Metals like titanium are a lot more versatile than composites. For example, titanium has higher ranges of elasticity and it still handles heat remarkably well. Composites like ceramics (honestly don't know about their usage in aircraft fuselages) can handle high temperatures even better but have low ranges of elasticity. At the performance envelope that MiG-31 is capable of (such high linear speeds and still able to pull some rather tight maneuvers), composites may not be able handle what the MiG-31 is capable of.sepheronx wrote:Berkut wrote:And how stable do you think composites would be at M2.8? Point being; replacing metal to composite panels would be useless on MiG-31 and would not offer any extra performance but rather give worse performance.
I thought composites were generally lighter and stronger than Titanium?
I am just saying it would also help with RCS reduction, at least that was the main selling point for newer jets that replaced most metal on surface with composites. But that doesnt deter me from wanting to see newer made MiG-31's
Awesome. Thanks for the explanation. I didn't know this. +1.
