Abstract

The purpose of this project is to research, design, and build an ionic wind thruster. The process that our group took to be able to complete this task began with understanding the software and concepts required to fully design our system. The understanding of these concepts helped guide the group in making design choices on the airfoil which was chosen to be a symmetrical design due to no reduced drag and little to no lift. The next decision that was made is for the distance between the electrodes, which was found using our distance apparatus shown in Figure 18. This helped us determine the best distance to find the greatest electric field around the cathode or the wire. The last design choices that were made were the housing design of the cylinder and inlet funnel. A cylinder was chosen for the edgeless design and the inlet funnel to help airflow between stages. During the testing portion of the project the initial data that was collected was used as proof of concept that we would be able to obtain force measurements. The next step is to amplify this force measurement to see what results a single stage would output. After this data was gathered the group began making multiple various tests while using an anemometer to find the exit wind velocity. Throughout these tests the group varied the type of conductive plating on the anode airfoil, 6 different transformers, 3 different wire distances, and 3 different number of stages. The final result that our group found was that the ideal set up for the thruster system is using the copper tape plated on the airfoil, 1.6 cm gap distance between electrodes, and 2 stages.
