Description

From Summary: "The linearized theory of Tulin and Burkart for two-dimensional supercavitating hydrofoils operating at zero cavitation number is applied to the derivation of two new low-drag configurations. These sections were derived by assuming additional terms in the vorticity distribution of the equivalent airfoil; in particular, three and five terms were considered. A simplified calculation of the location of the cavity boundary streamline for arbitrary configurations is also presented."

National Advisory Committee for Aeronautics Collection

The National Advisory Committee for Aeronautics (NACA) was a U.S. federal agency founded on March 3, 1915 to undertake, promote, and institutionalize aeronautical research. On October 1, 1958 the agency was dissolved, and its assets and personnel transferred to the newly created National Aeronautics and Space Administration (NASA).
