Description
Technical Field
The invention relates to the technical field of satellites in the aerospace technology, in particular to a fairing wave-transmitting port arrangement method suitable for the wave-transmitting requirement of a satellite, and more particularly to a fairing wave-transmitting port arrangement method suitable for the local wave-transmitting requirement of a satellite.
Background
Compared with the new generation of carrier rocket fairing made of full wave-transmitting materials, the fairing of the active carrier rocket is not made of full wave-transmitting materials completely, so that a corresponding wave-transmitting port needs to be designed at a specific position of the carrier rocket fairing in order to meet the test requirement of a satellite on a launching tower and the remote measurement requirement of a ground measurement and control station of a launching active section of the carrier rocket on the satellite. Under the background that China is currently advancing from the aerospace big country to the aerospace strong country and the satellite business is developed vigorously, good test conditions are provided for satellites before and during launching so as to meet the urgent requirements of rapid launching of the satellites, and the problems need to be considered in the overall design process of the satellites and the carrier rockets. For the carrier rocket fairing which is not completely wave-transparent, a reasonable wave-transparent port is provided for a satellite side in the design process of the carrier rocket fairing so as to meet the test requirement of the satellite on the tower, and the difficulty is also considerable. The design of the wave-transmitting port is closely related to the layout of the satellite antenna, the position of the tower, the position of the measurement and control station, the flight attitude of the carrier rocket, the position of the ground tracking station and other factors. The existing wave-transparent port layout in China generally adopts a technology that a single antenna corresponds to a corresponding single wave-transparent port, the wave-transparent ports between satellites in different scales are designed in a large difference, and a systematic method is not formed, so that the design process is time-consuming and labor-consuming, the requirements of rapid testing and rapid transmitting of the current satellite cannot be met, and the fairing has many openings and unreasonable positions and directions, and further the mechanical property of the fairing is influenced. The existing method is difficult to meet the design and emission requirements of the current satellite, and provides a rigorous restriction requirement on the wave-transmitting port design of the satellite on a fairing. At present, the published documents and data do not describe the design method of the wave-transparent port. Only discloses a utility model patent of aircraft fairing shell (grant publication number: CN202130570U), which provides a honeycomb sandwich fairing shell structure made of glass fiber panel and aramid paper honeycomb, and the fairing shell has the functions of wave transmission, bearing, light weight, thermal protection, exhaust and the like by arranging air holes at specific positions. The method is a fairing shell design method from the perspective of composite material application and reduction of assembly workload. However, the main body of the fairing of the current domestic active carrier rocket still adopts an aluminum alloy riveted structure mostly from the aspects of mechanical bearing performance and thermal protection performance. In order to meet the requirements of ground test and active section tracking remote measurement of a satellite, a corresponding wave-transmitting port needs to be designed according to the specific position of the antenna position on the satellite on a fairing on the premise of ensuring the mechanical property of the fairing. This document therefore belongs to a different technical field than the inventive method described herein.
