I have been working on a water jet powered UAV for MIT’s 2.017 Class. I had this idea upon being interested in the stability and control of conventional quadrotor based UAV systems as well as excited about the water jetpack systems such as Jetlev (http://www.jetlev-flyer.com/) that many recreational water sports enthusiasts use. The combination of the two has motivated me to work on building a quadjet, or an autonomous water based drone.
Below is a Render of the Solidworks Model of the Quadjet
Below is a picture of a preliminary test of the Quadjet floating. It is tied off to a string so it does not go unstable and fly away. Integrated controls are currently the focus of the project.
