The College of Aeronautics (CoA) at Cranfield University believes that the best way of teaching design is for the students to learn design by doing it, in a structured manner. It also believes in the maxim – “the devil is in the detail” and that a design is only complete when it has been built, flown and certificated. Designers need to be aware of, and experienced in, all of the intermediate stages between concept design and certification. They also need to be taught to function as members of group design teams, because that is the usual way that Industry works. All of these factors led to the establishment of a full-time Masters programme in Aerospace Vehicle Design, the focus of which is the Group Design Project (GDP). This philosophy was proved to be successful over many years and was continued and expanded in the design of the Masters course in Aircraft Engineering – the subject of this paper. This programme is a three-year part-time M.Sc. course, which comprises the same major elements as the full-time course. The students attend lecture modules, perform a piece of individual research and work on a GDP. It was this last element that particularly attracted the launch and predominant customer for the course, the then Military Aircraft Division of British Aerospace (BAe). BAe like the basic philosophy of teaching the design process by placing someone in a project group with an individual responsibility but having to cater for the needs of the group and project as a whole. In February 1995 the Aircraft Engineering course was launched with 15 students, who began the first intake, working on major modifications to the CoA's A1 Aerobatic aircraft, which itself resulted from work of former students. The GDP on the full-time course in Aerospace Vehicle Design concentrates on the preliminary and detail design of a whole aircraft, which has been previously defined in terms of basic geometry, mass, performance, characteristics etc. by staff. However, BAe and Cranfield wished to address a greater extent of the full-design process, as mentioned above. In this way the students would, in the space of three years, be given first-hand experience of a much wider extent of an aerospace project than could ever be the case whilst working on major aircraft projects in a manufacturing company. This paper will give details of the Aircraft Engineering teaching programme and describe the first GDP, a major modification programme and flight of the Cranfield A1 Aerobatic Aircraft. The students were set the task of modifying the existing single seat aircraft to a two-seat configuration with performance similar or better than that of the existing aircraft, despite the weight increase of a second pilot. At approximately one year into the project, a joint BAe/CoA decision was made to progress the project to completion with an `affordable’ set of modifications, providing the basic two seat capability, increased endurance, and approaching the desired

克兰菲尔德大学航空学院(CoA)认为,设计教学的最佳方式是让学生以结构化的方式在实践中学习设计。它还相信“细节决定成败”这句格言,一项设计只有在完成建造、试飞和认证后才算完整。设计师需要了解并经历从概念设计到认证的所有中间阶段。他们还需要被教导如何作为团队设计团队的成员,因为这是行业的通常运作方式。所有这些因素导致了航空航天飞行器设计全日制硕士课程的建立,其重点是集团设计项目(GDP)。多年来,这一理念被证明是成功的,并在飞机工程硕士课程的设计中得到了延续和扩展,这也是本文的主题。该课程是一个为期三年的非全日制硕士课程,其主要内容与全日制课程相同。学生们参加讲座模块,进行一项个人研究,并对GDP进行研究。正是这最后一个因素特别吸引了该课程的启动和主要客户,当时的英国航空航天公司(BAe)军用飞机部门。BAe喜欢教授设计过程的基本理念,即在项目组中安排一些人承担个人责任,但必须满足整个团队和项目的需求。1995年2月,飞机工程课程开始,有15名学生,他们开始了第一次入学,致力于对CoA的A1特技飞机进行重大修改,这本身就是以前学生工作的结果。航空航天飞行器设计全日制课程的国内生产总值集中在整个飞机的初步和详细设计,这已经在基本几何,质量,性能,特性等方面由工作人员预先定义。然而,BAe和克兰菲尔德公司希望在更大程度上解决完整的设计过程,如上所述。通过这种方式,学生们将在三年的时间里获得更广泛的航空航天项目的第一手经验,而不是在制造公司的主要飞机项目中工作。本文将详细介绍飞机工程教学计划,并描述第一次GDP,主要修改计划和克兰菲尔德A1特技飞机的飞行。学生们的任务是将现有的单座飞机改装成性能与现有飞机相似或更好的双座飞机,尽管第二名飞行员的体重增加了。在项目进行了大约一年的时候,BAe/CoA联合决定通过一套“经济实惠”的修改来推进项目的完成,提供基本的双座能力,增加续航力,并接近预期的性能。这架飞机由BAe和CoA人员进行了改装,并于1998年9月30日在克兰菲尔德自己的机场成功完成了正式的首次飞行,由自己的首席试飞员驾驶,从而完成了本文中描述的5个gdp中的第一个。还将提供有关最近入学学生的进展情况的资料。进气道2的主题是进一步修改A1,以进一步提高其横向机动性,通过一个新的复合垂直稳定器和方向舵。3号和4号入口利用克兰菲尔德在小型无人机设计和飞行测试方面的广泛专业知识,开发喷气动力无人机,作为具有钻石和混合翼身配置的不稳定飞机的飞行测试演示。这些将为克兰菲尔德大学在这些领域的广泛研究项目做出重大贡献。第五进气已经开始设计一种中高度、长航时(MALE)无人机,它将为克兰菲尔德和其他研究人员在遥感和微型卫星有效载荷领域提供一个平台。参考文献[4]给出了第一和第三gdp的更多细节。这些都是令人兴奋的,但具有挑战性的项目,继续发展最好的设计教学和相关的应用研究。图1显示了上述5个gdp是如何整合到克兰菲尔德战略飞机配置演示项目中的。它包括大量的博士研究、全职和兼职gdp以及政府资助项目的投入。

Aerodynamic optimisation of wings in multi-engined tractor propeller arrangements is discussed and analysed with a fast calculation based on a Trefftz-plane analysis where the conservation laws of mass, momentum and energy are fulfilled in a control volume surrounding the configuration. The paper discusses the formulation of the optimisation algorithm based on augmented Lagrange integrals. The effect of viscous effects is incorporated in the calculation process. The method was implemented in a computer program which enables the user to find the optimum lift distribution for minimum drag for any tractor propeller/wing arrangement of arbitrary shape. As input for the slipstream data the user can either select input of experimental data or generate artificial data using a simple slipstream model based on the well-known blade element theory with Prandtl tip loss factor. Some numerical studies show that optimisation of a modern medium speed turboprop aircraft leads to performance increase by adapting the wing shape.

采用基于Trefftz-plane分析的快速计算方法,讨论并分析了多引擎牵引车螺旋桨布置中机翼的气动优化问题。在Trefftz-plane分析中,质量、动量和能量守恒定律在控制体积内得到满足。本文讨论了基于增广拉格朗日积分的优化算法的公式。在计算过程中考虑了粘滞效应的影响。该方法在计算机程序中实现,使用户能够在任意形状的牵引机螺旋桨/机翼布置下找到最小阻力的最佳升力分布。作为滑流数据的输入,用户既可以选择实验数据输入,也可以使用基于著名的带普朗特叶尖损失因子的叶片单元理论的简单滑流模型生成人工数据。一些数值研究表明,现代中速涡桨飞机的优化是通过调整机翼形状来提高性能的。

Developing tools for reconstructing control signals for crash investigations 为事故调查开发重建控制信号的工具

In recent years, due to the globally increasing trend in air traffic volume, the aviation community has been touched by the occurrence of a number of crashes, although the overall aviation safety is actually improving in most countries. In the US the National Transportation and Safety Board (NTSB) begins its investigation by analyzing the wreckage along with the information from flight data recorder (FDR) and cockpit voice recorder (CVR). In most instances this set of information is enough for the NTSB to discover the cause of the crash; unfortunately, this is not always the case. Until a few years ago FAA regulations mandated the recording of 11–17 flight parameters without specifying the recording of the deflection of primary control surfaces. Following a few accidents where control surface failures were believed to be a likely cause of the crash, the FAA recently required the US-based airlines to retrofit the fleet with newer digital FDRs capable of recording a much larger number of parameters, including, of course, the deflection of primary control surfaces. This rule has a multi-year compliance period. However, some airlines are or have been seeking exemptions from this rule for some specific aircraft soon to be retired from service. Furthermore, only the US commercial fleet is affected by this ruling. Therefore, there is a need for a scheme that can reconstruct additional aircraft time histories to aid investigators for crashes with limited CVR information and where control surface failure is believed to be a factor. This paper describes a scheme formulated to reconstruct the aircraft primary surface deflection using data available from the current FDRs recording only 11–17 parameters. The scheme consists of two neural networks. The first is used to simulate the aircraft dynamics, while the second is used to reconstruct the primary surface deflections. The methodology is applied to simulated maneuvers from the non-linear model of an F-16 from a commercially available flight simulation software.

近年来,由于全球空中交通量的增长趋势,航空界已经被一些事故的发生所触动,尽管总体上航空安全在大多数国家实际上正在改善。在美国,国家运输和安全委员会(NTSB)通过分析残骸以及飞行数据记录仪(FDR)和驾驶舱语音记录仪(CVR)的信息开始调查。在大多数情况下,这组信息足以让NTSB发现坠机的原因;不幸的是,情况并非总是如此。直到几年前,美国联邦航空局规定要求记录11-17个飞行参数,而没有指定记录主控制面偏转。在发生了几起事故后,控制面故障被认为可能是坠机的原因,美国联邦航空局最近要求美国航空公司改装机队,使用更新的数字fdr,能够记录更多的参数,当然包括主控制面的偏转。该规则有一个多年的遵守期。然而,一些航空公司正在或一直在为一些即将退役的特定飞机寻求豁免。此外,只有美国商业船队受到这一裁决的影响。因此,需要一种方案,可以重建额外的飞机时间历史,以帮助调查人员在有限的CVR信息和控制面故障被认为是一个因素的情况下坠毁。本文描述了一种利用现有fdr记录的仅11-17个参数的数据来重建飞机初级表面偏转的方案。该方案由两个神经网络组成。前者用于模拟飞机动力学,而后者用于重建初级表面偏转。该方法应用于F-16的非线性模型的模拟机动,该模型来自商用飞行仿真软件。
