Abstract
Provided is a jet system capable of regulating a pressure of a jet substance without using any high-pressure gas supply subsystem. In a storage section for storing therein a jet substance such as fuel or oxidizer, a pressurizing substance such as liquefied gas is stored in addition to the jet substance, to enable the jet substance to be supplied from the storage section according to pressurization from the pressurizing substance. A jet operation is performed while an internal pressure of the storage section lowered along with discharge of the jet substance therefrom is at least partially recovered by at least a part of the pressurizing substance vaporized in the storage section.
Claims10
A jet system operating method comprising:
- providing a storage section and storing therein a jet substance and a pressurizing substance that is a different substance than the jet substance, wherein the jet substance and the pressurizing substance are mixed with each other;
- creating, by a jet flow creation section, a jet flow using the jet substance stored in the storage section;
- and
- jetting, by a jet port, the jet flow created by the jet flow creation section,
- wherein the pressurizing substance is capable of being at least partially vaporized in the storage section to thereby pressurize an inside of the storage section.
A jet system operating method comprising:
- providing a first storage section and storing therein a first jet substance and a first pressurizing substance that is a different substance than the first jet substance, wherein the first jet substance and the first pressurizing substance are mixed with each other;
- providing a second storage section and storing therein a second jet substance and a second pressurizing substance that is a different substance than the second jet substance, wherein the second jet substance and the second pressurizing substance are mixed with each other;
- creating, by a jet flow creation section, a jet flow using the first jet substance stored in the first storage section and the second jet substance stored in the second storage section;
- and
- jetting, by a jet port, the jet flow created by the jet flow creation section, wherein each of the first pressurizing substance and the second pressurizing substance is capable of being at least partially vaporized in a corresponding one of the first storage section and the second storage section to thereby pressurize a corresponding one of an inside of the first storage section and an inside of the second storage section.
A jet system operating method comprising:
- preparing 1st to n-th storage sections, each of the 1st to n-th storage sections defined as a k-th storage section containing a k-th jet substance and a k-th pressurizing substance that is a different substance than the k-th jet substance, where k is an integer selected from 1 to n (where n is an integer of 2 or more) and is assigned in ascending order to each of the 1st to n-th storage sections, wherein the k-th jet substance and the k-th pressurizing substance are mixed with each other;
- creating, by a jet flow creation section, a jet flow using each respective k-th jet substance stored in each of the 1st to n-th storage sections;
- and
- jetting, by a jet port, the jet flow created by the jet flow creation section, and
- wherein each k-th pressurizing substance is capable of being at least partially vaporized in a corresponding one of the 1st to n-th storage sections to thereby pressurize an inside of the corresponding one of the 1st to n-th storage sections.
