Presentation: March 2022

This month's AE presenter: James Aubuchon
Date of presentation: 21-March-2022
Subject: Heat Pipes
Description: In this presentation from his "Space Systems" series, on the subject of heat management, Jim talked a bit about heat pipes - the structures designed to move heat energy generated by or radiated onto a system to another area where it is less likely to interfere with the proper operation of the system.  Most of these seemed to involve the circulation of some sort of cooling fluid (not necessarily water) from Point A where they pick up heat to Point B where they get rid of it.  Unlike a car radiator, however, there is virtually no air cooling in space, and vacuum is an excellent insulator, both of which make the actual heat transfer a bit more complex.

Presentation: February 2022

This month's AE presenter: James Aubuchon
Date of presentation: 7-Feb-2022
Subject: Space Systems: Heat Management (part 2)
Description: This week, Jim gave the second "half" of his Heat Management presentation.  Since he had delivered most of the material in part 1, this became largely a question/answer session.  But Jim did break part of the topic away and will talk solely about heat pipes in March.

Presentation: January 2022

This month's AE presenter: James Aubuchon
Date of presentation: 31-Jan-2022
Subject: Space Systems: Heat Management (part 1)
Description: In this month's presentation, part of the "Space Systems" series, Jim talked about heat management on a space system - how heat has a number of sources, stemming from not only electronics, but also friction from moving parts, as well as radiation from the Sun and other sources.  Since a space system cannot be expected to deal with steadily increasing heat indefinitely, pains must be taken not only to generate as little as possible, but also to route the heat energy away from sensitive areas.

Since Jim was unable to complete this presentation in the allotted time, it was continued the following week.
