No, it's real world engineering. You can't simulate everything when you're doing something totally new. You need to make tests on real hardware to confirm that your model is good.
- sgc 10y agoExact. It is not really any different than going from in-house to beta testing in software to get those real world bugs that always come up -- it is a known step of the design process before even starting.
- hexane360 10y agoEspecially aerodynamics. Modeling fluids alone is very hard and intensive, and that's before you model surface interaction, possible ablation, temperature, shock, and all the other forces present in a dynamic situation. Not doing any x-ray testing would be completely negligent.
