Current Research

 

1) The technique of constructing three-dimensional bodies of minimum total drag and maximum penetration depth is developed within the framework of a local interaction model, which can be adopted to describe the distributions of both pressure and skin friction on the body during its high-speed motion through gases and dense media. This technique is based on the main result that, for the given base area and any specified limitations on the body size, the desired shapes are formed by combinations of surface parts whose normal makes a constant optimum angle with the direction of motion (see Figures below).

2) All the bodies constructed have the same total drag and the same penetration depth during their rectilinear motion, but they have different dynamics characterisrics when this motion is disturbed. The theoretical study of particularities of their 3D-motion is an important stage of the current research.

3) Simulation of 3D-body motion is carried out to verify results of the theoretical study.
