底部带姿控发动机的飞行器气动力计算

本文提出了一种新的底部带姿控发动机的飞行器气动力计算方法。该方法将S.C.Ward的工程方法与作者近年来发展起来的底部带横向喷流的超音速强干扰流场的轴对称数值模拟方法有机地结合在一起,能给出喷流产生的包括直接、间接两部分在内的总推力和附加的俯仰力矩系数和偏航力矩系数。与无喷射的情形相比,底部阻力系数C_D减小了。

British and German initiatives for defence cooperation: the Joint Expeditionary Force and the Framework Nations Concept

At NATO’s 2014 Wales Summit, the UK and Germany unveiled two new initiatives for European defence cooperation, known, respectively, as the Joint Expeditionary Force (JEF) and the Framework Nations Concept (FNC). Both were the result of economic pressures and the need to exercise intra-alliance leadership, but they represented very different approaches to cooperation. The JEF was to be a UK-led contingency force for short-notice operations, selectively incorporating forces from allies and partners. The FNC sought to coordinate capability development between groups of allies, centred on larger framework nations, to develop coherent capability-clusters available to meet NATO’s force requirements. The common denominator and novelty of the initiatives was the building of forces and capabilities multinationally by having major states act as framework nations for groups of smaller allies. The UK and Germany have ownership and continue to provide leadership to these initiatives. This is one key reason why they continue to evolve to accommodate changing circumstances and are likely to endure.     

Turkey’s strategic choice: buy or make weapons?

Turkey has been investing in its national defence industrial base since the 1980s. As with other developing countries, Turkey’s motivations for investing in national defence industries can be boiled down to the pursuit of defence autarky, economic benefits and international prestige. However, after 40 years of investment, Turkey is unable to reach the primary goals of defence industrialisation. We argue that three factors are important to understanding Turkey’s persistence in these primary goals. First, Turkey believes that there is an overall improvement in its defence industrial capabilities and the goal of autarky is still reachable. Second, increased defence exports support the belief that Turkish defence industries have become sustainable and the trend will continue in the future. The third reason, perhaps most important of all, has to do with the domestic political gains of defence industrialisation: the AKP uses defence industry and indigenous weapon systems for prestige and, therefore, garners broader support.     

Perspectives for the development of key industrial capabilities for Canada’s defence sector

With the Canada First Defence Strategy, Canada has put forth a major opportunity to reconcile national security imperatives and industrial policy. The Jenkins Report (2013) set out to examine ways to use that procurement effort to foster key industrial capabilities (KICs) that would put the Canadian defence industry at an advantage both nationally and internationally. The Canadian defence industry should then develop highly focused capabilities with a view to moving up global value chains. As such, KICs that hold the best potential should be selected. They should be sustained through a range of strategies that are however contingent on the elimination of policy gaps. This leads to a balancing act between the need to control intellectual property assets versus accessing them in a world where national boundaries are eroded. Canada’s industry should target opportunities outside North America while continuing to focus on better integration with the North American industry.     

The Reluctant Atlanticist: France’s Security and Defence Policy in a Transatlantic Context

ABSTRACT

This article introduces the key tenets of French foreign and security policy during the Cold War, and illustrates the deep challenges to the French consensus raised by the emergence of a unipolar system. There is a growing gap between the rhetoric of French security policy, emphasizing ‘autonomy’ and ‘sovereignty’ out of habit from the Cold War, and the actual security practices showing a gradual embedding within the transatlantic security structures. In the absence of a new transpartisan grand narrative relevant for the contemporary international system, such embedding is easily portrayed in France as a ‘treason’ from a romanticized Gaullist foreign policy.
