Technique to Compute Parameters of Dynamics of Descent Vehicle Movement with Hard Landing onto Planet Surface

A mathematical model of the descent vehicle landing onto the planet surface is formulated with consideration for the relative motion of the payload inside the spacecraft. The software is developed to solve equations that describe this process. It is shown that the application of damping materials for the payload is necessary. Results of computations of acceleration forces of the descent vehicle case and payload are given for various parameters of approaching the surface and different types of ground.
