The EC175 is powered by proven and reliable Pratt & Whitney PT6C engines.
The five-bladed main rotor and three-bladed tail rotor have new-generation blade profiles and tips. These not only offer a reduction in vibration and noise, but also provide improved lift and speed.
The Spheriflex-design, bearingless rotor head is damage tolerant and offers manual folding capability.
The EC175’s all-new main gearbox has two accessory gearboxes for double redundancy and an emergency lubrication system for 30-min flight after total loss of lubrication. De-clutch capability gives Auxiliary Power Unit benefits without the cost and weight of an additional APU.
The under floor fuel system has a four-tank standard configuration carrying nearly 530 gals (2,000 liters). Two additional tanks hold more than 130 gals (500 liters) for long range missions. The fuel system offers pressure refueling capability and is designed for safety with its simple architecture and independent systems.
The EC175 exceeds EASA CS29 crashworthiness requirements.
In addition to general fail-safe design and fully redundant systems, emergency egress capacity exceeds EASA Type IV certification requirements.
Two wide pilot doors, two extra-wide, sliding passenger doors and eight large push-out windows allow 16 passengers and 2 pilots to leave the aircraft in a matter of seconds.
Oversized front and aft emergency floatation devices are permanently “armed” in flight, and can be inflated at high speeds.
The EC175 has Sea State 6 capability with high helicopter waterline.
Two oversized 12 to 18-pax life rafts can be easily released by passengers or crew.
All emergency evacuation features and scenarios have been designed and validated by Oil&Gas industry safety advisors, operators and pilots.
The EC175’s wide cabin carries up to 16 passengers. In fact, it is the only 16 pax craft in its class. It provides unrivalled comfort and the highest levels of accessibility and visibility.
The EC175 has the highest useful volume and payload, as well as the highest performance and range in its class. Which means it can carry more passengers on more round trips per day, at a lower cost per seat, than any other 7-ton-class helicopter.
The EC175 is an environmentally friendly aircraft with low noise and emissions levels. It will come fully certified to the latest and most stringent standards. It will be full Cat. A, dual pilot. And it will be delivered, on time, in early 2012, thanks to our optimized design process.
A versatile, fully-equipped civil helicopter, the EC175 is capable of fulfilling missions in various segments, such as oil and gas, search and rescue (SAR), public services, homeland security, police, emergency medical services (EMS) and for corporate or VIP transportation.
And for even the most demanding of missions: Oil and gas crew changes and SAR configurations have been studied carefully and fully optimized with operators and end-users.
Customer advice and a logistic support analysis based on most advanced standards showed that a new maintenance approach for the EC175 would provide significant economic returns.
The benefits were achieved, first through a reduction of maintenance workload and costs, by reducing the number of maintenance tasks and their frequency. And secondly, by improving reliability of the different systems.
Advanced computer-aided design and virtual digital mock-up allowed us to analyze, from the beginning, the consequences of each potential mechanical or structural failure.
Thus, the support system was designed along with the helicopter. Result? Increased availability, reliability and safety.
With an inevitable decrease in maintenance costs.
Application of MSG-3 methodology to the elaboration of the Master Servicing Manual led to suppression of the usual “after-last-flight” visit, reduced frequency of the Technical Inspection, and complete suppression of the Major Inspection.
