层流技术是航空领域的关键技术之一，在经济和生态方面都有很大的改善。本文介绍了自然层流发动机短舱的气动设计方法，以及随后通过亚音速运输机的飞行试验对设计质量的验证。空气动力学设计是在欧洲合作计划的框架内对Eight试验自然层流发动机舱的贡献。参加该方案的有航空发动机制造商罗尔斯·罗伊斯公司和MTU公司以及德国航天中心空气动力学设计研究所。发动机舱的制造由Hurel-Dubois（UK）Ltd.负责，仪器的某些部件由牛津大学提供和操作。飞行试验的目的除了验证短舱的空气动力学设计外，主要目的是获得NLF短舱操作方面的实际经验。在1992年9月开始的第一系列飞行试验中，飞行试验结果证实了所使用的空气动力设计工具的适用性。(C)爱思唯尔，巴黎。
The laminar flow technology is one of the key technologies in aeronautics offering substantial improvements in the areas of economy and ecology. This paper describes the aerodynamic design methodology for a natural laminar how (NLF) nacelle and the subsequent verification of the design quality by flight tests with a subsonic transport aircraft. The aerodynamic design was a contribution within the framework of a European collaborative programme to Eight test a natural laminar flow nacelle. The participants in this programme were the aero-engine manufacturers Rolls Royce and MTU as well as the Institute for Design Aerodynamics of the DLR. The nacelle manufacture was undertaken by Hurel-Dubois (UK) Ltd. and some components of instrumentation were provided and operated by the University of Oxford. The flight trials, apart from having the goal of validating the aerodynamic design of the nacelle, had the major objective of obtaining realistic experience with the operational aspects of the NLF nacelle. In the first series of flight trials, which began in September 1992, the flight test results confirmed the suitability of the aerodynamic design tools used. (C) Elsevier, Paris.
