The hypersonic missile can use rocket engines.

Connecting normal jet engines to rocket aircraft is not often mentioned as the way to increase the capacity of the aircraft. That thing can turn into hypersonic aircraft or cruise missiles. So the rocket aircraft will equip with jet engines. The rocket-based hypersonic missiles are maybe already in operational use. Those missiles are using rocket engines for accelerating their speed to highly super- or hypersonic. 

The rocket aircraft can work as a hypersonic missile. The most conventional version of hypersonic aircraft has been missing from the great public. The system would have jet engines that it can use for slow-speed flight. When the system requires the maximum speed it just turns to use the rocket engine. The air-launched systems might be regular missiles, which have different flight profiles than usually. The hypersonic missiles don't require a scramjet engine. And the simplest way is to use solid rocket engines. 

When we are thinking of the word hypersonic missile, we must understand that this kind of weapon can use traditional rocket engines. And that means the hypersonic missile and especially the HCS (Hypersonic Cruise System) can be the small-size rocket aircraft or something like Pegasus-rocket that is aimed at the target. 

The Russian Kh-47 Kinzhal ("dagger") ALBM (Air-Launched Ballistic Missile) missile that is seen under the MiG-31K interceptor is this type of weapon. Wikipedia tells that Kinzhal uses a solid rocket engine. Officially Kinzhal is an air-launched ballistic missile, but it can have different flight profiles. 

When that system hits the target, that thing can destroy all kinds of things like ships and hardened bunkers. The HGS (Hypersonic Glide System) is the warhead that looks like a small glider or the spearhead, that can hit the target from different angles than the regular ballistic missile warhead. 

One of the versions of the HGS is the aircraft with regular jet engines. And when the system needs maximum speed it just activates the rocket engines. That rocket engine can be the aerospike engine between the jet engines. The aerospike would have troubles in high-altitudes, but at the altitudes, from 1000 to 10 000 meters that thing can work very fine in that kind of mission. 

The aerospike engine would work in the low altitudes, and the HGS will cruise to the strike distance from the target, and then it will activate the aerospike system. That thing will give the maximum speed to the target. This is only one version of the hypersonic system. 

The system bases the existent technology. And it can be a powerful and dangerous system. For making strikes to the enemy territory. That kind of system is not very hard to make. They are basing normal conventional technology.

Chinese innovations and space lasers are interesting combinations.

Above: "Tiangong is China's operational space station located in low Earth orbit. (Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft.  Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things.  In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion.  If we th

Iron Dome is one of the most effective air defense systems.

The Iron Dome is a missile defense system whose missiles operate with highly sophisticated and effective artificial intelligence. The power of this missile defense base is in selective fire. The system calculates the incoming missile's trajectory. And it shoots only missiles that will hit the inhabited area. The system saves missiles and focuses defense on areas that mean something. The system shares the incoming missiles in, maybe two groups. Another is harmless and another is harmful.  Things like killer drones are also problematic because their trajectories are harder to calculate than ballistic missiles. The thing that makes drones dangerous is that they can make masks for ballistic missiles. And even if those drones are slow, all of them must be shot down.  The thing is that the cooperation between drone swarms and ballistic missiles is the next danger in conflict areas. In the film, you can see how drones make light images of the skies. The killer drones can also carry LED li

The innovative shield that protects OSIRIS-APEX can also protect the new hypersonic aircraft.

"NASA’s OSIRIS-APEX spacecraft successfully completed its closest solar pass, protected by innovative engineering solutions and showing improvements in onboard instruments. Credit: NASA’s Goddard Space Flight Center/CI Lab" (ScitechDaily, Innovative Engineering Shields NASA’s OSIRIS-APEX During Close Encounter With the Sun) The OSIRIS-APEX probe travels close to the sun. The mission plan is to research the sun. And especially find things that can warn about solar storms. Solar storms are things that can danger satellites at the Earth orbiter. And the purpose of OSIRIS-APEX is to find the method of how to predict those solar storms. Another thing is that the OSIRIS-APEX tests the systems and materials that protect this probe against heat and plasma impacts.  The same technology. The researchers created for OSIRIS-APEX can used in the materials and structures. That protects satellites against nuclear explosions. That means this kind of system delivers information on how to prot
