Structural testing of major aircraft components is a very expensive and time-consuming process that significantly adds to the overall cost of designing and certifying a new aircraft product. If testing can be reduced, based on validated and safe numerical analysis methods, this will provide the European aircraft industry with a significant business and technological advantage. Structural certification, based on a virtual testing process, appears a promising way to achieve the following global objectives in a medium term of five to seven years. MUSCA's main objectives are to develop, test and validate new technologies for extending and improving large-component structural static analysis up to failure within the non linear (NL) domain. Propositions will be made to the Airworthiness Authorities for recommendations for a more cost effective structural justification process that makes greater use of advanced numerical simulation methods that still meet Airworthiness Authority and safety requirements. MUSCA will contribute to reducing the need for large component tests by extending the use of reliable, large-scale, NL calculation and reliability methods. MUSCA will enable improved preparation and exploitation of the remaining necessary physical testing through further validation of analysis methods, and the use of parametric and design sensitivity studies. Strong encouragement will be provided for further integrating numerical analysis methods into the design and certification process, and in the reduction of structural tests required for the certification of aircraft structures. |
