Space, security in the forefront

The Washington Watch column reports on President Bush's recently announced human space flight program, which includes new policies for returning the shuttle to flight, finishing the International Space Station by 2010, and developing a new space vehicle to return to the Moon; challenges in the airline industry; and selection of a helicopter for use by the President.     

蓝紫色的回忆之旅

6年前一直对于普罗旺斯有着一股美好的憧憬,于是一次买了三本彼得·梅尔所描述的一年四季的普罗旺斯旅游散文集,彼得笔下的普罗旺斯似乎远远超出了一个地域性的代名词,普罗旺斯同时也是一种生活的态度和形式,居住在普罗旺斯的人民像是被自然宠坏了得小孩儿,生活的逍遥自得,其乐融融。他们似乎已经跳跃了都市的繁华的浮躁,抛弃了朝九晚五都市的尘嚣。远离凡尘的当地人民似乎在无形中透露着一种天时地利赋予他们的自傲感。     

An adventure in technology and marketing: a personal account. Tripto the Orient via the Moon

Early in the sixties when President Kennedy announced the goal to land a man on the Moon and return him safely to Earth, there was no way to gauge, accurately and reliably, the millions of pounds of fuel and oxidizer in the proposed rocket. Late in the sixties, when Phillips Petroleum and Marathon Oil contracted to provide large-scale, long term, ocean transport of Liquefied Natural Gas, no system existed to satisfactorily gauge this stream of high value cargoes for commercial transactions. The adventure in solving these related problems led to a worldwide market for LNG Custody Transfer Systems, a successful transfer of technology from a NASA program to commercial use     

小孔辅助射流提高冷效的机理分析

本文采用数值计算手段,模拟普通的圆柱形单孔结构和小孔辅助射流结构在不同吹风比下的流动和换热,侧重通过直观演示气膜孔下游反向对旋涡对（肾形涡）的生成、发展以及相互作用过程,揭示小孔辅助射流改善气膜冷却效果的机理。结果表明：与单孔结构相比,小孔辅助射流结构,由于小孔射流的干涉作用,主孔射流形成的肾形涡的尺度和强度均有较大程度的减小,冷气射流与主流的掺混减弱,对冷气的向上抬升作用减小,避免了冷气穿透主流脱离壁面,大大提高冷效。随着吹风比的增加,与圆柱形单孔相比,气膜冷却效果改善更加明显。     

Automation and Robotics for the Space Station: Recommendations

On January 25, 1984, President Reagan announced a United States program to place a permanent space station in orbit in 1992. The Congressional bill appropriating the funding for this program requires that a significant portion of the program funds be for the development of new automation and robotics technologies not in use on existing spacecraft. To assist it in developing plans to meet this requirement, NASA established an Automation and Robotics Panel in August 1984. This paper presents verbatim the Executive Summary of the Panel's report to NASA. It should be recognized that this report to NASA is advisory only, and that for a variety of reasons, including funding, what is actually implemented will certainly differ in many respects from the recommendations. Nevertheless, the report represents the thinking of a prestigious group of scholars and practitioners in automation and robotics, and many of the recommendations undoubtedly will be implemented. A summary of the NASA recommendations will be published following their official release.     

燃烧室室壁冲击／气膜复合冷却壁温分布研究（二）理论部分

气膜冷却对激波与边界层相互作用影响的数值模拟

针对跨声速平面叶栅中气膜冷却对流场的影响,采用数值模拟的方法,分析了激波和边界层的相互作用及引入气膜冷却之后三者之间的影响。结果表明,由于激波形成的逆压力梯度导致边界层出现分离现象,在引入冷却射流以后被部分抑制,流场细节显示在原分离处新形成了两个方向相反的分离旋涡。保持冷却条件不变,随着孔间距的减小,边界层分离现象被抑制的效果更加明显,平面叶栅热力损失系数逐渐减小。当孔径和孔间距之比达到0.67时,相对于没有引入气膜冷却的情况,热力损失系数降低了13%。冷气流量对射流和主流相互作用流场影响显著,冷气出口局部超声速区域显著增大流场损失,降低冷却效果。     

An overview of infrared thermography techniques used in large wind tunnels

Infrared thermography (IRT) is used at Onera in large facilities for boundary layer visualization and for heat flux assessment. Modern IR cameras and insulating paints enable efficient visualization of the laminar/turbulent transition region. This technique is now applied in large transonic test facilities. Heat flux assessment is one of the main purposes of hypersonic tests. It is done mainly with IRT and dedicated softwares, while sensors as thermocouples are used to check the reliability of IRT. A 1D data reduction method has been developed to provide the heat flux through temperature measurements. It takes into account thickness and curvature effects. The method has been recently improved to be used with steel models covered with an insulating paint, which provides a high emissivity. The temperature film is converted into a heat flux film, which is be used to extract the useful information. This requires image processing tools that relate every pixel to a point on the model. A new application of IRT is going on in the Onera's high enthalpy hypersonic wind tunnel F4. The camera is used in single-line scan mode because of the short duration of the run. The main difficulty comes from the flow, which is not transparent. The first trial to cope with this kind of optical pollution is encouraging.     

基于异频扰动和CFD技术的滑动轴承动力特性系数识别方法

目前CFD技术已广泛应用于滑动轴承的数值仿真中,但还存在两个问题,相对于传统的通过求解Reynolds方程获得流体压力场和油膜力的方法,如何通过CFD计算结果来识别得到动力特性系数,以及CFD方法误差有多大。针对这些问题,本文基于同幅异频位移激励技术,同时充分考虑惯性力、刚度、阻尼交叉项等因素给出了一套适用于挤压油膜阻尼器、可倾瓦轴承、固定瓦轴承等多种模型的动力特性识别方法,应用该方法可以一次性识别出油膜的动力特性系数。通过滑动轴承算例与短圆瓦轴承刚度阻尼理论解进行对比,验证了该方法的准确性。     

二氧化碳射流下孔型对气膜冷却特性影响的实验研究(英文)

This article presents the data about heat transfer coefficient ratios, film cooling effectiveness and heat loads for the injection through cylindrical holes, 3-in-1 holes and fanned holes in order to characterize the film cooling performance downstream of a row of holes with 45° inclination and 3 hole spacing apart. The trip wire is placed upstream at a distance of 10 times diameter of the cooling hole from the hole center to keep mainstream fully turbulent. Both inlet and outlet of 3-in-1 holes have a 15° lateral expansion. The outlet of fanned holes has a lateral expansion. CO2 is applied for secondary injection to obtain a density ratio of 1.5. Momentum flux ratio varies from 1 to 4. The results indicate that the increased momentum flux ratio significantly increases heat transfer coefficient and slightly improve film cooling effectiveness for the injection through cylindrical holes. A weak dependence of heat transfer coefficient and film cooling effectiveness, respectively, on momentum flux ratio has been identified for the injection through 3-in-1 holes. The in- crease of the momentum flux ratio decreases heat transfer coefficient and significantly increases film cooling effectiveness for the injection through fanned holes. In terms of the film cooling performance, the fanned holes are the best while the cylindrical holes are the worst among the three hole shapes under study.
