rakétahordozóvá

A rakétahordozó, often referred to as a launch vehicle or rocket, is a rocket-powered vehicle, structure, or device that is used to carry a payload from the surface of the Earth into outer space. This payload can consist of various items, most commonly satellites, spacecraft, or space probes. The fundamental principle behind a rakétahordozó is Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. Rockets expel mass, typically hot gas, at high velocity in one direction, generating thrust that propels the vehicle in the opposite direction.

Rakétahordozók are typically multi-stage vehicles. This means they are composed of several rocket stages, each containing its own engines and propellant. As a stage expends its fuel, it is jettisoned, reducing the overall mass of the vehicle and allowing subsequent stages to accelerate the remaining structure more efficiently. This staging is crucial for achieving the high velocities required to overcome Earth's gravity and atmosphere. The design and construction of these vehicles involve complex engineering, requiring expertise in aerodynamics, propulsion, materials science, and control systems. The successful launch and operation of a rakétahordozó are critical for space exploration, scientific research, and the deployment of communication and Earth observation satellites.
