Chapter 866 Remarks

The aviation industry of the Qimarang secret base is a complete industrial chain built from scratch, following the principle of "higher, faster, stronger", from project establishment, research and development, experimentation to production, and finally spreading its wings to the blue sky. Completed inside the secret base.

Ninety-nine percent of the technicians here are of Chinese descent. Only the Aero Engine Design Institute has more than 20 German engineers. These German engineers are the backbone of the Aeroengine Institute, designing and producing world-leading propeller-type high-horsepower piston engines. .

   As the saying goes, the train runs fast or not depends on the headband.

  The same is true in the aviation field. Excellent aerodynamic design coupled with powerful engines can create an excellent aircraft of the world's advanced level.

  In the tall and spacious hangar

   In front of Li Fushou is a streamlined monoplane and a much larger biplane, which represent the base's latest scientific research achievements.

   The technical director of the base, Fan Wenhao, who is in charge of the explanation, is a 28-year-old engineer with a pair of gold-wire glasses on his face, and he looks polite. Most of the technicians here are also young people who are obsessed with aviation, with ideas, energy and vitality.

   "Dear Your Majesty, in order to obtain higher speed and flexibility, this monoplane fighter is designed with a spindle-shaped streamline body, so we call it "spindle".

  You look here…

In the front part of the aircraft spindle and the leading edge of the wing, we have used a thin aluminum alloy plate to cover it. This design is to obtain the best hydrodynamic performance, coupled with the rationality of the overall aerodynamic structure, so "spindle" "A monoplane fighter can achieve a high speed of 248 kilometers per hour, which can be said to be the fastest aircraft in the world today.

  The aircraft uses a "Thor" radial piston engine, which can provide 185 horsepower, a practical ceiling of 5,700 meters, a length of 7.35 meters, a wingspan of 9.65 meters, a height of 2.55 meters, and a battery life of 1.5 hours.

  The aircraft has an empty weight of 442 kg and a maximum take-off weight of 690 kg. It belongs to a single-seat, single-engine, monoplane fighter.

   The "Spindle" monoplane fighter can be equipped with an 02-type aviation machine gun, placed in front of the aircraft pilot, and the pilot can operate the machine gun to attack the enemy.

   Considering that fighter jets need maneuverable and flexible hovering operations, we did not aim at high speed at the beginning of the design, but balanced between maneuverability and high speed.

  In order to increase the flexibility and maneuverability of the fighter, we increased the area of ​​the tail rudder. In order to enhance the strength of the body, the wooden frame was abandoned, and the welded steel frame was used instead.

  In order to obtain better aerodynamic performance, aluminum alloy sheets were covered on the spindle body and the leading edge of the wing, which proved to be a very successful attempt.

  The speed of mainstream aircraft in the world today is generally between 140 kilometers and 180 kilometers. The fastest speed is just over 200 kilometers, which is a long way from us.

Objectively speaking

   The performance of the "Spindle" monoplane fighter is extremely superior. In the next ten years, European and American countries will not be able to manufacture the same type of advanced aircraft.

The only drawback of    is the high cost. Such a monoplane fighter costs as much as tens of thousands of dollars. Even if it is mass-produced, the cost cannot be reduced much. This is where we are troubled. "

  Li Fushou listened and nodded without saying anything.

   In his eyes, the plane is very simple. It is a body made of steel pipes and wood. Except for a few parts covered with aluminum alloy sheets, the rest are covered with rubber and cloth, which looks like a shoddy product made in a manual workshop.

   But this is the reality of today's aviation industry. Everything has just started. Aviation theory and airframe materials are all being explored. As for aviation equipment, it is completely zero and nothing.

   The **** and rudder are controlled by wire, the engine is started by hand, and the landing system is watched by eyes. The wheel is a tripod welded with steel pipe, and a solid rubber wheel is put on it. I am afraid that the wheel bearing has a little technological content.

   The most valuable thing on this plane is the "Thor" radial piston engine, produced by Qimarang Aviation Engine Factory. A single unit is worth 7,600 Jinyang, which is still a loss of money.

Because the "Thor" aero-engine factory has so many high-value equipment and more than 140 highly educated employees, the annual output is only a few dozen engines, and the piston engine models are different. It is completely for the experimental base, not for large-scale. Mass production is purely at a loss.

80% of the cost of this monoplane fighter is the engine, and the rest of the steel pipe welded body, wood frame and skin plus iron wire are not worth much. It is estimated that the material cost accounts for 30%, the labor accounts for 70%, and the more expensive aluminum is aluminum. Alloy sheet.

  This… is already the top aviation level in the world today.

  Most of today's airplanes are made of wood, and then covered with tape. It is already a lot of money to use steel pipes to make the body frame, not to mention aluminum alloy sheets, which are considered cutting-edge body materials.

Civil aircraft generally use cheap engines, most of which are between 30 and 50 horsepower. The expensive ones are 200 to 300 jinyangs, and the cheap ones are 100 jinyangs. Therefore, an aircraft is very cheap, even cheaper than a cheap Volkswagen brand car. many.

   It is precisely because private planes are cheap that they can be popularized in the vast pastures of Australia and overseas states, and are loved by many people and become an emerging folk sport.

   In this day and age

   There is no "Air Control Law", and there is no need for an aircraft driver's license, let alone an airstrip, as long as you can take off and land on a dirt road.

   This kind of environment is extremely friendly to flying enthusiasts who like to fly in the blue sky. There is almost no threshold. Just spend money to buy a plane or build one yourself and fly in the sky.

The Empire deliberately allowed the rise of flying clubs in various places, which made all kinds of local flying clubs bloom like a spring breeze, and spread all over the major cities and remote towns in Australia. This trend has even spread to overseas states. And Borneo became the new hipster sport.

  Because the cost is too low, many wood workshops have been converted into aircraft factories. This primary version of the aircraft factory is only responsible for building the frame of the aircraft, and then buys an engine and installs it on the nose, and it's done.

   In such a crowded and mixed environment, it is inevitable that many aviation accidents will occur. Some planes fall apart when they reach the sky, and some fall down before they fly far, resulting in tragic accidents where the plane crashes and kills people.

  Relevant parties in the empire are promulgating relevant bills to control the current chaos in aircraft manufacturing plants, clarify responsibilities, and improve the entry threshold. The most important one is that every establishment of an aircraft manufacturing plant must pay 5,000 Jinyang Aviation Accident Insurance Fund.

   This aviation accident deposit is used to protect the rights and interests of customers and prevent unqualified aircraft from flying into the sky. If an aviation accident occurs due to unqualified quality, the aviation accident insurance premium paid by the manufacturer can be paid first, and then the relevant manufacturers will be held responsible.

   This alone can shut out more than 90% of the aircraft manufacturers.

   Circling around the latest "Spindle" monoplane fighter, Li Fushou asked a few related matters out of politeness, and there was nothing left to say.

Fan Wenhao is really not bragging, this "spindle" monoplane fighter has the strength to hang all European and American fighter jets in the next 10 years. With its high speed of 248 kilometers per hour and high mobility, it has already made European and American countries difficult to beat. and.

  If I remember correctly

  The bi-wing Camel F1 fighter developed by the United Kingdom at the end of World War I has a maximum speed of about 185 kilometers. Germany's "Fokker" monoplane fighter, which made a big splash in World War I, has a maximum speed of 140 kilometers per hour, which is a bit worse than the boss!

Why is a monoplane slower than a biplane?

   The main culprit is that the engine power used by the "Fokker" monoplane fighter is too small, only about 110 horsepower, and the flight speed is naturally not fast.

Li Fushou climbed up the ladder and sat in the cockpit of the "spindle" monoplane fighter. He looked at the simple cockpit welded by steel pipes and the frame reinforced with wooden strips. A few wires under his feet controlled the pulley, which was to control the flight rudder. I really don't know what to say?

   "There should be a clock in this cockpit, at least to know what time?"

"This seat is not comfortable, it's too hard, you know that pilots go to the sky to fight, and try to create a comfortable environment for them as much as possible. A layer of latex on the seat won't add much weight, But it's friendly to pilots."

   "This aviation seat can be made into a tube shape, wrap the sides of the body, and then use a strap to fasten the body to the seat, so that the aircraft will not sway left and right or leave the cockpit when maneuvering."

  Li Fushou looked at the high machine gun on the top of his head, and put it on an iron stand at a height of more than one meter above his head, just to prevent the machine gun bullet from breaking the propeller.

   So he pointed to the machine gun mount on his head and said; "This machine gun is set so high, how does the pilot aim?"

"Dear Your Majesty, we have always been troubled by this. If the weapon is set too low, the propeller will be shattered, resulting in the accident of crashing the aircraft. If the setting is too high, the aiming will be inaccurate, so this is an unsolvable problem." Fan Wenhao stood on the edge of the ladder and explained with an embarrassed expression.

  Li Fushou couldn't help but slap his mouth, this is a problem of misunderstanding.

   He pointed to the gap in front of the propeller and said; "The propeller gap is so large that a mechanical linkage can be set up. When the propeller runs to the position of the gap of the machine gun and fires the bullet, there will be no mutual interference. Is this difficult to solve?"

What Li Fushou was talking about was the principle of "shooting coordinator" first applied by Fokker fighter jets in 1915. With this unique skill, the Germans shot down more than 1,400 British aircraft, making British pilots on the Western Front less than 6 weeks old. , really terrified.

  The United Kingdom once offered a price of 10 million US dollars for this, and kindly invited the Dutchman Fokker to play in the UK. Unfortunately, this letter was suppressed by the Germans. Fokker did not know until the end of the First World War.

   Many times the technical problem is just a window paper, and it is easy to solve it when you open it.

Li Fushou's words made Fan Wenhao stunned for a while, and after thinking carefully for a moment, he suddenly became enlightened and said excitedly; "Dear Your Majesty, we are too stupid to think of such a simple problem. The method you mentioned is indeed very useful. It's really good to be simple and reliable. Your Majesty is really pedantic, and you can wake up a dreamer with one word!"

"Hehe... You are thinking about the problem from the designer's point of view, and I am thinking about the problem from the point of view of the pilot, so the point of view is different, and the perspective of looking at the problem is also different." Li Fushou did not hesitate to give more pointers to let Aircraft designers take fewer detours.

  Although he is not a flight expert, he has a vision beyond the times after all, and he is still qualified to guide these engineers who change careers halfway.

  Li Fushou pointed to the open cockpit and said, "You aircraft designers need to learn to fly, and experience it for yourself as pilots. Is the designed aircraft good enough?

  Is there anything worth improving?

   Does the higher cockpit have a better view?

   At a maximum speed of 248 kilometers per hour, the open cockpit may not be able to speak, so is it possible to design a closed cockpit?

   Then in the closed cockpit, you can carry a portable water bottle, pistol, and flashlight. In the future, after the miniaturization of radio, will it be possible to carry radio communication?

   These are all questions that can be considered. For example, does the machine gun have to be placed on the right side of the pilot? Can it be placed under the feet?

   In this way, the pilot's field of vision is not delayed, and it can also be located on the center line of the shooting, which has no effect on the shooting accuracy. Instead, the pilot does not need to be affected by the thrown bullet casings and concentrates on driving the aircraft to fight.

  If two mirrors are installed in the cockpit, then the pilot can see the situation behind the side without turning around. It doesn’t cost much, isn’t it more beneficial?

   generalize

   If a window is set at the bottom of the cockpit or on the side, will the pilot’s observation be more comprehensive?

   Such issues should be considered as an aircraft designer.

  My request is not to consider cost, but to try to design an aircraft with high performance, high reliability, and a highly friendly driving environment, which must be remembered.

  After the initial success, we must start designing aircraft with faster speed, heavier load capacity, and stronger combat effectiveness. We must not rest on our laurels and be complacent on the merits of the past. Such thinking is unacceptable..."

Li Fushou made a big talk, and the entourage standing under the plane took a small notebook and quickly recorded it. Today, His Majesty's words opened a new door for all the technical personnel present, allowing them to see a clear development. direction, a better future.

   They really didn't think that the plane could be designed like this, but if you think about it carefully, it's really a gem.

  Every word that His Majesty said was a good word, thought-provoking.

  The outstanding scientific and technological achievements he is proud of have so many shortcomings, they are simply a broken sieve leaking everywhere, Fan Wenhao suddenly felt very ashamed, after all, he was superficial.

   The world is huge, the world is vast, and talented people and talents are like countless crucian carp crossing the river. What is there to be proud of?

   We all know that Grape-kun has never saved manuscripts. In the past few days, there have been more updates. It really started from six o'clock in the morning and continued to write until eleven o'clock in the evening. The pen can't do it slowly. Moreover, I often write and play, play with flowers and tease the cat and then feed the koi. I can't concentrate, and I can't write much in a busy day.

   For the sake of Grape-kun's hard work, everyone will give monthly tickets and recommended tickets! Thank you very much.
