Two part flying kite - consists of rigid rotary part on horizontal axis

摘要

The kite attached to a string consists of two rigid sections, one of which gives the kite lift and is in the form of a part rotating on a horizontal axis and set rotating by the wind. The side opposite the wind lifts up as a result of Magnus effect. At right angles to the. first part is a disc the centre of which is in the middle of the pivot axle of the lift-part. The rotary disc imparts lateral stability. The string is attached by means of a fork on the axle ends. ADVANTAGE - The kite is not flat as is usual and has connections for the string so that the string does not wind onto them.
