In the event of the failure of one turbine, the other operational turbine can deliver its full 671kW output. These engines can produce 1,342kW.Įach engine can deliver 671kW for 30mins, or 571kW continuously during the failure of the other engine to enable the 212 to manage cruise speed at maximum payload. It consists of a combination of two PT6 power turbines driving a common gearbox. EngineĪ Pratt and Whitney Canada PT6T-3 Twin-Pac powers the main rotor. It also includes dual Honeywell Tarsyn 444 three-axis gyro units, a stability augmentation system, an automatic flight control system and a selective flight director. The instrument flight rules (IFR) avionics system includes twin allied signal KTR 908 720-channel, very-high-frequency transceivers, twin KNR 660A VOR / LOC / RMI receivers, a KDF 800 automatic direction finder, KMD 700A distance measuring equipment, a KXP 750A transponder and a KGM 690 glide slope / marker beacon receiver. "The EVS system provides flight crews with original images of terrain and runways." It uses real-time infrared sensors, signal processing and cockpit displays to improve visibility. The EVS system provides flight crews with original images of terrain, runways, aircraft and other objects. A wide-angle view aspect is also provided by adding a second FoV to enhance manoeuvring capability and situational awareness. The system incorporates narrow-angle field of view (FoV) for better resolution to detect obstacles and hazards. The external system integrates modern sensor image processing as well as active dynamic range management. The cockpit is equipped with Max-Viz EVS-1500 enhanced vision system (EVS). The seating arrangements for 13 passengers are provided in cabin and one passenger can be accommodated in the cockpit’s left-hand side seat. The Bell 212 can be configured to accommodate up to 14 passengers. The cockpit was designed for single-pilot operations. The empty weight of the aircraft is 2,961kg and the maximum take-off weight is 5,080kg. The original teetering rotor system of the Huey was used for the new design.īell 212 has an overall length of 15.5m, a width of 14.6m and a height of 3.9m. It was developed by adding an extra engine to the single-engine Huey variant. The design is based on the Bell 205 and Huey UH-1 versions.
A twin-engine configuration enhances safety, a factor that means the model is popular with commercial operators in offshore oil and gas operations. They can carry substantial loads in hot and humid weather. The Bell 212 can be configured for a range of operations including casualty evacuation, troop transportation or passenger carriage, cargo carriage, training and rescue missions. The helicopters are in service with civil and military operators from various countries including Brazil, US, UK, Canada, Colombia, United Arab Emirates, Germany, Greece, Italy, Japan, Mexico, Spain and Turkey. It was primarily marketed as a transport helicopter for civilian operators and a military variant was introduced. The helicopter took off for its maiden flight in 1968. The Bell 212 was originally developed for Canada.
