Benefit Analysis Value and Risk Assessment of New SARISTU-Technologies

The value and risk assessment investigates whether the SARISTU aim of improving aircraft efficiency has been met by achieving a reduction in the total weight and operating costs. Process times for manufacturing steps, together with pertinent weight data and weight impact calculations, are used to enable this assessment. The focus lies on processes established in the manufacturing of coupons, elements and details of the SARISTU-test pyramid in AS04 and AS06-10, as integrated into the sub-component technology demonstrators in IS13. A tool has been developed that allows results to be upscaled to component level and allows a comparison of SARISTU-technologies against state-of-the-art manufacturing methods for carbon fibre reinforced fuselages. Serial production and operational impacts have been considered. Additional technologies have been included, such as structural health monitoring (SHM), which was utilized for improving damage detection capabilities.
