Small coaxial aircraft ejection device

Abstract

The invention discloses a small coaxial aircraft ejection device, which relates to the technical field of unmanned aerial vehicle flight. The device comprises an ejection shell and a bottom plate protection plate arranged at the bottom of the ejection shell. A spring energy storage assembly and an automatic unhooking mechanism are installed in the ejection shell. A positioning connection cone is arranged at the ejection connection part; the positioning connection cone is used for fixing the coaxial aircraft in an energy storage state, the spring energy storage assembly is used for compressingand storing energy of the positioning connection cone, the automatic unhooking mechanism can achieve automatic unhooking of the positioning connection cone, then the positioning connection cone is ejected out under the energy storage effect of the spring energy storage assembly, and ejection of the coaxial unmanned aerial vehicle is achieved. By arranging the energy storage ejection mechanism, kinetic energy is initially provided for the coaxial aircraft, the take-off speed of the coaxial unmanned aerial vehicle is increased, rapid reaction take-off and landing are achieved, and the device issuitable for rapid reaction flight in some special scenes and high in reliability.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a small coaxial aircraft ejection device. Background technique [0002] UAV is an unmanned aircraft operated by radio remote control equipment and self-contained program control device. According to the classification of application fields, UAVs can be divided into military and civilian: for military use, UAVs can be widely used in aerial reconnaissance, surveillance, communication, anti-submarine, electronic interference, etc.; for civilian use, they can be widely used in aerial photography, agriculture, Plant protection, micro selfie, express transportation, disaster relief, observing wild animals, monitoring infectious diseases, surveying and mapping, news reporting, power inspection, disaster relief, film and television shooting and other fields. Classified by scale (civil aviation regulations), UAVs can be divided into micro UAVs, light UAVs, small UAVs and...

AI Technical Summary

Problems solved by technology

[0005] However, in some special application areas, such as mountainous areas with complex terrain, remote mountainous areas, and dense forests, due to the shading and interference of some objects, the communication signals and satellite signals of the terminal are weak, and normal data transmission cannot be achieved.

When performing special or normal operations, it is often necessary to look for areas with good signals everywhere to complete the data connection; or, in the dense and vast jungle, it is difficult to find areas with good signals

In today's solutions, the data signal coverage and data transmission in a specific area can be completed by using the self-organizing network, but it is often difficult for ordinary drones to fly over dense and tall jungles and reach the predetermined height of the network.
