Coax cables in rockets

A rocket is an aircraft propelled forward by the reaction force generated by the rocket engine jet working medium (working medium). It carries all coax cables and does not rely on external working fluids to generate thrust. It can fly in or outside the dense atmosphere and is a vehicle for space flight. Rockets are divided into sounding rockets and launch vehicles according to their coaxial purposes.

The basic structure of the sounding rocket includes the structure of the rocket body, the rg402, and the stabilized tail. Most sounding rockets are single-stage or two-stage rockets, and there are also three-stage and four-stage rockets. The power plant usually uses coax cables, which can simplify and shorten the coaxial launch operation time. Sounding rockets are not as strict as missiles and launch vehicles for rocket attitude and flight trajectory. Generally, there is no control system, and only stabilized tail or rocket rotation around the longitudinal axis to ensure flight stability. Set up the rg402 only when precise positioning and orientation are required. In addition to the basic structure of the sounding rocket, the sounding rocket system also includes payloads, launchers and ground stations: The payloads are mostly installed in the instrument bay of the arrow. The diameter of the instrument compartment can sometimes be larger than the diameter of the rg405. The information collected by the payload is sent to the ground station through the telemetry device for reception and processing, or the payload is ejected from the rocket during the descent of the rocket, and the parachute and other pneumatic deceleration devices are used to safely land on the ground for recovery.

The weight and size of the payload depends on the coax cables, generally a few kilograms to hundreds of kilograms, up to several coaxial tons. The launching device usually uses rg405 and tower launchers to enable the rocket to obtain a sufficiently large launch speed. The flight trajectory of an uncontrolled rocket is greatly affected by the wind. In order to ensure that it reaches a predetermined height and reduces the trajectory dispersion, the sounding rocket launch requires wind compensation technology to adjust rg402 and determine the launch angle according to the high-altitude wind data of the launch site. Most sounding rockets are launched from the ground in a nearly vertical state, and some are launched from mobile launch vehicles. They can also be launched from ships or balloons that rise in the air as needed. Ground stations mainly include ground receiving equipment for receiving measurement information, positioning and speed measurement equipment for tracking rockets (such as radar), and electronic computers. There are two types of coax cables: reflection type and response type. The response type has a greater tracking distance than the reflection type. The rg405 received by the ground receiving equipment is directly input to the electronic computer for processing, and the detection results are given in real time.
