Abstract The overall objective of ACASIAS is to contribute to the reduction of energy consumption of future aircraft by improving aerodynamic performance and by enabling the integration of novel efficient propulsion systems such as contra-rotating open rotor (CROR) engines. The aerodynamic performance is improved by the conformal and structural integration of antennas. The installation of CROR engines is enabled by installation of an Active Structural Acoustic Control (ASAC) system in the fuselage. The integration such a system in fuselage panels will reduce sound pressure level in the cabin due to annoying multi-harmonic noise which is radiated by CROR engines. CROR engines are able to realize up to 25% fuel and CO2 savings compared to equivalent-technology turbofan engines (http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19890003194.pdf). The ACASIAS project focusses on challenges posed by the development of aero- structures with multifunctional capabilities. The following concepts structural concepts are considered: • A composite stiffened ortho-grid fuselage panel for integrating Ku-band SATCOM antenna tiles. • A fuselage panel with integrated sensors and wiring for reduction of CROR cabin noise. • A smart winglet with integrated blade antenna (integrated substrates into special foam, partly covered by a 1 mm glass/ quartz epoxy layer). • 4. A Fibre Metal Laminate GLARE panel with integrated VHF communication slot antenna. The 5,2MEuros valued 36-Months Action will bring together 11 partners from 6 countries covering the three main disciplines required: (composite) structures, advanced antennas and miniaturized sensors in a multi-disciplinary project. The innovations and integration of these disciplines will lead, besides operational cost reduction and decreased emissions for airlines, also to a more competitive supply chain in the aviation sector, which increasingly uses composite structures.
