Applying the method of direct statistical modeling to the rocket measurements of air density

Abstract

A new approach to the calculation of aerodynamic characteristics ofthe rocket sensor with the oncoming gas flow using the method of direct statistical modeling and software allows computing the factor of aerodynamic interaction between the instrument and the oncoming air flow and thereby linking the measured air density with the density of the unperturbed atmosphere for the Mach number range of 0-3 and Knudsen number range of 10-3 -10. On the base of the obtained results the method of air density measurement using meteorological rockets is developed.
