ABSTRACT
The results of an experimental investigation of the angular distribution of free molecular flow reflected from a solid body surface obtained at the VAT-103 vacuum plant at TsAGI are presented. The form of the scattering indicatrix is analyzed as a function of the energy, angle of incidence, composition of the molecular beams, and the surface material and temperature of flat models. The parameters for the Nochilla distribution function are estimated based on the results obtained on the scattering of the molecular flow and on the force impact of this flow on different samples.
