Abstract: To the simulation of fire fighting pump system of airport fire truck in driving training simulator of airport fire engine, the method of construction of simulation model of fire fighting system was promoted. Simulation model of centrifugal pump of airport fire truck was constructed, which was designed for simplification to satisfy the real-time performance of running of system. Considering fire fighting operation of fire truck, simulation model of operation of fire fighting pump system was constructed, which could not only simulate common fire fighting operation of fire truck, but also simulate running status of low pressure of fire fighting pump. Experiments show, simulation mode of fire fighting pump system can not only satisfy the requirement of real-time running of driving training simulator of airport fire truck, but also has comparably high fidelity.

Key words: driving training simulator of airport fire engine, fire fighting pump system, model of centrifugal pump, real-time performance, fidelity
