Embodiment Construction

[0018] 1. Mechanical interface interchangeability design steps

[0019] (1) Installation interface

[0020] Install TWT and EPC with different mechanical dimensions on one base, and unify the mechanical dimensions and installation interfaces of the two product installation bases, such as figure 1 with figure 2 shown.

[0021] (2) Design steps of structural plate heat pipe layout

[0022] Since both TWT and EPC are components with high heat consumption, the design requirements should be aligned with the embedded heat pipes of the satellite structure board to ensure normal heat dissipation. Therefore, adjust the layout of TWT and EPC on the installation base plate to ensure that the distance between their centerlines is consistent and can be aligned with the heat pipe, such as image 3 shown.

[0023] (3) Design steps of antenna waveguide output interface

[0024] The output of the TWT is a waveguide interface, which is connected to the transmitting antenna through a sect...

Abstract

The invention provides an interchangeability design method for a domestic satellite-mounted travelling-wave tube amplifier and an imported satellite-mounted travelling-wave tube amplifier. The method comprises a step of mechanical interface interchangeability design, a step of input excitation interchangeability design and a step of usage pattern interchangeability design, wherein the step of mechanical interface interchangeability design comprises enabling installing interfaces of two travelling-wave tubes to be consistent with each other, be consistent with heat pipe layout interfaces positioned on a satellite structure boards and be consistent with antenna waveguide output interfaces; the step of input excitation interchangeability design comprises adjusting intensity of input excitation signals by externally connecting a fixed attenuator so as to meet the requirements of excitation of different saturation points of the two travelling-wave tubes; and the step of usage pattern interchangeability design comprises adding movement options of instructions such as starting / shutdown, feeding low pressure and discharging low pressure in operations schedule design so as to meet the requirements of two products for different usage patterns. According to the interchangeability design method, interchanging usage of the domestic travelling-wave tube amplifiers and the imported travelling-wave tube amplifier can be achieved, and flexibility in product matching in a subsystem scheme is guaranteed. The interchangeability design method is already applied in some satellite data transmitting subsystem.

Description

technical field [0001] The invention relates to a traveling wave tube amplifier, in particular to a design method for the interchangeability of domestic and imported traveling wave tube amplifiers carried by space. Background technique [0002] In order to promote the localization process of satellite-borne traveling wave tubes and take into account the requirements of on-orbit reliability, the power amplifier stage of a satellite data transmission transmitter adopts the combined configuration of "import + domestic". Due to differences in design schemes and technical levels, there are certain differences between the two products. In order to simplify the interface with the whole star and the product backup scheme, it is hoped that the two products are designed to be interchangeable. [0003] After comparative analysis, the main differences between the two products are reflected in: traveling wave tube (TWT) and power supply (EPC) mechanical interface, number and location of...
