Rocket Engine Electric Pump Feed System
Problem statement
The Wisconsin Space Program (WiSP) requires a LOX and IPA electric fuel pump to obtain higher feed pressures without increasing tank size. Electric fuel pumping systems for rocket engines do already exist, but rocket engines are unique, and so are their feed systems. Additionally, cryogenic fuel pumps on the market are extremely expensive, and as confirmed in Turbopumps for Liquid Rocket Engines, fuel pumps are specific to their engines [1]. Prior works provide valuable insights into the design process and best practices for designing impellers, seals, bearings, and other components [1]. One interesting find in this article was that hydrostatic bearings, when compared to roller element bearings, increase direct stiffness by a factor of 5 and damping by a factor of 100 [1]. This additional stiffness can raise the first critical speed by 50% [1]. With the use of publications from sources like this and NASA, we will provide WiSP with a more efficient fuel feed system.
