Using mathematical modeling and numerical calculations, the features of the motion of celestial bodies in the Earth's atmosphere are studied, taking into account their oscillation around the center of mass. The flight options of spherical and elliptical meteoroids are considered at different angles of entry into the Earth's atmosphere, as well as for cases when the center of mass of the ellipsoids does not coincide with their geometric center. The influence of oscillatory motion on trajectory parameters is investigated.: speed, the angle of inclination of the trajectory to the Earth's surface, high-speed pressure, etc. It has been revealed that at small angles of entry of celestial bodies into the atmosphere, very different flight modes are possible, when the configurations of meteoroids differ from the "correct" (spherical) and the positions of their centers of mass do not coincide with the centers of their shapes

Траектории метеороидов в зависимости от их конфигурации и углов входа в атмосферу Земли

С помощью методов математического моделирования и численных расчетов изу-чаются особенности движения небесных тел в атмосфере Земли при учете их коле-бания вокруг центра масс. Рассматриваются варианты полета метеороидов сфери-ческой и эллиптической формы при различных углах входа в атмосферу Земли, а также для случаев, когда центр масс эллипсоидов не совпадает с их геометрическим центром. Исследуется влияние колебательного движения на траекторные па-раметры: скорость, угол наклона траектории к земной поверхности, скоростной напор и др. Выявлено, что при небольших углах входа небесных тел в атмосферу возможны сильно различающиеся режимы их полета, когда конфигурации метеороидов отличаются от «правильной» (сферической) и положения их центров масс не совпадают с центрами их форм
