Fireballs: Earth Atmosphere

Scientific paper

The precision of the local ballistic method for solving the inverse problem for the equations of motion and destruction of a fireball body in the Earth's atmosphere is improved essentially by the use of a sliding segment of variable length. Actually the variances of the physical parameters found by the local ballistic method are ±18 m/s for the entry velocity, ±81 m/s for the terminal velocity, ±3.7% and ±17% for the entry and terminal values, respectively, of the ratio of the body's mass to the area of its maximum cross-section perpendicular to the direction of motion, ±12% for the factor of conversion of the deceleration work to the light energy, and ±16% for the ablation factor.
