An unmanned powered delta-wing aircraft

Abstract

The invention discloses an unmanned power delta wing aircraft which comprises a body, a delta wing, a power system, a flight control system, an operating system and an undercarriage system, wherein the flight control system comprises a flight actuating mechanism, an onboard control unit and a ground remote control unit; the flight actuating mechanism comprises a pitch controller for controlling the delta wing to make a pitching motion and a roll controller used for controlling the delta wing to make a roll motion; the onboard control unit is connected with the pitch controller and is used for controlling the pitching motion of the delta wing; the onboard control unit is connected with the roll controller and is used for controlling the roll motion of the delta wing; the onboard control unit is connected with the power system and is used for controlling navigational speed of the aircraft; the onboard control unit is connected with the ground remote control unit in a wireless remote control mode and is used for receiving a remote control signal of the ground remote control unit. The aircraft has the advantages that a special airport is not needed, a professional pilot is not needed, the operating safety is high, the maintenance cost is low, the effective load capacity is high, the hang time is long, and the like.

Description

technical field [0001] The invention relates to an aircraft, in particular to an unmanned powered delta wing aircraft. Background technique [0002] Agricultural aviation is an important part of modern agriculture and one of the important symbols reflecting the level of agricultural modernization. Agricultural aircraft aviation operations have the advantages of high efficiency, fast speed, strong assault capability, and good prevention and control effects, and are not limited by crop growth. The row of ridges after rowing is not clear, especially for high-stalk crops such as corn. The height of corn is generally more than 1.2m at the bell mouth stage. Spraying fungicides, herbicides, ripening defoliants, sugar enhancers, foliar fertilizers, etc., especially in hilly and mountainous areas with inconvenient transportation, sparsely populated areas or severe waterlogging, where it is difficult for ground machinery to enter the operation, aviation operations can be a good solut...

AI Technical Summary

Problems solved by technology

But manned power delta-wing aircraft also has some problems in agricultural aviation: although the control of power delta-wing is much simpler than existing fixed-wing aircraft, professional pilots are still needed to drive on board, and the safety of pilots in the operation process ( Including flight safety, the difficulty of sealing the cockpit and easily causing liquid pollution, etc.) is the primary issue; secondly, the weight of the pilot itself affects the payload of the entire aircraft, increases the weight of the entire aircraft, and thus increases power consumption. At the same time, the airborne time of the aircraft is reduced; in addition, a simple runway with a length of more than 100m is usually required, and it is not easy to find a runway that meets this condition in the farmland operation area
