Short Courses
Fundamentals of Cryogenics and Cryogenic Analysis
Monday, August 4, 10:00am – 3:00pm
Instructor: Wesley Johnson, Thomas Tomsik and Jeffrey Moder, NASA Glenn Research Center
Thomas Tomsik has over 30 years of experience in scientific research, test operations, and process design, largely in-part focused on the cryogenic engineering of hydrogen, oxygen and nitrogen systems supporting both ground test and space applications. He has been employed as an Aerospace Engineer at the NASA Glenn Research Center for the past 25 years. Mr. Tomsik received his BS/MS degrees in Chemical Engineering from the Cleveland State University and is a registered P.E. in the State of Ohio.
Wesley Johnson has 10 years of experience in cryogenic research, design, and test operations at both Kennedy Space Center and Glenn Research Center.
Jeffrey Moder has 7 years experience in modeling cryogenic systems and over 20 years experience in modeling multi-phase systems at the NASA Glenn Research Center.
Analysis of the extreme conditions that are encountered in cryogenic systems requires the most effort out of analysts and engineers. Due to the costs and complexity associated with the extremely cold temperatures involved, testing is sometimes minimized and extra analysis is often relied upon. This short course is designed as an introduction to cryogenic engineering and analysis, and it is intended to introduce the basic concepts related to cryogenic analysis and testing as well as help the analyst understand the impacts of various requests on a test facility. Discussion will revolve around operational functions often found in cryogenic systems, hardware for both tests and facilities, and what design or modelling tools are available for performing the analysis. Emphasis will be placed on what scenarios to use what hardware or the analysis tools to get the desired results. The class will provide a review of first principles, engineering practices, and those relations directly applicable to this subject including such topics as cryogenic fluids, thermodynamics and heat transfer, material properties at low temperature, insulation, cryogenic equipment, instrumentation, refrigeration, testing of cryogenic systems, cryogenics safety and typical thermal and fluid analysis used by the engineer. The class will provide references for further learning on various topics in cryogenics for those who want to dive deeper into the subject or have encountered specific problems.

After earning a B.S in physics in 1966 and an M.S. in Engineering Science in 1972, Mr. Nieberding has acquired over forty eight years of management and technical experience in the aerospace industry. In his early career, he was a launch team member on over sixty five NASA Atlas/Centaur and Titan/Centaur launches at Kennedy Space Center. He is a widely recognized expert in launch vehicles and advanced transportation architecture planning for space missions. Later, he led and participated in many independent program review teams for NASA Headquarters. Before retiring from NASA Glenn Research Center in 2000, under his direction the Advanced Space Analysis Office led all exploration advanced concept studies for Glenn, including transportation, propulsion, power, and communications systems for many advanced NASA mission applications. Since retirement, he has held numerous consulting positions for NASA and other government agencies. In addition, Mr. Nieberding is co-founder and President of Aerospace Engineering Associates, and co-author and presenter of a highly acclaimed class titled “Mission Success First: Lessons Learned”. He is the father of four children and a husband of forty eight years.
Mr. Ross has been a technical and management contributor in the aerospace industry for over fifty years after having received a BS in electrical engineering from Manhattan College, Riverdale, New York City. His thirty-two year career at the NASA Lewis Research Center, now NASA Glenn, culminated in his assignment as Center Director from 1990-1994. Prior to that assignment he held the positions of Deputy Center Director, Director of Space, and Director of Launch Vehicles. Earlier in his career, he held various positions associated with engineering and program management of the Atlas/Centaur and Titan/Centaur Programs. He was chairman of the Delta 178 Failure Review Board in 1986. Mr. Ross retired from NASA in 1995, and since that time has served as a senior consultant to NASA and other Government agencies, as well as to the commercial aerospace Industry. Mr. Ross is co-founder and CEO of Aerospace Engineering Associates. He is the father of four children and a husband of fifty years.
What went wrong? How did it happen? Could it happen again? How can we avoid repeating the mistakes of the past? No one knows like the people who were there, and have the scars to prove it from personal involvement in space mission failures. The majority of aerospace mishaps can be traced to easily recognized, preventable root causes resulting from a lack of quality somewhere in the system. Most missions are lost to human error, not rocket science. Examining and understanding these causes for more than forty actual aerospace mission failures is critical to helping today’s designers of any highly complex systems, aerospace or otherwise, identify system specific lessons that must be learned. These lessons are not unique to programs or time. They apply across multiple aerospace and non-aerospace endeavors. The same mistakes are being made today that were made fifty years ago. Implementing specific strategies and project “Rules of Practice” early in a program is the best means of prevention. Recognizing why the lessons of the past were not learned is also a critically important step in solving the problem. The “Mission Success First: Lessons Learned” class is “words from the wise” aimed at further strengthening system quality standards by understanding why they broke down in the past, and what to do about it.
This class is among NASA’s most highly acclaimed classes. The importance of the topic has been recognized by NASA and the United States Aerospace community through invitations to present this class more than seventy times in the United States, Europe, and Asia over the past seven years.
