DETAILED DESCRIPTION OF SOME EMBODIMENTS

(6) Some embodiments will now be described with reference to the Figures.

(7) Referring now to FIGS. 1 to 3, a storage and transportation container 1 for a radome 2 is illustrated for an aircraft 4. As indicated above, the storage and transportation container 1 is to be positioned and carried within a cargo hold 6 of the aircraft 4.

(8) Throughout the disclosure, it will be assumed that the container 1 in the cargo hold 6 is standing on a horizontal ground and that any plane parallel to the ground is horizontal, and any plane at right angles to the ground is vertical. That is, as shown in FIG. 1, the aircraft is shown positioned relative to the ground, which is considered to be horizontal relative to the ground.

(9) The free space of the cargo hold 6 in most commercial airplanes of known type like that of the cargo hold of, for example, Airbus A320 aircraft is delimited by a base horizontal floor 8, a ceiling 10 parallel to the base horizontal floor 8 of the cargo hold 6 corresponding to the floor 12 of the cabin 14, and two walls 16, 18 longitudinal to the aircraft 4. Each wall 16, 18 includes two parts, a vertical first part 16a, 18a extending from the ceiling 10 proximate to the fuselage 20 of the aircraft 4, and a second part 16b, 18b comprising two successive planar flats (16b, 16b), (18b, 18b) that are inclined relative to the vertical extending from the first part 16a, 18a to the floor 8 of the cargo hold 6 in such a way as to follow the curved outline of the fuselage 20 at the bottom of the cargo hold 6. The planar flats 16b, 16b on one side, and the planar flats 18b, 18b on the opposing side are chamfered and inclined to substantially conform to the shape of the aircraft fuselage.

(10) Referring now to FIG. 2, the radome 2 is illustrated. The radome 2 includes a panel 22 made of material permeable to electromagnetic waves and, for example, made of composite material. The panel 22 has a dual curvature so as to form a concavity having a dome-shaped form and configuration. The free peripheral edge 24 of the radome 2 is joined, generally in an articulated manner, by any type of known means and for example by a hinge system 26, to the rest of the fuselage 20 of the aircraft. In the following description, it is considered that the radome 2 has been dismantled and removed from the aircraft as shown in FIGS. 1 to 3.

(11) The panel 22 has an inner face 28 and an outer face 30. The inner face 28 of the panel 22 is hollow. In the forms illustrated in FIGS. 1 to 3, the free peripheral edge 24 or at least a part of the edge lies in a plane P, shown in FIG. 1. As a result of this, the radome 2 can rest against a planar surface of the inner face 28 and, in particular on the ground, with its peripheral edge or the part lying in the plane P thereof, which as will be explained in greater detail, does not extend beyond the peripheral edge of the top wall.

(12) The radome 2 may also comprise other components such as, but not limited to, lightning protection strips 32.

(13) The container 1 for a radome 2 comprises a top wall 34 and a bottom wall 36 that are planar and parallel to one another. The container also includes a peripheral wall 38, bounding an enclosure surrounding the radome 2 and allowing the protection and transportation thereof. The top wall 34 is planar and configured to be positioned parallel to and facing the ceiling 10 of the cargo hold 6. The bottom wall 36 is also planar and is configured to rest on the floor 8 of the cargo hold 6. Thus, the flatness and the parallel configuration of the top 34 and bottom 36 walls of the container 1 make it possible to optimize the possible internal volume of the container 1.

(14) Contrary to the existing containers, the container 1 according to an exemplary embodiment has a geometry matched to a radome arranged vertically inverted inside the container. In other words, the nose 40 of the radome points downwards which means that the free peripheral edge 24 of the radome is located on the side of the top wall 34 of the container.

(15) The top wall 34 has a closed curved outline and a surface of a dimension greater than that of the bottom wall 36. The bottom wall may have an outline forming a parallelogram. The form of the top wall 34 is matched to the form of the free peripheral edge 24 of the radome 2. According to an embodiment that is illustrated, the peripheral edge 24 of the top wall 34 is parallel to the free peripheral edge 24 of the radome 2. This will allow the bulk of the top wall 34 of the container to be optimized by being located as close as possible to the radome 2 arranged inside. The outline in parallelogram form of the bottom wall 36 of the container 1 contrasts with the curved outline of the top wall 34. This will allow for a stable base on which the container 1 rests. In addition, the dimensions of the surface of the bottom wall 36 being smaller than those of the top wall 34, the container 1 follows the form of the radome 2 arranged inverted inside the container 1 while best matching the particular geometry of the cargo hold 6.

(16) As illustrated in FIGS. 2 and 3, the container 1 comprises a double peripheral wall 38, an inner wall 38a having a dome-shaped configuration and form, and an outer wall 38b at least partially inclined inwards relative to the vertical from the top wall 34 to the bottom wall 36. The inner wall 38a has a dome-shaped configuration and form to substantially conform to the dome-shaped configuration and form of the radome 2. According to the embodiment illustrated, the form of the inner wall 38a corresponds to the dome-shaped configuration of the radome 2. Thus, there is no need to provide specific means for fixing the radome 2 inside the container 1. The radome 2 rests inside, in which the outer surface of the radome contacts the inner wall 38a, thereby preventing it to move around. It is held by the corresponding form of the inner wall 38a.

(17) The outer wall 38b makes it possible to link the form of the closed curved outline of the top wall 34 of the container to the parallelogram form of the bottom wall 36 to enclose the inner wall 38a in which the radome 2 is held. The outer peripheral wall 38b, by virtue of its inward inclination, follows the form with the vertically decreasing dimensions of the inner wall 38a of the container and of the longitudinal walls 16, 18 of the hold. Thus, the geometry of the container 1 is optimized relative to that of the cargo hold 6.

(18) Referring more specifically to FIG. 3, the top wall 34 may be removable to form a cover. This will allow for easy removal of the top wall 34 without risking damaging the radome 2. The top wall 34 of the container has a vertical flange 42 at a peripheral edge thereof. The peripheral wall 38 of the container has a vertical top end edge 44 having a shape and dimension corresponding to the vertical flange 42 of the top wall 34. The dimensions of the flange 42 of the top wall 34 relative to the top end edge 44 of the peripheral wall are such that the vertical flange 42 of the top wall encircles the edge 44 of the peripheral wall 38. The flange 42 of the top wall 34 thus makes it possible to align the top wall 34 relative to the peripheral wall 38 and hold the cover on the container 1. Fixing means of any known type can be provided to secure the top wall 34 to the peripheral wall 38.

(19) According to the embodiment illustrated in FIGS. 2 and 3, the bottom wall 36 of the container has a rectangular form and thus substantially matches the geometry of the base horizontal floor 8 of the cargo hold 6. It is contemplated that other shapes and configurations, such as a square, are within the scope of the disclosure.

(20) Still according to the embodiment illustrated in FIGS. 2 and 3, the top wall 34 of the container 1 may be circular and having a disc shaped form having a circular peripheral edge matched with the free peripheral circular edge 24 of radome 2.

(21) Moreover, as seen in the embodiment illustrated in FIGS. 2 and 3, the peripheral wall 38 may include four panels, only two 38 and 38 of which are shown in FIG. 3. The bottom edge 48 of each of these panels is rectilinear whereas the top edge 50 is curved, which gives each panel a specific geometry and shape as shown.

(22) Furthermore, in the embodiment illustrated in FIGS. 2 and 3, the container comprises a parallelepiped base 52, which may be integrally formed, the outline of the top face of which consists of the bottom edges 48 of the panels of the peripheral wall 38 and the bottom face of which forms the bottom wall 36 of the container 1. The base 52 allows lifting and moving by a forklift, but remains of a height much lower than the raising block required in the prior art because its function is not to raise the container.

(23) Given the form of the container 2 to substantially conform to the shape and configuration of the cargo hold 6, the raising of the container 1 is not necessary. The top face of the base 52 substantially conforms to the bottom edges 48 of the corresponding peripheral wall on each side, and the bottom face of the base conforms to the bottom wall 36 of the container 1. Moreover, each side of the base 52 may include a cut-out or opening dimensioned to receive the forklift forks to lift and transport the container 1.

(24) While at least one exemplary embodiment of the present invention(s) is disclosed herein, it should be understood that modifications, substitutions and alternatives may be apparent to one of ordinary skill in the art and can be made without departing from the scope of this disclosure. This disclosure is intended to cover any adaptations or variations of the exemplary embodiment(s). In addition, in this disclosure, the terms comprise or comprising do not exclude other elements or steps, the terms a or one do not exclude a plural number, and the term or means either or both. Furthermore, characteristics or steps which have been described may also be used in combination with other characteristics or steps and in any order unless the disclosure or context suggests otherwise. This disclosure hereby incorporates by reference the complete disclosure of any patent or application from which it claims benefit or priority.
