The David Taylor Model Basin initiated an investigative program to determine the stability derivatives of the ANSQA-13 XN-1 VDS vehicle. To achieve this objective, a full-scale model of the SQA-13 vehicle was constructed and tests were conducted on the DTMB Planar-Motion-Mechanism PMM System 1,2. The purpose of this report is to make the data immediately available to the Bureau of Ships to facilitate procurement of the Independent VDS System. A brief description of the model, test apparatus, and procedures are given and the results of the tests are presented in the form of non-dimensional hydrodynamic coefficients. A final report containing a complete analysis of the data will be issued in the near future.
