Took part in the Airbus Sloshing Rocket Workshop, international competition in 2024, as a part of a 3-member team, developing a water propelled rocket that would carry liquid payload. The main challenge apart from designing and testing the propulsion system, developing the rocket inside-out, was damping the sloshing loads created by the liquid payload. The entry in the competition is presented in the following document, detailing all aspects of our design.
