RÉSUMÉ

In the last decades there has been an increasing interest in low-cost, low environmental impact liquid propulsion systems, while safety and a short development cycle continue to be essential requirements. This work presents the development of an ethanol and monoethanolamine based rocket fuel, hypergolic with hydrogen peroxide (H2O2), featuring low toxicity and high density-specific-impulse. Initially, a set of tests was carried out to evaluate this parameter in a range of compositions prepared with several catalysts dissolved in monoethanolamine. Among the catalytic materials tested, copper nitrate revealed the shortest ignition delay. Subsequently, a Design of Experiments approach was applied to select the ethanol and catalyst content in the fuel capable of decreasing the ignition delay of the reaction. The results showed that an optimized fuel composition with 61% monoethanolamine, 30% ethanol, and 9% hydrated copper nitrate weight percent, yielded a minimum ignition delay of 15.7 ms.
