In order to assess whether RTM-Worx could be a useful tool, Umoe Mandal decided to test the software using a case where significant problems had occured due to severe race tracking. The part, a blade in the rotor of a hovercraft, is shown in the pictures below. The dry spots on top (and also at the bottom) of the part are clearly visible. ![]() ![]() Note the three metal pin inserts. The reinforcement surrounding the pins has significantly different properties due to the way it was applied. This has been incorporated in the RTM-Worx model. In addition, race tracking in all the sharp corners has been included in the model by adding small runners (shown as small green lines in the animation). ![]() RTM-Worx predicts the location of the dry spots very well. Keep in mind however, that this is a matched solution. If the size of the race tracking channels and/or the reinforcement properties are changed, the result can be very different. You will have to anticipate problems like this if you use RTM-Worx before trials have been done (ideally before the mould has been made). Photographs and RTM-Worx models were kindly provided by Umoe Mandal.
