Abstract
The invention discloses a kind of rotors for making helicopter air-flow increase, including rotor beam, windward plate, leeward plate, lift aerofoil, leeward plate is connect with plate windward, leeward plate and plate windward formed inverted triangle be located at rotor beam one end lower section and rotor beam it is affixed, lower section and the rotor beam for the other end that lift aerofoil is located at rotor beam are affixed, and leeward plate is connect by one with the connecting plate of rotor Liangping row with aerofoil is lifted.When helicopter takes off, the downward air-flow of generation reaches after plate windward in leeward plate face, and using lift aerofoil is reached after the connecting plate below rotor beam, lift aerofoil will be lifted on air-flow, while also produce certain lift.
Description
Technical field
The present invention relates to vehicle technology field, specifically a kind of rotor for making helicopter air-flow increase.
Background technology
Current helicopter will produce the prodigious air-flow for flowing to ground when taking off, these air-flows can lift on ground
Prodigious wind is played, serious influence is caused to generate the more ambient enviroments of prodigious dust.
Invention content
It is an object of the invention to overcome the deficiencies in the prior art, and provide a kind of rotation for making helicopter air-flow increase
The wing, the rotor can be such that air-flow rises, and return helicopter and provide certain lift.
Realizing the technical solution of the object of the invention is：
It is a kind of make helicopter air-flow rise rotor, including rotor beam, windward plate, leeward plate, lift aerofoil, leeward plate with windward
Plate connects, leeward plate and plate windward formed inverted triangle be located at rotor beam one end lower section and rotor beam it is affixed, lift aerofoil and be located at rotation
The lower section of the other end of spar and rotor beam are affixed, and leeward plate is connect by one with the connecting plate of rotor Liangping row with lift aerofoil.
The angle for the inverted triangle that the leeward plate is formed with plate windward is 120-150 °.
The angle that the lift aerofoil is formed with rotor beam is 30-45 °.
The upper surface of the rotor beam is set as circular arc arch.
The vertical height of the plate windward and leeward plate is 20-30cm.
Plate windward, leeward plate and the lift aerofoil, is manufactured using high temperature resistant, anti-freeze composite material.
It is provided by the invention it is a kind of make helicopter air-flow rise rotor, when helicopter takes off, generation it is downward
Air-flow after plate windward, reach in leeward plate face, using after the connecting plate below rotor beam reach lift aerofoil, lift aerofoil
It will be lifted on air-flow, while also producing certain lift, the upper surface open washing air-flow of specifically rotor beam prevents lift aerofoil from rising
Air-flow forms propulsive thrust, while plate and leeward plate form propulsive thrust windward.
Description of the drawings
Fig. 1 is a kind of transversal profile schematic diagram of rotor for making helicopter air-flow increase of the present invention；
In figure, the upper surface 4. of 1. lift aerofoil 2. rotor beam, 3. rotor beam, 5. leeward plate of plate, 6. connecting plate windward.
The present invention is further elaborated with reference to the accompanying drawings and examples, but is not limitation of the invention.
Embodiment：

Beam 2 is affixed, and lower section and the rotor beam 2 for the other end that lift aerofoil 1 is located at rotor beam 2 are affixed, and leeward plate 5 passes through one with aerofoil 1 is lifted
The connecting plate 6 parallel with rotor beam 2 connects.
The angle for the inverted triangle that the leeward plate 5 is formed with plate 4 windward is 120-150 °.
The angle that the lift aerofoil 1 is formed with rotor beam 2 is 30-45 °.
The upper surface 3 of the rotor beam 2 is set as circular arc arch.
The vertical height of the plate windward 4 and leeward plate 5 is 30cm.
Plate windward 4, leeward plate 5 and the lift aerofoil 1, is made of high temperature resistant, anti-freeze composite material.
