Aviation fuel pumps of the future are required to be highly efficient and lightweight. As such, this work presents the designs of various mechanisms and structures of advanced two-dimensional piston pumps for aero-engines, and their universal kinematic design methods are detailed herein. The efficiency of various piston pump prototypes was experimentally tested at various speeds in an open circuit. The experimental results indicate that two-dimensional piston pumps have a volumetric efficiency >91% and a higher power-mass ratio than conventional fuel pumps under all the conditions studied. Furthermore, the structural and material problems encountered during testing can provide a blueprint for further improvement of the design and processing of two-dimensional piston fuel pumps.
