| Abstract | The wake survey experiment is used to profile water flow around a ship's propellers. This is done by positioning pressure sensors at various locations using a two axis stage. Two Soloist motion controller manufactured by Aerotech, with each controller operating a single axis motor, controls the stage. The Wake Survey Positioning software provides a user interface to the controllers and allows execution of a runfile. The runfile contains a list of points where pressure data is to be collected. Typically there is insufficient tanks space to complete all the points in a single run, therefore points are organized into multiple runs. The Wake Survey Positioning software contains several software components that interact together to perform a wake survey. These components are responsible for communications with the controllers, operations with the runfile, and application support operations such as configuration management. Components are also present for decoupling the model from the graphical user interface. Additionally, two programs run the motion controllers that provide status feedback and analog output of positional information. This report will discuss design of these modules and operation of these modules. |
