Rocket ( Italian : rocchetta or Dutch : rocket- pirpirak) – a flying machine that moves under the influence of the force created by the combustion of special rocket fuel (workpiece). Depending on the type of rocket fuel, it is divided into solid fuel and liquid fuel. There are controlled and unmanaged varieties. The steering wheel can change its direction (trajectory) while flying. There are single-stage and multi-stage missiles. The multi-stage rocket consists of a spare fuel tank, an engine unit, a fuel system, controls, apparatus and more. It allows the rocket to fly at a certain stage. When the fuel supply is exhausted, the first stage will be separated from the other stages of the rocket’s flight. The initial mass of the missile can be up to several thousand tons. The missile is in military service andused in cosmonautics . The missile is launched from special launchers. The rocket is used for military purposes, space , dog work, and household needs. The creation of space rockets is associated with the names of Russian scientists KESiolkovsky, NIKibalchich, FL.Sander, VPPtushko, SPKorolyov, foreign scientists R. Goddard, G. Obert and others. [1]
