NASA launched the BOLT-II mission for researching hypersonic flight




The fact is that hypersonic systems are not always big. And they might seem very much about the normal rockets. Hypersonic aerial vehicles can also use conventional rocket engines for reaching hypersonic speed. The BOLT-II is hoped to collect information about the world. That is beyond the supersonic world.  Hypersonic aircraft need new ideas for making operations secure. 

There is a small metal profile in the rocket. And that profile tests what shape is right for a larger hypersonic vehicle. In image 2 you can see how small the BOLT-II is. And there is also an image of that profile that is used as an aerodynamic test unit in that mission.

Hypersonic flight causes extreme stress on the aerodynamic control levels. And that's why the problem is how to turn the hypersonic vehicle during its flight in the atmosphere. The solution is how to change the course of the hypersonic vehicle can be the air channel that travels through the aircraft. There are branches in that tube. That begins at the nose of the hypersonic vehicle. 

The ventilation will aim the airflow to the right branch. And that turns the vehicle. The BOLT-II that is launched from Wallops Island. Is a demonstration that hypersonic vehicles are not necessarily large. Even fighter aircraft can carry small-size hypersonic vehicles. Those vehicles can carry small satellites to suborbital or ballistic trajectories. 

Or they can use as missiles. Those small-size hypersonic missiles are effective, especially against ships. But as you know those systems are multi-use. And they can use in many different missions in peace and war. And hypersonic technology is a new and interesting area in aviation.

Use virtual "perpetual motion machines" and seawater as energy sources.

   Use virtual "perpetual motion machines"  and seawater as energy sources.  The Archimedean screw can offer almost endless energy sources.  "Robert Fludd's 1618 "water screw" perpetual motion machine from a 1660 wood engraving. It is widely credited as the first attempt to describe such a device." (Wikipedia/Perpetual motion) The term "virtual perpetual motion machine" means a machine. That pulls water to the upper tank using a capillary tube. Then that water will fall through the generator or turbine wheel. The machine uses differences in pressure levels. But it looks like a "perpetual motion machine", that is impossible because of laws of thermodynamics.  The machine uses differences in pressure levels. But it looks like a " real perpetual motion machine", which is impossible because of the laws of thermodynamics.  The real perpetual motion machines don't use outside energy. And that's why they are not possible....

Will humans survive the sun's red giant stage?

"As the Sun matures into a Red Giant, the oceans will boil and Earth will become uninhabitable." (The Conversation, The sun won’t die for 5 billion years, so why do humans have only 1 billion years left on Earth?) Sooner or later, all stars use their hydrogen. And then they turn into red giants. Sun is a yellow G spectral class star that turns into a white dwarf. But before that, the sun will turn larger.  The sun turns red and that means. It starts to send more infrared radiation. This thing will turn Earth into a hellish temperature that vaporizes water from Earth.  It's possible. That Earth will also vaporize with Venus and Mercury. Some scientists say that we have only 1 billion years to move farther in the solar system. The habitable zone will go to the distance of Jupiter and Saturn, and maybe humans find a safe place in those distant moons.  It's possible that before Sun will grow too large humans make large groups of mirror satellites or large shields that sho...

Metamaterials can change their properties in an electric- or electro-optical field.

"Researchers have created a novel metamaterial that can dynamically tune its shape and properties in real-time, offering unprecedented adaptability for applications in robotics and smart materials. This development bridges the gap between current materials and the adaptability seen in nature, paving the way for the future of adaptive technologies. Credit: UNIST" (ScitechDaily, Metamaterial Magic: Scientists Develop New Material That Can Dynamically Tune Its Shape and Mechanical Properties in Real-Time) Metamaterials can change their properties in an electric- or electro-optical field.  An electro-optical activator can also be an IR state, which means. The metamorphosis in the material can thermally activate.  AI is the ultimate tool for metamaterial research. Metamaterials are nanotechnical- or quantum technical tools that can change their properties, like reflection or state from solid to liquid when the electric or optical effect hits that material. The metamaterial can cru...
