Flying qualities and flight control system design for a fly-by-wire transport aircraft

Gautrey, Jim 09 1900 (has links)
Fly-by-wire flight control systems are becoming more common in both civil and military aircraft. These systems give many benefits, but also present a new set of problems due to their increased complexity compared to conventional systems and the larger choice of options that they provide. The work presented here considers the application of fly-by-wire to a generic regional transport aircraft. The flying qualities criteria used for typical flying qualities evaluations are described briefly followed by analysis of several past transport aircraft flying qualities programmes against these criteria. From these results, some control law independent design requirements are formulated for a civil aircraft for the approach and landing task. These control law independent flying qualities criteria are intended to be used with any generic rate-like control law for a transport aircraft and enabled a number of different control laws to be designed. The results of a number of flying qualities evaluations are presented. Both an ILS approach task and a formation flying task were used. The effects of windshear were also considered. It was found that control laws which maintain flight path are suitable for the ILS approach task, while most rate-like response characteristics give good flying qualities for the formation flying task. Finally, the conclusions drawn from these evaluations are presented, and both the Civil and Military current airworthiness requirements are assessed. In addition to the flying qualities work, a study is made of the management issues associated with fly-by-wire design. A fly-by-wire aircraft design programme was proposed and the project management issues associated with this were considered. A timescale was proposed for the design process for a generic regional aircraft, and the critical path for this process is presented. / EPSRC; Avro International Aerospace.

The Canadian No Fly List: A Sociological Analysis of its Supposed Distinctiveness

Rozdeba, ANDREA 15 January 2009 (has links)
Since the events of 9-11, aviation security has become a mounting concern for both the American and Canadian government. Because of the alleged “threats to security,” the Canadian government has followed in American footsteps and enacted the Passenger Protect Program, otherwise known as the “no fly list.” This thesis will examine the emergence of the Canadian version of the no fly list in the context of the U.S. “Secure Flight” program in order to analyze the claim that the Canadian list is unique and distinct from the American version. Drawing from the literature on surveillance and risk, this thesis suggests that both lists are operating on the precautionary principle and are thus not distinct in purpose, process or overall outcome, and that a “made in Canada” approach is a misleading notion. In fact, this thesis will show that the Canadian and U.S. governments continue to share no fly lists, use the same criteria and sources for placing an individual’s name on the list, and handle redress issues in the same manner. Most importantly, the consequences for ordinary citizens are the same regardless of whether one finds themselves on the Canadian or the American list. This thesis will (a) describe the origins of the no fly list in Canada and the USA, (b) examine the ways in which personal data are obtained from the Passenger Name Record (PNR), how these are used to construct the list(s) and how they are mined for further purposes and (c) what the consequences are for specific classes of persons, especially minorities, refugee and asylum claimants, civil libertarians, peace activists and others. / Thesis (Master, Sociology) -- Queen's University, 2009-01-14 18:08:51.773
