Different Ignition Modes and Temperature Evolution of Typical Hypergolic Ionic Liquids

Abstract: The hypergolic ignition behaviors of three ionic liquids [BMIm]-[DCA], [EMIm][DCA], and [EMIm][CDB] reacting with white fuming nitric acid (WFNA) were investigated using the drop test approach. Two high-speed cameras with/without a long-distance microscope and a time-resolved infrared camera were used to simultaneously record the hypergolic ignition process and the reaction region temperature evolution. Results showed two distinct hypergolic ignition modes. Specifically, for [BMIm][DCA] and [EMIm][DCA], some "… Show more

“…To improve the flexibility of satellite missions, the concept of dual-mode propulsion using energetic fuels was proposed. , This new propulsion solution utilizes the shared propellant and combines the advantages of both chemical and electrospray modes. , However, one of the major challenges in practical applications is the identification of dual-mode propellants with a high enthalpy of combustion and ionization capacity. In this regard, the energetic ILs (EILs) might be the most potential candidates. In 2010, the hydroxylammonium nitrate (HAN)-based EIL named AF-M315E was successfully synthesized and validated in the flight mission in 2019 . After that, other organizations, including Japan Aerospace Exploration Agency and Swedish Defense Research Agency, also began to design similar propellants .…”
