Airbus Helicopters EC175
Airbus Helicopters EC175 Paris Air Show 2009
The Airbus Helicopters EC175 (also Avicopter Z-15) is a 7-ton class medium utility helicopter being developed by Airbus Helicopters (formerly Eurocopter Group) and AVIC. Formally launched at Heli-Expo in Houston on 24 February 2008, the EC175 was due to be certified in 2011.
A development contract for the EC175 was signed on 5 December 2005, with Preliminary Design Review (PDR) completed on 5 December 2006 and Critical Design Review (CDR) completed on 5 December 2007. Development of the EC175 was expected to cost €600 million.
During the EC175's formal unveiling at Heli-Expo 2008, Eurocopter booked a total of 111 purchase options from 13 customers, including launch customers Bristow Helicopters and the VIH Aviation Group. During the Zhuhai Airshow in November 2008, a letter of intent for 5 Z-15s was signed between HAIG and Chinese domestic general-purpose aviation company Longken General Aviation Cooperation.
First flown on the 4 December 2009, the prototype had its official maiden flight on 17 December 2009 in Marignane, France.
The EC175 held the 3km and 6km time-to-climb records for its class, ratified by FAI, at about a minute per kilometre.
The EC175 will be extensively designed and built using computer-aided design/computer-aided manufacturing (CAD/CAM). The gears and the casing of the EC175's main gearbox (MGB) have, for example, been completely developed using CATIA V5, a first for Airbus Helicopters. The use of CAD has allowed Airbus Helicopters and HAIG to create a virtual mock-up, simplifying the task of coordinating between partners based 10,000 km apart. The first EC175 airframe structure was delivered by HAIG to Airbus Helicopters Marignane in November 2008.
The EC175 is powered by two 1,325 kW (1,775 shp) class, Full Authority Digital Engine Control (FADEC)-equipped Pratt & Whitney Canada PT6C-67E turboshafts, with 5,000 hour time between overhaul (TBO) and on-condition maintenance. The aircraft has a five-blade Spheriflex main rotor and a three-blade tail rotor. The EC175's main gearbox incorporates two accessory gearboxes, de-clutchable, avoiding the cost and weight of an auxiliary power unit (APU).
The EC175 has a 16-seat interior with access through sliding doors, and jettisonable windows. The EC175's cockpit features four 6X8 inch multi-function LCD displays, plus an optional central mission display. The EC175's avionics are derived from those developed for the EC225, and include a 4-axis dual duplex autopilot, linked to the aircraft's Flight Management System.
Airbus Helicopters will have responsibility for the EC175's main gearbox, tail rotor, avionics, autopilot, hydraulic and electrical systems, doors and transparencies. Airbus Helicopters will also be the technical lead and system integrator, and will build two of the three prototypes (the first and third). HAIG will be responsible for the airframe, tail and intermediate gearboxes, main rotor, fuel system, flight controls and landing gear.
