Embodiment 1

[0025] An ultra-low-altitude unmanned aerial vehicle is equipped with a short-wave data communication antenna, and at the same time, a satellite relay measurement and control system is installed on the aircraft.

[0026] A backup is established for airborne satellite relay measurement and control communication, and a short-wave data communication system is selected. The transceiver of the short-wave system is installed in the fuselage equipment compartment, connected with the airborne control system and other communication systems, and is designed for electromagnetic compatibility. The antenna 1 of the shortwave system extends toward the rear end of the fuselage until it reaches the rear end of the fuselage and enters the retractable mechanism 2 of the shortwave system. The antenna 1 is wound on the electric retractable shaft, and the retractable mechanism 2 is connected to the onboard control system. , to accept its command control to realize the release and retraction of the...

Embodiment 2

[0028] The utility model relates to a plant protection fixed-wing aircraft for low-altitude operation, which is characterized in that it is at an ultra-low altitude and flies for a long time during the flight phase. Such low-altitude flight makes it difficult to carry out remote measurement and control or communication. You can choose to install an airborne satellite relay measurement and control or communication system, but the system value is high and the communication cost is high, which increases the cost of using the plant protection aircraft. In order to save the cost of aircraft on-board communication or surveillance system, during the take-off or landing phase, a lower-priced line-of-sight measurement and control link is used, while in flight, a lower-priced short-wave data communication is used to provide over-the-horizon communication and monitor position information , to send an emergency command. Partially meet the air traffic control safety requirements. The sho...

Abstract

The invention discloses an airborne short wave communication antenna system design method and a system. The system adopts a folding-and-unfolding short wave antenna layout design, and a short wave communication base station is designed on corresponding ground or a ground monitoring station. When an aircraft is flying, an antenna carries out communication in an unfolded state. When the aircraft takes off, is landing, stops working and is in a non-communication phase, the antenna is in a folded state. in order to solve a problem that the antenna of short wave data communication is long and is not easy to be installed and used on the aircraft, a layout design method of a short wave antenna which can be folded and unfolded on the aircraft is provided so as to assist realization of airborne short wave communication. The short wave communication base station is designed on corresponding ground or the ground monitoring station so that a data communication demand of beyond-visual-range flightor low altitude flight of the aircraft is satisfied.

Description

technical field [0001] The invention relates to the field of aviation communication, especially the application of aviation radio short-wave data communication, and the communication application of long-distance and low-altitude flight of aircraft. Background technique [0002] In order to realize the over-the-horizon measurement and control communication of the aircraft, the use of airborne satellite relay communication is a common method. The disadvantage of satellite relay communication is that it needs to spend satellite bandwidth rental fees, and the airborne antenna and equipment of satellite relay communication are relatively large in size and weight. Especially the size of the antenna, the currently commonly used parabolic antenna makes it impossible to install on many small aircraft. Smaller phased array panel antennas are expensive. The airborne satellite relay communication system often fails, including loss of lock, or interruption, etc., and a backup emergency...
