美国在战略导弹设计试验工作中怎样缩短研制周期

前言战略导弹的“研制周期”不能只理解成一个“时间”概念。纵观美国战略导弹的发展过程,可以看出对研制周期的要求,主要取决于国家战略的需要。随着科学技术的飞速发展,敌情态势的不断变化,如果战略导弹的研制周期过长,那么,花费大量人力、物力研制出来的导弹可能会     

2000年前固体推进剂的发展趋势

固体推进剂的发展趋势与战术和战略导弹的发展有密切关系。战略导弹对推进剂的要求就战略导弹而言,研究推进剂的比冲和密度比冲是十分必要的,这项研究工作应与降低结构系数的其它技术(如采用高强度比的纤维缠绕壳体和先进的喷管和防热层材料)和核弹头的小型化研究相配合。装药比冲提高以后,可以针对不同任务,进行灵活的设计和使用。例如:     

美俄新一代战略导弹技术分析

美国和俄罗斯的新一代战略导弹是指两国准备在2010年以后乃至2020年以后作战部署的战略导弹。美俄两国发展新一代战略导弹的目标虽然都是为了长期保持战略威慑,但美国在保持核威慑的同时,还注重非核打击的战略威慑,而俄罗斯则更强调其有效对抗导弹防御系统。     

美国进行弹头试验的小型试验弹

美国试验导弹是其战略导弹发展到一定阶段的必然产物,而试验导弹对美国战略导弹的发展又起了重大的作用。从美国战略进攻导弹的研制进程表明,六十年代初之前,它的研制重点是导弹的运载系统。在导弹的运载系统问题基本解决之后,从六十年代初起就逐渐把重点转移到再入系统,即弹头系统方面,目的

固体火箭发动机推力终止方法——熄火述评

前言第二次世界大战后,随着世界航天工业的发展,固体火箭发动机从战术武器的推进器逐渐成为战略导弹的发动机及某些宇宙飞行器的动力装置是经过解决各种技术难点而逐步应用的。其中推力终止作为一种单项技术,在发动机的研制过程中也不断地发展和日益完善。目前,世界上多数弹道式导弹的末级固体火箭发动机推力终止是依靠装置于发动机前封     

廊坊市构建文化强市战略的实施路径研究

近年来，廊坊市高度重视文化产业发展，把文化产业确立为影响廊坊未来发展的战略产业，作为构建现代产业体系的重要内容，先后出台了一系列政策措施，廊坊取得了前所未有的成绩。虽然廊坊市文化的发展优势得天独厚且已初具规模，但文化缺乏战略性管理、资金短缺、竞争力不强等问题制约着廊坊市文化的进一步跨越发展，如何构建和完善文化强市战略目标，如何发挥文化对经济的强劲作用，这对廊坊经济稳步、可持续发展具有十分重要的现实意义。     

印度“烈火”弹道导弹突防技术性能分析

Agni在印度语中意为"烈火",也是印度一种战略弹道导弹的代号."烈火"导弹家族一直被认为是印度战略核威慑的中流砥柱,通过改进、改型,其运载能力、射程和突防能力在不断提高.重点对"烈火"系列导弹突防技术性能进行分析讨论.     

A new strategic revolution?

Professor Freedman examines the argument that, with the claimed potential of ballistic missile defence deriving from SDI, there has been a strategic revolution in favour of the defence. He argues that such a revolution will only come despite technological trends and not because of them, ie from building an entirely new strategic relationship with the active cooperation of the USSR, and concludes that the strident advocacy of strategic defensive systems allows the opportunity of avoiding the real dilemmas that confront us in the nuclear age by pretending that there is a technological way out.     

Discovering the basic strategic orientation of big space agencies

The aim of this paper is to identify the basic strategic orientations of some of the world's main space agencies. This study focuses on the Brazilian, French, European, Japanese, Indian and Russian agencies. Basic strategic orientations indicate the real space exploration objectives of large countries. This is useful because there are some ambiguous areas in the formal strategic documents published by these agencies. The results highlight the common objectives of the agencies studied, which is to have an important role in international political leadership even considering the specific objectives related to the economic and social contexts of the individual countries.     

美国典型高超飞行器项目研发及启示

简要回顾了美国典型高超声速飞行器项目及其动力系统发展的历程,分析了其发展的态势、经验和教训。美国始终将高超声速技术作为航空航天事业发展的重要领域,高超声速飞行器和动力技术方案与国家战略及应用背景密切相关。为了降低技术风险,采取了多方案并行的研发模式。高超声速技术的研发应充分重视顶层设计,注重技术的继承性,发挥不同单位的技术优势,加强基础研究、关键技术攻关和实验设施建设。     

International space launch notification and data exchange

As missile and space launch technology continue to proliferate around the world, nations will benefit from increased transparency to mitigate the potentially strategic consequences of early warning false alarms or misinterpretations. Previous false alarms and risk mitigation steps taken by the United States and the former Soviet Union and Russia are examined. Two pre-launch notification initiatives, the bilateral US/Russia Joint Data Exchange Center and the multilateral Hague Code of Conduct, offer means to further build confidence among spacefaring nations and enhance strategic stability. Pragmatic recommendations are offered to strengthen the emerging pre-launch notification regime.     

Understanding strategic decision making in the context of international space activities

This paper argues that a better understanding of strategic decision making processes in different space agencies is relevant to the successful carrying out of international cooperative undertakings in space and that this kind of information should be taken into account when decisions are to be made on engaging in a new partnership. In this context, the paper provides a general framework for the study of strategic decision making in space organisations, with particular emphasis on the influence of culture. Additionally, it offers practical examples of how differences in policy priorities, decision making environments and practices amongst space organisations can affect international cooperative endeavours. A particular concern is with the role of national and corporate cultures in creating and reflecting differences between space agencies. In order to gather information on strategic decision making processes in the space sector, a series of 30 interviews was conducted with top decision makers from NASA, ESA and the space organisations of Brazil, France, Canada, Russia, The Netherlands and the UK.

An alternative strategy process for planning government space programs

This paper presents some thoughts and a methodical approach to the strategic planning of large government projects that takes into account the dynamic development of global problems. Given that an overarching strategic intent is in place and budgetary resources are limited, the methods described herein allow its user to generate and evaluate a set of project proposals according to their individual problem solving potential. In a final step, one is able to select those proposals that are preferable for further planning. Rather than generating detailed programs that are hard to implement in a dynamic environment, the method described herein is only modeling the priorities of different project alternatives. This is less detailed as the plans that result from a classic strategic planning approach, yet is highly usable as a roadmap for implementation. The most important advantage of this approach is its suitability for a dynamic planning with inherent learning cycles that can easily be adapted to dynamic changes in the planning environment. Since change is a well-known phenomenon in space program planning, a paradigm shift towards more flexible and adaptable ways of planning seems to be required.
