Fuel and Propellant Development

Key Research Topics

• High-energy hydrocarbon fuels for advanced propulsion

• Endothermic fuels for regenerative cooling

• Nano-enhanced fuels and catalytic additives

• Solid fuels and hybrid propellants

• Fuel pyrolysis, ignition, and combustion characteristics

The development of advanced fuels and propellants is essential for improving the performance, efficiency, and operational reliability of next-generation propulsion systems. In high-speed aerospace applications such as hypersonic vehicles and advanced air-breathing engines, fuels are required not only to provide energy but also to perform additional functions such as thermal management and combustion stabilization.

At APEL, we investigate the chemical and thermophysical characteristics of advanced hydrocarbon fuels, nano-enhanced fuels, and solid propellants for aerospace propulsion applications. Our research focuses on understanding fuel decomposition behavior, ignition characteristics, soot formation, and combustion performance under high-temperature and high-pressure conditions. In particular, we explore multifunctional fuel concepts that combine endothermic cooling capability, catalytic reaction enhancement, and improved combustion efficiency.

To achieve these goals, our research integrates experimental combustion studies, advanced optical diagnostics, and multiscale simulation approaches. By combining fuel chemistry analysis, material synthesis, and propulsion system evaluation, we aim to develop innovative fuel and propellant technologies that can enhance the performance of future aerospace propulsion systems while supporting cleaner and more efficient energy conversion.
