FIELD: invention refers to testing technique and may be used for control over insulation of body of space apparatus and searching place of leakage from compartments of space apparatus in conditions of orbital flight.
SUBSTANCE: invention is directed on simplification of diagnostics of non-insulation of body space apparatus, increase of accuracy and reduction of searching time of place of leakage This result is achieved due to the fact that air pressure is made at necessity inside compartment and blasting of parts of body of space apparatus is made with test fine-dispersed substance. Filming of process is conducted. About presence of local non-insulation they judge according to changes in lines of flow of test fine-dispersed substance under impact of air flowing out of body.
EFFECT: simplifies process of finding leakage in space apparatus on orbit.
