Hydroxylammonium nitrate （HAN）-based propellant has the advantages of high energy， insensitive and non-toxic combustion products. It offers advantages in the continuous start-up and thrust adjustment of propulsion system. The formula composition， decomposition characteristics， ignition and combustion performance of HAN-based liquid propellant， HAN-based gel propellant and HAN-based solid propellant were reviewed. The key points for future research were proposed： preparing high-performance catalyst bed for HAN-based liquid propellants， developing electric ignition as a reliable ignition mode； improving the ignition performance of HAN-based gel propellant， accelerating the engineering applications； exploring the combustion and flameout controllable mechanism of HAN-based solid propellant， and breaking through the bottleneck of large-scale application of the propulsion system.
