rakétameghajtás
Rakétameghajtás refers to the principle of propelling a rocket by expelling mass in one direction to generate thrust in the opposite direction. This fundamental concept, often described by Newton's third law of motion, states that for every action, there is an equal and opposite reaction. In a rocket, a propellant is burned or otherwise energized, creating a high-pressure gas. This gas is then expelled through a nozzle at high velocity. The force of this expulsion, known as thrust, pushes the rocket forward.
The primary components of a rocket propulsion system include a propellant, an oxidizer (which provides oxygen
The efficiency of a rocket engine is often measured by its specific impulse, which indicates how much
