The invention provides an array type flexible probe for ultrasonic detection of a helicopter blade and a use method, and belongs to the technical field of ultrasonic array type scanning nondestructive detection. The array type flexible probe for helicopter blade ultrasonic detection comprises an outer shell and an inner shell, the outer shell is composed of a probe front end, a probe rear end and a plurality of modules which are located between the probe front end and the probe rear end and connected in sequence, the outer shell is used for supporting and protecting the internal structure, and the inner shell is used for supporting and protecting the external structure. The probe can be bent by applying external force to the shell in the use process; the inner shell is located in a rectangular groove formed in the middle of the outer shell, and a plurality of array elements arranged in an array mode are arranged on the inner shell. Self-adaptive fitting can be achieved according to the shape of the surface of a scanned product, it is guaranteed that ultrasonic waves can vertically enter the surface of the product during real-time scanning, the modular design can be flexibly adjusted according to the length of the detection face of the paddle heating structure, the detection efficiency of the heating structure is greatly improved through one-time scanning, and higher-sensitivity detection can be achieved.
本发明提供一种用于直升机桨叶超声检测的阵列式柔性探头及使用方法,属于超声阵列式扫查无损检测技术领域;本发明中的用于直升机桨叶超声检测的阵列式柔性探头包括:外壳和内壳,该外壳由探头前端、探头后端以及位于探头前端、探头后端之间的多个依次连接的模块组成,其中,外壳用于支撑及保护内部结构,在使用过程中通过对外壳施加外力能使探头弯曲;内壳位于外壳中部设置的矩形槽中,内壳上布置多个阵列排布的阵元;能根据扫查产品表面的形状自适应贴合,保证实时扫查时超声波都能垂直射入产品表面,模块化的设计可根据桨叶加热结构检测面的长短灵活调整,一次性扫查使得加热结构的检测效率大大提高,可以实现更高灵敏度检测。
