Abstract Fine and ultra‐fine powders are actively studied in pyrotechnics, explosives propellants. The important questions how to produce a powder with specified characteristics use the produced.
Combustion of dispersed metals in an oxidizing environment is practical interest, which related to the prediction characteristics high-energy compositions (HECs) containing metal powders, as well various propulsion systems and gas generators. The research studies peculiarities ignition combustion Al, B Al-B mixture products formed during thermal decomposition HEC components. In study combustion, development flame processes, a continuous CO2 laser (high-speed radiant heating)...
Metal and metalloid powders are widely used in high-energy compositions (HECs) solid propellants (SPs), increasing their energetic characteristics the combustion chamber. The particle size distribution, protective coatings of particles heat metal influence ignition parameters HECs as well propulsion systems. Boron-based metallic fuels achieve potentials during combustion. effect Al-B, Fe-B Ti-B (Me-B) mixture ultrafine (UFPs) on a model HEC based oxidizer polymer combustible binder was...
Abstract The study of the ignition characteristics high‐energy materials (HEMs) is important in solving a number practical problems related to assessment explosion safety, calculation transition processes power installation for various purposes (rocket and space technologies, weapons, pyrotechnics). This paper presents experimental data on thermal oxidation ultrafine powder (UFP) based Al/B, Ti/B, Ni/B, Fe/B HEM ammonium perchlorate, butadiene rubber, metal fuel. In course processing...
The solid fuel gasification process was investigated to define chemical reactions rate and activation energy for a gas-generator designing regime optimizing. An experimental procedure includes coal char samples of Kuznetskiy Kansko-Achinskiy deposits consequent argon pyrolysis into oxidating carbon dioxide with different temperatures. thermogravimetric analysis data obtained in the temperature range 900–1200 ºC. mass loss time dependencies from were defined calculate reaction frequency...
Acoal conversion process of different coal samples into three types oxidizing medium (argon, air and steam) were studied by means thermogravimetry. Two with metamorphism degree (lignite bituminous coal) used. The experimental procedure was carried out in non-isothermal conditions temperature range from 373 K to 1273 20 K/min heating rate. Purge gas consisted argon oxidizer volumetric ratio 1:24 had 250 ml/min flow rate.The ignition burnout indexes calculated evaluate sample reactivity at...
Boron and its compounds are among the most promising metal fuel components to be used in solid propellants for rocket engine ramjet engine. Papers studying boron oxidation mostly focus on two areas: of single particles powders boron, as well boron-containing composite propellants. This paper presents results an experimental study ignition combustion high-energy material samples based ammonium perchlorate, nitrate, energetic combustible binder. Powders aluminum, amorphous aluminum diboride,...
The high heat of combustion makes boron and metal borides attractive as a fuels additive in solid propellants hybrid fuels. formed liquid B2O3 oxide layer on the particles during prevents complete results higher burning time particles. Aluminum are characterized by melting point when heated an oxidizing environment they oxidized to form Al2O3 oxides. This study investigates chemical activity powders based aluminum, titanium, which can be used high- energy materials fuel additives. paper...
The ignition data on Siberian bituminous coal and lignite by a continuous CO2-laser were presented in current work. Measurements carried out at the heat flux density range of 90–150 W/cm2 air. Dependences delay time obtained along with surface temperatures moment fuel sample ignition. Ignition was found to be 50–520 ms for lignite. For values are larger 1.5–2 times. However, temperature is same both fuels, i.e. 640–680 °C.
