LiTRAS will develop a robust concept for an innovative Thrust Reverser Actuator System (TRAS) based on linear motor technologies that will allow further and deeper integration capability inside the pylon and nacelle structure and will greatly improve Thrust Reverser performances against the challenging Nacelle environment. The LiTRAS concept will be compact, safe, reliable and easy to operate and will be able to withstand the harsh environmental conditions required. In addition, LiTRAS concept will provide locking functionality (PLS, Primary Locking System) preventing from any inadvertent Thrust reverser deployment in Flight and a Mechanical Deployment Unit (MDU) for manual opening of the cowls for maintenance operations. The system will also incorporate a TRCU (Thrust Reverser Control Unit) concentrating the power supply, control and monitoring electronic hardware of the linear actuator. The main objectives of the LiTRAS project are: • Investigate linear motor technologies applied to a thrust reverser module of a short middle range UHBR engines with further and deeper integration capability inside the pylon and nacelle structure. • Improve cost, weight, efficiency and maintainability of the Thrust Reverser Actuation System by developing a compact, reliable actuator based on a linear motor without mechanical transmission and directly integrated with the nacelle structure. • Investigate on the possible solutions that could be given to extreme environmental conditions if required. • Bring the technology to TRL4 • 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 TRAS. • Deliver an Aircraft qualification assessment and define the necessary steps to bring the technology from TRL4 to an aeronautical and certifiable equipment.

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.

The main objectives of NIPSE are to provide technologies to - reduce Integrated PowerPlant System development time of future aeroengines by 10% - enable the 2 to 3% environmental related gains in fuel burn and reduction in emissions looked at by these new aeroengine architectures (especially Ultra High Bypass Ratio and Open Rotor) through improved aeroengine equipment solutions. The objectives will be achieved through several elements. NIPSE will develop key equipment and capabilities, in particular: - multivariable optimisation methodologies, - more efficient heat exchangers, - smaller equipment, and - novel electrical and pneumatic interconnections to enable a means of developing better competitive solutions for future aeroengine architectures in a shorter development time. This will be performed taking into account line maintenance issues to ensure the improvements of aeroengine architecture and associated equipment do not adversely impact the passenger experience. This is relevant to the work programme in increasing competitiveness of European companies through development of technologies to achieve fast, best solution approaches for installation of aeroengine equipment, allowing securement and enhancement of existing European workload for this equipment, and enhancing exports for Europe. Development of key technology in equipment definition, installation and optimisation enables existing and future aeroengine technologies to better achieve their goals, thus enhancing European competitiveness within aeroengine market. Without NIPSE, the true potential of the new aeroengine architectures will not be achieved and societal gains will not be met.
