Characterization and performance analysis of eco-friendly solid rocket propellant from Prunus armeniaca L. agricultural residues

Year: 2025

Type: article

Abstract: The increasing demand for sustainable energy solutions has prompted the aerospace industry to explore alternative fuels that minimize environmental impact. This study investigates the potential of utilizing apricot waste, a by-product of the agricultural sector, as a feedstock for solid rocket propellant (SRP) production. Through innovative conversion processes, including sulfurization and caramelization, apricot waste was transformed into a viable propellant. The resulting SRP exhibited favorable chemical properties, including a high calorific value of 1726 cal/g, indicating its potential for efficient energy release during combustion. Elemental analysis revealed a composition that is rich in oxygen, enhancing its eco-friendliness compared to traditional propellants. The moderate burn rate exponent ( n ≈ 0.602) suggests a balanced performance, making it suitable for applications requiring controlled thrust profiles. This research not only addresses the environmental challenges associated with conventional propellants but also highlights the importance of repurposing agricultural waste, thereby promoting sustainable resource utilization and waste reduction.
