The new fundamental technology can change aviation forever.

The NASA X-59 Quiet Supersonic Transportation, Qesst. Is an example of a fast and quiet supersonic aircraft. The idea is that the smooth shapes of the plane make the sonic cone. That is gently sloping relative to the ground. That means. The supersonic cone is used for as long a time as possible. To travel to the ground.

That makes the craft quieter than ever before. Another thing is that fundamental aviation systems like the narrow grooves above the wing or the front spoilers that can lay against the wing can also make the pressure difference between over and below the wing deeper. That thing makes it possible to create an aircraft with shorter wings.

That makes it possible to create new types of supersonic and hypersonic solutions. The X-59 is the system that should make the new type of solution that allows the aircraft to transport things between two points at low noise and supersonic speed. But then we must remember that supersonic speed is medium between subsonic and hypersonic speeds. Before the aircraft reaches hypersonic speed it must accelerate through the supersonic speed area. 

There is also another thing that makes those systems more effective. Things like acoustic tornadoes at the front of the aircraft can push air away from ahead of that plane. Those systems can make the air thinner decrease friction and make it possible to travel faster in low-level flight. 

Focke-Wulff Triebeflüge: the forgotten concept. 

Above: Focke-Wulff Triebflüge in model. 

Rotating wings that can raise aircraft up from the ground. 

The old aircraft can offer the possibility of creating old-new types of VTOL aircraft. Normally the VTOL aircraft turns its nozzle down or uses different lifting motors to rise from the ground. There is the possibility to make the aircraft rise up from the ground using the rotating wing. In late WW2 German researchers created the Focke-Wulf Triebflügel concept. The idea was that the aircraft used one large propeller there were jet engines on their edges. That thing made that propeller rotate. The wing was twisted like in regular propeller aircraft. 

There are flying models of Triebflüger and they show that the system can really work. It could be possible to create a better version of the Triebflüger. The system uses the straight wings that it puts to rotate. Those wings will give the lift force. And then the aircraft can rise up from the ground. When the pilot pushes the stick forward the system turns and locks those wings to the horizontal flight positions. And the engines turn to ahead. That kind of system can also give a high-speed VTOL system the ability to operate. This version just locks those rotating wings to the horizontal flight position when it turns to horizontal flight. 

Tiebflüge was only the model. The aircraft probably flew under Allied control after 1945. But there are flying models of that fundamental, unique aircraft solution. That aircraft remains a concept. But it's an interesting part of the history of aviation.
