Definitions
- This invention relates to a multi-purpose beam for use in a space environment to support a human habitat module or other space structure.
- the multi-purpose beam functions to provide structural support, facilitate airflow, and provide a housing to protect conduits while at the same time allowing access to the conduits.
- Structural supports are well known in the building trade and have been used in a number of applications.
- One important application of structural beams is in of the construction of space related crafts. In this environment, the beam can take a number of forms. One such form is that of a longeron.
- a longeron is a framing member that runs fore and aft on a structure such as a space based human habitat module.
- a structure such as a space based human habitat module.
- longerons there are usually a number of longerons that are at the structural core of modular space habitats.
- Another application of the beam is as a cross member attached to longerons, or as structural support to other elements of the habitat.
- the use of beams in such situations deals with the forces on a structure.
- the module experiences significant stresses from a number of sources. For example, load stresses due to the mass of equipment interacting with the beams. Also, internal forces due to the pressurization in the case of an inflatable modular habitat. Further, externally applied loads such as those experienced during docking maneuvers or linear attachment of other modules.
- a framework of rigid beams can accomplish this task.
- a structural member is part of the framework that provides a substantially rigid foundation. This can be, for example, part of the structural core, or a translation tube, in the case of an inflatable module.
- the conduit takes the form of a cable.
- the conduit usually takes the form of a hose or pipe.
- the module's oxygen supply could be displaced resulting in an undesirably lower level of oxygen. Should an oxygen leak occur, then the oxygen rich environment could increase the risk of a fire starting or should a fire occur it might not be easily controlled.
- While structures that support and direct a conduit are generally known as illustrated by U.S. Pat. No. 6,557,807 to Belanger, U.S. Pat. No. 6,467,734 to Brown, U.S. Pat. No. 5,947,424 to Heath, U.S. Pat. No. 5 , 823 , 484 to Barnard, U.S. Pat. No. 5,785,457 to Thompson, and U.S. Pat. No. 4,961,553 to Todd, these patents do not claim, disclose, or intimate the use of a structural member to provide protection to the conduit.
- the multi-purpose beam has a tubular like structural member with a cross section being generally oval, circular, box, triangular, or polygonal, or a combination thereof.
- a plurality of dividers inside the tubular like structural member that extend the length of the tubular like structural member and divide the inside into a number of cavities.
- At least one cavity is adapted to direct an airflow and another cavity is adapted to receive a conduit.
- the conduit can be a power cable, pipe, hose, or any other type of channel through which something is conveyed.
- One or more openings extend from at least one cavity through the tubular like structural member's external periphery.
- FIG. 1 is an isometric view of the multi purpose beam with dividers, openings and one conduit;
- FIG. 2 is an isometric view of the multi purpose beam with dividers and openings and two conduits;
- FIG. 3 is an isometric cut away view of the multi purpose beam identifying the holes between two adjoining cavities
- FIG. 4 is a side view of a multi purpose beam conFig.d as a longeron and providing air, power, and water;
- FIG. 5 is a cross sectional view of the elongated tubular like structural member exhibiting a generally circular cross section;
- FIG. 6 is a cross sectional view of the elongated tubular like structural member exhibiting a generally oval cross section;
- FIG. 7 is a cross sectional view of the elongated tubular like structural member exhibiting one of a variety of polygonal cross sections;
- FIG. 8 is a cross sectional view of the elongated tubular like structural member exhibiting a generally rectangular cross section
- FIG. 9 is a cross sectional view of the elongated tubular like structural member exhibiting a generally square shape
- FIG. 10 is a cross sectional view of the elongated tubular like structural member exhibiting a generally triangular shape
- FIG. 11 is a cross sectional view of the elongated tubular like structural member exhibiting a shape that is a combination of geometric forms;
- FIG. 12 a is an isometric view of four individual shafts
- FIG. 12 b is an isometric view of the elongated tubular like structural member composed of four joined shafts.
- FIG. 13 is an isometric view of a shaft and a skeletal structure.
- FIG. 1 is an isometric view of the multi purpose beam 10 .
- the multi purpose beam 10 is composed of an elongated tubular like structural member 12 having a plurality of dividers 14 within the tubular like structural member 12 extending the length 13 of the member 12 and thereby defining a number of cavities 16 where at least one cavity 16 contains a conduit 18 .
- the cavities 16 are enclosed hollow areas extending the length 13 of the member 12 .
- the cavities 16 are surrounded by sides defined by the tubular like structural member 12 and the dividers 14 . Enclosing the cavities 16 in this manner provides an extra measure of protection for the conduits 18 that are within the cavities 16 .
- Extending from the cavities 16 through the external periphery 20 are a plurality of openings 22 . These openings 22 serve a number of purposes. First, in the case where air is channeled through a cavity 16 as shown in FIG. 1, the openings allow airflow 15 in and out of the cavity 16 . In this way, the cavity 16 directs the airflow 15 to provide air to the modular human habitat. While it may be desirable in some instances to direct other gases through the cavity 16 , the term airflow can include air, oxygen, nitrogen or any other gas or combination of gases as needed in the particular application.
- a conduit 18 is a channel through which something is conveyed.
- a conduit 18 can convey liquids, gases, and electricity.
- the openings 22 assist in reducing the overall weight of the tubular like structural member 12 .
- the location and number of openings 22 are chosen as not to degrade the structural integrity of the tubular like structural member 12 in the desired application.
- FIG. 2 a second conduit 18 is shown residing within a cavity 16 .
- the enclosure around the conduit formed by the dividers 14 and the tubular like structural member 12 allow a user to place specialized conduits 18 within a cavity.
- a liquid conduit 18 such as a hose or pipe that transports water.
- Another cavity 16 may only have conduits 18 for transporting electricity.
- the cavities 16 form an extra barrier between the water and electrical conduits 18 . This is a safety feature of the multi purpose beam 10 .
- part of the tubular like structural member 12 is removed to expose the holes 26 that exist between two adjoining cavities 28 that share a divider 14 .
- the adjoining cavities 28 direct airflow 15 through the cavities 28 and the holes 26 act to equalize the pressure between the adjoining cavities 28 and to better facilitate a more even distribution of heat vis-a-vis the airflow 15 .
- the geometry of the holes is dependent upon the application and is not limited to that identified in the figure.
- FIG. 3 also identifies an access port 30 .
- the access port 30 attaches to the conduit 18 to facilitate transfer of whatever the conduit 18 is conveying.
- the access port 30 conveys the liquid from the conduit 18 through the external periphery 20 to make the water available to a user.
- the access port could be a water valve.
- one conduit can supply the water and another conduit can remove the water.
- the access port 30 takes the form of an electrical outlet to make electricity available beyond the external periphery 20 . It naturally follows that where the conduit is transferring a gas, such as nitrogen or oxygen, the access port 30 may take the form of a valve attached the conduit 18 , which may be a hose or pipe. In this application, the access port 30 can be a valve that transfers the gas from the conduit 18 or into the conduit 18 .
- an access port 30 that connects through an opening to a conduit 18 such that a liquid or gas is accessible through the access port 30 means the gas or liquid can be coming from the conduit 18 and external to the elongated tubular like structural member 12 or going into the conduit 18 .
- the multi purpose beam 10 takes the form of a longeron 31 .
- a longeron is a fore and aft framing member of a structure such as a modular space habitat.
- the longeron 31 connects two end caps 32 as would be common in a singular human habitat module in space.
- the access ports 30 are shown to provide electricity through electric cables 34 to computers 36 and other pieces of electrical equipment 38 and water through water hoses 40 for transferring heat from the electrical equipment 38 .
- Airflow 42 is shown as the air forced through the cavities escapes through the openings 22 into the module. While FIG. 4 identifies a longeron 31 , the multi-purpose beam is not limited in its application to just a longeron.
- the multi-purpose beam can be used as a frame, support, or in any capacity that requires a structural brace or foundation.
- FIG. 5 is generally a circular 44 cross section 13 .
- FIG. 6 is generally an oval cross section 42 .
- FIG. 7 is generally a polygon having six sides, a hexagon, although a polygonal cross section 50 is not limited to only six sides.
- FIG. 8 shows a generally rectangular cross section 43 .
- FIG. 9 is generally a box cross section 46 .
- FIG. 10 identifies a generally triangular cross section 48 .
- FIG. 11 is an example of a combination of a generally semicircular and generally square cross section 52 .
- the cross section 13 can take a shape as required by the situation and is not limited to those specifically identified. Further, FIGS. 5 through 9 depict how the dividers 14 can be in a variety of positions. None in this specification is intended to limit the number of dividers 14 or the various positions that the dividers can take within the member 12 .
- FIG. 12 a identifies the case where four shafts 54 are used, however this does not restrict the number of shafts 54 that can be used.
- Each shaft 54 has a length 56 , an external periphery 58 , and at least one wall 60 defining a cavity 16 .
- Each shaft 54 can take a variety of cross sections 13 as described in FIGS. 5 through 11.
- One wall 60 of each shaft 54 adjoins a wall 60 of another shaft 54 . These form the adjoining walls 62 .
- the shafts 54 are composed of aluminum, but may also be of an aluminum alloy, other generally metallic material, metallic alloy, or a composite material.
- the adjoining walls 62 are fixedly attached, or joined, to one another.
- the attachment can be facilitated by a number of well-known means including welding and/or bonding with materials having, for example, an epoxy base.
- bonding can be achieved by use of materials such as, again, an epoxy based substance.
- At least one shaft 54 contains a plurality of openings 22 extending from the cavity 16 through the wall 60 and external periphery 58 .
- at least one cavity 16 is adapted to conduct airflow 15
- at least one cavity 16 is adapted to receive a conduit 18 .
- a divider 14 is disposed within, and along the length 56 , of a shaft 54 to produce a plurality of cavities 16 .

Abstract
A multi-purpose beam for providing structural support to an assembly, an added measure of protection for conduits such as lines, hoses, and cables, and directs airflow. The inside of the beam has a number of cavities running the length of the beam created by a plurality of dividers. Within these cavities air can be circulated and conduits can be contained that transfer liquids, gases, and power. The shell of the beam and the dividers add a protective layer supporting the conduits and a plurality of openings allows for access ports that tap into the conduits at desirable locations along the length of the beam thus making what ever is conducted by the conduits available external to the multi-purpose beam.
Description
- 1. Field of the Invention
- This invention relates to a multi-purpose beam for use in a space environment to support a human habitat module or other space structure. The multi-purpose beam functions to provide structural support, facilitate airflow, and provide a housing to protect conduits while at the same time allowing access to the conduits.
- 2. Description of the Prior Art
- Structural supports are well known in the building trade and have been used in a number of applications. One important application of structural beams is in of the construction of space related crafts. In this environment, the beam can take a number of forms. One such form is that of a longeron.
- A longeron is a framing member that runs fore and aft on a structure such as a space based human habitat module. In application, there are usually a number of longerons that are at the structural core of modular space habitats.
- Another application of the beam is as a cross member attached to longerons, or as structural support to other elements of the habitat. The use of beams in such situations deals with the forces on a structure.
- In space applications such as a modular human habitat, the module experiences significant stresses from a number of sources. For example, load stresses due to the mass of equipment interacting with the beams. Also, internal forces due to the pressurization in the case of an inflatable modular habitat. Further, externally applied loads such as those experienced during docking maneuvers or linear attachment of other modules.
- The aforementioned stresses identify the need for a rigid structure. A framework of rigid beams can accomplish this task. In the case of a modular habitat, a structural member is part of the framework that provides a substantially rigid foundation. This can be, for example, part of the structural core, or a translation tube, in the case of an inflatable module.
- While the use of beams is critical to the construction of a module in space, there is an overriding consideration that severely restricts widespread application of beams in that environment. This is due to the weight associated with structural beams.
- The cost to place a structure in space is extremely high. This cost rises in relation to the increase in the weight of the structure launched. Since beams provide structural support, they tend to be heavy and this weight increases the cost associated with a launch of the beams, and the overall space module, into space.
- While recent advances have been made in the use of composites that are lighter in weight and still provide structural support, they too have drawbacks. For example, it is not uncommon for composites to be very expensive. Another drawback is that many composites may work well in one structural application and not in another. Further, some composites are not as easy to work with as traditional structural materials such as aluminum. Even so, solid composite beams may still be too heavy for use in a space environment.
- One way to reduce the weight of the beam has been to hollow out the beam. While hollow beams for structural support are well known as typified by U.S. Pat. No. 6,554,352 to Nagy, they have not been adapted to perform a multiplicity of functions and the internal space, or cavity, remains largely unused.
- Equally well known are systems that transport water, gas, and electricity. Typically this is accomplished by use of a conduit.
- In the case of electrical current, the conduit takes the form of a cable. With regards to transferring liquids, such as water, or gases, such as oxygen or nitrogen, the conduit usually takes the form of a hose or pipe.
- Use of cables, pipes, and hoses in space based applications present unique challenges. In a micro-gravity environment, a leak of a liquid or gas can be catastrophic. This is due to the fact that the leaking material is driven by the force in the container as it is ejected.
- Without a gravitational point of reference, solid materials do not stop moving until they make contact with another object. This could be an electrical panel, a person, or sensitive and necessary equipment on the module. Such contact can be dangerous.
- In the case of a leaking gas, such as nitrogen, the module's oxygen supply could be displaced resulting in an undesirably lower level of oxygen. Should an oxygen leak occur, then the oxygen rich environment could increase the risk of a fire starting or should a fire occur it might not be easily controlled.
- As to the transfer of electricity, a cable failure could result in fire, critical system failures due to circuit shorts, failure of expensive experiments, or even electrocution.
- Many such problems can result from damaged conduits. One solution is to use highly durable and failure resistant conduits. The down side to this approach is that such conduits are more expensive and typically heavier and less user friendly.
- While structures that support and direct a conduit are generally known as illustrated by U.S. Pat. No. 6,557,807 to Belanger, U.S. Pat. No. 6,467,734 to Brown, U.S. Pat. No. 5,947,424 to Heath, U.S. Pat. No.5,823,484 to Barnard, U.S. Pat. No. 5,785,457 to Thompson, and U.S. Pat. No. 4,961,553 to Todd, these patents do not claim, disclose, or intimate the use of a structural member to provide protection to the conduit.
- One other issue is the availability of air in a space environment. Terrestrially, airflow can be directed by use of air ducts. However, in a space environment, where every square inch counts, the addition of air ducts does not provide an optimum solution.
- What is needed is a lighter and more versatile beam, a more optimum way to direct airflow, and a way to protect conduits in a space environment. Thus, a structural member that encloses conduits and directs airflow would be ideal.
- The multi-purpose beam has a tubular like structural member with a cross section being generally oval, circular, box, triangular, or polygonal, or a combination thereof. There is a plurality of dividers inside the tubular like structural member that extend the length of the tubular like structural member and divide the inside into a number of cavities.
- At least one cavity is adapted to direct an airflow and another cavity is adapted to receive a conduit. The conduit can be a power cable, pipe, hose, or any other type of channel through which something is conveyed.
- One or more openings extend from at least one cavity through the tubular like structural member's external periphery.

- The present invention may best be understood by reference to the following description taken in conjunction with the accompanying drawings. FIG. 1 is an isometric view of the
multi purpose beam 10. Themulti purpose beam 10 is composed of an elongated tubular likestructural member 12 having a plurality ofdividers 14 within the tubular likestructural member 12 extending the length 13 of themember 12 and thereby defining a number ofcavities 16 where at least onecavity 16 contains aconduit 18. Thus, thecavities 16 are enclosed hollow areas extending the length 13 of themember 12. - As evident from FIG. 1, the
cavities 16 are surrounded by sides defined by the tubular likestructural member 12 and thedividers 14. Enclosing thecavities 16 in this manner provides an extra measure of protection for theconduits 18 that are within thecavities 16. - Extending from the
cavities 16 through theexternal periphery 20 are a plurality ofopenings 22. Theseopenings 22 serve a number of purposes. First, in the case where air is channeled through acavity 16 as shown in FIG. 1, the openings allowairflow 15 in and out of thecavity 16. In this way, thecavity 16 directs theairflow 15 to provide air to the modular human habitat. While it may be desirable in some instances to direct other gases through thecavity 16, the term airflow can include air, oxygen, nitrogen or any other gas or combination of gases as needed in the particular application. - Second, in the instances where the
cavity 16 contains aconduit 18, theopenings 22 allow access to theconduit 18 to facilitate transfer of whatever is being conducted thought theconduit 18 outside of themulti-purpose beam 10. Aconduit 18 is a channel through which something is conveyed. Thus, aconduit 18 can convey liquids, gases, and electricity. - Finally, the
openings 22 assist in reducing the overall weight of the tubular likestructural member 12. In concert with weight reduction, the location and number ofopenings 22 are chosen as not to degrade the structural integrity of the tubular likestructural member 12 in the desired application. - Turning now to FIG. 2, a
second conduit 18 is shown residing within acavity 16. The enclosure around the conduit formed by thedividers 14 and the tubular likestructural member 12 allow a user to placespecialized conduits 18 within a cavity. For example, on cavity may only have aliquid conduit 18 such as a hose or pipe that transports water. Anothercavity 16 may only haveconduits 18 for transporting electricity. Thus, thecavities 16 form an extra barrier between the water andelectrical conduits 18. This is a safety feature of themulti purpose beam 10. - Addressing FIG. 3, part of the tubular like
structural member 12 is removed to expose theholes 26 that exist between two adjoiningcavities 28 that share adivider 14. The adjoiningcavities 28direct airflow 15 through thecavities 28 and theholes 26 act to equalize the pressure between the adjoiningcavities 28 and to better facilitate a more even distribution of heat vis-a-vis theairflow 15. The geometry of the holes is dependent upon the application and is not limited to that identified in the figure. - FIG. 3 also identifies an
access port 30. Theaccess port 30 attaches to theconduit 18 to facilitate transfer of whatever theconduit 18 is conveying. In the case of liquids, such as water, theaccess port 30 conveys the liquid from theconduit 18 through theexternal periphery 20 to make the water available to a user. In this case, the access port could be a water valve. - In the situation where the water is being provided to regulate the heat produced by equipment, one conduit can supply the water and another conduit can remove the water.
- Where the
conduit 18 conveys electricity, such as an electrical cable, theaccess port 30 takes the form of an electrical outlet to make electricity available beyond theexternal periphery 20. It naturally follows that where the conduit is transferring a gas, such as nitrogen or oxygen, theaccess port 30 may take the form of a valve attached theconduit 18, which may be a hose or pipe. In this application, theaccess port 30 can be a valve that transfers the gas from theconduit 18 or into theconduit 18. - By definition, an
access port 30 that connects through an opening to aconduit 18 such that a liquid or gas is accessible through theaccess port 30 means the gas or liquid can be coming from theconduit 18 and external to the elongated tubular likestructural member 12 or going into theconduit 18. - Focusing now on FIG. 4, the
multi purpose beam 10 takes the form of alongeron 31. A longeron is a fore and aft framing member of a structure such as a modular space habitat. In FIG. 4, thelongeron 31 connects twoend caps 32 as would be common in a singular human habitat module in space. Theaccess ports 30 are shown to provide electricity throughelectric cables 34 tocomputers 36 and other pieces ofelectrical equipment 38 and water throughwater hoses 40 for transferring heat from theelectrical equipment 38.Airflow 42 is shown as the air forced through the cavities escapes through theopenings 22 into the module. While FIG. 4 identifies alongeron 31, the multi-purpose beam is not limited in its application to just a longeron. The multi-purpose beam can be used as a frame, support, or in any capacity that requires a structural brace or foundation. - FIGS. 5 through 11 exemplify a variety of cross sections13 of the tubular like
structural member 12. FIG. 5 is generally a circular 44 cross section 13. FIG. 6 is generally anoval cross section 42. FIG. 7 is generally a polygon having six sides, a hexagon, although apolygonal cross section 50 is not limited to only six sides. FIG. 8 shows a generallyrectangular cross section 43. FIG. 9 is generally abox cross section 46. FIG. 10 identifies a generallytriangular cross section 48. Finally, FIG. 11 is an example of a combination of a generally semicircular and generallysquare cross section 52. - The cross section13 can take a shape as required by the situation and is not limited to those specifically identified. Further, FIGS. 5 through 9 depict how the
dividers 14 can be in a variety of positions. Nothing in this specification is intended to limit the number ofdividers 14 or the various positions that the dividers can take within themember 12. - Addressing now FIG. 12a, the preferred embodiment begins with a plurality of hollow
elongated shafts 54. FIG. 12a identifies the case where fourshafts 54 are used, however this does not restrict the number ofshafts 54 that can be used. Eachshaft 54 has alength 56, anexternal periphery 58, and at least onewall 60 defining acavity 16. Eachshaft 54 can take a variety of cross sections 13 as described in FIGS. 5 through 11. Onewall 60 of eachshaft 54 adjoins awall 60 of anothershaft 54. These form the adjoiningwalls 62. Theshafts 54 are composed of aluminum, but may also be of an aluminum alloy, other generally metallic material, metallic alloy, or a composite material. - Turning now to FIG. 12b, the adjoining
walls 62 are fixedly attached, or joined, to one another. Where theshafts 54 are composed of aluminum, the attachment can be facilitated by a number of well-known means including welding and/or bonding with materials having, for example, an epoxy base. In the case where theshafts 54 are made of a composite substance, bonding can be achieved by use of materials such as, again, an epoxy based substance. At least oneshaft 54 contains a plurality ofopenings 22 extending from thecavity 16 through thewall 60 andexternal periphery 58. Also, at least onecavity 16 is adapted to conductairflow 15, while at least onecavity 16 is adapted to receive aconduit 18. - When the
shafts 54 are joined, the walls perform the same function as thedividers 14 in FIGS. 1 through 3. That is, thewalls 60 define thecavities 16 of the elongated tubular likestructural member 12. Referring again to FIGS. 12a and 12 b, adivider 14 is disposed within, and along thelength 56, of ashaft 54 to produce a plurality ofcavities 16. A plurality ofdividers 14 can be utilized in theshafts 54 as desired. Adivider 14, or any number ofdivders 14, can be secured within ashaft 54 by a variety of ways including those described above for joining theshafts 54 together. The joinedshafts 54 and inserted dividers then define the elongated tubular likestructural member 12. - Turning again to FIG. 12b, a
conduit 18 is identified within acavity 16. Furthermore, anaccess port 30 is shown that accesses whatever is being conducted by theconduit 18. As described above, theaccess port 30 can take whatever form is necessary to distribute whatever is conducted by the conduit outside of themulti-purpose beam 10 and in the case of a liquid or gas theaccess port 30 can be used to direct the liquid or gas into theconduit 18. Further, FIG. 12b identifies twocavities 16 conducting anairflow 15 and holes 26 that allow the flow of air to pass between the adjacent connected cavities. - FIG. 13 identifies how the
dividers 14 can be utilized to form askeletal structure 64. Theskeletal structure 64 is then inserted bydirection 63 into the hollow interior of the elongated tubular likestructural member 12. Thus, a plurality ofcavities 16 exist within themember 12. Theskeletal structure 64 is fixedly attached in place to the elongated tubular likestructural member 12 by well known means such as welding and bonding with materials having an epoxy base. - A multi-purpose support beam as disclosed herein does not necessarily depend upon
independent shafts 54, independentskeletal structures 64, orindependent dividers 14. Techniques such as, but not limited to, injection molding can produce a multi-purpose beam without relying on independent parts. - There has thus been described a novel multi-purpose beam. It is important to note that many configurations can be constructed from the ideas presented. Thus, nothing in the specification should be construed to limit the scope of the claims.
