Based on the fluid network algorithm and the idea of time differentiation, a computational model is established for calculating the delay time of aircraft ground pressure fueling. The model solves the problem of complex piping complexity and difficulty in calculating the fueling delay time of the aircraft ground pressure fueling system. According to the specific requirements of the ground pressure refueling system of a certain type of aircraft, the full oil delay time of each group of fuel tanks is calculated under a certain ground refueling pressure. The calculation results are used to validate the ground pressure refueling system of a certain type of aircraft, and the result is good. The calculation model is instructive for the design and performance analysis of aircraft ground pressure refueling system.
