ALCAS – ADVANCED LOW COST AIRCRAFT STRUCTURES GENERAL OVERVIEW (Длительность 02.2005-04.2011)
The ALCAS project is partly funded under the 6th framework of the European Commission. Thus the partners are coming from all over Europe. The expected outcomes of the ALCAS project are validated wing and fuselage structural concepts and design architectures, which contribute to a reduction in operating costs. The project is integrating and validating developed mature and new composite technologies through the design and manufacture of appropriate wing and fuselage assemblies that represent both airliner and business jet products.
The ALCAS consortium consists of 60 partners out of 18 European countries including associated and candidate countries. Through this membership the consortium is covering the full development and production chain and is providing a major contribution to the European Research Area, thus developing the European Aerospace research and development community, and encouraging strong links and relationships between industry, research institutes, universities and mall and medium enterprises (SMEs).
The project objective is approached through:
Realising the weight saving potential of composite materials by extending the application of composites to more complex and more highly loaded structure, improving the performance of composite structures, increasing the ‘design to composites’ approach, assessing system architecture requirements, and developing design, that meets architecture requirements while minimizing the weight of the installation,
Reducing the manufacturing costs of composite components by developing the use of dry fibre and resin infusion / injection technology, improving automated prepreg technologies to cover complex contours, considering out-of-autoclave processes, as this decreases the number of parts through a higher level of structural integration and investigating low cost and ‘ready to paint’ tooling concepts, along with reducing the costs of assembly techniques, and further application of automation,
Reducing maintenance costs, as the application of carbon fibre composites is expected to reduce the in-service inspection requirements. The project is also seeking to validate allowable damages and simplified repair solutions developed in the industry.
