Summary
This is a fast paced two-day course for system
engineers and managers with an interest in improving
their understanding of spacecraft thermal design. All
phases of thermal design analysis are covered in
enough depth to give a deeper understanding of the
design process and of the materials used in thermal
design. Program managers and systems engineers will
also benefit from the bigger picture information and
tradeoff issues.
The goal is to have the student come away from this
course with an understanding of how analysis, design,
thermal devices, thermal testing and the interactions of
thermal design with the overall system design fit into
the overall picture of satellite design. Case studies and
lessons learned illustrate the importance of thermal
design and the current state of the art.
Instructor
Douglas Mehoke is the Assistant Group Supervisor
and Technology Manager for the Mechanical System
Group in the Space Department at The Johns Hopkins
University Applied Physics Laboratory. He has worked
in the field of spacecraft and instrument thermal design
for 30 years, and has a wide background in the fields
of heat transfer and fluid mechanics. He has been the
lead thermal engineer on a variety spacecraft and
scientific instruments, including MSX, CONTOUR, and
New Horizons. He is presently the Technical Lead for
the development of the Solar Probe Plus Thermal
Protection System.
