Rotation Detonation Rocket Engine. Or simply RDRE engine is the next generation rocket system. The big difference between regular rocket engines is that RDRE engine uses screw-shaped burning structure. The simplest way to make an RDRE engine is to make a screw-looking structure in the walls of the combustion chamber. 

The RDRE engine uses less fuel than a regular rocket engine. And that means it's an excellent tool for moon travel. But the RDRE engine can make much more than just transit people between the Moon and earth by using moon shuttles. The RDRE engine can connect with large-size hypersonic aircraft. 

When that hypersonic aircraft starts to make a ballistic jump above the atmosphere. It can turn to use the RDRE engine when it reaches space. That makes it possible to create a real space shuttle that can operate from regular airfields. And that system can make futuristic travel to the moon from regular airports possible. 

But that kind of engine combination can make things like "Mayhem" hypersonic bombers more advanced and more deadly than ever before. The ability to connect rocket engines to hypersonic aircraft is always an interesting thing. That kind of system can make it possible to launch satellites. And the same system can also use in space fighters. 

Researchers are interested in scramjet engines because they use atmospheric oxygen. That gives more space for fuel.  And if the scramjet has a flap at the front of it. And internal oxygen tanks can turn into a rocket. This engine system allows the craft to operate at the orbital trajectory or travel to the moon. 

The RDRE engine could connect with scramjet- or ramjet engines. The idea is that at the front of the engine is the flap that is closed when the aircraft cannot use air from the atmosphere. 

Then the system can turn to use internal oxygen that makes the same aircraft or shuttle able to operate in the atmosphere and space. The system can be more powerful and multi-use than ever before. The screw-looking structure in the ramjet- or scramjet engine will also allow them to fill the chamber more effectively. 

The flap scramjet makes it possible to create hypersonic aircraft that don't need any compressors or regular jet engines for lift-off. At the beginning of the flight, the system uses flap scramjets in rocket mode. When the aircraft's speed is high enough the system turns to use the oxygen from the atmosphere. And if will turn to fly to an orbital trajectory. It turns back to use its engines in rocket mode.

What have we learned from UFOs?

"An illustration of a UFO hovering over a grassy field and road. (Image credit: Aaron Foster/The Image Bank via Getty Images)" (Space.com/10 things we learned about UFOs and aliens (or the lack thereof) in 2022)

The only thing that we seem to learn is that nothing must close out before investigations. The fact is that UFOs:s are real and their origin is unknown. And when we are researching something, we must make real research work to find out what is behind this strange phenomenon. There is the possibility that some government or non-governmental organization on Earth is operating those strange crafts. 

But who is behind those operators who are controlling UFOs? If UFOs are built on Earth, there could be something or somebody who has the right knowledge and skills to make that kind of system. And where that operator staff got equipment for making those unknown crafts? UFOs (Unditenfied Flying Objects) and UAPs (Unidentified Aerial Phenomena) are mysteries. 

When we are thinking. That UFOs are using oscillating membranes for hovering that idea is not wrong. The oscillating membrane allows the craft can hover in the atmosphere. And no one saw the saucer-shaped object rise above the atmosphere. 

There are two possibilities. 

*UFOs are built on Earth. 

*Or they are not built on Earth. 

(An unidentified aerial phenomenon (UAP), as captured by the sensors of a U.S. Navy jet. (Image credit: DoD/US Navy) (Space.com/10 things we learned about UFOs and aliens (or the lack thereof) in 2022)

The big question is who builds those incredible aerial vehicles? If  Russians or Chinese created UFOs. Why are those governments not confess that they have that technology? 

If some private- or non-governmental actor is operating those flying crafts, where they made them? And why are those things kept secret? Where do creators of those crafts get instructions for making that kind of impressive system? 

There is a so-called ancient alien hypothesis that some researchers captured those instructions from ancient Egyptian or Mayan caves or the Himalayas. No evidence supports this theory. There are many interesting things in Mayan caves. That are giving some kind of implied evidence about the ancient aliens. 

In some theories, those UFOs are time machines. That operated by humans from the future. But that is only one theory in multiple theories about UFOs. 

In one of the most impressive alien theories, the generation ship from some alien star arrived in our solar system, spent little time here for repairments, and then continued its route to somewhere. Here I try to tell that no theory is better than others until somebody confesses to keeping UFO in some secretive military base. 

We know that the CIA and U.S. military lied about the UFO research. So there is a question about what else those authorities left out from their public reports. So is some kind of UFO captured in the Roswell incident? 

Or was the thing found in Roswell 1947 some papers or instructions advising how to make UFOs? And who wrote those papers? Did they come from some Egyptian caves? 

But nobody confessed to owning that kind of artifact. And that is the thing that makes UFOs interesting. Why does nobody confess to owning those impressive and superior systems? 

When we think about the users of those crafts, they might not even know how they work. We can compare UFOs with cars. People can drive cars without even knowing, how engines work. Or nothing about the technology that is behind cars. Driver must know how to control the car. 

So we can think that UFOs are some kind of drone. And in that case. Those hypothetical remote operators might not even see them. Remote-controlled drones are also making it impossible that none of those operators can tell about those strange saucer-shaped objects. 

When they start their missions. The small size and incredible maneuverability tell. That at least some of those UFOs operated remotely. The operators might think. That they are using some other top-secret remotely controlled aircraft. 

So the operators cannot tell anything about the mysterious thing called UFOs. The fact is this. The UFOs remain a mystery until one of them is captured. We must look for facts about that mystery.
