Problems solved by technology

[0004] Regarding the rapidity of the boat performance, most domestic high-speed boats are single-body planing boats. When the Froude number is large enough, this boat type will appear "porpoising" phenomenon, which seriously affects the speed of the boat. Seakeeping and Stability

Abstract

The invention discloses a high-speed multi-body planing boat combined with hydro pneumatic dynamics for stabilization. A boat body is integrally of a three-piece-body structure, and comprises double boat bodies symmetrically arranged, a central small piece body is arranged on the symmetry axis of the bottoms of the double boat bodies, and front stabilization grid fins and rear stabilization grid fins are correspondingly and symmetrically arranged on the two sides of the double boat bodies; the front stabilization grid fins and the rear stabilization grid fins structures inclined upwards, and are correspondingly connected with the double boat bodies through bolts smoothly. According to the high-speed multi-body planing boat combined with hydro pneumatic dynamics for stabilization, the seakeeping performance is high, and the stability is high.

Description

technical field [0001] The invention relates to the technical field of planing boats, in particular to a high-speed multi-body planing boat combined with hydrodynamic anti-rolling. Background technique [0002] High-speed boats have become an inevitable trend in the development of boats at home and abroad. At present, the maximum speed of high-speed boats in my country is about 60 knots to 70 knots, which is still far behind the related technologies of European and American countries. In the development of high-speed boats, how to make the design of the boat take into account good technical performance, that is, "rapidity", "seakeeping" and "stability" is an urgent problem to be solved. [0003] In the technical performance of a boat, seakeeping is a crucial performance. The movement and acceleration of the boat in waves will cause hull slamming, deck waves, increased resistance, and propeller speeding, which will cause damage to the hull structure, damage to equipment and ...
