Eurocopter,
Thanks to the research already carried out over the last few decades – for example, the development of three successive generations of the Fenestron tail rotor – Eurocopter now has the quietest range of ) helicopters in the world. These efforts are now being pursued and intensified, in order to comply with ever stricter and widerranging environmental requirements.
For several years, Eurocopter has been carrying out research as part of the Optimal and Friendcopter programmes in cooperation with some 30 partners.
The primary concern of this research is to reduce noise pollution:
– By reducing aerodynamic noise through the development of active noise control systems for main rotors
– By reducing engine noise through studies on engine integration, the shape, position and design of tail pipes and air intake.
Significant efforts are also being devoted to developing quieter flight procedures. A major flight test campaign was performed with an EC130 in 2007 to test a wide array of situations – including takeoffs, approaches and cruising. This work earned the team international recognition in the form of the Cheeseman prize for ‘best helicopter-related technical publication’, which was presented at last year’s European Rotorcraft Forum in Kazan, Russia and at the American Helicopter Society Forum in Montreal, Canada.
Similar tests are currently being conducted using an EC135 and are being accompanied by the development of a software tool called HELENA (HELicopter Environmental Noise Analysis) that predicts noise footprints and will help to define procedures that can be adapted to every helicopter type.
Eurocopter is playing a major role in the European Clean Sky programme, which was officially launched on 5 February 2008, and which is of interest to the entire aeronautical industry. Clean Sky has defined six research platforms or ITDs (Integrated Technology Demonstrators), including the Green Rotorcraft platform, which is specifically devoted to helicopters and tilt-rotor aircraft. Certain research activities also cross over: the Systems for Green Operations ITD covers electrical power systems; the Eco-Design ITD concerns the complete industrial cycle; and part of the Sustainable and Green Engines ITD focuses on the design of turbine engines for helicopters.
All of this research work aims to reduce greenhouse gas emissions (through reductions in fuel consumption), to reduce noise and to create a green product life cycle – from manufacturing until the aircraft is recycled at the end of its service life. To ensure this green life cycle, Eurocopter’s aim is to comply as fully and as quickly as possible with REACH, a European Community regulation, which aims to restrict the use of harmful chemical or toxic substances throughout the helicopter maintenance and production processes.
Following in the footsteps of the Optimal and Friendcopter programmes and, in addition to the work on aircraft design, further research will focus on the operational use of helicopters. This research will develop means for crews to optimise trajectories and favour quieter and more energy-efficient flight conditions.
The world’s leading helicopter manufacturer is determined to develop the greenest possible range of aircraft – as this broad range of research activities clearly shows.
Established in 1992, the Franco-German-Spanish Eurocopter Group is a Division of EADS, a world leader in aerospace, defence and related services. The Eurocopter Group employs approx. 14,000 people. In 2006, Eurocopter confirmed its position as the world’s No. 1 helicopter manufacturer with a turnover of 3.8 billion euros, orders for 615 new helicopters, and a 52% percent market share in the civil and parapublic sectors. Eurocopter offers the largest civil and military helicopter range in the world.
