Abstract

Among the green hypergolic propellants increasingly explored as less hazardous alternatives to conventional in-space propellants like monomethylhydrazine and dinitrogen tetroxide, high-test peroxide (HTP)and novel fuels offer promising reactivity and performance. This study investigates the hypergolicity of green bipropellant combination dimethylthioformamide (DMTF)/HTP. Physical and thermochemicalproperties were determined, and performance metrics estimated by simulation. Drop tests evaluated ignition delay time (IDT), examining the effects of fuel additive concentration, drop height and configuration, and mixture ratio. Adding 6 wt% copper(II) chloride to DMTF significantly reduced IDT(13.71 ± 0.86 ms). Results indicate that DMTF/HTP may be a viable green hypergolic pair.
