Definitions
- the invention relates to a method for maintenance, in particular dismantling, of gas turbines, i.e. Aircraft engines or stationary gas turbines, according to the preamble of claim 1 and a system for maintenance, in particular dismantling, of gas turbines, i.e. Aircraft engines or stationary gas turbines, according to the preamble of claim 10.
- the maintenance or servicing of gas turbines, in particular aircraft engines, plays a decisive role in determining the direct operating costs of an aircraft.
- About 30% of the direct operating costs of an aircraft are assigned to the aircraft engines, with about a third of the operating costs relating to the engines being attributable to the maintenance of the aircraft engines.
- the costs for the maintenance of aircraft engines account for approximately 10% of the total direct operating costs of an aircraft. It follows directly from this that efficient and cost-effective maintenance or servicing of aircraft engines is of crucial importance for airlines. The same applies to stationary gas turbines.
- the present invention is based on the problem of creating a novel method for maintenance, in particular dismantling, of gas turbines, in particular aircraft engines, and a corresponding system.
- a gas turbine is inserted into a first device which is at least largely sealed against detergent leakage before disassembly, is cleaned in the first device and is removed from the first device after cleaning.
- the cleaned aircraft engine is then taken to disassembly. This ensures that contaminants and lubricants or the like accessible from the outside are removed from the aircraft engine before the dismantling begins. This has a positive impact on the entire maintenance process.
- the sealing against detergent leakage prevents contamination of other areas outside the first device.
- a gas turbine to be serviced is positioned in the first device for cleaning. After cleaning, the same is transferred from the first device to a second device, which is used for dismantling the gas turbine, by changing a conveying device. This ensures that the contaminants and lubricants removed during the cleaning of the gas turbine do not reach the area of the second device which serves to dismantle the gas turbine.
- a system according to the invention with a first device for cleaning an aircraft engine and a second device for dismantling the same, together with an aircraft engine arranged outside the first device and positioned on a forklift in a schematic plan view;
- FIG. 2 the arrangement according to FIG. 1, the aircraft engine being positioned by the forklift in the first device;
- FIG. 7 the arrangement according to FIG. 6, the cleaned aircraft engine being positioned on a conveyor device downstream of the first device.
- 1 to 7 show a system according to the invention for the maintenance, in particular dismantling, of gas turbines using the example of an aircraft engine.
- the present invention relates to the cleaning and subsequent dismantling of an aircraft engine during the maintenance or repair of the same.
- a system for the maintenance of aircraft engines can accordingly comprise further devices which are not shown in FIGS. 1 to 7 for a simplified illustration of the invention.
- FIG. 1 shows a system for the maintenance or servicing or repair of an aircraft engine.
- the system comprises a first device 10 for cleaning an aircraft engine and a second device 11 downstream of the first device 10 for dismantling the aircraft engine.
- an aircraft engine 12 to be maintained is positioned outside the system or first device 10 and second device 11. 1 shows that the aircraft engine 12 to be serviced is arranged in a transport frame 13, which is positioned together with the aircraft engine 12 on a forklift 14.
- a first conveyor device 15 is assigned to the first device 10 for cleaning the aircraft engine 12.
- the first conveyor device 15 is designed as a conveyor crane.
- a second conveyor 16 is assigned to the second device 11 for dismantling the aircraft engine 12. With the aid of the second conveyor device 16, the aircraft engine 12 is moved through a plurality of workstations of the second device 11 arranged one behind the other for dismantling the aircraft engine 12. 1 to 7 only show a first work station 17 of the second device 11 for dismantling the aircraft engine 12 or a corresponding section from the second conveyor 16. The first work station 17 of the second device 11 for dismantling the aircraft engine 12 connects to the first device 10 for cleaning the aircraft engine 12.
- the device 10 for cleaning the aircraft engine is designed as a washroom or washroom, the first conveying device 15 designed as a conveyor crane being positioned within the washroom.
- the first conveyor device 15 or the conveyor crane essentially has two spaced-apart units Longitudinal beams 18, 19 running parallel to one another.
- the two longitudinal beams 18, 19 extend on the one hand over the entire width of the first device 10 for cleaning the aircraft engine 12 and on the other hand also extend into the area of the first work station 17 of the second device for dismantling the aircraft engine 12.
- the first conveyor 15, which is designed as a conveyor crane comprises two cross beams 20, 21.
- the cross beams 20, 21 can be moved along the longitudinal beams 18, 19.
- a strut 22 acts on the cross members 20, 21 and can be moved over the entire area of the cross members 20, 21 and thus between the two longitudinal members 18, 19.
- An adapter 23 for receiving an aircraft engine is fastened to the strut 22, the adapter 23 being able to be moved upward or downward relative to the strut 22.
- the relative movement of the cross members 20, 21 relative to the longitudinal members 18, 19, the relative movement of the strut 22 relative to the cross members 20, 21 and the relative movement of the adapter 23 allow a three-dimensional movement of an aircraft engine 12 positioned in the adapter 23.
- the adapter 23 is of this type designed that it can accommodate a variety of different aircraft engines 12.
- the aircraft engines are series engines and " familiar to the specialist addressed here.
- the aircraft engine 12 is now positioned in a first step (see FIG. 2) using the forklift 14 in the first device 10 designed as a washing hall.
- a side door 24 is opened so that the forklift 14 can move the aircraft engine 12 received by the transport frame 13 into the first device 10 and position it below the first conveyor device 15 designed as a conveyor crane.
- the aircraft engine 12 to be serviced or repaired is received by the adapter 23 of the first conveyor device 15.
- the forklift 14 is then moved together with the transport frame 13 out of the first device 10 designed as a washing hall and the door 24 is closed again.
- the cleaning of the aircraft engine 12 then begins. 4 shows that an operator 25 blasts or sprays the aircraft engine 12 with a cleaning agent. Before that, the operator drains liquids and lubricant or the like from the aircraft engine 12.
- the operator 25 stands on the floor of the washing hall and accordingly cleans the aircraft engine 12 from below or from the side. Since the aircraft engine 12 is suspended from the first conveyor 15 designed as a conveyor crane, the aircraft engine 12 is freely accessible when it is cleaned. It can therefore be cleaned from all sides.
- the operator 25 climbs onto a car 26 arranged within the first device 10. This is shown in FIG. 5. As can also be seen in FIG. 5, the aircraft engine 12 is moved back and forth along the cross struts 20, 21 for thorough cleaning thereof. This ensures that the operator 25 can clean the aircraft engine 12 from all sides and accordingly all areas of the aircraft engine 12 to be cleaned are easily accessible.
- the first device 10 is at least largely sealed against detergent leakage.
- FIG. 6 shows that the aircraft engine 12 is moved into the area of the first work station 17 of the second device 11 for dismantling the aircraft engine 12 by relative displacement of the cross members 20, 21 along the longitudinal members 18, 19.
- FIG. 7 after the aircraft engine 12 has been cleaned, the same is parked in the area of the first work station 17 and accordingly transferred from the first conveyor device 15 to the second conveyor device 16, which then the aircraft engine 12 to be serviced or repaired for disassembly by several A series of workstations of the second device 11 moved one behind the other, only the first workstation 17 being shown in FIGS. 1 to 7.
- the device 10 for cleaning the aircraft engine 12 is assigned a conveyor device 15. After cleaning the aircraft engine 12, the cleaned aircraft engine 12 is moved out of the first device 10 with the aid of the first conveying device 15 and fed to the first work station 17 of the second device 11, which is used to dismantle the aircraft engine 12.
- the aircraft engine 12 is parked in the first work station 17 on a second conveyor device 16, the second conveyor device 16 moving the aircraft engine for disassembly through a plurality of work stations arranged one behind the other and connected to the first work station 17.
- the conveying devices are accordingly changed. This ensures that detached contaminants or drained liquids, such as lubricant or the like, do not reach the area of the second conveying device 16 or the work stations of the device 11 for dismantling the aircraft engine 12. The contaminants remain in the area of the first device 10 and the first conveyor device 15.
- a further advantage of the method according to the invention and of the system according to the invention can be seen in the fact that the contaminants are detached from the aircraft engine 12 only in a small, limited space in a maintenance or repair hall. In the other sections of the maintenance or repair hall, an aircraft engine 12 which has already been freed from the coarsest contaminants is dismantled, inspected, repaired and then reassembled.
- the method according to the invention and the system according to the invention are particularly advantageous when the maintenance of the aircraft engine 12 is carried out according to the so-called assembly line principle.
- contamination in the area of the conveyor device which moves the aircraft engine 12 to be disassembled through work stations arranged one behind the other is particularly disadvantageous since the functioning of the conveyor device can be impaired by the contamination.
