Volute for engine-mounted boost stage fuel pump

摘要

A centrifugal pump housing 28 has walls that define a volute passage 88, 90 and a diffuser passage 92 fluidly connected to the volute passage 88, 90. The volute passage has a first subsection 88 and a second subsection 90, each having cross-sectional areas defined by tables of coordinates. The housing may be used for an aircraft engine boost stage fuel pump.
