Description
Technical field
The present invention relates to a kind of propellant management device, be specially adapted to Propellant Management under space microgravity environment.
Background technique
Surface tension propellant tank is high reliability under weightlessness and long lifetime feature with it, is widely used on the various astrovehicles such as satellite, airship, space station, carrier rocket.The core technology of surface tension propellant tank is its inner propellant management device (being called for short PMD).Plate-type propellant management apparatus belongs to the advanced management apparatus reliably of a new generation.The target of guide plate design is to design one of reliability board-like PMD core component high, lightweight, simple in structure.
At present, the PMD of the surface tension propellant tank using on China's satellite is net formula, adopting screen cloth is that capillary element is collected propellant agent, and the liquid mouth that propellant agent is transported to surface tension propellant tank by pipeline holds, and not yet uses at home guide plate transfer management propellant agent.But the guide plate that most of board-like PMD are used in the world belongs to and is arranged vertically type guide plate, and such guide plate exists some shortcomings: structural strength is low, and processing technology and installation difficulty are large, be difficult for being connected with hydraulic accumulator.
Summary of the invention
Technical problem to be solved by this invention is: overcome the deficiencies in the prior art, provide that a kind of reliability is high, quality is light, the guide plate of the plate-type propellant management apparatus of favorable expandability.
A guide plate for plate-type propellant management apparatus, described guide plate is near described tank inner walls face layout and extend to liquid outlet always, and described guide plate is parallel with described tank inner walls face; In microgravity environment, liquid is under surface tension effects, can be along the crack transmission forming between described guide plate and described tank inner walls face, in described guide plate both sides, form symmetrical liquid band, described guide plate is banded plank frame, the plate of described guide plate wide with ratio tank internal diameter be 2: 35.
Described guide plate is carried out to flanging processing, make described guide plate form a groove structure; Flanging angle is 45 °, and the wide ratio of flanging height and plate is 1: 10.
At the two ends up and down of guide plate, six mounting holes are set respectively.
The present invention compared with prior art, has as follows a little:
(1) guide plate of the present invention has mainly adopted brand-new plank frame form, and structural strength is large, and reliability is high, and strong adaptability is easily connected with hydraulic accumulator;
(2) deflector structure of the present invention is simple, and quality is light;
(3) guide plate of the present invention can carry out adaptability revision according to plate-type propellant management apparatus physical dimension, and its volume extensibility is good;
(4) guide plate of the present invention can effectively be restrained rocking of liquid, improves the precision of the attitude control of satellite.

Embodiment
As shown in Figure 1, guide plate 1 is selected banded plank frame form, and with described tank inner walls face 2 parallel placements, i.e. parallel type guide plate.In microgravity environment, liquid, under surface tension effects, can, along the crack transmission forming between guide plate and tank inner walls face, form symmetrical liquid band in guide plate both sides.Guide plate can guarantee sufficient transmission speed when stable state, when unsteady state, also can ensure enough transmission speeds, and cutout and liquid band gas enclosure can not occur, and recovers at short notice stable.Described guide plate can effectively be realized gas-liquid separation under microgravity environment, water conservancy diversion transmission performance with hold fluidity can be good.
Clearance distance size between described guide plate 1 and described tank inner walls face 2 is the described guide plate transmission of impact and holds one of key factor of fluidity energy.If the too small described guide plate transmittability of clearance distance is not enough; If clearance distance is excessive, described guide plate hold liquid scarce capacity, and then also can cause described guide plate transmittability not enough.By the clearance distance between guide plate described in optimization reasonable design and described tank inner walls face.Choosing of this distance is relevant with tank internal diameter, and this distance is as follows with the ratio Choice of internal diameter: when internal diameter φ is greater than 800mm, ratio is 1: 100; When internal diameter φ is not more than 800mm, ratio is 1: 50.
The plate of described guide plate is wide be the described guide plate transmission of impact and hold fluidity can one of key factor.If plate is wide too small, will the liquid storage content of described guide plate be reduced, and then cause the transmittability of described guide plate not enough; If plate is wide excessive, will increase the weight of board-like full management PMD.Therefore it is roomy little to have passed through to optimize reasonable design the plate of described guide plate.Choosing that plate is wide is relevant with tank internal diameter.Plate wide with ratio internal diameter be 2: 35.
If described guide plate is a slate configuration, its structural strength is more weak.Consider structural strength requirement, described guide plate has been carried out to flanging optimization process, strengthened widely the structural strength of described guide plate.The angle of flanging 4 is 45 °, and the wide ratio of flanging height and plate is 1: 10.Described guide plate is carried out after flanging processing, described guide plate just forms a groove structure, this groove structure becomes another paths of described guide plate transmission propellant agent, and described guide plate can hold and stay more propellants, and its propellant agent transmittability is further improved.
Six uniform mounting holes 3 at the two ends of guide plate, have all been beaten, so that the installation of guide plate is fixed.
At tank beginning of lifetime, under microgravity environment, liquid is not in sinking to the bottom state in tank, and guide plate is immersed in liquid, as shown in Figure 2.Along with liquid is constantly consumed, hydraulic accumulator 6 inner cones expose liquid level, and liquid is near tank inner walls surface distributed, as shown in Figure 3, liquid under surface tension effects along guide plate to hydraulic accumulator 6 topping ups.
At tank end of lifetime, under microgravity environment, liquid holds substantially stays region and hydraulic accumulator 6 regions between guide plate and tank shell wall side, as shown in Figure 4.Along with the interior liquid of hydraulic accumulator 6 is discharged substantially, the liquid that is distributed in tank shell wall side is transferred to board-like PMD bottom to hydraulic accumulator topping up along guide plate under surface tension effects.When the interior liquid of hydraulic accumulator 6 is discharged again by guide plate to hydraulic accumulator 6 topping ups, so repeatedly liquid constantly by guide plate to hydraulic accumulator 6 topping ups.
