Can Metamaterials Be Used to Reduce Shockwaves in Supersonic Flight?

AI Thread Summary
Metamaterials, such as those used in carpet cloaking, could potentially reduce shockwaves in supersonic flight by manipulating sound waves. The discussion highlights the need for these materials to have a sound speed greater than that of the aircraft for effective shockwave management. Mechanical engineering students engage in a light-hearted debate about using their expertise to shield against shockwaves. Theoretical frameworks, including the Jacobian matrix, are mentioned as part of the acoustic device design process. Overall, the exploration of metamaterials for shockwave reduction in aviation remains a complex and evolving topic.

Could we use something like carpet cloaking to reduce shockwave in supersonic or mach wave in transonic flight?

Just curious... What is "Carpet cloaking" in this context?

Using mechanical engineering students as a carpet to shield from shock waves :-)
At least that would stop them from designing highly CO2 emitting devices.

More seriously: http://en.wikipedia.org/wiki/Metamaterial_cloaking
I suppose you can construct similar acoustical devices. However, I would guess that speed of sound has to be higher in them than the speed of the aircraft.

Thread 'Question about pressure of a liquid'
I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
