    • PROBLEM TO BE SOLVED: To simplify washing of an aero engine, to shorten time for wash operation, and to reduce a labour requirement.SOLUTION: This system for washing a gas turbine engine (1) includes: a spray device (33; 90) including a nozzle (54) adapted to inject liquid into the inlet (310) of the engine during the washing operation; a wash unit (31, 35) adapted to distribute the liquid to the spray device; and a positioning device (34) adapted to move the spray device in three dimensions, thereby enabling a positioning of the spray device in a washing operation position in the three dimensions relative the inlet without any contact between the spray device and the engine. The spray device includes a central axis (501), a central body (50; 91), and a pipe (61) having the nozzle (54) adapted to inject liquid into the engine during the washing operation. The spray device is arranged in the washing operation position relative the engine inlet without any contact between the spray device and at least one pipe and inlet cowling, and the central axis is aligned with the engine shaft when the spray device is in the washing operation position.
    • 要解决的问题:为了简化航空发动机的清洗,缩短洗涤时间,并减少劳动力需求。解决方案:用于清洗燃气涡轮发动机(1)的系统包括:喷射装置(33; 90) 包括适于在洗涤操作期间将液体喷射到发动机的入口(310)中的喷嘴(54) 适于将液体分配到喷雾装置的洗涤单元(31,35); 以及适于在三维空间中移动喷雾装置的定位装置(34),从而能够使喷雾装置相对于入口三维地定位在相对于喷射装置和发动机之间任何接触的三维空间中。 喷射装置包括中心轴线(501),中心体(50; 91)和具有适于在洗涤操作期间将液体注入发动机的喷嘴(54)的管道(61)。 所述喷射装置相对于所述发动机入口布置在所述清洗操作位置,而所述喷射装置与所述至少一个管和入口罩之间没有任何接触,并且当所述喷射装置处于所述洗涤操作位置时所述中心轴与所述发动机轴对准 。
