The present invention is described in further detail below in conjunction with accompanying drawing.
Shown in Fig. 1, Figure 1A, Figure 1B, a kind of glider of the present invention with catamaran three-channel hull, the top of this hull 1 is deck 1a;
The left side of hull 1 is left leg 13;
The right side of hull 1 is right leg 14;
The front end of hull 1 is a stem 11;
The rear end of hull 1 is a ship stern 12;
The bottom 1b of hull 1 is provided with A leg end face 7, B leg end face 8, A slideway 2, B slideway 3, C slideway 4, A planing surface 5 and B planing surface 6; B slideway 3 is along the line of centers setting, and is sector structure; The both sides of B slideway 3 are A planing surface 5 and B planing surface 6; Be A slideway 2 between A planing surface 5 and the right leg 14, and right leg 14 have A leg end face 7 at ship stern 12 places; Be C slideway 4 between B planing surface 6 and the left leg 13, and left leg 13 have B leg end face 8 at ship stern 12 places.
The line of the end point H of the end point G of A leg end face 7 and B leg end face 8 is called leg cut-off rule GH, and this leg cut-off rule GH is divided into former and later two parts with hull 1, i.e. back hull 1c and preceding hull 1d.In the present invention, upward A leg end face 7, the B leg end face 8 of symmetric design place static waterline below to back hull 1c.
Design-calculated of the present invention has the glider of catamaran three-channel hull, in the process of low speed (the Fu Rude number is less than 1.0) navigation, because the length of back hull 1c is smaller or equal to glider captain's 1/4th, then the area of contact of A leg end face 7, B leg end face 8 and water is little, helps reducing friction drag.
Shown in Fig. 1 C, the cross section (the A-A view of Fig. 1) of design-calculated glider of the present invention on preceding hull 1d is binary list conduit form, and this section is the typical bench section of preceding hull 1d.Static waterline and B chute 3 have been formed an osed top air by-pass passage, and this passage is made up of the ellipse conduit section and the water surface.Static waterline and A chute 2 (or C chute 4) have been formed the air by-pass passage of an opening, and outer side enclosure wall (left leg 13 and right leg 14) is positioned at static waterline top, because outer side enclosure wall is not extended entry, has alleviated hull structural weight herein.
Shown in Fig. 1 D, the cross section (the B-B view of Fig. 1) of design-calculated glider of the present invention on the hull 1c of back is the catamaran three-channel form, and this section is the typical bench section of back hull 1c.When glider was static, B chute 3, A chute 2 and C chute 4 all were positioned at static underwater.When glider slides at a high speed (the Fu Rude number is more than or equal to 1.0), stem lifts, and the drinking water of ship stern also reduces, and the top of B chute 3, A chute 2 and C chute 4 is positioned on the water surface, has formed three osed top air by-pass passages; In the inside of B chute 3, here be compressed from stem 11 below inlet airs, and mix with the water of bottom 1b; The wave that A planing surface 5 and B planing surface 6 form in the navigation process is limited in the inside of A chute 2 and C chute 4.
Double water column structure has been adopted in hull 1 bottom of this glider, is intermediate channel (B slideway 3) between two displacement hulls (A planing surface 5, B planing surface 6), and two displacement hulls are with the vertical bottom 1b that connects whole hull 1 of line of centers symmetry.
Because the stem 11 of design-calculated hull 1 of the present invention is above static waterline, therefore, the lifting point is located on the knuckle line, the knuckle line 5a that is A planing surface 5 is provided with lifting point A, the B knuckle line 6a of B planing surface 6 is provided with lifting point B, and the line of lifting point A and lifting point B is called slideway cut-off rule AB, and this slideway cut-off rule AB is divided into straight shape slideway 3a and fan-shaped slideway 3b with B slideway 3, B slideway 3 structure designs of two sectional type help glider the entering and compress of air in motion process.
In the present invention, the Front-end Design of B slideway 3 is become fan-shaped slideway 3b, increased the width of stem 11, make the utilized area on deck increase.
Design-calculated of the present invention has the glider of catamaran three-channel hull, and deck 1a is trapezoidal, aspect ratio between 1.5 to 2.5, wherein, d 1The width of expression ship stern, d 2The captain of expression glider, aspect ratio is meant the captain of glider and the ratio of the width of ship stern, i.e. d 2: d 1=1.5~2.5 (referring to shown in Figure 1).
Referring to shown in Figure 2, design-calculated two-stage structure B slideway 3 of the present invention plays and forms the air-sprung effect.When navigating by water at a high speed (the Fu Rude number is more than or equal to 1.0), A planing surface 5, B planing surface 6 are subjected to the effect of hydrodynamic lift, stem 11 liftings of hull 1, and ship stern 12 drinking water of hull 1 reduce, and form sliding state, have reduced running resistance.Because the loudspeaker entrance height of the fan-shaped slideway 3b of B slideway 3 constantly descends, after arrival slideway cut-off rule AB is cut apart the cross section at place, transfer straight shape slideway 3a to, here be compressed from loudspeaker inlet inlet air, form higher air pressure, further raise hull, reduce draft, thereby reduce wetted surface area.The air of compression moves in B slideway 3, mixes with current, forms air-water mixture, because the density of air or air-water mixture is all much smaller than water, therefore plays the lubricated resistance effect of falling at the straight shape slideway 3a place of B slideway 3.
Design-calculated of the present invention has the glider of catamaran three-channel hull, reduces because positice ground effect causes absorbing water in the conduit, and the gas-bearing formation drag reduction effect in the conduit, facilitated the decline of hull bottom friction drag jointly, help improving ship's speed.Simultaneously, diffusion that the A slideway 2 of ship stern 12 both sides, C slideway 4 have suppressed to slide part ship wave in the process, reduced the navigation wave to bunding wash away and near the motion effects of ship.
Hull 1 bottom design becomes the catamaran three-channel structure, when glider produces heel, because hull transverse width broad can produce bigger restoring moment, has guaranteed the lateral stability of glider.Simultaneously, under the displacement unmodified situation, increase, can reduce draft, help the navigation in the shallow water at the hull transverse width.
Design-calculated of the present invention has the glider of catamaran three-channel hull, adopted ellipse conduit profile configuration, in high speed navigation process (the Fu Rude number is more than or equal to 1.0), made full use of planing surface (A planing surface 5, B planing surface 6) hydrodynamic lift, the air cushion lifting of B slideway 3 and the effect of gas-bearing formation drag reduction, the leg end face of ship stern 12 both sides (A leg end face 7, B leg end face 8) and the wave inhibit function of contiguous outer side enclosure wall (left leg 13 and right leg 14), has shallow draft, speed of a ship or plane height, river channel erosion is influenced advantages such as little, be adapted at the navigation of shallow water territory and offshore zone, can be used as quick marine communication means.
