Work on designing a flying machine model 305 Brantly began the American aircraft manufacturers in 1960 year. Aircraft manufacturers intend to create a multi-purpose aircraft that can carry out transportation on its board of people and goods, which in fact, the helicopter would provide greater demand, particularly in the civil aviation sector, which for the needs of the helicopter and began to be developed.

As pervoosnovnoy base, American aircraft builders of the corporation «Brantly Helicopter Corporation» have a model helicopter Brantly B-2, which proved to be very popular among consumers, however, are not fully able to meet all the needs, as they have a small cabin, which affects the capacity of and could not effectively be used for transportation.

His first ascent into the air flying Brantly 305 model unit has made in January 1964 years, with all test test project successfully passed, however, mass production was never launched because there is no need among customers. Experts believe that this was due to the fact that the exterior design of the helicopter is too outdated, and in addition, a number of flight performance had a negative impact on the aircraft, including the helicopter had a small distance flight.

Sufficiently large size aircraft Brantly 305 had a negative impact on such indicator as the maneuverability, which ensured the shortness of the management of this aircraft, but despite this fact, the helicopter had a sufficiently high speed of its movement, which in turn is almost closed the drawback mentioned above.

The cockpit of the Brantly 305 helicopter can accommodate up to five people, including two pilots, as well as three passengers. The need to control the helicopter by two crew members also had a certain effect on the attractiveness of the aircraft, since in this case, the operation of the aircraft was very expensive, while the efficiency was low. In addition to the transportation of people, the Brantly 305 helicopter could also carry small cargo on its side, provided that the cargo will have overall dimensions and the maximum take-off weight of the aircraft will not be exceeded.

The power plant of the Brantly 305 helicopter consists of one Lycoming IVO-540-A1A six-cylinder aircraft engine, which has a thrust of 305 hp and allows the aircraft to accelerate to a speed of 175 km / h. (cruising flight speed). The maximum flight range of the Brantly 305 aircraft is 355 kilometers, which is a very small indicator.
