Simulation of asteroid braking in the Earth atmosphere

This article is investigated phenomenon of asteroid braking in neighborhood Chelyabinsk. Simulation of trajectory and asteroid basic parameters is accomplished on the basis of not numerous fixed video film and measurements. Calculation of hypersonic flow around asteroid is carried out before and after asteroid collapse. Possible version of asteroids synchronous braking is discussed. Trajectory data and gas dynamic functions are presented as data for definition of asteroid collapse.
