This paper describes the selection of the ideal variable inlet concept group by utilising results of aerodynamic investigations, system safety analyses and integration studies. Aerodynamic and functional inlet requirements are explained, and variable inlet concept groups are introduced. The concept evaluation by means of a weighted point rating is presented. The respective concept groups are analysed and evaluated regarding economic, functional and safety requirements. By means of this evaluation, the concept group that adjusts the inlet geometry by rigid segment repositioning is identified as most suitable concept group. The early selection of the most suitable concept group enables more detailed subsequent concept investigations, potentially enabling the technology of variable inlets for future commercial aircraft.

The article describes the modernization of consumer characteristics, through the selection of the quality indicators nomenclature using cluster analysis, and bringing the complex technical system (CTS) model using the example of civil aviation technology (CAE) to an invariant form. Also, the article uses a methodological apparatus for assessing the degree of product innovation taking into account the total number of product technical characteristics presented by regulatory and design documentation for the products being created. The obtained characteristics were synthesized by translating consumer requirements of the main participants of the civil aviation equipment market segment. Taking into account the opinions of various consumer groups, five clusters were created and the basic structures of the model of a complex technical system were modeled. Applied technological device suitable for solving problems related to structured and classification of valuable technical characteristics with a planning horizon of 10 years various representatives of the company producing different brands of products related to complex technical systems of civil aviation equipment.

Studies of post-1945 Britain have often concentrated upon political and foreign policy history and are only just now beginning to address the question of the restructuring of the British economy and domestic policy. Civil aviation, a subject of considerable interest to historians of interwar Britain, has not been given a similar degree of attention in the post-1945 era. Civil aviation policy was, however, given a very high priority by both the 1945-51 Labour government and its Conservative successors. Civil aviation represented part of the effort to return Britain to a peacetime economy by transferring resources from the military into the civil aircraft industry, while at the same time holding for Britain a position of pre-eminence in the postwar expansion of civil flying. As such, aviation was a matter of great interest to reconstruction planners during World War Two, and was an important part of the Attlee government's plans for nationalization.Civil aviation was expected to grow rapidly into a major global economic force, which accounted for the great attention paid it in the 1940s and 1950s. Its importance to Britain in the postwar era lay in the value of air connections to North America, Europe, and the Empire and Commonwealth, and also in the economic importance of Britain's aircraft industry. In a period when the United States was by far the largest producer of commercial aircraft, the task of Labour and Conservative governments was to maintain a viable British position against strong American competition. What is particularly interesting is the wide degree of consensus that existed in both parties on the role the state should play in the maintenance and enhancement of this position.

Economic Considerations

The performance of complex systems, such as power plants and commercial aircraft, is based on the integration of human, software, and hardware elements. They are designed to operate safely under normal and disturbance conditions. Ideally one would validate that safety and productivity goals can be achieved prior to actual operation. While some types of systems can be tested in actual operational environments, validation is especially difficult when safety or economic considerations preclude testing the types of disturbance conditions that the integrated system is designed to handle. Thus the conceptual and methodological challenges to validating such systems are significant and new approaches are emerging. The papers in this symposium will describe approaches taken to validation using examples from commercial nuclear power, civil aviation, military, and medical systems.

Abstract Arguably, one of the most important requirement a building have to meet in case of fire is to ensure the safe evacuation of its users and the work of rescue teams. Consequently, issues related to the risks associated with falling parts of facades are fairly well known around Europe. Even though not equally well defined as other fire safety requirements concerning glazed facades, there is plenty of test methods for assessment of facades regarding falling parts, mostly based on an approach related to fire spread. In this paper selection of test method for assessment of facades regarding falling parts is briefly presented. However, focus of this work is on fire test of typical glazed segment of façade performed in ITB Laboratory. Results of the test positively verifies conjecture that solutions with glass units configured with thin, tempered glass panes on the outer side should pose no threat. However, the question has been raised whether the behaviour of other glass unit solutions (with additional coatings or laminated) would be similar.

Favorable Conditions

The modern airport is a complex environment in terms of size, traffic, safety requirements and operational reasons, where the primary goal is to create favorable conditions for handling passengers and goods transported by aircraft. All elements of aerodrome infrastructure are an essential medium for carrying out transport and service processes. To be in the infrastructure of the airport should meet the current requirements and standards of carriers who treat this issue as a key criterion for the choice of the airport in terms of where they provide air operations. Modern solutions are increasingly attracting the attention of their customers. The main reason is to place services while increasing security. Europe is the target of terrorist organizations, so the critical infrastructure manager, in accordance with Annex 17 to the Chicago Convention on the State's obligations in the field of civil aviation, outweighs the adoption of an appropriate strategy that outweighs the various technical security solutions. The aim of the article is to present the currently operating technical systems at European airports. In order to achieve the intended goal, the materials available in the scientific publications and data provided by the selected airports were analyzed.
