Comrade, your ingredients are too complicated.

Chapter 198 First Batch for Fourth Master!

"Frontier Aircraft Factory: If we want to establish an independent aviation industry, then we must learn the technical methods of how to assemble aircraft and maintain existing aircraft.

Unlock time: 48 days

Effect: Obtain part of the materials of AVIC Xifei in 1958 (excluding jet aircraft), and obtain five researcher-level senior engineers.

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

Special Note: All manufacturers can be selected superimposedly, for example, the Sino-German Technical Mission and Morozov Design Bureau can be selected as tank manufacturers at the same time. "

After seeing the word Xifei, Huang He immediately felt that the trainer aircraft was not a problem. They are a big company that has developed and produced Feibao and Hongliu seriously.

Even if it is only the information of the propeller era, it is definitely enough to benefit researchers of the current era.

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

You must know that senior engineers at the researcher level are one of the highest ranks in the qualification titles of engineers in later generations. Even large companies with the level of Xifei only have 21.

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 will be able to develop and produce Chujiao-1941 and Chujiao-5 in 6.

But if it is really built, in this era, it is still more suitable as an advanced trainer.

After all, both of them are products of more than ten years later, and 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 too much beyond the current era as a primary trainer.

In Huanghe's plan, the future primary trainer aircraft of the border aviation school must be a biplane light aircraft with simple structure, easy to pilot, and low price.

Then after the baptism of the castrated horsepower version of fighter jets and Chujiao-5, fighters can basically officially enter the battle order of the First Air Division.

The reason for choosing Chujiao-5 is not the well-received Chujiao-6.

That's because the latter considered training pilots of jet fighters during the design stage, and the landing gear adopted the front three-point design, which is 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 three-point landing gear, the pitch-up of the nose can leave space for the large-diameter propeller, and the small tail wheel can also greatly reduce the structural weight.

This design fully complies with the industrial philosophy that the simpler, the more reliable, the safer.

----

In the busy work, the time came to December 12st.

Today is the last day of 1940, which means big news from the South is getting closer.

Although the fighters are not proficient enough to fly the C47 transport plane, but now the situation must overcome difficulties and start transporting aid materials.

After arranging the work of the first department, Wang Dexing drove from the bureau with Huang He to the airport in the border area.

When there were still 10 minutes away from the destination, the young security guard in the driver's seat suddenly pointed to the sky excitedly, and didn't even look at the road conditions for a while.

"Boss! Look! It's our plane! It's not a Spitfire! It's a fighter!"

No young man can refuse the temptation to soar above the blue sky. As a guard of the Yellow River, Wang Dexing has the opportunity to get close to every plane in the border area airport.

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

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

The biplane fighter in the sky is doing some basic flight maneuvers, it looks like the students of the aviation school are training.

"Drive a little faster, we have a high probability of seeing the landing process when we arrive at the airport now."

"Okay! You sit still!"

After arriving at the airport, Huang He told Wang Dexing to park in the parking lot first, while he went straight to the vicinity of the runway.The trainees and instructors who observed the take-off and landing of fighter jets were very sincere, and it took him a little effort to find Principal Chang from the crowd.

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

Originally, Principal Chang was staring intently at the fighter jet that was about to land, and when he heard someone talking beside him, he replied subconsciously:
"There must be accidents. We have been working hard to avoid casualties these days."

"It is currently the third day of training on the plane, and one plane needs major repairs. Yesterday, a trainee did not operate properly and broke the propeller and engine when he landed."

"Although people are fine, I feel sorry for the plane that broke down! It must be difficult for Director Huang to get so many planes back. It will be troublesome if you can't replenish them."

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

Many people think that taxiing is not difficult at all, just turn the engine up and slide.

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

The main reason is that the main landing gear of the aircraft is located in front of the center of gravity. Once the yaw moment is generated by the 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 students are overly nervous, it is easy to turn at a large angle if the rudder correction is not accurate.

Yesterday, it was because a fighter jet was taxiing too fast that the tires were knocked off and the landing gear was even broken.

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 party's arm to the position with the best view to watch the landing.

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

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

The trainees have just finished learning the theoretical knowledge of aviation, and the aircraft technology is still in the groping stage.

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

The so-called three-point touchdown is to let the two main wheels and the tail wheel touch the ground at the same time, so that the angle of attack when touchdown is larger, and it 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. He has a high probability of entering the battle sequence."

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

With the final alignment of the runway, the aircraft descended steadily at the approach airspeed.

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

The current situation made Principal Chang show a slight smile, and it could be seen that he was very satisfied with his students.

"Director Huang, I'm not wrong, Xiao Ma is a good seed. Now the power of the plane has decreased, and the airspeed has also begun to decrease."

"At this time, it is necessary to pull the lever accordingly according to the sinking speed of the aircraft, the elevation angle and the current altitude. The above operations are all to maintain the necessary lift for the angle of attack."

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

"The last step is the landing. Just before the touchdown, the angle of attack should be increased to the attitude that allows the main wheel and the tail wheel to touch the ground at the same time, and then the three points will touch down at the same time."

After an explanation, a layman like Huang He can roughly understand the way of falling.

The Gladiator cornered the runway perfectly, and there was an inexplicable beauty to the whole process.All the trainees and instructors also started to applaud, they were really happy for the trainee who landed successfully from the bottom of their hearts.

But at this moment, the originally stable biplane fighter suddenly gave a shit.It seemed as if an invisible force held the nose of the aircraft, and the propeller rubbed against the runway several times in just a moment.

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

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

Seemingly seeing Huang He's question, an instructor who came back from the border started to explain on his own initiative.

"The main landing gear of the fighter jet is in front of the center of gravity, and it is very close to the overall center of gravity. I guess Xiaoma should have applied a heavy brake during the taxiing phase, causing the aircraft to take the big jack directly due to the influence of inertia."

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

"So when taxiing, you have to brake lightly or gradually, until the speed is low enough to brake hard. Hey, it's really a failure."

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

After a careful inspection by the health staff, the practitioner surnamed Ma just passed out and did not suffer any physical injuries.

However, the situation of the plane was not so good. The propeller had forcibly drawn cracks on the runway, and there were already visible damages 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 original place, his face looking a little ugly.After all, just now he vowed to introduce his students, but the car overturned in the next second.

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

"As long as you have nothing to do, you don't have to worry about the aircraft and fuel. Wait for another four months at most, and then there will be a new batch of better fighter jets and attack aircraft."

"Don't worry about the training, you still have to proceed step by step. The comrades in the aviation school are all treasures in 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 they make mistakes, there is a high probability that they will not be life-threatening, and injuries such as fractures are usually caused.

But once the plane has an accident, it is almost impossible to save it. Before the skydiving technique is mastered, 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 about it. These 20-year-old comrades must study hard during the day and continue to study the knowledge points they don't understand at night.

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

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

"Let me add one more point. Whether it is the three-point grounding learned a few days ago, or the two-point grounding that will be used in the future, there is one problem that must be paid attention to."

"When touching down, the longitudinal axis of the fuselage must coincide with the speed direction, or coincide with the centerline 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 question in his heart.

"Director Huang, do you have any work arrangements when you come to our aviation school this time? Is there any combat mission?"

"Although the level of the students is not enough, we instructors can definitely participate in the battle. The strength of the fighter fighter is not much worse than the devil's [-]-style."

"And we have a numerical advantage. Based on my experience in the Nomenkan battle, the enemy's army aviation rarely dispatches more than three flying teams at one time."

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

"This time is not a combat mission. You need to transport a batch of weapons to the south. You will start tomorrow, and you will choose the personnel."

"I remember that you went to the north to study in 26 years, and now there is one of our troops in the south. The comrades there have a bit of friction with the fruit, and many bad things may happen."

"A batch of new infantry light weapons has been prepared in the border area, and I will trouble you to transport them there. The transit airport has been arranged, and you can fly as planned when the time comes, and the Spitfire will serve as the escort mission."

Although it is not a combat mission, it is a good thing to be dispatched.Principal Chang gave a military salute to Huang He excitedly, and he shouted loudly:
"Guaranteed to complete the mission!"

On the last day of 1940, 25 C47 Skytrains staggered off from Borderlands Airport.Carrying a full load of supplies and weapons, they flew southward under the escort of 6 Spitfire fighters.
