METHOD AND APPARATUS FOR ESTIMATING ORBITAL LIFETIME AND SURVIVABILITY OF ORBITING OBJECTS

摘要

The present invention estimates orbital lifetime and survivability of a space object. The present invention identifies no impact on reentry survivability even when not exactly obtaining true anomaly at a point in which the orbital lifetime of the space object is finished, exactly estimates the orbital lifetime of the space object, estimates a trajectory and survivability of the space object using thermochemical non-equilibrium flow considering a limited catalyst recombination rate at a wall surface of the object when calculating a heat flow rate of the space object, and is possible to complexly analyze the orbital lifetime and the survivability of the space object.
