This achievement is of great aerospace significance.
In general, the so-called large UAV near space is actually a suborbital UAV. Although this drone did not go into space, it flew at an altitude.
At about 100 kilometers, it is far beyond the flight altitude of ordinary aircraft. Therefore, it is of great significance in aerospace and scientific research. Specifically, it has these significance: it has aerospace value, it has mapping value, it has military value. The following author will explain these in detail:
Clause. 1. China's successful first flight of a large UAV near space has aerospace value: because this large UAV has seven solar cells and can last for a long time at an altitude of 100 kilometers, it can detect and study the atmosphere for a long time.
environment, suborbital environment, and near-Earth space environment. Long-term detection and data acquisition through large UAVs.
Contribute to space research by gaining a better understanding of these environments and how they affect rocket launches and manned spaceflight, and the large drone can also be used as a space station.
Information relay role. Able to build information bridges. It can be seen that this large UAV has great aerospace significance.
Clause. Second, China's successful first flight of a large UAV near space, the significance is that it has surveying and mapping value: because of all surveying and mapping operations, high-altitude mapping is the most comprehensive and detailed, especially for a large area of territory, and this large UAV is at an altitude of 100 kilometers, even higher than the aircraft, so at this height can be China's territory, coastline, geography and the whole picture.
This is of great significance for surveying and mapping.
Clause. 3. China's successful first flight of a large UAV near space has military value: although the range of activities of China's large UAV is limited to China's volley, in terms of its height, it can take in most of the world.
No matter what changes there are in other countries, they can be observed, so they can play a military early warning role, and this kind of military early warning has great military significance.
-
This result is a new step forward for China's drones, and it allows us to use drones in all fields.
-
The flight of unmanned aerial vehicles (UAVs) has made further development of China's big science and technology and realized the automation of China's flight industry.
-
Because space technology is the exploration of the universe and the progress of a country's science, it is necessary to attach importance to development.
-
Because we are looking for new places to live, to see which planets are habitable, and whether there is water and oxygen. So that we don't have to worry about humans going nowhere in the future.
-
Because it pushes the boundaries of technology, and the resources in space are terrifying. Moreover, the aerospace level is also the embodiment of comprehensive national strength.

C. Test Question Analysis: This question examines the content of New China's scientific and technological achievements. With the development of science and technology, the only countries in the world that have manned spacecraft technology and successfully achieved flight are the United States, the former Soviet Union and China.
Neither Britain nor India has achieved the flight of manned spacecraft. Therefore, the answer is c

From the relevant news, we can see that China has tested a drone uh, a very powerful drone, in this case, it is a drone that uses solar power to generate a uh as kinetic energy, what kind of practical value does this drone have? Next, let's take a closer look. <>
From the related news on the sakura we can see that ah, this kind of solar power generation of a drone is a success, for a scientific research field in our country, has a positive and good promotion effect, ah, its use value is very much, in general, it has a great positive effect on agriculture and meteorology and medical and health at the same time for emergency rescue and disaster relief, and to a large extent, As long as there is a sunlight, it can continue to fly, in this case. Well, it's a very good phenomenon. <>
In general, one of our country's UAVs is a success in flying, it is a very good phenomenon, it is also a big change for a military field in our country, first of all, in the military field, it needs this kind of temperature machine reconnaissance, especially on the sea surface, to a large extent, it is necessary to be like this kind of UAV existence, if only by airplanes and ships, then to a large extent, The consumption of energy and the consumption of manpower are very fatal, so we all need to understand that the practical value of this drone is very high, especially in the military field. <>
In addition, this kind of drone is very good for a forest fire prevention, because now a forest fire is very serious because of the existence of dry weather, so we all need to develop this kind of drone to provide an effective avoidance for this kind of fire. Well, this is a very important point, and in this case, it also has a very important significance for the fire prevention of the forest.
-
The biggest value of this drone is that it is used for detection, and it is very cost-effective because of its high range and low cost.
-
I think drones can survey dangerous areas, such as mountains, and deliver supplies to those who are affected by disasters.

As an unmanned transport aircraft for export, the export application is broad. It can bring great commercial value to logistics and transportation in remote areas.
C919 is cattle for the following reasons:
1. There are only three companies in the world that can produce C919 passenger aircraft, Boeing in the United States, Airbus in Europe and Tu series in Russia. But the most widely used airliners in the world are still Boeing and Airbus, and basically all the planes in the world are produced by these two companies. If China can produce it, it will be the third passenger aircraft in the world that can be used on a large scale. >>>More
The successful test flight of China's aerospace aircraft is certainly a big step forward for China's aviation. The space shuttle is operated on the basis of the original space shuttle, but the space shuttle can only fly in the atmosphere, while the space plane can combine aviation and spaceflight, and can fly in the orbit of the solar system, providing a more economical and convenient way for the earth and space to travel back and forth, and of course, reducing the formation of space junk. In short, the successful test flight of China's aerospace aircraft is a big step taken by China's aviation, and it is expected that the development of China's aviation will get better and better. >>>More
On December 30, 9999, 12:59:59, the moon exploration was successful!
Common centipede breeding**1, centipede egging**Some information or**claims that centipedes lay eggs 3-4 times or 2-5 times at conventional temperatures, with more than 80 eggs each time, and some also claim that each egg is more than 100 grains, which must be false. Centipedes lay eggs once a year at regular temperatures (4 distinct seasons a year), with 30-80 eggs each time. The annual constant temperature is 25-35 degrees, and it can lay eggs 2-3 times in 2 years. >>>More
In addition to tea, China still has many successful cultural exports, such as kung fu, tea ceremony, and porcelain. Moreover, many literary works in my country have also been sought after by foreign countries, such as the four famous novels, "Journey to the West" and "Romance of the Three Kingdoms". >>>More
