897. Research and development of rockets
With Bai Shujie, the "great inventor", personally enumerating the parameters, Munn and his team did not waste time at all, nor did they use wind tunnel testing.
In just two months, a single-engine turbojet fighter and a twin-engine turbojet attack aircraft have been produced.
On April 23, 1940, the three pilots of the test flight team began a three-month demonstration flight of the demonstrator. This is the beginning of Bai Shujie's first-generation supersonic fighter, and it also pins hopes on him.
Because Horst and his core team had the basic experience of the Germans in studying steam catapults, the development of steam catapults for carrier-based aircraft went very smoothly.
At present, two sets of 35-ton steam catapults have been trial-produced and are being tested on two aircraft carriers HMS Ark Royal.
That is to say, it is now possible to catapult a weight of less than 35 tons with wheels out of 85 meters, and the instantaneous speed of the ejection can reach a maximum of 240 km / h.
In this way, the 2 aircraft carriers USS Ark Royal finally came in handy with a 97-meter short runway after a 224-meter glide long runway.
In the future, the warships of the two aircraft carriers will be composed, and the skid runway can be used to take off jet fighters; A short runway of 97 meters, which can be used to catapult medium-range bombers.
Because of the smooth development of the catapult, Bai Shujie finally had a clear idea where he had not been able to make up his mind. That is, 20 B-17 bombers and 20 DC-3 transport planes imported from the United States, all of which were structurally reinforced, and then replaced with twin-engine turbofan engines and converted into medium-range bombers.
The bomb load of the B-17 Flying Fortress was required to be increased to 12 tons, and the maximum take-off weight was 30 tons; The bomb load of the DC-3 bomber reached 6 tons, and the maximum take-off weight was 25 tons; The range is 7800 km, the maximum level flight speed is 950 km, and the level flight speed at an altitude of 8500 meters is 750 km.
This modification of Tong Guò completely got rid of the traces left by the Americans, and surpassed the American fighters and became the second trump card in their own hands.
In mid-May 1940, the Institute of Physics finally came with good news, which was also one of the technologies that Bai Shujie was most concerned about, and substantial progress had been made in rocket engine research.
On the basis of the artillery extended-range engine, the expert group of the Institute of Physics finally succeeded in the trial production of three rockets on a separate basis after a year of deliberation.
The diameter of the rocket body is 127mm, 388mm and 460mm, the length of the arrow is 1.2 meters, 2.4 meters and 3.6 meters respectively, the explosive loading capacity is 12.5 kg, 22.5 kg and 34.5 kg respectively, and the engine fuel is liquid. After top-secret tests, the firing range exceeded four kilometers.
As soon as Bai Shujie looked at these parameters, he knew that the heads of the experts were still stuck on various artillery. It seems that these experts are still preparing to launch these rockets with cannons, so as to achieve the purpose of increasing the range.
Although it is still a year behind the Soviets, this success is still of epoch-making significance, so Bai Shujie vigorously praised the expert group, but also put forward some guiding points:
"First, there is no need to limit the size of the original cannon caliber shells, and increasing the range and explosive power must be prioritized; second, it can be launched in orbit or from a canister; Thirdly, instead of considering the problem of manpower handling, a combat vehicle should be developed for combined launches to increase the coverage area. ”
With the foundation in place, the next improvements are much faster. After half a month, the expert group took out two more samples, with a diameter of 156mm and 324mm, and a weight of 480 kg and 720 kg respectively.
The engine fuel has been developed to the stage of solid fuel, using the orbital launch mentioned by Bai Shujie, and the charge has reached 25 kg and 36 kg respectively. After testing, the firing range reached 10.6 km.
Bai Shujie did not continue to find faults, but immediately ordered mass production, and two orders have been issued with a stroke of the pen:
The diameter of the 156mm rocket was changed to 136mm, and the weight was reduced to 360 kg. After improvement, mass production began immediately; The tractor-building plant, which immediately produced a half-track loader with a load capacity of 27 tons, equipped with an anti-aircraft gun 360-degree electrically rotating chassis, mounted on a 2×6 orbital launcher, capable of carrying 36 rockets.
In fact, Bai Shujie's requirements are not high, his goal is not determined in large-scale ground battles, and the number of rocket artillery does not need to be large. In his mind, there were two assault regiments, each equipped with 48 rocket launchers, to take the lead.
A launch vehicle, with the push of a button, 12 rockets went out. A salvo of 48 launchers is 576 rockets. If three rounds are fired in a row, it will be 1,728 pieces, with a total of 622 tons, and it is estimated that the enemy's forward positions, tanks and armored vehicles are in ruins.
It is equivalent to the strike strength of 480 155mm heavy guns, and it also exploded on the ground at the same moment, and no amount of heavy artillery can achieve this effect.
Of course, the biggest problem with rockets is that they are not accurate enough, so they must use numerical superiority to cover bombing.
To be honest, Bai Shujie's resources are limited, and he is more nervous than a little devil. Like the Soviets, hundreds of launchers bombed for five hours in a row, and Bai Shujie must have gone bankrupt.
What Bai Shujie needs is deterrence, not the destructive power of total destruction. At the right time, find a suitable place, take a proper action, and play the role of killing a hundred people, and his goal will be achieved.
At the same time, Bai Shujie gave the rocket team an order to develop an airborne rocket with a diameter of 105 mm, a range of 3,600 meters, and a weight of 180 kg.
Although it is not yet possible to guide and carry out precision strikes, each attack aircraft and fighter carries six rockets under the wings, which comes in handy when escorting bombers. When it is critical, the effect is still very impressive.
Bai Shujie can not be demanding, but the expert group, as a developer, always wants to improve its products. Especially a group of Jewish experts who returned from Germany, who knew that Germany had long been working on missiles.
Now that the rocket has basically succeeded, all that remains is to start anew research on missiles that can grasp the direction on the basis of the original Chinese people.
Worried about not getting support, the institute decided to ask Horst and Munn to come forward and find Bai Shujie to apply for the establishment of a "controllable bomb research laboratory".
Bai Shujie was amused when he heard it, but he didn't say it verbally, but changed his way: "Now that the research on transistor electrical components has made great progress, our control instruments are moving towards miniaturization and lightness, so it is indeed very necessary to set up a controllable bomb research laboratory." ”
"I decided to dedicate $8 million a year to this kind of basic research. Please start to set up a research laboratory as soon as you go back, and then report the development plan and research direction. My point of view is that if the first-stage rocket can't achieve the goal, it can actually be connected in series with more multi-piece staged acceleration. ”
"To be able to control the direction of flight, we actually need to add a seeker in front of the rocket, and then determine what sensors to use, and at the same time, our synchronization computer needs to be able to react."
"For now, radar guidance can be studied in depth. It is hoped that our experts can make some useful attempts in these aspects and accumulate more experience. ”
Bai Shujie knew in his heart that with the development of the times, the range of artillery became farther and farther. The range of the rocket artillery is too close, and the launcher is quickly destroyed by the intensive artillery fire of others, so no matter how many launchers are produced, it will be useless in the end.
If the range of the rocket does not exceed the range of 24 kilometers, the real power will not be reflected at all. Unless the troops are approaching the city and they have to carry out a stormy operation, the current 10-kilometer range can barely come in handy.
The only thing that can be used the fastest in terms of range is in airplanes. In air combat, with a range of more than 6 km, you will be able to control air supremacy.
On July 12, 1940, the navy of the little devils announced a blockade of coastal communications in Fujian and Zhejiang.
Bai Shujie immediately issued a telegram: "The waters of the Yellow Sea, the East China Sea, and the South China Sea have been the territorial waters of the Chinese nation since ancient times, and they have indisputable sovereignty and cannot be trampled on by anyone. All our descendants in China have the responsibility to safeguard national sovereignty. ”
"It is now officially announced that, without the permission of this commander, all ships passing through the East China Sea, the Yellow Sea, and the South China Sea will be sunk as hostile acts! From now on, the Commander will officially order the Air Force to begin air patrols in the waters of the East China Sea, the Yellow Sea, and the South China Sea. ”
In order to show his savings, Bai Shujie ordered 2 Nulong high-altitude high-speed reconnaissance planes and 2 DC-3 medium-range bombers that had just been modified into two groups to patrol every day, and immediately launched an attack when they saw the planes and ships flying the plaster flag.
In fact, Bai Shujie borrowed the topic to play, but it was just to divert the attention of the little devil. The blatant patrol is mainly to train the air force's high-altitude reconnaissance capability and train more pilots.
At the same time, strategic reconnaissance began in earnest against Okinawa, Taiwan, Luzon, Manila, Batangas, Palawan, Kuda, Kota Kinabalu, Bandar Seri Begawan and other places to see what the Americans, the British, and the little devils were doing.
The most important thing is to rehearse the airdrop problem. After half a month of continuous cruises, the airdrop of supplies to the task force of Bashigo has now begun.
In the past half a month, the little devil continued to swallow his anger and did not continue to speak. I couldn't bear it and couldn't do it, I once took off 6 of the latest Zero fighters twice, but I could only stare 1200 meters below the bomber.
Although Bai Shujie issued an announcement to shoot down the enemy plane, it is not yet timely. Until their own preparations are completed, the little devils cannot move until they do it to the Americans.
If the little devil does not make a move on Pearl Harbor because he intervenes too much, and lets the Americans hide behind and take advantage, this is something Bai Shujie will never agree.
MacArthur will not be punished as he deserves in the Philippines, tens of thousands of Americans will not die, and hundreds of thousands of natives in the Philippines will not be slaughtered, and Bai Shujie will definitely not stretch out his hand.
Little devils and Americans dog-eat-dog, this is the right pace of history. Bai Shujie will only hide behind and add fuel to the fire, and will definitely not take the initiative to bubble up as a savior.
However, the golden five-clawed flying dragon painted under the wings of Bai Shujie's two planes has been seen by many people. The little devil didn't completely figure out until today that the five-clawed golden dragon was Bai Shujie!
That means that all the warships near the Korean Peninsula are Bai Shujie's subordinates, and all the fighters are also Bai Shujie's troops.
In this way, the little devil was puzzled: when he was in Chengde, Bai Shujie did not have an air force, let alone a navy. It is even more impossible for there to be planes and warships on the Korean Peninsula, so where did Bai Shujie get so many experts back?
Don't understand.
After all, what happens next, let's see how it will be broken down next time.
