[0002] A flexible probe is a type of probe that can be bent and deformed. This type of probe is usually used in ultrasonic testing or imaging systems to adapt to complex testing environments or target object surfaces. Compared with traditional rigid probes, flexible probes have better flexibility and adaptability, and can perform more accurate testing on irregular or curved surfaces.

[0003] CN212514418U discloses an ultrasonic flexible probe testing device for projectiles, comprising: a flexible probe and a testing bracket located on one side of a rotating projectile; the testing bracket includes at least two probe fixing slots, a water inlet hole, a water outlet hole, and a protruding structure; the water inlet hole and the water outlet hole are connected to the probe fixing slots, and the flexible probe is fixed in the probe fixing slots. The flexible probe is an ultrasonic immersion phased array probe; the protruding structure is located on the back side of the testing bracket relative to the contact surface of the projectile. This invention can simultaneously detect longitudinal and circumferential crack defects, overcome key technical problems such as poor coupling of curved surfaces and imaging distortion of longitudinal grooves on standard bodies, and has a simple structure, is easy to move, and improves the efficiency and effect of non-destructive testing of projectiles.
