työntömoottorien
Työntömoottorit are a type of rocket engine that generates thrust by expelling a propellant at high velocity. These engines are fundamental to spaceflight, enabling spacecraft to achieve orbit, change trajectories, and land on celestial bodies. The principle of operation is based on Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. In a rocket engine, the action is the expulsion of mass (propellant) from the nozzle, and the reaction is the resulting thrust that propels the rocket forward.
The propellant used in työntömoottorit can be in liquid, solid, or gaseous form. Liquid propellant engines typically
The design of the nozzle is crucial for efficient thrust generation. Nozzles are typically convergent-divergent (De
