Piece-rate system

Technical field

Present invention relates in general to a kind of piece-rate system, relate to a kind of piece-rate system that first segment is separated from second joint especially.

Background technology

Industrial at carrier rocket, developed various piece-rate systems for many years and isolated capacity weight rectifying device (payload fairings), facilitated the use thereby remove the lid that comprises any spacecraft within it thus from carrier rocket.At this on the one hand, adopted a disengagement gear and wire separation system that the capacity weight rectifying device is separated from carrier rocket for many years.

A main design considers it is not only to be the carrier rocket piece-rate system, and for other piece-rate system provides a kind of system, and this system will cause described separated structure and not collide with being retained between the structure.For example, in carrier rocket industry, piece-rate system is removed capacity weight rectifying device structure come out and avoided any collision between them from carrier rocket is very important.Yet the occasion of bulky construction designs the piece-rate system of this crash-avoidance and has become more and more difficult adopting big.

Summary of the invention

Therefore, the purpose of this invention is to provide a kind of piece-rate system.

Another object of the present invention provides a kind of piece-rate system, and this system causes the thorough separation of a structure with respect to another structure.

Another purpose of the present invention provides a kind of piece-rate system, and this system causes one first structure to be separated with respect to the collisionless substantially of one second structure.

A further object of the invention provides a kind of piece-rate system, and this system forms the separation vibrations that reduce.

Another object of the present invention provides a kind of piece-rate system, and this system has reduced the chance that fragment and pollutants occur separating.

The present invention reaches described one or more purpose by a piece-rate system that first structure is separated from second structure is provided.Usually, according to one aspect of the present invention, described piece-rate system comprises first and second framing members (for example doubler (doubler) or doubler plate), at first and second grooves that are provided with on described first and second framing members and the explosive that between described first and second framing members, comprises, described framing member is at least one to begin to interconnect described first structure and second structure, described first framing member and described second framing member are separated, described explosive be used for breaking first and second framing members at the first and second area of fracture places that determined by corresponding first groove on described first and second framing members and second groove.Importantly, described first and second grooves are relative to each other removed or are staggered (for example, non-coplane), so that first and second area of fractures on described first and second framing members are relative to each other setovered or (for example offseted respectively, non-coplane), so that avoid undesirable contact between them.In addition, in order to strengthen the destruction of described first and second framing members,, described first and second grooves can be arranged on the detonation front offside and/or the non-detonation front offside of described first and second framing members according to the ad hoc structure spare that is provided with groove thereon.

For the separation that helps described first and second framing members with avoid undesirable contact or big collision between them when separating, in one embodiment, first groove on first framing member is along one the first tangent plane setting of being determined by described exploder, second groove on second framing member be configured such that described second groove and this exploder at least the position aimed at of a part.For example, second groove on second framing member can be aimed at being aligned with the core of the exploder explosive heart, so that when lighting described exploder and expand into a circular contour, described second framing member will destroy or rupture.In another embodiment, corresponding on described first and second framing members staggered first and second grooves all along the tangent plane setting of determining by described exploder.This tangent plane can by described exploder first and second parts determine (for example under blast state not described exploder end).In this, the first and second biasing area of fractures of being determined by the corresponding first and second biasing grooves on first and second framing members can be consistent with first and second tangent planes of being determined by described exploder substantially.In these embodiment of piece-rate system of the present invention, in the time lighting exploder, described first and second framing members or doubler destroy at its thin spot place or separately (for example, setover or staggered groove places described first and second).Because the biasing of described first and second grooves or be staggered, help described first and second joint or the collisionless relatively separation of structure in the time lighting described exploder, because reduced the unfavorable contact between the described first and second framing member separating parts.

This piece-rate system needing to be used in particular for the situation of first structure with respect to the separation of second structure.At this on the one hand, the present invention allows when lighting exploder and makes after the separation of first and second framing members separating part at described first and second framing members not have unfavorable collision each other or with exploder collisionless under swelling state or do not damage under each other the situation, described first structure is separated with respect to described second structure.For example, (for example has first structure, the capacity weight rectifying device, door, window, it is fluffy, spacecraft etc.) and second structure (center carrier rocket for example, the earth base rocket, aerial base rocket or seabase rocket) rocket along first direction (for example, along the longitudinal axis of rocket or the sense of motion of rocket) when mobile, by adopting piece-rate system of the present invention, along at least one second direction (for example can cause described first structure with respect to second structure, at least laterally with respect to the longitudinal axis of rocket or at least orthogonally with respect to the direction of rocket) separation, can not produce disadvantageous the contact, so that described first structure is freely separated (for example by spray) on described second structure with described second structure.At this on the one hand, the separating part of described first and second framing members do not have unfavorable collision each other or hang up mutually or and expanded and do not had between the blasting explosive container under the unfavorable case of collision, described first structure can be at least along second direction (for example, at least laterally) with respect to separating along second structure of the first direction at least longitudinal axis of rocket (for example, along).Like this, the present invention is by disconnecting described first and second framing members in the time lighting exploder, the separation of described first and second framing members not only is provided, and by providing at least biasing or staggered first and second grooves to reduce not wish the possibility that contacts, this helps the separation of described first and second framing members at the first and second area of fracture places, and described first area of fracture and second area of fracture are setovered or offseted.

In a word, for the cut-out of strengthening described framing member or doubler separates and first structure and second structure separating relative to each other, first and second surfaces that described first groove is arranged on first framing member (for example, detonation front offside and non-detonation front offside) a surface, be arranged in the first of described first framing member and determine a failure line to pass this first framing member, first and second surfaces that described second groove is arranged on second framing member (for example, detonation front offside and non-detonation front offside) a surface on, be arranged on the second portion of described second framing member and determine one second failure line to pass this second framing member.The first of described first framing member is along the biasing of the second portion of the first direction and second framing member or offset.In this and since described first and second be staggered groove by relative set on first and second parts of first and second framing members, so just help at least along the relative collisionless separation of the second direction of first structure with respect to second structure.

According to one aspect of the present invention, in order further to increase the chance of the relative collisionless separation between first and second structures, the power that reduces to need destruction and crooked described framing member is to help this separation, and described first and second framing members (for example doubler plate) can be shaped as or tend to around a selection area bending or be hinged in the selection area.At this on the one hand, by the reinforcement bending apparatus is provided, the bending of described first and second framing members can be reinforced and control to a certain degree in the time lighting exploder.In one embodiment, strengthen bending apparatus and comprise a reinforcing section at least one first and second framing member or doubler, to help of the bending of this first and second framing member around selected portion, simultaneously, help described first and second framing members for example corresponding first and second destructions that are staggered the groove place.At this on the one hand, described first and/or the thickness of this reinforcing section of second framing member greater than at first and second thickness of first and/or second framing member that are staggered the groove place.This reinforcing section can comprise the described doubler that is connected to first and/or second framing member with or a reinforcement that separates doubler plate or stiffener.In another embodiment, the reinforcement bending apparatus is included in the crooked release portion of at least one first reinforcement at least one first and second framing member.When destroying at least one first and second framing member when lighting described exploder and at its part place of leaving the crooked release portion of described reinforcement, the crooked release portion of this reinforcement helps in described first and second framing members to center on release portion or the bending in release portion or hinged.About this point, described one or more release portions have been determined the thickness in described first and/or second framing member, and this thickness is less than the thickness of described first and/or second framing member of other parts.This release portion can be set at the top or lower part of the non-blast opposed face of these framing members, helps described framing member bending away from this exploder further ought light exploder the time.Described first and/or second framing member have vulnerable part or groove separate with the failure line that helps this first and/or second framing member to determine along this groove and also comprise one or more release portions to help firing exploder the time crooked described first and/or the situation of second framing member under, at the thickness of the framing member at release portion place thickness greater than the framing member at groove place.At this on the one hand, described framing member will separate thereby allow described first segment to save from second joint with respect to second in advance described groove place destruction and in described release portion bending.

In another embodiment, piece-rate system further comprises one and sliding surface device of at least the first framing member bonded assembly.Importantly, when by lighting described exploder and will be described at least after first framing member separates, described sliding surface device be used at least onely beginning to guide one of described first and second joints away from wherein another.At this on the one hand, since described sliding surface device along the wherein joint in predetermined face determining by the sliding surface device or channel lead first and second joints away from another joint, so described sliding surface device helps first segment to separate with respect to the relative collisionless of second joint.In this embodiment, described sliding surface device comprise be connected to described first and second the joint in wherein one the joint at least one first sliding part.Fire the destructiveness contact between the separating part of described first and second framing members behind the explosion unit for inhibition point, described sliding surface device and above-mentioned first and second be staggered in the groove one of them aim at being aligned or coplane.Further, begin to guide described first segment (they connect the described first segment and second joint at the beginning) can not contact each other nocuously so that the separating part at least one first and second framing member away from second joint at least one, described first sliding part is orientated between about 1 ° to about 90 ° with respect at least one first and second framing member.For example, has first segment (capacity weight rectifying device for example, capacity weight, door, window, it is fluffy, spacecraft etc.) and second joint (the center carrier rocket for example, the earth base rocket, aerial base rocket or seabase rocket) rocket along first direction (for example, when the longitudinal axis along rocket) mobile, by adopting at least the first sliding part of piece-rate system of the present invention, can cause described first segment with respect to the separation of second joint along at least one second direction (for example at least laterally with respect to the longitudinal axis of rocket), the substance that the described first segment or second joint can not occur is destroyed.More specifically, at rocket (for example along first direction, along the rocket y direction) motion situation under, at least at the very start guide described first segment away from second joint along second direction at least in part with respect to described first direction into about first sliding part of angle between 1 ° to about 90 °, so that suppress undesirable contact between the separating part of described first and second framing members.Like this, the present invention not only provides the separation of first and second structures, and reduces the possibility that the substance that caused by collision is destroyed by providing described at least first sliding part to guide described first segment away from second joint.

In another embodiment, described sliding surface device comprises first and second relative sliding part or the sliding matses, is used for guiding described first segment afterwards away from second joint by lighting described first and second framing members separation of exploder.In this embodiment, described first and second sliding parts define a sliding surface, this sliding surface is aimed in line with first groove on first framing member or coplane basically, this sliding surface with under blast state not by described exploder the first tangent plane coplane that limits of first end.Especially, described first and second sliding matses interconnect with first and second joints respectively, and bearing fit mutually.At this on the one hand, when lighting exploder and after separating at least one first and second framing member, this first and second pad is used at least one beginning and guides described first segment away from second joint along at least one first burbling area of being determined by this first and second pad.For example, under the situation that second joint of wanting to make first segment at least laterally vertically move with respect to separates, described first and second sliding matses can be orientated in about 90 ° scope at about 1 ° with respect at least one first and second joint or with respect at least one first and second framing member.In one embodiment, first and second sliding matses are with respect to the about 90 ° of orientations of at least one first and second framing member, to help described first segment direction the moving away from described second joint of an at least one beginning perpendicular at least one described first and second framing member.Separate in order further to strengthen this guiding, at least coating one deck low-friction coating on one of first and second sliding matses.

In one embodiment of the invention, shown in Fig. 2 A-2C, described piece-rate system 20 comprises that first and second framing members or 26,30, one of doublers have in the extension pipe explosive charge system of the explosive 36 of splendid attire between described first and

second doublers

26,30 and place first and

second grooves

40,44 on described first and

second doublers

26,30 respectively.Described first and

second doublers

26,30 link to each other with described first and second joints or

structure

48,52, and for example the core with a capacity weight rectifying device and described carrier rocket is corresponding respectively for described first and second joints.At this on the one hand, described piece-rate system 20 interconnects described first and

second joints

48,52 at least at first, then as following in further detail as described in, by damaging or fracture described first and

second doublers

26,30 and with respect to second joint 52 separately with described first segment 48.

Shown in Fig. 2 A, first and second joints, 48,52 at least one beginnings that will be separated by piece-rate system 20 of the present invention interconnect especially.About this point, first and

second doublers

26,30 of the present invention extend between described first and

second joints

48,52 that will be separated, and interconnect with it.This interconnecting can be finished by the mechanical fixed part as

bolt

56a, 56b, and described connecting element extends and inserts respectively in the hole of described first and

second doublers

26,30 and first and second joints 48,52.Determined that a cavity or space are with splendid attire explosive 36 between the

end

49,53 of described first and

second joints

48,52 and the

inwall

27,31 of described first and second doublers 26,30.This explosive 36 (for example holocentric line or double heart curve) can be contained in the elastic body 37, and described explosive and elastic body are contained in the expandable metal tube 38 together.This bulged tube 38 interconnects by a restraint strap 55 and described second joint 52, and when described explosive 36 lighted or during detonation by this detonation article of splendid attire, described inflatable metal tube 38 provides the separation of a described first segment 48 of free from contamination with respect to second joint 52.About this point, the detonation of described explosive 36 causes described pipe 38 to expand into a common circle.This expansion damage of described pipe 38 or described first and

second doublers

26,30 that fracture, as following will being described in detail, described first and

second doublers

26,30 are sheared and/or stretching action at first and second grooves, 40,44 places.In order to absorb the impact shock power that produces by firing of explosive 36, between the

end

second joints

48,52, insert an absorbing sheet 35 of for example making by silica gel.

In an embodiment shown in Fig. 2 A, first segment 48 for the ease of described longitudinal extension saves 52 horizontal at least separation with respect to second of longitudinal extension, and described first and

second grooves

40,44 are separately positioned on the

outer wall

28,32 of first and second doublers 26,30.Described first and

second grooves

40,44 provide thin spot on first and

second doublers

26,30, to have determined fracture or damage face whereby, when explosive blasting 36, first and

second doublers

40,44 will be along this area of fracture fracture.In this embodiment that Fig. 2 A describes, be spaced apart out with respect to second groove 44 on second doubler 30 at first groove 40 on first doubler 26.About this point, described first and

second grooves

40,44 are not in same plane (for example, biasing mutually) each other.And in this embodiment, first and second grooves, 40,44 quilts are placed on first and

second doublers

26,30 by the definite tangent plane of end 39a, the 39b of the not bulged tube 38 of splendid attire explosive 36 on the edge respectively.Especially, first groove 40 on first doubler 26 is aimed at the tangent plane that the first end 39a by bulged tube 38 not determines, and second groove 44 is aimed at the second end on the described pipe 38.The separation that this set of described first and

second grooves

40,44 helps first segment 48 to damage with respect to the relative nothing of second joint 52, this is because as described in Fig. 2 B-2C, the expansion of the pipe 38 during fired charge 36 make described first and

second doublers

26,30 disconnect in such a way and from the described pipe 38 bending leave, that is, so that allow described first segment 48 laterally to remove from described bulged tube 38 and the separating part 29a of first and

second doublers

26,30, the over top of 33a at least.

Fig. 2 B has described the piece-rate system 20 shown in Fig. 2 A after fired charge 36.Lighting of explosive 36 makes pipe 38 fire the effect of product and expand into a round section substantially owing to expanding gas.Like that, this expansion of pipe 38 makes first and second doublers, 26,30 parts produce distortion shown in Fig. 2 B, and makes the vulnerable part of first and

second doublers

26,30 at first and second grooves, 40,44 places rupture or break.Because described elastic body 37 has absorbed the many vibratory forcees that produced by explosive 36, so cause that the main power that pipe 38 expands is the high pressure that is produced by the expanding gas product in pipe 38.To the ignition of explosive 36 with light and to finish by the control circuit (not shown).

Shown in Fig. 2 B, after explosive 36 was lighted, the described first segment and

second joint

48,52 were separated.About this point, described first segment 48 is movably with respect to second joint 52.In one embodiment, need vertically move second joint 52 occasion of lateral separation at least at the described first segment 48 of needs with respect to one especially with respect to the

doubler

26,30 of the longitudinal extension occasion of lateral separation at least.Piece-rate system 20 of the present invention is useful especially avoiding the described first segment and second joint N/R contact and/or first segment and

second joint

48,52 between 48,52 with unfavorable contact the between the described bulged tube 38.At this on the one hand, because first and second doublers, 26,30 corresponding

broken ends

29a, 29b, 33a and 33b there is no fear of on the contrary collision each other or collide with described expanding metal pipe 38, described metal tube keeps interconnecting with second joint by restraint strap 55 in fired charge 36 back, thus first and

second grooves

40,44 correspondingly the chosen position on described first and

second doublers

26,30 be convenient to this separation.About this point, shown in Fig. 2 C, described first segment 48 can be freely and second joint 52 lateral separation at least.This lateral separation can be finished by a catapult-launching gear (not shown), and this device is used to promote described first segment 48, forces it laterally away from described second joint 52.

In an embodiment shown in Fig. 3 A-3C, in order to increase by the ignition of explosive 136 and to manage 138 expansion and the rupture failure power that produces, be convenient to the collisionless relatively separation of described first and second joints or doubler 126,130 simultaneously, with 140, the 144 mutual classifications spaced apart (on-plane surface) of described first and second grooves, and further they can be separately positioned on the detonation front offside and the non-detonation front offside 127,132 of described first and second framing members or doubler 126,130.In this embodiment, with along by described exploder the tangent plane determined of end different, second groove 144 can be arranged on the position at described bulged tube 138 and/or explosive 136 about centers.About this point, shown in Fig. 3 B, when when lighting explosive 136 described pipes 138 and expand into a round section, described second framing member 130 is because crooked and tension failure substantially.In addition, the possibility of separating with respect to second joint, 152 collisionlesss for first segment 148 shown in increasing can described first groove 140 be arranged on first framing member 126 along the definite tangent plane of end 139a by the expandable tubular 138 (under the state of non-blast) of splendid attire explosive 136.This set of the groove 140,144 that described classification separates has been strengthened the destruction of first and second framing members 126,130 and has been reduced vibration, and this is owing to need less power to make described doubler or framing member 126,130 rupture.Especially, because the crooked fracture of being convenient to described second framing member 130, so second groove 144 is arranged on the non-detonation front offside 132 of second framing member 130 near the position of this flare system core, this position moves to the tensile load zone with stress concentration.About this point, when explosive blasting 136 and cause managing 138 when expanding, described second doubler 130 will rupture under the effect of tensile force or destroy.Further, provide first doubler 126 (for example along a tangent plane of determining by unexpansive pipe 138 to the setting of described first groove 140 along the fracture of area of fractures on described bulged tube 138, explosive blasting 136 backs), this is convenient to the separation that the relative nothing between described first and second joints 148,152 is damaged.In case doubler 126,130 destroyed or distortion, shown in Fig. 3 B-3C, described first segment 148 freely separates with respect to second joint 152 substantially.Like this, this classification of described groove 140,144 be provided with at interval reduced several sections 129a, the 129b of first and second framing members 126,130 and 133a, 133b each other and/or and described bulged tube 138 between the N/R power that exists.

In another embodiment of the present invention that Fig. 4 A-4C describes, piece-rate system 220 of the present invention comprise will be separated first and second the joint 248,252 first and second framing members that are connected with each other or doublers 226,230, be separately positioned on first and second doublers 226, first and second grooves 240 of 230 blast opposed face and non-blast opposed face, 244, the explosive 236 of splendid attire in a bulged tube 238, this bulged tube is positioned at described first and second doublers 226, between 230 and want separated described first and second joints 248, between 252, and one by with described first and second the joint 248,252 interconnective first and second sliding parts 260, the 264 sliding surface devices that help this first segment 248 to separate that limit with respect to second joint, 252 relative collisionlesss.More particularly, in order along area of fracture first and second doublers 226,230 to be disconnected and to allow described first segment 248, first and second grooves 240,244 are separately positioned on the inside and outside wall 227,232 of first and second doublers 226,230 with respect to second joint, 252 relative collisionless lateral separation.The detonation front that described first and second grooves 240,244 is separately positioned on first and second doublers 226,230 causes occurring the tensile load zone that forms owing to crooked to wall and non-detonation front to wall 227,232, and this helps the destruction of doubler 226,230.Further, described first and second grooves 240,244 are staggered.In this, described first groove 240 be placed in substantially with by adorning the position that tangent plane that the end 239a of the expandable tubular 238 of explosive charge 136 not limits is aimed at.Described second groove 244 is positioned in the position of close bulged tube 238 cores of doubler 230 cores, with box lunch pipe 238 explode into along with lighting of explosive 236 this second doubler 230 when circular therein the heart partly rupture.This position of described first and second grooves 240,244 causes the destruction or the fracture of first and second doublers 226,230.About this point, with the relative to each other displacement or be staggered of described first and second grooves 240,244, to help of destruction or the fracture of first and second doublers 226,230, because this first and second groove 240,244 defines the weak area of first and second doublers 226,230 respectively at first and second grooves, 240,244 places.Similarly, lighting or exploding of explosive 236 causes that bulged tube 238 expansion bending also break apart described first and second doublers 226,230, therefore first segment 248 side travel on bulged tube 238 shown in Fig. 4 B, and this is restricted to second joint 252 in a conventional manner.In the fracture of first and second doublers 226,230 at described first and second grooves 240,244 places or destroy and allow described first segment 248 to separate with respect to the basic collisionless of second joint 252, this be because destruction part 233a, the 233b of the destruction of first doubler 226 end 229a, the 229b and second doubler 230 each other can be away from each other reason.
