摘要：
A new concept named two-dimensional fuel pump is proposed, and the advantages are illustrated. To investigate the structural flow ripple of the fuel pump, a simulation model is established in the AMESIM program, and experiments are conducted to verify the efficiency of the pump. The advantages of the axial piston pump in the fuel system are stated through a comparison with the gear pump. The two-dimensional fuel pump is proposed to overcome those structural problems that cannot be avoided in the traditional axial piston pump. The advantages of the two-dimensional fuel pump are illustrated through an explanation of its structure and working principle. The advantages include balanced structural force, high working efficiency, zero direct sliding friction pair, and zero structural flow ripple. To illustrate the advantage of zero structural flow ripple, the simulation analysis and experimental verification are both adopted, verifying that the two-dimensional fuel pump can avoid the structural flow ripple. © 2019, Press of Chinese Journal of Aeronautics.
