Specific implementation mode
Embodiment 1：
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of flying disc type unmanned helicopter provided in this embodiment, including gas ejecting system,
Control mechanism and auxiliary body, the gas ejecting system include air source mechanism and jet mechanism, and the control mechanism is mechanical steering
Control mechanism；The jet mechanism includes rack 8, and double threaded screw 6 and connection ring 7 in communication are equipped in the rack 8,
7 side of the connection ring is equipped with upper end flexural pivot 4, and 8 lower end of the rack further includes lower end flexural pivot 4 and nozzle 2, and the nozzle 2 is
Tapered runner nozzle.
The air source mechanism includes piston type air compressor, and the piston type air compressor includes the cylinder for combining connection successively
11, piston 13, piston rod 12, sliding block 14 and connecting rod 15, and 11 outside both sides of the cylinder are respectively equipped with air bleeding valve 9 and inlet valve
10.The gas ejecting system further includes a nozzle swing mechanism 19, and the nozzle swing mechanism 19 is outer including dovetail slide block 16, revolution
Cylinder 17 and revolution ellipse 18.The control mechanism is one of component electronic control mechanism or mechanical steering control mechanism.It is described
Auxiliary body includes external agency 1 and lower support mechanism 3.
The technology path being different from the prior art in the present embodiment is：
(1) air source mechanism：The pressure generated using air compression is sprayed by nozzle provides power source and defeated for helicopter
The vital point for going out mechanism is how air is changed to flying disc type helicopter required pressure in the case of normal pressure 0.1MPa
The advantages of power, piston type air compressor are the first choices in present design, piston type air compressor is simple in structure, service life
It is long, and large capacity easy to implement and High voltage output.
(2) jet mechanism：Piston type air compressor compressed air is by certain auxiliary element by the air of compression
It sprays to generate thrust by nozzle, the species structure of nozzle is very more and workmanship manufacture is fine, should select in design process
With more suitably.
Technical principle is as follows：
Mechanical transmission structure disclosure satisfy that the requirement of helicopter as the structure for having degree of precision to transmit under calculating.
Enable that the up and down of flying disc type helicopter, move forward and backward state of flight, is connected by flexural pivot.If flying disc type is gone straight up to
Machine up and down are that nozzle vertical frames are that helicopter keeps horizontality, by changing the blowing force of nozzle to make helicopter
Customer service gravity and resistance reach decline or rising.When needing advance, retreating flight, double threaded screw pulls under force
Connection ring makes the upper end of nozzle generate drift angle under the active force of connection ring, makes the blowing force of nozzle that the variation in angle have occurred,
Flying disc type helicopter forward-reverse is driven to generate component.The extreme position of nozzle, because flexural pivot maximum deflection angle is 14 °,
I.e. the beat greatest limit in beat of nozzle is 14 °.In this case, the blowing force force analysis of nozzle has X-direction to winged
The advance of dish-style helicopter brings thrust, and flying disc type helicopter, which is in, if Y direction component is more than its own gravity rises advance shape
State；Flying disc type helicopter is in steady and advances if Y direction component is equal to its own gravity；If Y direction component is less than itself
Then flying disc type helicopter is in landing forward travel state to gravity.
It is living by the link transmission of connection when air compressor external motor drives the bent axle rotation of piston compressor
Plug just moves reciprocatingly in the cylinder, and week can then occur for the swept volume being made of cylinder inner wall, cylinder head and piston-top surface
Phase property changes.From cylinder head when setting in motion, the swept volume numerical value in cylinder becomes larger the piston of piston compressor gradually,
At this point, forming a draught head inside and outside cylinder, to generate pressure, lead to gas along air inlet pipe, push intake valve open and into
Enter cylinder, until when swept volume changes to maximum, intake valve is closed；When the piston reverses direction movement of piston compressor, gas
Swept volume reduces in cylinder, and gas pressure increases, and when inner pressure of air cylinder reaches and is slightly above pressure at expulsion, air bleeding valve is opened,
Cylinder, until piston motion to extreme position, exhaust valve closure is discharged in gas.
The utility model is not limited to the above embodiment, it is all using structure similar to the utility model and its method come real
All embodiments of existing the utility model aim are within scope of protection of the utility model.
