Modification design of aircraft ground pressure refueling system

In order to meet the future operational requirements, the gravity refueling system of the existing aircraft needs to be modified to meet the pressure refueling requirements, and the traditional analysis method can only carry out segmental research on each part of the fuel system, and must be conducted on the complete fuel system modeling and analysis is very difficult. In view of this, this article starts from the composition principle of aircraft pressure refueling and related pressure refueling technical requirements. Through establishment and simulation analysis of the system model by
Flowmaster
, it is concluded that the original pipeline does not meet the existing pressure refueling requirements. Finally, the refueling pipeline system is optimized based on the flow distribution theory, in order to provide a useful reference for the subsequent pressure refueling test.
