Hypergolic reactions llc
Hypergolically-fueled rocket engines are usually simple and reliable because they need no ignition system. Although larger hypergolic engines in some launch vehicles use turbopumps, most hypergolic engines are pressure-fed. A gas, usually helium, is fed to the propellant tanks under pressure through a series of check and safety valves. The propellants in turn flow through control valves into the combustion chamber; there, their instant contact ignition prevents a mixture of u… Webfuel and the oxidizer of hypergolic reactants, specifically emphasizing the liquid-phase reaction at the point (or instant) of contact. The advantage of micro-fluidic systems lies in their capability to utilize minute quantities of reagents to carry out reactions and analysis with high resolution in a time and cost-efficient manner.
