Aboard the aircraft were Eurocopter test pilot Hervé Jammayrac and flight test engineer Daniel Semioli “We were impressed by the ease at which this speed objective was attained,” Jammayrac explained. “The X3 handles extremely well, demonstrating remarkable stability at high speed – even with the autopilot off. We are very proud of this achievement, which results from the dedicated efforts of all those who have worked on the project.”

Eurocopter began X3 flight testing last September in a program that combines the excellent vertical takeoff and landing capabilities of a helicopter with aircraft-type fast cruise speeds of more than 220 kts. After the X3 achieved the initial true airspeed goal of 180 kts. (333 km./hr.) in November at a reduced level of engine power, the X3 underwent its planned gearbox upgrade and safety inspection.

Since returning to flight last week, the X3 quickly demonstrated its performance at full engine power, including impressive climb and descent rates, as well as excellent maneuverability, while also confirming the hybrid propulsion system’s outstanding capabilities for acceleration and deceleration.

In the test program to date, the X3’s basic handling characteristics and stability have been validated throughout the aircraft’s flight envelope without the need of a stability augmentation system, which has been confirmed in testing performed with the autopilot disengaged and engaged. In addition, the hybrid aircraft has low vibration levels without the use of passive or active anti-vibration systems, providing flight characteristics comparable to those of the best traditional design helicopters currently in service.

The X3 utilizes a Eurocopter Dauphin helicopter airframe equipped with two turboshaft engines that power a five-blade main rotor system and two propellers which are installed on short-span fixed wings. This hybrid configuration creates an advanced transportation system offering the speed of a turboprop-powered aircraft and the full hover flight capabilities of a helicopter.

The company envisions a wide range of utilizations for this concept, including long-distance search and rescue (SAR) missions, coast guard duties, border patrol missions, passenger transport, offshore operations and inter-city shuttle services. It also could be well-tailored for military missions in special forces operations, troop transport, combat SAR and medical evacuation – benefitting from the hybrid aircraft’s combination of higher cruise speeds with excellent vertical takeoff/landing performance.

Flight testing of the X3 is being performed from the DGA Flight Test Center in Istres, France. The flight test program will continue throughout 2011 to explore the hybrid helicopter’s full flight envelope and evaluate all of the possibilities offered by this new technology.

I think Sikorsky's helicopter is faster. And the Russians are making one too.

True. Sikorsky have been fastest (287mph) but this design may allow it too exceed that record. It has reached speeds of 267 mph so far. It would be good for fighting those damn forest fires.

This design is very impractical and it will never go into production in the form that it is today.

Only Putin can stop the forest fires. After he wrestles a bear.

...and then tames it to carry the hose to the next wild fire. Let's hope the bear knows something about filling bogs too.

You have to be really stupid to fly a helicopter. It is much more dangerous than riding a yellow marshrutka in Moscow. And you ride a marshrutka only if you have a death wish.
