Towards the in-flight monitoring of clamp load and integrity of bolts and screws
There are two ultrasonic techniques in industrial use to evaluate the clamp load on-line and to control the fastening process. Both techniques hold high promise to enable the in flight monitoring of clamp load and integrity. The poster sketches the state of art, discusses the differences in the technical solutions and shows the complementary characteristics of both techniques. The major part deals with the needed developments towards the in-flight monitoring and hopefully stimulates the comments and suggestions of other experts.
