Abstract

Airlines and aircraft manufacturers are forecasting significant incerases in passenger traffic over the next 20 years (1), (2) but it is becoming increasingly apparent that, given a future scenario of increasing fuel costs and environmental controls, this is unlikely to be sustainable unless aircraft become more efficient and environmentally friendly than those in service today.

Hybrid Laminar Flow (HLF) offers a significant contribution towards any overall efficiency improvement but requires relatively complex structures and systems leading to increases in weight, cost and maintenance. Since HLF has never been applied on a production basis, no mature manufacturing solution has evolved for the associated structure or systems. This paper reviews the requirements for HLF strutures and the progress made towards production solutions. It also recognises that the optimum structure may be influenced by the relative importance of fuel saving (or emissions reduction) compared with operating cost reductions.

朝着理想的层流结构努力
航空公司和飞机制造商预测,未来20年的客运量将显著增加(1),(2),但越来越明显的是,考虑到未来燃料成本和环境控制的增加,这种情况不太可能持续下去,除非飞机比目前的飞机更高效、更环保。混合层流技术(Hybrid Laminar Flow,简称HLF)为提高整体效率做出了重大贡献,但其结构和系统相对复杂,导致重量、成本和维护成本增加。由于HLF从未在生产基础上应用,因此没有成熟的制造解决方案用于相关的结构或系统。本文回顾了对HLF结构的要求以及在生产解决方案方面取得的进展。它还认识到,与降低运营成本相比,节省燃料(或减少排放)的相对重要性可能会影响最佳结构。
