines since the fleet introduction of the Boeing 737-800 in 2008. In addition to the current engine agreement, Lufthansa Technik also supports the 737-800 fleet of the Norwegian Group with a range of other services, including extensive airframe maintenance.
Oerlikon and Lufthansa Technik to jointly accelerate additive manufacturing processes and standards
Oerlikon AM and Lufthansa Technik will jointly establish replicable additive manufacturing (AM) processes and standards for maintenance, repair and overhaul (MRO) applications.
The objective is to guarantee robust and repeatable processes on multiple machines in multiple locations
Oerlikon (SIX: OERL), a leading technology and engineering group, and Lufthansa Technik, a leading provider of maintenace, repair and overhaul (MRO) services for civil aircraft, engines and components, today signed a Memorandum of Understanding (MOU) to establish robust and repeatable processes for additive manufacturing (AM) in the aicraft MRO industry. The partnership is an important step toward the industrialization of AM in the aircraft MRO industry and aims to take advantage of potential flexibility and cost savings in manufacturing, procurement, warehousing and supply chain management.
Oerlikon AM and Lufthansa Technik will build up representative component geometrics. The components will be printed on identical printers in three global locations: Oerlikon AM Charlotte (North Carolina, USA), Oerlikon AM Barleben (Germany) and Lufthansa Technik in Hamburg (Germany). The same process parameters and powder specifications will be used to understand process repeatability. The partnership is for a one-year period and may be extended to other models of printers as more data on manufacturing processes is collected.
