Prediction of hydrodynamic coefficients utilizing geometric considerations
Holmes, Eric P.
MetadataShow full item record
A parametric study of a body of revolution is conducted utilizing existing semi-empirical methods for the calculation of hydrodynamic coefficients. The geometry of the body is analyzed in non-dimensional length and volume parameters. The effects of varying the nose, mid-body, and base fractions of the body on the hydrodynamic coefficients are generated and illustrated graphically. Equations for the hydrodynamic coefficients are then determined from the non-dimensional parameters. The results can be used to evaluate fundamental maneuvering characteristics early in the design phase.
