- Referring now to
FIGS. 1 and 2 collectively, an examplerecreational disk 100 is illustrated. Thedisk 100 comprises adisk body 102 having a substantially planarupper surface 104 and a substantially planarlower surface 106. Askirt 108 extends around an outer peripheral edge of thedisk body 102. In some embodiments, theskirt 108 can comprise a curved sidewall that smoothly transitions into thedisk body 102 so as to not create drag and/or reduce lift when thedisk 100 is thrown. In other embodiments, theskirt 108 extends downwardly from the outer peripheral edge of thedisk body 102. - The
disk 100 can be manufactured from any number of suitable materials that would be known to one of ordinary skill in the art with the present disclosure before them. - The
disk 100 comprises a first plurality of radially arranged blades 110 that are arranged around ahub 112. Thehub 112 can be rotatably coupled with ashaft 114 that is fixed to thedisk body 102. To be sure, the first plurality of radially arranged blades 110 mounted to thehub 112 can freely rotate around theshaft 114 independently from rotation of thedisk body 102 itself. In some embodiments, the first plurality of radially arranged blades 110 are directly or indirectly mounted to theshaft 114. Theshaft 114 is rotatably supported at a central axis A of thedisk 100, according to some embodiments. - In one embodiment, the blades 110 extend away from the
hub 112. The blades 110 each have a cross-section and size that varies according to performance and/or design requirements, such as how much additional lift is required or desired (other embodiments can reduce lift as explained herein). When arranged onto thehub 112, the blades 110 comprise cambering and/or twisting that produce a right-handed effect or a left-handed effect. That is, the arrangement of the blades 110 onto thehub 112 will cause the first plurality of radially arranged blades 110 to rotate either clockwise or counterclockwise during flight, based on their right-handedness or left-handedness. - When the blades 110 are arranged in such a way that they spin in a direction that is opposite to a spin direction of the
disk body 102, the blades 110 will reduce lift produced by thedisk 100. Conversely, when the blades 110 are arranged in such a way that they spin in a direction that is equal to a spin direction of thedisk body 102, the blades 110 will increase lift forces on thedisk 100. - In some embodiments, rather than being rotatably supported, the blades 110 can be held in a fixed position such that the
hub 112 cannot rotate relative to theshaft 114. - In use, when the
disk 100 is rotated and thrown by a user, the first plurality of radially arranged blades 110 will rotate during flight so as to change at least one aerodynamic behavior of thedisk 100. This change in aerodynamic behavior is determined in relation to thedisk 100 without the first plurality of radially arranged blades 110. - The blades 110 can include additional or fewer blades than those illustrated in the drawings. Additionally, the blades 110 can be manufactured from the same materials used to construct other portions of the
disk 100 or different materials. -
FIG. 3 is a perspective view of another examplerecreational disk 200 that comprises adisk body 202 that is constructed similarly to thedisk body 102 ofFIGS. 1 and 2 . Thedisk 200 comprises a first plurality of radially arrangedblades 204 that are disposed below alower surface 206 of thedisk body 202. The first plurality of radially arrangedblades 204 are coupled to (or integrated with) ahub 208 that is rotatably supported on thedisk body 202 by ashaft 210 that is similar to theshaft 114 ofFIGS. 1 and 2 . -
FIGS. 4 and 5 collectively illustrate another examplerecreational disk 300 that comprises two sets of radially arranged blades. By way of example, therecreational disk 300 comprises adisk body 302 that is constructed similarly to thedisk body 102 ofFIGS. 1 and 2 . A first set of radially arrangedblades 304 are disposed above anupper surface 306 of thedisk body 302, while a second set of radially arrangedblades 308 are disposed below alower surface 310 of thedisk body 302. Each of the sets of radially arrangedblades disk body 302. For example, the first set of radially arrangedblades 304 can be associated with a hub and shaft arrangement, as described above with respect toFIGS. 1 and 2 . The sets of radially arrangedblades shaft 312. Abearing 314 is disposed on theshaft 312, between theshaft 312 and thedisk body 302. The bearing provides independent rotatable movement of theshaft 312 relative to thedisk body 302. In some embodiments, the second set of radially arrangedblades 308 are spaced apart from thelower surface 310 of thedisk body 302. This separation between the second set of radially arrangedblades 308 and thelower surface 310 of thedisk body 302 allows the second set of radially arrangedblades 308 to be disposed below a lower terminal edge of askirt 316, allowing for air to contact the second set of radially arrangedblades 306 when thedisk 300 is thrown through the air. - As mentioned above, the blades of both the first of radially arranged
blades 304 and the second set of radially arrangedblades 308 have specific geometries that affect the amount of lift produced thereby. In some embodiments, the shape, size, number, and otherwise arrangement of blades on each of the sets of radially arrangedblades blades blades 304 comprise a first configuration (e.g., cambering, twisting, angle of attack, and cross sectional size along chord length) and the blades of the second set of radially arrangedblades 308 comprise a second configuration. The first and second configurations can be different from one another. In one embodiment, the first set of radially arrangedblades 304 have an overall diameter D1 and the second set of radially arrangedblades 308 have an overall diameter D2. In some embodiments, the diameter D1 is greater than the diameter D2, although these diameters can be equal to one another. In other embodiments, the diameter D2 is greater than the diameter D1. -
FIG. 6 illustrates another examplerecreational disk 400 that comprises askirt 402 that includes a plurality of vent holes such asvent hole 406. The vent holes allow air to enter inside theskirt 402 so as to contact and rotate a first set of radially arrangedblades 404. That is, during flight, air passes through the plurality of air vents to rotate the first set of radially arrangedblades 404. -
