Project description DEENESFRITPL Novel cowls provide easy access to advanced engine systems in aircraft The aerospace sector is actively developing new systems and structures to make aircraft lighter, quieter, and more fuel-efficient. Ultra-high bypass ratio engines could play a critical role in helping future aircraft meet these goals. Integrating these engines onto the airframe poses challenges that can be addressed through shorter and slimmer nacelles (that house the engines). However, this requires new designs for the nacelle cowling system, the part that can be opened or removed for inspection and maintenance. The EU-funded NNEOS project is developing an innovative electromechanical actuator to open and close the cowls and keep them open during maintenance tasks. The design will enhance safety and accessibility while reducing weight and volume, thereby meeting required dimensions while further decreasing fuel consumption. Show the project objective Hide the project objective Objective NNEOS (Nacelle cowl NExt generation Opening System)NNEOS project is born to enable the use of new engines architectures like the UHBR (Ultra-High Bypass Ratio) that require shorter and slimmer nacelles and as a result a new approach to mainteinability and accessibility of the engine. Main objectives of the project:-Improve safety and accessibility to engine zones for maintenance/reparation through the development of an electromechanical actuator that integrates the functionalities of opening/closing the cowls as well as holding them at the open position during maintenance task-Optimize weight and dimensions with a design that favours the integration within the nacelle available space envelope: -At a system level, provide a potential reduction for the volume required for the equipment by 15% -At a system level, the aim is to achieve a 10% weight reduction associated to the system and connections when compared to the current systems being used. -Contribute to the reduction of the development time of the future engine architectures by 10%, through the optimisation of system integration for the power plant systems Provide a friendly design that is easy to use but ensures a safe operation of the nacelles-Bring the technology to TRL5.
