The specific embodiment
For example the present invention is described in more detail below in conjunction with accompanying drawing:
As shown in Figure 1, the deck 1 of hydrofoil catamaran, two lamellar bodies 2 of hydrofoil catamaran and 3, the pillar of front and back hydrofoil is respectively 4 and 5,10 and 11, all is installed in the below, deck, links to each other with the bottom of lamellar body.Front hydrofoil 6 links to each other with pillar 4,5, and rear hydrofoil 9 links to each other with pillar 10,11.Two wing flaps 7 in front side, 8 are connected on the hydrofoil 6 by transmission shaft 16, and axle 16 links to each other with inner Fu.The post wing 12,13 links to each other with pillar 10,11 by axle 17,18 respectively. Wing flap 14,15 links to each other with hydrofoil 9 by axle 19.Pillar 4,5,10 in above-mentioned, 11 length need to be chosen according to the length of the post wing, and the area ratio of the post wing and pillar is between 0.3～0.4.The setting angle of pillar and hydrofoil is chosen as 0～2 °.
Shown in Figure 2, be front side hydrofoil constructional drawing, this structure is the symmetrical structure take the hydrofoil center line as axis of symmetry, about two wing flaps have identical function, adopt the twin props structure can make the hydrofoil system firmer, durable.Two wing flaps have respectively Fu separately to drive, because the existence of synchronous compensator being arranged, can also realize synchro control.The hydrofoil here and wing flap all are to adopt thin wing, wing section Thickness Ratio t=2y/C (2y is the wing section maximum ga(u)ge, and C is wing chord length), usually t=0.09～0.2.The resistance meeting less that such aerofoil profile is subject to is little to rate during high speed.
Shown in Figure 3, be rear side hydrofoil constructional drawing, about the post wing of a controllable type of two last installations of pillar, two post wings can be realized asynchronous control and synchro control equally, are determined by actual steering and corner.The rear side hydrofoil also has two wing flaps, can realize the function identical with front flap.Size for wing flap does not have strict regulations, but usually chooses 20% of hydrofoil area of conter.Hydrofoil needs to consider the impact of the angle of attack when mounted, and the angle of attack generally can not be too large, and is best between 0 ° to 2 °.
Shown in Figure 4, be front and back wing flap drawing in side sectional elevation, the shape of hydrofoil and wing flap, designed according to hydromechanical knowledge a variety of, need to be according to ship type and practical application, select the shape that is fit to.For the wing flap of design, because the restriction of Fu and actual machine device, the corner of wing flap can not be very large, and rotating speed should be very not large yet.For the designed wing flap of this patent, its corner generally is no more than ± and 10 °, rotating speed is generally 3 °/s, and maximum is no more than 4 °/s.Aspect ratio is an important technical index concerning wing flap, and here we adopt the NACA aerofoil profile, and design aspect ratio λ=b/C(b is span length) between 1～6, select.
Shown in Figure 5, be post wing structure birds-eye view, the post wing here is mainly used to control and turns to and the radius when turning round, and is similar to rudder commonly used in the boats and ships, and differential and synchronous two kinds of modes are arranged.
In conjunction with Fig. 1-Fig. 5 control policy of the present invention is described.This structure hydrofoil catamaran not only can be realized direct course at a high speed, can also carry out the fast speed gyroscopic movement.Specifically, can realize control on pitching/heave, four degree of freedom of revolution/heel.
When line navigation, when having very large wave to disturb, hydrofoil catamaran has violent heave movement, when the rising displacement of hydrofoil catamaran and ascending velocity are larger, can reduce synchronously the angle of wing flap 7,8 and 14,15 simultaneously, and the variable quantity of heave is diminished; On the contrary, if hydrofoil catamaran is in the peak of wave, have the possibility of quick tenesmus, at this moment, then need to increase synchronously the angle of wing flap 7,8 and 14,15.Same wave can cause the pitching motion that hydrofoil catamaran is violent, when pitching that bow makes progress, need to reduce synchronously the angle of wing flap 7,8, increases simultaneously the angle of wing flap 14,15; On the contrary, when bow turns, need to increase synchronously the angle of the smaller or inner piece on the right side of a Chinese garment which buttons on the right wing 7,8 downwards, reduce simultaneously the angle of wing flap 14,15.Because when control pitching and heave movement, the corner of wing flap is opposite, so need to coordinate the corner of control wing flap, just can reach desirable effect.
When carrying out gyroscopic movement, exist wave to disturb when supposing gyroscopic movement, this moment, heel and the pitching/heave of hydrofoil catamaran existed simultaneously, the coordination control of wing flap and the post wing before and after this just needs.Suppose that ship is to turn round left, at first two post wings all need to have corner to the right, and the post wing angle in left side is a bit larger tham the post wing angle on right side, and maximum moment of gyration can be provided, and fast speed turns round.At this moment, because heel is more serious, should be the corner that increases wing flap 8,15, reduce the corner of wing flap 7,14, and may should coordinate as required to control the wing flap corner this moment with the variation of pitching/heave, realize pitching/heave, revolution/heel coordination control.This front and back wing flap is controlled respectively revolution/heel, the method for pitching/heave movement, and efficient is high, accurately, and also more convenient.
