Abstract

We calculated the trajectory of motion of bodies falling to Earth from deep space by the example of spherical meteor. Calculations are performed for different impact parameters, the velocity at infinity and the different sizes of bodies. To calculate the drag force and heat flux during the motion of bodies in the atmosphere using the new dependence on the Reynolds number, constructed on the basis of self-similar interpolation. The possibility of destruction of meteors from the forces of pressure and heat in the atmosphere.

Keywords:

equations of motion; the dependence of the resistance areas and heat flux on the Reynolds number; self-similar interpolation
