Abstract: The ignition and combustion properties of liquid monopropellant LP1846 droplet havebeen investigated in hot convection ambience. Time series photographs of the droplet from heated tofully burned are given. The characteristic parameters of ignition and combustion of the droplet aremeasured quantitatively. The mechanisms of droplet microexplosion are also discuss. A simplifiedengineering calculation model on ignition of droplet is also set up.
