Aircraft development

Clearly, aerospace has been a major driver for advanced structural materials. It will continue to be a driver, although perhaps at a slower pace, particularly for weight reduction and higher temperature reliability. The slowdown of military aircraft development presents a unique problem because many of these programs, such as the advanced tactical fighter (ATF), were test beds for advanced-performance materials for which... 

The pace of aircraft development was such that even Fighter Command was confronted with a serious problem of obsolescence in 1950. The RAF s jet fighters in service at that date, the Gloster Meteor and the de Havilland Vampire, had straight wings, which were aerodynamically less efficient than swept-back ones. The earliest versions of the Meteor and Vampire had entered service in 1944 and 1946 respectively, but plans for their replacement were related to an assumption that a major war would be unlikely to occur until about 1957. Resources for research and development had been drastically reduced at the end of the war and it was decided to take a risk in concentrating on really big advances in... 

Although it is possible to improve catalytic converters in gasoline-powered vehicles and to develop exhaust control devices for diesel-fueled vehicles and even aircraft, development in these areas is slow. Extensive research efforts in these areas are desperately needed and should be strongly encouraged. However, in reality, implementation of these devices will be far in the future and the problems of today are increasing. 

ABSTRACT Safety is of prime importance for aircraft and must be considered from the beginning of the design process. Conducting a safety analysis involves considerable effort, particularly if traditional methods, such as manual fault tree analysis, are used. This may explain why analyses are performed usually only once or twice during an entire aircraft development. Furthermore, traditional methods are hardly linked to other tools for system conceptual design. 

For example, in aircraft development is involved the tests performed on the integrated ground and flight system, including all elements of the payload, its control, stimulation, communications, and data processing to demonstrate that the entire system is operating in a manner to fulfill all mission requirements and objectives.
