Description

Technology Field

[0002] Generally, various types of actuators are applied for aircraft attitude control, and among them, blowdown hydraulic power sources are frequently used considering space constraints and system complexity. The blowdown method includes a pressure vessel, a reservoir, and a pressure regulator; it is configured such that gas regulated to a constant pressure is supplied to the reservoir, through which the liquid (operating fluid) required to ensure actuator performance is discharged from the reservoir at a pressure and flow rate exceeding a certain level. For reference, the reservoir includes a piston, bellows, bladder, and rubber diaphragm to physically separate the gaseous and liquid sections.

[0003] Conventional pressurized liquid supply systems provide sufficient performance in systems using only a single storage container; however, when multiple containers are applied, uneven discharge causes unintended shifts in the center of gravity of the drive mechanism system, which in turn affects the entire system. Specifically, because the differential pressure required to discharge liquid differs depending on the separation structure of the gaseous and liquid sections within each container, a characteristic occurs where liquid is discharged sequentially starting from the container with the lowest differential pressure.

Specific details for implementing the invention

[0022] Hereinafter, preferred embodiments of the present invention are described with reference to the accompanying drawings to fully understand the present invention. Embodiments of the present invention may be modified in various forms, and the scope of the present invention should not be interpreted as being limited to the embodiments described in detail below. It should be noted that in each drawing, identical components may be illustrated with the same reference numerals. Detailed descriptions of known functions and components that are deemed to unnecessarily obscure the essence of the present invention are omitted.

[0023] Referring to FIGS. 1 and 2, the present invention is a balanced discharge system of a pressurized liquid supply device including a plurality of storage containers, wherein the pressurized liquid supply device (100) comprises a pressure vessel (101), a first shut-off valve (102), a pressure regulator (103), a first check valve (104) for preventing backflow of pressurized gas, a plurality of storage containers (105), a first differential pressure regulating orifice (106), a second differential pressure regulating orifice (107), a second check valve (108) for setting a minimum value of the test specimen supply pressure, a second shut-off valve (109), and a test specimen (110).

[0024] That is, the pressure vessel (101) is a vessel filled with a pressurizing agent to discharge liquid from a plurality of storage vessels (105) and supply a pressure and flow rate above a certain level to a test specimen (110), and is opened and closed through a first shut-off valve (102).

[0025] The pressurizing agent supplied from the pressure vessel (101) is regulated to a constant pressure using a pressure regulator (103), and after passing through the first check valve (104), flows into the gas portion of a plurality of storage vessels (105).

[0026] In order to supply liquid to the above test specimen (110), the second shut-off valve (109) must be opened, and accordingly, the liquid pressure of the plurality of storage containers (105) is formed as a pressure excluding the differential pressure generated when the internal piston, bellows, etc. move.

[0027] At this time, when manufacturing the pressurized liquid supply device (100), the internal differential pressure of the storage container (105) When ) occurs, the internal differential pressure deviation of the storage container (105) ( ) can be expressed as a mathematical formula as follows.

[0028]

[0029] Here, is the internal differential pressure reference value of the storage container (105), is the internal differential pressure deviation of the storage container (105).

[0030] Additionally, between the plurality of storage containers (105) and the second opening / closing valve (109), first and second differential pressure regulating orifices (106) (107) and a second check valve (108) are located, and the orifice differential pressure level of the first and second differential pressure regulating orifices (106) (107) is set by reflecting the internal differential pressure characteristics occurring in the gaseous and liquid parts of individual storage containers (105) so that liquid is discharged evenly from the plurality of storage containers (105).

[0031] The above second check valve (108) is the minimum supply pressure required by the test specimen (110) The cracking pressure is set so that the liquid supply is greater than )

[0032] The piping connecting the plurality of storage containers (105) to the test specimen (110) is configured to secure a sufficient inner diameter relative to the supply flow rate so that the effect of differential pressure reduction due to the flow rate does not occur.

[0033] The following describes the design method and operating principle of a balanced discharge system for a pressurized liquid supply device according to an embodiment of the present invention.

[0034] In a pressurized liquid supply device (100) including multiple storage containers (105), the discharge phenomenon generally shows a high discharge amount in the storage container (105) where the internal differential pressure is smallest among the N storage containers. If there is only one storage container (105) where the internal differential pressure is minimized, liquid is supplied only from that storage container. Therefore, in order to mitigate unbalanced discharge in an environment utilizing multiple storage containers (105), the difference in discharge amount between multiple storage containers (105) can be managed to be less than or equal to the design value in all operating environments as shown in FIG. 2 by configuring the installation of a first differential pressure control orifice (106) and a second check valve (108) as shown in FIG. 1.

[0035] That is, the balanced discharge method of the pressurized liquid supply device (100) including a plurality of storage containers (105) according to the present invention is designed based on the flowchart of FIG. 3, and after analyzing the supply pressure, flow rate, and operating time which are requirements of the pressurized liquid supply device (100) and completing the design of components regarding the pressurized system and storage containers (105), the design values ​​of the first and second differential pressure regulating orifices (106) (107) and the second check valve (108) for equal discharge are selected.

[0037] This is derived from the characteristic that the flow rate passing through the first and second differential pressure regulating orifices (106) (107) is proportional to the square root of the differential pressure.

[0038] And the differential pressure of the second differential pressure regulating orifice (107) ) is selected as a condition in which the minimum supply pressure of the test specimen (110) is maintained when the maximum flow rate is supplied from the pressurized liquid supply device (100).

[0039] The design results of the first and second differential pressure regulating orifices (106) (107) and the second check valve (108) as described above are explained by the operating principle of the equal discharge system presented in FIG. 2, and the upstream pressure of the second differential pressure regulating orifice (107) is the regulating pressure of the pressure regulator (103). The maximum internal differential pressure of the storage container (105) in ) ) and the differential pressure of the first differential pressure regulating orifice (106) This is a description of the criteria for maintaining the rated flow rate of the first differential pressure control orifice (106) even when considering the situation.

[0040] Consequently, even if the internal differential pressure occurs differently in each of the multiple storage containers (105) as shown in FIG. 2, the differential pressure of the first differential pressure adjusting orifice (106) ) is the internal differential pressure reference value of the storage container (105) ( About ) When designed as a relationship, the maximum discharge difference between storage containers (105) is controlled to be N% or less.

[0041] In addition, the differential pressure of the second differential pressure adjusting orifice (107) ) is the minimum internal differential pressure of all storage containers (105) ( Even under the maximum flow rate conditions of the system that appear when having ), the minimum supply pressure required by the test specimen (110) It is designed so that ) is maintained, and accordingly, the flow rate supplied to the test specimen (110) is It has a range.

[0042] At this time, The standard value of the supply flow rate of the test specimen (110) for the range can be expressed as follows using a mathematical formula.

[0043]

[0044] Here, is the standard value of the supply flow rate of the test specimen (110), is the internal differential pressure reference value of the storage container (105), is the differential pressure of the first differential pressure regulating orifice (106).
