Well, lets talk about scoops now. Hurri had a belly scoop which had a back door. Wondered if Mustang team borrowed from the hurri design. Tony had a belly scoop as did Yak 3.
Question 1, was it really more aerodynamically efficient to put it under belly as oppsed to chin?
Mustang scoop was lowered to escape dirty boundary layer. Corsair & Yak had wing root scoops. Which look like best idea of the lot.
Spit scoops look worst. P-40 & Typhoon chin scoops likewise look very unaerodynamic.
