Abstract
Description
- This invention was made with government support under contract number W9089-34082 awarded by the U.S. Department of Defense. The government has certain rights in the invention.
- 1. Field of the Invention
- The present disclosure relates to window assemblies, and more particularly to window assemblies such as those that require specific optical performance for use in applications that can impose stress, such as in the exterior of aircraft, other vehicles, and environmental test chambers.
- 2. Background of the Related Art
- Windows installed on vehicles need to be durable but also meet stringent optical and mechanical requirements depending on the intended application. A traditional window assembly includes a window substrate cemented into a frame using a compliant adhesive, such as a room temperature vulcanizing (RTV) material. The RTV bond provides isolation of the window from environmental loads. The portions of loads that are not absorbed by the RTV bond layer can be transmitted to the window and can cause stress and strain in the window substrate. Stress and strain can alter a window's optical properties. As a result, traditional window assemblies can have variable optical and mechanical performance depending on forces acting on the vehicle housing them.
- Such conventional methods and systems have generally been considered satisfactory for their intended purposes. However, there is still a need in the art for improved window assemblies. The present disclosure provides a solution for this need.
- A flexure ring for a window assembly includes a continuous annular portion and a segmented portion. The continuous annular portion defines a ring axis. The segmented portion defines a plurality of circumferential segments. The continuous annular portion is connected to each circumferential segment by a respective neck. Each neck extends from the continuous annular portion to a respective one of the circumferential segments. The continuous annular portion, the segmented portion and the necks are configured to circumscribe a window pane.
- Each neck can extend from the continuous annular portion in a substantially axial direction with respect to the ring axis, and/or at an angle with respect to the ring axis, e.g. in a cantilevered fashion. The circumferential dimension of each neck can be less than the circumferential dimension of its respective circumferential segment. Each circumferential segment, respective necks and continuous annular portion can have substantially similar inner diameters when in a relaxed state. The radially outer extent of the continuous annular portion can be greater than the radially outer extent of the segmented portion and the necks when in a relaxed state.
- A window assembly includes a window pane and a flexure ring. The window pane has opposed top and bottom surfaces and an outer periphery. The flexure ring defines a ring axis and is mounted to the outer periphery of the window pane for providing the window pane with substantial isolation from vehicle induced loads.
- The window assembly can include an elastomeric material between the outer periphery of the window pane and the flexure ring. Each circumferential segment can have an inner diameter surface and an outer diameter surface. The inner diameter surface can be secured to the window pane. The continuous portion of the flexure ring has an inner diameter surface and an outer diameter surface, wherein the outer diameter surface is secured to a frame. An adhesive layer can be disposed on an inner diameter surface of each circumferential segment. The adhesive layer can be segmented to correspond to each circumferential segment.
- The window assembly can also include an intermediary ring mounted radially between the outer periphery of the window pane and the flexure ring. Each circumferential segment can have an inner diameter surface and an outer diameter surface. The inner diameter surface can be secured to an outer diameter surface of the intermediary ring.
- These and other features of the systems and methods of the subject disclosure will become more readily apparent to those skilled in the art from the following detailed description of the preferred embodiments taken in conjunction with the drawings.
- So that those skilled in the art to which the subject disclosure appertains will readily understand how to make and use the devices and methods of the subject disclosure without undue experimentation, preferred embodiments thereof will be described in detail herein below with reference to certain figures, wherein:
-
FIG. 1 is a perspective view of an exemplary embodiment of a window assembly constructed in accordance with the present disclosure showing the window pane, the flexure ring, the intermediary ring and the frame; -
FIG. 2 is a cross-sectional perspective view of a portion of the window assembly ofFIG. 1 , showing the continuous annular portion and the segmented portion of the flexure ring; -
FIG. 3 is a cross-sectional perspective view of a portion of the window assembly ofFIG. 1 , showing the circumferential segments of the flexure ring with the frame removed; -
FIG. 4 is a perspective view of an exemplary embodiment of a flexure ring constructed in accordance with the present disclosure showing the continuous annular portion and the segmented portion; -
FIG. 5 is a cross-sectional perspective view of a portion of the flexure ring ofFIG. 4 , showing the continuous annular portion, the segmented portion, and the necks; -
FIG. 6 is a cross-sectional perspective view of a portion of another exemplary embodiment of a window assembly constructed in accordance with the present disclosure, showing the continuous annular portion and the segmented portion of the flexure ring; and -
FIG. 7 is a cross-sectional perspective view of a portion of the window assembly ofFIG. 6 , showing the flexure ring secured to the frame. - Reference will now be made to the drawings wherein like reference numerals identify similar structural features or aspects of the subject disclosure. For purposes of explanation and illustration, and not limitation, a perspective view of an exemplary embodiment of a window assembly accordance with the disclosure is shown in
FIG. 1 and is designated generally byreference character 100. The systems and methods described herein can be used in windows for vehicles, or for mirrors, lenses or windows in any other suitable optical instrument, for example, to provide isolation from loads transmitted through the frame while maintaining out-of-plane stiffness. - As shown in
FIG. 1 window assembly 100 includes awindow pane 102, aflexure ring 104, anintermediary ring 106 and aframe 108.Intermediary ring 106 is mounted between the outer periphery ofwindow pane 102 and an inner periphery offlexure ring 104.Flexure ring 104 defines a ring axisA. Window pane 102,flexure ring 104, andintermediary ring 106 are all mounted withinframe 108. Those skilled in the art will readily appreciate thatflexure ring 104 can providewindow pane 102 with substantial isolation from loads transmitted through the frame. It is also contemplated that theflexure ring 104 tends to allow for greater isolation from environmental loads as compared with traditional window assemblies while allowing the continued use of traditional thin RTV bonds or even eliminating the traditional RTV bond entirely. Those skilled in the art will readily appreciate that there can be a trade-off between RTV bonds and out-of-plane stiffness, e.g. a thicker RTV bond tends to provide greater isolation from in-plane loads, but reduced out-of-plane stiffness. - Now with reference to
FIG. 2 ,window pane 102 has opposed top and bottom surfaces, 112 and 114, respectively, and anouter periphery 116.Flexure ring 104 includes a continuousannular portion 118 and a segmentedportion 120. Continuousannular portion 118 defines acircumferential channel 122 separating aninner diameter flange 124 and anouter diameter flange 126.Continuous portion 118 offlexure ring 104 has aninner diameter surface 144 and anouter diameter surface 146.Inner diameter surface 144 is proximate tointermediary ring 106.Outer diameter surface 146 is secured to frame 108 with an adhesive, e.g. an elastomeric material, such as a RTV material. Those skilled in the art will readily appreciate that whileflexure ring 104 is described herein as being affixed to frame 108 using an adhesive, a mechanical fastening method, or any other suitable fastening method can be used. - As shown in
FIG. 3 , anelastomeric material 110, such as a RTV material, is disposed between the outer periphery ofwindow pane 102 andintermediary ring 106.Segmented portion 120 definescircumferential segments 128. Continuousannular portion 118 is connected to eachcircumferential segment 128 by arespective neck 130.Necks 130 extend from theinner diameter flange 124 in a substantially axial direction with respect to ring axis A. It is also contemplated thatnecks 130 can extend frominner diameter flange 124 at an angle with respect to ring axis A, e.g. in a cantilevered fashion in a radially inward and/or outward direction. - With continued reference to
FIG. 3 , continuousannular portion 118,segmented portion 120, andnecks 130 all circumscribeintermediary ring 106, and in turn,window pane 102. Continuousannular portion 118,segmented portion 120, andnecks 130 can be tuned to achieve a desired stiffness in the radial, tangential and hoop directions,e.g. necks 130 andcircumferential segments 128 can be thicker or thinner, longer or shorter, narrower or wider, and/or any other suitable shape depending on what is suitable for a given application and the expected operating conditions ofwindow 102. For example,necks 130, continuousannular portion 118, and/orcircumferential segments 128 can be thicker at the ends and thinner in the middle, and/or thinner on the ends and thicker in the middle. In other words,necks 130, continuousannular portion 118, and/orcircumferential segments 128 can be shaped depending on the desired stiffness/compliance, natural frequency, peak stress, optical distortion ofwindow pane 102, and the like. The individualcircumferential segments 128 and theirrespective necks 130 tend to provide more isolation from in-plane environmental loads without detrimentally increasing out-of-plane compliance (motion). Further, those skilled in the art will readily appreciate that the number ofcircumferential segments 128 making up the segmentedportion 120 can vary depending on the number required for a given application. - As shown in
FIGS. 3 , 4 and 5,circumferential segments 128 have aninner diameter surface 132 and anouter diameter surface 134. Inner diameter surfaces 132 ofcircumferential segments 128 are secured to anouter diameter surface 142 ofintermediary ring 106 with an adhesive 148, such as a RTV material, other fastening means, or the like.Intermediary ring 106 can tend to provide additional attenuation of loads transmitted from the external environment towindow pane 102. In an alternate embodiment,intermediary ring 106 is omitted andinner diameter surface 132 is secured towindow pane 102 with anelastomeric material 110, e.g. a RTV material, or other adhesive or fastening means. Those skilled in the art will also appreciate that while inner diameter surfaces 132 ofcircumferential segments 128 are shown and described herein as being secured to eitherouter diameter surface 142 ofintermediary ring 106 orwindow pane 102 with an adhesive, inner diameter surfaces 132 can be secured with a mechanical fastening method, or any other suitable fastening method. -
Circumferential segments 128 can be sized for optimal stress distribution in the adhesive regions, e.g. betweeninner diameter surface 132 ofcircumferential segments 128 andouter diameter surface 142 ofintermediary ring 106, for example. In other words, the shape and size of eachcircumferential segment 128 dictates the stress distribution in the adhesive layer,e.g. adhesive 148, and also its stiffness. The shape and size ofcircumferential segments 128 can also effect the performance ofwindow assembly 100, as a whole, for example, it can vary the natural frequency, bond strength, and ultimately the optical performance. It is contemplated thatflexure ring 104 can be mounted to frame 108,intermediary ring 106, and/orwindow pane 102 in a strain-free state. Those skilled in the art will readily appreciate that mounting in a strain-free state means, for example, assembling an optomechanical assembly where the critical optical and mechanical reference surfaces are aligned by use fixtures, then a suitable adhesive material, such as RTV or epoxy, is injected between desired mating surfaces while the parts are in a non-strained, or at-rest, condition. - With continued reference to
FIGS. 3 and 4 , anadhesive layer 148, e.g. a RTV material, is disposed on inner diameter surfaces 132 of eachcircumferential segment 128.Adhesive layer 148 can be continuous or segmented as shown, either partially or entirely, to correspond to eachcircumferential segment 128. For example, it is contemplated thatadhesive layer 148 can be continuous alongouter diameter surface 142 ofintermediary ring 106, and/or can be continuous alongouter diameter surface 142 ofintermediary ring 106 but include scores inadhesive layer 148 between each respective circumferential segment to partiallysegment adhesive layer 148. Segmentation ofadhesive layer 148, partially or entirely, tends to provide additional isolation between eachcircumferential segment 128 and provides for an expansion area for a substantially incompressibleadhesive layer 148, e.g. a RTV material, under load conditions. - As shown in
FIG. 5 , a circumferential dimension B of eachneck 130 is smaller than a circumferential dimension C of respectivecircumferential segments 128.Circumferential segments 128,necks 130, and continuousannular portion 118 have substantially similar inner diameters when in a relaxed state. A radially outer extent of continuousannular portion 118 is greater than a radially outer extent ofsegmented portion 120 andnecks 130 when in a relaxed state. Variance between circumferential dimension B and circumferential dimension C can operate to produce compliance in the lateral direction, e.g. in a plane parallel to top and bottom surfaces, 112 and 114, respectively, and in the hoop direction. The thickness offlexure ring 104 andwindow pane 102, in the axial direction with respect to ring axis A, can be substantially the same, tending to provide a compact window assembly design. - With reference now to
FIG. 6 , another embodiment of awindow assembly 200 is shown.Window assembly 200 includes awindow pane 202, anelastomeric material 210, anintermediary ring 206, and aframe 208, similar towindow pane 102,elastomeric material 110,intermediary ring 106 andframe 108, described above.Window assembly 200 includes aflexure ring 204 that includescircumferential segments 228, similar tocircumferential segments 128, described above. Inner diameter surfaces 232 ofcircumferential segments 228 are secured to anouter diameter surface 242 ofintermediary ring 206 with anadhesive layer 248, such as a RTV material, other fastening means, as described above, except thatadhesive layer 248 is in a continuous ring aroundouter diameter surface 242. Although continuous, it is contemplated thatadhesive layer 248 can include scores, indicated schematically by the dashed line, between eachrespective circumferential segment 228 to partially or entirelysegment adhesive layer 248. - As shown in
FIG. 7 ,window assembly 200 includes aflexure ring 204, similar toflexure ring 204 described above, except that a continuousannular portion 218 offlexure ring 204 does not include opposing flanges. Instead, continuousannular portion 218 of flexure ring includes aninner diameter surface 244 and anouter diameter surface 246.Inner diameter surface 244 is proximate to anouter diameter surface 242 ofintermediary ring 206.Outer diameter surface 246 is secured to frame 208 with an adhesive 248, e.g. an elastomeric material, such as a RTV material, described above. - With reference now to
FIGS. 1-7 , loads fromframes respective window panes respective necks circumferential segments necks circumferential segments respective window panes respective necks circumferential segments e.g. necks circumferential segments respective window panes window pane 102. In addition, as described above, use ofintermediary rings elastomeric material 110, can be sized to provide both athermalization and mechanical isolation. In some cases, this can tend to lead to very thick bond layers, e.g.elastomeric material intermediary rings elastomeric material - The methods and systems of the present disclosure, as described above and shown in the drawings, provide for window assemblies with superior properties including improved isolation from vehicle induced loads while maintaining out-of-plane stiffness. While the apparatus and methods of the subject disclosure have been shown and described with reference to preferred embodiments, those skilled in the art will readily appreciate that changes and/or modifications may be made thereto without departing from the spirit and scope of the subject disclosure.
