The X-59 Qesst (Quiet SuperSonic Technology) means a new shape for supersonic and hypersonic aviation. This type of system is extremely streamlined. And that makes it very thin and gentle pressure waves. Those pressure waves travel as long as possible before they hit to ground. And that means those pressure waves can deliver as much energy as possible before they reach the ground.
That technology is useful in both, super- and hypersonic bodies. The silent supersonic and hypersonic systems can revolutionize things like civil and military aviation, and if those turbines use hydrogen, they will not cause emissions. The same thing that makes those next-generation systems quiet makes them hard to detect.
The new materials decrease the aircraft's weight and radar signatures.
New materials like nano-printed titanium have also revolutionized aviation. That new material is 50% stronger than aerospace titanium. The nano-titanium has better thermal abilities than regular, or homogenous titanium. It's possible that in that structure there are things like fullerene or some very cold particles that pull thermal energy in out from the main structure.
In some models, engineers can put things like electronegative particles like protons (hydrogen ions) in that structure. The idea is that when radio waves hit to outer shell, that electronegative structure pulls those radiowaves inside this material structure. Engineers can cover the outer shell of aircraft with very thin structures like nanonet which is a very lightweight composite metal-graphene combination. It's possible that in that structure are small nano-balls that roll when the aircraft moves through the air.

The new metamaterials are the tools that make incredible things. The difference between those new metamaterials and traditional materials is that metamaterials or nanotechnical materials are created atom by atom. The chimeric materials EM. radiation can jump into the structure that pulls it into itself.
If an aircraft can transport thermal energy out from its body. That will make the revolution for hypersonic technology. The biggest problem in high-speed flight is friction. This aircraft must remove this temperature or its structures will melt.
The simplest way to transport heat out from the aircraft's body that decreases its temperature is to make ram-air travel between layers. That air will decrease the aircraft's temperature. But things like active thermal pumps can also make it possible to reach a speed, that is higher than before.
That kind of material must deliver that stored energy somewhere. So, there can be some kind of thermal pump that transfers energy out of the structure. That thermal pump can be the laser ray or some kind of ion beam that travels in the plane. This thing should make radiation travel in one direction in the aircraft's body.
That makes the aircraft more resistant to thermal effects. If an aircraft can remove the thermal effect from its body, that allows it to increase its speed. And that will be a breakthrough in the hypersonic technology.
