Chapter 198 The First Batch of Goods for the Fourth Master!

"Border Aircraft Manufacturing Plant: If we want to establish an independent aviation industry, we must learn how to assemble aircraft and the technical methods of maintaining existing aircraft.

Unlock time: 48 days

Effect: Obtain some data of AVIC Xi'an Aircraft in 1958 (excluding jet aircraft), and obtain five researcher-level senior engineers.

Enable manufacturer: AVIC Xi'an Aircraft, the effect is (aircraft production speed of military factories in the system: +15%, heavy fighter reliability +20%, tactical bomber reliability +20%)

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

After seeing the two words Xi'an Aircraft, Huang He immediately felt that trainer aircraft were not a problem, because they were a big company that seriously developed and produced Flying Leopard and H-6.

Even if it was just the data of the propeller era, it would 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 should know that the researcher-level senior engineer is one of the highest levels in the engineering qualification titles in the future. Even a large company like Xi'an Aircraft Corporation only has 21 of them.

If the Second Department 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 the CJ-5 and CJ-6 in 1941.

However, if they are really made, it is more appropriate to use them as advanced trainers in this era.

After all, both of them are products of more than ten years later. Now the ugly country is still using J-3 cubs to enlighten pilots.

It is more or less ill-considered to directly use a monoplane that is far beyond the current era as a primary trainer.

In Huanghe's plan, the primary trainer of the Border Area Aviation School in the future must be a biplane light aircraft with a simple structure, easy to fly and low price.

Then after the baptism of the castrated horsepower version of the Gladiator fighter and the CJ-5, the soldiers can basically officially enter the combat sequence of the Air Force First Division.

The reason for choosing the CJ-5 is not the highly praised CJ-6.

That's because the latter was designed to train pilots for jet fighters, and the landing gear adopted a front three-point type, which is very different from the mainstream rear three-point design during World War II.

Now all the aircraft on the battlefield are powered by piston propellers.

For aircraft with rear three-point landing gear, the nose can be tilted up to leave space for large-diameter propellers, and the small tail wheel can greatly reduce the weight of the structure.

This design is in full compliance with the industrial concept of "the simpler, the more reliable and the safer".

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

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

Although the soldiers are not proficient in driving C47 transport aircraft, they must overcome difficulties and set out to transport aid materials in this situation.

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

When there were still ten minutes to the destination, the young guard in the driver's seat suddenly pointed to the sky excitedly, and for a while he didn't even look at the road conditions.

"Director! Look! It's our plane! Not a Spitfire! It's a Gladiator!"

No young person can resist the temptation of flying in the blue sky. As Huang He's guard, Wang Dexing has the opportunity to get close to every plane in the border airport.

Although his cultural level is not enough to pass the entrance test of the aviation school, he still remembers the name of each aircraft.

After hearing the cheers of the guard, Huang He stuck his head out of the cockpit.

The biplane fighter in the sky is doing some basic flight maneuvers. It can be seen that the students of the aviation school are training.

"Drive a little faster. If we rush to the airport now, we will have a high probability of seeing the landing process."

"Okay! You sit tight!"

After arriving at the airport, Huang He told Wang Dexing to park in the parking lot first, and he went straight to the runway. There were really many students and instructors observing the takeoff and landing of fighters. He took some effort to find Principal Chang from the crowd.

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

Principal Chang was staring at the Gladiator fighter that was about to land. When he heard someone talking next to him, he subconsciously replied:

"There must be accidents. We have been trying to avoid casualties these days."

"It is now the third day of on-board training, and one plane needs to be overhauled. 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! It must not be easy for Director Huang to bring back so many planes. It will be troublesome if they can't be replenished."

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

Many people think that taxiing is not difficult at all. You just need to turn the engine up and taxi.

This view is a very common mistake. The ground taxiing of a rear three-point aircraft is like the artillery calculating the target distance. 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 the yaw moment is generated by lateral disturbance during taxiing, the ground friction will give the main landing gear a force in the same direction, which will further cause the yaw to intensify.

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

Yesterday, because a fighter jet was taxiing at too fast speed, the tires were all pulled off and even the landing gear was broken.

When he said this, Principal Chang suddenly realized that the person next to him was Huang He. He hurriedly greeted him, and then pulled the other person's arm to the best position 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 form, it can also be divided into front three points and rear three points.

Aircraft using rear three-point landing gear need to do targeted training, mainly because the instructors consider the inherent heading instability of the rear three-point landing gear.

The trainees have just finished learning aviation theory knowledge, and aircraft technology is still in the exploratory stage.

Faced with many rookies, the instructors gave priority to teaching the relatively simple three-point touchdown.

The so-called three-point touchdown means that the two main wheels and the tail wheel touch down at the same time, so that the angle of attack during touchdown is larger and the landing can be made 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. He is likely to enter the combat sequence."

Hearing Principal Chang's reminder, Huang He immediately raised his head and stared at the Gladiator fighter.

With the five sides aligned with the runway, the aircraft steadily descended at the approach airspeed.

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

The current situation made Principal Chang smile, and it can be seen that he is very satisfied with his students.

"Director Huang, I'm right, Xiao Ma is a good candidate. Now the power of the aircraft has been reduced, and the airspeed has also begun to decrease."

"At this time, you need to pull the stick according to the speed of the aircraft's sinking, the size of the pitch angle and the current altitude. The above operations are all for the angle of attack to maintain the necessary lift."

"Since the vision in front may be obstructed, the trainees will use their peripheral vision to observe the relative position of the ground and the aircraft on both sides to control the aircraft's descent rate."

"The last step is landing. Just before landing, you only need to increase the angle of attack to a posture that allows the main wheel and tail wheel to touch the ground at the same time, and then touch the ground at the same time at three points."

After the explanation, Huang He, a layman, can roughly understand the doorway of landing.

The Gladiator fighter landed perfectly on the runway, and the whole process had an indescribable beauty. The trainees and instructors in the audience also began to applaud, and they were happy for the trainee who landed successfully from the bottom of their hearts.

But at this moment, the originally stable biplane fighter suddenly came to a dog-eat-shit. It looked like an invisible force was holding down the nose of the plane, and in just a moment, the propeller rubbed against the runway several times.

The sudden scene frightened most people, but not Principal Chang and the instructors. Huang He had not yet reacted to what had happened, and he had already led people to the scene of the accident.

"Medical officer! Come with me! Students, don't come to join in the fun, don't get close!"

As if seeing Huang He's doubts, an instructor who came back from the border took the initiative to explain.

"The main landing gear of the Gladiator fighter is in front of the center of gravity and very close to the center of gravity of the whole. I guess Xiao Ma should have braked hard during the taxiing stage, causing the aircraft to be directly hit by inertia."

"Director Huang, you should know how to ride a bicycle. The accident just now is equivalent to riding a bicycle. Using the front wheel brake can easily turn the whole car over."

"So when taxiing, you should use light or tapping to brake until the speed is low enough to brake hard. Alas, it's really a failure."

Fortunately, the Gladiator fighter can be regarded as the final work of the biplane fighter, and its protection performance is quite good.

After a careful examination by the medical staff, the student surnamed Ma just fainted and had no physical injuries.

However, the situation of the plane was not very good. The propeller had scratched cracks on the runway, and there were already visible damages.

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

Ten minutes later, Principal Chang returned to the original place, and his face looked a little ugly. After all, he had just introduced his students with great confidence, but the next second, the car overturned.

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

"It's okay as long as the people are fine. Don't worry about the plane and fuel. Wait for four months at most, and then there will be a new batch of better fighters and attack planes."

"Don't worry about training, or step by step. The comrades in the aviation school are all treasures of the border area, and their safety must be guaranteed as much as possible."

Learning to fly an airplane is difficult and dangerous. Unlike trucks or armored units, even if you make a mistake, there is a high probability that there will be no danger to life, and generally it will be injuries such as fractures.

But once the plane crashes, there is almost no hope of rescue. Before mastering the parachuting technique, falling means death. Moreover, there are many times when the soldiers do not even have the opportunity to parachute.

These students in the aviation school must have put in a lot of effort to complete the theoretical knowledge learning in just over a month.

Huang He knew without even thinking that these young comrades in their twenties must have studied hard during the day and continued to study the knowledge points 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 center of the students.

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

"Let me add one more point. Whether it is the three-point landing learned a few days ago or the two-point landing to be used in the future, you must pay attention to one problem."

"When landing, the longitudinal axis of the fuselage must coincide with the speed direction, or with the center line of the runway. If the aircraft has a sideslip angle when the main wheel touches down, it is very easy to cause the heading control to diverge."

When all the students left the scene and continued to learn technology with the instructor, Principal Chang asked the question 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' level is not enough, we instructors can definitely participate in the war. The strength of the Gladiator fighter is not much worse than the Japanese Type 97."

"And we have the advantage of numbers. Based on my experience in the Battle of Nomonhan, the enemy's land aviation rarely dispatches more than three flight squadrons at a 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 after thinking about it carefully, he understood that anyone who has been frozen for more than three years would 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 that you went to the north to study in 1926. There is still a unit of ours in the south. The comrades there have some friction with the preserved fruits, and many bad things may happen."

"The border area has prepared a batch of new infantry light weapons, and I have to trouble you to transport them. The transit airport has been arranged. When the time comes, you just need to fly according to the plan. The Spitfire will serve as the escort mission."

Although it is not a combat mission, it is a good thing to be able to go out. Principal Chang excitedly saluted Huang He, and he shouted:

"Guarantee to complete the mission!"

On the last day of 1940, 25 C47 sky trains took off from the border area airport. They were fully loaded with supplies and weapons, and flew towards the south under the escort of 6 Spitfire fighters.
