AI Technical Summary
Existing aircraft fire suppression systems face challenges with the use of trifluoroiodomethane (CF3I) due to its low stability at high temperatures, leading to breakdown and inefficient distribution, particularly when discharged from ceiling-mounted systems.
The system employs CF3I as a fire suppression agent discharged from lower outlets in the cargo compartment, using computational fluid dynamics to model temperature distribution and ensure sufficient momentum, with outlets positioned in the cheek areas and lower portions of the compartment to maintain stability and effectiveness.
CF3I maintains stability and effectiveness even at high temperatures, ensuring efficient fire suppression with calculated half-lives exceeding 10 hours, avoiding component damage and maximizing cargo space.
