Abstract

PURPOSE:To reduce cost, by a method wherein each of the dynamic unequilibrium vectors is measured to obatain the dynamic unequilibrium vector in a vacuum by extending each dynamic unequilibrium vector component of gaseous density up to the zero point of the density. CONSTITUTION:A testing apparatus consists of a cylindrical He container (bag), a He gas injecting port, a He gas discharging port, an oxygen density measuring instrument, etc. The dynamic equilibrium test is made by placing the He bag 1 on a satelite 6 mounted on a driving part 5 in the atmosphere. Next the He gas is injected from the He injecting port, while air is discharged from the He gas discharging port 3, in order to change the density of the atmosphere in the bag 1. To measure the density of the mixed gas in this He bag, the oxygen density measuring instrument 4 is used. In other words, the amount of the appararent dynamic unequilibrium induced by an aerial influence when the dynamic equilibrium of the body under test is adjusted is computed from the measured data in the atmosphere with different gaseous density. Thus the amount of the dynamic unequilibrium in a vacuum can be obtained at low cost.
