Description
Technical field
The present invention relates to water rocket, specifically a kind of air resistance that utilizes is realized controlling powerful external force control type two-stage water toy rocket with weak power.
Background technology
Water rocket is that to utilize common plastic bottle (as Coke bottle) be material, take Newton third law (acting force and reacting force) as principle, with air pressure and the water environmental protection rocket simulated flight device as power.
Water rocket launching is a kind of extracurricular scientific and technological activities of rocket launching analog process, and its active procedure stimulates but be also very safe, be teach through lively activities, the higher activity to popularize scientific knowledge of integrated practice high in technological content, that deeply liked by numerous teenagers.
Existing two-stage water toy rocket is to utilize separation vessel between adjacent two-stage rocket body and the releasing means of inner aqueous vapor to carry out the second-order separation.Chinese patent CN2573037Y discloses a kind of two-stage water toy rocket, it comprises tail nozzle, one-level rocket body, separation vessel and secondary rocket body, the one-level rocket body is that two ends are with the long cylindrical body of narrow tube threaded connector, the tail nozzle is screwed on a pipe screw joint of one-level rocket body by the internal thread of a side, separation vessel is screwed on another pipe screw joint of one-level rocket body by the internal thread of an end, and the other end inserts in the socket of two-stage water toy rocket body bottom.This water rocket has open defect in security with above controllability, and abundant not to the power utilization of one-level rocket body, thereby affects firing altitude.
Summary of the invention
The objective of the invention is for overcoming the deficiencies in the prior art, and provide a kind of simple in structure, with low cost, and can utilize the stable Novel two-stage water rocket that separates of the ingenious realization of air resistance.
The technical scheme that realizes the object of the invention is:
A kind of Novel two-stage water rocket that utilizes air resistance to separate, comprise one-level rocket body, secondary rocket body, parachute and launcher, unlike the prior art be: be connected by separation control between one-level rocket body and secondary rocket body, be provided with to separate bottom the one-level rocket body and control the wing, separate to control the wing yard affixed by hanging on wire rope and separation control, set up anchor switch, rain glass and directed guide rail on launcher.
Described separation control comprise hang code, connect clasp, spring, the directed post of spring, band, valve inside, rubber stopper be connected with connection fastening support ring hang code and be connected the clasp connection, the directed column sleeve of spring and spring connects, the directed post of spring connects with groove on being connected the fastening support ring, valve inside passes rubber stopper and is connected with the one-level rocket body, and band passes and connects fastening support ring and secondary rocket body snapping.
It is a pair of laborsaving lever that the wing is controlled in described separation, one end and the wire loop snapping that is fixed on the one-level rocket body, and rotate around it.
Described anchor switch comprises angle bar, rubber plug and snap close, and snap close is provided with siphunculus by window catch and angle bar snapping in rubber plug, and the bottleneck of one-level rocket body is connected with rubber plug.
Described rain glass is prior art.
Described directed guide rail is prior art
The principle of work of this water rocket is: adopt external force control to trigger the mode of separating, utilized dexterously first order water rocket to accelerate to act in uphill process the air resistance that separates on the control wing and controlled separation.When first order water rocket rises to certain altitude and decelerates to a certain degree, second level water rocket just breaks away from one-stage rocket under the effect of atmospheric pressure in spring force and bottle, thereby realize the second-order separation, accelerate for the second time, break through firing altitude (firing altitude can reach 100 meters left and right), rocket launching analog process more true to nature with this.Retaining valve has been adopted in the secondary junction, has realized gas one-way conduction from lower to upper, thereby makes between the two-stage water rocket draught head less, has guaranteed the power of the second level, simultaneously also convenient inflation.
Advantage of the present invention is:
(1) adopt external force control to trigger the mode of separating, utilized dexterously first order water rocket to accelerate to act in uphill process the air resistance that separates on the control wing and controlled separation, take full advantage of the thrust of one-level rocket body, and between the two-stage rocket body, draught head is very little.
(2) multinomial measure improves controllability and security: adopt anchor switch to control the emission of water rocket, extend gas-filled tube, rain glass, directed guide rail and parachute etc. have been installed, the controllability and the security that have greatly improved water rocket;
(3) simple in structure, easy to operate, and safety and environmental protection, stable performance.
