The specific embodiment
Shown in Fig. 1-4, controllable hydrofoil displacement boat of the present invention comprises hull 1, and the horizontal left and right sides of hull 1 is the ship side of a ship, laterally on the ship side of a ship of the left and right sides, 3, two grooved tracks 3 of a grooved tracks is respectively set symmetrical.Grooved tracks 3 is along longitudinal layout of hull 1, and the center of grooved tracks 3 is centers of gravity of the ship side of a ship.At the interior installation hydraulic actuator 9 of grooved tracks 3.
Referring to Fig. 3, hydraulic actuator 9 is fixed in grooved tracks 3, with shrouding 7, hydraulic actuator 9 is sealed in grooved tracks 3,, with screw 6, shrouding 7 is fixed on hull 1 meanwhile.Hydraulic actuator 9 has hydraulic push rod 8, and the top of hydraulic push rod 8 is longitudinally stretched out outside shrouding 7 and is fixedly connected with hydrofoil system.Hydrofoil system comprises hydrofoil 2, electrical motor 5 and airtight watertight box 10, hydrofoil 2 is shallow immersion wings, the top of hydraulic push rod 8 is fixedly connected with watertight box 10, watertight box 10 is positioned at grooved tracks 3 and can longitudinally slidably reciprocating along grooved tracks 3, at the interior installation electrical motor 5 of watertight box 10, the output shaft 4 of electrical motor 5 is perpendicular to the ship side of a ship and stretch out outside grooved tracks 3, on the outer end of output shaft 4, be fixedly connected with hydrofoil 2, like this, the watertight box 10 in the 8 promotion hydrofoil systems of the hydraulic push rod in hydraulic actuator 9 is along grooved tracks 3 longitudinal movements and location.Electrical motor 5 drive hydrofoils 2 can be in rotational plane Arbitrary Rotation and location, rotational plane and turning cylinder 4 are perpendicular and be parallel to the ship side of a ship.
At grooved tracks 3 outer setting hydraulic control systems 13 and central process unit (PLC) 11, hydraulic actuator 9 is by wire 14 connecting fluid pressure control systems 13, and hydraulic control system 13 is connected central process unit 11 by wire 12 respectively with electrical motor 5.By central process unit 11, send instruction, realize the control to hydraulic control system 13 and electrical motor 5, and then realize the change angle of attack motion longitudinally and in horizontal surface to hydrofoil 2.
When glider of the present invention remains static, hydrofoil 2 is direction placement perpendicular to level, and draws near topside, can not affect and berth.
Before glider enters sliding state, central process unit 11 sends instruction and controls electrical motor 5 drive hydrofoil 2 rotations, and hydrofoil 2 is rotated to horizontal by suitable angle, is adjusted to the best angle of attack that becomes, to produce larger dynamic lift and moment.Central process unit 11 is controlled hydraulic control system 13 simultaneously makes the hydraulic push rod 8 promotion hydrofoils 2 in hydraulic actuator 9 move to stem direction, make glider start to obtain a larger moment, make glider lift head, increase planing surface, accelerated slip ship is crossed drag hump, helps glider and enters fast sliding state.As shown in Figure 1, when hydrofoil 2 is when necessarily becoming angle of attack with the glider high speed speed of a ship or plane, hydrofoil 2 produces a dynamic lift, and when hydrofoil 2 move to ship bow, glider can produce an anticlockwise moment, makes glider lift head, and acceleration enters sliding state.
When glider is during in sliding state, hydrofoil 2 moves near center-of-gravity position, makes to become angle of attack and horizontal plane angle and approaches 0 degree, can reach and promote the stability of glider sliding state and the function of direct route ability.
After glider enters sliding state, by regulating the position of hydrofoil 2 in longitudinal fluting track 3 and change angle of attack to resist external load.As shown in Figure 1, take ever-increasing wind speed as example, when wind speed increases, glider running resistance increases, under the certain prerequisite of main frame horsepower output, the glider speed of a ship or plane declines, there is sinkage in hull 1, by adjusting the change angle of attack of hydrofoil 2, produce dynamic lift and make up because speed of a ship or plane hull 1 dynamic lift causing that declines reduces value, glider just there will not be sinkage, hydrofoil 2 is shifted to ship afterbody simultaneously, make glider obtain a clockwise moment, be used for offsetting the added value of the anticlockwise moment causing due to speed of a ship or plane decline, thereby guarantee the stationarity of glider navigation.The existence of hydrofoil 2, is equivalent to have increased ship wide, useful to the course stability of glider.
When the glider navigating by water at a high speed suddenly stops and slows down, regulate the change angle of attack of hydrofoil 2 to become 90 degree angles, hydrofoil 2 blocks water and produces larger resistance, increases the braking potential of glider, avoids glider ship draught forward serious, contributes to suddenly stop and slow down.
Above-mentioned state while being all glider line navigation, hydrofoil 2 synchronization regulation of two topsides of hull 1.When glider turns round, can pass through the asynchronous adjusting of 1 liang of topside hydrofoil 2 of hull, realize corresponding function, make the change angle of attack of a side hydrofoil 2 produce larger resistance, and the change angle of attack of an other side hydrofoil 2 produces compared with slight drag, thereby produce a moment of gyration, play and accelerate rotating effect, weaken sidesway phenomenon.When glider turns round, by the asynchronous adjusting increase moment of gyration of two hydrofoils 2, contribute to improve the turnability of glider.As shown in Figure 1, take glider right-hand rotation as example, it is 90 degree left and right that the hydrofoil 2 of starboard side regulates change angle of attack and horizontal plane angle, and starboard side hydrofoil 2 blocks water and produces larger resistance, and 2 adjustings of port side hydrofoil become angle of attack and horizontal plane angle is about 0 degree, current can pass through port side hydrofoil 2 smoothly, produce less resistance, glider both sides are subject to force unbalance, and right side resistance is greater than left side, thereby produced a right-hand rotation moment, made glider right-hand rotation.The left rotating method of glider is contrary with right-hand rotation, increase the change angle of attack of hull left side hydrofoil 2, be adjusted near 90 degree, the change angle of attack of right side hydrofoil 2 is adjusted near 0 degree, the resistance that left side hydrofoil 2 produces is far longer than right side hydrofoil 2, therefore produce a left moment of gyration, glider produces left gyroscopic movement.
