Huang Haojie saw the report from the institute's management committee, saying that the Academy of Sciences wanted to purchase a prototype machine for research.
After thinking for a while, he decided that since Dongtang had already agreed to purchase two Jinwu-1s, there was nothing wrong with selling the prototype to them for research, so he approved the matter.
After reviewing some important documents, he directly launched the anthropomorphic bionic robot at the secret research institute in Keelung.
In fact, after Liu Jingguan proposed the neutron pressing motor, Huang Haojie has been conducting related research.
In a laboratory of the secret research institute, with the assistance of Zhong, Huang Junjie was injecting dd solid (produced through the submetallic hydrogen method) into a miniaturized neutron pressing reactor.
This small neutron squeezing reactor is spherical in shape, about the size of a football.
The football-shaped condensed matter vacuum chamber inside is wrapped by a ring-shaped vacuum pipe. This ring-shaped vacuum pipe is made of mixed gel materials. The outside is a circle of conductive coils. One-fifth of the volume of the ring-shaped vacuum pipe is contained inside.
Metal sodium.
He turned on the holographic computer and pressed the reaction switch.
The working principle of a small neutron squeeze reactor is exactly the same as that of a large one, including injecting nuclear fuel, compression, energy release, and ash discharge.
However, there is definitely no way to install a steam turbine in a small neutron squeezing reactor, or even a laser electric pipeline.
The small computer in front of Huang Haojie uses a magnetically permeable fluid electrical system, which directly uses light radiation and direct heat to heat metallic sodium to form sodium plasma electricity.
However, the DD nuclear fuel in this reactor is only 0.1 gram, which is also 100 mg.
Deuterium atoms account for 98% of 100 mg dd solid nuclear fuel. After nuclear fusion reaction, it can theoretically produce about 8500 kilowatt-hours of energy. The reaction time is about 1800 seconds, and the average power is about 4.72 kilowatt-hours per second.
However, Huang Junjie's real-time monitoring data at this moment shows that the power is between 1.32 and 1.34 kilowatt hours per second, which is only about 28% of the theoretical energy.
The reason why the energy conversion efficiency is very low is that the thermal energy utilization rate is too low.
In the nuclear fusion process of small computers, in order to reduce weight, currently only magnetic hydroelectric systems can be used.
In the magnetic hydroelectric system, 56% of the light radiation energy needs to be converted into heat energy first (light radiation heats metallic sodium). In this process, the energy conversion efficiency is about 8o%. After this round of conversion, it becomes 44.8%.
thermal energy.
Light radiation converts 44.8% into heat energy, plus 27% direct heat energy, the total amount of heat energy that can be utilized is 71.8%.
The heat energy utilization rate of the magnetic fluid motor is about 40%, and only about 40% of the converted electrical energy is left, and the other energy is wasted.
Huang Junjie looked distressed at the hot minicomputer in front of him. This minicomputer was heating up crazily due to the unusable heat.
If the materials used were not very strong, the fuselage's high temperature of 742 degrees Celsius would almost melt steel.
Large neutron squeezing reactors can use steam turbines to utilize this heat, but small machines cannot install steam turbines.
The refrigeration equipment in the laboratory uses more electricity for cooling than electricity. Even if it is installed inside the mecha, it can dissipate heat through natural air cooling and consumes a lot of electricity.
Obviously this heat energy is not only wasted, but also becomes a burden.
"Abort reaction."
[receive.]
Drop! The pressure inside the vacuum chamber suddenly dropped rapidly, and the nuclear fusion reaction was stopped.
Hiss! A stream of refrigeration spray enveloped the minicomputer.
The nuclear fusion reaction created by the neutron squeezing method can be stopped at any time and at any time, and it is very safe even if the system fails.
If the condensed matter vacuum chamber fails, the nuclear fusion reaction will not occur; if there is a failure during the reaction, once the condensed matter vacuum chamber fails and there is no pressure to squeeze, the nuclear fusion reaction will immediately produce neutrons; and the dd nuclear fuel itself
It is non-radioactive, and the product helium is also non-radioactive.
The most likely danger is the leakage of high-temperature plasma that has lost its suppression, but at most this will cause some equipment to be burned out.
Especially for large-scale neutron pressing reactors, personnel are not allowed to enter the core area during operation, so even if an accident occurs, the risk is very low.
Huang Junjie ignored the cooling minicomputer and turned around to look up information on the holographic computer.
He must find a way to deal with this unusable heat energy, otherwise the miniaturization of the nuclear fusion power system will be useless.
Especially when installed on a mecha, those infrared monitoring devices can sense such a large amount of heat energy at once.
Enter the keyword search [heat, electricity, recycling] into the holographic computer, and soon a lot of information pops up.
These materials are available at home and abroad. They are internal databases collected by Zhongbang. This database can be said to be the largest scientific research database in the world.
After some searching, quite a few pieces of information came into Huang Junjie's sight.
Among them, [ion motor], [photon motor] and [thermoelectric] were highlighted by Huang Haojie.
The reason why the ion motor is focused on by him is mainly because the ion motor can directly utilize nuclear fusion helium ash and use the photothermal energy of nuclear fusion to heat inert gases.
Helium plasma and heated inert gas plasma are ejected, and in this way reaction force is generated to push.
The photon engine uses the light radiation produced by nuclear fusion and then reflects the photons through the mirror. This method is similar to the ion engine.
Ion motors and photon motors will play a very important role in future spacecraft, and each has its own advantages in application.
Ion motors can use helium gray exhaust gas, but light radiation requires secondary conversion; while photon motors can only use light radiation and cannot utilize heat and helium gray exhaust gas.
And whether it is an ion motor or a photon motor, it is very unsuitable for use in the atmosphere. They have a congenital flaw. The thrust is relatively small compared to chemical power. Even if nuclear fusion is launched, it is still difficult to cover up their congenital flaw.
Photon motors and ion motors are only suitable for use in outer space, especially long-distance outer space, because their ratio exceeds 10,000, and they can continuously increase the flight speed to a very high level, which is difficult to achieve with chemical power.
If the current Qinglong-class spacecraft is filled with fuel, goes out to Mars from the Blue Star synchronous orbit, adds a gravitational slingshot, and calculates the position and time (the closest distance between Blue Star and Mars is about 5.5 million kilometers), the spacecraft can reach about 16 kilometers per second.
.
At this temperature, it will still take approximately 4o to 42 days.
If a synchronous orbital mass projector or a lunar mass projector is used, the speed can be increased to about 40 kilometers per second, and Mars can be reached in 15 days at the fastest.
If a photon motor or an ion motor is used, adding it to the mass projector, and then continuing to use the motor to propel it, it is estimated that it can reach Mars in about 10 days at the fastest.
But these applications are only suitable for outer space. In the atmosphere, flying with a mass of 1 ton with a little thrust is enough, let alone using ion motors or photon motors to go to outer space.
