Chapter 512: Stupid Bird

Although the Yulin Army conducted a carpet search near the test site, however, the Yulin Army's search was not too serious, the area to be used for the airship test was too large, and this was originally a semi-public test to strengthen people's morale, and there were many ordinary people, officials, scholars, and their families who flocked to watch the airship. In Yunzhou, this kind of public test often sets aside an area for these people to gather for viewing and discussion, but Northern Liao has relatively little management experience in this area, and no one has made such a suggestion. Many people rush to several locations with good views to spread out their floor mats and put food and wine on them, as if they are on an outing. In this case, the two spies of the Dongping Intelligence Bureau, who were brightly dressed and carrying binoculars, were not conspicuous at all. The binoculars in their hands aroused a burst of curiosity from the officers of the Yulin Army who came to investigate. In Northern Liao, telescopes are a rare thing, except for the military, only a small number of powerful families, or the smuggling trade of the rich family has this thing. However, since these two young men had a binoculars in their hands, the officers of the Yulin Army did not dare to offend.

The test was originally scheduled to start after the last dynasty when the lord came to the test site, but because something happened during the previous dynasty today, there was a discordant discussion about the Western Route Army and Gao Sen Banner in the court, almost an hour later than usual. By the time the head of the country arrived at the test site, it was already noon. After a little preparation, the test begins.

In the chaos of the ground crew, a total of four airships were slowly lifted into the air using the airship mechanism on the Chunnan side, occupying the four corners of the test area. The appearance of these airships is still slightly different from the prototype on Chunnan's side. The airship pod on the Chunnan side is made of iron frame and wood, while the Beiliao side doesn't know what the considerations are, so it uses a rattan frame with a skin on the outside. It is said that it is skin, but at a glance, it should be something similar to leather armor, and the tanning process of Beiliao is indeed relatively mature, but in this way, the pod of the airship will have the problem of insufficient weight and poor stability. Chunnan's use of iron-framed wooden shells is not because they don't want to reduce weight, but because they really can't solve the problem of stability. On the Northern Liao side, I'm afraid it's still relatively immature in design, and I haven't encountered this kind of problem at all.

Then, looking out over the valley from the hillside, you can see a large number of soldiers and craftsmen pushing a huge airship out of the warehouse on one side. Then it is heated and inflated. As the airship's airbag swelled, the two spies couldn't help but "pout" in surprise.

Beiliao's self-developed airship is very interesting. The airbag of the airship is not the relatively conservative oval mushroom type when Yunzhou first developed the airship, nor is it a cigar type that pursues speed or a teardrop shape like the very mature snow owl, but a complex geometry that is not easy to describe, and the ridge lines are very clear. The front is a bit wider, while the rear has four rear wings. What is even more surprising is the pod below, which is also geometric, and blends in with the shape of the entire airship, which looks very harmonious. The airship is very large from head to tail, and the pod is a little small in comparison, but this airship is still a lot bigger than Chunnan's airship. It looks like the payload is quite impressive.

"Xiaoyu, it looks like they're doing a good job." The older spy muttered.

"Look there...... The power part of the airship, I really don't know what they think......" Xiao Yu's observation seemed to be more detailed. The power system of Beiliao's airship is so huge that it occupies a quarter of the space of the entire pod. Of course, this includes parts such as fuel tanks, but there is no classic design such as a nozzle. "It looks like it can fly a long way. Lao Xu, what they did was not bad. ”

"What's the use of flying far away...... Can such a pod stay human? Old Xu muttered. They are all very experienced people with airships, otherwise it would not be their turn to do this kind of investigation, the power and control of the airship, but the most critical part of the entire airship. It's not just about making the airship fly far and high, it's also about the comfort of the crew. Ye Tao's airship has always done a very good job in this regard from the first model to the present. The airship has always been easy to control and easy to maintain, and the crew can always work in a comfortable situation. But looking at this kind of airship in Northern Liao, it seems to be different. The power plant that occupies such a large part of the pod generates enough heat to drive the crew crazy, and it is not convenient to carry things like fire oil bombs, which is too unsafe. If you want to talk about the advantages, it is very obvious that this kind of airship is obviously very convenient to produce, and the airbag with a geometric shape is much more convenient than the teardrop-shaped airbag in Yunzhou. As long as the seam is qualified, it is fine.

The airship slowly lifted into the air, and the attitude was very well controlled, which was a very classic attitude of the tail being cocked first, and then slowly rising in a straight line. The ground crews pulling the ropes on the ground didn't seem to be having a hard time controlling them. Lao Xu and Xiao Yu could see that there were now five people in the airship's pod, which seemed to be a standard flight team outfit. The other party communicates with the ground by relying on the flag. On the one hand, it is daytime, and the technology of communication light box is one of Dongping's secrets. The highly concentrated but incomparably light metal cover inside can only be produced by a small workshop in the Yunzhou branch of Ye's Workshop, and there is no other semicolon. Only electric lights can produce light of sufficient intensity to make contact during the day. The entire technical system related to electricity, although Beiliao wants to learn, I am afraid that it is also powerless.

The airship rose to a height of about 150 meters, and after performing some horizontal maneuvers, it climbed again, and then made different maneuvers at several heights of 250 meters, 400 meters, and 500 meters. And looking closely at these air maneuvers, Xiao Yu couldn't help but pout with disdain. "Old Xu, shouldn't they be able to carry out a sharp lifting action?"

Lao Xu smiled, leaned in front of the telescope and didn't take his eyes off, not impressed. Even in Yunzhou, the sharp lifting action is quite difficult. This is due to the mechanism by which the air is heated. In the beginning, the flame nozzle used was single-mouthed, and the flame was relatively high, and once the sudden rise and fall was carried out, the flame was likely to burn to the edge of the air bag, causing a fire. Ye Tao also did not change the single-hole nozzle to a multi-hole nozzle until after the third batch of airships, the flame height was very low, and there were special protective devices outside. In addition, the porous jet can also determine which vents to ignite on a case-by-case basis, making the airship more flexible. However, this kind of technology is only used in the airship of the Dongping military, even if the communication bureau and the two major logistics companies have not used such a high-end technology, of course, those airships used by the post transmission do not need to rise and fall sharply, as long as they can fly at a relatively safe angle.

"Let's go, it's enough to see here." Lao Xu said to Xiao Yu. They hurried away. Insiders look at the doorway, and they have no reason to keep it. They will report the results of their observations truthfully, and the rest of the information, they don't have to risk knowing the specific data, that's not their job. After all, there is still Kong Xinhua at the bottom.

Unlike those spies from the Intelligence Bureau, Kong Xinhua could not know what the performance of the airship might be like through ordinary observation. Although he has also flown in airships and even snow owls, he is not an expert in professional engineering after all. His mind rarely pondered this aspect, but when he saw the officials of the Ministry of Industry and Situ Lian describing the performance and manufacturing of the entire airship to the lord of the country and other important ministers of the DPRK and China, he still had some confidence in his heart. This kind of airship is stronger than Chunnan's airship, whether it is flight altitude, speed or load capacity. However, compared with Chunnan's airship, the seaworthiness of this airship is worse, and the cost is even more expensive.

"Mr. Kong, can you think of a way to see how many things are on this list?" What Situ Lian handed over to Kong Xinhua was a very exaggerated list, covering a series of things from metal materials, processing tools, precision knives and cutting tools, craftsmen and training tutorials, etc., Northern Liao was too far from several other countries in terms of craftsmanship, and airships were really difficult for them.

As long as Kong Xinhua asked Ye Tao for it, he could get these things, but he was a little hesitant. He asked, "Lord Situ, do you mean that except for the tanning process, the entire manufacturing has to rely on external forces to find people?" This cost ......"

Situ Lian sighed and said, "Your Majesty has made a decision to build at least thirty airships in a year, but with the current strength of the Ministry of Industry, it is already the limit to be able to build more than one airship a month." Such a task cannot be accomplished, and moreover, such an expense cannot be afforded. Although the performance is better than Chunnan's airship, the cost is almost three times higher. Moreover, this thing is not something that someone can use when they go up. How to use it and how to cooperate with the battle is really a long way to go. However, the latter things are not out of my control. ”

Kong Xinhua hesitated, but still asked his entourage to bring up a package. He said: "Lord Situ, this was originally going to congratulate you on the success of this airship test flight. You see, maybe it's inspiring. I took this list, but I can't guarantee what it will do. materials and tools, and perhaps a way to think of it, as for the craftsmen...... The villain really doesn't have that way. But I'll think about it. If this airship is so expensive and you don't know how to use it, it's better not to ...... One year, Lord Situ, villain is brave, can Ye Tao really give me a year in Beiliao? ”

Situ Lian sighed and opened the package. There is actually a thick book of "Snow Owl Airship Operation Guide", which is the kind of thing that is placed in the engine room for pilots to inquire about how to operate under various circumstances, full of pictures and texts, and there are detailed diagrams for many parts, and the accuracy is comparable to that of drawings. Situ Lian's eyes lit up, but soon they dimmed, and he said, "Snow owl...... It's too strong to compare......"
