In the secret munitions factory of the National Defense Army, Tu Qianjun saw Shen Hong with a tired face. And this engineer, who was regarded as a technical plug-in by Tu Qianjun, was looking at his master, Jia Xiaohou, distressedly.

Jia Xiaohou gave Shen Hong a comforting look, and then smiled at Tu Qianjun and said, "It's finally lived up to expectations, the modification has been completed." ”

As he spoke, Jia Xiaohou took Tu Qianjun and Liu Yunjiao through the main roads and came to a venue. There were two fighter planes parked there, and Jia Xiaohou said to Tu Qianjun tiredly.

"These two are our improved ground attack planes and interceptors, one is specially used to clear the enemy's positions with fixed-point fire, and the other is a fighter and bomber specially used to intercept the enemy."

As he spoke, Jia Xiaohou walked to the plane on the left, and his tired face showed a hint of pride from the bottom of his heart!

"This is our improved version of the strong volley, I call it 'Tiger Shark Type A'! Its maximum take-off weight is 3,800 kg, its maximum speed is 680 km/h, and its ceiling is 13,500 meters! ”

I have to say that Jia Xiaohou is extremely serious and responsible for his work! In order to do a good job of improvement, he has now even become a complete aviation expert! Every bit of data is reported with such confidence!

This self-confidence comes from his professionalism and years of hard work and experimentation!

"The standard armament is four 20mm 110 cannons, each with 150 rounds of ammunition. There are chutes on the wings, and you can choose to equip 4 combinations of 6 70mm air/ground rockets, which can be discarded after launching......"

The more Jia Xiaohou's eyes lit up, and his lips trembled! Shen Hong and the others next to him raised their chests and looked at the fighter with pride!

"The weight has increased, which leads to a decrease in the combat radius. The current range is only 750 km, but if you carry a pair of 250L drop fuel tanks, the maximum range can be increased to 1200 km! ”

"Also, in order to guard against the machine gun of the Japanese army's 710th chapter of hard work, we have specially strengthened the cabin glass! The front shield glass is multi-layered 60mm thickness bulletproof glass, which can defend against 12.7mm machine gun bullets in a short time! Hey! Little Japan's 7.7 machine gun wants to penetrate it! ”

The development of this glass is a breakthrough. This is Jia Xiaohou's own improvement based on the safety glass of Benedites in France. Although the weight has increased, it has a greater chance of survival for the pilot.

At the beginning of the 20th century, a Frenchman named Benedites accidentally knocked a glass bottle off a shelf while sorting out chemicals. With a crisp sound of "pop". The glass bottle fell heavily to the ground.

Benedites secretly complained, oops, the medicine must have been splashed all over the floor, and it would take time to clean and wash it again. Just as he lowered his head and bent down, ready to clean up the mess, he unexpectedly found it. Although there were several cracks in the glass bottle, it did not shatter and the medicine inside was intact.

At that time, most of the buses and cars in France used ordinary glass, which caused the consequence that once a car accident occurred, the broken glass would cause passengers to scratch, and even some people died.

Benedites saw a possibility in the bottle, which only cracked but did not break into pieces: glass, if specially treated, would be much safer!

Eventually, Benedites developed the world's first safety glass. This glass is sandwiched with cellulose trinitrate grin, and the sides are filled with ordinary glass, which is subjected to violent impacts. It will only shatter and not splash. This led to the creation of the world's first bulletproof glass.

In history, Zhang Zuolin had his own bulletproof car, and even Zhang Zuolin added a heavy machine gun to the car as a fire support. Han Fuyu also purchased an armored car from the United States

The car has double-layered bulletproof glass, and the chassis and body are all armored. It takes 12 cylinders to drive. And Chen Tiaoyuan's son Chen Du also ordered a similar car from the United States in order to please his father, but the performance was better.

It was a 16-cylinder Buick armored bulletproof car that cost more than 10,000 dollars to customize, and Chen Tiaoyuan liked it very much but never dared to sit on it. There's no way, isn't it jealous that you don't even have Jiang Zhongzheng to sit there?!

Jia Xiaohou, on the other hand, based on bulletproof glass purchased from the United States, researched and improved it on his own and equipped it with fighter jets. Now the three eastern provinces have their own chemical base, Fan Xudong and others continue to expand production capacity and research and development under a large amount of financial support, and at the same time, the market has a special person responsible for development, and the entire chemical industry has formed a virtuous circle.

Tu Qianjun was also very satisfied with this design, and for a long time, Japanese fighter guns would definitely not reach more than 7.7mm. In other words, there is basically no chance of shooting down the Wehrmacht except for their luck in hitting the fuel tank!

"Uncle Jia, how much does that discardable rocket launch slot cost?!" Tu Qianjun asked this question. He feared that if the cost was too high, the IDF might not be able to afford it.

After all, the foundation is still thin, and once the big war starts in the future, the consumption will be amazing! So cost becomes a real issue that has to be considered.

"Since our launch slot is disposable, the cost will naturally not be high!" Jia Xiaohou said with a smile, how could he not know that the foundation of the three eastern provinces was not thick?! This was also taken into account when making this weapon.

"The transmitter uses bakelite, which is urea-aldehyde plastic. Inside, a thin steel tube made of 0.8 mm seamed steel tube is used as the launch tube. This is very light, weighing only 3 kilograms. The cost is also not high. Let's make a batch by ourselves, about 2~3 yuan. ”

Now Tu Qianjun is completely satisfied, the price is not high, and this is still equipped. That is to say, in fact, it depends on the situation, even if the 20mm caliber cannon is not installed, it is enough to shred those thin-skinned fighters of the Japanese army!

Jia Xiaohou said and walked to the fighter on the right, and said to Tu Qianjun: "There is also this, this one we call the 'Tiger Shark B Ground Reinforcement Attack Aircraft'." ”

Saying that, Jia Xiaohou paused and continued: "The parameters are basically the same as those of the Tiger Shark Type A, but what we have added is to strengthen the landing gear, strengthen the wing structure and pylons carrying capacity, and install deceleration flaps for dive bombing. At the same time, a controllable speed brake is installed at the tail. ”

Tu Qianjun didn't understand these terms, but he obviously felt that this fighter was used for ground dive bombing!

"The Tiger Shark B's body is reinforced with double-layer gap armor plates on the lower side of the important parts, self-sealing fuel tanks, and spare rudder operating ropes. At the same time, manual fire extinguisher nozzles are installed at the engine and fuel tank positions, and the spare load is discarded and switched. Its tires are large, low-pressure tires. And add armor plates under the driver's seat to ensure the safety of the aircraft. ”

Tu Qianjun listened and nodded continuously, and Jia Xiaohou became more and more proud when he saw this! His hard work has been affirmed by others, which is a very happy thing for a person who specializes in technology!

"Tiger Shark B, our standard armament is four 14.5mm large-caliber machine guns, each with 300 rounds of ammunition. It can also be equipped with optional weapons such as 8x105 ground rockets, 3x250kg bombs, 2x500kg bombs or 2x40mm external anti-tank guns, which will occupy all the fuel tank pylons and reduce the range. If you don't have bombs, then it's enough to equip you in battle. ”

Tu Qianjun couldn't help but nodded, 4 14.5mm machine guns were enough even for an encounter. Unless it is used for bombing, the benefits of carrying bombs outweigh the losses. It's good to use it for ground support.

"Uncle Jia! You've done a great job! Looking at these two fighters, he turned around and saw Jia Xiaohou's pale and tired face, and Tu Qianjun's heart suddenly swelled with a trace of warmth.

"When will these two fighters be ready for full-scale production?!" After a pause, Tu Qianjun said to Jia Xiaohou. And Jia Xiaohou smiled when he heard this: "We have been to our four aircraft production plants to inspect, and now the technological level has been improved, and the output is naturally increasing." ”

"I dare not say more, but it is still possible to achieve 300 aircraft a month with quality and quantity." Tu Qianjun nodded fiercely, and then said, "That's good!" I'll just order them to go down and let them step up the acceptance! Once the Air Force deems it suitable, it will be fully reloaded! ”

Jia Xiaohou smiled! He laughed like a child, but after laughing for a while, he actually lay down on his back! Tu Qianjun's face changed, and he hurriedly supported the engineer, but he closed his eyes when he saw him with a smile on his face.

Tu Qianjun said loudly with red eyes: "Uncle Jia! Uncle Jia! Liu Yunjiao! Get me a doctor right away!! ”

Shen Hong watched his master cry and intermittently talked to Tu Qianjun about the hardships of this time. Jia Xiaohou is not young, but in order to make the modified new fighter go online as soon as possible, he pulled the whole team to modify the design day and night.

For a few months, Jia Xiaohou and the entire team only rested for less than three hours a day. The rest of the time was spent on the improvement of the two Tiger Shark models.

In Shen Hong's whining and crying, the doctor affiliated with the Ordnance Institute hurriedly arrived. carried Jia Xiaohou to the infirmary, and after a careful examination, he said to Tu Qianjun with a smile: "Chief Engineer Jia has no physical problems, but he is too tired." It's a little weak, and I need to make up for it......"

And while talking, the whole infirmary was snoring! Tu Qianjun and Liu Yunjiao raised their eyes, and the R&D personnel who accompanied them to check the aircraft were all leaning back on their chairs and falling asleep!

Tu Qianjun, who saw these researchers asleep, was silent, and asked the guards to find stretchers to send all these researchers back to the dormitory, and carefully close the quilts for them.

The chef was asked to carefully make dietary therapy and tonic for these researchers, and at the same time, Liu Yunjiao instructed him to go down and purchase a batch of old ginseng and come back to make ginseng tea for them.

At the same time, the rest of the management personnel of the munitions factory were instructed to give all the officers a five-day holiday.

Back at the headquarters, Tu Qianjun sent a telegram to Air Force Commander Chen Haihua: "Go to the Ordnance Institute to accept the new fighters, and gradually change them if you can." Stalin's order, it seems that we can take a little more! ”rs！！！
