Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
Embodiment 1:
As it is shown in figure 1, the air force flotation gear of the present embodiment includes that rotating disk 1, price fixing 2, actuating unit are (in figure
Do not show) and vacuum generating device, rotating disk 1 and price fixing 2 are disposed as circle, and the upper surface of rotating disk 1 is shaped to smooth
Surface of revolution, to ensure the uniform force everywhere on rotating disk 1；Rotating disk 1 is arranged at above price fixing 2 and can be relative to fixed
Dish 2 rotates, and rotating disk 1, by a rotating shaft 4 and actuating unit drive connection, price fixing 2 has for leading to that rotating shaft 4 passes
Hole 21, is provided with bearing 40 and gas seal member 41 between through hole 21 and rotating shaft 4；It is formed between price fixing 2 and rotating disk 1
One gap 10, the width H in this gap 10 is 0mm～5mm.In the present embodiment, gap 10 is positioned at rotating disk 1
Between the edge of lower surface and price fixing 2 upper surface, between rotating disk 1 and the price fixing 2 inside gap 10, form an inner chamber 20,
And the height W of this inner chamber 20 is more than the width H in gap 10, as long as so guaranteeing on rotating disk 1 lower surface and price fixing 2
The machining accuracy of the edge of end face, it is possible to reach the dimensional requirement in gap, to reduce between rotating disk 1 and price fixing 2
Machining accuracy, avoids rotating disk 1 to rub with price fixing 2 phase in rotation process simultaneously；The vacuum generating device bag of the present embodiment
Including aspirating hole 31 and vacuum pump (not shown), aspirating hole 31 can be one, it is also possible to for multiple, aspirating hole 31
Being opened on price fixing 2 and be connected with inner chamber 20, the end of bleeding of vacuum pump connects aspirating hole 31, during use, utilizes true
Air in inner chamber 20 is extracted out by empty pump, is allowed to be formed as a low pressure chamber, is conducive to increasing the lift of device.
The mechanism of the present embodiment is as follows: according to aerodynamic principle, and air velocity more high pressure is the lowest, otherwise flow velocity is more
Low-pressure is the highest, when air flows through body surface, will produce and be perpendicular to airflow direction and the liter away from body surface
Power, its mathematic(al) representation is:
P=ρ0ν2S/2
Wherein,
P is the lift vector that body surface is perpendicular to airflow direction；
ρ0Density (kg/m for air3)；
ν is the speed (m/s) of object of which movement；
S is the active area (m of object and air-flow2)；
When the object of a circle rotates in atmosphere, suffered by its circular surface, the lift of air is represented by:
P=ρ0·f(ν,S)/2
Wherein, speed ν, area S are the functions of variable r, it may be assumed that ν=2 π nr, S=2 π r △ r, △ r is integration
Variable, obtains through integration:
P=ρ0·π3·n2·r4
Wherein,
N is the speed (revolutions per second) that object rotates；
R is the radius (m) of object；
Under normal circumstances, circular object rotates due to tow sides area equation in atmosphere, and angular velocity is equal, and air is close
Spend equal, so the lift being subject to is equal in magnitude, in opposite direction, and showing as lift is 0 (or the least)；If it is circular
Object tow sides atmospheric density is unequal, then the power suffered by two sides is the most unequal.If the air in circular object front
Density is ρ ', and the atmospheric density of reverse side is ρ ", the aerodynamic force suffered by circular object front is P ', then:
P '=ρ ' π3·n2·r4
Aerodynamic force suffered by circular object reverse side is P ", then:
P "=ρ " π3·n2·r4
Obviously, PMake a concerted effort=P '-P ' '=ρ ' π3·n2·r4-ρ”·π3·n2·r4
=(ρ '-ρ ") π3·n2·r4
According to above-mentioned formula, the flotation gear of the present embodiment is carried out force analysis as follows:
As it is shown in figure 1, at upper and lower surface and the upper and lower surface of price fixing 2 of rotating disk 1 all by pressure that air is vertical.Dress
Each side put also can be because these power are the most equal in magnitude, in opposite direction by the pressure of all directions of air,
So the pressure of each side of device is not considered.Assuming that surrounding air density is ρ0Time pressure be p0, then act on and turn
Pressure P above dish 11The pressure p produced equal to ambient pressure0The difference of the lift of S and rotating disk 1, it may be assumed that
P1=p0S-ρ0·π3·n2·r4, direction is downward
Assuming that the atmospheric density of inner chamber is ρ1Time pressure be p1, then the pressure P below rotating disk 1 is acted on2Equal in inner chamber
Air pressure p1S and rotating disk 1 rotate the difference of the downward lift produced, it may be assumed that
P2=p1S–ρ1·π3·n2·r4, direction is upwards
Owing to price fixing does not rotates, so acting on the pressure P above price fixing 23Equal to inner chamber is sealed into ρ1Air produce
Raw pressure p1S, it may be assumed that
P3=p1S, direction is downward
In like manner, owing to price fixing does not rotates, so acting on the pressure P below price fixing 24The pressure produced equal to ambient pressure
Power p0S is i.e.:
P4=p0S, direction is upwards
Then act on external force sum P on flotation gearCloseEqual to P1、P2、P3、P4Vector, it may be assumed that
PClose=-P1+P2-P3+P4=(ρ0–ρ1)π3·n2·r4, direction is upwards
It is not difficult to find out from above formula, when radius r and rotating speed n mono-timing of rotating disk 1, if atmospheric density ρ in inner chamber1
Atmospheric density ρ less than environment0, this device will produce lift upwards, and ρ1The least lift is the biggest, therefore, and profit
With the vacuum generating device in the present embodiment, the air in inner chamber is extracted out, make inner chamber be formed as the low pressure being close to vacuum
Chamber, can make the flotation gear of the present embodiment obtain a sufficiently large lift upwards, so that it floats in air.
It should be noted that ρ1Can not be less than 0, the ρ that the diameter 2r and rotating speed n of rotating disk 1 is also affected by1Limit,
Can not be infinitely great, the linear velocity of rotating disk 1 outer rim can be controlled in about velocity of sound.
Embodiment 2:
According to embodiment 1 acts on the P on flotation gearCloseFormula understands, the gap between price fixing 2 and rotating disk 1
10 width H level off to 0 time, ρ1It is 0, is now in a kind of perfect condition, i.e. without vacuum generating device, can make
Flotation gear obtains a lift upwards, but this kind of situation cannot realize, therefore, and can only be between price fixing 2 and rotating disk 1
Gap 10 do little as far as possible, and actual when manufacturing, the least production difficulty in gap 10 between price fixing 2 and rotating disk 1 is the highest,
And easily there is friction between closely located price fixing 2 and rotating disk 1, cause material serious wear, increase production cost；?
In real work, along with the rotation of rotating disk 1, at gap 10, rotating disk 1 can rub with price fixing 2 unavoidably, and
Increase gap 10 width.For the size of the most on-demand regulation gap 10 width H, as shown in Figure 2,3, price fixing 2
Outer peripheral face on be arranged with an annulus part 5, annulus part 5 is connected with the dismounting of price fixing 2 phase, the upper end of this annulus part 5 with turn
Forming gap 10 between dish 1, concrete, the top of annulus part 5 is inwardly convexly equipped with several connecting portions 51 and each company
Connect and in portion 51, be respectively provided with an installing hole 511, corresponding, price fixing 2 has a screwed hole 25, a screw rod 50 wears
In above-mentioned screwed hole 25 with in installing hole 511, during use, screw rod 50 is rotated up, drive on annulus part 5
Move, thus regulate the width H in the gap 10 between rotating disk 1 and price fixing 2.In order to prevent air at annulus part 5 with fixed
Between dish 2 periphery flow, be additionally provided with between the outer peripheral face of price fixing 2 with the inner peripheral surface of annulus part 5 at least together with sealing ring
6, the present embodiment is provided with 2 roads.
Embodiment 3:
The present embodiment is with the difference of embodiment 1: as shown in Figure 4,5, and the present embodiment is near in the upper surface of price fixing 2
Edge has the groove 23 of a circumference, is provided with at least one passage being connected with ambient atmosphere bottom this groove 23
24, what a ring-shaped article 7 can move up and down is inserted in above-mentioned groove 23, shape between upper end and the rotating disk 1 of ring-shaped article 7
Becoming gap 10, the ring-shaped article 7 in this enforcement can be an overall endless member, it is also possible to be that segmentation constitutes ring-type knot
Multiple parts of structure, during use, can first adjust ring-shaped article 7, make the width in gap 10 between this ring-shaped article 7 to rotating disk 1
Degree H is a size the least, when in inner chamber 20, atmospheric density is less than time extraneous, and air first passes through gap 10 and produces one
Fixed flow velocity, thus produce suction upwards in the upper plane of ring-shaped article 7, make gap 10 become less, but when ring-type
When gap 10 between the upper plane of part 7 and rotating disk 1 is the least, the air velocity flowing through gap 10 will decline, ring-shaped article
7 suction upwards decline the most therewith, and ring-shaped article 7, under the effect of self gravitation, moves down, and so can make gap
10 be maintained at one suitably in the range of, i.e. avoid strong friction, the least gap 10 can be kept again, so that interior
There is a stable low pressure in chamber.
Embodiment 4:
The present embodiment is with the difference of embodiment 1: as shown in Figure 6,7, and the present embodiment is on the outer peripheral face of price fixing 2
Being arranged with an annulus part 5, annulus part 5 is connected with the dismounting of price fixing 2 phase, concrete, the inside projection in top of annulus part 5
Have on several connecting portions 51 and each connecting portion 51 and be respectively provided with an installing hole 511, corresponding, price fixing 2 has
One screwed hole 25, a screw rod 50 is arranged in above-mentioned screwed hole 25 and installing hole 511；Meanwhile, the present embodiment is at annulus
Have the groove 52 of a circumference at the upper surface proximal edge of part 5, be provided with at least one bottom this groove 52 big with the external world
The passage 53 of gas phase connection, what a ring-shaped article 8 can move up and down is inserted in above-mentioned groove 52；Employing above two is tied
Structure cooperates to realize the large and small regulation of the width H to gap 10, and range of accommodation is more accurate.
Embodiment 5:
The present embodiment is with the difference of embodiment 2: as shown in Figure 8,9, if the vacuum generating device of the present embodiment is
Dry is opened on the outer peripheral face of rotating disk 1 and towards the duct 12 at rotating disk 1 center, the end in this duct 12 downwardly extends
It is connected with inner chamber 20, further, it is preferred that the end in duct 12 is near the center of rotating disk 1, the hole in the present embodiment
Road 12 is along the circumferentially-spaced layout of rotating disk 1, and when rotating disk 1 rotates, the linear velocity on periphery is than the line of immediate vicinity
Speed is big, and therefore, the air pressure at 12 mouthfuls of the duct on periphery is less than the air pressure at 12 mouthfuls of immediate vicinity duct, inner chamber
The air of 20 will flow outwardly by passing hole channel 12, so that inner chamber 20 produces low pressure, the flotation gear of this structure can
To be not required to be further provided with vaccum-pumping equipment, thus simplify the auxiliary equipment of this device, expand the practicality of this device.
Further illustrating, in the ideal situation, i.e. the gap 10 width H between rotating disk 1 and price fixing 2 is 0
Time, lift produced by the flotation gear of the present invention is:
PRise=ρ0·π3·n2·r4
According to the viscosity theory of newton, the resistance that rotating disk 1 upper surface produces is:
PResistance=4 π2·n·ρ0·r3·C/3
Wherein, C is the coefficient of kinetic viscosity (m/s) of air；
Owing to rotating disk 1 does not has front face area when rotated, the most just there is no frontal resistance, so when rotating disk 1 rotates
Resistance mostlys come from the viscosity resistance of air, and the lift-drag ratio of rotating disk 1 is:
PRise/PResistance=(ρ0·π3·n2)/(4/3π2·n·ρ0·r3C)=3 π n r/ (4C)
Assuming that r is 1m, n is 50 revolutions per seconds, it will therefore be readily appreciated that the lift-drag ratio of this device is far longer than conventional aircraft；If
Disregarding drive system power attenuation bottom rotating disk, the power attenuation of disk upper surface is W, then W is equal to PResistanceIt is multiplied by
Linear velocity ν, PResistanceIt is all the function of variable radius r with ν, it may be assumed that
W=C ρ0·f(ν2,S)
=C ρ0·∫(2πnr)2·2πrdr
=2 π3·n2·r4·ρ0·C
Then rate of climb V=W/P of this deviceRise=(2 π3·n2·r4·ρ0·C)/(ρ0·π3·n2·r4)=2C
Obviously, this is a numerical value the least, it may be said that bright, and this device can use the least driving force and the least driving
Power makes rotating disk obtain the biggest lift, does not drops so that this device floats in air, but simultaneously because drives merit
Rate is the least, and the rate of climb of this device is very slow, therefore, using this device as during one flight, lifting, push-and-pull etc.
Auxiliary device use more particularly suitable.
Although the preferred embodiments of the present invention described in detail above, it is to be clearly understood that for this area
For technical staff, the present invention can have various modifications and variations, and in the various embodiments described above, the diameter of price fixing can do
Ratio rotating disk big, now rotating shaft and the actuating unit of rotating disk can be supported on a support, and it is fixed that the leg of support is fixed on again
