FIELD: transportation. ^ SUBSTANCE: retractable hydroski (1) is coupled to a float by means of hinge (7) in the airplane nose part, and, at the plane rear, by means of telescopic hydraulic rack (4). The length of hydroski (1) is equal to that of seaplane float. Note that hydroski (1) has a saber-like shape with a keel angular component (3) and a horizontal component (2). The bottom surface of horizontal component (2) is flat, without planning steps. The hydroski inside is hollow. ^ EFFECT: decrease in resistance of water and shock loads at landing and an opportunity of sliding on over ice or snow covered surfaces. ^ 6 dwg |
