Airplane Performance as Influenced by the Use of a Supercharged Engine (open access)

Airplane Performance as Influenced by the Use of a Supercharged Engine

"The question of the influence of a supercharged engine on airplane performance is treated here in a first approximation, but one that gives an exact idea of the advantage of supercharging.

The aim is to find the difference of the ceilings reached in the two cases" (p. 1).
