| Abstract: |
| In view of the design requirements of a certain type of cockpit heating system, a set of design method combining theoretical calculation with experimental simulation is established. This method establishes a preliminary heating system model through the previous principle design and theoretical calculation. According to the related physical variables in the model, the matching test process is set up. Through experimental verification and data analysis, a perfect heating system scheme has been formed. This scheme optimizes the distribution of cold and hot air flow by the method of ejection plus bypass. The rationality is verified by the ground test and the iterative design. |
