Uninformed speculation: I wonder if you could mitigate via a precisely out-of-phase second boom which destructively interfered with the first one? Kind of like noise cancelling headphones. Schlieren photography shows us that there are actually multiple waves being produced over the body based on where the geometry experiences sharp changes, so maybe if those were designed juuust right?
- bernulli 6y agoUnfortunately, it turns out that (for ideal gases, such as our atmosphere) a 'negative shock', i.e. a rarefaction shock, is impossible. It would violate the 2nd law of thermodynamics! And if you have multiple, subsequent shocks (one at the aircraft tip, another at the engine inlet, another at the wing, etc), the later ones will eventually catch up to the first one, resulting in the N wave we would want to avoid.
