Spontaneous combustion liquid propellant composition

Abstract

The invention discloses a spontaneous combustion liquid propellant composition. The spontaneous combustion liquid propellant composition comprises the following components which are separately stored: quadricyclane and an oxidizing agent which can be nitric acid, nitrogen tetroxide or hydrogen peroxide. The invention also discloses a spontaneous combustion liquid propellant composition comprising the following components which are separately stored: liquid hydrocarbon fuel containing quadricyclane, and oxidizing agent which can be nitric acid, nitrogen tetroxide or hydrogen peroxide. The spontaneous combustion liquid propellant disclosed by the invention uses the low-toxicity harmless quadricyclane fuel, thus being safer and more friendly to the environment than conventional hydrazine fuel and trinitride fuel.

Description

technical field [0001] The invention belongs to the field of spontaneous combustion liquid propellants. Background technique [0002] Two-component liquid propellant is a widely used rocket liquid propellant, usually composed of liquid oxidizer and liquid fuel, which are generally stored separately, and when they enter the combustion chamber of the rocket engine, they are mixed and burned to provide thrust. Two-component propellants can be divided into pyrophoric propellants and non-pyrophoric propellants according to the ignition method. When the oxidant and fuel enter the combustion chamber of the rocket engine, the two-component propellant that can ignite rapidly and automatically is called a self-igniting propellant. For example, the combination of red smoke nitric acid and unsymmetrical dimethylhydrazine, dinitrogen tetroxide and unsymmetrical dimethylhydrazine, dinitrogen tetroxide and methylhydrazine are all pyrophoric propellants. When the oxidant and fuel enter th...

Problems solved by technology

However, hydrazine compounds have the following disadvantages: highly toxic, highly corrosive, high risk of fire and explosion, once leaked, it will cause serious personal injury and environmental pollution

Compared with hydrazine compounds, the toxicity of these compounds has been reduced, and the energy has been improved, but there are still high risk problems, for example, the journal paper GreenBipropellants: Hydrogen-Rich Ionic Liquids that Are Hypergolic with HydrogenPeroxide, Angew. Chem.Int.Ed.2011, 50, 5886–5888 discloses that the pyrophoric fuel burns immediately when it encounters air, and must be sealed and preserved in an inert gas, which brings many difficulties to the production, transportation and storage of the fuel
