METHOD OF DETERMINING THE AERODYNAMIC CHARACTERISTICS OF BODIES IN A FREE-MOLECULAR FLOW.

Abstract : A model of the body is radiated by light flux from a little aperture and one measures the indicatrix of the dispersion of the light by the surface of the model while simultaneously selecting the surface of the model in such a way that the characteristics of the reflection of the light from it would be the same as the characteristics of the reflection of the molecules of the medium in which the body is flying.
