EADS will showcase a diesel-electric hybrid helicopter concept and aviation biofuel made from algae at the 2010 ILA Berlin Airshow next week at Berlin-Schönefeld Airport.

Hybrid helicopter concept. A full-scale model of a conceptual helicopter with a diesel-electric hybrid propulsion system displays EADS Innovation Works’ research towards more efficient propulsion system solutions for future small helicopters. Fuel consumption and emissions can be considerably reduced by the hybrid propulsion technology.

EADS Innovation Works exhibits will be complemented by selected displays of Eurocopter’s environmentally friendly “bluecopter” technologies. These include the Blue Edge main rotor blade, which provides a passive reduction in noise levels, using a double-swept shape different from present-day blades. The piezo-active rotor control system called Blue Pulse has the primary objective of reducing noise levels generated by the interference of the rotor blade tip vortices from one rotor blade with the following blades.
