RESEARCH OBJECTIVES
The Selecting and Testing Procedures and Equipment for Detecting Locations of Module
Depressurization on the International Space Station (Bar) investigation supports International
Space Station (ISS) safety by developing means and methods to detect the location of leaks.
One of the causes of leakage can be micro-destruction of the ISS pressure hull.
BAR-1
The goal of the Bar-1 investigation is the
experimental verification of the performance
and ergonomic properties of the Bar scientific
equipment set, as well as the methods of leak
locations in full-scale conditions using the
database of the background conditions. This
set of the Bar scientific equipment is designed
to detect leak locations in the ISS Russian
Segment (RS) modules, investigate the inner
environment, and identify and control
potentially hazardous zones of
microdestructive growth in the ISS RS module pressure hull.
BAR-2
The goal of the Bar-2 investigation is the formation of a database of the background conditions
based on the results of monitoring the physical environment parameters and the pressure hull
surface microconditions in zones of potential leaks.
EARTH BENEFITS
The Bar scientific equipment can be used in civic aviation and shipbuilding as a diagnostic tool
to detect ship hull microdestruction, find corrosion growth on structural elements, and assess
conformity to permissible acoustic levels.
SPACE BENEFITS
The goal of the Bar investigation is to provide safety for the ISS Russian Segment. The Bar
equipment can be used as a prototype for detecting leak locations inside the ISS RS modules
