This webinar will highlight the integration and acceleration
of many engineering disciplines and tools, from mission and
systems engineering to detailed design and analysis of
rocket propulsion components, featuring technology from
Ansys, ADT, and Flownex.

Description:

  

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   

compact.  

  

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.
