Yan Xia was only talking about the scope of exploration by explorers. But for the Federation, these explorers will definitely not go too far. After all, too far is the lonely starry sky. At least so far, no race in the Federation is truly a solitary race. They all rely heavily on the material and spiritual satisfaction provided by living in groups. So roughly 30 years after the expansion plan was proposed, Yan Xia and Ella started researching an item. ——Sublight speed aircraft The so-called sublight speed is more than 90% of the speed of light, which is greater than 270,000 km/s. The Federation has actually been working on sublight speed aircraft for a long time, but it has not been applied in the military field before. Yan Xia checked it in the civilian field and found that it is widely used. Generally speaking, it is used to transport items. But with super-hedged material transfer devices, the market for such material transfers is compressed to a very small extent.
The super hedging material transfer device has the problem of incomplete information transmission. If it is to transfer something with stored content at this time, it will not work. For example, someone has a memory card that stores some precious information or pictures. If it is transferred using super hedging substances, it may be damaged. These things are difficult or inconvenient to repair. This is the application space of sub-light speed aircraft. At the same time, sub-light speed aircraft are also assembled on some spacecraft. Explorers will first send these sub-light speed aircraft to the surface of the planet to be explored, and then approach after confirming the planet information to avoid accidents. Although these markets are not too large, they can already support the scale of trillions of energy coins. Therefore, there are still some scholars in the federation who specialize in this area, and some companies are carving up these markets. One of the largest companies is called A Shewen. It sounds like a strange name, but it is actually a transliteration of the language of the Kate tribe, which means colorful and also means colorful. Yan Xia asked Ella to study their technology carefully, and then integrated it with the sublight speed aircraft technology of other similar companies on the market. In the end, Ella developed a super-large sublight speed aircraft. The aircraft is named Baiju It weighs about 92kg and looks like a bullet. The internal storage space can carry items no more than 3kg. This size sounds heavier than a human race, but the average sublight speed aircraft only weighs 30~50kg. In comparison, this is already considered very large. The core technology of this sub-light speed aircraft does not actually lie in the aircraft itself, but in its launch device. Therefore, enlarging the body size not only requires higher technology, but also can work hard on cost performance. As long as you don't think about making money, it is relatively easy to increase the weight of the sublight speed aircraft to more than 70kg. Looking at the sublight speed aircraft in front of him, Yan Xia felt extremely delicate. It exudes a glass texture and is extremely reflective. The warhead is actually round, not a cone. There is a fist-sized painting at the position of the warhead, divided into many colors, and the centers of these colors are also numbered.
Yan Xia picked one up casually and weighed it twice. More than 90 kilograms is still a bit heavy to hold in your hand. Yan Xia single-handedly loaded him into a cannon hole installed on the surface of Free Star City. He was now standing on a tall building, which was almost 140,000 meters high. A gravity elimination device was placed on the top of the building. The gravity of Free Star City itself is still relatively large. Even without a gravity device, the gravity exceeds the gravity of Mars. After eliminating all external influences, Yan Xia pressed a button next to her. The sublight speed aircraft did not fly out immediately, but energy state rings began to appear in front of the blast hole, which felt a bit like Mach rings or donuts. These rings of energy state exist almost every 1 meter, extending 1 million meters into outer space. "The acceleration ring is in place." A cold voice sounded. It was a mechanical voice commonly used within the federation, also called mass voice, because it was synthesized from the voices of 100 million people. Acceleration rings are a commonly used method of accelerating small objects nowadays. They briefly accumulate energy in a certain area. This energy will be compressed to the surface of the object the moment the object passes through it, and then quickly give a push backwards. Ella really wants to apply this to large-scale devices. Maybe some starships or even spaceships can easily reach more than 100,000 km/s. Unfortunately, the energy it requires is too high and is impractical. "emission!" As the sound fell, the sublight speed vehicle was launched. I saw layers of accelerating rings gathering behind it to form high-energy jets and spurting backwards. The reaction force quickly accelerated the sublight speed aircraft from 8,000km/s at the moment of launch to more than 200,000km/s. Finally, the speed of the sublight aircraft reached 271279km/s. "I hope they can explore further afield. Their goal is the star field within 5,000 light-years." Judging from the time, its mission will be completed in 5525 years, which is almost the same as the speed of light. The main purpose of these sub-light speed vehicles in the harsh summer is to explore the surrounding starry sky, and only explore. Since these aircraft do not need to accelerate, the entire aircraft is a huge exploration device, and no part is redundant. On the top of the aircraft is a miniature detection and avoidance device to avoid cosmic dust and adjust the course. Although the probability of an aircraft hitting cosmic dust is about the same as that of an ordinary person winning the lottery, it is not completely impossible. The adjustment of the course is also because the aircraft itself is too small and is easily affected by the gravity of the surrounding stars. On the scale of the universe, a small deviation may cause a complete error in the route after hundreds of years. The middle of the aircraft is the main exploration device, which has more than 20 light sensors on its surface, including cameras, and multiple gravity sensors and a centralized micro host inside. The computing power of the host is only 10 billion times that of a 21st century mobile phone. It is responsible for drawing the surrounding star map and transmitting it to the tail end of the aircraft. The tail end of the aircraft is a signal transmission device, which transmits the information it obtains to the Federation behind. Not only that, there is also a kinetic energy system inside the aircraft itself. This kinetic energy system is not only used for transmitting information and supplying energy to the host, but also for preparing for the factoryization of the entire aircraft in the future. These sub-light-speed aircraft are also ultra-small micro-factories. After completing their mission, they will find a nearby star system and enter it, landing on the surface of a planet or asteroid to start construction. "How many sub-light-speed aircraft are planned to be launched around?" Yan Xia asked.
"About billion, Yan Xia!" Ella said billion not because more can't be launched, but that these are enough. These sub-light-speed aircraft can detect a large range of starry sky through optical detectors, and there is no need for repeated launches. "Well, after controlling the information within 5,000 light years, our other plans can also be implemented." Yan Xia looked at the starry sky. He wanted to take advantage of all the advantages of the current federation.
