Robinson R44 Raven II

The Robinson R44 Raven II helicopter has become one of the most successful Robinson models. This device is equipped with an IO-540 Lycoming injection engine, which has more power, it allows you to improve altitude characteristics, increase the payload, as well as the speed of the helicopter. R44, Raven II is also available in IFR Trainer, Newscopter and Police Helicopter.

The engine can reduce power to 245 hp within 5 minutes, up to 205 hp in continuous operation. Such abilities guarantee a longer service life of the power unit and low maintenance costs. In addition, the Robinson Raven II helicopter, compared with Raven I, has a 45 kg increased take-off weight, increased static ceilings IGE and OGE (in the zone of influence of the earth, or outside it). And also completely eliminated problems with the carburetor and its icing.

Another major improvement of the R44, Raven II, Robinson model was noise reduction. The modification of the design of the rotor blades and tail rotors made it possible to make the helicopter quieter. Both rotors are equipped with blades with noise-canceling end caps, which reduces the noise value during flight by 1 dB. The rotor blades also have a larger surface area to increase the payload.

Features of the Robinson R44, Raven II rotorcraft: The rotor blades have an increased area, which creates greater lift, thus reducing vibration. The rotor and tail rotor blades have new aerodynamic end caps, they allow you to reduce the noise level (at an altitude of 150 m) by 1 dB - and this, despite the increased take-off weight. The standard 28-volt electrical system provides good start-up characteristics in any weather and allows you to use excess power for additional equipment.
