Description
Technical field
The present invention relates to a kind of teaching aid or toy, refer specifically to launch streamline empennage-type direct-injection extreme misery with manometric rubber stopper
Arrow.
Background technology
Rocket is the product of development in science and technology to a certain extent, and it goes out the history that there is now up to a hundred years, and the transmitting of rocket is included
Sufficiently complex dynamic process, is also giving full play to and applying for physical principle.
Therefore, in order to learn the operation principle of rocket launching, it is necessary to make the rocket of a kind of teaching aid or toy-type, make it
Under conditions of low cost transmitting just can abundant rocket launching analog operation principle, allow student and child during object for appreciation
Learn the physical principle of rocket launching, excite learning interest, can also strengthen recreational.
The content of the invention
The technical problem to be solved in the present invention is exactly to overcome the deficiencies in the prior art to be sprayed there is provided a kind of ingenious application daraf(reciprocal of farad) that
Pipe operation principle carries out the teaching aid or toy-type rocket of air water injection, and this rocket has the low spy of simple in construction, implementation cost
Point, is particularly suitable for making teaching aid or toy is used.
To overcome the deficiencies in the prior art, the present invention takes following technical scheme：
A kind of to launch streamline empennage-type direct-injection water rocket, including launching tube and rocket body with manometric rubber stopper, it is special
Levy and be：Launching tube top, which is provided with the transmitting lid of screw thread cooperation, transmitting lid, cone rubber plug, screws transmitting lid achievable close
Envelope, when launch cylinder pressure it is sufficiently large when, cone rubber plug can be sprayed open with quick-fried, and can repeatedly be assembled and used；Launching tube inwall
Smooth and be connected with pressure gauge, bottom inputs compressed air provided with valve, and launching tube bottom is provided with centre of location stake to inserting fire
The bottom spout of arrow carries out nested type centralized positioning；Plastic cement spheroid is arranged at rocket body top, can be carried out in smooth launching tube
Microgap Air-tight piston formula is slided, and plastic cement spheroid upper middle position has through hole and check valve sheet, and through hole can realize air inlet
With pouring water, check valve sheet can carry out unidirectionally controlled and closing sealing, similar basketball valve are realized under positive pressure；Spheroid
The firm airtight connection outer tube in bottom, outer tube has in center tracheae, center tracheae insertion spheroid, spheroid through hole plastic cement
Contraction elasticity by center tracheae Minimal Tension close realize sealing linking, having can turn on during internal pressure；Outer tube bottom is that inwall is first
The air water jet pipe reduced again is expanded, center tracheae lower end is cone, and is compressed air spout provided with aperture, and center tracheae is non-
The coaxially embedded outer tube of full-contact, forms cone cylinder shape throttling aquaporin and daraf(reciprocal of farad) that curved surface expansion between central tube in outer tube
Room, your curved surface expansion chambers of daraf(reciprocal of farad) are the mixing chamber that compressed air enters with pressure (hydraulic) water simultaneously, and gas-water mixture passes through under rocket
Portion's spout sprays at a high speed；The outer wall of outer tube bottom is provided with streamline empennage.
The launching tube is fixed by triangle launcher and supported.
The present invention mainly carries out the optimization design of air water rocket by flexible Application Rafael nozzle operation principle, with
Realize that air water rocket can fly get Geng Gao.
The operation principle of Rafael nozzle is such：Jet pipe with trunnion, when compressed gas is first by the larger pipe in section
Position step into most narrow and small throat's process follow classics hydrodynamics, section diminish flow velocity increase, resistance it is also significantly fast
Speed increase, forms a kind of gas throttling flowing, but compressed gas is by entering the expansion that section progressively expands after throat's smallest cross-sectional
Tube portion is opened, due to the decompressional expansion of compressed gas, gas no longer follows Classical Fluid Mechanics, but can be with very high speed
Sprayed by expansion pipe, if compression pressure is sufficiently high and nozzle structure is reasonable, gas can be sprayed with supersonic speed from spout.Draw
Fa Er jet pipes operation principle is applied to jet airplane and rocket, greatly improves the efficiency and power of jet engine, realizes
Space flight, science and technology of aviation are leapt.
The present invention is to carry out mixing wastewater with air using the operation principle of Rafael nozzle to spray at a high speed, and most rational energy can be achieved
Amount conversion, makes the very high of rocket flight, its course of work is such：
1st, the spheroid of rocket body is poured into suitable quantity of water, water level not more than center tracheae is suitable for reading, assembles and adjusts
Perpendicularity is compressed the input of air with regard to that can connect valve, and now launching tube is with can progressively be full of compressed air in rocket body；
2nd, when pressure, which rises to, makes that cone rubber plug is quick-fried to be sprayed out, the air pressure moment of rocket spheroid front end is reduced to air
Pressure, spheroid bottom compressed air then the rapid transmitting such as shell, rocket body is broken out and projected, and valve block is under internal pressure effect
It can rapidly close, realize that one-level is launched；
3rd, streamline empennage can control rocket stabilization to fly, while spheroid compressed air passes through center tracheae lower end spout
Spray, it is downward that the retaining in compressed air-driven spheroid enters outer tube by elastic open gaps between spheroid and center tracheae
Conveying, finally enters mixing chamber together from lower end cone cylinder shape throttling passage, and due to daraf(reciprocal of farad) that effect, compressed air expansion drive is taken offence
Water mixing is simultaneously spouting from spout at a high speed, obtains strength recoil power, realizes the second motive force injection of water rocket, is allowed to winged
It is higher.
In order to which rocket body compressed air potential energy is most effectively converted into injection power, it is optimal that air water has sprayed simultaneously
State；Pipe throttle can make air water optimal proportion mixing jetting, it is possible to achieve peak efficiency is flown with strong impetus, support to fly
It is higher, farther.
Compared with prior art, beneficial effects of the present invention are also resided in：
It is ingenious to realize pressure transmitting and the ejection flight of one stage of compression air；The ingenious rocket of simulating of two-stage injection flight
Two-stage ignition flies；It is also ingenious to have merged classical Rafael nozzle principle to lift experimental level and lifting student to science
Come to realize, rocket is flown get Geng Gao, farther；Streamline empennage also has spinfunction；To rubber stopper by dipping in water or smearing suds
Ejection frictional force can be changed to adjust the quick-fried power of spraying by being lubricated.
Apparatus of the present invention are simple in construction, reliable, ingenious, cost is low, with good operability and Science Explorations intelligence development
Characteristic, is practicality very strong teaching aid and toy.
