METHOD OF SPACECRAFT AIRFRAME TIGHTNESS CONTROL

摘要

FIELD: aircraft engineering.SUBSTANCE: invention can be used for spacecraft airframe tightness control in flight or in vacuum tests. Air pressure is developed inside spacecraft airframe. Airframe parts are blown with trial fine substance with small full sublimation time under test conditions (for example, carbon dioxide in solid state). Local leaks are revealed by registration of variation in lines of flow of completely evaporating trial fine substance under effects of gas outflowing from airframe.EFFECT: accurate and adequate detection of leaks.1 dwg
