THE TRANSITION OF A SPACE VEHICLE, BRAKED IN THE ATMOSPHERE OF A PLANET, INTO THE ORBIT OF AN ARTIFICIAL SATELLITE AND AXIALLY SYMMETRIC OSCILLATIONS OF CYLINDRICAL SHELLS IN SUPERSONIC FLOW OF GAS,

Abstract

The transition of a cosmic vehicle entering the atmos phere with a speed greater than the escape velocity from braking ellipses into the circular orbit of an artificial satellite of the planet. It is shown that the minimum thrust, necessary for the transition is achieved when it is imparted at the moment of contact to the braking ellipse of a given circular orbit in the apoaster. A simple formula is obtained for determination of the optimum increase of speed during transition as a function of the height of the circular orbit. (Il'in). A method is given of investigating axially symmetric oscillations of cylindrical shell, making it possible to obtain an accurate solution of problem with a consideration of forces of inertia of all displacements. The method is discussed in reference to general equations of theory of shells which does not consider inertia of displacement. (Livanov)
