"Then I’ll tell Lao Li."

Although Eagle Aerospace is a private company, the space agency and private company are close, and there are both competitions and mergers between them, so there is no need to avoid suspicion.
This kind of rocket transport by plane backpack launch also has a similar project abroad. They don’t have the big load transport function to transport small rockets.
However, the state-owned super-large Hefei Peng class will send rockets as high as 3 kilometers after it can be transformed.
To some extent, the most fuel-consuming stage of rocket transport is that the troposphere and stratosphere in the atmosphere consume a large part of fuel.
The somersault cloud project is to save fuel in these two areas.
In fact, this model can also be used as a rocket core level, which can be quickly repeated many times
Chapter four hundred and ninety CSi nanocrystals
Wenchang launch site and Academician Wang and others discussed for a long time. Huang Xiuyuan put the body double robot in a special escort team and quit the virtual system
Shanmei head office 1 ST scientific research zone
He came to Lab 6 of Institute 155.
Recently, Huang Xiuyuan has been working in this laboratory. The research project of this laboratory is laser crystal, that is, solid-state laser.
China is actually in a relatively leading position in the research and development of solid-state lasers. KBBF (Potassium Boron Beryllium Fluoride) crystal developed by Academician C.T. Chen is a special material that China has strictly controlled for a long time.
KBBF crystal is a kind of nonlinear optical crystal material, which can convert other light waves into deep ultraviolet microscope and mask aligner surface.
Huang Xiuyuan intends to develop a very important laser crystal in the future-CSI nanocrystal, which is also developed by a future academician of China. This crystal is a material similar to KBBF crystal, but there are some differences between them.
KBBF is specialized in exciting 167 nm deep ultraviolet light, while CSi nanocrystals are specialized in exciting far infrared light.
Laser weapons usually make far infrared light in long waves instead of visible light and short waves.
CSi nanocrystals are specialized laser weapons. From the name of CSi nanocrystals, we can know that its raw materials are carbon and silicon, while the technology is nano-technology.
From the near-infrared high resonance effect of gold nanorods, we can know that the resonance effect of the same substance, the fixed form of gold and the special nanometer state, on specific light waves is very different
Similarly, ordinary carbon crystals and silicon crystals are not high-quality laser materials.
However, Huang Xiuyuan rearranged the carbon and silicon nanostructures to form two special nanostructures through nanotechnology adjustment.
One is that the carbon 24 fraction is completed by the superposition of two 12-sided shapes, and then the carbon 24 fraction is combined through a special process to form a carbon film.
The other is to divide the silicon into triangles, which must have a characteristic that the three angles of the triangle must be 27, 54 and 99.
Then triangular silicon is filled into the carbon film, and the thickness of the carbon film is continuously superimposed until the thickness of the film is superimposed to 17 mm, so that the crystal can be excited by solid-state laser.
The reason why Huang Xiuyuan attaches great importance to this crystal is that this crystal can not only stimulate far-infrared light CSi nanocrystals, but also has another advantage, that is, the light conversion efficiency is extremely high, reaching an astonishing 96%
At present, the light conversion efficiency of various types of lasers in the research and development of laser fields around the world is uneven, ranging from 1% to%
For example, fiber laser Yb-doped semiconductor pumped fiber laser (pumping wavelength 9 n) is lower than Nd-doped YAG diode pumped laser (pumping wavelength n).
The optical conversion efficiency of fiber laser is usually 7% ~ 7%; Pumping YAG is only about 4%; Semiconductor pumped YAG and disk laser are about 4%; The optical conversion efficiency of CO2 gas laser is only about 1%.
At present, laser weapons, long-distance laser weapons, most carbon dioxide lasers, the optical conversion efficiency of which is about 1%, know the shortcomings of this laser.
9 kilowatts of laser emitted from 1 kilowatt can be turned into waste heat and line loss, which is washed away.
This not only wastes energy, but also increases the difficulty and makes it difficult to increase the laser power.
CSi nanocrystals are actually fiber lasers in solid-state lasers.
All the high light conversion efficiency of fiber laser is due to the fact that the laser is eventually included in the fiber crystal, so the laser cavity will not cause the laser loss factor.
It is difficult to make the front fiber laser large, which is at most the size of a laser pen.
However, CSi nanocrystals have changed this defect and can be made very huge, and the output power can be increased by expanding the area and increasing the thickness of CSi nanocrystals.
In front of Huang Xiuyuan’s experimental platform, a cylindrical CSi nanocrystal with a radius of 5 cm and a length of 1 decimeter is displayed.
Several experimental assistants carefully held the crystal and prepared it in the laser before installation.
The other circuit of the laser adopts the recently developed point superconductor cooling system to cool the temperature to minus five degrees Celsius.
Huang Xiuyuan ordered "Prepare to start the laser test"
"white"
One side wall of the laboratory slowly reveals a testing ground.
A target surface is raised in the researcher’s drill test field with label 1.
When the researcher presses the laser launch button, a color far-infrared light in the laser with a length of more than three meters directly hits the center of the target.
In less than 2 seconds, a fist-sized melting hole appeared on the iron plate target with a thickness of 5 cm.
Huang Xiuyuan calmly ordered "change the target"
"yes"
The researcher also replaced a wooden board target and was instantly penetrated by the laser.
Then they tried whether the lasers of glass, plastic, ceramics, reflective materials and composite materials passed the frequency modulation or penetrated these targets one by one.
Then the distance test shows that the longest distance can be 35 meters, which is easy for far-infrared laser.
Huang Xiuyuan estimated that according to the current test data, the atmosphere of this laser should be able to be quickly destroyed at a specific shooting distance of about 5 kilometers, and further tests are needed.
If the distance is too long, the scattering power will gradually decrease.
