Vector controllable aeroengine data control cable and production method thereof

Abstract

The invention relates to a vector-controllable aeroengine data control cable and a production method thereof, and particularly to ultrahigh-temperature-resistant flexible insulated cable production technology. The production method of the control cable is characterized in that firstly, enameled wire production technology is utilized for plating a mineral material mixture (2) outside each nickel-manganese-copper alloy conductor (1), wherein the mineral matter mixture is a powder mixture which is composed of 220-grade polyimide insulating varnish and nanometer-grade silicon dioxide mineral material; secondly, an out-of-conductor wire core insulating layer (3) is obtained through braiding ceramic fiber ropes which are made of zirconia alumina silicate ceramic fiber; thirdly, two insulated wire cores are intertwisted according to a pitch for forming a wire pair (4); fourthly, after a plurality of wire pairs form the cable, a shielding armoring layer (5) wraps the cable, wherein the shielding armoring layer is obtained through braiding nickel-manganese-copper wires; fifthly, an oversheath (6) wraps the shielding armoring layer, wherein the oversheath is a sheath layer which is obtained through braiding zirconia alumina silicate ceramic fiber ropes; and sixthly, preprocessing in a high-temperature vacuum environment is performed on the produced control cable.

Description

technical field [0001] The present invention relates to a control cable and its production method, in particular to a vector controllable aero-engine data control cable and its production method. Large-flow data information transmission and equipment power distribution. Background technique [0002] With the development of China's aerospace technology and the successful development of the Long March 5 high-power rocket, the Chinese people's millennium dream of "Chang'e flying to the moon" will soon become a reality. During the launch and operation of the spacecraft, it must withstand the high temperature generated by the friction of the atmosphere and the high temperature generated by the fuel of the rocket engine. These high temperatures can reach more than 1000 ℃, which will cause damage to many parts of the spacecraft. However, in order to make the flight of the spacecraft safer, it is necessary to monitor the rocket engine and the power system of the detector in real ti...

Problems solved by technology

In addition, mineral insulated cables use ceramic powder as the insulating material. The ceramic powder is too loose. Once the casing is loose and damaged, it will leak and cause the function of the wire and cable to fail.

However, the application of existing mineral insulated cables is limited due to severe vibrations during the launch and operation of the spacecraft
