Method for establishing and analyzing water flow distribution line model of independent fuel warm air vehicle

The invention discloses a method for establishing and analyzing a water flow distribution line model of and independent fuel warm air vehicle. The method comprises the following steps: 1) collecting or calculating parameters required by model analysis; 2) establishing each branch pipeline sub-module according to the parameters obtained in the step 1); 3) connecting the established sub-modules according to the connection mode of each module in the CAD model of the pipeline arrangement of the whole vehicle to obtain a model; 4) collecting parameters needing to be subjected to data conversion, and completing data conversion; 5) simulating different working conditions by using the established model; and 6) according to the different working conditions simulated in the step 5), calculating a water flow distribution result in the component and carrying out evaluation analysis. According to the invention, the distribution condition of the water flow of the whole independent fuel oil warm airvehicle can be simulated,
