DETAILED DESCRIPTION

[0030] Referring to FIG. 1 an ARS 100 in accordance with an embodiment of the present disclosure is shown in its initial position for calibrating electronic positioning components mounted to a ducted fan 102. As shown, the ducted fan 102 is an air moving arrangement comprising a mechanical fan 104 (also termed a propeller) mounted within a cylindrical shroud 106 (also termed a duct). The ARS 100 surrounds and is mounted to the shroud 106 of the ducted fan 102.

[0031] Referring to FIG. 2, an ARS 100 is shown alone (without the accompanying ducted fan 102 propulsion device).

[0032] FIG. 3 depicts an exploded view of the ARS 100 of FIG. 1 with the housing 29 omitted so as to better view the other elements. As shown, a transmission belt 40a surrounds the top rim 32a and passes between the top gear 35a and a pair of pretensioner rollers 36. A second transmission belt 40b surrounds the bottom rim 32b and passes between the bottom gear 35b and a pair of pretensioner rollers 36. Screws or bolts 304 each pass through a respective opening in the top rim 32a or bottom rim 32b, which optionally feature extrusions 1002 adapted to receive the screw or bolt 304 and support a bearing 202. Each screw or bolt 304 rotatably supports a bearing 202 and is secured to a nut 306.

[0033] The bearings 202 permit the top rim 32a and bottom rim 32b to each independently rotate with respect to the housing 29. The bearings 202 rest against the inner surface of the housing 29 and move freely across that surface.

[0034] Wire cables 108 pass through housing 29 such that the enclosures 30 are operatively connected to the wire cables 108.

[0035] FIG. 4 depicts an exploded view of mounting brackets 402, 404 in accordance with the present disclosure which connect the ARS 100 to a propulsion system, such as ducted fan 102. As will be clear to one of skill in the art, these mounting brackets 402, 404 may be adapted so as to connect the ARS 100 to any ducted fan or cylindrical propulsion system. For example, the size of components 26 and 27 may be selected based on the specific requirements of the propulsion system. A plurality of screws 406 or other connective elements are used to secure components of the mounting brackets 402, 404 together.

[0036] FIG. 5 depicts an embodiment of an ARS 100 with an integrated ducted fan 102, showing the ducted fan 102 pitched forward. The inclination of the ducted fan 102 is accomplished through the opposite rotation of the top rim 32a and bottom rim 32b.

[0037] FIG. 6 depicts an embodiment of an ARS with integrated ducted fan, whereby arrows demonstrate the rotation process on the vertical axis to the component 29 due to the unidirectional rotation of the components 32a and 32b.

[0038] Referring to FIG. 7, through the arrows, the kinematic process of changing the angle of an ARS100 to allow for a vertical inclination is shown.

[0039] FIG. 8, through the arrows, details the one-way circular rotation of the ARS that allows a 360° horizontal rotation.

[0040] Embodiments may combine both working processes described above regarding rotation around the vertical axis and the horizontal axis together at different angles.

[0041] In order to better understand the working process described above, the following discussion decomposes the components shown in FIGS. 1-8. Specifically, embodiments of an ARS consistent with the present disclosure comprise a disc 29, with a revolving profile, which contains a channel for arranging the two wire cables 108 and their outputs. At the same time, the component 29, on the perimeter, has equidistant radially spaced clamping elements 204 that serve as a fixing zone to connect the ARS 100 to the wing or fuselage of an aircraft or other vehicle. Also, in the inner surface of housing 29 is provided with a pair of tracks for the movement of bearings 202; the bearings 202 affixed to the top rim 32a move along a top track while the bearings 202 affixed to the bottom rim 32b move about the bottom track.

[0042] In FIGS. 1-3 and 5-8, top rims 32a and 32b, which are discs, are illustrated, and on the outside of which are radially distributed coupling teeth and a clamping attachment for a lever 34a and 34b, and the revolving of which is described by the profile of a cornice with two non-parallel sides. On the interior of the rims 32a and 32b are located radially distributed extrusions, which serve to fix the bearings 202 which assures the rotation and fixation of the discs 32a and 32b on the tracks of component 29. Conceptually, rims 32a and 32b, in connection with housing 29, have a functioning principle and similar to that of a “Radial Bearing.”

[0043] In FIGS. 1-3, 5-9, transmission belts 40a and 40b are illustrated which comprise evenly spaced teeth distributed along the length of the transmission link between the discs 32a and 32b with the gear wheels 35a and 35b which are rigidly fixed on the axis of the motors 33a and 33b. But the components 36 provide an optimal belt tensioning 40a and 40b.

[0044] Referring to FIGS. 2, 7, 8, and 9, two chassis 30 are distinguished, which are rolled by bearings 202 (also termed “angular contact bearings”) on tracks on the inner surface of housing 29. In the chassis 30 is mounted an angular contact bearing, in which is mounted a component 31, on one side with a single component 41; on the other hand, the component 28 only fastens with the component 31.

[0045] The singular element 41, rigidly fixed to the component 28, which articulates by the levers 34a and 34b with the discs 32a and 32b, provides rotation and/or angle inclination to the horizontal plane of any ducted fan mounted within the ARS 360°. The component 28 is fixed in a series of conceptually variable elements 26 and 27 in FIG. 4, which serve to fix any ducted fans with the 360° ARS.

[0046] As shown, the ARS 360° device, in addition to being a rigid suspension for any build-in ducted fans in its passive state, is working on three distinctive scenarios.

[0047] First, changing the angle vertical positioning of the integrated ducted fan or any propulsion system, due to the opposite rotation of the independent motors 33a and 33b; coupled to toothed wheels 35a and 35b; connected with discs 32a and 32b; through belts 40a and 40b; moving the levers 34a and 34b which slopes elementally 41, obtaining a vertical rotation of the ducted fan propulsion system.

[0048] Second, changing the angle of horizontal positioning, due to the unison movement of all elements: 33a and 33b; 35a and 35b; 40a and 40b; and 41.

[0049] Third, a variable combination of scenarios 1 and 2.

[0050] In an embodiment, an ARS 360° in accordance with the present disclosure comprises a disc with a revolving profile that serves the base of consecutive mounting of all the construction elements of the device. The disk in its profile contains a cable channel for arranging and outputting two wires. At the same time, the disc on the perimeter has radially spaced equidistant clamping elements of the 360° ARS body, which serves to fix it on the wings or fuselage of any flying apparatus. Also, the profile of the disc has tracks for the movement of the bearings.

[0051] In an embodiment, an ARS 360° further comprises two discs, on the outside of which are radially distributed coupling teeth. A clamp for the joint of a lever; revolving is described by the profile of a cornice with two non-parallel sides; on the inside of the discs we find radially a few extrusions with the function of fixing the bearings for rotation and fixing them to the base plate tracks.

[0052] In an embodiment, an ARS 360° further comprises two existing standardized belts as part of the 360° ARS assembly; two toothed wheels with the tooth profile adapted to the coupling transmission belt; two existing reduction gears, standardized for the 360° ARS assembly; two chassis with rigid/semi rigid bearings; a geometric center with a cassette for mounting an angular bearing; two bushings with sharpened axes, strapped by a channel which on one side branches into three access channels; a two-arm crank specially fitted with articulated mounting areas and having a slit hole in the geometric middle; a slitted bush from the inside; and a bearing mounting area on the outside.

[0053] Each of the mentioned components is designed to be scalable and easily adapted to any required size. They could be made in varying proportions of light alloys, composite materials, rigid and flexible polymers.

[0054] Each of these embodiments and any obvious variation thereof is contemplated as falling within the spirit and scope of the claimed invention, which is set forth in the following claims. Moreover, the present concepts expressly include any and all combinations and sub-combinations of the preceding elements and aspects. The present disclosure is not limited to the specific illustrated example but extends to alternative embodiments and other shapes and/or configurations in accordance with the knowledge of one of ordinary skill in the art applied consistent with the presently disclosed principles.
