Flammability Concerns for Ethylene-Glycol and Water (EGW) Coolant

Assumptions Without further details on the system, the ethylene-glycol water mixture is assumed to be mixed and used similarly to how it is used in automobiles: 50:50 mix, likely not greater than 70:30 due to potential limitations in corrosion inhibitors Operating temperature range:  ~195–220 °F (90–104 °C)   The antifreeze mixture will likely not ignite on its own until the water portion is driven off. …

Rotating Detonation Engine Propulsion Integration Efforts at the U.S. Air Force Research Laboratory

Rotating detonation engines (RDEs) have garnered substantial attention as an emerging technology with applications to aerospace propulsion and energy generation due to their high-power density. Significant research and development have improved the operability and performance of RDEs, but relatively few studies have investigated the problems associated with integrating the combustor into an airframe. The U.S….
