Sikorsky S-56 Original Drawings

Sikorsky S.56 passenger variant ? ... https://api.parliament.uk/historic-hansard/commons/1954/may/12/sikorsky-s56-helicopter?fbclid=IwAR3NGNeA1XCptR9ophVT-Q5qfqkgcH6Vq-eZaWjo5bm2pEedTX6-I57gpF8
 
Norman Dodds, the MP asking the question doesn't seem to have had an aviation background. He does seem to have been a colourful character though.

Perhaps he was lobbying? Westland had tried to secure a licence for the S-56 in 1954 but the Ministry of Supply did not support their proposal. It took another 4 years for them to get the licences for the main transmission elements and begin their own private venture. In hindsight, had the Westminster been started 3-4 years earlier would have had a greater chance of success? A what-if question but an interesting one.

Sikorsky six-bladed experimental rotor intended for S-56 development. Anticipated that it would increase the maximum speed of the '56 by 30 knots, impressive as at the time it was the fastest helicopter in the World at 140 knots.
