防空作战威胁环境及伪装技术 总被引:1,自引:0,他引:1
科索沃和伊拉克战争的实践表明:在高科技条件下的局部战争中,对重点军事目标实施大规模空袭已成为进攻一方的首选作战样式。而军事伪装不但可以降低侦察监视系统的发现和识别概率,还可以降低精确制导武器的命中概率。在分析防空作战威胁环境的基础上,提出了伪装器材在防空作战中的任务,介绍了适合重要军事目标的伪装器材和技术,这些器材和技术可提高重要军事目标的生存能力。 相似文献

天基信息支援的高实效性对测控保障能力提出了严格要求,针对测控保障能力的快速评估问题,提出了一种基于层次分析法的快速评估方法。首先,依据时序和事件逻辑匹配一致性原则,将整个评估流程拆解为天基信息支援对测控需求确定、评估数据收集、制定评估指标和标准、分析评估数据、提供评估反馈和建议5个步骤,并基于拆解步骤项,确定了评估实施流程,设计了评估层级结构模型,提出了评估方法。然后,依据独立性原则确定了评估指标和标准,采用综合赋值法确定了指标权值,得到归一化评估结果,并确定不同标准对应的决策建议。最后,通过实例验证表明,方法能够快速完成测控保障能力评估,并提供对应的合理处置决策建议,可为天基信息支援的辅助决策快速提供有效依据。 相似文献

The aim of this paper is to review the main results of medical support of 78 two-person extravehicular activities (EVAs) which have been conducted in the Mir Space Program. Thirty-six male crewmembers participated in these EVAs. Maximum length of a space walk was equal to 7 h 14 min. The total duration of all space walks reached 717.1 man-hours. The maximum frequency of EVA's execution was 10 per year. Most of the EVAs (67) have been performed at mission elapsed time ranging from 31 to 180 days. The oxygen atmosphere of the Orlan space suit with a pressure of 40 kPa in combination with the normobaric cabin environment and a short (30 min) oxygen prebreathe protocol have minimized the risk of decompression sickness (DCS). There has been no incidence of DCS during performed EVAs. At the peak activity, metabolic rates and heart rates increased up to 9.9-13 kcal/min and 150-174 min-1, respectively. The medical problems have centred on feeling of moderate overcooling during a rest period in a shadow after the high physical loads, episodes with tachycardia accompanied by cardiac rhythm disorders at the moments of emotional stress, pains in the muscles and general fatigue after the end of a hard EVA. All of the EVAs have been completed safely. 相似文献

《Space Policy》2014,30(3):143-145
The human exploration of space is pushing the boundaries of what is technically feasible. The space industry is preparing for the New Space era, the momentum for which will emanate from the commercial human spaceflight sector, and will be buttressed by international solar system exploration endeavours. With many distinctive technical challenges to be overcome, human spaceflight requires that numerous biological and physical systems be examined under exceptional circumstances for progress to be made. To effectively tackle such an undertaking significant intra- and international coordination and collaboration is required. Space life and biomedical science research and development (R & D) will support the Global Exploration Roadmap (GER) by enabling humans to ‘endure’ the extreme activity that is long duration human spaceflight. In so doing the field will discover solutions to some of our most difficult human health issues, and as a consequence benefit society as a whole. This space-specific R&D will drive a significant amount of terrestrial biomedical research and as a result the international community will not only gain benefits in the form of improved healthcare in space and on Earth, but also through the growth of its science base and industry. 相似文献

Future space systems, such as Columbus, the planned European contribution to the International Space Station, offer ample possibilities for microgravity research and application. These new opportunities require adequate user support on ground and novel operational concepts in order to ensure an effective utilization. Extensive experience in microgravity user support has been accumulated at DFVLR during the past Spacelab 1 and D1 missions. Based on this work, a Microgravity User Support Centre (MUSC) has been built and is active for the forthcoming EURECA-A1 and D2 missions, to form an integrated support centre for the disciplines life sciences and material sciences in the Space Station era. The objective of the user support at MUSC is to achieve:
- • easy access to space experiments for scientific and commercial users,
- • efficient preparation of experiments,
- • optimum use of valuable microgravity experimentation time,
- • cost reduction by concentration of experience.

The literature on the history of spaceflight has depicted the early 1950s Collier’s articles mostly as a forerunner to the peaceful and scientific exploration of space. Yet the centerpiece of Wernher von Braun's plan was a manned space station that would serve as reconnaissance platform and orbiting battle station for achieving “space superiority” over the USSR. One its roles could be the launching of nuclear missiles. When challenged as to the station's defensibility, von Braun even posited pre-emptive atomic strikes from space as a response to the development of a hostile anti-satellite capability. 相似文献
