Abstract
The side pushing towing-ship has two right-angled propellers mounted, one in prow and one in poop and thus side pushing operation function. When some ship is to off land, the towing-ship is inserted into the gap between the prow of the ship and the pier, two propellers work simultaneously to produce pushing force perpendicular to the main plane of the longitudinal symmetrical towing ship axis, and the pushing force acts on the prow of the ship to push it off land. The towing-ship has great pushing force, and can turn flexibly in water.
Description
Technical field
The present invention relates to aircraft component, particularly a kind of porose loose-leaf type flapping-wing aircraft wing.
Background technology
The mankind are five-star intelligent life entities on the earth.People have created the human civilization of today with industrious both hands for thousands of years.People can produce aircraft travels around the world mankind's sky that flies up into the sky, and also can produce the rocket delivery mankind and climb up lunar exploration universe secret.But the wing that people can fly on regretting and oneself not having to grow as bird, lightheartedly aloft circles in the air as insect.So it is human dream for thousands of years that the people can fly as bird.In order to develop the wing that can fly, do not know to have how many people to drop into energy throughout one's life and sweat, do not realize this dream but also produce desirable flapping-wing aircraft so far.The a great problem of flapping wing will reduce its windage exactly as far as possible when it is upwards fluttered, then opposite when fluttering downwards.The distortion of its wing still can not address the above problem when merely imitation flight animal flew, and made body can not get enough lift.
We have consulted a large amount of data, only find the machine fly of their development that research group of Univ California-Berkeley showed in 2002, this intelligence machine as the fly size can imitate the artificial wing of fly wing motion, per second is flapped 150 times, however, they still can not allow the machine fly fly up (seeing A14 version in " Shandong evening paper " on October 30th, 2002).
Summary of the invention
The objective of the invention is just to provide a kind of when last pouncing on resistance little, the big porose loose-leaf type flapping-wing aircraft wing of resistance when pouncing on down, to produce various flapping-wing aircrafts and the aircraft that is fit to human flight as early as possible, plug a gap, and be used for aspects such as national defense and military, traffic and sea rescue, field study, forest fire protection rapidly, accelerate human sciences's progress.
For achieving the above object, the present invention takes following technical measures: comprise the wing framework, the wind hole is arranged on this framework, be provided with movable leaf on each wind hole.
Described wind hole has a plurality of and serial arrangement, and described movable leaf is made by elastic deformable material, and the one end is connected with the framework on limit, wind hole.
Described wind hole has a plurality of and serial arrangement, and one side of described movable leaf is hinged with wind hole frame one side, and is provided with limiting stopper at hinging place, makes movable leaf pendulum angle less than 90 °.
Described wind hole is arranged side by side in pairs, and a pair of lambdoid movable leaf that is is hinged on the framework between them.
A plurality of orders wind hole is side by side arranged on the described framework, and described movable leaf constitutes and the cooresponding framed structure in above-mentioned wind hole, and with wing framework overlaid, sliding block joint between the two.
Described movable leaf has the axle rotation to pass framework, and movable leaf shape and cross section, wind hole match to merge and be a bit larger tham the wind hole.
Described wind hole is made of a plurality of fan-shaped circular holes of forming, and described movable leaf is made up of the fan-shaped leaf that a plurality of and above-mentioned sector wind hole cooperates, and their tail end interconnects and is rotationally connected with center, wind hole.
Many ventilation wind hole is arranged on the wing of the present invention, and wind has moving vane in the hole.It is open to lift Shi Fengkong on wing, and mass air flow reduces the resistance of air to flapping wing by the wind hole.When wing during to lower swing flap close the wind hole, increase the resistance of air to flapping wing, with antagonistic force fuselage is risen.The present invention can agitate direction or/and change wing by wing is rotated to an angle, and obtains the power that advances or retreat when producing lift; And by adjusting frequency or the dynamics difference that both wings are fluttered, realize turning round.

The specific embodiment
Referring to Fig. 1, the present invention includes wing framework 1, on this framework 1, wind hole 2 is arranged, on each wind hole 2, be provided with movable leaf 4.The framework of whole wing can be around oscillating axle 3 swings (fluttering).
The wind hole 2 of this embodiment has a plurality of and serial arrangement, and described movable leaf 4 is made by elastic deformable material, and the one end is connected with the framework 2 on limit, wind hole.When wing was upwards fluttered, elastomeric movable leaf 4 opened downwards under the effect of air-flow, and air-flow can pass through wind hole 2 smoothly.And movable leaf 4 is by the air-flow closure when wing is fluttered downwards, and wind hole 2 is closed, and increases resistance.
Referring to Fig. 2, the movable leaf 4 of this embodiment is hard sheets, and its one side is hinged with a side of wind hole frame 1, and is provided with limiting stopper 5 at hinging place, makes movable leaf 4 pendulum angles less than 90 °.
Referring to Fig. 3, the wind hole 2 of this embodiment is arranged side by side in pairs, and a pair of lambdoid movable leaf 4 that is is hinged on the framework 11 between them.
Referring to Fig. 4 and Fig. 5, a plurality of orders wind hole 2 is side by side arranged on the framework of this embodiment, described movable leaf 4 constitutes and above-mentioned wind hole 2 cooresponding framed structures, and with wing framework 1 overlaid, chute 5 sliding block joints by two edges between the two.
Referring to Fig. 6 and Fig. 7, there is axle 41 to rotate on the movable leaf 4 of this embodiment and passes framework 1, the cross section in movable leaf 4 shapes and wind hole 2 matches to merge and is a bit larger tham the wind hole.Rotate 90 ° of adjustings that realize windage by movable leaf.
Referring to Fig. 8, the wind hole 2 of this embodiment is made of a plurality of fan-shaped circular holes of forming, and described movable leaf 4 is made up of the fan-shaped leaf that a plurality of and above-mentioned sector wind hole cooperates, and their tail end interconnects and is rotationally connected with wind hole center shaft 41.Realize the adjusting of windage by the rotation of movable leaf 4.
