Wake generation compressibility effects in unsteady lifting surface theory

15th Applied Aerodynamics Conference, 1997
The role of compressibility during the initial stages of wake formation is investigated. It is shown that only the portion of the wake which is closest to the trailing edge is important with regard to compressibility. A simple approximation is derived which determines the relative magnitude of the compressible wake length that must be used in a ...

Prediction of Propeller Hydrodynamic Coefficients Using Unsteady Lifting Surface Theory

SNAME Propellers '81 Symposium, 1981
The prediction of axial, torsional and transverse shaft vibrations of propulsion shafts in the design stage requires accurate knowledge of the hydrodynamic coefficients that describe the propeller contribution to the inertial, damping and coupling effects in the entire system.

Unsteady Linearized Lifting-Surface Theory in the Presence of a Free Surface

Journal of Ship Research, 1987
A new lifting-surface theory is developed for the computation of three-dimensional hydrodynamic pressures on thin structures in the presence of a free surface. Two interesting cases are treated: the steady case and the supercritical unsteady case. The theory is linearized and the problem is reduced to the solution of an integral equation where the ...

An improved kernel function computation in subsonic unsteady lifting surface theory

Computer Methods in Applied Mechanics and Engineering, 1985
The authors present a method for evaluating the kernel function occurring in the integral formulation of oscillatory subsonic flow about a planar lifting surface. Results obtained so far are reported to be superior to those obtained with existing methods of solution.

Unsteady Lifting Surface Theory for a Rotating Cascade of Swept Blades

Journal of Turbomachinery, 1989
A lifting surface theory is developed to predict the unsteady three-dimensional aerodynamic characteristics for a rotating subsonic annular cascade of swept blades. A discrete element method is used to solve the integral equation for the unsteady blade loading.
