- This course is Part 2 of 2, with the first course "Fundamentals of Thermal Vacuum Testing Science". It is recommended, but not required, for students to take both courses, dependent on individual experience and learning needs.
OVERVIEW
This class first provides a very short refresher of the fundamental physics of thermo-vacuum testing, which was covered in detail in the 1st class “Fundamentals of Thermal Vacuum Testing Science.” Then the class reviews vacuum and analysis hardware with the goal of allowing course-takers to identify the test platform needed to achieve both specific program requirements and overall mission success.
