航空女杰耀香江——记空中小姐沈慧芙轶事

本文是现在美国的司徒伟先生向关中人提供信息,由广东省中山图书馆梁惠卿同志查找出来的.关中人不认识作者韦基舜先生,也不清楚他怎样知道有《航空史研究》、《航空女杰》和《中国妇女航空钩沉》等书刊.从文章的第一段来看,作者似并未看过上述书刊,他之所以特别点出来,可能是因为他的文章就近避远,对沈慧芙的空姐经历只字未提之故、沈慧芙是不是中国首位空姐?甚至她是不是空姐?还都不了解,有待于查证.

蓝天探险第一人——访新中国第一个飞机试飞员段祥录

1993年10月26日,我前往北京军区空军“劲松干休所”,专程登门访问了段祥录副军长,他是我在《东北老航校》时的同学,在抗美援朝战场上我们共同执行过“轰炸大和岛”的战斗任务,是比翼齐飞,生死与共的亲密战友.现在,他多年患病,身体虚弱,知我立志要编撰《人民空军之最》的航空历史故事,要将他试飞新中国生产的第一架飞机的事迹编写成历史故事,以激励青少年的爱国主义热忱,他虽身体不适,仍热情地介绍了当年试飞国产雅克—18的详细情况.连续说了近两个小时,精神饱满,思路清晰,并表示弄不清以后还可以说.他的革命精神深深地鼓舞着我,同时也把我的思路带回到建国初期全国人民在中国共产党,英明领袖毛主席领导下,齐心协力建设社会主义新中国的沸腾时代.     

有一种情节叫“大话西游”

<正>星爷的《大话西游》以重映的形式再次呈现于大银幕,让我有了一种久违的买票观影的冲动。二十年前,星爷以自己独特的方式向我们讲述了一个关于"西游记"的故事;十二年前,我在学校的电影赏析兴趣小组课堂上,第一次看到了这部电影。《西游记》——一部公认的经典,被人们以各种艺术形式诠释了无数次,却被周星驰颠覆性地解构了,但那时他还没被人尊称为星爷。《大话西游》不再是一个讲述悟空从出生、被驯服到跟随师父降魔取经的神话励志故事,而是反传统地赋予了悟空人性化般的爱情理想。     

游走在心象之间

晴秋人精致,在现如今物质与浮躁的上海不多见。她像三十年代上海知性女人气质得体、典雅。晴秋又是游走于自我色彩中的精灵,一个忠于自己灵魂的画家。她的作品没有沾染浮华之气,在喧嚣市侩的夹缝中还保持着独立的自我品格,她的作品始终流露着她对绘画的那份原始的热情。置身于当今多元陈杂的图像时代,人们总期望着通过画家的作品,去梳理并揣摩他的创作心态,感觉和感受他精神层面的意绪,从而复原出画家的理想、追求、观念和价值。"画如其人",意为作品和作者在气质上的一致,透

Integrated flight control systems: a new paradigm for an old art

The automatic flight control computer was a revolutionary development in the early days of flight, even in its primitive electromechanical form. It evolved into an electronic computing device, starting as an analog computer and maturing into software run on a digital, general-purpose microprocessor. The current accepted industry standard is to use a dedicated microprocessor in its own enclosure for this function that is essentially firewalled from the rest of the systems on the aircraft. This paper will explore the opportunity to integrate the flight control function into an integrated processing platform, which is a robustly partitioned platform that supports multiple functions of dissimilar design assurance levels. This approach provides all of the benefits of an integrated system, while still maintaining the separation provided by a stand-alone unit. The paper will consider both the advantages and disadvantages of this approach. The discussion will describe each of the alternatives in general and then focus specifically on autopilot and flight control functions that have potential for integration. The end goal of the paper is to impress on the reader an understanding of the different alternatives available for autopilot, flight control, and avionics modernization in general. This includes the development of a selection matrix that will assist the reader in making decisions on how best to implement these functions according to criticality and the volatility of their future requirements     

State of art on energy management strategy for hybrid-powered unmanned aerial vehicle

New energy sources such as solar energy and hydrogen energy have been applied to the Unmanned Aerial Vehicle(UAV), which could be formed as the hybrid power sources due to the requirement of miniaturization, lightweight, and environmental protection issue for UAV. Hybrid electrical propulsion technology has been used in UAV and it further enforces this trend for the evolution to the Hybrid-Powered System(HPS). In order to realize long endurance flight mission and improve the energy efficiency of UAV, many researching works are focused on the Energy Management Strategy(EMS) of the HPS with digital simulation, ground demonstration platforms and a few flight tests for the UAV in recent years. energy management strategy, in which off-line or on-line control algorithms acted as the core part, could optimize dynamic electrical power distribution further and directly affect the efficiency and fuel economy of hybrid-powered system onboard.In order to give the guideline for this emerging technology for UAV, this paper presents a review of the topic highlighting energy optimal management strategies of UAV. The characteristics of typical new energy sources applied in UAV are summarized firstly, and then the classification and analysis of the architecture for hybrid power systems in UAV are presented. In the context of new energy sources and configuration of energy system, a comprehensive comparison and analysis for the state of art of EMS are presented, and the various levels of complexity and accuracy of EMS are considered in terms of real time, computational burden and optimization performance based on the optimal control and operational modes of UAV. Finally, the tendency and challenges of energy management strategy applied to the UAV have been forecasted.
