Abstract

An object such as a ski 1 is adapted to move in a fluid such as air. Ski 1 has a face 2 normally exposed to resistance of the air in which it is travelling. An aperture 3 is provided in the face 2. A blade 12 is supported to rotate in the aperture about an axis 11. Blade 12 has cross section shape normal to the axis with opposing tips 12A, 12B of the blade bent in opposing directions whereby air flowing across the blade causes the blade to rotate about the axis 11. In use movement of the ski causes fluid to flow across the blade so it rotates, and the rotating blade is stated to contribute to an increase in the propulsion and/or speed of the ski. The object may be a vehicle rather than a ski.

Description

<p>Title: Object with rotating blade to improve propulsion and/or speed
The present invention relates to an object with rotating blade to improve propulsion and/or speed. This includes objects, which are self-propelled, e.g. skis using gravity, and objects, which have motors or other devices to propel themselves.</p>
<p>According to the present invention there is provided an object adapted to move in a fluid, said object comprising: a) an object face normally exposed to resistance of the fluid in which it is travelling, b) an aperture in the object face, c) a blade supported to rotate in the aperture about an axis, said blade having a cross section shape normal to the axis with opposing tips of the blade bent in opposing directions whereby fluid flowing across the blade causes the blade to rotate about said axis, in use movement of said object causing fluid to flow across the blade so it rotates, and said rotating blade contributing to an increase in the propulsion and/or speed of the object.</p>
<p>Preferably a frame is provided in the aperture to support the blade for rotation.</p>
<p>Preferably said axis is substantially horizontal.</p>
<p>Preferably the aperture is circular and the blade is circular.</p>
<p>Preferably a nozzle is provided on the downstream side of the aperture. The nozzle may enhance thrust generated by said blade.</p>
<p>Preferably a one-way device is provided to ensure rotation of the blade in one direction only one way. The one-way device may be a ratchet.</p>
<p>The object may be propelled by gravity. The object may be a ski, e.g. an alpine ski.</p>
<p>Alternatively the object may be propelled by a motor or other device, the object may be a vehicle, such as a road vehicle, boat, submarine or aircraft.</p>
<p>Preferably the aperture is located at the front of an object.</p>
<p>An embodiment of the invention will now be described with reference to the accompanying drawings in which: Figure 1 shows a perspective view of an object in the form of the front section of a ski, and Figure 2 shows a cross view of a frame supporting a blade.</p>
<p>Referring to Figure 1 there is shown the tip of a ski 1. Ski 1 may be of a type well known in the art and will include boot bindings (not shown). Ski 1 is adapted to slide generally on the surface of snow under the influence of gravity. In doing so, the ski has a front face 2 exposed to resistance of the air in which it is travelling. Ski front face 2 has an aperture 3 therein.</p>
<p>Mounted in aperture 3 is a circular frame 10 supporting, for rotation about a horizontal axis Ii, a circular blade 12. Blade 12 has cross section shape normal to the axis with opposing tips 1 2A, 12B of the blade bent in opposing directions whereby fluid flowing across the blade causes the blade to rotate about axis I I in the direction shown by the arrows. Blade 12 and frame 11 may be made of any suitable material, such as metal or plastics, or combinations thereof.</p>
<p>An optional tapering nozzle 13 is provided on the downstream side of the aperture.</p>
<p>A one-way device, in the form of a ratchet 14, is provided to ensure rotation of the blade in one direction only, as shown by the arrows.</p>
<p>In use, as the ski moves in a forward direction, airflow across the blade and the tips I 2A, I 2B cause the blade to rotate. Air, as driven by the blade 12, passing through the frame contributes to an increase in the propulsion and/or speed of the object. The nozzle 13 enhances thrust generated by blade 13 and makes the airflow more streamlined. Tips 21A, l2B are shown bent a small amount around 100 but could be a different angle, such as 350 Blade 13 is powered by air acting upon it. The faster the ski moves, the faster the blade will rotate and improve the speed of the ski (although there is obviously a limit to the ski speed).</p>
<p>Obviously a pair of skis as described above would be used by a skier. It is envisaged that skis used for racing would most benefit from the invention. Such skis could also improve turns and jumps.</p>
<p>The object of the invention may be other than a ski. For example it could be a vehicle such as a road vehicle, boat, submarine or aircraft. The aperture housing the blade would ideally be located at the front of the vehicle.</p>
<p>The rotation of the blade would provide increased propulsion and/or speed for the vehicle, so reducing the power required to pmpel it from its own motor. This would lead to fuel economies.</p>
<p>It may be desirable to increase the mass of the blade. This could be achieved in various ways, such as providing a sphere of material around the centre of the blade or by increasing the mass of the blade or parts thereof using heavier materials.</p>
<p>It is also envisaged that an object could support two or more blades for rotation in respective apertures.</p>
<p>The blade provides increased propulsion and/or speed for an object for one or more of the following reasons: a) the blade generates a propulsive force also known as thrust, b) the rotation of the blade generates a centripetal force, c) the blade produces a moment, d) rotation of the blade "digests or scoops" fluid matter by virtue of the direction of rotation and therefore decreases the fluid frictional force of an object, e) the rotation of the blade is proportional to the linear motion of the object, and f) the rotating blade makes use of the kinetic energy of an object to maximise the amount of fluid matter acting upon it.</p>
<p>Although the speed of rotation of the blade is proportional to the speed of the object, it is not considered that the blade would provide infinite speed to the object. The object will have a terminal velocity in the medium in which it is travelling, and this terminal velocity may be increased by the blade.</p>
<p>It is considered that the size of the blade would be optimised to suit the volume of the object and the size of the face of the object. The invention may take a form different to that specifically described above.</p>
<p>Further modifications will be apparent to those skilled in the art without departing from the scope of the present invention.</p>
