R44 Raven I
Turbine Performance/Piston Price
For those who expect excellence and appreciate value, at last there's the R44 Raven. Quite simply, the Raven delivers the performance of an expensive turbine helicopter at an affordable piston price. Its sleek design, impressive speed, and unparalleled reliability give it the competitive edge in today's fast-paced, changing environment.
Affordable luxury defines the Raven I. Standard features include a precision-engineered RPM governor, a durable rotor brake, an auxiliary fuel system for added versatility and longer range, a powerful heater/defogger, and hydraulic power controls that completely eliminate stick shake and control forces for a smooth, relaxing ride.
The Raven I's distinctive aerodynamic design allows a high cruise speed up to 130 mph and an average fuel consumption of only 12 to 16 gallons per hour. The dependable Lycoming O-540 engine is derated from 260 to 225 HP (225 HP take-off) for long life and unmatched reliability. The cabin offers comfortable "two plus two" seating with removable dual controls and no bulkhead or post between the front and rear seats, assuring exceptional visibility and panoramic views for all passengers.
The R44 Raven I is also available as a Clipper I equipped with fixed utility floats for over-water operations.
Robinson's engineering emphasis on quality, reliability, and performance has made the R44 Raven the world's top-selling helicopter. It has fewer accidents due to aircraft or engine failure than other light helicopters, and best of all, the Raven has the lowest cost per seat-mile of any helicopter anywhere.
High Reliability and Low Maintenance
Reliable Engine.The Raven's dependable Lycoming O-540 engine (Raven I) and IO-540 engine (Raven II) are derated for long life and unmatched reliability.
Patented Rotor Design.Robinson's patented tri-hinge rotor eliminates lag hinges, dampers, and hydraulic struts. Stainless steel main rotor blades resist corrosion and have thick leading edges to minimize erosion.
Inspections.No scheduled maintenance, other than oil changes, required between 100-hour inspections.
Lubrication.Teflon-lined, elastomeric, and sealed bearings eliminate most lubrication requirements.
Couplings.Maintenance-free flexible couplings are used in place of universal joints or gear couplings in the main and tail drive systems.
Controls.Primary controls are actuated by maintenance-free bellcranks and push-pull tubes, eliminating the need for control cables and pulleys.
Time-Between-Overhaul.2200 hours or twelve years approved time-between-overhaul period for the R44 engine and airframe. All life-limited components have approved service lives of at least 2200 hours.
Worldwide Service.Factory-trained technicians at more than 280 service centers throughout the world use certified Robinson parts and tools to provide quality service for R44 helicopters.
Hydraulic Power Controls.Completely eliminate cyclic stick shake and control forces in flight.
Balanced Pistol Grip Cyclic Controls.Ergonomic grips incorporate two-position trigger switches for intercom and transmit. Grips also have buttons for convenient storing and switching of COMM frequencies.
RPM Governor.No more throttle twisting; precision-engineered governor automatically controls engine RPM during all normal operations.
Rotor Brake.Allows the pilot to stop the rotor quickly, greatly reducing shutdown time and the risk of injury to ground personnel.
Advanced Warning Devices.The instrument panel includes low fuel warning light, main gearbox temperature and chip lights, tail gearbox chip light, low oil pressure light, engine fire light, low voltage alternator light, low RPM warning light and horn, plus rotor brake and starter engaged warning lights.
Automatic Clutch Engagement.Simplifies start-up procedure and reduces the possibility of an overspeed.
Carburetor Heat Assist (Raven I Only).Enhances safety and reduces pilot workload by automatically adding carb heat when the collective is lowered and reducing carb heat when the collective is raised.
Comfort and Convenience
Adjustable Pedals.Right side pilot pedals allow two inches of fore and aft adjustment.
Visibility.Comfortable "two plus two" seating provides front and rear passengers with wide, unobstructed views. No center bulkhead or post impedes visibility. Large windows in each door allow clear sideward vision from all seats.
Low Noise Level.Heavy-duty muffler, low tail rotor tip speed, and a large, cambered fin to off-load the tail rotor make the R44 a "community friendly," quiet helicopter. Thick acoustical foam achieves surprisingly low cabin noise levels.
T-Bar Cyclic.Robinson's patented cyclic design eliminates uncomfortable stick between knees and eases cabin entry and exit.
Ample Baggage Compartments.All four seats hinge up for access to concealed storage areas for carry-on bags, briefcases, supplies, and other belongings. A custom Robinson travel bag is standard equipment on new R44s.
Heating and Ventilation.An adjustable heater distributes heat to all four seats. Fresh air vents in the cabin nose and each door provide generous ventilation for all passengers.
Off Airport Landings.High-mounted tail rotor and raised exhaust provide an added margin of safety at off-airport destinations.
Two-Bladed Main Rotor.Requires less than one-third the hangar space of a multi-bladed rotor.
Voice-Activated Intercom Standard.A high-quality voice-activated intercom eliminates the need to use intercom switches during doors-on flights. Floor and hand intercom switches are included for doors-off operations.
