Abstract
The invention discloses a rear-hydrofoil combined double-body planing boat which comprises a boat body, a propelling device and a striking hydrofoil arranged at the rear portion of the boat body. An improved double-body planing boat line type is adopted for the boat body from a boat bow to a position of a midship close to the rear portion. The bottom of the rear boat body is integrally lifted in step mode at the position of the midship close to the rear portion. A line type of the bottom of the boat body is that a deep V shape is transited to a shallow V shape gradually from the boat bow to the position of the midship close to the rear portion, or the shallow V shape is transited to a middle arc to connect double shallow V shapes gradually, or a middle horizontal line is connected with the double shallow V shapes. A gap between the double bodies is that a similar isosceles trapezoid with a chamfer is gradually transited to an arc and to a shallow V shape or the horizontal line to be connected with the position of the midship close to the rear portion smoothly. The rear-hydrofoil combined double-body planing boat combines advantages of a planing boat and a foilcraft and overcomes intrinsic shortcomings of a single boat type, and the comprehensive performance of the rear-hydrofoil combined double-body planing boat is better than that of the planing boat and the foilcraft. Simultaneously, transverse stability and shipping direction stability are greatly improved compared with the planing boat, and an excellent characteristic of the planing boat of being capable of surfing on a beach is reserved.

The specific embodiment
The invention will be further described below in conjunction with drawings and Examples.
Such as Fig. 1～shown in Figure 11, the present invention includes hull 1, propelling unit 2 and be arranged on cutting of the hull front portion wing 3 of striking,
Cut the wing 3 of striking and comprise horizontal hydrofoil body 31 and several symmetrically arranged pillar 32, hydrofoil body 31 is captiveed joint with hull 1 both sides by several pillars 32, and the stern bottom surface of hull 1 consists of planing surface.The ship bow adopts the catamaran planing craft line style of improvement to the partially rear hull of midship, rear hull bottom is located partially afterwards whole step at midship and is promoted, partially rear hull adopts the dark V-type by Fig. 2 to be transitioned into gradually shallow V-type to hull bottom line style from the ship bow to midship, or connect two shallow V-types by the middle circular arc that shallow V-type is transitioned into Fig. 3 gradually, or the by-level line connects two shallow V-types; The binary gap is transitioned into gradually shallow V-arrangement or the horizontal shape that circular arc is transitioned into Figure 10 again by the approximate isosceles trapezoid with rounding and locates partially afterwards suitable connecing with midship.
As shown in Figure 1, the waterline length that vertically immerses the water surface take glider is L, position at the L1=1/5-1/4L of glider midship after partially, rear hull bottom integrated step upwards promotes, the height T1 that promotes is the 1/3-1/2 of captain boat body static draft degree of depth T, be T1=1/3-1/2T, the hull bottom is extremely shallow V-type or horizontal type after this part.
The structure of cutting the wing 3 of striking adopts one of following shape: the interference that single T shape is as shown in Figure 5 cut the 301 pairs of waves of the wing of striking is not too responsive, and glider has good navigability, and realizes more easily that T shape is cut on the wing 301 of striking and turn over.Because wing plate all is immersed in the water, only has pillar 32 to cut the face of striking, running resistance is little.When T shape is cut the wing 301 of striking and is installed, two pillars 32 cutting the face of striking are kept one 2 °-4 ° outer subtended angle degree along the plane of symmetry of cox's direction with the vertical midship section of ship, be conducive to promote and navigate by water dynamic stability.
Single V-arrangement shown in Figure 6 cuts the wing 302 of striking, and single inverted V-shaped shown in Figure 7 cuts the wing 303 of striking, and the inverted V-shaped of single band edge shown in Figure 8 cuts the wing 304 of striking.The single trapezoidal wing 305 of striking that cuts shown in Figure 9 generally provides lift by the flat wing, and flank guarantees stability, and its 1ift-drag ratio is higher than general V-wing.The shallow V-arrangement of single ladder shown in Figure 10 cuts the wing 306 of striking and is particularly conducive to and improves navigability and course stability, and its 1ift-drag ratio also general T shape wing is high; Owing to cutting the face of striking, have preferably self-stability, better than the comprehensive navigation performance of general V-wing.
Figure 11 shows that the bench section of three kinds of hydrofoil bodies 31, be followed successively by from top to bottom improvement airfoil type, approximate arc, crescent, Figure 12 is symmetrical wing pillar 32 bench section.Symmetrical wing pillar 32 has reduced the resistance of current greatly, and the hydrofoil lift of three kinds of fleetline sections is greatly enhanced.
Because the existence of hydrofoil lift, hull front portion and hot separation mainly support ship weight by the hydrodynamic force that hydrofoil and planing surface provide to glider of the present invention when navigating by water at a high speed.Conventional gliding-hydrofoil craft and glider are owing to high speed slide, and hull splashes generation.Glider of the present invention has overcome the shortcoming that the intrinsic side direction of monomer sailing yacht type is splashed and caused rapidity, swaying property and economy to descend, the Combination properties such as its ship type, drag characteristic, stability and road-holding property are better than glider, and its rapidity has improved more than 10% than glider.
In addition to the implementation, the present invention can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
