Description
Technical field
A kind of rotor wing tip fusion lift flying barrel device is the utility model is related to, especially suitable for the straight of ABC rigid rotors
The machine of liter or gyroplane, belong to helicopter or gyroplane airmanship field.
Background technology
Power is obtained using ABC rigid rotors on helicopter or gyroplane, is widely used in national defence, military affairs, civilian etc.
Field, ABC rigid rotors are exactly that it takes using the identical but opposite direction of rotation close coupled type rigid rotor of two secondary rulers cun
The blade in common rotor that disappeared is used for being flexibly connected the horizontal hinge of propeller hub, vertical hinge, only retains pitch hinge.In flight course,
Close coupled type rigid rotor, which is only responsible for producing before lift need not produce, flies pulling force, and preceding winged pulling force is produced by auxiliary propulsion plant（X2 and
Card -92 is all afterbody ABC rigid rotors）, thus also without complicated auto-bank unit.When helicopter forward flight speed constantly increases
When, retreating blade is unloaded, and lift is gradually transferred on advancing blade, advancing blade is in high dynamic pressure flow field, can be very
Play a role well.After retreating blade unloading, pitch does not have to very greatly, therefore is not likely to produce air-flow separation stall.In addition, advancing blade
With the asymmetric turning torque of retreating blade lift, just cancelled out each other, kept by the opposite rotor in upper and lower two secondary direction of rotation
Lift balances.The pneumatic efficiency of so rotor greatly improves.Because rigid blades are not waved, upper and lower rotor can from very
Closely, without the danger of collision.The pitch for adding and subtracting to differential type upper and lower rotor is not only formed in horizontal direction with forming torsion difference
Steering, due also to the asymmetric lift of rigid rotor causes roll, further speed up turning process, thus use ABC rigidity
The helicopter of rotor has thundering mobility, substantially exceeds pure helicopter.Maximum excellent of ABC rigid rotors helicopter
Point is can be very convenient with VTOL, and still, compared with fixed wing aircraft, space rate is mutually far short of what is expected, and it is straight what obtains raising
Linear velocity is always the direction that people make great efforts, such as：Using double-deck ABC rigid rotors, including U.S.'s X-2 helicopters etc..It is existing
There are the following problems for technology：1st, speed is slow, and stability is poor, unstable；2nd, security is poor, and rotor wing tip is easily fought；3rd, energy
Consumption is big, noise is big；4th, rotor wing tip directly and air contact, easily produces drag due to shock wave.
Utility model content
The utility model purpose is to provide a kind of rotor wing tip fusion lift flying barrel device, and stability is high, has a smooth flight；Carry
High security, rotor wing tip will not fight, and energy consumption is low, reduces noise, and rotor wing tip is not direct and air contact, reduction produce sharp
The possibility of wave resistance, make helicopter or gyroplane with ABC rigid rotors, retain the advantages of helicopter be'ss original premise
Under, rectilinear flight speed is improved, solves above mentioned problem existing for background technology.
The technical solution of the utility model is：
A kind of rotor wing tip merges lift flying barrel device, comprising ABC rigid rotors and flying barrel, ABC rigid rotors it is cylindrical
Week is provided with flying barrel, and the flying barrel is annulus, and its cross sectional shape is similar with Airfoil Sections shape, the rotor wing tip of ABC rigid rotors
It is hinged between flying barrel inner side by hinge, hinge is fixed on flying barrel, and hinge insertion rotor wing tip, rotor wing tip can surround hinge
Axle swings.
The displacement hinge of the hinge and ABC rigid rotors is concentric shafts, and ABC rigid rotors can freely become as needed
Away from.The displacement hinge of ABC rigid rotors is known features.
The flying barrel cross sectional shape, with magic power flying barrel on the market（aerobie）Or lift flying barrel cross sectional shape phase
Together.The flying barrel cross sectional shape is that bottom is linear, and top is circular arc, and the low middle part in both ends is high.
The inner ring side of the flying barrel is provided with groove, and hinge is fixed in groove, in rotor wing tip insertion groove, in groove
Hinge inserts rotor wing tip, and rotor wing tip can swing around hinge.
The inner ring side of the flying barrel is provided with boss, and hinge is fixed on boss, the hinge insertion rotor wing tip on boss, rotation
Thriving point can swing around hinge.
Rotor wing tip swings around hinge, when being to adapt to ABC rigid rotor flights, rotor wing tip change angle
Degree.
Using the utility model, it is hinged between rotor wing tip and the flying barrel inner side of ABC rigid rotors by hinge, the rotor wing
Point swings around hinge, can manipulate the free displacement of ABC rigid rotors so that helicopter can keep the characteristics of original and property
Can, substantially increase rectilinear flight speed.In flight course, the air-flow of flying barrel periphery is to flying barrel center flow, helicopter
Add upward lift.
The beneficial effects of the utility model are：Stability is high, has a smooth flight（Gyroscopic effect）；Improve security, the rotor wing
Point will not fight, and energy consumption is low, reduces noise, and rotor wing tip is not direct and air contact, reduction produce the possibility of drag due to shock wave,
Make the helicopter or gyroplane with ABC rigid rotors, under the premise of the advantages of helicopter is original is retained, improve rectilinear flight speed
Degree.
