Thanks!

Armstrong Siddley do not appear to have had a good war!

Pre-war their Tiger double row radial was hard pressed to match single row Bristols and there were repeated comments about their need to improve reliability. So much so that AS aircraft, like the Whitley, did better when re-engined with Merlins.

The Deerhound never really got going.

Then they scare the life out of Rolls with the Sapphire - the first Brit axial flow jet to really hack it (and it did very well as the J65 for Wright in the US of A)

Hi,

What about the bigger version of the Deerhound, the Boarhound that was given up when the factory was bombed in April 1941?

The Sapphire was given to AS when Metrovik were forced out of the Aero-engine Business by the main-stream cartel, as was Whittle.
It is often forgotten but the best axial-jets of the early 40’s were Metrovik’s however they were used as a backstop to develop very good ideas until the “Big boys” could stop producing their profitable range of piston engine wares and pinch the ideas. Did not RR use Metrovick’s compressor in part for the Clyde? RR even built and tested a turbofan Avon based on Metrovick and F Whittle’s work/ideas. All the wartime results etc were given to an American company and were used on some of their engines that powered some of the first American jet Airliners (when the patents ran out).

Hi Groggy,

Amazing how RR always end up on top!
