         3 . The recreational disk according to  claim 2 , further comprising a second plurality of radially arranged blades that are located on the shaft on an opposing side of the disk relative to the first plurality of radially arranged blades. 
     
     
         4 . The recreational disk according to  claim 1 , wherein the disk comprises a skirt that extends downwardly from an outer peripheral edge of the disk. 
     
     
         5 . The recreational disk according to  claim 4 , wherein the skirt comprises a plurality of air vents, further wherein during flight, air passes through the plurality of air vents to rotate the first plurality of radially arranged blades, the first plurality of radially arranged blades being disposed below the lower surface of the disk. 
     
     
         6 . The recreational disk according to  claim 1 , wherein the disk comprises a central aperture that is defined by an inner sidewall, further wherein the first plurality of radially arranged blades extend from the inner sidewall into the central aperture. 
     
     
         7 . The recreational disk according to  claim 6 , wherein each of the first plurality of radially arranged blades comprises a blade body, further wherein a terminal end of blade body has a length that is greater than a length of an opposing end of the blade body that couples with the inner sidewall. 
     
     
         8 . The recreational disk according to  claim 7 , wherein a portion of the blade body extends above the upper surface of the disk and below the lower surface of the disk. 
     
     
         9 . The recreational disk according to  claim 8 , wherein the blade body of the first plurality of radially arranged blades are any of cambered and twisted. 
     
     
         10 . The recreational disk according to  claim 1 , further comprising an annular ring mounted to the disk and in alignment with the central aperture, wherein the first plurality of radially arranged blades are disposed within the annular ring. 
     
     
         11 . The recreational disk according to  claim 1 , further comprising a second plurality of radially arranged blades that are rotatably coupled to an opposing side of the disk relative to the first plurality of radially arranged blades. 
     
     
         12 . The recreational disk according to  claim 1 , wherein the first plurality of radially arranged blades are mounted on a rotatable shaft and the first plurality of radially arranged blades are mounted on a second rotatable shaft. 
     
     
         13 . The recreational disk according to  claim 1 , wherein the first plurality of radially arranged blades change the at least one aerodynamic behavior of the disk by producing lift in a direction that is perpendicular to a flight path that is coplanar with the disk. 
     
     
         14 . A recreational disk, comprising:
 a disk comprising an upper surface, a lower surface, and a central aperture defined by an inner sidewall; and   a first plurality of blades extending radially from the inner sidewall into the central aperture to form a second aperture, the first plurality of blades producing lift in a direction that is perpendicular to a flight path that is coplanar with the disk when the disk rotates during flight.   
     
     
         15 . The recreational disk according to  claim 14 , wherein each of the first plurality of radially arranged blades comprises a blade body, further wherein a terminal end of the blade body has a length that is greater than a length of an opposing end of the blade body that couples with the inner sidewall. 
     
     
         16 . The recreational disk according to  claim 15 , wherein a portion of the blade body extends above the upper surface of the disk and below the lower surface of the disk. 
     
     
         17 . The recreational disk according to  claim 16 , wherein the blade body of the first plurality of radially arranged blades are any of cambered and twisted. 
     
     
         18 . The recreational disk according to  claim 17 , further comprising an outer rim formed by a protrusion that extends circumferentially around an outer edge of the disk. 
     
     
         19 . A recreational disk, comprising:
 a disk comprising an upper surface, a lower surface, and a central aperture defined by an inner sidewall;   a first plurality of radially arranged blades rotatably supported on any of the upper surface and the lower surface of the disk, the first plurality of radially arranged blades rotating during flight as the disk spins so as to be a first source of additional lift for the spinning disk; and   a second plurality of radially arranged blades rotatably supported on an opposing surface relative to the first plurality of radially arranged blades, the second plurality of radially arranged blades rotating during flight as the disk spins so as to be a second source of additional lift for the spinning disk.
