Chapter 512 Stupid Bird

Although the Yulin Army conducted a carpet-style search of the location where the test was conducted, it still allowed several spies from the Dongping Intelligence Bureau to hide. However, the Yulin Army's search was not too serious. The area for the airship test was too large. Moreover, it was a semi-public test to boost people's livelihood and morale. There were quite a few people, officials, scholars and their families who came to watch the airship. In Yunzhou, such public tests often set aside an area for these people to gather together to watch, which was convenient for discussion. However, Bei Liao had relatively little management experience in this area, and no one made such suggestions.

Everyone took the lead to several places with good vision to spread the floor mats, put food and wine on, as if they were on an outing. In this case, the two spies from the Dongping Intelligence Bureau who were dressed in bright clothes and carrying telescopes were not conspicuous at all. The telescopes in their hands attracted the curiosity of the Yulin Army officers who came to investigate. In Beiliao, telescopes are rare things. Except for the army, only a few powerful families, or wealthy families who do smuggling trade, have this thing. However, since these two young people have a binocular high-precision telescope, the Yulin Army officers are even more afraid to offend them.

The test was originally scheduled to start after the imperial court, and the king came to the test site, but because something happened during the imperial court today, the disharmonious discussion broke out about the Western Route Army and Gaosen Banner, one hour later than usual. When the king arrived at the test site, it was already noon. After a little preparation, the test began.

In the busy turmoil of the ground crew, the first thing is to use the airship mechanism in Chunnan to slowly take off, occupying four corners of the test area. The shapes of these airships are slightly different from the prototypes in Chunnan. The airship pods in Chunnan are made of iron frames, and the Beiliao are not sure what they are doing. They use rattan frames and skins on the outside. They are said to be skins, but at a glance, they should be something like leather armor. The leather making process of Beiliao is indeed relatively mature, but in this way, the airship pods will have problems of insufficient weight and poor stability. The use of iron frames and wooden shells in Chunnan is not because they do not want to reduce the weight, but because they really cannot solve the problem of stability. In the Beiliao, they are probably still immature in design and have never encountered such problems at all.

Then, looking at the test site of the Ministry of Works in the valley from the hillside, you can see a large number of soldiers and craftsmen pushing out a huge airship from the warehouse on one side. Then heat and inflate it. As the airship's airbags swelled up, the two spies couldn't help but exclaimed in surprise.

The airship developed by Beiliao is quite interesting. The airship's airbags are not the oval mushroom type that was conservative when Yunzhou first developed the airship, nor the cigar type that pursued speed or the water droplet shape used by the already mature snow owl. It is a complex geometric body that is not easy to describe, with the ridges of the ridges very clear. The front is wider, and the tail has four tail wings. What is even more surprising is the pod below, which is also geometric, blending with the appearance of the entire airship, and it looks very harmonious. The airship is very large from beginning to end, and in comparison, the pod is a little smaller, but this airship is still much larger than the airship in Chunnan. It looks quite considerable in load capacity.

"Xiaoyu, it seems they are doing a good job." The older spy muttered.

"Look there... the power part of the airship, I really don't know what they thought..." Xiaoyu's observation seemed to be more detailed. The power system of the Beiliao airship was so huge, occupying a quarter of the space of the entire pod. Of course, it also includes the fuel tank, but there is no classic design like the jet port. "It seems that this thing can fly far. Lao Xu, they are doing a good job."

"What's the use of flying far away... Can such a pod be staying in a pod?" Old Xu murmured. They are all people who are very experienced in airships, otherwise they would not be their turn to do such investigations. The power and control devices of the airship are the most critical part of the entire airship. Not only do you want to fly far and high, but you also have to consider the comfort of the passengers. Ye Tao's airship has always done a very good job in this regard from the first model to now. The airship has always been easy to control and easy to maintain. The passengers have been employed.

It can always work in a relatively comfortable situation. But looking at the airships of Beiliao, it seems different. The power device that occupies such a large pod has enough heat to drive the crew crazy, and it is not convenient to carry things like sulphurs, which is too unsafe. To talk about the advantages, it is very obvious that this airship is obviously very convenient to produce. The geometric airbags are much more convenient than creating water droplet-shaped airbags in Yunzhou. As long as the joints are qualified, it is enough.

The airship slowly took off, and its posture was very well controlled. It was a very classic posture of lifting its tail first and then slowly taking off in a straight line. The ground crew members who pulled the ropes on the ground didn't seem to have to control it. Lao Xu and Xiaoyu could see that there were five people in the pole of the airship, which seemed to be a standard flight team. The other party contacted the ground by flag words. On the one hand, it was daytime now, and in addition, the communication light box technology is one of the secrets of Dongping. The highly concentrated but extremely light metal cover inside is currently only a small workshop in the Yunzhou branch of Ye's Workshop can produce, and there is no semicolon. Only electric lights can produce lights of sufficient intensity for daytime contact. Although Bei Liao wants to learn the entire technical system related to electricity, he is probably powerless.

The airship rose to a height of about 150 meters, and after some horizontal movements, it climbed again, and then made different movements at a height of 250 meters, 400 meters and 500 meters in turn. Looking at these air maneuvers carefully, Xiao Yu couldn't help but curl his lips with contempt. "Old Xu, why can't they do a sharp lifting and lowering action?"

Old Xu smiled, and did not take his eyes away from the telescope. He didn't care. The rapid lifting and lowering movement was quite difficult even in Yunzhou. This was determined by the mechanism of heating air. At the beginning, the flame nozzle used was single-ported, and the flame was relatively high. Once the rapid lifting and lowering was carried out, the flame was likely to burn to the edge of the airbag and cause a fire. Ye Tao changed the single-ported nozzle to a porous nozzle until after the third batch of airships. The flame height was very low, and there were special protective devices outside. Moreover, the porous jet could also determine which nozzles to ignite according to the specific situation, so that the airships of the Dongping military were more flexible. However, this technology was only used in the airships of the Dongping Military. Even the Communication Bureau and the two major logistics companies did not use such high-end technology. Of course, those airships used by the Post did not need to slash lifting and lowering, as long as they could fly at a safer angle.

"Let's go, it's enough to see this here." Old Xu said to Xiaoyu. They hurriedly left. Experts looked at the tricks, but they had no reason to keep them. They would report the results of their observations truthfully, and they didn't have to take risks to understand the specific data for other information. That was not their job. After all, Kong Xinhua was still there.

Unlike those spies from the Intelligence Bureau, Kong Xinhua could not know what the performance of the airship might be like through general observation. Although he had also taken airships, or even Xue Xiao, he was not a professional engineering and technology expert. His mind rarely thought about this. However, when he saw the officials of the Ministry of Works and Situ Lian describing the performance and manufacturing conditions of the entire airship to the king and other important officials in the court, he was still a little relieved. This airship is stronger than the airship in Chunnan, whether it is flight altitude, speed or load capacity. However, compared with Chunnan's airship, this airship is less airworthy and more expensive in terms of cost.

"Mr. Kong, can you think of a solution to see how much there is on this list?" Situ Lian handed Kong Xinhua a very exaggerated list, covering a series of things from metal materials, processing tools, precision blade tools, craftsmen and training tutorials, etc. Beiliao is too different from several other countries in terms of craftsmanship, and airships are really difficult for them.

Kong Xinhua asked Ye Tao for all these things, but he was a little hesitant. He asked: "Mr. Situ, what do you mean is that except for the process of making leather, do you have to rely on external forces to find people in the entire manufacturing process? This kind of cost..."

Situ Lian sighed and said, "Your Majesty has made a resolution to build at least thirty airships in a year. However, with the current strength of the Ministry of Works, it is already the limit to be able to build more than one in a month. You can definitely not complete such a task, and you cannot afford such a cost. Although the performance is stronger than Chunnan's airships, the cost is almost three times higher. Moreover, this thing cannot be used by someone. How to use it and how to cooperate with combat is really a long way to go. However, the following things are not something I can control."

Kong Xinhua was a little hesitant, but he still asked his followers to take a package. He said, "Mr. Situ, I was going to congratulate you on the successful test flight of the airship. You see, maybe it can be inspiring. I took this list, but it is really impossible to guarantee what it can be. Materials and tools, maybe I can still think of ways. As for the craftsman... the villain really has no way to go. But I will think of another way. If this airship is so expensive and I don't know how to use it, it's better not to... One year, Lord. Situ, the villain is brave. Can Ye Tao really give me a year in Beiliao?"
