What are the three basic components of the rocket

The rocket is composed of a power system, a control system and a structural system. The three systems of power device system, structural system and control system are commonly known as the main system of the launch vehicle. Whether the main system is reliable or not directly affects the success or failure of the launch vehicle flight.

The rocket is mainly composed of three major systems: structural system, power system and control system. The structural system is the body of the rocket, which protects the internal tissues; the power system is the source of life of the rocket, which is composed of the fuel part and the engine part;And the control system is like a brain, directing the rocket to control the flight speed, working mode and determine the flight target.

[Answer Analysis]: Whether it is a solid launch vehicle or a liquid launch vehicle, whether it is a single-stage launch vehicle or a multi-stage launch vehicle, its main components are structural system, power system and control system.

Three systems for car maintenance to improve car performance

1. Suggestion: Fuel system cleaning and maintenance are suitable for oil replacement. After cleaning, oil protector can be added, which can more effectively improve the service life of vehicle parts and enhance engine power. .

2. Fuel system Cleaning the fuel system can remove glue and carbon in the car. At the same time, it can effectively prevent and control harmful substances and greatly improve the performance of the car. Maintenance of the cooling system. When the car is running, the cooling system needs to be cleaned and maintained every six or eight months.

3. Maintenance of the three major systems of automobiles: maintenance There are three soft systems related to the maximum efficiency of automobiles, namely electricity, fuel and air. Jane needs to briefly introduce the three major soft systems to improve car performance, and briefly introduce the patience of each part.
