Hypersonic AerodynamicsMaturity: concept

Shock, thermal and high-speed flow simulation and geometry optimisation. The live route is misspelled “ypersonic”.

concept An idea we find credible. Nothing has been built or measured.

What this is

The problem

Above roughly Mach 5, the air stops behaving like the air in a textbook. Chemistry becomes part of the fluid dynamics: molecules dissociate, ionise, and exchange energy on timescales comparable to the flow itself. Shock interactions and heating drive the design.

Where the current approach strains

Coupling chemistry to the flow multiplies the state per cell, and the interesting regions demand fine resolution. Ground testing is limited — few facilities reach the conditions, and none hold them for long. Simulation carries more of the design load than anyone is comfortable with.

What we are exploring

Shock, thermal and high-speed flow simulation, and geometry optimisation under those conditions, as part of the wider fluid-simulation programme.

What would have to be true

Validation against the flight and wind-tunnel data that does exist, on the specific regimes where classical solvers are known to struggle. Anything else is a picture, not a prediction.
