Definitions

  • the present invention relates to a flying toy.
  • the present invention relates to a motorless model aeroplane toy in which the aeroplane is able to fly in a substantially circular path under the control of a user manipulating a plurality of control lines to the aeroplane, the user being able to affect the interaction of the yaw/pitch/roll coupling and centrifugal and gravitational forces on the aeroplane to cause the aeroplane to execute various flying manoeuvres.
  • Flying model aeroplane toys may be classified as being either radio controlled or line controlled. Although radio controlled model aeroplane toys are the most popular, they are also the most expensive and technically problematic. Line controlled model aeroplane toys have maintained some popularity mainly due to their simplicity of operation. There are two main kinds of line controlled model aeroplanes, these being either motor driven or motorless model aeroplanes. While the motor provides the necessary thrust in motor driven model aeroplanes, motorless model aeroplanes rely upon the user to manually swing the line in a circular motion so as to generate the necessary centrifugal force on the aeroplane to elevate it an appropriate altitude for flying in a substantially circular path around the user.
  • a line controlled, motorless model aeroplane toy is known that is controlled by whip action as exerted through a flexible "fishing rod" type handle.
  • the whip action is necessary to provide the thrust for the aeroplane's flight.
  • the whip action will not in itself ensure that such thrust is controllable unless the aeroplane has a tail or similar vertical aerodynamic surfaces. It is therefore an object of the present invention to provide a motorless model aeroplane toy that does not require a vertical tail or similar vertical aerodynamic surface to control the flight characteristics of the aeroplane.
  • a flying toy comprising:- a body having a fore-and-aft centre line and an aerodynamic surface on each side of the centre line but not having an aerodynamically functional surface adapted to control or counter yawing, first and second control lines connected at respective first ends thereof to the body, the first control line being connected forward of the centre of gravity of the body, and the second control line being connected rearward of the centre of gravity of the body, and a handle to which the respective second ends of the first and second control lines are connected at space apart locations on the handle, the said handle adapted to be gripped by a user, the arrangement being such that the body may be flown in a substantially circular path by a user swinging the control lines in a circular motion so as to generate sufficient force to keep the body airborn, whereby manipulation by the user of the control lines will affect the interaction of the yaw/pitch/roll coupling and centrifugal and gravitational forces on the body to cause the body to execute desired flying manoeuvres.
  • the arrangement being such that the body may be

  • Fig. 2 is a plan view of the flying toy of Fig. 1 in which the position of the handle relative to the aeroplane causes the aeroplane to bank toward the user and ascend

  • Fig. 6 is a front view of an operator flying the toy of Fig. 4
  • Fig. 7 is a plan view of an operator using the toy of Fig. 1 .
  • BEST MODE FOR CARRYING OUT THE INVENTION The flying toy 10 shown in Figs. 1 , 2 and 3 consists of a motorless model aeroplane 1 2, a first control line 14, a second control line 1 6, and a handle 1 8 for a user.
  • the model aeroplane 1 2 has a body 1 5, aerodynamic surfaces in the form of aerofoils or wings 24 and 26 and a substantially transverse aerodynamic tail 22 but no aerodynamically functional rudder or tail plane.
  • the control lines 1 4, 1 6 are connected to opposite ends of the handle 1 8 and are connected to the aeroplane 1 2 across the centre of gravity 20 of the aeroplane 1 2.
  • the control line 14 is connected to the aeroplane body 1 5 forward of the centre of gravity 20 and the control line 16 is connected to the near wing 26 rearward of the centre of gravity 20.
  • the model aeroplane 1 2 may be flown in a substantially circular path by the user swinging the control lines 14, 1 6 in a circular motion (see Figs. 6 and 7).
  • the aeroplane 1 2 will be maintained in an elevated position when a sufficient centrifugal force is generated from the swinging action.
  • the user is able to manipulate the control lines 14, 1 6 to affect the interaction of the yaw/pitch/roll coupling and centrifugal and gravitational forces on the aeroplane 1 2 to cause the aeroplane 1 2 to execute desired flying manoeuvres.
  • the swinging action of the control lines 14, 16 is achieved by the user using both hands at separate times to carry out a smooth, rhythmical movement of the handle 18 similar to the movement practiced in the art of tai chi.
  • This action can involve a co-operation of the body and mind in the form of mental concentration and physical co- ordination, which will provide a benefit to the health and fitness of the user and allow the user to fly the model aeroplane 1 2 for protracted periods while maintaining his or her balance as they do not necessarily have to spin around.
  • the aeroplane 1 2 may be caused to execute desired flying or aerobatic manoeuvres by the user manipulating the control lines 14, 1 6 in combination with the user's swinging action which imparts centrifugal force on the aeroplane and with the wind conditions.
  • the manipulation of the control lines is achieved by subtle movement of the handle 1 8.
  • the handle 1 8 can be held in a horizontal plane, vertically or at any desired angle.
  • the elevation of the aeroplane 1 2 is kept constant by gripping the handle 1 8 in the position shown in Fig. 1 relative to the aeroplane, whereby the axis of the handle 1 8 is more or less parallel to the fore-and-aft axis of the aeroplane 1 2.
  • the tension on both the first control line 1 4 and second control line 1 6 is substantially equal so that the wings 24, 26 of the aeroplane 1 2 are square to the airflow and the lift generated across each wing 24, 26 is substantially equal.
  • the effect of the centrifugal and gravitational forces is defined as being neutral.
  • the axis of the handle 1 8 need not be parallel to the fore- and-aft axis of the aeroplane 1 2 so long as the fore-and-aft axis of the aeroplane 1 2 approximately marks out the tangent of the arc followed by the aeroplane 1 2.
  • the aeroplane 1 2 will yaw or sideslip at the rear control line 1 6.
  • the direction of airflow over the wings 24, 26 will change, increasing lift on the far wing 24 and decreasing lift on the near wing 26, so as to cause the aeroplane 1 2 to roll and bank towards the user.
  • the embodiments of Figs. 4 and 5 merely indicate variations in body configuration with the same numerals being used as used with the embodiment of Fig. 1 .
  • the tail plane 22 of each of these embodiments has a vertical portion 22a and a substantially horizontal portion 22b but no aerodynamically functional tail plane or rudder.
  • the yaw/pitch/roll coupling referred to above is the conventional operational parameters of flying.
  • yaw is introduced into the movement of the body by the action of the operator pulling on the control lines as described above. Pitch then comes into play as the tail drops under the force of gravity and roll is the consequence of yaw and pitch.
  • the aerodynamic surface on each side of the centre line may be continuous as shown in Fig. 5 or may be a rotor in the case of a helicopter or an autogyro.
  • the centre of gravity may be on or off the centre line of the body and the body may or may not be symmetrical about the centre line.
  • the attachment point of each control line to the body may be selected as desired as long as one control line is forward of the centre of gravity and one is aft of the centre of gravity.
  • the control lines may be of different lengths.
  • the aerodynamic manoeuvrability of the aerodynamic body will depend on variables such as its size, mass, the position of its centre of gravity, its aerofoil shape and the like, in combination with the particular location of the control lines.
  • the body may also take the form of a bird or other animal, helicopters, autogyros, canard-type craft, space craft or any other object having a body that is able to be flown in the manner of the present invention.
