The inclined plane where the investigator (astronaut) is disposed, is presented as the imitation tool for lowered gravitation levels specific to the Moon and Mars. This approach is called “inclined immersion”. The adaptation of known mathematical models of inclined plane to the specificity of solving problems is made. The realization of mathematical models in computational experiment technology is performed. The calculating research is made to investigate the influence of attachable equipment (spacesuit etc) mass and force of friction on the value of deflection angles according to the conditions of modeling of power loading on the locomotor system. The practical guidelines for compromise angles arranging are given by reference to the above conditions performing.
