“ There is still detail design work that will need to be completed. However, both the C4 and C11 configurations come close to an acceptable conceptual design. A small test program would be needed to address some of the outstanding questions. Additional modeling and optimization are also needed at the detail design level. The inclusion of portals, motor attachments, tanks and other peripherals would need to be included in a final analysis. More work needs to be done to define thermal load and cure shrinkage for both the composite cylinder and for the bonded joint. This composite structure is much thicker than most of the structure currently being produced. Thermal strains may play a significant role in the design of the structure. The time required for fabrication and the extended time that the material will be at elevated temperature during cure and bonding needs to be examined. These topics were mostly avoided during the first part of the design cycle. This report describes a conceptual design and a preliminary feasibility study. The design is feasible, but will require additional work in the areas of manufacturing, cure kinetics, material allowable, assembly, and dimensional tolerance.”
In summary - even if Oceangate developed a robust design, they’d still need to manufacture the submarine. It appears they never built enough test articles to develop a baseline for robustness, because they never did destructive testing at depth with actual hardware they never knew their margins and were never able to validate their models to reality.
I have done research and analysis long enough to understand that we all need to remain humble and refrain from assuming a conclusion without substantial evidence.
When I read the sentence “All of which have had deep funding cuts.” I speculate that this response is a simple signal amplification without any added evidence and without critique. I think it’s an attempt at self and collective affirmation.
Who is to say that funding cuts in academia won’t have short and long-term benefits for society and also result in a net increase in happiness and productivity? We simply don’t know yet. Supply and demand of valuable thought and research may redistribute within the economy!
I think there are very political people out there, the world may benefit from forums which cater to people who are political and separately to those who aren’t very political!
