The specific embodiment
Below in conjunction with embodiment, the present invention is done to further detailed description, but embodiments of the present invention are not limited to this.
As depicted in figs. 1 and 2, a kind of sprayer apparatus for rotor craft, comprises shower nozzle 1 and infusion channel; Described shower nozzle 1 is installed on the outer end of the propeller blade 2 of rotor craft, and propeller blade 2 is arranged on prop shaft 6 by connecting device 5, and prop shaft 6 lower ends are arranged on the body 11 of rotor craft; Propeller blade inner passage 3 is connected with prop shaft inner passage 4 is airtight, prop shaft inner passage 4 is by sealing the swivel joint 7 and hydraulic pipe 8 UNICOMs of UNICOM, hydraulic pipe 8 is Ye Xiang 10 UNICOMs with body 11 inside by control cock 9, form infusion channel.The outside of swivel joint 7 fix and with hydraulic pipe 8 seal joinings, the inside of swivel joint 7 and prop shaft 6 keep cliding friction and keep seal joining with prop shaft inner passage 4, thereby guarantee under certain pressure, the propeller blade inner passage 3 of rotation is formed to an airtight infusion channel with relative static hydraulic pipe 8, for liquid circulation.
Rotor craft vertical takeoff and landing or do not implement to spray operation when flight, control cock 9 is closed, and liquid cannot flow to shower nozzle 1 place, and aircraft belongs to normal flight.Rotor craft is when spraying overhead, region, and control cock 9 is opened, and utilizes the centnifugal force of propeller blade 2 high speed rotating generations, the liquid that is contained in liquid case 10 is pressed to the shower nozzle 1 of propeller blade 2 outer ends by airtight infusion channel, and realization sprays.
The sprayer apparatus of the present invention's design, can not need extra pressurizer and the plug-in mechanism that sprays, and shower nozzle is arranged on screw propeller outer end, spray area close with screw propeller revolving coverage method area, when aircraft flight is advanced, under rotor down draft coordinates, liquid can spray uniformly.Utilize control cock control flow and switch on hydraulic pipe, realize and spray control.
When low-latitude flying sprays operation, propeller blade 2 High Rotation Speeds, the centnifugal force of generation is pressed onto liquid shower nozzle 1 along inner passage, and after atomization, liquid completes and sprays along the rotational trajectory of propeller blade 2 outer ends, can control flow by control cock 9.Compared with general sprayer apparatus, the present invention sprays more even, utilizes screw propeller down gust that atomized liquid is blown into crop aspect, and efficiency is high, effective.
