The dynamics of slender bodies in dense media under conditions of the local interaction model

Using a model of local interactions an asymptotic theory is constructed for the plane motion of a slender sharpened body of revolution when it is fully immersed in a dense medium and there is no flow separation at the lateral surface. Assuming that at the initial instant of time the dynamic component of the normal stress is much greater than the tensile strength, the domain of variation of the governing, parameters corresponding to asymptotically stable types of motion is found for translational motion of a body at zero angle of attack.
