A water rocket is a type of model rocket using water as its reaction mass. The water is forced out by a pressurized gas, typically compressed air. Like all rocket engines, it operates on the principle of Newton's third law of motion. Water rocket hobbyists typically use one or more plastic soft drink bottles as the rocket's pressure vessel. A ...

The project started in 2016 as a successor of the Stratos II+ mission with the purpose of reclaiming the European altitude record for student rocketry, currently owned by the German team HyEnD. The Stratos III rocket is 8.2 m tall and is powered by the DHX-400 Nimbus, a 360 kNs impulse hybrid rocket engine. [15]

The group did their research on rockets from a launch site deep in the Mojave Desert. [1] In the summer of 1956, 17-year-old Jimmy Blackmon of Charlotte, North Carolina, built a 6-foot rocket in his basement. The rocket was designed to be powered by combined liquid nitrogen, gasoline, and liquid oxygen.
A steam rocket (also known as a hot water rocket) is a thermal rocket that uses water held in a pressure vessel at a high temperature, such that its saturated vapor pressure is significantly greater than ambient pressure. The water is allowed to escape as steam through a rocket nozzle to produce thrust. [1]
Liquid rocket engines have tankage and pipes to store and transfer propellant, an injector system and one or more combustion chambers with associated nozzles.. Typical liquid propellants have densities roughly similar to water, approximately 0.7 to 1.4 g/cm 3 (0.025 to 0.051 lb/cu in).
Steering during the launch phase was accomplished by four graphite rudders placed in the exhaust stream of the combustion chamber, as in the V-2, but once high airspeeds had been attained this was accomplished by four air rudders mounted on the rocket tail. Unlike the V-2, Wasserfall was designed to stand ready for periods of up to a month and ...
