Phases:
- 1. Adaptation of the test facility
- 2. Testing of mechanical strength of the sample under inner pressure (hydro- and pneumo-pressurization).
- 3. Estimation of wall permeability of the sample using gaseous fuel and liquid fuel as a coolant at normal conditions.
- 4. Performing of hot test for following purposes:
- - Checking material capacity to withstand mechanical and thermal loads.
- - Measurements of coolant leakage (permeability) during hot tests.
- - Infrared measurements of temperature field on the sample surface.
- - Measurement of coolant heating.
