Embodiment
Shown in Fig. 1～4, board-like propellant management device hydraulic accumulator comprises following constituent element: hydraulic accumulator inner cone 1, hydraulic accumulator outer cone 4, hydraulic accumulator base 5, air pipe 3, two air pipe fixed blocks 2, two hydraulic accumulator net sheets prop up pressing plate 6, hydraulic accumulator net sheet 7.Hydraulic accumulator inner cone 1 and 4 electron beam weldings of hydraulic accumulator outer cone; Hydraulic accumulator outer cone 4 and 5 electron beam weldings of hydraulic accumulator base.
Hydraulic accumulator has adopted inside and outside two complete cone structures; It is the cone structure of said hydraulic accumulator inner cone 1 and said hydraulic accumulator outer cone 4 compositions; Utilize surface tension to hold and stay sufficient propellant agent through the angle zone between the zone of the angle between said hydraulic accumulator inner cone and the said hydraulic accumulator outer cone and said hydraulic accumulator outer cone 4 and the said tank inner walls face 8; Adopted said air pipe that gas in the said hydraulic accumulator is discharged, adopted the chief component of the said hydraulic accumulator base of cylinder type as the bubble trap.
Reach best in order to make said hydraulic accumulator hold the liquid effect, optimal design the cone angle of said hydraulic accumulator outer cone, cone angle is 45 °.
Carry out position required propelling dosage of thruster when protecting according to satellite, optimal design the height and the volume of said hydraulic accumulator outer cone, confirmed the maximum liquid storage content of said hydraulic accumulator.The lower pyramid mouth internal diameter of said hydraulic accumulator outer cone and tank internal diameter ratio are 1: 10, and height is 1: 1.5 with the lower pyramid mouth internal diameter ratio.
Under microgravity environment, the angle zone between said hydraulic accumulator inner cone and said hydraulic accumulator outer cone will be held and stayed a part of propellant agent, and final surface tension and microgravity reach balance.For making this regional liquid storage content many as far as possible, optimal design the angle between said hydraulic accumulator inner cone and the said hydraulic accumulator outer cone, said angle is 40 °.
Consider the work requirements of said hydraulic accumulator under nominal situation and reverse microgravity operating mode, optimal design the entry depth H of said hydraulic accumulator inner cone, said entry depth is the half the of the outer cone height of said hydraulic accumulator.
Optimal design the transition segmental arc of said hydraulic accumulator inner cone, the segmental arc radius is 0.8 times of entry depth H.If the segmental arc radius is excessive, surface tension is difficult to support propellant agent and is distributed to said hydraulic accumulator inner cone ingress, influences the liquid storage content of said hydraulic accumulator; If the segmental arc radius is too small, the propellant agent deflection is held and is stayed near this segmental arc, said trap is exposed in the gas, thereby influences effective liquid storage content of said hydraulic accumulator.
In order in filling process, gas in the said hydraulic accumulator to be discharged; Specialized designs novel said air pipe; As shown in Figure 3; Air pipe 3 is connected with 1 resistance spot welding of hydraulic accumulator inner cone through two air pipe fixed blocks 2 and is fixing, and an end of air pipe 3 is put in the regional top of angle between hydraulic accumulator inner cone and the hydraulic accumulator outer cone as far as possible, and the while is made a call to an aperture at this end of air pipe 3; Guaranteed the high extrusion efficiency of said board-like PMD so that carry out exhaust to greatest extent, also improved it and born the ability of microgravity level.
As shown in Figure 2, designed auricle with holes in said hydraulic accumulator base 5 outer cylinder, said hydraulic accumulator base 5 supports whole said hydraulic accumulator.Interior cylinder at said hydraulic accumulator base has designed a step, is convenient to said hydraulic accumulator net sheet and props up installing and fixing of pressing plate 6 and hydraulic accumulator net sheet 7, has just formed a liquid-accumulating trough in said hydraulic accumulator bottom.Said hydraulic accumulator net sheet 7 can be tackled bubble effectively, has improved the filling speed of said board-like propellant management device and is prone to dry up, and helps the function that realizes that said board-like propellant management device repeats to annotate.The use of said hydraulic accumulator net sheet has solved the inconsistent problem of welding consumables.
As shown in Figure 2, hydraulic accumulator net sheet 7 is clipped in two hydraulic accumulator net sheets and props up between the pressing plate 6, with its electron beam welding, and will guarantee that two hydraulic accumulator net sheets prop up the hole complete matching of pressing plate 6.The overall structure electron beam welding that hydraulic accumulator net sheet 7 and two hydraulic accumulator net sheets prop up after pressing plate 6 welding is received on the interior cylinder step of hydraulic accumulator base 5.
At the tank end of lifetime, under microgravity environment, liquid holds basically stays zone and hydraulic accumulator zone between guide plate 10 and the tank inner walls face 8, as shown in Figure 7.Along with the basic emptying of liquid in the hydraulic accumulator, the liquid that is distributed in tank shell wall side 8 is transferred to board-like PMD bottom along guide plate 10 under surface tension effects, gives hydraulic accumulator 9 topping ups through trap up and down.Give the hydraulic accumulator topping up through guide plate when treating in the hydraulic accumulator the basic once more emptying of liquid, discharge opeing so repeatedly, topping up be the liquid emptying in tank.Hydraulic accumulator net sheet 7 can stop gas to get into the tank liquid outlet, realizes the not purpose of gas enclosure discharge opeing.
This hydraulic accumulator has extensive applicability; Hold in not only can the various microgravity environments under nominal situation and stay propellant agent; And under the extreme case of various improper operating modes, also can hold and stay sufficient propellant agent; As when Z is big to (axially) angular velocity of rotation, when backward acceleration is big (satellite along X, the rotation of Y axle time also can occur), shown in Fig. 8～11.
