Dr. Hal Doiron is the retired VP, Engineering Analysis and Test Division, of InDyne, Inc. He holds a BS Physics degree from The University of Louisiana-Lafayette (1963), and MS and PhD degrees in Mechanical Engineering from The University of Houston (1967, 1970).
As a young Physicist, he joined NASA-Houston in 1963 and developed the Apollo Lunar Module landing dynamics simulation software that was used to guide landing gear design for toppling stability and energy absorption performance; landing techniques development; and to support Apollo landing site selection activities.
He performed docking dynamics studies for the Skylab Program and led the Space Shuttle team from 1972-1979 that successfully eliminated coupled structural/propulsion launch system vibration instability (pogo instability).
After his 16-year NASA career, Dr. Doiron spent 9 years at Reed Tool Co. (1979-1988) developing advanced energy exploration drilling technology as Manager of Technical Services, Manager of Systems Engineering, and Director of the Diamond Products Division. As a Senior Manager at McDonnell Douglas Space Systems (1988-1997), his team computed the on-orbit vibration response of the International Space Station for dynamic events such as spacecraft docking, berthing, re-boost, and rocket plume impingement to define design limit loads and structural strength requirements. He also led a group that performed dynamic modeling, troubleshooting, root cause analysis, and flight anomaly resolution for the Space Shuttle and pogo prevention for the Delta-IV rocket.
In retirement, he is a consultant to NASA and commercial rocket developers for prevention of launch vehicle pogo instability. Because of his Apollo-era landing dynamics experience, he was also selected to be a member of NASA’s Standing Review Board for the Mars rover “Curiosity” entry, descent and landing for the six years of development prior to its successful landing in August 2012.
Dr. Doiron’s experience with complex systems dynamic simulation models used for safety-critical applications, led him to organize The Right Climate Stuff (TRCS) Research Team of NASA Apollo Program veterans, in an independent, objective review of the global warming issue. This team developed and validated the simple TRCS Climate Model, based on Conservation of Energy principles, and published several reports on their website: www.therightclimatestuff.com. They have made presentations at several climate conferences documenting their research conclusions and emphasizing that the present anthropogenic global warming (AGW) alarm results from un-validated climate models that have demonstrated absolutely no skill in predicting the effects of CO2 on climate. The TRCS research team has been an advisor to the Trump Transition Team at the EPA, and recommended EPA public policy decisions should be guided only by physical data analyses and models validated by their accurate explanation of available physical data.
Doiron has spoken at several of Heartland’s International Conferences on Climate Change. View the videos here.
