Abstract
Способ контроля герметичности корпуса космического аппарата в вакууме, заключающийся в том, что, при необходимости, создают давление воздуха внутри корпуса космического аппарата и вывод о наличии локальной негерметичности делают с использованием чувствительной среды, отличающийся тем, что в качестве чувствительной среды применяют индикаторные дискретные частицы, запускаемые с заданным шагом вдоль поверхности его корпуса и меняющие свои траектории под воздействием газового потока из течи, производят измерение отклонения положения мест ударов этих частиц о чувствительный экран-мишень, устанавливаемый под заданным углом для отражения их в специальную ловушку, и регулируют чувствительность измерений изменением начальных скоростей индикаторных дискретных частиц и расстояния между источником, запускающим индикаторные дискретные частицы, и экраном-мишенью.A method of monitoring the tightness of the spacecraft’s hull in a vacuum, which consists in the fact that, if necessary, create air pressure inside the spacecraft’s hull and the conclusion about the presence of local leakage is made using a sensitive medium, characterized in that indicator discrete particles are used as a sensitive medium, launched with a given step along the surface of its body and changing their trajectories under the influence of a gas stream from a leak, they measure the position deviation m Article strikes these particles on a target sensitive screen, installed at a predetermined angle to reflect them in a special trap and adjusting the sensitivity of measurements of initial velocities change indicator discrete particles and the distance between the source, discrete particle triggering indicator, and the target screen.
