Bell CH-146 Griffon – Canadian-American military helicopter project, developed in 1992 by the aircraft manufacturer Bell Helicopter.

The helicopter model Bell CH-146 Griffon began to be developed jointly by American and Canadian engineers in the late 80s of the last century. As a reference base, aircraft manufacturers from Bell Helicopter used the Bell 412EP helicopter model, which is very clearly seen in a similar design, however, in terms of flight performance, the two aircraft are radically different from each other.

Aircraft Bell CH-146 Griffon is a military multi-purpose helicopter, mainly used to provide fire cover from the air, the transfer of small groups of military personnel, as well as for special operations. Thanks to a number of technical improvements, this aircraft became significantly more maneuverable and efficient, however, despite this fact, the production of the model became very limited – for the very production period, which lasted from 1992 to 1997, only 100 aircraft were created by American aircraft developers apparatuses.

The helicopter model Bell CH-146 Griffon passed its first tests in 1992, and due to the fact that no deviations from the parameters proposed by the developers of the future aircraft were detected, the project was decided to go into serial production.

Onboard, the aircraft model Bell CH-146 Griffon can carry up to 13 people, including three crew members (two pilots and one flight engineer), as well as 10 military personnel. If the helicopter is supposed to be used as a medical military aircraft, or as an evacuation aid, only 6 people can be accommodated in the cockpit. Due to the presence of a sufficiently large free space, the Bell CH-146 Griffon helicopter can transport up to 2150 kilograms of payload on its board.

Helicopter model Bell CH-146 Griffon is a good means of fire cover and suppression of enemy fire. The armament of this aircraft can be used:

  • 20 mm. aircraft gun to combat unarmored and lightly armored enemy vehicles;
  • 7.62 mm machine guns. installed in the doors of the helicopter;
  • 7.62 mm automatic machine gun.

The propulsion system of the Bell CH-146 Griffon helicopter includes two Pratt & Whitney Canada PT6T-3D gas turbine engines, each of which has a power of 900 hp, which provides the aircraft not only with high cargo capacity but also a rather high speed of movement up to 260 km \ h, while the maximum flight range of this aircraft is limited to a distance of 660 kilometers.
