Abstract

The Corner Turning Distance (CTD) can be measured with different optical diagnostic methods or also with FXR. The CTD's are important values of the detonability of high explosive (HE) charges or indicate at what distance or radius they are able to change a forward detonation in a radial detonation direction. The less sensitive HE's have an increasing problem with this phenomenon. It will be presented an overview of the different, especially the optical diagnostic methods. Their advantages and disadvantages will be illustrated on a number of typical examples. Simple tests which give only the CTD's, and more scientific arrangements allow also to define the so-called dark or dead zones. The CTD values given also good indication for insufficient initiation strength. With this method explosive trains can be also checked very well in their initiation limitations.
