Little spring in wing sweeping mechanism is compressed, and joint is become the location guide one of sweepback mechanism to the adaptive wing
Side is moved, so as to control wing setting to increase to 20 ° by 10 °.
When aircraft flying height >=4000 meter and≤ten thousand metres：Adjustment support set is moved at the 1/2 of the support set stroke,
So that little spring adjusts taper sleeve telescopic, it is bonded with control section small spring ring with adjustment tapered sleeve so that the deformable number of turns of little spring
Reduce.Big spring adjusts tapered sleeve and progressively expanded under natural resiliency effect so that big spring is bonded with big spring adjustment tapered sleeve
The number of turns reduces, so as to increase the practical distortion number of turns of big spring.Mach number increases by 0.4, when little spring is by compression time control
The angle of sweep change slope increase of system, when flying speed reaches 0.7, little spring will be fully compressed, corresponding wing sweepback
Angle goes to 18 °.
When the flying height of aircraft is more than ten thousand metres：Adjustment support set is moved to the support set stroke to joint direction always

16 °~60 ° of angle.
The present invention, which is directed in existing variable-sweep wing structure design, needs the external energy such as hydraulic pressure unit and control to calculate
The units such as machine, complicated, the features such as weight is big, innovative design is carried out.Flown with being acted in flight course on wing
Row resistance rationally designs speed adaptive variable-swept wlng structure, makes flight resistance to change the drive energy of wing setting degree
The mechanism kinematic is controlled, and then controls sweepback angle, realizes the corresponding relation at flying speed and angle of sweep；Meanwhile can be according to winged
The different different stalls for manually selecting speed adaptive variable-swept wlng structure of row height, are realized under different flying heights, flight speed
Degree and the corresponding relation at angle of sweep.
The present invention realizes change as shown in Figure 1 according to the change requirement of sweepback angle and flying speed and flying height
Law, it have received preferable effect.Wherein：
1st, when flight Mach number is less than 0.4, angle of sweep maintains initial angle；
2nd, flight Mach number is more than 0.4：And：
I when flying height be less than 4000 meters when, angle of sweep with flying speed changing rule such as Fig. 1 middle polylines 33 and broken line
Shown in 34：
Flight Mach number is from during 0.4 increases to 0.6, and as shown in Fig. 1 middle polylines section 33, angle of sweep is by initial angle
It is linearly increasing to 20 °；
Flight Mach number is from during 0.6 continues to increase to 0.9, and as shown in Fig. 1 middle polylines section 34, angle of sweep is from 20 °
Increase linearly to 60 °.
II when flying height >=4000 meter and during≤ten thousand metres, and angle of sweep in the changing rule such as Fig. 1 of flying speed with rolling over
Shown in line 35 and broken line 36：
Flight Mach number is from during 0.4 increases to 0.7, and angle of sweep increases linearly to 18 ° from 10 °, such as Fig. 1 middle polylines
Shown in section 35；
Flight Mach number is from during 0.7 continues to increase to 0.9, and angle of sweep increases linearly to 60 ° from 18 °, in Fig. 1
Shown in broken line 36.
III when flying height is more than ten thousand metres, angle of sweep with flying speed changing rule such as Fig. 1 middle polylines 37 and folding
Shown in line 38：
Flight Mach number is from during 0.4 increases to 0.8, and angle of sweep increases linearly to 16 ° from 10 °, such as Fig. 1 middle polylines
Shown in 37；
Flight Mach number is from during 0.6 continues to increase to 0.9, and angle of sweep increases linearly to 60 ° from 16 °, in Fig. 1
Shown in broken line 38.
Require that can be seen that the change between wing setting degree and flying speed is typical piecewise function from control,
Two sections of different linear relationships are presented in whole excursion.Meanwhile the middle turning point position of the linear relationship is high with flight
Degree change and change, the characteristics of generally showing broken line race.
1) between flying speed and angle of sweep broken line rule realization.
The present invention fixes by the joint of location guide side by bearing and with fuselage, and the aerodynamic drag load of wing passes through
Joint, moveable combination of guide rod are delivered to little spring adjustment swivel nut, compression little spring deformation；After little spring is gradually compressed to the limit,
When aerodynamic drag continues increase, aerodynamic loading will be applied on big spring by the little spring of compression, spring base, makes big spring pressure
Contracting, joint and moveable combination of guide rod continue to retract.Because big little spring has different rigidity so that the retraction of aerodynamic loading and joint
The corresponding relation of two sections of Different Slopes is realized between stroke.
2) when flying height changes, the realization of the rule (broken line race) between flying speed and angle of sweep
In Fig. 1, when flying height is higher, the position of the middle turning point of broken line more moves up, that is, requires sweepback
10 ° of angle~flying speed corresponding to 12 ° is higher, and 12 ° of angle of sweep~flying speed scope corresponding to 60 ° is smaller.If driving
One control crank of setting in cabin is sailed, drives the travelling gear in the present invention to rotate by transmission mechanism, drives top cover to rotate simultaneously
It is axially moved, is axially moved by thrust bearing support set, so as to changes big spring adjustment tapered sleeve and little spring adjustment tapered sleeve
Taper, the control size camber of spring number of turns changes simultaneously, and then causes two sections of curves of flying speed and sweepback angle
Slope changes.When flying height raises, control travelling gear to rotate by control crank, drive top cover to rotate and to joint side
To motion, support set is hauled by pressure ring and does equidirectional motion, force little spring adjust taper sleeve telescopic, control section small spring ring with
Fixed tapered sleeve fitting so that the deformable number of turns of little spring reduces；Simultaneously big spring adjustment tapered sleeve natural resiliency effect under progressively
Expansion so that big spring reduces with the number of turns that is bonded of big spring adjustment tapered sleeve, so as to increase the practical distortion number of turns of big spring, this
Sample will make the increase of little spring control section rigidity, and big spring control section rigidity reduces, as long as according to flight altitude control support set not
Same axial location, you can ensure that two sections of control slopes change with flying height.So it is achieved that 10 °~12 ° of angle of sweep is right
The flying speed answered increases, and the rule that 12 ° of angle of sweep~flying speed scope corresponding to 60 ° diminishes.
It can thus be seen that in the implementation of the invention, the energy of driving wing setting degree change hinders from flight
Power, the hydraulic energy or electric energy that not outer portion provides.Meanwhile the control process of whole wing setting degree change is entirely by pneumatic
Resistance and size amount of spring compression change in the speed adaptive wing sweeping mechanism of manual height gear are self balancing, do not have
There are the transmission and control of electric signal, eliminate control computer and relevant hardware devices.
As can be seen here, the maximum difference of the invention with current prior art is that the drive energy of the sweepback angle of wing comes
From the flight resistance acted in flight course on wing, it is not necessary to which extra power provides driving power.It is of the invention and existing
The difference for having technology also resides in the control of wing setting degree without the control using electric signal, completely by the change of flight resistance
Change, the tune of wing setting degree is automatically realized by the speed adaptive wing sweeping mechanism of the manual height gear designed
It is whole.
Compared with prior art, the speed adaptive wing sweeping mechanism of manual height gear at least 2 advantages：
One is due to reduce the driving elements such as control computer, hydraulic system so that whole to become sweepback mechanism light；Second, control
The realization of rule is realized by the mechanical device of longer life completely, high compared to electronic equipment, reliability.
