The invention discloses a reliability testing device for
ablation-resistant materials, and relates to the technical field of reliability detection.
Ablation impact detection on
ablation-resistant heat-insulation materials for a short time and with a
variable load is mainly carried out. The reliability testing device for the
ablation-resistant materials is mainly composed of three components of a
combustion chamber, a spray
pipe seat and spray pipes, high-temperature and high-pressure gas generated in the
combustion chamber is used for turning by 90 degrees in the spray
pipe seat to ablate andimpact the ablation-resistant materials, and by replacing the spray pipes with different
throat diameters, the reliability of the ablation-resistant materials under the combined effect of different pressure and temperature can be simulated. The reliability testing device has a simple result and can perform ablation
impact detection on test pieces in a short time, and the device is internally coated with a heat
insulation layer, so that the service life of the reliability testing device is greatly guaranteed; and in addition, the types and sizes of propellants used in the
combustion chamber aredifferent, the ablation
impact detection under different
working pressure and time can be simulated, more comprehensive testing can be carried out on the test pieces, and the efficiency of the reliability test of the ablation-resistant materials is greatly improved.
