All R&T activities conducted in the LPA IADP in 2018 do focus on the development and maturation of key technologies for next generation of large passenger aircraft contributing to the key CS2 objectives with respect to reduction of the CO2 and NOx emission, noise emission, improving industrial competitiveness in aviation and mobility in three main research areas called “Platforms”

• Platform 1 “Advanced Engine and Aircraft Configurations”: Definition and down selection of key technologies to integrate Ultra-efficient Ultra-High Bypass Ratio turbofan engine, freeze for a large scale flight demonstration. Development of aircraft architecture for radical propulsion concepts including hybrid electric. Development of manufacturing concepts for a simplified HLFC horizontal tail plan, development for an HLFC wing demonstrator. Preparation of a scaled flight test demonstrator to validate future radical aircraft configurations.
• Platform 2 “Innovative Physical Integration Cabin – System – Structure” : Completion of a next generation Multi-Functional Fuselage concept aiming to combine fully integrated systems, an advanced structure enabling a radically changes manufacturing and assembly concept with key features enabling the application of factory 4.0 technologies. Based on concepts frozen in 2016, development of a Movable Passenger Service Unit (MPSU), Environmentally Friendly Fire Protection (EFFP) and Fuel Cell Powered Galley (FCPG). Design of major elements and components for the Next generation lower center fuselage.
• Platform 3: “Next Generation Aircraft Systems, Cockpit and Avionics” The definition of key functions and enablers for a disruptive cockpit for future large passenger aircraft was virtually completed in 2018. Part of the key technologies were developed to a status of component tests and were partially prepared for the insertion to an advanced regional aircraft cockpit and a biz jet cockpit, both aiming for a substantial reduction of workload, testing on ground and in flight started for some components respectively technologies in 2018. A final level of specifications was accomplished for virtually all advanced systems maintenance activities.

All LPA major technologies have been considered to be part of PANEM models prepared for the CleanSky Technology Evaluation. An update of reference models were delivered in 2018, updated “concept aircraft models” will be provided in Q1/2019.

LPA activities of high relevance for Ecodesign are identified to contribute to the CS2 Life Cycle Assessment and a CS2 EcoDesign Life Cycle Inventory.

Final results

All LPA technologies are aiming to contribute to a significant improvement of fuel burn efficiency, reduction of CO2 and NOx gaseous emissions and reduction of community and cabin noise for large aircraft. The developed technologies of to integrate most advanced power plants and aerodynamically much more efficient wing technology by means of the application of laminar technologies to short-medium and long range aircraft operating at high subsonic speed is well bejond state of the art.
Structural concepts under development to design, manufacture and assemble next generation fuselages in advanced thermoplastic CFRP offer new opportunities in apllying automated production and factory 4.0 concepts, which is well beyond state of the art of current design concepts and production methods.
The disruptive cockpit under development for next generation large passenger aircraft is the key technology to enable a single pilot operation, advanced cockpit systems and functions will substantially reduce the pilot workload operating future business jets and regional jets.
