HYDRODYNAMIC CHARACTERISTICS OF A CAMBERED HYDROFOIL WITH A JET FLAP

The linearized problem of an infinite steady flow about a thin cambered hydrofoil with a jet flap is solved. The flow is assumed to be inviscid and incompressible and the cavitation number is taken to be zero. It is also assumed that the profile of the foil can be expressed in terms of a polynomial function. Expressions have been obtained for lift, drag, pressure distribution, pitching moment, the jet shape, and the cavity shape. Numerical results are presented for a general "polynomial" foil, and, in particular, Tulin's low drag foil to show the effects of the geometric parameters of the foil on these hydrodynamic characteristics.
