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 in rocket body with can progressively be full of compressed air；
2nd, when pressure, which rises to, opens the quick-fried spraying of taper foaming bung, the air pressure moment of rocket spheroid front end is reduced to air
Pressure, spheroid bottom compressed air then rapidly as shell transmitting are the same, rocket body are broken out and projected, valve block is in the case where internal pressure acts on
It can rapidly close, realize that one-level is launched；
3rd, integral empennage can control rocket stabilization to fly, while spheroid compressed air passes through center tracheae lower end spout
Spray, the water storage in compressed air-driven spheroid is downward into outer tube by elastic open gaps between spheroid and center tracheae
Conveying, enters mixing chamber by rotary fluid from lower end cone cylinder shape throttling passage eddy flow, due to daraf(reciprocal of farad) that effect, compressed air expansion
Drive mixing wastewater with air and high speed is spouting from spout, obtain strength recoil power, realize the second motive force injection of water rocket, make
Fly get Geng Gao.
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, supports to fly
It is higher, farther.
Compared with prior art, beneficial effects of the present invention also reside 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；Foaming bung moderate pressure, it is adapted to toy and teaching aid to use, without potential safety hazard.
Apparatus of the present invention are simple in construction, reliable, ingenious, cost is low, have good operability and Science Explorations intelligence development
Characteristic, it is practicality very strong teaching aid and toy.
