Аннотация: The results of the experimental determination of the stationary aerodynamic coefficients scale models (1:63 and 1:39) frontal aerodynamic shield descent module DM-18 of the project "Exomars" are presented. The experiments were carried out in Institute of mechanics of Moscow State University in wind tunnels A-7 and A-8, the range of Mach numbers 0,2 ≤ M ≤ 2,0 at angles of attack 0≤ α ≤ 180º. There are shown the pictures of the shadow visualization circumfluence. The recalculation of the obtained experimental results on the conditions of the Martian atmosphere was performed. The obtained results allow to formulate and solve the problem of free-fall trajectory calculations on Mars surface separated from the descent module when the Mach number M = 2.
