PCT No. PCT/FI95/00261 Sec. 371 Date Nov. 13, 1996 Sec. 102(e) Date Nov. 13, 1996 PCT Filed May 17, 1995 PCT Pub. No. WO95/31347 PCT Pub. Date Nov. 23, 1995The present invention relates to a hydrocopter. A hydrocopter is a vehicle by which it is possible to move over water, particularly in an archipelago, under difficult conditions, e.g., during the thaw. The waterproof hull of the hydrocopter bears against the underlying surface, such as snow, ice, slush or water, and is driven forward by an air propulsion unit mounted on top of the hull. The problem with the current hydrocopters is that they are very difficult to steer and uncomfortable to ride in. Division of the hydrocopter hull into two portions connected to each other by a hinge joint, in accordance with the invention, makes it possible to use frame steering. This new structure makes the hydrocopter easier to handle. The invention provides a vehicle which has a small turning radius and which is steerable even at very slow speeds. |
