Scientific paper

According to the observed deceleration of 15 superschmidt meteors generated by iron meteoroids values of heat transfer coefficients Λ and drag coefficients Γ were evaluated assuming quasi-continuous fragmentation. It is shown that for meteoroid initial masses M < 1 g shielding by evaporating and flying off molecules can be neglected; then Λ = 1. At M > 1 g the heat transfer coefficient Λ strongly decreases by M increase reaching values of Λ ≈ 0.1 at M ≈ 10 g. A square dependence of the reactive part of the drag coefficient on the velocity is obtained instead of the linear dependence.
