According to the damage and failure mode of the Reusable Launch Vehicle (RLV)cryogenic tank insulation structure
combined with the NDT technology of adiabatic structure debonding,a technical solution of insulating structure debonding detection and monitoring was proposed based on ultrasonic guided waves. Also the adiabatic structure debonding (specimen stage) was detected in the temperature-load combined loading test
while the feasibility of the system was preliminarily measured by principle verification test
which provided support to the design
performance assessment and maintenance of RLV cryogenic tank insulation structure.
