Abstract

The invention belongs to the technical field of energy storage fuel and particularly relates to high-energy nano energy storage fuel capable of meeting the use of a missile weapon and a preparation method thereof. The energy storage fuel comprises the following components in percentage by weight: 3-30 percent of nano Al powder, 5-90 percent of liquid hydrocarbon fuel and 7-90 percent of carborane,wherein the nano Al powder is spherical and has an average particle size of less than 150 nm and an active Al content of higher than 90 percent; the liquid hydrocarbon fuel is a petroleum rectification product or synthetic hydrocarbon or two types of compositions. The nano energy storage fuel provided by the invention is high in energy, excellent ignition and combustion performances, simple in preparation method and excellent in sedimentation resistance.

Description

technical field [0001] The invention belongs to the technical field of energy storage fuels, and in particular relates to a nano energy storage fuel capable of satisfying high energy density for missile weapons and a preparation method thereof. Background technique [0002] Fuel technology is the core technology, basic technology, and even restrictive technology for the development of aerospace weapons. High energy and high density are the eternal themes of fuel development, and their performance directly determines the performance level of military power systems for missile weapons. The development trend of liquid fuels shows that high performance, high reliability, non-toxic and pollution-free, low cost, and convenient use and maintenance are the main requirements and directions for liquid propellants in future liquid power systems, and the current liquid fuel varieties cannot meet this requirement. Require. Therefore, the development of a class of high-energy-density fu...
