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; and by slidably adjusting the wing's position within the slit in the spine.

摘要： A model rotary wing aircraft is provided that includes a fuselage, a power plant, a main rotor, a tail rotor, and a drive apparatus. The power plant includes a passive cooling system to transfer heat produced by the power plant to the atmosphere. The passive cooling system consumes less than about five percent of the power produced by the power plant. The main rotor is driven by the power plant at a main rotor speed of rotation and the tail rotor is driven by the power plant at a tail rotor speed of rotation. The drive apparatus transfers power from the power plant to the main rotor and tail rotor to rotate the tail rotor at a tail rotor speed of rotation that is about three times greater than the main rotor speed of rotation to minimize the amount of power used by the tail rotor.

摘要： A rotary aircraft includes a cylindrically tubular hub mounting a plurality of outwardly extending, resiliently flexible blades. The blades are uniformly spaced around the hub and its central axis and fixed in pitch. Outer tips on each of the blades are downwardly turned and outwardly turned sufficiently to balance the lift generated by the blades from air striking the aircraft horizontally when the aircraft is in hover to provide passive stability to the aircraft. A pair of propellered electric motors are mounted on a diametrically opposing pair of the blades, pitched transversely to the central axis of the hub and to a plane perpendicular to the central axis, to simultaneously provide both lift and rotation. A battery supplies all power used by the aircraft while radio control circuitry in the hub permits variation of the power supplied to the motors for altitude control of the aircraft.

摘要： A toy helicopter is provided having a rotor that gradually accelerates to simulate the start-up of a full-scale helicopter, wherein the gradual acceleration is induced by frictional interaction between the surface of a drive shaft and the surface of a bore formed in the rotor hub. Actuation is accomplished by lifting an actuating shaft which extends from the rotor hub and drive shaft to activate a motor; returning the actuating shaft to its resting position deactivates the toy. The toy also provides a flashing light and audio mechanism to further simulate the operation of a full-scale helicopter.

摘要： A free flying aerodynamic toy that is manually launched and is composed of an elongate air foil having two identical surfaces that are joined to one another symmetrically of the longitudinal axis so that in response to rotation and translation through air, the surfaces sequentially cooperate with air flow thereover to produce lift. Circular stabilizer plates at opposite ends of the air foil produce vertical stability and have weighted peripheries to increase rotational inertia. Centrally of the air foil is a rib which divides the air foil into two symmetrical parts. The parts extend outward from the rib at a positive dihedral angle (an included angle less than 180.degree.) so as to enhance stability and reduce roll and yaw of the toy.BACKGROUND OF THE INVENTION1. Field of the InventionThis invention relates to an aerodynamic toy and more particularly to such toy that is capable of free flight so that it can perform maneuvers upon being thrown into the air by the user thereof.2. Description of the Prior ArtU.S. Pat. No. 2,501,442 (244-153) discloses an air foil kite which contains a rotating air foil that rotates with respect to a central shaft which is supported at the ends of threads or strings, the opposite ends of the strings being controlled from the ground by the user of the device. U.S. Pat. No. 3,262,656 (244-10) discloses a wing rotor which employs variable control surfaces and has an autorotating wing having a negative dihedral angle.U.S. Pat. No. 3,439,887 (244-10) discloses a rotary wing having moveable parts for effecting control of the same during flight.SUMMARY OF THE INVENTIONAccording to the invention there is an air foil capable of producing lift in response to rotation about the longitudinal axis thereof. At opposite longitudinal ends of the air foil are end plates which reinforce the air foil and act as vertical stabilizers. The end plates are of composite construction with concentrated weight at their outer peripheries to increase rotative inertia. The air foil, in a preferred form of the invention, is formed by two symmetrical portions which taper toward the longitudinal center to form a positive dihedral angle. Such preferred form has improved stability, particularly in turbulent air.An object of the present invention is to provide a rotary wing toy that is constructed so as to be self-stabilizing on the roll axis and the yaw axis. This object is achieved by the present invention by providing a wing having a centrally disposed rib with respect to which opposite surfaces form a positive dihedral angle so that when the wing varies from a horizontal attitude the air foil surface experience lift differential so as to restore the device to horizontal.Also contributing to the stability of the free flying rotary wing of the invention are vertically oriented flat end discs. The end discs are substantially flat or discontinuity free and have peripheries of relatively greater weight so as to interact with air currents to stabilize the device as well as possessing rotational inertia to promote smooth rotation of the wing.Another object of the invention is to provide substantial lift even in circumstances where the relative speed between the air foil surface and the air is slight. This object is achieved according to the present invention by providing a pair of air foils having a large camber behind which is a concave portion. The high camber region upon the wing enhances lift even at slow relative speeds and the concave portion contributes to this by reducing the stall speed of the air foil.By providing a wing capable of achieving the aforestated objects, the invention can be embodied in a light weight structure having a length of approximately 8 inches and a weight of approximately 9 grams. Such device can perform well indoors, where air turbulence is slight or outdoors where there are significant gusts or turbulence.The foregoing together with other objects, features and advantages will be more apparent after referring to the following specification and the accompanying drawings.

摘要： A toy helicopter rotor comprises a hub with rotor blades radiating therefrom. The hub comprises upper and lower hub parts having formations which releasably lock the parts together upon relative turning therebetween. Each blade has a root which is received in a complementary recess in the lower hub part and is trapped by the upper part, whereby the blades are secured to the hub. Projections on the blade roots retain the blades against radial, lateral and torsional movement and prevent them flying out of the hub in use.
