Problems solved by technology

This makes shipbuilding companies face a difficult problem: if they want to meet the needs of users, they must invest in a new mold for each improvement of the needs of the existing production process.
The above problems cause the existing technology to be unable to manufacture CM high-speed boats that meet the demand

preparation example Construction

[0041] A kind of preparation method of CM high-speed boat is briefly described as the following steps:

[0042] Step 1. Confirm the technical parameters of the target boat and prepare raw materials and equipment.

[0043] Step 2, according to the length L of the ship and the type of propulsion system, install the stern seal template 2 and the power output module 3 at the specified positions of the hull forming mold 1; prepare the molding molds for fenders, decks, cabins and auxiliary components; Coat the mold with release agent.

[0044] Step 3, molding the CM hull 19 in the following order.

[0045] 1) The outer panel of the hull is formed by the general vacuum introduction process A1), spraying gel coat resin on the surface of the mold; paving fiber reinforcement materials; laying auxiliary materials for diversion resin, covering and sealing the vacuum film; vacuum introducing resin glue. Cured at room temperature for 6 hours, raised to 65°C, and cured for 6 hours.

Embodiment 1

[0055] Depend on Figure 1-8 As shown, the present embodiment is a series of CM high-speed boats, the main purpose of which is official law enforcement and personnel transportation. The main dimension is: maximum boat length L=L AB4 =15m, molded width B=2.8m, molded depth D=1.5m, full load draft d=0.45m, displacement△=7.2t; other lengths of this series of high-speed boats are: L AB3 =13.5m, L AB2 = 12m and L AB1 = 10.5m. Boat length L=15m. Main technical performance: speed ≥ 87km / h (47 knots), power 2*257kW diesel engine, water jet propulsion, crew 16 (including crew 2), load capacity 2.5t (including crew weight), seaworthiness : Guaranteed survival under level 5 sea conditions (keep upright and low-speed navigation), low-speed cruising under level 4 sea conditions (37km / h, about 20 knots), and an endurance of 300km. It has the property of not sinking when the tank is damaged.

[0056] The CM hull of this embodiment adopts vinyl ester resin as the matrix material, and u...

Embodiment 2

[0083] Depend on Figure 12 Shown in 16, 17 and 18 among middle, present embodiment is a kind of open boat type in CM high-speed boat series, and purpose is official law enforcement and water area patrol. RHIB hull structure is adopted, and the ship's side is equipped with high-elasticity fenders filled with polyurethane outer armor and foam inside; the main dimension is: captain L AB2 =12m, molded width B=2.8m, molded depth D=1.5m, full load draft d=0.45m, displacement △=4.5t; main technical performance: speed ≥ 87km / h (47 knots), equipped with power 2*257kW Diesel engine, water jet propulsion, 12 crew members (including 2 crew members), load capacity 2.0t (including crew weight), seaworthiness: guaranteed survival in class 5 sea conditions (keep upright, can sail at low speed), class 4 sea conditions Cruise at low speed (37km / h, about 20 knots), with a cruising range of 250km. It has the property of not sinking when the tank is damaged.

Abstract

The invention belongs to high-speed boats, and particularly relates to a CM high-speed boat. The CM high-speed boat is a semi-planing boat which is characterized in that a bow is in a high-speed surface naval boat shape, a V-shaped planing boat shape is formed from a midship to a stern, and the bow and the stern are connected through a smooth transition molded line. The CM boat body of the high-speed boat is molded by a mold; a stern transom template is arranged within a certain length range in the boat body forming mold to separate a mold cavity, so that various boat bodies with different lengths and similar hydrodynamic characteristics can be manufactured. The CM high-speed boat has the advantages that the boat bodies with different lengths are guaranteed, the boat bodies have similar sailing resistance characteristics, and the requirement that one boat type series comprises a plurality of long boat types is met.

Description

technical field [0001] The invention belongs to high-speed boats, in particular to a CM high-speed boat. Background technique [0002] The CM high-speed boat is a boat that uses CM (Composite Materials, composite materials) as the hull construction material and has a speed higher than 56km / h (30 knots). The CM mentioned herein refers to fiber-reinforced composite materials (Fiber CompositeMaterials). Thanks to CM's light weight, high strength, corrosion resistance, long life, good designability, and convenient molding, the application fields of CM high-speed boats are very wide. In the military field, patrol boats, assault boats, law enforcement boats, and unmanned boats; in the civil field, small and medium-sized high-speed boats such as sports boats, yachts, official boats, work boats, and traffic boats belong to the category of CM high-speed boats. [0003] A typical example is the common assault boat. This kind of high-speed small boat often appears in the performance ...
