Coaxial cable assemblies used in space rockets

Regardless of solid launch vehicle or liquid launch vehicle, whether single-stage launch vehicle or multi-stage launch vehicle, its main components include structural system (also known as coax cable), power plant system (also known as propulsion system) and control system. These three systems are called the main system of the launch vehicle. The reliability of the main system will directly affect the success or failure of the coaxial cable assemblies. In addition, there are some systems on the launch vehicle that do not directly affect the success or failure of the flight and are composed of equipment on the rocket and ground equipment, such as telemetry systems, external ballistic measurement systems, safety systems, and sighting systems. Where: The structure of the coax cable is the base of the launch vehicle. It is used to maintain the shape of the rocket, to withstand various loads on the rocket during ground transportation, launch operations, and during flight, and to install all rg402 instruments and equipment connected to the rocket systems. Combine all the coaxial cable assemblies on the arrow into a whole.

The power rg405 plant system is a device that drives the launch vehicle to fly and obtains a certain speed. For liquid rockets, the power plant system consists of two parts: propellant delivery, pressurization system and liquid rocket engine. The power plant system of the solid rocket is relatively simple. Its main part is the rg405 solid rocket motor, and the propellant is directly installed in the combustion chamber shell of the engine.

 The control system is used to control the part of the coax cable to fly normally and reliably along the predetermined orbit. The control system is composed of three parts: guidance and navigation system, attitude control system, rg405 power supply and distribution and timing control system. The function of the guidance and navigation system is to control the movement of the launch vehicle in a predetermined orbit, send the payload to the predetermined space position and make it accurately enter the orbit. The function of the rg402 attitude control system (also known as the attitude stabilization system) is to correct the pitch, yaw, and roll errors of the launch vehicle in flight, so that it can maintain the correct flight attitude. The power supply and distribution and timing control system implement power supply and coaxial cable assemblies according to the scheduled flight timing.

 The function of the telemetry system is to measure the coax cable and environmental parameters of each system during the flight of the launch vehicle, and send these parameters back to the ground through the radio transmitter on the launch vehicle, and receive coax cable by the ground receiver; the measured data can also be measured. The parameters are recorded on the magnetic recorder on the launch vehicle, and the magnetic recorder is recovered on the ground. These measurement coaxial cable assemblies can not only be used to predict the orbital parameters of the spacecraft when it enters orbit, but also can be used to identify and improve the performance of the launch vehicle. Once the launch vehicle fails in flight, these parameters are the basis for failure analysis.
