Radio transmission is the weak point of modern military drones.

 Radio transmission is the weak point of modern military drones. 


The new British military jet-propelled "Hydra 400"quadcopter is an interesting design. 


The new jet-propelled drone is an interesting design. The jet-propelled quadcopter can fly fast. And it can raise more cargo from the ground than electric engine drones. There is a possibility that these kinds of quadcopters can used as "quad autogyros". 

In those designs, the quadcopters use their quad rotors for lift-off and landing. During a long-distance flight. The drone can use free-rotation propellers and a jet engine. And that thing makes those drones fast. 

Those drones can used as kamikaze drones. Or they can launch missiles like Javelins if they are connected to them. The kamikaze quadcopters are interesting tools because they can observe the area. And if there are no targets those drones can return to base. 

But if there are some kind of targets the drone can make it's surveillance mission and then attack targets when their flight time ends. The drones can use an image-recognition homing system that allows them to take out targets with very high accuracy. 


Above Hydra-drone. 

The military is interested in independently operating drones is that those drones don't require full-time communication between the drone and HQ. The Ukraine war shows how dangerous full-time radio communication is. If the electronic intelligence finds the transmitter, the enemy can turn every cannon against those command centers. So the kamikaze-recon drone can transmit data to the command center and then dive against the target. And that helps to hide the place of the command system. 

The full-time operating radio transmissions are dangerous for drone swarms. The drone swarm where hundreds of members is a suitable target for large anti-aircraft missiles or AA grenades. Similar ELINT systems that are used for track radio transmitters also aim AA cannons at those drone swarms. High-power radio waves can jam the data communication in that drone swarm. 

Those missiles could equipped with a similar homing system as HARM (High-speed Anti Radiation missiles). The HARM-type missiles are also deadly against any radio transmitters. 

Normally HARM is shot from the aircraft. Portable shoulder-launched Stinger missiles also have a so-called "Anti-radiation variant" called Stinger ARM (Anti-Radiation Missiles) that can detect and destroy enemy radiation sources. That makes radio telephones missile magnets if the enemy can track their positions by using radio detectors. 

But there is the possibility that those missiles can be mounted on rocket launchers or warships. Warships can also use those missiles against enemy surface combat unit's radars. And that means the artillery rockets and grenades can have a warhead that can detect radio transmitters.

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
