AB - The article discusses the physical aspects and assumptions in the formulation  of the gas dynamics and thermal physics models in conditions of "Luna -  Resource" spacecraft landing on the Moon surface. It was proposed to divide  the problem into two stages: calculation of the gas phase and determination  of trajectories and heating of particles of lunar dust. The use of the  continuum equations and not taking into account the reverse effect of  particles on gas was substantiated. The calculation results of parameters  impingement exhaust jet of spacecraft propulsion system with Moon surface  are given. It was obtained that a reverse external force is added to the  streamlined surfaces equal to 196 N, the gas temperature at the bottom of  the cargo compartment reaches 2000 K, and the calculated heat flux was 400  kW. The trajectories of the particles of lunar dust was determined and it  was found that with a size of 1 μm the distance of their flight range was  3.5 km.
