Application and design of dry powder ifre extinguishing system on helicopter lfight deck

Oil fire is a common threat to the helicopter flight deck. This paper analyses the applicability of dry powder fire extinguishing system against the oil fire on the helicopter flight deck according to the fire extinguishing mechanism of the dry power. The results show that the combination of the dry powder fire extinguishing system and the aqueous iflm-forming foam system can achieve a better effect for the extinguishing of the oil ifre on the helicopter lfight deck. The key points of the design and usage of the dry power extinguishing system on the helicopter lfight deck is proposed based on the national and international applications of this system and the relevant rules and regulations.
