Embodiment Construction

[0038] During the re-entry process of the high-speed aircraft, its extremely high flight speed will generate high pressure in the surrounding atmosphere, coupled with the friction between the aircraft surface and the surrounding atmosphere, which together lead to the appearance of thermal ionization and chemical ionization around the aircraft surface, thus A plasma layer is created that wraps around the high-speed craft. Such as Figures 1 to 3 As shown, a device for alleviating the impact of space plasma on the reentry communication of high-speed aircraft is located in the plasma layer 2 of high-speed aircraft 1, including a strong magnet 4 and electrodes, and the strong magnet 4 is placed on the same axis as the electromagnetic wave transceiver antenna 3 The inner surface of the high-speed aircraft 1 in the direction, the electrode is composed of an anode 5 and a cathode 6, the anode 5 and the cathode 6 are respectively located on the surface layer of the high-speed aircraft...

Abstract

The invention discloses a device for relieving the influence on high-speed aircraft reentry communication by space plasma. The device is located in a plasma layer of a high-speed aircraft. The device for relieving the influence on high-speed aircraft reentry communication by the space plasma comprises a strong magnet and an electrode pair. The strong magnet is arranged in the inner surface of the high-speed aircraft located in the same axial direction with an electromagnetic wave receiving and sending antenna, the electrode pair is composed of an anode and a cathode, the anode and the cathode are located on the portions, at the two sides of the electromagnetic wave receiving and sending antenna, of a surface layer of the high-speed aircraft. The composite environment of an electric field and a magnetic field is created on a physical layer in space around the electromagnetic wave receiving and sending antenna of the high-speed aircraft, and an electromagnetic relieving layer is formed on the plasma layer of the high-speed aircraft. The problem of transmission interruption of communication signals in the process that the high-speed aircraft reenters the atmosphere is solved and the safety and real-time performance of space communication and the stability of signal transmission are guaranteed.

Description

technical field [0001] The invention relates to the technical field of space communication, in particular to a device for alleviating the influence of space plasma on reentry communication of high-speed aircraft. Background technique [0002] During the reentry flight of a high-speed aircraft, atmospheric molecules are ionized due to powerful impacts, forming a plasma layer that wraps around the outer surface of the aircraft. The plasma layer usually has a very high electron density, generally in the range of 10 15 to 10 19 m -3 Between , this value is mainly limited by the geometry and flight trajectory of the aircraft. The existence of the plasma layer will have a great negative impact on aircraft communication, causing a temporary interruption of communication signals and electromagnetic wave transmission. Generally, the interruption time will last several minutes, which mainly depends on the shape of the aircraft, re-entry angle, atmospheric characteristics and speci...
