Low-altitude flight operation unmanned aerial vehicle and control system and application thereof

Abstract

The invention discloses a low-altitude flight operation unmanned aerial vehicle and a control system and application thereof. Buffer mechanisms of a main undercarriage supporting column and a front undercarriage supporting column are designed and mounted on a force bearing structure on the outer side of a fuselage (1), the lower ends of the main undercarriage supporting column and the front undercarriage supporting column are connected into a slide-type undercarriage (2) structure, and the gliding ratio is increased through the high lift-drag ratio aerodynamic force design. A low-altitude crash prevention technology, a low-altitude link communication technology and an unmanned aerial vehicle system technology are integrated, the pneumatic and dynamic overall layout design of the fixed wingunmanned aerial vehicle suitable for low-altitude operation is adopted, and the new-layout unmanned aerial vehicle is suitable for low-altitude operation such as agricultural aviation plant protection and safety flight.

Description

technical field [0001] The invention relates to a fixed-wing unmanned aerial vehicle for low-altitude flight operations and its control system and application, and belongs to the application of general aviation in the fields of agricultural plant protection, maritime search and rescue, and aviation geophysical exploration. Background technique [0002] Agricultural plant protection has been sprayed by general aviation aircraft for decades, and it is a typical low-altitude operation application. my country has carried out aircraft pesticide spraying operations since the 1950s, and only has more than 200 agricultural special-purpose general aviation aircraft, including domestically produced Y-5, Nong-5, Y-11, and Y-12, as well as aircraft imported from abroad, etc. . Foreign agricultural plant protection general aviation aircraft are larger. In recent years, agricultural plant protection has explored the use of new agricultural plant protection technologies such as manned hel...

AI Technical Summary

Problems solved by technology

However, manned fixed-wing general aviation aircraft is technically difficult to perform low-altitude flight for agricultural plant protection. First, it is difficult to avoid obstacles when flying at a low altitude of 3-20 meters, which poses a great risk to flight safety

Second, long-term ultra-low-altitude flight, the driver is prone to fatigue, which not only causes flight safety hazards, but also makes it difficult to improve operational efficiency
