Description
Summary:The literature on model testing with a tail sting support was reviewed for its application to submarine experiments on the Marine Dynamic Test Facility (MDTF) proposed for the Institute for Marine Dynamics, St. John's, Newfoundland. A number of flow mechanisms for both static and dynamic sting interference are discussed in this context, but because of the unique features of the MDTF their relevance is not always clear-cut. Other sting-related issues such as deflection under load and vibration are briefly discussed. It is concluded that sting support for large submarine models on the MDTF is feasible for acceptable levels of interference without elaborate correction procedures. Some recommendations are made for MDTF implementation.
