What is the speed of the rocket?

The speed of the rocket is 7.6 to 10.8 kilometers per second.

The speed of the rocket when entering orbit is 7.6 kilometers/second; when launching into the geostationary transfer orbit, the speed of the rocket can reach 10.1 kilometers/second when launching to Earth. lunar transfer orbit; When launching into the Earth-Moon transfer orbit, the rocket The speed can even reach 10.8 kilometers/second when entering orbit.

The principle of a rocket, apparently complex, is in reality very simple. As early as the 17th century, Newton described it very clearly: if a certain mass is thrown backward at a certain speed, it will receive a reaction force. , accelerate forward.

Main classification

According to the number of steps

According to the number of steps, it can be divided into the type of stage rockets and multi-stage rockets. Since it is difficultFor single-stage rockets to achieve the cosmic speed necessary for spaceflight in practical applications, multi-stage rockets are needed to solve this problem. The first substage of the multistage rocket begins to work after launch and ignition, after the work is completed, it separates from the entire rocket. The second substage continues to push the payload into space, and so on, until the multistage rocket begins operating. the payload is sent into the predetermined orbit. Multi-stage rockets generally consist of 2 to 4 stages, with three connection methods: series, parallel and series-parallel.

By electric energy

On the basis of electric energy, it is divided into chemical energy rockets, electric energy rockets, nuclear energy rockets, solar rockets and solar rockets. photons. At present, the most commonly used rocketlized is the chemical energy rocket, which is divided into liquid propellant rocket, solid propellant rocket and solid-liquid mixed propellant rocket. As a representative of new energy rockets, the advantage of nuclear energy rockets is that the specific impulse of their engine is higher than that of chemical energy rockets, and there is only one type of propellant, which simplifies the rocket structure and is suitable for long-range rockets. missions or interstellar missions.
