摘要

Conventional understanding of flight in aerospace depends primarily on the application of Newton's laws in the design of components providing propulsive and lifting forces. This reality has given incredible advances in capability during nearly a century of endeavour. But this century of achievement was preceded by millennia of speculation, literary fantasies, some tentative scientific proposals and brave practical attempts of how manned flight might be attained. However, the coming of reality did not stop the aerial speculation which has continued over the last century with various doubtful claims that have disguised an underlying seriousness seeking for alternative means of accomplishing aeronautical ambitions. Recently, three professional programmes have emerged, directed to discovering such new ways of propulsion, viz., the NASA Breakthrough Propulsion Physics programme, the BAE SYSTEMS Project Greenglow and work at ESA. The author has followed these novel developments for over half a century and is now a consultant to the BAE SYSTEMS programme. BAE SYSTEMS monitors many evolving scientific and technical advances to seek competitive advantages for its products and pays appropriate attention to the most promising solutions. Some of these are correctly described as breakthroughs and in the speculative field of advanced propulsion it seeks advice on the truth or falsehood of the many quantitative claims that have been published. The primary task is to design radically new aeronautical systems based on new physical principles. This paper sets out this strategy which has the following logic: 1. to account for previous claims, patents and investigations and assess their validity, 2. make scientific experiments of new phenomena and generate theories, 3. propose radically new ways (engines) of providing aeronautical forces, 4. assess whether any of these imaginary engines could improve aerospace performance, 5. if so, how significant would the improvement be? 6. it appears that one solution offers superb improvement, globally, for over a century ahead, 7. hence, it is well worth the effort to realise this in practice, 8. one of the proposed engines is in sequence with previous transport systems, 9. the best way forward is serendipitous collaboration with advanced thinkers in physics, and 10. Project Greenglow links new physics with novel engines and global transport performance by means of evolving techniques used in novel ways. This process, described in this paper, is essentially 'project-led research' (sometimes called 'focussed search'), in which theoretical possibilities are subjected to the classical process of conjecture and refutation, also employed in a previous paper published in this journal, viz., 'Global issues affecting aeronautics' (Prog. Aerosp. Sci. 1999; 35: 413). There is an important distinction between the UK programme and others, i.e., the inclusion of aeronautics as well as spaceflight, whereas the others deal exclusively with spaceflight.

Greenglow项目通过以新颖方式使用的不断发展的技术,将新物理学与新颖的引擎和全球运输性能联系起来。本文所描述的这一过程本质上是“项目主导的研究”(有时称为“聚焦搜索”),其中理论可能性受到经典的猜想和反驳过程的影响,该过程也在本刊发表的先前论文中得到了应用。 ,即“影响航空的全球性问题”(Prog。Aerosp。Sci。1999; 35:413)。英国计划与其他计划之间有一个重要的区别,即将航空和航天纳入其中,而其他计划仅涉及航天。
