geh, boulton paul had an hand in unconventional aircraft, so it seems
(thinking of for example the defiant and this...)
A lot of that was because Boulton-Paul, being one of the smaller British aircraft manufacturers at that time (as did all the others) felt a lot of pressure to push the design envelope and perhaps just be different to differentiate themselves from the "big guys" and hopefully come up with a fundamentally superior product. This is why Miles came up with so many crazy projects. Boulton-Paul especially had some pressure to follow because their Defiant (which is actually pretty conventional, designed to meet an RAF-drafted "turret fighter" requirement and practically an all-metal Hurricane with a turret) turned out to be very lackluster (once again not strictly their fault, they were just following the design parameters the RAF gave to them).
And I just noticed another tidbit I feel like talking about:
The Shorts S.B.3 anti-submarine variant flown in 1950 but soon discarded due to control problems due to the Mamba turboprop efflux which destabilised the aircraft.
Yeah, in theory turbprops are great but they don't work for every practice. The biggest advantages are reliability and power-to-weight ratio, but strictly speaking they're not as thermodynamically efficient as piston engines at low altitude or as pure jets at high altitude (they're most fuel efficient at a narrow medium-altitude band that differs exactly depending on engine design, and in a lot of cases exactly at an altitude where a lot of bad weather and turbulence happens). A lot of these early turboprop combat aircraft like the Wyrven and this might've done just as well with the large radial or V/H-block WWII-legacy engines.
