The Simplifying Assumptions, Reducing the Strict Application of Classical Hydrodynamics to Practical Aeronautical ComputationsNACA Technical NotesperMunk, Max M.orgUnited States. National Advisory Committee for Aeronautics.1924-11engNote presenting a general method followed to simplify the numerical work in hydrodynamics, which consists of neglecting quantities of a lower order of magnitude. Four of the solutions covered in this report include the theory of the lateral air forces on airship hulls, theory of wing sections in a two-dimensional flow, theory of wings with a finite span, and propeller theory.16 p.hydrodynamicsaerodynamics
