A leading-edge correction is obtained via the method of matched asymptotic expansions to the first-order linearized solution for the potential flow past a supercavitating flat-plate hydrofoil at zero cavitation number. The composite expansions for the pressure on the plate and the shape of the upper cavity are seen to compare well with the exact solution due to Rayleigh.

Slender Body Of Revolution

SummaryThe approximate supersonic flow past a slender ducted body of revolution having an annular intake is determined by using the Heaviside operational calculus applied to the linearised equation for the velocity potential. It is assumed that the external and internal flows are independent. The pressures on the body are integrated to find the drag, lift and moment coefficients of the external forces. The lift and moment coefficients have the same values as for a slender body of revolution without an intake, but the formula for the drag has extra terms given in equations (32) and (56). Under extra assumptions, the lift force due to the internal pressures is estimated. The results are applicable to propulsive ducts working under the specified condition of no “ spill-over “ at the intake.
