Description
Technical field
The present invention relates to model rocket, particularly to the electromotor of model rocket.
Background technology
Current most of goods model rocket engine is all to be main as propellant using black powder, and black powder has higher
Impact sensitivity, friction sensitivity and electrostatic sensitivity, there is certain danger when shipping storage, and during the work of such electromotor
The thermal-flame surrounding objects that easily ignites of ejection causes the accident, and has sulfur dioxide, nitrogen oxides etc. to be harmful in discharged gas
Material, safety and the feature of environmental protection are poor.
Summary of the invention
It is an object of the invention to: providing one that prior art can be overcome not enough, more safe and environment-friendly model rocket is sent out
Motivation.
The technical scheme is that a kind of model rocket engine, it includes: by storage tank top cover, storage tank housing and spray
The housing of pipe composition；It is characterized in that: further comprising: be located at the electronic ignition head of described enclosure interior top dead center position, be trapped among
The catalyst sprinkler of described electronic ignition head periphery and catalyst granules, encapsulate described catalyst granules from below when normality
Block, be located in described enclosure interior lower position for closing the storage tank bottom of described storage tank housing, be positioned at the bottom of described storage tank
The propellant entrance at lid center, covers the diaphragm of described propellant entrance, is encapsulated in the working media of described storage tank enclosure interior,
Catalyst gauze thrust chamber between described storage tank bottom and described jet pipe.
During the work of this model rocket engine, electronic ignition head is received signal of telecommunication after-fire, is produced a small amount of gas by block
Back down so that catalyst granules is sprinkled in the propellant in storage tank, catalytic decomposition propellant, produce pressure by propellant entrance
Diaphragm backs down, and propellant is pressed into catalyst gauze thrust chamber, is allowed to be fully contacted with catalyst gauze, and propellant is by after catalytic decomposition
Produce gas from jet pipe Accelerating Removal, generation power.
Safety of the present invention is good, and operating temperature is low, sprays without thermal-flame, discharged gas clean environment firendly, the water of discharge
Steam air around condenses rapidly and produces water smoke, have and well draw cigarette effect.This kind of model rocket engine is permissible
On being widely used in science popularization as dynamical system, educating and entertain.
Accompanying drawing explanation
Fig. 1 is present configuration figure.

Fill the block (3) of described catalyst granules (2), be located in described enclosure interior lower position for closing described storage tank housing (5)
Storage tank bottom (6), be positioned at the propellant entrance (8) at described storage tank bottom (6) center, cover described propellant entrance (8)
Diaphragm (7), is encapsulated in the working media that described storage tank housing (5) is internal, is positioned at described storage tank bottom (6) and described jet pipe (10)
Between catalyst gauze thrust chamber (9).
Embodiment 2: a kind of model rocket engine, is characterized in that: described catalyst granules (2)
For potassium permanganate, described working media is hydrogen peroxide.After carrying out quadric catalysis in described catalyst gauze thrust chamber (9), quilt
Be completely decomposed into steam, oxygen produces power from described jet pipe (10) ejection at a high speed.
Claims (3)
1. a model rocket engine, it includes: the shell being made up of storage tank top cover (4), storage tank housing (5) and jet pipe (10)
Body；It is characterized in that: further comprising: be located at the electronic ignition head (1) of described enclosure interior top dead center position, be trapped among described electronics
The catalyst sprinkler of igniter head (1) periphery and catalyst granules (2), encapsulate described catalyst granules from below when normality
(2) block (3), under being located in described enclosure interior, position is for closing the storage tank bottom (6) of described storage tank housing (5), position
In the propellant entrance (8) at described storage tank bottom (6) center, cover the diaphragm (7) of described propellant entrance (8), be encapsulated in institute
Stating the working media that storage tank housing (5) is internal, the catalyst gauze being positioned between described storage tank bottom (6) and described jet pipe (10) pushes away
Power room (9).
A kind of model rocket engine the most according to claim 1, is characterized in that: described catalyst granules (2) is Gao Meng
Acid potassium, described working media is hydrogen peroxide.
A kind of model rocket engine the most according to claim 1, is characterized in that: uses and sprays catalyst granules to advancing
