Therefore, in order to learn the operation principle of rocket launching, be necessary the rocket making a kind of teaching aid or toy-type, making under its condition of launching in low cost just can the operation principle of abundant rocket launching analog, allow student and child at the physical principle of the process learning rocket launching played, arouse the interest in study, also can strengthen recreational.
Summary of the invention
The technical problem to be solved in the present invention overcomes the deficiencies in the prior art exactly, a kind of ingenious application Rafael nozzle operation principle is provided to carry out teaching aid or the toy-type rocket of air water injection, this rocket has the advantages that structure is simple, implementation cost is low, is particularly suitable for doing teaching aid or toy use.
For overcoming the deficiencies in the prior art, the present invention takes following technical scheme:
Foaming bung with Horizontal identification launches an one empennage-type churning water rocket, comprises launching tube and rocket body, it is characterized in that: launching tube is by triangle launcher fixed support, and launcher is provided with Horizontal identification; Launching tube top is provided with the transmitting lid of threaded engagement, launches in lid and has taper foaming bung, and screw transmitting lid and can realize sealing, when launching cylinder pressure and being enough large, taper foaming bung can quick-fried spray out, and repeatedly can assemble use; Launching tube bottom is provided with valve input compressed-air, is provided with centre of location stake and carries out nested type centralized positioning to the bottom spout of inserting rocket bottom launching tube; Plastic cement spheroid is arranged at rocket body top, microgap Air-tight piston formula can be carried out slide in smooth launching tube, plastic cement spheroid upper middle position has through hole and check valve sheet, through hole can realize air inlet and pour water, check valve sheet can be carried out unidirectional control and be realized closing sealing, similar basketball valve under positive pressure; The firm airtight connection outer tube in spheroid bottom, outer tube has center tracheae, and center tracheae inserts in spheroid, and center tracheae Minimal Tension is closed and realized sealing and be connected by the contraction elasticity of spheroid through hole plastic cement, can conducting when having an interior pressure; Outer tube bottom is that inwall first expands the air water jet pipe reduced again, air water jet pipe water nozzle is provided with rotary fluid, the inwall of rotary fluid is carved with helicla flute, tracheae lower end, center is conical, and to be provided with aperture be compressed air spout, the coaxial embedding outer tube of center tracheae non-fully contact, formed in outer tube and between central tube and bore tubular throttling aquaporin and daraf(reciprocal of farad) that conical surface expansion chambers, your conical surface expansion chambers of daraf(reciprocal of farad) is the mixing chamber that compressed air and pressure (hydraulic) water enter simultaneously, and gas-water mixture is by the bottom spout high velocity jet of rocket; The outer wall of outer tube bottom is provided with one empennage.
Altitude scale is provided with in described spheroid.
The present invention mainly carries out the optimal design of air water rocket by flexible Application Rafael nozzle operation principle, can fly get Geng Gao to realize air water rocket.
The operation principle of Rafael nozzle is such: the jet pipe of band trunnion, classical hydrodynamics is followed when Compressed Gas first progressively enters the narrowest and small throat's process by the pipe position that cross section is larger, cross section diminish flow velocity increase, resistance also significantly increases sharply, form the flowing of a kind of gas throttling, but the convergent divergent channel part that Compressed Gas progressively expands by entering cross section after throat's smallest cross-sectional, due to the decompressional expansion of Compressed Gas, gas no longer follows Classical Fluid Mechanics, but can be sprayed by convergent divergent channel with very high speed, if compression pressure is enough high and nozzle structure is reasonable, gas can spray from spout with supersonic speed.Rafael nozzle operation principle is applied to jet airplane and rocket, significantly improves efficiency and the power of jet engine, achieves space flight, the leaping of science and technology of aviation.
The present invention is that the operation principle of application Rafael nozzle carries out mixing wastewater with air high velocity jet, and can realize the most rational Conversion of Energy, make the very high of rocket flight, its course of work is such:
1, the spheroid of rocket body is poured into suitable quantity of water, water level is the highest, and to be no more than center tracheae suitable for reading, assembles and adjust perpendicularity just can connect valve and carry out compressed-air actuated input, now progressively can be full of compressed air in launching tube and rocket body;
2, when pressure increase is to when making that taper foaming bung is quick-fried to be sprayed out, the air pressure of rocket spheroid front end reduces to atmospheric pressure instantaneously, and spheroid bottom compressed air is then rapid as shell is launched, by rocket body outburst injection, valve block can be closed rapidly under interior pressure effect, realizes one-level and launches;
3, one empennage can control rocket stabilization flight, spheroid compressed air is by the ejection of tracheae lower end, center spout simultaneously, retaining in compressed air-driven spheroid enters outer tube by elasticity open gaps between spheroid and center tracheae and carries downwards, mixing chamber is entered from lower end cone tubular throttling passage eddy flow by rotary fluid, due to daraf(reciprocal of farad) that effect, compressed air expansion driven mixing wastewater with air is also spouting from spout at a high speed, obtain powerful recoil power, the second motive force realizing water rocket sprays, and makes it to fly get Geng Gao.
In order to rocket body compressed air potential energy is converted into injection power most effectively, it is optimal state that air water has sprayed simultaneously; Pipe throttle can make air water optimal proportion mixing jetting, can realize peak efficiency and strong impetus is flown, and supports to fly get Geng Gao, farther.
Compared with prior art, beneficial effect of the present invention is also:
Ingenious achieve pressure launch with one stage of compression air launch flight; The ingenious two-stage ignition flight simulating rocket of two-stage injection flight; Also ingeniously merge classical Rafael nozzle principle to promote experimental level and to promote student to the perception of science, make rocket fly get Geng Gao, farther; Foaming bung moderate pressure, is applicable to toy and teaching aid uses, and does not have potential safety hazard.
Apparatus of the present invention structure is simple, reliable, ingenious, cost is low, has good operability and Science Explorations intelligence development characteristic, is the teaching aid and toy that practicality is very strong.
