Definitions

  • This invention relates to kites, its object being a kite so constructed that its lifting power is at least partly due to the so-called Magnus effect.
  • Magnus effect the power created in a direction away from the side of the rarefied air adjacent a revolving cylinder impinged upon by an air current, the speedof which is lower than the circumferential speed of the cylinder, owing to which current the air at one side of the cylinder is rarefied by the frictional effect of the cyljinder, and at the other side is compressed.
  • my novel kite comprises one or more substantially cylindrical bodies each mountedfor rotation about a substantially 'horizontal axis and adapted to be driven by suitable means, preferably by the wind itself.
  • Fig. 1 is a front elevational view of a kite comprising .two substantially cylindrical rotors mounted in a common frame, and I Fig. 2 is a sectional view along the line lI-II in Fig. 1.
  • the kite illustrated comprises two superposed, horizontal, substantially cylindrical, hollow bodies or rotors 3 and 4, closed at both ends by disks 3a, 3b and 4a, lb, respectively. Said bodies are rotatable about shafts 3c and 40, respectively,
  • the uprights are interconnected by a horizontal bar 5c having extensions 50', the ends of which are connected, by wires 51! and 5e respectively, to the ends of the uprights 5a, 5b so as to form a sufficiently rigid structure.
  • diagonal wires 5f and 59 keep the uprights 5a, 5b in fixed relative position.
  • a pendulous tail 5 appended for balancing purposes.
  • the kite can be flown on a long cord or wire I, attached by wires 111, lb to the bar 50.
  • Each of the said substantially cylindrical bodies 3, I is composed of two semi-cylindrical shells 3d, 3e and 4d, 4e, respectively.
  • the shells of each body are radially shifted relative to one another, as clearly shown in Fig. 2, so as to form a small turbine adapted,, when impinged by the wind blowing in the direction of the arrows 8, to rotate in the direction of the arrows 9, the rotary speed of said turbines depending upon the speed of the wind. Owing to.
  • train of two or more kites may be used in a manner well-known in meteorology.
  • the rotors may be used in any desired number, depending upon the purpose for which the kite is to be employed, and they may be mounted in the frame, the one vertically above the other, as shown in the drawing, or in juxtaposition, or in alignment with one another, or in any other suitable manner.
  • a kite including a frame and a revolving motor mounted in the frame and embodying hollow semi-cylindrical bodies displaced radially with their axes at right angles to the line of flight.
