BŻ-1 GIL

Developed by the Main Aviation Institute (Warsaw), the only constructed GIL saw service until 1960 when it was irreparably damaged and subsequently decommissioned.

In addition, the institute principal Władysław Fiszdon was the only person in a team, who had ever seen a helicopter (Sikorsky R-4 in England).

[1] A fuselage structure, tail boom, auxiliary rotor and tricycle undercarriage were designed by Tadeusz Chyliński.

In 1950, it was fitted with rigid blades and an efficient simple custom-designed resonant vibration eliminator, similar to later Sikorsky designs.

[1] On 16 November 1953, the helicopter was damaged when the main rotor was bent by the wind and cut off the tail boom, thus ending the test program.

On 28 June 1957 a tail rotor gear (originally from a motorcycle) broke and it could not be replaced, consequently, the helicopter never flew again, being written off on 28 October 1960.
