Westland Supersonic Rotor Helicopter 1973
Only the rotors of this design were supersonic!
In the 1970s Westland designed a number of supersonic rotor helicopters, most were compound helicopters, but this design from 22 June 1973 is probably among the first proposed. The rotor diameter was 49ft 3in, loaded weight 33,500lbs and it would have three Avco Lycoming LTC.4V1 turboshafts. The plan shows armament of one Sidewinder balanced by a fuel tank on the other stub wing. Whether this design had ASW capability I'm not sure but it seems to have space for 3-4 crew so might have carried A/S torpedoes etc. in pods and a pure fighter-use seems unlikely, but self-defence might be useful as well as dealing with any Ka-25/27 it comes across in the GIUK gaps. The noise of the rotors would have been incredible and this is just one a series of amazing ideas Westland have come up with. I hope to show more in forthcoming posts.
