Modeling the Motion, Ablation, and Energy Deposition of a Meteoroid in the Atmosphere Taking into Account the Curvilinearity of the Trajectory.

The problem of modeling the motion, ablation, and energy deposition of a meteoroid or its fragments moving as a single body is considered. A computer program for calculating the system of meteor physics equations by the Runge–Kutta method is created and tested. The equations take into account the curvilinearity of the trajectory of the meteor body, gravity, and a change in the heat-transfer coefficient along the trajectory. Test calculations are performed for meteor bodies of various sizes moving in the atmosphere. A change in the trajectory angle with respect to the horizon depending on the initial parameters of entry into the atmosphere is shown. The effect of taking into account the variability of the trajectory angle on a change in the velocity, mass loss, kinetic energy, and trajectory of the meteoroid is estimated. [ABSTRACT FROM AUTHOR]
