The main objective for the Clean Sky 2 Large Passenger Aircraft Programme (LPA) is to further mature and validate key technologies such as advanced wings and empennages design, making use of hybrid laminar airflow wing developments, the integration of most advanced engines into the large passenger aircraft aircraft design as well as an all-new next generation fuselage cabin and cockpit-navigation. Dedicated demonstrators are dealing with research on the best opportunities to combine radical propulsion concepts, and the opportunities to use scalled flight testing for the maturation and validation of these concepts via scalled flight testing. Components of hybrid electric propulsion concepts are developed and tested in a major ground based test rig. The LPA program is also contributing with a major work package to the E-Fan X program.
The R&T activities in the LPA program is split in 21 so-called demonstrators. In the project period 2020 and 2021 a substantial number of hardware items ground and flight test items will be manufactured, assembled tested. For some large items like the Multifunctional Fuselage demonstrators or the HLFC wing ground demonstrator the detailed design and manufacturing of test items will be commenced.
For the great majority of contributing technologies a Technology Readiness level (TRL) 3 or 4 will be accomplished or even exceeded.
Based on data generated for each key technology contributing to the LPA program inputs will be provided to the CleanSky Technology Evaluator via the integration in agreed concept aircraft models in order to conduct the overall CS2 assessment. LPA is also contributing to conduct Eco Design Life Cycle assessments for selected LPA technologies.
