Correct, both of the project drawings posted by PaulMM were powered by the Goshawk. The change to PV-12 (Merlin) occurred right at the end on 1934 in a version of the Type 300 project design that does not appear to have been survived. This is the project that was approved by the Air Min and served as the true basis for the Spitfire.airman said:On page 10 of British Secrets Projects report that Supermarine Type 300 was projected to be powered with Goshawk engine : the same of Supermarine Type 224 ( https://en.wikipedia.org/wiki/Supermarine_Type_224 ) .
I was unaware that this early version of the type 300 used the type 224 fuselage, as you say, not ideal.Schneiderman said:The first drawing has been in circulation for a long time, I think it first appeared in a book named Spitfire by Taylor and Allward in 1946.
The Type 224 fuselage, which was retained for this early Type 300 project was basically of square section from the firewall bulkhead rearwards and not ideal for a high-speed interceptor, later iterations were a big improvement. As for the bubble canopy, when did technology reach the point when it was possible to blow large, optically distortion-free plexiglass items? Not in 1936 for sure, but it is an interesting thought.
Oh, my! That's the trouble with this forum site. My must-get list grows ever bigger as my wallet shrinks ever smaller!All covered in Beyond the Spitfire, to be published on 2nd May http://www.secretprojects.co.uk/forum/index.php/topic,26604.0.html
