Description
Technical field
The present invention relates to aircaft configuration technical field, especially a kind of wing flap control mechanism of light-duty sport plane.
Background technique
Most of light-duty sport plane of the prior art is wing flap and aileron by push and pull system using hydraulic actuating mechanism
Manipulation solution is provided.Executing agency on many commercial aircrafts is made of a screw rod, and screw rod drives nut along screw rod
Length direction moves up and down, to drive bracket of one or more locks on control surface component.With multiple wing flaps
On aircraft, each wing flap by its own screw mechanism drive, each screw rod be it is shaft-driven by one, this axis passes through
One bevel gear or worm screw gearbox are connected to screw rod along the length of wing, and this construction machine is complicated, and weight is big, manufacture and
Maintenance cost is high.In addition, it does not allow each wingflap mechanism individually activity and automation control.Traditional light-duty movement is caused to fly
The control precision of the component controls mechanism of machine is low, low to the Operational Figure Of Merit of aircraft；Make pilot in flight operation to flight
The control difficulty of device increases；And existing design leads to mechanism wing structure outstanding, needs to add radome fairing, causes to increase
Fluid resistance.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide, a kind of structure is simple, reduces resistance
Power, each wing flap of permission individually control and are completely enclosed within the wing flap control mechanism of the light-duty sport plane in flap configurations.
The technical scheme adopted by the invention is that: a kind of wing flap control mechanism of light-duty sport plane includes wing flap and wing flap
Driving mechanism, the wing flap driving mechanism are set in the wing flap and for enabling each wing flap to be independently steered exhibition
It opens.
Further, the wing flap driving mechanism includes conjunction with motor group, flap kinematics mechanism and drive shaft；The joint
Motor is mounted among the wing flap and arranged in parallel with the leading edge of the wing flap, and the conjunction with motor group passes through the drive shaft
The flap kinematics mechanism is driven, the drive shaft extends to the side of the wing flap and in the driving shaft end equipped with tooth
Wheel.
Further, the flap kinematics mechanism includes rack gear, rocker arm, the first set of rollers on the rocker arm and
Two set of rollers and the first track engaged therewith and the second track；The rack gear is fixed on wing, and the gear is engaged on
On the rack gear and for providing a variable wing flap movement routine.
Further, the wing flap driving mechanism is completely contained in the wing flap.
Further, the conjunction with motor group includes first motor interconnected and the second motor.
The beneficial effect of the present invention compared with the prior art is: due to a kind of flap of light-duty sport plane of the present invention
Wing control mechanism includes wing flap and wing flap driving mechanism, and the wing flap driving mechanism is set in the wing flap and for making each institute
Expansion can be independently steered by stating wing flap, by for two axis providing power there are two motor in the assembly of wing flap driving mechanism,
There is a pinion gear on the outside of each axis, pinion gear drives a band, and there are four the rocker arms of roller, and roller is in lock in rib structure
On track on travel.Two rather than a motor are for allowing flap kinematics, to prevent the failure of any one motor.Often
Platform motor can provide enough power to operate wingflap mechanism.During wing flap stretches out, the design of trajectory path is to make the flap
The wing is protruding along the first half straight line that track moves, and then moves downward, and increases flap angle.This orbital path design
Wing flap is allowed to extend and stop before starting to move downward.In this position, wing flap can be the case where not increasing induced drag
Lower increase wing chord and aerodynamic lift, effectively provide that a kind of structure is simple, reduce resistance, each wing flap is allowed individually control and complete
It is enclosed in the wing flap control mechanism of the light-duty sport plane in flap configurations.
Detailed description of the invention
Fig. 1 is overall structure of the present invention；
Fig. 2 is wing flap driving mechanism of the present invention side structural schematic diagram.
Specific embodiment
Below in conjunction with the attached drawing in the present invention, the technical solution in the present invention is clearly and completely described.
As shown in Figure 1 and Figure 2, a kind of wing flap control mechanism of light-duty sport plane of the present invention includes wing flap and the flap
Wing driving mechanism, the wing flap driving mechanism are set in the wing flap and for enabling each wing flap to be independently steered
Expansion.
Further, the wing flap driving mechanism includes conjunction with motor group 1, flap kinematics mechanism and drive shaft 2；It is described
It is among the wing flap and arranged in parallel with the leading edge of the wing flap to close motor group 1, the conjunction with motor group 1 passes through the drive
Moving axis 2 drives the flap kinematics mechanism, and the drive shaft 2 extends to the side of the wing flap and in 2 end of drive shaft
Equipped with gear 3.
Further, the flap kinematics mechanism includes rack gear 4, Rocker arm 5, the first set of rollers 6 on the Rocker arm 5
With the second set of rollers 7 and the first track 8 engaged therewith and the second track 9；The rack gear 4 is fixed on wing, the tooth
Wheel 3 is engaged on the rack gear 4 and for providing a variable wing flap movement routine.
Further, the wing flap driving mechanism is completely contained in the wing flap.
Further, the conjunction with motor group 1 includes first motor interconnected and the second motor.
By for two axis providing power there are two motor in the assembly of wing flap driving mechanism, have on the outside of each axis one small
Gear, pinion gear drive a band there are four the rocker arm of roller, and roller travels on locking the track in rib structure.Two and
It is not a motor is for allowing flap kinematics, to prevent the failure of any one motor.Every motor can provide enough
Power operates wingflap mechanism.During wing flap stretches out, the design of trajectory path is the first half for moving wing flap along track
Divide straight line protruding, then move downward, increases flap angle.This orbital path design allows wing flap starting fortune downwards
Extend before dynamic and stops.In this position, wing flap can increase wing chord and aerodynamic lift in the case where not increasing induced drag.
When motor group, which receives signal, to extend wing flap, drive shaft 2 starts to rotate, and band moving gear 3 moves on rack gear 4.Gear 3 with
Rocker arm 5 and wing flap move on rack gear 4 together.When Rocker arm 5 and mobile gear 3, two groups of set of rollers move on two groups of tracks；
The movement of two groups of track wing flaps is set to provide a stable path, compact design is completely enclosed within flap configurations, provides
One clean air force section, to reduce resistance, it is lighter than present design, make maintenance become easy with it is low at
This, design allows each wing flap individually to control, and under asymmetric loading conditions, this has very big advantage, such as military
On aircraft, when bomb is fallen from wing.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Belong to those skilled in the art in the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of, all answers
It is included within the scope of the present invention, therefore, protection scope of the present invention should be subject to the protection scope in claims.
