在新一代大型涡扇发动机即将随波音777投入航线运营之际,世界各大发动机制造商开始把注意力放在为下一代大型民用运输机提供动力装置上。预计,超大型飞机(VLA)可载客600～800人,航程达14800公里,最大起飞总重为365～455吨。VLA的研制要耗资150亿美元,这意味着要售出500架以上VLA才能做到有利可图。罗-罗公司的有关人士认为,今后肯定需要比现有波音747大的飞机以提高航空公司的营运效益。这主要是因为根据工业界分
As a new generation of large turbofan engines is coming on stream with Boeing 777, major engine manufacturers in the world are beginning to focus on powering the next generation of large civilian transport aircraft. Expected, VLA can carry 600 ~ 800 passengers, voyage of up to 14,800 km, the maximum take-off weight of 365 ~ 455 tons. The development of VLA will cost 15 billion U.S. dollars, which means that it will be profitable to sell more than 500 VLAs. Lo-Luo company’s stakeholders believe that in the future will certainly need more than the existing Boeing 747 aircraft to improve airlines operating efficiency. This is mainly due to industry points
