Study on the development of aerial fire extinguishing munition for forest fires and fire extinguishing tests

Forest fires are characterized by hidden ignition points, rapid spread, large burning areas, intense flames, and significant influence from meteorological conditions. Due to the complexity of terrain and surrounding environments, conventional firefighting equipment often struggles to reach the core ignition areas from the ground, greatly increasing the difficulty and cost of forest fire prevention and control. Fire suppression munition, due to their ability to control fires at medium and long distances, are commonly used in the field of forest firefighting. This paper conducts research and experiments on the development of new fire suppression munition after analyzing the advantages and disadvantages of current fire suppression munition, aiming to effectively suppress forest fires. Through experiments, it was found that the fire suppression aerial munition were stable and reliable throughout the entire test process. The dispersal range and concentration of the fire suppressant after explosion met the expected requirements. Good suppression effects were achieved in field tests on large ground fires and crown fires, with flames being extinguished and no reignition occurring within 10 min.
