Abstract
It the utility model is related to science popularization appliance for teaching, and in particular to a kind of science popularization rocket model.In daily teaching and science popularization process, there are following two problems in the type of drive of science popularization rocket model：The mode that the mode of violent chemical change produces substantial amounts of gas is difficult to control, it is higher while also dangerous using process to consume larger and cost；Implementing the anti-driving power deficiency that pushes away using compressed air can not be lasting.It is directed to this, the utility model installs a liquid carbon dioxide storage tank in the inside of model rocket, drastically gasified using liquid carbon dioxide and produce substantial amounts of carbon dioxide to reach the purpose of driving model rocket, a kind of science popularization provided by the utility model rocket model driving force foot, duration length and caused gas are nontoxic non-combustible, it is reliable using process safety, liquid carbon dioxide is cheap and is easily made, and use cost is relatively low.
Description
Technical field
It the utility model is related to science popularization appliance for teaching, and in particular to a kind of science popularization rocket model.
Background technology
The principle of the aviation applications of rocket recoil, they are all to act on by spraying the recoil of air-flow and obtain huge speed
's.According to Newton's third law：Active force and reaction force between two objects, on the same line, equal in magnitude, direction
Conversely.Rocket sprays the gas of HTHP backward with great jet power, high speed after lighting, high temperature and high pressure gas with
The arrow of getting angry of pushing of opposite direction travels forward.
Rocket recoil can have different form of presentations, but various statements is substantially identical, and common science popularization audient is come
Say that degree-of-difficulty factor is larger.In daily teaching and science popularization process, there is science popularization teaching apparatus made of many utilization backsurging principles.
These devices typically produce substantial amounts of gas to reach the purpose of recoil using the mode of violent chemical change.But use drastically
The method of chemical reaction is difficult to control, it is higher to consume larger and cost, while also dangerous using process.There are some uses in addition
Compressed air implements the equipment of rocket model recoil pull, although can accomplish low consumption safety, the compression that model carries
The thrust that gas provides is limited, can not persistently promote, it is therefore desirable to designs a kind of safety, low consumption, rocket section lasting, thrust is big
It is general to use rocket model.
The content of the invention
The utility model purpose is to provide a kind of science popularization rocket model, can allow science popularization audient direct feel to rocket
The effect of recoil effect.
In order to reach above-mentioned technique effect, the technical solution of the utility model is：A kind of science popularization rocket model, including fire
Arrow, rocket body, arrow tail, rocket head are connected to the top of rocket body, and arrow tail is connected to the bottom of rocket body, is also provided with described arrow tail
Spray-hole, in addition to liquid carbon dioxide storage tank, described liquid carbon dioxide storage tank is provided with jet exit, described
Liquid carbon dioxide storage tank is placed on inside rocket body, and described jet exit is connected on spray-hole.
Preferably, liquid carbon dioxide storage tank described in the utility model is also provided with an air exit, rocket body it is upper
End is also provided with a gas passage, and the port of export of gas passage is also equipped with a spring catch；One side hinge of described rocket head
The upper end of rocket body is connected on, the another side of rocket head is fixed on rocket body by spring catch；Described spring catch is pressurized can be from gas
Passage, which stretches out, simultaneously seals gas passage, and atmospheric pressure state spring catch can retract gas passage；It is provided with the top of described rocket body
Land pack, and parachute coating is covered in rocket head；Described air exit is connected with gas passage.
It is of the present utility model to have technical effect that：
1 in the utility model rocket body inside set liquid carbon dioxide storage tank, stored using liquid carbon dioxide
The carbon dioxide of tank memory storage, in use, the carbon dioxide drastically to gasify produces recoil active force by spray-hole.Gasification
More persistently, and thrust is larger, and carbon dioxide is nontoxic non-combustible, thus safer using process.
Before 2 are gasified totally, higher pressure can be kept inside liquid carbon dioxide storage tank, in the presence of the pressure,
Spring catch is stretched out and can keep the sealing of gas passage, and under spring catch stretching state, rocket head is locked on rocket body；Work as consumption
To the greatest extent, when the pressure inside liquid carbon dioxide storage tank is insufficiently resistant to spring catch screen resilience, in spring catch retraction gas passage.
Now model rocket thrust exhausts, and in dropping process, rocket head can open around pin joint, and parachute can nature opening drive
Model rocket landing ground.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model；
Embodiment：
Specific embodiment of the present utility model is described in detail below.It is it should be appreciated that described herein
Embodiment is merely to illustrate and explained the utility model, is not limited to the utility model.
Referring to the drawings 1, a kind of science popularization rocket model, including rocket head 100, rocket body 200, arrow tail 300, rocket head 100
The top of rocket body 200 is connected to, arrow tail 300 is connected to the bottom of rocket body 200, spray-hole is also provided with described arrow tail 300
301, it is characterised in that：Also include liquid carbon dioxide storage tank 400, described liquid carbon dioxide storage tank 400 is provided with
Jet exit 401, described liquid carbon dioxide storage tank 400 are placed on inside rocket body 200, and described jet exit 401 connects
It is connected on spray-hole 301.
When model rocket is run, the meeting in liquid carbon dioxide storage tank 400 is drastically gasified, and carbon dioxide passes through spray
Exit wound of bullet 401 reaches spray-hole 301, rapidly sprays, and produces larger propulsive thrust and promotes model rocket flight forward.
Because model rocket has certain weight, while model rocket lift-off height is higher, and it is final to there is model rocket
Threaten ground staff to obtain risk safely when falling, while can also break model rocket housing.Preferably,
Liquid carbon dioxide storage tank 400 described in the utility model is also provided with an air exit 402, rocket body 200
Upper end is also provided with a gas passage 201, and the port of export of gas passage 201 is also equipped with a spring catch 202；Described rocket
