Chapter 1774 Inspection

    This is also thanks to the fact that Qin Baoshan liked military knowledge very much in the original time and space, and he also dabbled in these navigation knowledge, so now he can speak with flying stars, and he looks like the most professional person.  In fact, he can only talk about these basic principles. If it involves specific circuit structures, then his eyes are really in the dark.  He still wanted to continue talking, but Xiong Zheng and Lu Da no longer listened to him.  These two people got the first principle and already thought of how to solve this problem.  They also don't need to listen to what Qin Baoshan said next, after all, that kind of navigation is all-round, and they don't need it.

    Now that Qin Baoshan has come here, he has settled the radio navigation issue, and what to do next is up to Xiong Da and Lu Da.  Qin Baoshan will not pay attention anymore, he has confidence in these two people.  After all, apart from the two of them, there are more people who have come to the arsenal together, and many of them are intellectuals.  These people must be able to solve specific technical problems.

    Of course.  Now that he's here, Qin Baoshan won't leave immediately. He inspected the Xiagou Iron Works.  In the past, only white pig iron from the Taihang Mountains could be produced here.  It just turned an ordinary blacksmith's shop into a large ironmaking furnace.  But now, there has been a complete shotgun change here.  Some of the white pig iron produced from the iron-smelting furnace will be directly made into the casing of the grenade, and some will be processed into the ammunition of the grenade.  Others will enter the steelmaking furnace and be smelted into steel through the oxygen top-blown converter.

    It was precisely because of the set of oxygen-generating equipment brought back from Beiping that this big problem was solved.  The oxygen produced here can not only meet the needs of smelting steel, but can also be used by bombers.  When the plane is at low altitude, it is enough to directly breathe the oxygen in the air, but when it reaches high altitude, it has to inhale oxygen.

    The oxygen in the plane, of course, must be pure oxygen.  This saves the most volume. Otherwise, the volume would be too large if ordinary oxygen air is compressed and poured into the steel cylinder. Although the oxygen cylinder contains pure oxygen, it does not mean that the pilot must have pure oxygen.

    When the pilot is in the air, he can manually select the oxygen supply mode of the oxygen system. When the switch is placed in the "pure oxygen" position, pure oxygen will be provided; when the switch is placed in the "mixed oxygen" position, what the pilot inhales is close to natural  state of mixed oxygen.  Just mix thin air in and that's enough.  Therefore, the pilot does not need to breathe pure oxygen completely.  How to inhale oxygen depends on the pilot's own choice.  If a fighter jet is engaged in air combat, inhaling pure oxygen can allow the body to receive more oxygen to meet the needs of intense exercise.  But bombers don't have that kind of requirement, they usually use ordinary oxygen.  Even if it is inhaling pure oxygen, as long as it is inhaled for a short time, it will not cause harm to the body.

    The advanced steel produced can be used in a variety of ways.  There is a special steel rolling equipment next to it, which can directly press the manufactured steel into iron plates, so that it can be rolled up to become a multiple rocket launcher.  In Li Yunlong's use, the multiple rocket launcher has already exerted tremendous power, so this weapon is now in the low-speed production stage.  After all, even if it is a rocket launcher, it is small and flexible, and will not cost too much.  But the rockets needed are too wasteful, and the Eighth Route Army cannot afford to be equipped with a large number of rockets.  It can only be equipped in small batches for elite troops.

    In addition to producing various iron plates, it is also necessary to repeatedly beat the steel with a hydraulic press to turn it into the best steel for making gun barrels and gun barrels.

    In the process of steelmaking technology development, electroslag remelting steel is a very important invention.  The steel is re-melted through an electric current, and the slag is suspended above the molten steel, and the more perfect steel is obtained below.  This technology is also necessary for the manufacture of various advanced gun steel.  It's just that for the Eighth Route Army, there is no such demand at present, and there is no large amount of electricity that can be used to smelt steel, so Qin Baoshan never mentioned this plan.

    The steel with the best quality is also used to make bullet casings. This is also a good invention, which greatly reduces the demand for brass and is a key technology for the Eighth Route Army to increase production.

    After wandering around to the end, Qin Baoshan saw a batch of parts.  At the beginning, he proposed to imitate the simplest single-cylinder engine to make more paragliders.  After receiving his request, Lu Da and Xiong Zheng conducted a lot of basic research, and now they have produced many parts.  The most critical engine block parts have been fabricated.  Pistons, connecting rods, and crankshafts are also on the side.  In particular, there are several manufacturing samples of the piston, one of which is still aluminum alloy.  Such a small engine must be air-cooled.  It is estimated that the cylinder part will be made of aluminum alloy in the future, which is more convenient for heat dissipation.  due to manyThe parts haven't been manufactured yet, so final assembly will have to wait until later, and some of the components will even have to be procured.  So right now these are in a semi-finished state.

    But looking at these semi-finished parts, Qin Baoshan was very satisfied.  Once the Eighth Route Army can manufacture its own engines, that would be a great improvement.  In addition to being equipped with paragliders, it can also be equipped on motorcycles.  It would be nice to have a motorized army first.  And after solving the problem of availability, we can produce more powerful engines in the future.  It is possible to build cars, and even tanks.

    Qin Baoshan was looking forward to the future, and the day passed like this.  At night, the American telegram finally came back.  The content of the telegram is very simple, to approve Qin Baoshan's request.

    Qin Baoshan wants to use American bombers to bomb the Japanese mainland. Given that American pilots are unwilling to fly bombing planes, of course he can hand over this matter to Qin Baoshan.  Anyway, that bomber was repaired by Qin Baoshan and the others, and now it is idle in the Eighth Route Army.

    After receiving this telegram, Qin Baoshan was not too excited, because he had already guessed the result.  It's just a bit long waiting for the reply from the headquarters of the Eighth Route Army.

    If Qin Baoshan didn't go, but other people, he would probably have given instructions already.  But Qin Baoshan's safety is too important. Now that Qin Baoshan is going to carry out this mission with him, the Eighth Route Army Headquarters has to think carefully.  Does Qin Baoshan need to take this risk?

    In this way, time passed day by day. On the third day, Qin Baoshan couldn't bear it anymore and decided to go to the headquarters of the Eighth Route Army in person.  He brought the prepared blood letters of the flight crew, and he couldn't believe that the superiors didn't agree.  (Remember the site URL: www.hlnovel.com
