| Résumé | This report details the study into trimming and ballasting the buoyancy engine designed by NRC-IOT. The introduction discusses the basics of a glider, as well as current gliders already in operation around the world. Design considerations are then listed and their effects on the glider noted. The design of a nosepiece and tether cable prior to testing is described. The locations of the center of mass and center of buoyancy are calculated, are related to one another, and are discussed. Section 4 includes the implementation of a system of lead weights to test the buoyancy engine's ability to position itself horizontally and to rise and fall at acceptable glide angles. Section 5 details the concept selection of battery type, size, shape, weight, and other factors. MATLAB code for communicating with the serial data communications port is discussed and results of tests are given. Future work is then discussed along with a conclusion. |
