Problems solved by technology

Since the insulator does not take anti-electromagnetic radiation shielding measures, and the transmission power of the airborne short-wave radio station is large (the output peak power is more than 100W), in the transmission state, the rich harmonic components in its operating frequency (2MHz ~ 30MHz) are easy to cause damage to the aircraft. Electromagnetic interference caused by other electronic equipment, affecting its normal work

Embodiment 1

[0030] Embodiment one: if figure 1 , figure 2 As shown, an airborne short-wave radio antenna feed insulator is mainly composed of a metal core 51 , a hat-shaped insulating cover 41 , an insulating pad 52 , a cylindrical shielding shell 53 and a radio frequency signal socket 54 . The metal column core 51 includes an integrally formed fixing part and a plugging part. The diameter of the fixing part at the upper end is larger than the plugging part at the lower end. It is transmitted to the antenna tuner of the shortwave radio station through the radio frequency feeder. The insulating cover 41 is made of phenolic plastic with good insulation and high strength. Core insert 412 for metal core. The insulating pad 52 is made of polytetrafluoroethylene, and the insulating cover 41 and the insulating pad 52 ensure that the antenna signal outside the top skin of the aircraft is insulated from the aircraft body when the metal column core 51 leads to the inside of the body. The shiel...

Embodiment 2

[0035] In the following description, the orientation "front" refers to the direction of the nose of the aircraft, and "rear" refers to the direction of the tail of the aircraft.

[0036] Such as image 3 , Figure 4As shown, an airborne short-wave radio cable antenna is installed on the top of the aircraft, between the dorsal fin and the vertical stabilizer, and is used to radiate outward or receive radio frequency radio signals in the short-wave induction band. The airborne short-wave radio cable antenna includes a first cable 1 and a second cable 2, the top ends of the first and second cables are screwed together and installed on the vertical tail of the aircraft through a connecting piece 3. The steel cables are braided by multiple strands of steel wire ropes. In this embodiment, the first steel cable 1 and the second steel cable 2 are both braided by 49 strands of steel wire ropes with a diameter of 0.2mm, and the breaking force is 2.5KN. Described connector 3 comprises ...

Abstract

The invention provides a feeder insulator and an on-plane short-wave radio station wire antenna using same. The wire antenna comprises a first steel wire and a second steel wire. The top ends of the two steel wires are connected through screwing, and furthermore the two steel wires are mounted on a vertical tail of a plane through a connector. The connector comprises an insulator, a vibration damper and an ear ring. The lower end of the first steel wire is fixed on a skin at the front end of the plane through a through insulator. Furthermore the lower end of the second steel wire is connected with a short-wave radio station antenna RF feeder wire at the back end of the plane through the feeder insulator. The feeder insulator comprises a metal column core, an insulating cover, an insulating pad and a shielding housing. The feeder insulator provided by the invention can prevent electromagnetic radiation of a short-wave radio-station antenna signal in the plane body and prevents electromagnetic interference to operation of other electronic equipment in the plane. The double-steel-wire structure of the on-plane short-wave radio station wire antenna has advantages of sufficiently utilizing a limited short-wave antenna mounting space at top of the plane body, simplifying shape structure of the wire antenna, reducing number of outer projections of the antenna, and reducing aerodynamic resistance of the antenna in flight process of the plane.

Description

technical field [0001] The invention belongs to the technical field of airborne antennas, in particular to a feed insulator and an airborne short-wave radio cable antenna using the feed insulator. Background technique [0002] The airborne short-wave radio station is a communication device used on the aircraft to realize long-distance information transmission between the air and the ground. An airborne shortwave radio station usually consists of an antenna, an antenna tuner (antenna tuner), a transceiver, and a control box. The airborne shortwave radio antenna is used to radiate outward or inductively receive radio frequency radio signals in the shortwave band. The type, structural form and component structure of the airborne short-wave radio antenna directly affect the performance of the airborne short-wave radio communication performance (communication distance, electromagnetic compatibility, communication quality, etc.). It is necessary to comprehensively consider facto...
