The use of small space satellites is perspectively for the development of sciences, development of new technologies, conducting small engineering tests, and tracking global earth processes. In this article the main dependencies between various parameters of a small space satellite, which operates on outboard air, have been determined. It make possible to carry out its most optimal design. An assessment of the possibility of extrapolation in the calculations of a small number of thermalized particles to volumes close to the real number is carried out. The influence of changing the parameters of the air intake of the installation on the power of its engine and the friction force acting on the installation has been investigated. As a conclusion restrictions on engine parameters are given. They were reduced to a dependence on the diameter of the air intake.
