H175

The Airbus Helicopters H175, formerly the Eurocopter EC 175, is a 7-ton class multi-mission helicopter intended for the civil market being developed by Eurocopter in conjunction with China's Harbin Aviation Industry Group, an AVIC II corporation subsidiary. The program was officially launched on December 5, 2005 during a visit of Chinese Prime Minister Wen Jiabao to France. The EC 175 development was completed in five years beginning in 2006. First flight was carried out in December 2009. Aircraft certification in both countries, France and China, as well as series production start are due in 2011. The H175/EC175 helicopter is intended mainly for offshore oil and gas missions as well as search and rescue (SAR), homeland security, emergency medical service (EMS), and passengers air transport operations. The H175 program is executed by a 50/50 joint venture with two separated assembly lines in France and China. Eurocopter and AVIC II will invest about 300 million Euro each, totaling 600 million Euro. The commercial forecast for the aircraft type was numbered at 800 helicopters over a 20-year period. Overall, this program should be worth about 10 billion Euro. According to Eurocopter, the H175 is meant to fill the gap between 5-ton Dauphin and 10-ton Super Puma/Cougar rotary-wing aircraft. As of late February 2008 Eurocopter had logged 111 commitments from customers around the world. The new medium-twin class helicopter will feature latest avionics and cockpit equipment highlighting four 6x8-in LCD displays, cabin and cockpit air conditioned, emergency floatation devices, a five-blade Spheriflex main rotor, a four-axis digital Automatic Flight Control System (AFCS), and high-energy crash absorbing airframe. It will be powered by two Pratt & Whitney PT6C-67E engines with new generation FADEC. The aircraft will have a very low vibration level minimizing internal and external noise, falling far below the latest ICAO standards. Operated by a crew of one or two-pilots it will be able to carry as many as 16 passengers at speeds of 280 km/h. Its action radius will stay above 200 nautical miles (370 km).
