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 Experts believe that this was due to the fact that the exterior design of the helicopter is too outdated, and in addition, a number of flight performance had a negative impact on the aircraft, including the helicopter had a small distance flight.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.
In the cockpit of the helicopter Brantly 305 can accommodate up to five people, including two pilots and three passengers. The need to control the helicopter with two crew members and a certain impact on the attractiveness of the aircraft, as in this case, the operation of the aircraft was very costly, while the efficiency was low. In addition to the transportation of people, helicopter Brantly 305 could also perform transport on his board and small goods, provided that the goods will have dimensions and a maximum take-off weight of the aircraft is not exceeded.
Powerplant Brantly helicopter 305 consists of a six-cylinder aircraft engine brand Lycoming IVO-540-A1A, having thrust in 305 hp and allows the aircraft to accelerate to speed in 175 km \ h. (Cruising airspeed). Maximum range of flight of the aircraft is Brantly 305 355 kilometers, which is a very small figure.
