Turbomachinery for Emerging Space Applications: Liquid Rocket Propulsion

In This Section

Overview

The design of liquid rocket engines requires careful considerations to ensure that mission requirements can be met safely. This 24-hour course will cover an introduction to the interdisciplinary design of turbomachinery components within their corresponding systems in the context of liquid rocket engines. Focus will be made on theory and will be illustrated with practical examples throughout the course, including through follow-along portions where attendees will be able to model cycles, perform turbine conceptual design, and more using the AxSTREAM® platform. Relevant topics include rocket cycles, turbine, pump, secondary flow, and rotor dynamics.

 Learning Objectives 

  • Going from mission requirements to turbopump design
  • Liquid rocket engine cycles
  • Understanding how turbopumps fit into a launcher vehicle
  • Modeling fluid properties
  • Designing subsonic and supersonic axial turbines for space application
  • Designing cryogenic pumps for the propellants involved
  • Specificities of rocket pumps compared to industrial ones
  • Understanding system behavior when all turbopump parts are coupled
    • Secondary flows
    • Rotordynamics
  • Benefits of flexible, integrated, multi-disciplinary design software
Who Should Attend: This course is intended for students, engineers, and managers involved or interested in the aero-thermodynamic and structural design of liquid propulsion turbomachinery components as well as how they fit in the rocket through their relevant systems.

Mr. Clement Joly is a Senior Manager at SoftInWay and has been with the company since January 2013. He received his Master’s Degree in Mechanical & Aerospace Engineering from Polytech ’Orleans in France and attended engineering classes at Wichita State University in Kansas (USA). Mr. Joly specializes in traditional and emerging technologies linked to turbomachinery components and systems.
 
Dr. Vlad Goldenberg joined SoftInWay after completing a Ph.D. in Mechanical Engineering at the University of Minnesota. His doctoral research involved the development of a novel aerodynamic synthesis method for a centrifugal compressor stage, and integrated CFD with optimization, AI, and machine learning. His other research involved novel heat pump modeling and optimization, and flow and heat transfer in porous media, with applications in heat transfer enhancement. Vlad’s research interests are in the areas of computation and modeling of thermal and fluid systems to solve complex engineering problems. Vlad has been a practitioner of turbomachinery analysis and design for over a decade. He implemented analysis methods on axial power generation gas turbines and steam turbines, also involving complete thermal engineering on the entire power generating process. He also developed centrifugal compressors for HVAC chillers, incorporating thermal modeling of the cycle into the design of the flow path, culminating in preliminary design through a full CFD analysis of compressor stages. Vlad holds B.S. degrees from UC Berkeley, M.S. from the University of St. Thomas, and Ph.D. from the University of Minnesota.
