From the energy point of view analysis, aerostatics is in the decline process, and air intake apparatus constantly does work, and the gas transport of low-pressure state in high-pressure gasbag, is followed the decline process of aerostatics, and air intake apparatus is in the acting state always.And the potential energy in the dirigible decline process constantly reduces on the other hand, consumes in the fricting movement of decline process and air, but is not utilized.
The utility model content
The deficiency that the utility model exists to prior art just, the aerostatics that provides a kind of opening to facing the wind and descend.When descending, aerostatics is opened valve, is in the opening air inlet in right amount of state down with the wind, reduces the expenditure of energy of aerostatics in the decline process.
For addressing the above problem; The technical scheme that the utility model is taked is following: the aerostatics that a kind of opening facings the wind and descends; Comprise air bag; Said air bag below is provided with: the valve that the dynamic head that descending facings the wind forms is opened during greater than the inside and outside differential pressure of aerostatics, and the control setup that is used to drive valve open.
Said valve openings area S satisfies following formula:
Wherein: v is a descending speed, V
BallBe the aerostatics volume, T is a local temperature, and ρ is local density of air, and Δ P is the aerostatics inside and outside differential pressure, and k is a coefficient of correction.
Be provided with barrier film in the said air bag, barrier film is divided into air bag helium capsule that is positioned at the top and the air bag that is positioned at the below; Fill helium in the said helium capsule, fill air in the air bag.
Said air bag comprises helium capsule and air bag, and the helium capsule is arranged in the air bag; Fill helium in the said helium capsule, fill air in the air bag.
The beneficial effect of the utility model is: the aerostatics that the described opening of the utility model facing the wind to descend can actv. utilizes the potential energy of aerostatics; The potential energy of aerostatics is converted into ability in the aerostatics; Make the air bag of aerostatics obtain replenishing effectively, saved the needed energy in the aerostatics decline process.

The specific embodiment
To combine concrete embodiment that the content of the utility model is described below.
Be illustrated in figure 1 as the utility model embodiment one said aerostatics structural representation.The said aerostatics of present embodiment comprises air bag 1, valve 2 and control setup 3.Air bag 1 is the main carrier of aerostatics, and set inside has barrier film 5, and barrier film 5 is divided into helium capsule 6 and air bag 7 with air bag 1 internal cavities.Helium capsule 6 is positioned at the top of air bag 1.Helium capsule 6 inside are filled with a certain amount of helium 4, mainly provide buoyancy to swim in the air by aerostatics by helium 4.Air bag 7 inside are filled with air 8, and air 8 lets aerostatics keep the inside and outside differential pressure of air bag 1, guarantees the aerodynamic configuration of aerostatics.Valve 2 and control setup 3 are arranged on the below of air bag 7, valve 2 be arranged on air bag 7 under.Air bag 1, valve 2 and control setup 3, rational weight of three and buoyancy configuration make aerostatics be in a kind of state of equilibrium.
As shown in Figure 2, be the said valve 2 closed condition scheme drawings of present embodiment, Fig. 3 is its open mode scheme drawing.The state of nature of valve 2 is in closed condition.Control setup 3 comprises sensor, and this sensor is arranged on valve 2 places.When aerostatics aloft descended, whether the dynamic head that the sensor sensing at valve 2 places facing the wind to form was greater than the inside and outside differential pressure of aerostatics.When the dynamic head that facing the wind to form during greater than the inside and outside differential pressure of aerostatics, sensor is given control setup 3 feedback signals, is driven by control setup 3 and opens valve 2, and extraneous air gets into air bags 7 through valve 2.
As shown in Figure 4, view when descending for the said aerostatics of present embodiment.Among Fig. 4, aerostatics descends with speed v.In order to realize that aerostatics can the actv. air inlet when descending; The opening of aerostatics lower end valve 2 is in state down with the wind always when aerostatics descends; Under certain descending speed v guarantees; The dynamic head that forms down with the wind is greater than the inside and outside differential pressure of aerostatics, and extraneous air can effectively get into air bags 7 through valve 2, and then additional air bag 7 in-to-in air 8.
The air inlet situation of extraneous air when the aperture area S of valve 2 directly influences aerostatics decline.When area S was excessive, the transient state suction quantity was too much, and the aerostatics descending speed is too fast, influenced its decline balance; When area S was too small, the transient state suction quantity was very few, underused the potential variation of decline.The aperture area S of the described valve 2 of the utility model satisfies following formula:
Wherein: v is a descending speed, V
BallBe the aerostatics volume, T is a local temperature, and ρ is local density of air, and Δ P is the aerostatics inside and outside differential pressure, and k is a coefficient of correction.
The opening shape of valve 2 has certain influence to coefficient of correction k, and according to the practical experience formula, general coefficient of correction k span is 0.02 ~ 0.03.
As shown in Figure 5, be the utility model embodiment two said aerostatics structural representations.Embodiment two with embodiment one key distinction is: do not have barrier film 5 in the embodiment two described air bags 1, air bag 1 comprises helium capsule 6 and air bag 7, and helium capsule 6 is set directly in the air bag 7.
The utility model is in aerostatics, to fill helium as floating empty gas, likewise, fills other the little similar light gas of density ratio density of air, also can realize the function of the utility model, and this does not break away from the essence of the utility model.
