Too little scope for development in today's aircraft technology
June 27, 2007New technology can do much to improve certain aspects of aviation in terms of sustainable development over the next fifty years, but this will be nowhere near enough to compensate for the expected growth in air travel. This is the view of researcher Alexander de Haan, who will receive a Ph.D. at Delft University of Technology in the Netherlands on Wednesday, June 27 for his research on this subject.
Ph.D. candidate Alexander de Haan has researched how new aircraft technology can contribute to sustainability in aviation. He has developed a model comprising a number of different scenarios that can be used to assess this sustainability in the coming fifty years.
De Haan concludes that, through technological development, progress can certainly be made with regard to aspects such as noise pollution and CO2 emissions. There are potential benefits to be gained, for example, from increased scale, new landing and take-off procedures/routes, the use of lightweight materials such as Glare (a composite material developed at Delft University of Technology), and new aircraft design concepts such as the Blended Wing Body.
According to De Haan, the benefits of applying this new aircraft technology will amount to no more than tens of percents for a number of sustainability aspects. From the perspective of sustainability, therefore, technological advances will certainly not be able to keep pace with the rapidly increasing demand for air travel over the next fifty years. This is even the case in the scenario with the lowest growth rate. De Haan predicts that the demand for air travel will at least double during that period.
In De Haan's view, fifty years after the advent of the jet engine, today's aircraft design models offer little scope for further development. He believes that, in order to make real progress/advances with regard to sustainability, a radically different aircraft concept is needed that incorporates not only the expertise of the various technical disciplines, but certainly also the behavioural disciplines and political aspects.

Who's your winner for UK's top engineering prize of £50,000?
The Royal Academy of Engineering has chosen four companies as finalists for this year's MacRobert Award for innovation in engineering. For the first time, the public will have the opportunity to 'choose' their favourite of the four finalists. The short listed entries cover a wide range of areas, from fighter aircraft technology to a novel process in medical diagnostics. The innovations from the four companies are as diverse as at any time in the award's 33-year history. On 7 May, the Science Museum will be launching an interactive web page on the finalists with a competition open to under -18 year olds to choose their MacRobert winner. The competition is based on a question about why they

Hydrogen Aircraft Technology by G. Daniel Brewer (Author) Liquid hydrogen is shown to be the ideal fuel for civil transport aircraft, as well as for many types of military aircraft. Hydrogen Aircraft Technology discusses the potential of hydrogen for subsonic, supersonic, and hypersonic applications. Designs with sample configurations of aircraft for all three speed categories are presented, in addition to performance comparisons to equivalent designs for aircraft using conventional kerosine-type fuel and configurations for aircraft using liquid methane fuel. Other topics discussed include conceptual designs of the principal elements of fuel containment systems required for cryogenic fuels, operational elements (e.g., pumps, valves, pressure regulators, heat exchangers, lines and fittings), modifications for turbine engines to maximize the... |
