Eurocopter poursuit sa tournée américaine avec son hélicoptère hybride à grande vitesse X3 aujourd'hui à Manassas, en Virginie, où l'avion a effectué un vol de démonstration à l’attention des élus locaux, des employés de l'entreprise et des médias. La région de Washington DC est la dernière étape de démonstrations en vol pour les clients civils et militaires à travers le pays.
L'appareil peut atteindre une vitesse de croisière de 200 noeuds (370 km/h) et atteindre une vitesse maximale de 232 noeuds (430 km/h) avec un taux de montée de 5500 pieds par minute.
Plusieurs pilotes ont été invités à bord du X3 au cours de ses deux précédentes étapes américaines à Huntsville Redstone Army Airfield Arsenal et à Fort Bragg Simmons Army Airfield. Le X3 est prévu pour poursuivre des démonstrations en vol militaires à Fort Belvoir’s Davison Army Airfield les 24 et 25. Il terminera sa tournée américaine le 26 juillet au Pentagone.
Corroborant la question posée par Theatrum Belli à Régis Magnac lors du salon Eurosatory 2012, Eurocopter envisage un large éventail d'applications pour cette technologie hybride notamment : la recherche et le sauvetage sur de longues distances (SAR), la surveillance du littoral maritime, les missions de patrouille aux frontières, le transport de passagers, le transport aérien off-shore, un service de navette entre les villes. Il est également bien adapté pour des missions militaires comme les opérations menées par les forces spéciales, le transport de troupe, le combat SAR et l'évacuation médicale.

Eurocopter continues its U.S. tour of the X3 high-speed hybrid helicopter today in Manassas, Va. where the aircraft performed a flight demonstration for dignitaries, local elected officials, company employees and the news media. The Washington, D.C., metro area is the final leg of flight demonstrations for civil and military customers across the country.
The tour began when the X3 made its debut at the Grand Prairie, Texas headquarters of Eurocopter’s U.S. subsidiary – American Eurocopter – which was attended by employees, elected officials, customers and industry partners. Several commercial customers from various market segments flew the X3 when it demonstrated its unique flight characteristics, which include a cruise speed of 200 knots, high rates of climb and executing high-speed maneuvers that are not routine for conventional rotary-wing aircraft. The X3 has already demonstrated a maximum speed of 232 knots at 80 percent power and a rate of climb of 5,500 feet per minute.
―We are extremely pleased to bring the X3 here to the Washington, D.C. area for the final leg of its highly successful U.S. tour,‖ said American Eurocopter President and CEO Marc Paganini. ―I am confident that the aerospace community and military leaders here will be as impressed as all of the customers who have already experienced this cutting-edge technology.‖
Several guest pilots flew aboard the X3 during its previous two stops at Huntsville’s Redstone Army Arsenal Airfield on July 9 and 10, and Fort Bragg’s Simmons Army Airfield on July 16 and 17. The X3 is scheduled to continue military flight demonstrations at Fort Belvoir’s Davison Army Airfield July 24 and 25, where guest pilots will experience the aircraft’s maturity and excellent handling characteristics firsthand. The X3 will then conclude its U.S. tour on July 26 at the Pentagon.
Eurocopter’s aircraft configuration for the X3 uses a pair of turboshaft engines to power a five-blade main rotor system, along with two propellers installed on short-span fixed wings. This concept is well adapted to missions requiring long transit flights and where speed is important, while retaining vertical lift and hover capabilities – all at a very affordable cost.
The company envisions a wide range of applications for its hybrid technology in future products, including long-distance search and rescue (SAR), Coast Guard missions, border patrol missions, passenger transport and off-shore airlift, along with inter-city shuttle services. It also is well-suited for military missions in special forces operations, troop transport, combat SAR and medical evacuation – benefitting from the combination of higher cruise speeds with excellent vertical takeoff and landing performance.
Eurocopter began X3 flight testing in September 2010 at the Istres Flight Test Center in southern France. Beyond confirming its excellent flight qualities, maneuverability, outstanding acceleration and deceleration capabilities, the hybrid demonstrator has shown exceptional climb and descent rates along with very low vibration levels – all without any need for passive or active anti-vibration systems.
