In the next two days, Zhou Zhihan guided the pilots every day how to fly Martin and bombard him again.

Commander-in-chief General Zhou Zhirou said that Martin's heavy bombing is a country's important weapon, and there must be no mistakes when transferring from Nanjing Airport to Nanchang.

Zhou Zhihan was very modest. At the beginning, he called every pilot a senior.

But Gao Zhihang and the others felt unhappy when calling him senior, and they felt that they had suddenly distanced each other.

Senior,

Very vulgar.

Call it a name.

Call me brother.

You can't call it a senior.

Our technology is a bit ashamed to be called a senior by you...

OK.

Zhou Zhihan was helpless.

Just call me brother!

In the past two days, the pilots have been discussing the maneuvering movements of top students flying every day.

They are all flying old birds, knowing their abilities.

Everyone knows that they cannot meet the technical requirements of top students and cannot fly the fallen leaves and move. If they forcefully fly, the plane will be destroyed and the people will die.

Facing Gao Zhihang, Zhang Mufei and other pilots, Zhou Zhihan was not only respectful but also respectful. They were all heroes of the country. Moreover, Zhou Zhihan is currently still in the rank of sergeant. He has too little qualifications in front of a group of senior pilots such as lieutenant colonels, majors, captains, etc.

But Gao Zhihang and others don't think so.

The flying skills of top students shocked them and made them see a state that they had never seen before and could not imagine, and they dared not imagine.

Chinese Air Force pilots humbly learned from Zhou Zhihan, and from him, they could learn flight knowledge they had never seen before.

Zhou Zhihan has been eating and sleeping with Gao Zhihang and others these days, and has a deep understanding of these heroes.

But this understanding is painful.

Zhou Zhihan could not change the current passive situation of China's war of resistance, nor could he save the lives of heroes such as Gao Zhihang.

The fighter plane needs to be launched and needs to be driven by a man.

war.

Many people need to sacrifice their lives.

Therefore, every time Zhou Zhihan learns about these pilots, his inner pain will increase by ten.

The greatest uncertainty in life is that you don’t know when, where, and how you will die.

But Zhou Zhihan knew when, where, and what kind of tragic way would a hero like Gao Zhihang leave.

Therefore, Zhou Zhihan must express enough respect to these heroes.

As long as they ask about flight knowledge, Zhou Zhihan will explain in detail and patiently, and sometimes he will fly into the sky to demonstrate himself.

After several days of contact, Zhou Zhihan truly realized that the current training level of Chinese Air Force pilots is too low and too backward.

The flight knowledge and skills they learned remained seven or eight years ago.

Due to the weak country and the lack of diplomacy, coupled with the domestic poverty and backwardness, it is difficult for Chinese Air Force pilots to go out and communicate, learn and discuss with pilots of the world's aviation powers.

This direct result is passive self-sustainment.

The inability to communicate with pilots from various military powers to discuss and learn advanced flight technologies directly leads to the lack of innovation for Chinese pilots.

In addition, the aircraft is losing a lot, fresh blood pilots have seriously insufficient flight time and their basic skills are not solid enough, so where can innovation come from?

For example, the current Chinese pilots' use of air shooting sights is still at the level of seven or eight years ago, and has been left behind by the ever-changing fire technology in Europe and the United States.

Zhou Zhihan explained to the pilots day and night the advance shooting and the use of machine guns:

The earliest aerial shooting sights were stationary sights.

The pilot can aim along the axis of the gun barrel through the sight's sight's sight's sight.

For example, when the pilot finds that the wingspan projection of the enemy aircraft accounts for half of the aiming ring, he can judge that the aircraft has entered the maximum effective shooting distance...

Rings are also useful tools for estimating advance quantities.

Within a certain distance, the early angle required for shooting for a flying target that moves at a constant speed is related to the projection of the target...

When the cross angle of the target machine head or the cross angle of the wing is very large, shooting the target requires establishing a larger advance angle, which is called - large deflection angle shooting...

Gao Zhihang and the others listened very carefully to the new knowledge brought by Zhou Zhihan. Many people took out notes and recorded the most advanced technical concepts in detail, and took them back to teach other pilots. These explanations were too advanced and improved them a lot.

Zhou Zhihan wished he could teach all his knowledge, but due to limited time, he could only pick up some of the most important skills and explain them to the pilots in the simplest and most obvious way.

In order to prevent the secret of the Sun Yat-sen Mausoleum Airport from being discovered by the Japanese, in addition to practicing Martin’s heavy bombardment flying over the airport, we also demonstrate the most critical technique to everyone, which is the use of the artillery:

In order to use aerial artillery to destroy enemy aircraft, attack aircraft must meet the requirements of distance aiming conditions and shooting timing.

The maximum effective range of the air cannon depends on many factors, mainly including ballistic parameters, aiming accuracy, fuse requirements, and the degree of solidity of the projectile spreading the target.

Aerial shooting is roughly divided into two categories, one is tracking shooting and the other is fast shooting.

When the center of the halo stays at the expected aiming point for a longer time than the stable aiming time, use the tracking shooting method.

Fast shooting, also known as blocking shooting.

The interception is mainly suitable for situations where the center of the ring can only pass through the expected aiming point but cannot stay for a long time.

When tracking shooting, stable tracking is essential for the front sight to accurately calculate the required advance angle.

Stable tracking can greatly increase the probability of hitting...

Due to too many unstable factors after the July 7 Incident, Martin must leave as soon as possible.

On the third day, Gao Zhihang and others drove the Martin 139wc heavy bomber away from the temporary airport of Nanjing Zhongshan Mausoleum and headed to Zhoujiakou to station, which was far away from the attack distance of the Japanese aircraft. The pilots also needed to hone their skills in driving heavy bombing.

No matter how good the heavy bombing is, it must be driven by an excellent pilot to exert its strongest power.

Watching Gao Zhihang and the others driving Martin 139wc to disappear into the horizon, Zhou Zhihan felt melancholy in his heart. He didn't know if there would be a goodbye in the future after this farewell.

Today is July 12, 1937, and there is still a whole month before the fierce and great Battle of Shanghai.

In this month, no one can change China's passive backwardness, and no one can change the fate of everyone.

Zhou Zhihan originally wanted to fly to Zhoujiakou with Gao Zhihang and the others.

But Zhou Zhirou said in private that she would take him to Lushan in a few days to attend a meeting about China's future life and death.

So Zhou Zhirou asked Zhou Zhihan to rest well at home these days. He had just returned from the United States and had not stayed for a day, but he was instructor day and night, teaching the flying old birds to fly Martin to bombard him again. Now that the mission is completed, it is time to go home to spend time with his family.

Finally, Zhou Zhirou said earnestly: "It won't take long, maybe we don't have time to have a few more stable meals with our family."

If it were someone else, it might not know what Zhou Zhiruo said, but Zhou Zhihan knew, and he knew more than everyone else.

Zhou Zhihan felt that it was time to think more about the safety of his family.

After the Battle of Songhu started on August 13, by the end of November and early December, the NJ defense battle that shocked the world will begin again.
Chapter completed!
