BERP rotors

BERP rotors

BERP-rotors are rotors developed under the British Experimental Rotor Program.

The initial BERP rotors were developed in the late 1970s to mid 1980s as a joint venture programme between Westland Aircraft and the Royal Aircraft Establishment. The goal was to increase the helicopters lifting-capability and maximum speed using new designs and materials.

The initial version was BERP I, which was used on the Westland Lynx 800 helicopter. In 1986, a Lynx 800 specially modified registered G-LYNX and piloted by John Egginton set an absolute speed record for helicopters over a 15 and 25 km course by reaching 400.87 km/h (249.09 mph). T

Current applications are:
* BERP III::AgustaWestland EH101:Upgraded Westland Super Lynx
* BERP IV::AgustaWestland EH101:VH-71 Kestrel
