Definitions
- the invention belongs to the field of self-igniting liquid propellants.
- Two-component liquid propellants are widely used rocket liquid propellants, typically consisting of liquid oxidants and liquid fuels, which are typically stored separately and mixed for combustion and providing thrust as they enter the rocket engine combustion chamber.
- Huanzheng propellant can be divided into self-igniting propellant and non-self-igniting propellant according to the ignition mode.
- a combination of smoky nitric acid and dimethyl hydrazine, nitrous oxide and dimethyl hydrazine, dinitrogen tetroxide and methyl hydrazine are all self-igniting propellants.
- liquid oxygen and liquid hydrogen, liquid oxygen and kerosene, red smoke nitric acid and some hydrocarbon fuel compositions are non-self-igniting propellants.
- the self-igniting propellant does not require an additional ignition source, and the engine system using the self-igniting propellant has high reliability and a simple structure. Therefore, self-igniting propellants are widely used in rocket engines for spacecraft such as launch vehicles, satellites and spacecraft.
- the oxidants commonly used in self-igniting propellants are nitric acid and dinitrogen tetroxide.
- Most of the fuels that can spontaneously burn with nitric acid and nitrous oxide are terpenoids, such as dimethyl hydrazine, monomethyl hydrazine, and ⁇ , etc., where the combination of dimethyl hydrazine and nitrous oxide
- terpenoids have the following disadvantages: They are highly toxic, corrosive, and dangerous to fire and explosion. Once leaked, they can cause serious personal injury and environmental pollution.
- the present invention provides a self-igniting liquid propellant composition
- a self-igniting liquid propellant composition comprising the separately deposited components: a tetracycloheptane liquid oxidant selected from the group consisting of nitric acid, dinitrogen tetroxide or hydrogen peroxide.
- the two components separately stored above are mixed in the engine combustion chamber to be self-igniting.
- the nitric acid is fuming nitric acid or red nicotinic acid.
- the fuming nitric acid refers to nitric acid having a nitric acid concentration of 86% to 100%. Due to the strong volatility, gas continuously escapes from the solution, so that the T smoke is emitted, so it is called fuming nitric acid.
- red smoke nitric acid refers to fuming nitric acid in which dinitrogen tetroxide is dissolved, and nitrous oxide continuously escapes therefrom to form red smoke, so it is called red smoke nitric acid.
- red smoke nitric acid Both fuming nitric acid and red nicotinic acid have strong oxidizing properties.
- the present invention provides a self-igniting liquid propellant composition comprising the following separately stored components: Liquid hydrocarbon fuel containing tetracycloheptane
- a liquid oxidant selected from the group consisting of nitric acid, dinitrogen tetroxide, and hydrogen peroxide.
- the two components separately stored above are mixed in the engine combustion chamber to be self-igniting.
- the nitric acid is red smoke nitric acid or fuming nitric acid.
- the hydrocarbon fuel comprising tetracycloheptane further comprises at least one other hydrocarbon fuel selected from the group consisting of aviation kerosene, rocket kerosene or high density hydrocarbon fuel, wherein the other hydrocarbon fuel is relative to the inclusion of four
- the volume percent concentration of the cycloheptane hydrocarbon fuel is less than or equal to 90%, and the volume percent concentration of tetracycloheptane relative to the hydrocarbon fuel containing tetracycloheptane is greater than or equal to 10%;
- the high density hydrocarbon fuel It refers to a hydrocarbon fuel having a density of more than 0.85 g/cm 3 at a normal pressure of 20 ° C, such as JP-10 (hanging tetrahydrodicyclopentadiene).
- the nitric acid is red smoke nitric acid or fuming nitric acid.
- the tetracyclic heptane is a compound having a structure represented by the following formula, and its molecular formula is C 7 H 8 , according to the nomenclature of the International Union of Pure and Applied Chemistry (IUPAC), the chemical name is tetracyclic [3.2. . 0. 0 2 ' 7 . 0 4 ' 6 ]Heptane
- the tetracycloheptane may be derived from any suitable source, for example, commercially available, or photochemically synthesized, using norbornadiene as a starting material, ultraviolet light irradiation, an organic photosensitizer or a solid photocatalyst as a catalyst for the reaction, by precipitation of a diene.
- Intramolecular addition reaction produces tetracycloheptane.
- it can be in accordance with Chinese Patent Application No. 201410052298. 0 (the title is a composite catalyst for preparing tetracycloheptane by isomerization of photocatalytic norbornadiene and a preparation method thereof) and Chinese patent application 201410052297.
- the catalyst and preparation method provided in 6 (the continuous preparation method of high-purity tetracycloheptane) is prepared.
- the oxidizing agent is selected from the group consisting of nitric acid, dinitrogen tetroxide or hydrogen peroxide.
- Figure 1 Photograph of tetracycloheptane added to fuming nitric acid without ignition.
- Figure 2 is a photograph of tetraheptane heptane added to fuming nitric acid to ignite a flame.
- the innovation of the invention is that a hydrocarbon fuel containing tetracycloheptane is found in It can spontaneously ignite when fuming nitric acid, red smoke nitric acid, tetramethylated dinitrogen or hydrogen peroxide are mixed. Such a composition has not been seen in any of the reports of the predecessors.
- the self-igniting fuel composition of the present invention is clearly superior to the existing pyrophoric fuel composition because tetracycloheptane is a hydrocarbon, has low toxicity, is almost non-toxic, and can be transported and stored at normal temperature, and the safety is greatly improved.
