Liquid Rocket Engines for Spacecraft Pressure-Fed Propulsion Systems


This three-day course provides an overview of the fundamental concepts and technologies of modern satellite liquid propellant rocket engines. The course will concentrate on scientific and engineering foundations of pressure-fed, monopropellant, bipropellant, dual mode, and secondary combustion augmented thrusters for satellite orbit-raising and station-keeping operations.

What You Will Learn:

The fundamentals of liquid rocket engine technologies provide an indispensable basis for satellites and their propulsion subsystem design. The basic  fundamentals of thruster design, analysis, and ground testing will make it possible to better understand the role of pressure-fed liquid rocket engines in propulsion subsystem design and satellite operations and will enable the participants to better converse with spacecraft subsystem specialists, mission planners, designers, and operators.

The extensive set of course notes provide a concise reference for understanding, designing, analyzing, ground testing, and operating satellite pressure-fed, monopropellant, bipropellant, dual mode, and secondary combustion augmented thrusters. The course will cover:

  • Thruster valves and injectors
  • Thrust chamber materials and coatings
  • Thrust chamber cooling techniques
  • Combustion instability
  • Ground hot-fire testing
  • Performance analysis
  • Flight operations
  • In-orbit anomaly investigations and resolutions
What you will gain:
  • Technical (scientists and engineers) and managerial personnel will be introduced to the satellite pressure-fed liquid rocket engine technologies.
  • Engineers working on development, design, analysis, and fabrication of thrusters and spacecraft liquid propulsion systems will better understand the place and role of thrusters in the overall spacecraft design – including their interactions and constraints.
  • Managers and program development specialists will appreciate a broad overview of the complexity and technical issues involved in the successful planning, design, development, fabrication, deployment, and operation of space systems.
Who should attend:
  • Engineers and managers in the aerospace/defense industry, FFRDCs and government R&D laboratories and centers who are involved in planning, designing, building, launching, and operating space systems and spacecraft subsystems and components
  • BS degree in science or engineering is required for this course
