Eric spent a lot of money to build such laboratories and well-paid experts not to show off how rich he was, let alone to show them the usefulness of computers, but to cure the energy diseases of the Federal Republic of Germany.

The rapid development of Germany is not without restrictions, the lack of oil Germany needs to use a large amount of coal liquefaction to make up for the gap, although the cost is higher than the purchase price of crude oil, but Eric has not given up this development, still a large number of purchases.

At this time, Germany experienced the industrial revolution after the use of electrical equipment for production and rest, the main source of electricity in Germany is thermal power generation, water conservancy and wind power generation scale is very small.

In this context, Eric came up with the idea of using nuclear energy to generate electricity.

The theoretical basis is the last thing Eric lacks, and the reason why so many scientists are gathered together is also because of the inevitability of scientific development, otherwise the ready-made theory will constrain sporadic thinking.

And the No. 13 Institute of Physics is only a place to provide research theories, and the place where nuclear energy is really developed is not here, but the No. 14 Institute of Physics, which Erick built separately, is completely isolated from the outside world, and there is also a computer inside, which is much better than that placed in the No. 13 Institute of Physics.

The research plan of Institute No. 14 is "Pandora 1", and Institute No. 13 provides only the necessary theoretical basis.

After all, the theoretical basis is only paper data, and it is certainly not an overnight thing to really want to implement, and Eric does not want to leak too much secrets, so the progress will not be fast. The raw materials and equipment needed could only be carried out quietly, experimenting on a small scale without interfering with the existing normal order.

Eric accompanied the research team around to the first floor, and just as they were about to go down, Eric made an excuse to leave.

"Go to Research Institute 4." Eric instructed the driver.

Half an hour later, Eric's car, along with a dozen cars, stopped in front of the institute marked No. 4, where the guards checked everyone's identity after seeing that it was the president himself.

If nuclear power generation is Eric's main concern right now, then the results of Research Institute No. 4 have given Eric hope.

Research and development focus No. 4 is on rockets.

In 1916, the 4th Research Institute had already used alcohol as fuel and liquid oxygen as an oxidizer.

Towards the end of the war in 1918, Eric did not intend to involve rockets in the war, which was too inefficient. With the outbreak of war and the advancement of science and technology, materials science ushered in another advance, and the R&D team began to try to use other fuels as alternatives.

The XCOM-FB-1 engine is the second liquid fuel engine after alcohol, and uses liquid hydrogen as fuel.

The hydrogen-fueled XCOM-FB-1 rocket engine did meet Eric's standard for the ultimate room pressure for testing, even exceeding it by a factor of four to more than 30.

However, for Germany now, this excess is not a good thing, and the excessive room pressure makes the material unable to withstand the pressure and disintegrates directly, and the XCOM-FB-1 program is once again shelved.

In order to solve the fuel problem as soon as possible, the R&D team had to choose a very modest fuel, kerosene.

Eric didn't say much, only reminded the R&D team that kerosene should only be used as an over-fuel.

The reason why Eric thinks kerosene is an excessive fuel starts with the same chemical that kerosene comes with, a corrosive chemical, sulfur.

Corrosiveness is also an inferior chemical that severely limits the performance of rocket engines, and scientists working on rocket engine design would rather not need this substance in their designs.

Simultaneously with the use of kerosene, scientists also began experimenting with a household fuel, methane.

In the end, the two plans were opened at the same time by Eric's big pen, and the funding instantly hollowed out the Eric Group. As a last resort, Eric had no choice but to finance these two projects and bring the Wehrmacht in.

This programme was immediately initiated with the integration of substantial funds from the Defence Forces.

Returning to the problem of kerosene, in the new design, the turbopump of the liquid rocket engine is very afraid of carbon deposits, and the carbon deposits of kerosene seriously affect the working stability of the turbine, so the R&D team had to adjust the gas generator efficiency of the liquid oxygen kerosene engine in continuous tests, from 65% all the way to 35%.

This efficiency is frighteningly low, equating to only 35% fuel usage.

If this efficiency was only used as a weapon in the atmosphere, the new XCOM-FBK-1 kerosene rocket engine already met the requirements of the Wehrmacht.

But Eric doesn't want to stop there, he wants a rocket that can make a rocket out of the atmosphere and into space.

Inspired by the radar scanning function used many times in the rescue chamber, Eric also desperately wanted to give Germany the ability to observe global dynamics during this time, although this requirement could not be achieved for a while.

If you want to send satellites into space, you can't use the XCOM-FBK-1 kerosene rocket engine, and Eric has to find another way to solve it.

It was at this time that the friendship between the Soviet Union and Germany, as well as the renewed arms sales orders between the two sides, gave Eric hope, that is, Soviet kerosene.

Kerosene from the Baku oil field in the Soviet Union was the main choice of aviation fuel in the late Soviet period due to its low sulphur content. With Eric's help, the Soviet Union's low-sulfur kerosene was quickly delivered to the laboratory, and it took less than half a month, and the laboratory quickly adjusted the design according to the latest kerosene.

Based on the XCOM-BFK-1, the low-sulfur kerosene allowed the R&D team to continuously increase the efficiency of the gas generator, from 35% to 51%.

Eric then proposed an engine cooling channel on the improved XCOM-BFK-2 to allow the liquid to flow through the hood to reduce the temperature while heating the fuel for greater efficiency.

It's just that it is still limited to the lack of suitable superalloys and high-temperature resistant layers, although the XCOM-BFX-3 model has made a lot of progress and can be used for military purposes, but there are still some gaps in the requirements for Eric to take off.

So the R&D team came up with a simple and crude method, if one can't do it, then several will work together.

Although this method may seem crude, it is actually a remedy, but unfortunately, through experiments, it has been found that simply bundling a few engines together does not increase the power as they hope, but rather more problems.

First there is the ignition problem, then the streamline problem, and then the orbit calculation problem.

After learning the news, Eric only sighed in the office: "This is the real science, progress will also encounter more problems, human beings can solve more problems until they achieve their wishes." ”

The reason why Eric is coming to Research Institute No. 4 today is to solve design problems other than materials, and some problems about orbit measurement.
