The weapon tycoon who traveled to Daqin

Shang Wen was lying on the cushion, and he couldn't sleep. In all kinds of posture, he couldn't sleep.

It is a very uncomfortable thing to sleep. Shang Wen gets up to drink saliva. I want to continue to sleep. But I still count it. I have to stay up all night. In this era, there is no coffee.

But drink water. Tea is a bit bitter.

Shang Wen sat down and sorted out his thoughts quietly. First of all, it was the place to sit. In this era, everyone is still sitting, and even the chair and stools have not appeared. Sitting, it is actually kneeling.

It is a big test. Shang Wen suffers from discussing the government's politics every time. Especially when those huge war plans, Shang Wen stood up and talked, because he kneeling.

Kneeling down. I don't know if there is a disease like arthritis.

Thinking of this, Shang Wen discovered that his previous invention was concentrated in heavy industry, or he was biased towards very technical things, and he had serious neglect of some lives around him. For example, these furniture around

There is no invention. If it wasn't for the accidental proposal today. Shang Wen has almost forgotten that life can become better.

Too much concern, often ignore many things.

Thinking of this. Shang Wen's interests came suddenly. Furniture, sofa, chairs, stools. Modern style coffee tables, desks. If you can add the boss chair, it is best to add a stack of paper and start drawing the figure.

Now there have been more modern wood machining machines. These things are not difficult to process. Sofa. There are no sponges. You can only make old spring sofas.

Back chairs equipped with spring or thick foam plastics have armrests on both sides. This is the basic summary of the sofa. With sofa, it can be used in other places.

. Since there are four rounds of carriages. The loading capacity is not only doubled, but more importantly, the manned and loading. It has a lot of improvement. If you add the sofa, it may be more comfortable to take people.

Transparent glass. It has the style of modern cars.

In addition, there are many things, chairs, boss chairs, and desks. These need to be processed.

Shang Wen spent an hour of time to draw drawings, and then took a lot of drawings to go to the airship workshop. There are the most concentrated places for carpenters.

The drawings are given to those carpenter, and the rest are their own affairs. And Shang Wen still has a lot of time.

Shang Wen will turn attention to other aspects. Since in the airship workshop, we must design the airship -related things.

The airship cannot measure the height, which has always been an important factor that plagues flight. Especially speed and height. The speed requires an air-speed tube. The air-speed pipe is also called the pipe of the pipe, the total pressure tube, the total-static pressure pipe. It is the total pressure of the airflow.

(Also known as full pressure) and static pressure, and transmit the measured pressure data to the atmospheric data computer, the device of the flight instrument. This kind of aviation device is mainly used to measure the flight speed, and at the same time, it also has multiple functions.

The current technology cannot develop such advanced aerial pipes.

It consists of two concentric circular tubes, the inner circular tube is the total pressure pipe, and the coat tube is a static pressure pipe. The principle of the speed of the air -speed tube measured the speed of the aircraft is the Cessna air -speed pipe

When the aircraft flight forward, the airflow rushed into the air -speed tube. The sensor at the end of the tube will feel the impact force of the airflow, that is, the faster pressure of the aircraft, the greater the dynamic pressure.

When the pressure is static and dynamic pressure, you can know how fast the air rushing in, that is, how fast the plane flies. Comparing two kinds of pressure tools are a very thin metal piece made of upper and lower pieces.

The hollow round box with ripples on the surface is called a membrane box. This box is sealed, but there is a tube connected to the airspace.

The box will bulge. Use a device consisting of small lever and gears to measure the deformation of the membrane box and display it with a pointer. This is the simplest aircraft airspace.

The speed measured by the air -speed tube is not the speed of the aircraft really relative to the ground, but the speed of the atmosphere, so it is called an air speed. If there is wind, the aircraft is relative to the ground speed (called ground speed).

(Flying on the wind) or minus the wind speed (anti -air flight). In addition, the principle of the speed of the air -speed tube speed is used to the pressure, and the dynamic pressure is related to the atmospheric density.

The film box deformation in the table is that the same airspace is the same, and the value ratio of the high altitude ratio is generally called "surface speed" at low air school. There are two pointers on the modern airspace.

A relatively wide. Wide pointer indicates "surface speed", and the fine one indicates that the airspace speed when various corrections are equivalent to the atmospheric pressure on the ground, called "real speed".

In order to prevent the front -end small holes from the front end of the airspace tube blocked during flight, the airspace tube on the aircraft has an electric heating device.

The membrane box becomes the key. In addition, the meter that measures and indicates that the horizontal base of the horizontal base of the aircraft is called the height table.

The height table installed on the aircraft's cockpit instrument panel usually has a air pressure height table and a radio altitude table. The air pressure type height table is actually an air pressure meter. It measures the height of the aircraft's height atmosphere and indirectly measures the flight height.

The radio height table is actually a ranging radar with ground (water surface) as the detection target. The height it indicates is the real height.

The super -modern height table cannot be created. But another kind of thing is OK. That is the air pressure meter.

It is made according to the principle of Tori's piercing experimental principles to measure the instrument that measures atmospheric pressure. The types of gas pressure meters include mercury and air pressure meter and no hydraulic pressureometer.

When the air pressure is reduced, there will be wind and rainy weather. The measurement height will be reduced. Every 12 meters up, the mercury column will be reduced by about 1 mm. Therefore, the height of the measurement of the mountain and the height of the aircraft when flying in the air.

It can also predict the changes in the weather. When the air pressure is high, the weather is fine; when the air pressure is reduced, there will be wind and rain.

Use the Tori's disassembly tube to determine a device of the atmospheric pressure. The mercury slot at the bottom of the glass tube is replaced by a leather sac, and an ivory needle that can be adjusted can instruct the mercury surface.

"Add a metal sheath outside the glass tube, and the tube is engraved with a scale of the height of the silver column. Another ivory needle on the roof of the mercury slot.

The leather bag is used as the bottom of the mercury groove. When used, the spiral under the leather bag makes the silver surface in the groove exactly contact with the ivory tip (that is, at zero point with the scalar ruler at a horizontal line), and then read the mercury from the tube scale ruler.

The height of the pillar. This height is the size of the local atmosphere at that time. In addition, there is an observation station for the ivory needle that does not need to adjust the ivory needle, which can measure the air pressure meter used for low pressure mountains, as well as the shaking of the ship is not sensitive

Blood pressure meter.

The height of the mercury column that is supported by the atmospheric pressure is different. According to the P = P (mercury density) HG, the calculated pressure is equal to the atmospheric pressure. Of course, the calculation of the air pressure meter is marked on the gas pressure meter.

The scale of the air pressure can be known!

However, the problem eventually points to a problem. The processing of glass tube. And a large amount of raw materials.

A very complicated logical reasoning. The gas pressure meter requires glass. What should I do if the glass requires sodium carbonate. What should I do?
