AI Technical Summary
In powder fuel scramjet engines, the fluidization and transport of powder fuel is difficult, the supply stability is poor, the ignition delay time is long, the combustion efficiency is low, and the engine faces severe thermal protection pressure and energy loss under hypersonic conditions.
The supersonic combustion engine employs a powder fuel scramjet engine based on metal phase change. By setting up a fuel storage and supply system outside the supersonic combustion chamber, and utilizing the phase change of thermal pressurization materials and low-melting-point metal powders, the fluidized transport and stable supply of powder fuel are achieved, reducing ignition difficulty and improving combustion efficiency.
It enables fluidized transport of powdered fuel, reduces system complexity, improves energy utilization and engine specific impulse performance, and reduces thermal protection requirements and energy loss.
