SUMMARY

This discussion explores the application of metamaterials, specifically carpet cloaking, to mitigate shockwaves in supersonic flight. Participants reference the potential of acoustic devices constructed from metamaterials to influence shockwave behavior, emphasizing the necessity for the speed of sound in these materials to exceed that of the aircraft. Key mathematical formulations, including the Jacobian matrix and its implications for density and bulk modulus, are also highlighted as foundational concepts in this context.

PREREQUISITES
  • Understanding of metamaterials and their properties
  • Familiarity with acoustic cloaking techniques
  • Basic knowledge of fluid dynamics and shockwave phenomena
  • Proficiency in mathematical concepts such as Jacobian matrices
NEXT STEPS
  • Research the principles of acoustic metamaterials and their applications
  • Study the mechanics of shockwave formation in supersonic flight
  • Explore advanced mathematical modeling techniques for metamaterial design
  • Investigate existing studies on metamaterial cloaking, particularly in aerospace contexts
USEFUL FOR

Aerospace engineers, mechanical engineering students, researchers in acoustics and metamaterials, and professionals focused on reducing environmental impacts of supersonic flight.

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.
