Overview
Thermal vacuum (TV) testing is an essential component of spacecraft testing, helping to ensure launch survivability, improve satellite reliability, and establish a path to flight heritage. This is the 1st class on fundamentals of thermal vacuum testing. This course seeks to provide an in-depth understanding of the fundamentals, goals and requirements of thermal vacuum testing for launch vehicles, satellites and satellite components, as well as establishing an educational foundation of the science involved in conducting thermal vacuum testing. By making the underlying science understandable, this course will allow lab managers, engineers, technicians, and mission planners to better understand test requirements and determine the best methods to implement thermal vacuum testing.

The course will first provide a short refresher of the physics and fundamentals of thermo-vacuum testing.  Then, after an overview of typical satellite test requirements, the course will move into a comprehensive review of physics behind vacuum bake-out, thermal vacuum cycling, and thermal vacuum balance testing.

A detailed framework of the vacuum science needed to understand thermal vacuum testing will be taught in a separate class “Application of Thermal Vacuum Testing,” which will review vacuum and analysis hardware with a goal of allowing course-takers to identify the test platform needed to achieve both specific program requirements and overall mission success.

Learning Objectives

  • Understand TV testing requirements, goals, and results
  • Understand the various types of TV tests
  • Understand the physics of heat transfer in a vacuum
  • Understand thermal control methods
  • Understand thermal models and TV test protocols
  • See detailed Outline below
Who Should Attend: These courses are designed for engineers, researchers, students, scientists, and managers interested/ with a need for a detailed understanding of Thermal Vacuum Testing and its myriad applications in spacecraft development. Thermal scientists, satellite engineers, and TVAC technicians/operators will find these courses particularly useful.
