Abstract: A new saucer-shaped aerodynamic throwing toy is disclosed. The flight body is provided with a shaft on which a propeller is mounted, resulting in an unusual "hopping" effect during use without decreasing the overall flight time. The shaft is removable, thereby allowing the toy to be converted into an implement with more conventional characteristics. The pitch of the propeller blades is adjustable, and the body may be provided with small battery powered lights to enable the toy to be used at night.

Abstract: A remote-controlled autogyro visually and functionally simulates a helicopter with stub wings (e.g. the Hind D), so that an expendable helicopter-simulating target is produced. The target has a fixed angle rotor shaft, the rotor being solely aerodynamically controlled. The rotor blades have a negative pitch angle, and a positive conning angle. The engine is mounted at the front of the fuselage and has a downthrust angle, and the horizontal stabilizer also slopes downwardly aft. The rotor is at about the center of lift (horizontally) of the wings, and the wing span is about 50-60 percent the length of the fuselage. The ailerons and tail rudder are electrically interconnected. Remote control is provided for the elevators ailerons, and engine speed.

Abstract: A hand-launched rotary flight device comprising a central hub from which a plurality of preferably equiangularly spaced-apart blades extends. The central hub has a finger grip portion with which the hub is rotatable, which finger grip portion extends radially from a blade-mounting portion of the hub in a direction away from the blades. The finger grip portion is dimensioned and configured to enable manual gripping thereof, ideally between the thumb and forefinger of the operator, to permit launching the device by hand into a rotary motion flight path without necessity of a mechanical launching device.

Abstract: A helicopter toy including a hollow body which forms an elongated conduit. A generally elongated planar tail member is secured to the body at one end of the body and is axially aligned with the body. The tail member also includes a generally planar flap secured thereto. The flap is generally horizontal and is arranged at any angle to the plane of the tail. A multi-bladed, boomerang-shaped propeller is rotatably secured to the body so that the body is suspended from the propeller. The toy may be thrown to describe a curved flight path, whereby the toy will return to the operator, or different flight patterns depending on the selected propeller. Air passes through the hollow body to continually keep the hollow body aligned with the path of flight of the toy.

Abstract: An aerial toy to be projected into the air, the toy having a rotor to slow the descent. The rotor is locked to be coplanar with the body while the toy is projected and during the ascent of the toy. At the apex of flight, the toy changes its attitude, the front pointing down, and a gravity operated driver releases the lock for the rotor. The rotor then rotates, providing enough aerodynamic drag to cause the toy to have a slow descent, and a soft landing.

Abstract: A rotary fluid propelled device employing a natural theory of constriction and controlled redistribution to convert fluid flow to rotary mechanical energy. Two conical shell-shaped compartments opposite each other are connected by a midaxis transfer band forming the device. Rotary mechanical energy, mechanical lift force and high visual interest result from the operation of the device.
