An actuatable porous disk (APD) with controllable porosity is presented, with the purpose of enabling future turbine cluster experiments on a small scale with dynamic collective induction control. Here, a proof of concept for the APD model is presented, including analyses of both static and dynamic behavior. To quantify the wake, the APD wake is probed with a static sensor porous disk placed at various positions in the wake. The results show that the APD thrust coefficient is strongly correlated to the porosity, and the unsteady spectrum of the wake contain clear peaks at APD actuation frequencies. This proves the capabilities of the APD model for dynamically controlling its thrust coefficient and altering its wake.
