Hypersonic Arms Race Heats Up as U.S. Builds High-Speed Missiles | |
Anonymous Coward User ID: 69538569 Finland 03/08/2016 02:35 PM Report Abusive Post Report Copyright Violation | Hypersonic regime is aerodynamically interesting. Not only you have high-supersonic flow and shockwaves to deal with, but you also get a number of chemical reactions induced by the extreme kinetic energy of the projectile. In other words, the surface of the projectile/missile/plane becomes a supersonic flow reactor. It's horribly complicated to model even on a supercomputer. The computing power is not the issue, but the complex non-linear equations that govern the aerodynamic flow. Non-linearity means that everything affects everything and even small changes in the initial values or boundary conditions (e.g. shape of the projectile) will result in drastically changed flow far away from the perturbation. |
