    [0001] BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retractable method of embedding a tape measure for a deployable structure. It also relates to a deployable structure comprising a tape measure. It applies in particular to the field of space equipment that must be deployed in orbit and more particularly to space equipment for satellites, such as antennas, solar generators, heat shields, baffles or telescopes. The space-deployable structures, of the solar generator type, for example, generally consist of rigid panels 10 articulated together, these panels being, in the stored position, stacked one above the other. These structures have the advantage of having a controlled kinematics but have the disadvantage of a large surface mass and inertia. In addition, the rigid structures occupy, in the stored position, a large space under the cap of a launcher. The space 15 allocated to the deployable structures, under the cap of a launcher, being limited, it is important to reduce the bulk of these deployable structures when they are in the stored position so as to optimize the surface in the deployed position . There are flexible, deployable flat structures with a flexible web and tape measures (also known in the Anglo-Saxon literature as tape-spring) fixed on the same plane of the canvas. In the stored position, the fabric and the tape measures are wrapped around a mandrel. The deployment of the flexible flat structure is provided autonomously by the spontaneous unwinding of the tape-meters when the mandrel 25 is free to rotate. Indeed, the tape measures are known in the spatial field as being flexible tapes having a section in an arc whose radius of curvature is convex on a first face and concave on a second face, these tapes being able to pass from the wound state in the unwound state essentially due to their own elastic energy. There are different types of ribbon with their own properties. The monostable ribbons have a natural deployed position and require a hold in the stored position. Monostable tape measures therefore have a natural tendency to unfold to find themselves in their unrolled state. The deployment of monostable ribbons is often anarchic and uncontrolled. The bistable ribbons have two natural positions (stored position and extended position) and do not require maintenance in the stored position when the section is completely flattened. Their deployment is linear and controlled. However, in all cases, when the deployment is triggered, it may be violent and shock-producing, that is to say that the entire tape-measure may tend to go right simultaneously, along its length , which poses a risk of damage to the surrounding elements or elements fixed on the tape measure such as a flexible membrane, an instrument, an antenna ... The conventional tape meters may thus present difficulties in terms of control of their deployment. In order to regulate the deployment speed of this type of structure, several methods can be used. There may be mentioned for example a regulation by electric geared motor as described in the patent application FR12 / 03300 or a thermal regulation by using hybrid tape meters as described in patents FR 0803986 and US 7856735.
    [0002] In addition, the tape-meters do not have the same stiffness along the axis of stress. A force F applied on the convex face of the tape measure will have a tendency to bend the tape measure while the same force applied on the concave face will have no effect, which poses a problem of instability of the flexible structure in its unfolded state. To solve this problem of stability of the deployed state, it is then necessary to maintain the tape measure in the extended position by an additional holding device or to oversize the tape measure so that it remains stable under the orbital forces. whatever their application Thus, in stored configuration, the tape measure must be as compact as possible, that is to say have a winding radius as low as possible. This parameter is given by the physical characteristics of the ribbon, generally, the winding radius is substantially equal to that of their radius of curvature. In the case of a composite tape, it can be modified by changing the stack of folds and / or the direction of the fibers. In the extended configuration, the best possible rigidity is sought, which means a larger and more closed section possible associated with embedding the end of the tape-meter as much as possible.
    [0003] The invention aims at overcoming all or part of the problems mentioned above by proposing a retractable method of embedding a tape measure for a deployable structure, having the advantage of being compact, simple to implement, presenting an optimization of the the volume of the deployable structure when stored under the casing of a launcher, allowing the control of the deployment and a folding capacity and allowing rigidity and stability of the structure when deployed. To this end, the object of the invention is a retractable tape-measure embedding method for a roll-up and deployable structure, comprising a main tape measure having a deployment and folding axis substantially parallel to an unfolded axis X and having two ends, a secondary tape measure having two ends and a winding mandrel carried by a shaft parallel to an axis Z perpendicular to the axis X, the main tape being wound around the mandrel, a first end of main tape measure being fixed on the mandrel, characterized in that it comprises the following steps: - Fixing a first end of the secondary tape-tape away from a second end of the main tape-measure, 25 - fixing of a second end of the secondary tape measure on the mandrel. Advantageously, the retractable embedding method may comprise beforehand a point-fixing step of the second end of the main measuring tape. Advantageously, the method may comprise the following steps: - Simultaneous deployment of the main measuring tape substantially parallel to the X axis and the secondary tape measure, 3024227 4 - Formation of a triangulated structure between the main tape measure, the meter -secondary tape and mandrel. Advantageously, the method may further comprise a step 5 of re-winding the main tape-measure, and the re-winding of the main tape-measure may be obtained by buckling of the secondary tape measure. Advantageously, the main tape measure may comprise two faces, the first end of the secondary tape measure may be attached to a first face of the first end of the main tape measure, and the buckling of the secondary tape measure may be obtained by applying a force to the center of the tape measure and normal to the secondary tape measure. Advantageously, the force may be applied between the first end of the secondary tape measure and the second end of the main tape measure. Advantageously, the retractable embedding method may further comprise a step of fixing the first end of the main tape-meter 20 in the center of the mandrel. Advantageously, the deployable structure may comprise at least two rollers mounted in facing relation to the periphery of the mandrel, the rollers may be in contact with the main measuring tape, the rollers and the shaft may have a degree of freedom in rotation about the Z axis relative to each other. The retractable embedding method may comprise the following steps: local guidance of the main tape measure by the rollers; deployment of the main tape measure in a direction substantially parallel to the axis X. Advantageously, the rollers may be heating rollers, and the retractable embedding method may comprise a prior step of local heating of the main tape-meter by the heating rollers.
    [0004] The invention also relates to a deployable structure comprising a main tape measure extending in the deployed position along an axis X and having two ends, a secondary tape measure 5 having two ends and a winding mandrel carried by a shaft along an axis Z perpendicular to the axis X, the main tape measure being wound around the mandrel, a first end of the main tape measure being fixed on the mandrel, characterized in that a first end of the tape measure The secondary end is attached at a distance from the first end of the main tape-measure, and a second end of the secondary tape-measure is attached to the chuck at a point distinct from the point of the first end of the main tape-measure. Advantageously, the deployable structure comprises at least two rollers mounted facing each other at the periphery of the mandrel, the rollers being in contact with the main measuring tape, the rollers and the shaft being fixed, the mandrel having a degree of freedom in rotation about the Z axis, the rollers being able to guide the main tape-meters.
    [0005] Advantageously, the rollers are heating rollers. The invention will be better understood and other advantages will become apparent upon reading the detailed description of an exemplary embodiment, which is illustrated by the accompanying drawing in which: Figure 1 illustrates with three diagrams , in section in a plane perpendicular to the Z axis, the deployment of a main tape measure according to the invention, - Figure 2 shows a first variant of the deployable structure of two tape-meters in semi-deployed configuration and FIG. 3 shows a second variant of the deployable structure of two ribbon meters in a semi-deployed and deployed configuration according to the invention, FIG. 4 represents a third variant of the deployable structure. of two ribbon meters in a half-deployed and deployed configuration according to the invention; FIG. 5 represents the buckling of the secondary tape measure 5 to obtain the re-winding of the meter; main ribbon, - Figure 6 shows another variant of the deployable structure of two ribbon meters in half-deployed and deployed configuration according to the invention, - Figure 7 shows the steps of the retractable embedding method of the invention . For the sake of clarity, the same elements will bear the same references in the different figures.
    [0006] Figure 1 illustrates with three diagrams, in section in a plane perpendicular to a Z axis, a deployable structure 10 with a main tape measure 11 according to the invention. The structure 10 comprises the main tape measure 11 extending in an extended position along an X axis and has two ends 81, 82. The structure 10 comprises a secondary tape measure 61 which has two ends 71, 72. The deployable structure 10 also comprises a winding mandrel 13 which is carried by a shaft 14 along the axis Z perpendicular to the axis X. The main tape measure 11 is wound around the mandrel 13. A first end 82 of the tape measure 25 main device 11 is fixed on the mandrel 13. According to the invention, the retractable embedding method comprises the following steps: - Attaching a first end 71 of the secondary tape measure 61 away from a second end 81 of the meter. main tape 11, - Attaching a second end 72 of the secondary tape measure 61 to the mandrel 13 at a point distinct from the point of the first end 82 of the main tape measure 11. An arrow 5 indicates the direction of rotation of the tape. Mandrel 13. In Figure 1a, arrow 5 rotates clockwise. The main tape measure 35 11 is wrapped around the mandrel 13 and a portion of the main tape measure 3024227 including the end 81 is extended parallel to the unfolded axis X. In Fig. 1b, the mandrel 13 has made a rotation about the Z axis clockwise as indicated by the arrow 5. The main tape measure 11 extends further along the X axis. The secondary tape measure 61 remains wound 5, both ends 71, 72 being fixed respectively at the end 81 of the main tape measure 11 and the mandrel 13. In Figure 1c, the main tape measure 11 is fully deployed. The secondary tape measure 61 is also in the deployed position and forms a triangulated structure with the main tape measure 11 and the mandrel 13. The triangulated structure thus obtained constitutes a strut, ensures good maintenance of the main tape measure 11 and gives it good rigidity. FIG. 2 shows a first variant of a deployable structure 100 comprising two ribbon meters in a half-deployed and deployed configuration according to the invention. All the elements of the deployable structure 100 of FIG. 2 are identical to the elements of the deployable structure 10 of FIG. 1. In addition, the deployable structure comprises a second main tape measure 111 which has an axis of deployment and folding substantially. parallel to the unfolded axis X, and extends in the opposite direction to the direction of deployment of the first main tape measure 11. The second main tape measure 111 has two ends 181, 182. The deployable structure 100 includes a second secondary tape measure 161 which has two ends 171, 172. The second main tape measure 111 is also wrapped around the mandrel 13. As for the first main tape measure 11, a first end 182 of the main tape measure 111 is fixed on the mandrel 13. And, like the first secondary tape-measure 61, the second secondary tape-measure 161 is wound, its two ends 17 1, 172 being attached respectively to the end 181 of the main tape measure 111 and mandrel 13. The presence of two main tape-meters allows to deploy a flexible structure of larger area while maintaining good support and good rigidity of the deployable structure. FIG. 3 shows a second variant of a deployable structure of two ribbon meters in a half-deployed and deployed configuration according to the invention. All the elements of FIG. 3 are identical to the elements of FIG. 2. In FIG. 3, contrary to FIG. 2, there is no mention of secondary tape-meters but secondary struts, since it is no longer a question of of tape-meters strictly speaking.
    [0007] Nevertheless, the struts considered contribute in the same way to forming a triangular structure constituted by a strut. In Figure 3, the two secondary struts are flat blades. A flat blade in the deployed configuration provides good tensile strength, but offers no compressive strength. In the deployed position, the blade 61 greatly improves the stiffness of the assembly in the lower stiffness direction of the tape measure (counterclockwise torque around Y). The opposing blade 161 greatly improves the stiffness of the assembly in the least opposite opposite stiffness direction of the tape measure (clockwise torque around Y).
    [0008] On the other hand, it offers better storage capacity than a tape measure since a very small section is generally sufficient to take up the tensile loads. In order to save space in the stored position, and to facilitate the winding, it may therefore be envisaged to use cables, flat blades or flexible strips to replace the tape measures. However, they work only in traction. It is therefore necessary that they work in pairs and are put in opposition using the stiffness of the main tape measure. In fact, when a torque is applied to the main tape measure, a flexible band retains the force, if a torque is applied in the other direction, the opposite flexible band acts. The secondary tape-yards constitute a triangulation system on the tape measure 11. FIG. 4 shows a third variant of a deployable structure of two tape-meters in a stored, semi-deployed and deployed configuration according to the invention. All the elements of Figure 4 are identical to the elements of Figure 2. In Figure 4, the first end 82 of the main tape measure 11 is fixed to the center of the mandrel 13. Similarly, the first end 182 of the tape measure The first two sub-strips 61, 161 are wound, their two ends 71, 72 and 171, 172 respectively being fastened to the end 81, respectively 181 of the main tape-meters. and 111 and the mandrel 13. As explained above, the presence of two main tape-meters allows to deploy a flexible structure of larger area 5 while maintaining a good maintenance and good rigidity of the deployable structure with the two legs of force . In addition, this configuration, in addition to providing a large flexible structural surface in the deployed position, has the advantage of not being bulky in the stored position. Furthermore, as the main tape-meters 11, 111 are wound around the mandrel 13 and fixed at its center, there is a high stability of the assembly and a high stiffness to the embedment. In addition, the mandrel 13 is not positioned at the end of the structure once the main tape-meters 11, 111 unwound. This characteristic plays an important role in the rigidity of the structure. We can note, however, that FIG. 4 represents two main tape measures 11 and 111, but the invention also applies to the case with a single main tape measure fixed to the mandrel between its two ends. FIG. 5 shows the buckling of the secondary tape measure 61 to obtain re-winding of the main tape measure 11. The main tape measure 11 comprises two faces 15, 16. The first end 71 of the secondary tape measure 61 is fixed on a first face 16 of the second end 81 of the main tape measure 11. The folding of the strut composed by the tape measure 61 can be achieved by buckling thereof.
    [0009] Buckling can be achieved by applying a force to the center of the secondary tape and normal to it. By doing so, the secondary tape measure 61 flames, that is to say, it no longer forms a triangulated structure with the main tape measure 11 and the mandrel 13. The portion of the secondary tape measure 61 located between both ends 71 and 72 get closer to the mandrel and tend to rewind. The buckling thus initiated allows the winding of the structure. Due to the attachment of the end 71 of the secondary tape measure 61 to the end 81 of the main tape measure 11, the main tape measure 11 is no longer in its fully extended position. He can then rewind.
    [0010] The force applied perpendicular to the main axis of the main tape measure 61 may be a force applied manually or by motorization. Generally, in actual use, the deployable structure 10 is used for only one deployment. Nevertheless, new mission needs appear. Including the transfer or towing of satellite from a low orbit to a high orbit. During the docking, to control the transfer vehicle, it takes the least possible inertia, that is to say that the presence of deployable structures of large dimensions is not favorable. We must also avoid any interference with satellites that we seek to dock. As a result, it is preferable to wind up the deployable structures. When the satellite is hooked, we can deploy the structure again.
    [0011] An alternative to applying a force to the main tape measure 11 is also shown in FIG. 5. In FIG. 5, a part 25 is positioned on the mandrel 13. The part 25 is rotatable about the axis Z. To this piece 25 is fixed a blade or a flexible cable 26, connecting the piece 25 to the secondary tape measure 61. A rotation of the piece 25 in the direction corresponding to the direction of folding of the main tape measure , moves the secondary tape measure 61 to the mandrel 13 and thus initiates buckling. The piece 25 then abuts on the mandrel 13 and thus drives the latter, allowing the winding of the main measuring tape 11, the secondary tape measure 61 no longer forming a triangulated structure with the main tape measure 11 and the mandrel 13. As explained above, the portion of the secondary tape measure 61 located between the two ends 71 and 72 approaches the mandrel and tends to rewind. Due to the attachment of the end 71 of the secondary tape measure 61 to the end 81 of the main tape measure 11, the main tape measure 11 is no longer in its fully deployed position. He can then rewind. FIG. 6 represents another variant of two ribbon meters of a deployable structure 300 in a semi-deployed and deployed configuration according to the invention. All the elements of FIG. 6 are identical to the elements of FIG. 4. In FIG. 6, the deployable structure 300 further comprises at least two rollers 20, 21 mounted facing the periphery of the mandrel. 13. The rollers 20, 21 are in contact with the tape measures 11, 111. The rollers 20, 21 and the shaft 14 are fixed, the mandrel 13 has a degree of freedom in rotation about the Z axis The rollers 20, 21 are able to guide the main tape-meters. The rollers 20, 21 provide a guiding function for the tape measures 11, 111. The two rollers 20, 21 make it possible in particular to ensure a correct winding of the tape measures 11, 111 around the mandrel 13 during a folding phase and allow to be able to fold the tape measure in flight, for example when the flexible structure is mounted on a satellite. To regulate the deployment of the tape-meters, it is possible to heat the mandrel 13. Advantageously, the rollers 20, 21 may be heating rollers. The heating rollers make it possible to locally heat at two points, advantageously diametrically opposite, the tape measures, thus causing their deployment and also the rotation of the mandrel 13 which can therefore heat the tape measure section then brought into contact with the rollers 20. 21, as shown diagrammatically in FIG. 6b, the arrows indicating the rotation around the Z axis. The local heating by the heating rollers makes it possible to obtain a regulated deployment of the structure. Moreover, since the heating is local, this configuration is energetically economical since it is not necessary to heat the whole of the tape measure and / or mandrel. This feature is particularly interesting for use on satellite.
    [0012] Figure 7 shows the steps of the retractable embedding method according to the invention. The method comprises the following steps: - Point fixing of the second end 81 of the main tape measure 11, step 401 5 - Fixing the first end 71 of the secondary tape measure 61 at a distance from a first end 82 of the tape measure main step 11, step 402 - Attaching a second end 72 of the secondary tape measure 61 to the mandrel 13, step 403 10 - Simultaneous deployment of the main tape measure substantially parallel to the X axis and the secondary tape measure, step 404 - Formation of a triangulated structure between the main tape measure, the secondary tape measure and the chuck, step 405.
    [0013] One can also note the simplicity of assembly as well as a control and reproducibility of the torque during the deployment and folding of the tape-meters. The invention can be applied to hybrid tape meters, consisting of a first driving structure (eg carbon fiber) which allows the deployment of the tape measure, and a thermoelastic regulating part which promotes or limits the deployment according to the temperature applied to it. Using a natural viscosity change phenomenon of a thermoplastic material (or a material having a transformation temperature substantially lower than the engine ribbon material processing temperature) by the temperature ensures good reliability and reproducibility of the deployment. . The invention has a simplicity of assembly, with few parts to assemble. The progress of the measuring tape is well controlled. In fact, the tape measure can be guided by the rollers 20, 21, and locally heated in the case where the rollers 20, 21 are heated, thereby regulating its deployment. Finally, the stacking is autonomous because it is obtained by the bi-stability of the hybrid tape measure with its two stable positions (wound and deployed).
