"The 54 DH-10s of the wing must be changed, and even the six training planes used for training must also be changed. If you need anything, you can send an order to Commander Wu, and we can buy it abroad as soon as possible, and I hope that this improvement work can be completed by the end of the year. In addition, I think there are a few things that need to be improved. ”

Song Zhewu picked up a pencil, brushed a few strokes on Mike's drawings, ticked off the rear cabin, and added a sliding transparent hatch to the open cabin on the front cabin.

Song Zhewu put down his pen and said: "With the surname of DH-10, if you add the aircraft gun, it already has a certain self-defense capability, and the original two machine guns are not very useful, so I think it will be canceled." Not only can it save space, but it can also increase the payload; In addition, some improvements were to be made to the aiming gear. As far as I know, the current Star Ring mechanical sighting rig does not work very well. When I was in Germany, I heard that there were already people working on pre-calculated optical gyroscopes and semi-automatic calculated optical bombing sights, which were said to use gyroscopes and semi-automatic calculations. Although I do not know the technical details of this sighting device, I think that such an aviation sight is composed of nothing more than the following parts: a parameter measuring device, a calculation device, and a display device. The parameter measuring device measures the parameters required for aiming calculation, such as target motion parameters, local attitude and motion parameters, and atmospheric parameters. The calculation device is based on the measured data and the data pre-installed by the pilot, such as ballistic parameters, target wingspan, etc. Aiming calculations are carried out to determine the initial firing state and projection timing required for the ammunition to hit the target, and the calculation results are sent to the display device for display. Based on the target, aiming mark, and relevant information observed on the display, the pilot swoops the aircraft or the onboard weapon, so that the aiming mark coincides with the target, and the aiming is carried out. ”

This optical gyroscopic sight only appeared in the late 30s, and Song Zhewu, a master of chemical engineering, is not clear about its specific structural principle, only to see Guo Wenyuan's ability.

In fact, Song Zhewu still had some problems in the structure of the aircraft that were ahead of this time, such as the problem of the wing. At this time, the wings are divided into shapes, and the commonly used ones are rectangular wings and trapezoidal wings; In terms of quantity, there are single wings, double wings, three wings, and even more. And Song Zhewu knew that in the end, it was all monoplanes and delta wings, and they were swept wings. Modern aircraft are also equipped with flaps to improve take-off and landing, ailerons for lateral longitudinal longitudinal of the aircraft, and some are also equipped with slats and other lifting devices on the leading edge of the wings.

It's just that these epoch-making improvements, when his own aircraft factory has not been established, and even when his aircraft surname can not reach the best and most advanced, he will not put it forward, even if the output is not large. He wanted to make sure that as soon as his plane appeared, his advanced surname would have an advantage over his surname.

Song Zhewu ignored the surprised eyes of Mike and Guo Wenyuan, and then said, "Give this optical sight to Wenyuan." I think that's the way to improve things. However, if you design a new aircraft, you have to use all-metal, like the J-10. I'm just giving you a question, how to do it, that's a matter for you experts. It's just that what we just said is the secret of our Fourth Route Army, and these must not be known to outsiders, understand? ”

Song Zhewu's series of almost new aviation thinking surprised Mike and Guo Wenyuan, and they didn't understand how Song Zhewu, a graduate of the Army Military Academy, had mastered so much advanced aviation knowledge! These new aviation ideas, which are almost a generation ahead of their time, must not be known to outsiders, especially large aircraft companies like Curtis, otherwise they will definitely develop advanced aircraft ahead of them due to their superiority in technology and their own equipment. This point, Mike and Guo Wenyuan can think clearly.

Mike also asked Song Zhewu again, and at this time, a staff officer of the corps came over to report to Wu Jin, "The six assembled planes that were originally scheduled to be tested today have been pulled up to the runway, please ask Wu Jin if he is still flying as planned." Wu Jin looked at Song Zhewu with inquiring eyes.

As soon as he heard that he was going to test fly, Song Zhewu immediately said happily: "Okay! It was a coincidence that I had a test flight today as planned. ”

Wu Jin said with a smile: "Commander, you are wrong, originally the first test flight of the DH-10 was to invite you here, but I have been really busy seeing you in the past few days, so the test flight has been postponed until now." I know that the commander will not forget our Air Force Corps, and I have told them that we must be ready for test flights at any time, and as soon as the commander arrives, we will start test flights. ”

Mike also listened to Guo Wenyuan's translation at this time, and he also said excitedly: "Commander-in-chief, the trainer plane that Guo and I modified has also undergone our final inspection just now, and it also needs to be tested for flight testing, so let's even test fly it together, right?" ”

"If both of you confirm that the plane can fly, then I'll agree." Song Zhewu looked at Mike and Guo Wenyuan inquiringly.

Seeing that both of them nodded, Song Zhewu waved his hand and said, "Okay!" Let's test fly together. ”

Mike and Guo Wenyuan immediately instructed the technicians on the scene to install the lower guard plate of the training aircraft and refuel. After all this was done, someone removed the movable wall of the shack and the training plane was pulled onto the runway by a truck specially allocated to the Air Force Corps as a tractor.

At the end of the runway, there were already six DH-10s parked, and Curtiss had sent a total of seven flight instructors including Mike this time, including Mike, who had already put on leather flight suits and carried umbrella bags to the plane. All around them, all the people who had no tasks at the airport had gathered far around the plane, and more than 90 percent of them were waiting to see the first time in their lives that they saw the plane take to the sky.

Song Zhewu suddenly remembered a question, turned his head and asked Mike: "The two runways of this airport are dirt, can such runways withstand the momentum of the plane when it lands?" ”

Mike nodded and said, "No problem, I have carefully checked the quality of the runway, it is much stronger than the runway of our field airfield during World War I." ”

After receiving Mike's affirmative answer, Song Zhewu was relieved, but he still asked Mike with doubts: "But if it rains, how does the plane take off and land?" Due to the rain, the soil of the runway will be very loose, and if the plane takes off, the runway will be crushed, and if it is landing, the slippery runway will bring great danger to the landing aircraft. ”

Mike shook his head and said, "Then I'll have to wait for the runway to dry and use it, there's no other way." ”

Cement Song Zhewu is not without it, he can go to Tangshan to buy it. Twenty years ago, Tianjin businessman Zhou Shufa purchased two sets of 2×20-meter hollow dry production equipment from Denmark's Smith Company, and built Qixin Cement Plant in Tangshan City, which is the first cement factory in China. The plant currently has 5 cement production lines, with an annual production capacity of more than 200,000 tons. Even he now has a small experimental rotary kiln in Laiyuan, which is mainly because Song Zhewu considers that once he has Shanxi, he will have to carry out a lot of construction, and the cement needs a lot. And he only knew the general structure of the advanced rotary kiln in the novel, he was experimenting, but now it should be successful, the output is more than 30% higher than the vertical kiln, Song Zhewu thinks that if some improvements are made, the output should be higher. It's just that now after all, it's an experimental surname, and the yield is still too small.

The most important thing is that Song Zhewu doesn't want to have a permanent airport in Laiyuan, Shanxi, and he can't guarantee that it won't be temporarily lost. If the army is allowed to have an airfield here, the threat to Shanxi is too great.

Seeing that Song Zhewu frowned and was silent, Mike said to Song Zhewu: "If we are stationed here for a long time, then we will still build a cement runway; If it is only for a while, then such a runway is enough now. Pointing to both sides of the runway, Mike said, "There are culverts buried there, which are designed for drainage, and when it rains, the rainwater will drain away quickly." If it only rains heavily for half a day, the plane will be ready to take off after a day.

Song Zhewu nodded, he knew that it was all over now.

Mike greeted Song Zhewu and Wu Jin and walked to his plane. Naturally, Mike is going to fly his improved trainer, and the effect of the improvement must be felt by himself.

Mike beckoned an instructor, and the two spoke, and the instructor shrugged, spread his hands, and climbed into the back cockpit of the trainer plane lined up in front of the runway. As soon as Mike gestured, the other five instructors also climbed into his plane.

Song Zhewu knew that this was the surname that Mike asked the instructor to test the trainer with him.

After Mike made a gesture, on the temporary tower made of wooden frames, one of the staff officers in charge of the command raised the red flag and waved it vigorously, and Mike's landline began to roar, and as the roar became louder and louder, the trainer began to slowly slide onto the runway.

The trainer plane drove faster and faster on the runway, in the middle of the runway, the fuselage of the trainer suddenly lightened, the landing gear left the ground at once, and then flew higher and higher, after leaving the ground more than 100 meters, the nose of the trainer aircraft suddenly warped, flew lightly to the air at a greater angle, and began to circle smoothly after drawing a beautiful arc in the blue sky.

Then, the other five DH-10s took off on the runway one by one, formed a formation over the airport, circled a few times, and then rushed straight into the sky under the leadership of the trainer plane. After burrowing into a white cloud, the group temporarily left everyone's sight. After a short silence, the crowd at the airport, which was watching the whole process of the plane taking off, suddenly erupted into a deafening cheer.

Most of these people don't say that they have seen airplanes, or more than half of them have heard of them, but now they are watching others assemble some of these objects transported to this airport, assemble them into airplanes, and then give them enough fuel to drink, and then people can sit in it and fly into the sky! It's easy to understand for students from Beiping and Tianjin, but for those young people who have been farmers for more than 20 years and can't live hundreds of miles before joining the army, it's amazing. They now have a great sense of pride in their hearts, the Fourth Route Army is the best army, and Song Zhewu is their best leader and commander.

Someone in the crowd shouted: "Long live Commander Song!" With this shout, a tsunami-like voice immediately sounded at the airport, 'Long live Commander Song!' ……”

Because Song Zhewu finally had his own air force, and watched it fly high into the blue sky, he couldn't control his excitement at this time, not only was his heart surging, but his blood was boiling. If it is said that when he just crossed over, Song Zhewu just relied on his patriotic enthusiasm and tried his best to use his own strength to make the nation and the country suffer less, at that time he just wanted to do his best. But now, under such a warm scene, Song Zhewu couldn't help but secretly vow, 'He doesn't want to do his best, he must kill the little devils to the ground, beat them all the way to their hometown, destroy their HG, and demolish their ghost society......

In the following days, Song Zhewu plunged into the teaching corps, although Xiao Guodong led the team to meet Zhao Pilian, Tao Rong was responsible for the reorganization of the army, and he didn't have to worry about it. Since the Fourth Route Army had already been reorganized twice, Xiao Guodong and the people in the staff department were very experienced. This time, Tao Rong presided over it, which was very efficient, and it was extremely smooth in all aspects such as personnel arrangement and weapon configuration. Officers of units that have been reorganized in advance have already begun to enter the training corps one after another, waiting for rotational training.

Song Zhewu is not worried about coming here, Li Wentian and Xu Zheng cooperate very well, Li Wentian is mainly responsible for the formation of the officer training corps, and the reorganization of the teaching corps is basically only done by Xu Zheng alone, although this is the case, Xu Zheng handles it in an orderly manner. Song Zhewu came to teach the corps, but he just wanted to discuss the training plan with Li Wentian, saying that it was a discussion, but in fact, Song Zhewu was not at ease. Although Li Wentian has an academic degree from the Baoding Military Academy and more than 10 years of actual combat experience in the army, after all, due to the restrictions of the times, some tactical issues may not be very advanced.

As soon as he arrived at the teaching corps, he was just in time for Li Wentian to look for him. Li Wentian's training plan and training outline have been completed, and he wants Song Zhewu to check and approve it. This plan was made by Xiao Guodong, Tao Rong, and Li Wentian, of course, Li Wentian was the main person in this matter, because the two of them were so busy these days that their feet did not touch the ground.

Song Zhewu was very satisfied with the training plan and outline, and not only did he receive training in various tactical subjects for army operations, but also the guiding principles for formulating strategies, and the Fourth Route Army's characteristics of three fierce, three fast, and two-sided aspects were further strengthened in the training plan. It's just that Song Zhewu feels that this plan is still a little insufficient, that is, it is too regular, Zhengda and stable. Although the support of the army emphasizes the main soldiers, the odd soldiers are supplemented. However, it is easier to achieve unexpected results in a short period of time if the surprise soldiers are used well, and even the weaker side can defeat a strong enemy.

Song Zhewu and Li Wentian repeatedly discussed for two days, mainly to conduct detailed discussions on tactics such as ambushes, intersperses, and long-distance attacks, and added a lot of space to the plan to study and guide these tactics, and finally brought in Tao Rong, Zhang Yafei, Gao Zongbao, and others to make a final confirmation of the plan and outline, and finalized it until everyone had no objections. Through the discussion in the past few days, Tao Rong and others all admired Song Zhewu's tactical literacy. Li Wentian even believes that Song Zhewu can be called a tactician, even if he is not a military strategist (because, after all, Song Zhewu has not commanded a more famous battle), he can be called a tactician.

A few days later, Yan Xishan's representative, Zhao Pilian, and his entourage, accompanied by Xiao Guodong, came to Laiyuan.

Song Zhewu was not in Laiyuan at this time, he had already run to the station of the Fuping Mountain Brigade 80 miles away. Song Zhewu knows very little about mountain warfare, not to mention mountain training, even mountain warfare He only has an impression in novels and movies, he is not here to guide work, he just came to see this Li Ruifang, who is actually responsible for the training of the mountain brigade, to see how he conducts mountain training.

Li Ruifang is very grateful for this exception to promote him from the battalion commander to the deputy brigade commander, although he has Tao Rong's recommendation, but after all, he is a general who has just joined the Fourth Route Army, Song Zhewu can trust him like this, and Tao Rong also hinted to him that as long as he does well, Song Zhewu will hand over the mountain brigade to him in the future. Therefore, Li Ruifang made great efforts to train the mountain brigade, and on the second day after the personnel were in place, he and Ye Changgui took the mountain brigade to Fuping.

The reason why I came to Fuping is because the mountainous terrain here is more complex than Laiyuan, which is convenient for training.

The training of the mountain brigade is very arduous, and their regular training subjects include mountain marching, armed climbing in the mountains, and how to use the terrain to cover and block attacks, and some training subjects are even short-sighted to the training of special brigades.

The armament of the mountain brigade is also very distinctive, they do not have mountain artillery, even the mortar is only 60mm, which is mainly to move quickly in complex areas, because they sometimes need to pass through areas where there are no roads at all. For this reason, even they were not equipped with heavy machine guns. In addition to their personal weapons, individual soldiers are also equipped with a dagger similar to that of special forces, which is mainly used for climbing.

After watching it for two days, Song Zhewu returned to Laiyuan with confidence, not only because he was very satisfied with the Li Ruifang recommended by Tao Rong, but also because Xiao Guodong had sent someone to urge him three times in a row. Zhao Pilian has been in Laiyuan for two days, and if he, the commander-in-chief, will not go back, he really can't say anything.

Actually, it is true that Song Zhewu is very busy these days, but he is not so busy that he can't get out of his body, the reason why he does this is that he wants to cool this henchman of Yan Xishan first, and kill his sharp spirit first. He wanted Yan Xishan to know that it was Yan Xishan and his Jin Suijun who needed him Song Zhewu, not him Song Zhewu.

sent Xiao Guodong to greet him, because Zhao Pilian had the status of deputy minister of the Ministry of the Interior after all, but when he arrived in Laiyuan, he had to act according to his arrangement.
