The Brantly B-2 is an American two-seat light helicopter produced by the Brantly Helicopter Corporation.

Design and development[edit]

After the failure of his first design, the Brantly B-1, Newby O. Brantly decided to design a simpler and less complicated helicopter for the private buyer. The B-2 had a single main rotor and an anti-torque tail rotor and first flew on 21 February 1953. This was followed by an improved second prototype that first flew on 14 August 1956.

The B-2A was introduced with a modified cabin, and the B-2B had a larger 180 hp fuel-injected engine. The B-2B has a three-bladed articulated main rotor and an all-metal fuselage, it can be operated with skid, wheel or float landing gear. The piston engine is fitted vertically in the fuselage behind the cabin.

Operational history[edit]

The basic design has remained in production for over 50 years.[1] The United States Army order five B-2's (designated the YHO-3) to be evaluated in the Light Observation Helicopter competition in 1958, although it lost the bid, the Army operated the H-5T unmanned variant as target from 1986.[4] Introduced in the early 1970s, an improved larger version with five seats was designated the Brantly 305.[5]

Variants[edit]

Survivors[edit]

A B2B belonging to the Flying Gyrocopter and Old Aircraft museum at Midden-Zeeland, Netherlands was reportedly about to fly again November 2009.[9]

A Greek road-assistance company,named EXPRESS SERVICE based in Thessaloniki,operated a B2B Brantly-Hynes helicopter for several years. That helicopter started flying in 1978 and had the Greek registration number SX-AHH. First captain was the pilot Kaltekis Spyridon.
