Evaluation of Effectiveness of Solid Fuels Based on High Enthalpy Dispersants for Rocket Ramjet Engines

Resumo

The possibility of replacing the currently widely used ammonium perchlorate as an oxidizing agent (dispersant) in the composition of solid boron-containing fuels for aircraft with rocket ramjet engine was considered by dispersants with reduced nitrogen and oxygen content with a high enthalpy of formation (more than 2 MJ kg⁻¹) and capable of gasifying solid fuels. The efficiency of fuels with high enthalpy dispersants was evaluated in an optimization setting according to the flight range criterion of the aircraft taking into account the complete combustion of fuel in the afterburner chamber. A number of the most effective dispersants were recommended for further study.
