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<span> 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","PeriodicalId":100070,"journal":{"name":"Aircraft Design","volume":"3 4","pages":"Pages 217-238"},"PeriodicalIF":0.0,"publicationDate":"2000-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1369-8869(00)00006-9","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73950363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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<span> (FDR) and cockpit voice recorder<span> (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 </span></span></span>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.</p></div>","PeriodicalId":100070,"journal":{"name":"Aircraft Design","volume":"3 3","pages":"Pages 175-203"},"PeriodicalIF":0.0,"publicationDate":"2000-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1369-8869(00)00017-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91694020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
