A question for anyone familiar with Armstrong Siddeley engine projects from the '30s, especially the 'dog' types.
The attached two images are from Armstrong Whitworth patents for cooling ducts for air-cooled engines buried within the wing structure. The first, applied for in 1935, shows a three rows of five cylinders, so that would be the Hyena. The second, from 1938, shows six rows of four cylinders, the four being in a flattened 'X' configuration. The patent is quite specific to this form of engine layout so I would think that it was designed to deal with a planned engine type, presumably one from Armstrong Siddeley. None of the 'dog' projects I am aware of had such a layout.
Any suggestions?
