Sloshing motion inside of tank of water rocket has a significant influence on the flight characteristics of the rocket Sloshing characteristics of water rocket was studied on the ground test and its influence on the flight was observed by the flight test. It was identified that rocket with conventional nozzle has large sloshing motion inside of the tank and its flight was unstable. On the other hand, rocket with newly developed nozzle has small sloshing motion and its flight was quite stable.
