Robinson R22 is a 2 seat airplane, maintained the same weight classincludes every performance records for speed, altitude and distance.And the latest model of R22 beta is still in the aircraft industry's mostaffordable price and the lowest operating cost. Beta II installation equipment is relatively substantial number of options. Standard features include a sophisticated design revolutions per minute (RPM) of thecontroller, a durable rotor brake, an auxiliary fuel system to increase its versatility and strengthen ring circuit, and a high-quality voicecommunications device driver. Beta II's clean aerodynamic design so thatit can reach a maximum cruise speed of 110 miles / hour and the average fuel consumption of only 7 to 10 gallons per hour. Engine roomprovides two mobile control of the double seat for passengers.
R22 is a typical example of design excellence. In the same grade and there is no other helicopter with its speed, safety, affordable price and lower operating costs compared to the. R22 compared to other light helicopters, have caused by aircraft or engine failure accident less. In the design process, Robinson for high-quality, raw materials and technology make it a commitment to long-term choice for flight training, radio traffic and transport monitoring, power line patrol and other requirements to the performance, security, efficiency and ease of repair of the otherapplication etc..
Design features:
Semi-rigid rotor rotor system with two blade; three hinged suspension to reduce the flexible blade with the hub, the rotor vibration and force feedback. Elastic seesaw hinge finite block, in order to prevent the start and stop when the blades in the rotor of wind with the tail beam. Type of rotor blades for NACIX63 015 (revised). Blade in the rotation for the rigid plane, the plane wave is free. Blades for the all metal bonding structure,with steel beams and front, light alloy skin and light alloy honeycomb core. There is a solid rotor blades
Tab set. The two tail rotor blades, tail beam is mounted on the left side,the structure of light alloy bonding. Rotor brake standard.
Using V belt drive transmission system, over running clutch. The main reducer and tail gear using spiral bevel gear. Using patentedmanufacturing without maintain flexible couplings in the rotor and tail rotor drive system. Rotor and engine speed ratio is 1:5, tail rotor andengine speed ratio: 28:1.
The fuselage cockpit rotor and engine frame is welded steel and light alloy main structure, a monocoque tail cone: cockpit glass skin is light alloy and steel structure.
Cruciform tail light alloy structure, horizontal stabilizer and vertical fin is fixed. In the vertical tail under elastic tail brace protection tail rotor,("seaman" type buoy).
Welded steel landing gear and light alloy skid type landing gear, withenergy absorbing device of emergency landing. "Seaman" type doublefloat / ski.
A power plant 119 kilowatts (162 horsepower) of the letter group? The Lycoming 0-320-B2C 4 cylinder flat engines, reduce the use rate of 97.5 watts (133 horsepower), installed on the host behind the bottom. Engine parts exposed, to improve the cooling efficiency and simplifymaintenance. Light alloy fuel tank in the upper left side of the rear fuselage, available capacity of 72.5 liters. Optional auxiliary fuel tankcapacity of 39.75 liters. Oil capacity of 5 liters.
The cabin has two side by side in a closed cabin seat. Periodic torquelever mounted on the two seat, in the yoke shaped piece with two control handles, can seat two persons from the helicopter. The conventionaldouble the total distance and throttle control mechanism is installed on the left side of every vice chair. The windshield glass curved shaped glass formed by the two sides of the porthole. Two seat you can put luggage cabin ventilation, heating.
Systems and equipment electrical system 12 kV DC generator. Standard equipment a Guinness KY92 communication transceiver, climb rateindicator, altimeter, quartz clock, alarm, low speed reducer temperature and metal scraps warning lights, sound equipment, anti-collision lights,night navigation lights and ground handling wheels. Optional equipment a Guinness KYI97 communication transceiver, KY53 navigation receiver,KT76A transponder and KR87 radio compass, cockpit heater and a detachable left control mechanism.
