R 44 RAVEN Robinson Helicopter Company has established a solid reputation for producing affordable helicopters engineered to a superior standard. The R44 Raven fully delivers on this reputation. The Raven incorporates as standard equipment newly developed hydraulic flight controls, which eliminate stick shake and control forces in flight. Other improvements include adjustable pedals to increase pilot comfort, and new elastomeric tail-rotor teeter hinges, which further reduce the R44's already low maintenance requirements. The Raven also sports a cleaner, updated paint scheme making it immediately distinguishable. The aerodynamic design optimizes speed and efficiency allowing for a high cruise speed of 130 mph. And, the average fuel consumption is only 15 gallons per hour. Robinson's engineering emphasis on quality and reliability continues to be recognized. Confirming this reliability, NTSB statistics show that Robinson helicopters (both R22 and R44) have fewer accidents due to aircraft or engine failure than other light helicopters. The R44's exceptional design and proven performance make it ideal for a variety of private, business, and utility applications. To allow extended flight over water, the R44 is available with either fixed or emergency pop-out floats (R44 Clipper). Also, the R44 is available fully equipped for law enforcement activities (R44 Police Helicopter) or for live, television news broadcast (R44 Newscopter). R44 CLIPPER R44 Clipper, with either fixed utility or pop out floats installed, can fly with added safety over water. Advanced float design and a low center of gravity enhance the Clipper's stability on rough seas. The fixed utility float installation adds approximately 50 pounds to the R44's empty weight. Cruise speed is reduced by less than 10 knots. The pop-out float installation adds about 65 pounds to the empty weight but does not reduce its cruise speed below a standard R44. Unlike some emergency floats, the Clipper's pop out floats have the same buoyancy as the fixed utility floats. Either float configuration allows take-offs following a precautionary or emergency water landing. LOW MAINTENANCE Reliable Engine: The dependable Lycoming 0-540 engine is derated from 260 to 205 HP (225 HP take-off) for long life and reliability. Patented Rotor Design: 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, is required between 100-hour or annual inspections. Lubrication: Teflon-lined, elastomeric, or 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. Worldwide Service: There are over 200 authorized Robinson service centers located worldwide. They offer certified Robinson parts and equipment. Professionals at every service center are trained and dedicated to meeting Robinson's stringent quality standards. ADVANCED TECHNOLOGY NEW! Hydraulic Power Controls: Designed and manufactured in-house by Robinson, the hydraulic system completely eliminates cyclic shake and control forces in the Raven. The system incorporates the latest advances in sealing and precision manufacturing resulting in enhanced reliability and reduced maintenance. Pistol Grip Cyclic Controls: Ergonomic grips incorporate two-position trigger switches for intercom and transmit. Grips also have buttons for storing and switching COM frequencies. RPM Governor: No more throttle twisting; governor automatically controls engine RPM during all normal operations. Rotor Brake: By allowing the pilot to stop the rotor quickly, the overhead rotor brake greatly reduces shutdown time and chances of injury to ground personnel. Advance Warning Devices: The instrument panel includes warning lights to indicate: low fuel, excessive main gearbox temperature, main gearbox chip, tail gearbox chip, low oil pressure, low voltage, low RPM (with a sounding horn), rotor brake engaged, engine fire, and starter engaged. Automatic Clutch Engagement: Start-up procedure is simplified and chance of an overspeed is reduced. Carb Heat Assist: Pilot workload is reduced by automatically adding carb heat when collective is lowered and reducing carb heat when collective is raised. COMFORT & CONVENIENCE NEW! Adjustable Pedals: Right side pilot pedals have been redesigned to allow two inches of fore-aft adjustment. Visibility: With comfortable 2+2 seating, front and rear seats all have 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 crossover muffler, low tail rotor tip speed, and large, cambered fin to off-load the tail rotor make the R44 a "community-friendly' helicopter. Thick acoustical foam achieves surprisingly low cabin noise levels. T-Bar Cyclic: Uncomfortable stick between knees is eliminated. Cabin entry and exit is simplified. Concealed Baggage Compartments: Each seat hinges up for access to storage areas for carry-on bags, briefcases, and other belongings. Each new Robinson R44 comes with a custom Robinson travel bag for added convenience. 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 without adding excessive noise. Voice Activated Intercom: Passengers are able to enjoy normal conversation during doors-on flights. Off-Airport Landings: High-mounted tail rotor and raised exhaust enhance safety during off-airport landings. Two-Bladed Main Rotor: Requires only one-third the hangar space of a multi-bladed rotor. STATE-OF-THE-ART-MANUFACTURING In June of 1994, Robinson Helicopter Company moved into a new 260,000 square foot manufacturing facility at the Torrance Airport. The factory was built specifically to Robinson's demanding manufacturing requirements. It is equipped with highly advanced machinery, including many computer numerically controlled (CNC) machines capable of consistently producing parts to exacting tolerances. The factory also contains an engine overhaul area where two dynamometer test cells are used for precise engine testing. Robinson was among the first American aerospace companies to meet the rigorous quality requirements and be awarded ISO 9001 certification for design, manufacture, and servicing of helicopters. A full delivery center is located onsite, including a classroom where safety and maintenance courses developed by Robinson are offered on a regular basis.
