MODULAR AND ADJUSTABLE AUTOROTATIVE FLYER

摘要

An apparatus is disclosed for a modular and adjustable autorotative flying toy comprising: a planar, quasi tear-drop shaped wing having a substantially linear leading edge; an elongated cylindrical spine adapted to receive the wing; and a root constructed from elastomeric material, adapted to receive the spine. One end of the spine is inserted into an aperture in the root and fixed there by the root's elastomeric properties. The spine's cylindrical surface has a slit running parallel to its elongated axis from its distal end towards the root. The slit receives the linear leading edge of the wing, securing it relative to the spine and the root. The flight and rotational characteristics of the flyer may be adjusted by interchanging its components for alternative components that have different size, shape or weight. The flight and rotational characteristics of the flyer may also be adjusted by slidably adjusting the wing's position within the slit in the spine. When being used, the device is propelled upward or dropped from a height and autorotates about its center of mass during descent.
