Hypergolic propellants ignite spontaneously upon contact between fuel and oxidizer, without requiring external ignition. We focus on two primary systems:
Hydrogen Peroxide (HTP) Monopropellants
High-concentration hydrogen peroxide (85-98%) decomposes over a catalyst bed into steam and oxygen, producing approximately 2,100 J/g of energy. Advantages include inherent stability, no external ignition requirement, and benign handling compared to strong oxidizers.
White Fuming Nitric Acid (WFNA) Bipropellants
WFNA (HNO₃ with <5% water) reacts hypergolically with fuel compounds to generate high chamber pressures and temperatures. Typical reactions produce specific impulse in the range of 240-260 seconds (in vacuum).
Inhibited WFNA (IWFNA)
We produce IWFNA using iodine pentoxide (I₂O₅) as a corrosion inhibitor. This passivates metal surfaces and reduces corrosion rates significantly, allowing use of standard materials in engine components.
Current Research
Boron-enhanced propellant formulations to increase volumetric energy density. Current work focuses on understanding technical limitations and exploring mitigation strategies through controlled ground testing.
