The present disclosure relates to a throwing device with a two-stage propulsion system, especially, using the solid fuel.
Throwing devices, for example, rockets, take essential parts in the battle field. Today, throwing devices also take essential parts in our lives. As the solid fuel becomes popular and safer, it also changes types of the propulsion system of the throwing device.
For example, a throwing device with a fire-extinguishing rocket can be used to handle blazes far away from an operator. The throwing device, which may have a rocket launcher, can fire a rocket filled with a fire-extinguishing agent to hit the fire source dozens of floors up. The rocket is capable of going through the window and spreading the fire-extinguishing agent inside a house. Therefore, the operator can put out the fire without getting into the house. As another example, a throwing gun may also have a rocket launcher as the propulsion system to make a rope reach a far place. However, while the propulsion system is launched, lots of smoke and heat may be produced and emitted, and it may harm people who stand nearby. Therefore, an invention for the throwing device to avoid such risk is required.
One aspect of the present disclosure provides a throwing device comprising: a propulsion system and a launcher. The propulsion system comprises: a first section comprising a first chamber containing a first propellant, and an igniter for igniting the first propellant; a second section that is connected to the first section and comprises a second chamber containing a second propellant; and a retardant set between the first propellant and the second propellant for delaying the combustion from the first propellant to the second propellant. The launcher comprising: a tube for containing the propulsion system; and a trigger for triggering the igniter.
By delaying the combustion from the first propellant to the second propellant, the propellant will not be burned at once, and the emitted smoke and heat can be decreased. Thus, people who stand nearby will be safe.
Another aspect of the present disclosure provides a throwing device comprising: a propulsion system and a launcher. The propulsion system comprises: a first section comprising a first chamber containing a first propellant, and an ignition cartridge for igniting the first propellant; a second section that is connected to the first section and comprises a second chamber containing a second propellant; and a retardant set between the first propellant and the second propellant for delaying the combustion from the first propellant to the second propellant. The launcher comprises: a tube for containing the propulsion system; and a trigger for triggering the ignition cartridge. Optionally, a screw hole is in center of a bottom of the first chamber; nozzles are located around the screw hole; and a collar with a hole fixed under the bottom of the first chamber, wherein the ignition cartridge is fixed in the screw hole by the collar. Optionally, the ignition cartridge comprises an explosive primer, and the launcher further comprises a firing pin triggered by the trigger to hit the explosive primer. Optionally, the launcher further comprises ignition coils controlled by the trigger to ignite the explosive primer.
The foregoing has outlined rather broadly the features and technical advantages of the present disclosure in order that the detailed description of the disclosure that follows may be better understood. Additional features and advantages of the disclosure will be described hereinafter, and form the subject of the claims of the disclosure. It should be appreciated by those skilled in the art that the conception and specific embodiment disclosed may be readily utilized as a basis for modifying or designing other structures or processes for carrying out the same purposes of the present disclosure. It should also be realized by those skilled in the art that such equivalent constructions do not depart from the spirit and scope of the disclosure as set forth in the appended claims.
A more complete understanding of the present disclosure may be derived by referring to the detailed description and claims when considered in connection with the Figures, where like reference numbers refer to similar elements throughout the Figures, and:
Embodiments, or examples, of the disclosure illustrated in the drawings are now described using specific language. It shall be understood that no limitation of the scope of the disclosure is hereby intended. Any alteration or modification of the described embodiments, and any further applications of principles described in this document, are to be considered as normally occurring to one of ordinary skill in the art to which the disclosure relates. Reference numerals may be repeated throughout the embodiments, but this does not necessarily mean that feature(s) of one embodiment apply to another embodiment, even if they share the same reference numeral.
It shall be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers or sections, these elements, components, regions, layers or sections are not limited by these terms. Rather, these terms are merely used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present inventive concept.
The terminology used herein is for the purpose of describing particular example embodiments only and is not intended to be limited to the present inventive concept. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It shall be further understood that the terms “comprises” and “comprising,” when used in this specification, point out the presence of stated features, integers, steps, operations, elements, or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or groups thereof.
By referring to
While the propulsion system is launched and a person may be stand near the propulsion system or inside a house, the amount of the emitted smoke and heat is required to be decreased to prevent the person from being harmed, the retardant set 130 may be installed between the first propellant 114 and the second propellant 124 to keep the combustion from the first propellant 114 to the second propellant 124, however, with the decreased smoke or heat. For example, by referring to
Optionally, the thickness d of the space 130′ for containing the retardant set 130 may be about 1 centimeter by way of example but not limitation. Optionally, the second propellant 124 comprises Sorbitol, Potassium Nitrate, and Iron Oxide, and a ratio of Sorbitol to Potassium Nitrate of the second propellant 124 is about 35 to 65 in weight.
By referring to
Although the present disclosure and its advantages have been described in detail, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the disclosure as defined by the appended claims. For example, many of the processes discussed above can be implemented in different methodologies and replaced by other processes, or a combination thereof.
Moreover, the scope of the present application is not intended to be limited to the particular embodiments of the process, machine, manufacture, composition of matter, means, methods and steps described in the specification. As one of ordinary skill in the art will readily appreciate from the disclosure of the present disclosure, processes, machines, manufacture, compositions of matter, means, methods, or steps, presently existing or later to be developed, that perform substantially the same function or achieve substantially the same result as the corresponding embodiments described herein may be utilized according to the present disclosure. Accordingly, the appended claims are intended to include within their scope such processes, machines, manufacture, compositions of matter, means, methods, or steps.
