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 iss

Embodiment 1

[0050] see Figure 1 to Figure 9 , the unmanned power delta wing aircraft of this embodiment is mainly composed of a body 1 , a delta wing 2 , a power system 3 , a flight control system, an operation system 6 and a landing gear system 7 .

[0051] see Figure 1 to Figure 9 , the body 1 is a frame structure made of metal materials or engineering plastics, and each component of the machine is arranged on the body 1 . The delta wing 2 is arranged above the body 1 , the power system 3 is arranged at the tail of the body 1 , and the operation system 6 and the landing gear system 7 are arranged at the bottom of the body 1 .

[0052] see Figure 1 to Figure 6 and Figure 9 The triangular wing 2 is mainly composed of a triangular frame 21 and a tower 22, wherein the triangular frame 21 includes a keel 211, a beam 212 and two leading edge beams 213, and the two leading edge beams 213 and the beam 212 are fixed to each other , forming a triangle; the keel 211 extends along the longi...

Embodiment 2

[0075] see Figure 11 The difference between this embodiment and Embodiment 1 is that in this embodiment, the operation system 6 includes a spraying device, and the spraying device is connected to the front bottom of the body 1 through a mounting bracket, so that the aircraft of this embodiment is It can be used for pesticide spraying, and the spraying device is provided with a spray bar.

[0076] Embodiments other than those described above in this example were carried out with reference to Example 1.

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...
