Aeronautical atomization method, atomization control system and aircraft

Abstract

The invention relates to the technical field of aviation atomization and provides an aviation atomization method, an atomization control system and an aircraft. The aviation atomization method includes: obtaining the actual rotational speed value w of the atomizer based on the first preset condition x ; based on w x The relationship between it and the set speed value w controls the working mode of the battery: when w x When it is greater than w, control the battery to enter the charging mode, and then reduce the blade angle of attack so that W x equal to W; when w x When it is less than w, increase the angle of attack of the blade, and then control the battery to enter the discharge mode. The method avoids or at least improves the influence of the flight speed of the aircraft and the input flow rate fluctuation of the nebulizer on the rotational speed of the nebulizer, so that the degree of nebulization is controllable. Especially when the w required by the atomizer is less than w x When , reduce w by charging the battery and adjusting the angle of attack of the blade x , can reduce the loss of the atomizer and flight resistance, prolong the service life of the atomizer, and reduce the use cost of the aircraft.

Description

technical field [0001] The invention relates to the technical field of aviation atomization and provides an aviation atomization method, an atomization control system and an aircraft. Background technique [0002] Aerial spraying by agricultural aircraft has the advantages of fast flight speed, high spraying efficiency, and strong ability to deal with sudden disasters, and has been highly valued in the field of agricultural plant protection. In recent years, under the vigorous promotion of my country's agricultural modernization development needs and national policies, my country's agricultural aerial pesticide application technology has developed rapidly and has become more widely used. [0003] Compared with ground spraying, aerial spraying has a larger spatial distance between spraying equipment and crops, and spraying droplets are greatly affected by factors such as ambient temperature, humidity, and wind field. In order to improve the utilization rate of pesticides, im...

Problems solved by technology

For a specific chemical liquid, when the particle size deviates from the atomized particle size required by the chemical liquid, it will cause serious environmental pollution and reduce the utilization efficiency of pesticides, thereby affecting the control effect of pests and weeds

[0006] When the flight speed of the aircraft is fixed, the input flow rate of the atomizer liquid fluctuates, causing the rotation speed of the atomizer cage to change, which in turn affects the atomization degree of the atomizer

[0007] For an aircraft equipped with a rotating cage atomizer, the atomizer will run idly when the aircraft completes spraying and returns to the flight or does not perform spraying operations, which will not only easily cause damage to key mechanical components of the atomizer and reduce its service life, but also cause The rotation of the atomizer increases the flight resistance of the aircraft, thereby increasing the energy consumption of the aircraft and increasing the cost of the aircraft
