过氧化氢/丁醇新型燃料着火特性的试验研究

Experimental study on the spontaneous combustion characteristics of hydrogen peroxide and butanol two-component propellant was carried out by droplet collision method. The manganese acetylacetonate was used as a catalyst. The results reveal that increaseing hydrogen peroxide concentration and catalyst content accelerates the reaction and heat release rate of hydrogen peroxide and butanol, shortens the ignition delay time, and enhances the flame brightness and the intensity of combustion. The combustion duration of the mixed fuel droplet gradually decreases with the decrease of the hydrogen peroxide concentration, and increases first and then decreases as the catalyst content increases. In addition, at low catalyst content, the spontaneous ignition range of large volume mixed droplets is significantly larger than that of small volume droplets, but as the catalyst content increases, the influence of the droplets size on the spontaneous ignition range is gradually weakened.
