PROPELLANTS AND COMBUSTION:
ORBITECís diverse activities in Propellants and Combustion include the synthesis of new, non-toxic propellants, the study of gelled propellant combustion and the development of new diagnostics for combustion and two-phase flows.
The synthesis work involves the development of safe, energetic hypergols, new oxidizers and energetic binders. ORBITEC has developed several non-toxic hypergols designed to replace MMH. The gelled propellant work targets the atomization, vaporization, mixing and ignition of propellant gels. The diagnostic work includes spray analysis, phosphor thermometry and gamma densitometry measurements. ORBITEC has applied gamma to measure void fraction in cryogenic and other two-phase flows relevant to many propulsion applications.
