Abstract

Purpose. Determination of optimal technical characteristics and methods of application of the domestic compression foam generating unit.

Methods. Hydraulic calculations, experimental studies.

Findings. The technical features and tactical capabilities of compressed air foam systems (hereinafter referred to as CAFS) are considered. The range of the compression foam jet supply was determined experimentally, depending on the foam characteristics, the diameter of the nozzle of the fire barrel and the overpressure at the outlet from it. The experimental data obtained in the study were used in the development of technical specifications of CAFS – 2/8-50.

Application field of research. The results obtained can be used in developing methodological recommendations for the use of compressed air foam systems for fire extinguishing purposes.
