Comrade, Your Ingredients Are Too Complicated

"Border Aircraft Manufacturing Factory: If we want to establish an independent aviation industry, then we must learn how to assemble aircraft and how to maintain existing aircraft.

Unlock time: 48 days

Effect: Obtain some information on AVIC's westward flight in 1958 (excluding jet aircraft), and obtain five researcher-level senior engineers.

Enable the manufacturer: AVIC XAC, the effect is (the aircraft production speed of the military factory in the system: +15%, the reliability of heavy fighter aircraft +20%, the reliability of tactical bomber bombers +20%)

Special note: All manufacturers can be selected superimposed. For example, you can choose Sino-German Technical Mission and Morozov Design Bureau as tank manufacturers at the same time. "

After seeing the two words "Xifei", Huang He immediately felt that trainer aircraft were no longer a problem. They were a big company that had developed and produced Feibao and H-6.

Even if it is just information from the propeller era, it will definitely benefit researchers of the current era.

The five aircraft design professionals are even more powerful. Their arrival can at least increase the research and development speed by half.

You must know that researcher-level senior engineers are one of the highest levels of engineer qualifications in later generations. Even a large company of XAC's level only has twenty-one.

If Erke can digest all these gains and cooperate with the factory unlocked in the next decision, it is estimated that the border area can develop and produce Chujiao-5 and Chujiao-6 in 1941.

However, if it is really built, in this era, it would be more suitable to be a high-end training aircraft.

After all, both of them are products of more than ten years later, and the Ugly Kingdom is still using the J-3 Cub to educate pilots.

Directly using a monoplane that is far beyond the current era as a primary trainer aircraft is somewhat thoughtless.

In Huanghe's plan, the future primary trainer aircraft of the Border Aviation School will definitely be a bi-wing light aircraft with a simple structure, easy to fly, and low price.

Then after being baptized by the castrated version of the fighter fighter and the Chujiao-5, the warrior can basically officially enter the combat sequence of the Kongyi Division.

The reason why I chose Chujiao-5 is not the well-received Chujiao-6.

That's because the latter considered training jet fighter pilots during the design stage. The landing gear adopted a front three-point design, which was very different from the mainstream rear three-point design during World War II.

All aircraft on the battlefield today are powered by piston propellers.

For aircraft with rear tricycle landing gear, tilting the nose up can leave space for the large-diameter propeller, and the compact tailwheel can also greatly reduce the structural weight.

This design fully complies with the industrial concept that the simpler, the more reliable and the safer it is.

In the busy work, the time came to December 31st.

Today is the last day of 1940, which means we are getting closer to the big news in the south.

Although the soldiers are not proficient enough to fly the C47 transport aircraft, the current situation must overcome difficulties and set out to transport aid supplies.

After arranging the work of the first section, Wang Dexing and Huang He drove from the bureau to the border airport.

When we were still ten minutes away from our destination, the young guard in the driver's seat suddenly pointed excitedly at the sky, without even looking at the road conditions for a while.

"Director! Look! It's our plane! It's not the Spitfire! It's the Fighter!"

No young person can refuse the temptation of soaring in the blue sky. As a guard of the Yellow River, Wang Dexing has the opportunity to have close contact with every aircraft in the border airport.

Although his literacy level was not high enough to pass the aviation school entrance test, he still memorized the name of each aircraft model.

After hearing the guards' cheers, Huang He stuck his head out of the cab.

The biplane fighter in the sky was doing some basic flight maneuvers. It looked like students from the aviation school were training.

"Drive a little faster. If we get to the airport now, we will most likely have a chance to see the landing process."

"Okay! Sit tight!"

After arriving at the airport, Huang He told Wang Dexing to park in the parking lot first, while he went straight to the runway. There were many students and instructors watching the rise and fall of the fighter jets. It took him a while to find Principal Chang among the crowd.

"Our academy is making rapid progress. Have you started practicing flying skills in just over a month? How is the situation recently? Have there been any accidents?"

Principal Chang was originally staring intently at the Fighter fighter jet that was about to land. When he heard someone speaking next to him, he subconsciously replied:

"Accidents are bound to happen. We have been working hard these days to avoid casualties."

"It is currently the third day of flight training, and one aircraft already needs major repairs. Yesterday, a student operated improperly and broke the propeller and engine when landing."

"Although the person is fine, I feel bad that the plane is broken down! It will definitely not be easy for Director Huang to get so many planes back. It will be troublesome if we can't replenish them."

The accident that Principal Chang mentioned happened yesterday when the students were practicing ground sliding.

Many people think that gliding is not difficult at all, as long as the engine is turned up and the gliding is done.

This view is a very common mistake. The ground taxiing of a rear three-point aircraft is like calculating the target distance for artillery. It is an absolute basic skill.

This is mainly because the main landing gear of the aircraft is located in front of the center of gravity. Once a yaw moment is generated due to lateral disturbance during taxiing, the ground friction will exert a force in the same direction on the main landing gear, further causing the yaw to increase.

Once a student becomes too nervous and the rudder correction amount is not accurate, it is easy to turn at a large angle.

Yesterday, a fighter jet was taxiing too fast, causing its tires to come off and even the landing gear to break.

When he said this, Principal Chang suddenly realized that the person next to him was Huang He. He hurriedly said hello, and then took the other person's arm to the position with the best view to watch the landing.

An aircraft will be divided into two types according to whether the landing gear is retractable, namely fixed landing gear and retractable landing gear. According to the arrangement, it can also be divided into three points in the front and three points in the rear.

Aircraft using tricycle landing gear require targeted training, mainly because instructors take into account the inherent heading instability of the tricycle landing gear.

The students have just finished studying aviation theoretical knowledge, and aircraft technology is still in the exploratory stage.

Facing many novices, the instructors gave priority to teaching the relatively simple three-point landing.

The so-called three-point touchdown means that the two main wheels and the tail wheel touch the ground at the same time, so that the angle of attack during touchdown is larger and the aircraft can land at a lower airspeed.

"Director Huang, look carefully, the plane is about to land. This is the student with the most solid theoretical knowledge in our aviation school. There is a high probability that he can enter the battle sequence."

Upon hearing Principal Chang's reminder, Huang He immediately raised his head and stared at the Fighter fighter.

With the aircraft aligned with the runway on final, it steadily descended at approach airspeed.

Judging from the stable fuselage, the student must have gently turned off the throttle and applied the rudder appropriately to maintain direction when entering the air above the runway.

The current situation made Principal Chang smile, and it was obvious that he was very satisfied with his students.

"Director Huang, am I right? Xiao Ma is a good youngster. Now the power of the plane has been reduced and the airspeed has begun to decrease."

"At this time, you need to pull the stick accordingly according to the speed of the aircraft sinking, the angle of elevation and the current altitude. The above operations are all to maintain the necessary lift at the angle of attack."

"Since the forward view may be blocked, students will use their peripheral vision to observe the relative positions of the ground on both sides and the aircraft to control the aircraft's descent rate."

"The last step is to land. Just before touching down, you need to increase the angle of attack to an attitude that allows the main wheel and tail wheel to touch the ground at the same time, and then touch down at three points at the same time."

After understanding the explanation, even a layman like Huang He can roughly understand the path to landing.

The fighter jet was perfectly positioned on the runway, and the whole process had an inexplicable sense of beauty. The students and instructors in the audience also began to applaud, and they were sincerely happy for the student who successfully landed.

But at this moment, the originally stable bi-wing fighter suddenly got chewed up. It seemed as if an invisible force was pressing down on the nose of the plane. In just a short moment, the propeller rubbed against the runway several times.

The sudden scene shocked most people, except Principal Chang and the instructors. Before Huang He realized what exactly happened, he had already led people to the scene of the accident.

"Hygienist! Come with me! Students, don't come and join in the fun, don't get close!"

Seemingly sensing Huang He's doubts, an instructor who had returned from the border took the initiative to explain.

"The main landing gear of the Fighter fighter is in front of the center of gravity and very close to the overall center of gravity. I guess Xiaoma must have applied a heavy brake during the taxiing stage, which caused the aircraft to be lifted directly due to the inertia."

"Director Huang, you should know how to ride a bicycle. The accident just now is equivalent to when riding a bicycle. Using the front wheel brake can easily cause the entire vehicle to roll over."

"So when taxiing, you have to brake lightly or tap hard until the speed is low enough before you can brake again. Oh, what a failure."

Fortunately, the Fighter fighter can be regarded as the final product among biplane fighters, and its protective performance is quite good.

After careful inspection by the health worker, it was found that the student named Ma had just fainted and did not suffer any physical injuries.

However, the situation of the plane was not good. The propeller had cut cracks on the runway, and there was already damage visible to the naked eye.

The engine hit the ground and the entire plane had to be repaired before it could be used again.

Ten minutes later, Principal Chang returned to the same place, his face looking a little ugly. After all, he had just vowed to introduce his students, but he overturned the next second.

Huang He took the initiative to break the silence. He patted Principal Chang on the shoulder and said:

"As long as everyone is fine, there is no need to worry about aircraft and fuel. Wait for up to four months, and by then there will be a new batch of better fighter jets and attack aircraft."

"Don't be anxious about training, you still have to proceed step by step. The comrades in the aviation school are the treasures of the border area, and we must ensure their safety as much as possible."

Learning to fly an airplane is difficult and dangerous. Unlike trucks or armored units, even if a mistake is made, there is a high probability that there will be no life-threatening injuries, usually injuries such as fractures.

But once the plane crashes, it is almost impossible to save. Before you master the skydiving technique, falling means death. What's more, there are many times when soldiers don't even have the chance to parachute.

The students of these aviation schools must have put in a lot of effort to complete the study of theoretical knowledge in just over a month.

Huang He knew without even thinking that these young comrades in their twenties must be studying hard during the day and continuing to chew on the knowledge they didn't understand at night.

Principal Chang nodded. He had also come all the way from the rookie stage and had experienced many things personally. After thinking for a moment, he came to the middle of the students.

"Students, I hope you can learn the lesson just now and avoid similar things from happening in the future."

"I would like to add that whether it is the three-point grounding that I learned a few days ago or the two-point grounding that will be used in the future, there is one issue that must be paid attention to."

"When touching down, the longitudinal axis of the fuselage must coincide with the direction of speed, or the center line of the runway. If the aircraft has a sideslip angle when the main wheels touch down, it will easily cause the heading control to diverge."

When all the students left the scene and continued to learn techniques from the instructors, Principal Chang asked the questions in his heart.

"Director Huang, do you have any work arrangements for coming to our aviation school this time? Are there any combat missions?"

"Although the students are not good enough, we instructors can definitely participate in the battle. The strength of the Fighter fighter is not much worse than the Japanese Type 97."

"And we have a numerical advantage. Judging from my experience in the Battle of Nomenkan, the enemy's army aviation rarely dispatches more than three flying squadrons at one time."

These questions made Huang He stunned. He didn't expect that Principal Chang, who looked very stable on the outside, was so eager to fight in his heart. But if you think about it carefully, you will understand that anyone who has been refrigerated for more than three years will be very eager for the battlefield.

"This is not a combat mission. You need to transport a batch of weapons to the south. We will set off tomorrow and you will select the personnel."

"I remember you went to study in the north in 2026, right? There is still one of our troops in the south. There is a bit of friction between the comrades there and the preserved fruits, and many bad things may happen."

"The border area has prepared a batch of new infantry light weapons. I need you to transport them there. The transfer airport has been arranged. Then you can just fly according to the plan. The Spitfire will be responsible for escorting them."

Although it is not a combat mission, it is a good thing to be dispatched. Principal Chang excitedly saluted Huang He with a military salute and shouted loudly:

"Promise to complete the mission!"

On the last day of 1940, 25 C47 Skytrains took off from the border airport. Carrying a full load of supplies and weapons, they flew south under the escort of 6 Spitfire fighter jets.
