As we look at new off-world destinations and applications, 
our launch-vehicle designs constantly need to evolve. Each 
component will need to be optimized for their purpose and 
the mission. Modern cryogenic turbopumps consist of many 
complex components, and it is necessary to model and iterate 
these component's design early on in the development of new 
cycles. 1D system simulation and 3D component simulation, 
alongside rapid, optimized, component design enables 
engineers to develop new turbopump engines with a high 
degree of accuracy and confidence.

In this joint webinar presented by ADT and PADT, we will 
present a workflow for design of cryogenic turbopumps. 
Flownex is chosen for thermal-fluid simulation of the entire 
propulsion system. ADT's unique 3D inverse design method, 
TURBOdesign Suite, will rapidly generate operational maps 
and optimum 3D geometry of the turbopump. ANSYS CFX is used 
for evaluating designs and obtaining the full map of the 
turbopump. ANSYS Workbench with TURBOdesign Suite embedded 
provides an integrated approach to make the turbopump more 

For this analysis, we will use the well-known RS25 Space 
Shuttle Main Engine. We start with a model of the entire 
engine in Flownex and then focus on the main Oxidizer pump. 
This is a double suction pump with inducer - initially 
represented as a basic centrifugal pump in Flownex. Then, 
TURBOdesign Suite is used to create an initial pump stage 
that meets the main requirements in terms of head, flow and 
efficiency as determined in Flownex. The performance of this 
initial stage is analysed by ANSYS CFX at design and off-
design conditions, using single phase and 2 phase analysis. 
Then, the pump stage is redesigned with the goal of making 
the pump more compact while meeting the required duty 
points. The generated maps are fed back into Flownex to 
allow for high fidelity full-system transient simulation.
