    I was wondering if anyone has any definitive figures on the frontal areas of various WW2 piston powered aero engines?

    All I can find are comparative figures (eg the Griffon has 6% greater frontal area than the Merlin. The Sabre had 24% greater frontal area than the Griffon)

    Also, frontal area per hp would be interesting for comparison. I know there are some USAAF and NACA documents comparing frontal drag rations and power/drag ratios for R-1830/R-2800/V-1710 engines out there, I just can't find them anymore... :oops:
