Boom are flying with turbofan engines, not the turbojet engines that were common in the 60s.
As for aerodynamics, the F-22 is relatively efficient at high subsonic speed and also doesn't require external tanks like earlier jets do.
- WalterBright 9y agoWikipedia says that the F-22 is able to supercruise without afterburner, using turbofan engines. This may be the key.
- techdragon 9y agoSupersonic capable turbofans that are able to get the "force multiplier" of using bypass airflow for thrust at supersonic speeds are honestly the key enabling technology here.
- ddalex 9y agoSo basically a supersonic turbofan is a SCRAMJET behind the first fan?
- techdragon 9y agoNot being an expert on supersonic turbofans, I went to the obvious first information source and it was surprisingly illustrative. https://en.m.wikipedia.org/wiki/Turbofan https://en.m.wikipedia.org/wiki/Turbofan From a little further reading it seems it seems that supersonic turbofans are actually just the apex of the continued sophisticated work being done on jet engines which has allowed them to push the intake fans of low bypass turbofans up to supersonic airflow speeds.
