- 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.
(Course recorded live in 2022)
- Give participants an overview of the fundamentals of thermal control testing, science, and design for satellites
- Describe existing in industry methods of thermal control which are used for applications of thermal design
- Discuss ways of designing thermal control based on best industry practice
- See detailed Outline below
AUDIENCE: 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.
- AIAA Member Price: $495 USD
