Abstract

Aimed at the design of non pressure-accumulated and handheld fire extinguishing bomb, the rules of the influence of structure on jet performance were studied by the method of equivalent diameter and distance. The factors such as diameter of the burning area of gas-generating agents, length-to-diameter ratio of cartridge, internal taper of sealing cap, and nozzle diameter were analyzed employing single factor tests on the influence rules for the best jet distance and the largest strewn area, then the orthogonal tests were carried out within a safety index, which is, the jet distance is greater than 2.4 m. Results show that under the optimum structure combination where the diameter of burning area is 18mm, length-to-diameter ratio 160 mm/50 mm, internal taper 130º, and nozzle diameter 7 mm, the largest strewn area is 1.30 m2.
