ABSTRACT:
A rotary wing device has a circular stabilizer disc and, secured normally thereto, a bilaterally symmetrical wing member having a first symmetry axis intersecting the center of the stabilizer disc. The ends of the wing member at the first symmetry axis are connected through pin connections to a string harness whereby the device functions as a kite when the wing member rotates about the first symmetry axis. At least one guy wire connects the frame of the stabilizer disc to the frame of the wing member in each quadrant of the device. The same device may function in free flight without the string harness. The device preferably is fabricated from rod or tube frames covered with plastic films.
