Stern ends are arranged of streamlined shape: in plan - parabolic shape, at side view they have streamlined shape of truncated cones with cone tops shifted down to level of superposition of cone generatrix with lower part of balloons. Streamlined shape of ends is formed by means of balloon crossing at sharp angle with part of balloon cylindrical surface of the same radius and part of elliptical surface. Outboard motorboat has elastic gussets, every of which is connected to transom and balloon and antispray elastic cloth fixed to boat fore part and to pneumatic beam. Under elastic cloth detachable rigid element is installed, one end of which is installed in fore part of boat, and the other one - in pneumatic beam.EFFECT: improved operational properties of device.3 cl, 2 dwg |
