| Description |
In 1945, the inventor Newby O. Brantly founded the Brantly Helicopter Corporation. Inspired by the Sikorsky VS-300 prototype, he started working on the Brantly B-1. However, this machine never reached the market, as its coaxial rotorhead design was too complicated and heavy. Nevertheless, the design proved to be useful when it came to acquiring the know-how that was used to create the lightweight, two seater Brantly B-2 model.
This model has a conventional design with its main and tail rotor configuration. The main rotor blades use a double set of flapping hinges, one near the rotorhead and the other at approximately 40% of the chord length. This construction gives the B-2 a smooth ride.
In 1958, the US army ordered five B-2 models, which were designated as the YHO-3. However, they were sent back after the army decided that the machines were too small for military purposes.
The B-2B version has been produced for more than six decades now. This clearly demonstrates its strong design, which still appeals to a small but loyal customer base.
During its lifetime, the B-2B design and production licences have changed hands many times. At the time of writing (2014), the machine is manufactured by Qingdao Haili Helicopters Co. Ltd.
