Quoted extracts from another location on the web.

European planemaker Airbus said today that its C295 technology demonstrator had successfully performed its maiden flight from the final assembly line in Seville, Spain. The aircraft, Airbus C295 Flight Test Bed 2 (FTB2), will now commence a series of flights testing its new semi-morphing wing. Furthermore, it will evaluate a new flight-control system and a SatCom antenna embedded within the aircraftís fuselage.

The main modifications to the C295 in-flight demonstrator include a new high-efficiency semi-morphing wing. In addition, the planemaker says, an innovative flight control system for primary control surfaces is capable of adjusting these in-flight. This leverages digital control systems to optimize the aerodynamic shape of the wing in flight.

Airbus has also redesigned a new, multifunctional flap to include flap tabs in the trailing edge controlled by electromechanical actuators. The testbed aircraft also has new, dynamic winglets.

Based on the Airbus C295, the Flight Test Bed 2 is an in-flight demonstrator of the European Clean Sky 2 (CS2) and the EU Horizon 2020 research and innovation programme, where technologies related to CS2’s future regional multimission aircraft are tested.

The modifications include new materials and technologies designed to achieve noise, CO2 and NOx emissions reduction. With these technologies applied in a future regional multimission configuration, up to 43% CO2 and 70% NOx reductions can be achieved in a typical Search and Rescue mission of 400 nautical miles, as well as 45% less noise during take-off.

The main modifications in the aircraft are a new high-efficiency semi-morphing wing, new dynamic winglets and a flat panel SATCOM antenna integrated within the top of the fuselage. In addition, innovative flight controls for primary control surfaces, including ailerons, flaps and flap tabs with improved aerodynamics, are capable of adjusting in-flight and contribute to a more efficient high lift system.

The new flight control system leverages digital control systems to optimise the aerodynamic shape of the wing in flight, while a new multifunctional flap has been completely redesigned and includes flap tabs in the trailing edge controlled by electro-mechanical actuators.

But the advantages also extend into the manufacturing process, not least with the use of advanced materials and manufacturing ranging from the use of Scalmalloy and additive manufacturing, to a new assembly method for the aero structures of the wing. A one shot assembly approach has been used for the new composite winglet and winglet tab, moving from the conventional ribs approach to a multi-spar integrated torsion box. Finally, jig-less methods have been used for the assembly of flaps and ailerons.

As a result, the C295 FTB2 brings improvements not only to the purely operational aspects of the aircraft, but helps introduce new improvement to the design and manufacturing process.
