Bell 212 - twin-engine multi-purpose helicopter, analogue of Bell 204 / 205.

Bell 212 - multipurpose helicopter with the presence of two engines. It is a variant of the helicopter Bell 204 / 205. This air machine created an American company "Bell Textron helicopter" directly to the Canadian Armed Forces. For the first time an air unit took to the skies in April 29 1965 years. Under the contract, the Canadian Air Force handed over 70 units where they renamed CH-135. The supply of helicopters began in May 1971 years. US Department of Defense has ordered 294 instance (American Bell-212S renamed UH-1N).

In 1971 in the city of Fort Worth have launched full-scale production, and later it was transferred to Mirabel, Canada. The size, structure and composition of the equipment is very similar to a helicopter model Bell 204 / 205, but had a significant advantage in terms of reliability due to the installation of an additional motor. Bell 212 able to perform horizontal flight failure of one engine.

Modification of 212-is as follows: to increase the entire volume of the cabin and extended nose cone, thanks to the number of passengers increased. In January 72, the helicopter was certified, for which he was permitted to make flying directly over the instrument, making it more competitive. Many companies and businesses needed a helicopter for more effective implementation of geological exploration, logging, maintenance of drilling offshore platforms and more.

In June, the 1977 Bell 212 was the first of all the American helicopters, which has received a certificate confirming the possibility of piloting the instrument over the sea, the crew in this case can consist of a single pilot. In February, two years 9 cars bought in China for industrial purposes. And it is this type of helicopter was the first sold in America, Communist China.

Buildings helicopter since 1952 years intensively involved the Italian company "Agusta". Previously it has licensed. Naturally, they also started serial production of 212-th. But, in contrast to the American style, the Italian assembly staged motors Canadian production firm "Pratt and Whitney» - PT6T-3 TurboTwin-Pac. Also, it was renamed Agusta Bell AB-212. It is created by a different staffing levels, because first of all pay attention to the destination of the helicopter and the personal wishes of the customer. Italian AB-212 1971 began to build in the autumn of the year.

AB-212 piloted by one pilot. In an embodiment, the base model of the helicopter main purpose is the carriage of no more than 14 people at a time. But the highlight was the fact that it is easy to modify or stall for other purposes, even for VIP-transport. This air unit can be mounted at any optional equipment: fuel tanks, winches, floats, tap to foreign transportation of goods, ski gear and much more. Sanitary modification of the helicopter was capable of carrying 6 injured on stretchers and two medical orderlies.

Taking advantage of the experience modification helicopter "Bell" Italic engineers have developed a special version of a modification of the ASV / ASW, the main purpose of which is an active fight against submarines, surface ships and implementation of search and rescue operations. These modified AB-212 mainly located on destroyers and frigates. In 1973 year AB-212ASW entered the pilot tests in the Italian Navy, and in 1976, there were production models. Customers on this model was seven, all built around a hundred cars, and the largest customer in the amount of units 60 steel themselves Italian Navy.

ASW "Bell" in the composition of its equipment includes a search radar station with the presence of a rotating antenna on the cabin. With the system automatically I have been associated himself radar, allowing a continuous flow of images tactical situation. Present authentication system "friend or foe" station electronic countermeasures and electronic intelligence. The main element ASW - sonar, which could be used to a depth of 137 m. During sonar search of enemy submarines helicopter could be held anywhere in the hover. This was made possible thanks to the automatic control system. From aerial weapons machine could use 2 antisubmarine homing torpedoes or Mk-46 2 bomb deep type. Also, it can carry two missiles AS-12 ASW use.

But the story does not end at the helicopter Bell 212. He served as the base for the "Bell-412», which first took to the skies in August 1979 years. These phones have left a big mark in the history of the helicopter, as they are often exploited in various military conflicts, combat drug trafficking and to fulfill the tasks set by NATO and the UN.
