SUMMARY

1. The Rotorcraft in SRA 2

Scenario / HLTCs

2. Rotorcraft in FP7

Clean Sky JTI – Green Rotorcraft Platform




ROTORCRAFT IN SRA 2

ACARE (Advisory Council for Aeronautical Research inEurope) SRA2 (Strategic Research Agenda) has stated

an increasing role of rotorcraft as a competitive and

affordable mode of transportation for point to point

connection, compared with road transport and with

reduced impact on infrastructures. Application both onnew and scheduled services.

The future ATS (Air Traffic System) model includes

rotorcraft contribution based on both current and futuretechnology.




ROTORCRAFT IN FP7

The Clean Sky JTI Green Rotorcraft Platform is

established with AgustaWestland and Eurocopter as co-

leaders.
