Wait........the Spitfire used wooden propellers? I never knew
Internet is wonderful................
"LONDON, May 23. The Royal Commission on inventions last night announced it had awarded £.15,000 to Mr. Bruno Jablonsky for his laminated wood aeroplane propellers which helped to win the Battle of Britain.
"Mr. Jablonsky, a Polish Jew, came to Britain in 1930, and founded the firm of Jablo Propellers Ltd. He did much of his experimentation on the propeller at a laboratory at the bottom of his Croydon home's garden. Finally, he perfected a plastic wood which replaced metal propellers and enabled the Government to divert much needed metal to other purposes.
"Previously it had been found impossible to produce wooden propellers which would stand the strain of such modern high-speed aircraft as the Spitfire. 'Almost all Spitfires and Hurricanes in the Battle ot Britain were fitted with my laminated wood propeller,' Mr. Jablonsky said to-day."
