AERONAUTICS SCIENCE & TECHNOLOGY
SOME RECENT CLEAN SKY 1 ACHIEVEMENTS ONE PIECE BARREL (OPB)
This component represents the ‘pioneer’ of composite technology application to such an important primary structure (fuselage) of a regional aircraft.
Alenia Aermacchi composite fuselage OPB demonstrator pre-production manufacturing came to light in December 2013. The One Piece Barrel (2.9 m length – 3.5 m diameter) has been realized with a co-bonding process where pre-cured Omega stringers are bonded on green skin. The OPB demonstrator of 90-seat advanced turboprop aircraft is based on: (i) more innovative multi-functional layer and multi-layer architectures leading to considerable weight reduction; (ii) better acoustic insulation; (iii) increased all-impact performance; (iv) use of various sensor technologies to monitor the health status of the structure and report the degradation of its mechanical properties.
HYBRID ICE PROTECTION SYSTEM
Within the framework of SGO ITD (System for Green Operations Integrated Technology Demonstrator) Clean
AMONG CUTTING-EDGE TECHNOLOGIES LEADING TO REACH ACARE OBJECTIVES
Sky programme, Aerotek UK, working with AleniaAermacchi, was responsible for the planning execution and reporting of an icing test conducted on ice protected wing section provided by Dassault Aviation. The equipment HIPS (Hybrid Ice Protection System) was provided by Zodiac Aerospace. The tests were completed successfully in the IWT (Icing Wind Tunnel) of the Italian Aerospace Research Centre: the test conditions were taken from the in-flight icing design atmosphere specified in CS-25 Appendix C.
Low Drag Laminar Wing
Contra-Rotating Open Rotor technology (CROR)
Low drag laminar wing for future short and medium range, large passenger aircraft. High compression Engine (HCE)
Contra-rotating open technology (CROR) engine is intended to power the single-aisle jets.
Eurocopter High Compression Engine (HCE) model is a new technology, providing sustainable alternative to the classic turbine engine, reducing both fuel consumption and emissions. From information provided by Clean Sky
