Günümüzde insanlığın ortak birikimi olarak değerlendirilen havacılık, 1903 yılında Wright kardeşlerin havadan ağır ilk motorlu uçağı icat etmesiyle farklı bir boyut kazanmıştır. Havacılığın askeri alanda kullanılmaya başlanması, ardından sivil havacılığın gelişimi ile ülkelerin kendi havacılık faaliyetlerinin hız kazanması günümüz havacılığının şekillenmesinde etkili olmuştur. Geçmişten günümüz...

Composite materials offer an appealing combination of low weight and high strength that is especially sought after in high-performance applications. The use of composite materials has and is continuing to increase, and the use of the material has been shown to provide substantial weight savings in for example aircraft design. With an increased use of composite materials follows an increased dem...

Radomes protecting sensitive radar, navigational, and communications equipment of, e.g., aircraft, are strongly exposed to the environment and have to withstand harsh weather conditions and potential impacts. Besides their significance to the structural integrity of the radomes, it is often crucial to optimize the composite structures for best possible radio performance. Hence, there exists a s...

Service agreements are one-of-a-kind, and commit the service providers to certain configuration, execution, and delivery of their processes and resources over a long time. To improve productivity, the providers need a way to mass-customize the service they produce while the customers need to be able to evaluate and bench-mark the service they obtain. The field lacks sufficient results to allow ...

Manufacturing technology selection is traditionally a human-driven approach where the trade-off of alternative manufacturing investments is steered by a group of experts. The problem is a semi-structured and subjective-based decision practice influenced by the experience and intuitive feeling of the decisionmakers involved. This paper presents a distinct experience-based decision support system...

Since the part design process is mainly based on constrains like geometry and function, a static optimization approach can be used. Corresponding optimizing algorithms would yield appropriate values for the part and its function. A more complex situation takes place in the manufacturing and assembly processes: their complex functions are time dependant and may run in a variety of logical arrays...

ice can form on aircraft surface at 0° c or colder temperatures when liquid water is present. this can happen both on the ground and at the flight levels of the aircraft. aircraft icing has not only an impact on flight safety but has also an economic impact. according to the report of research department of the faa (federal aviation administration), from 1982 to 2001, 13% of accidents due to ai...
