The story began in 1989 when Boeing embarked on a collaborative project with eight airlines to create a high-capacity, twin-engine aircraft that would bridge the market’s gap. The result was the world’s largest twin-jet aircraft, the Boeing 777-200, which was introduced in 1995 and quickly gained approval from the Federal Aviation Administration (FAA) to fly ETOPS during service entry.
777 系列已经走过了漫长的道路，目前有两代和五种型号可供选择。截至 2022 年 10 月，超过 60 家客户共订购了 2,141 架飞机，并交付了 1,696 架飞机，事实证明它是全球航空公司的热门选择。 2019年，777系列凭借优越的航程和燃油效率被誉为最受欢迎的宽体飞机。在世界上最长的 20 条商业航线中，有一半由 777 运营。
这架飞机将是有史以来最大的双引擎飞机，全长 76 米，采用两舱配置最多可容纳 426 名乘客。凭借新发动机和更大的机翼，777X 有望实现更高的效率、容量和航程。
The 777’s superior performance is in part due to the use of high-performance composite materials, which have replaced metallic structures in many components of the aircraft. The use of composite materials has allowed the 777 to achieve a weight reduction of 20%, without sacrificing mechanical strength.
Gill Corporation (TGC) 在提供制造 777 所需的轻质、高性能材料方面发挥了重要作用。随着每一代 777 都要求进一步减轻重量，TGC 利用材料和技术的进步来满足日益严格的要求。从机舱和货舱地板到货舱内衬、内部标志、储物箱、飞行控制面、发动机短舱、尾锥和防雷解决方案，TGC 一直处于这场革命的前沿。
TGC’s Gillfloor® series is a range of high-strength floor panels made from unidirectional carbon reinforced epoxy facings bonded to honeycomb cores. The floor panels offer a 10-12% weight savings compared to traditional panels, and the latest model, Gillfloor® 4809, provides a weight reduction of 13% to 21% compared to earlier generations.
TGC’s cargo bay liners, interior monuments, and stowage bins are all made of composite materials with honeycomb cores, offering high strength-to-weight ratios and exceptional durability. TGC’s lightning protection products include conductive tapes, lightning protection meshes, and bonding solutions, all of which provide superior protection against lightning strikes and other electrical hazards.
TGC’s contribution to the program has been vital, providing the lightweight, high-performance materials needed to create a next-generation aircraft. With the launch of the 777X, Boeing and The Gill Corporation are once again pushing the boundaries of what’s possible in aviation, paving the way for an even brighter future in air travel.
