Problems solved by technology

The materials used for the coating and modification of the above-mentioned nano-aluminum powder are low-energy or inert materials, which affect the energy performance of the fuel, and the coating process is complicated, and will also introduce new impurities into the fuel system. Nano-aluminum powder is surface-coated Finally, due to the change of the surface properties of the powder, the special properties of the nano-powder are reduced. At the same time, the metal powder of the above-mentioned suspended fuel will settle to a certain extent after being stored for a certain period of time, which will also affect the performance of the fuel.
Chinese patent 201810594416.9 reports a nano-energy storage fuel and its preparation method, but its combustion product contains a low-melting and high-boiling sticky oxide, which not only reduces the combustion efficiency of the fuel, but also contains a large amount of residue in the combustion product, which affects Its actual performance in weapons

Abstract

The invention discloses a fluorinated nano-aluminum powder containing energy storage fuel. The fluorinated nano-aluminum powder containing energy storage fuel comprises the following components by mass percent: 3%-40% of fluorinated nano-aluminum powder, 0%-95% of liquid hydrocarbon fuel, 0%-95% of carborane, and 0.2%-5% of performance regulator, wherein a fluorinated nano-aluminum powder is in acore-shell structure taking Al as the center and AlF3 as a coating layer. The core-shell structure nano-aluminum powder is applied to a metal powder containing high-density suspensoid fuel instead ofthe common nano-aluminum powder, the nanometer energy storage fuel is high in density, can ignite rapidly and burn efficiently, has an excellent anti-settlement property, and can be stored stably fora long period of time, and a combustion product has no residue or less residue.

Description

technical field [0001] The invention relates to the technical field of energy storage fuels, in particular to an energy storage fuel containing fluorinated nano-aluminum powder. Background technique [0002] Fuel technology is the core technology, basic technology, and even restrictive technology for the development of aerospace weapons. Liquid hydrocarbon fuel plays an important role in the field of aerospace propulsion, and fuel performance (especially energy and density) is one of the keys to determine flight performance (including range, speed and payload, etc.). The development of high-performance aircraft has put forward higher requirements for the propulsion capability of fuel. High-density fuel has greater mass density and volumetric calorific value, which can provide more energy without increasing the size of the fuel tank, and is a low-cost Vital fuel for rapid flight performance improvements. It is reported that the use of high-density fuel can increase the rang...
