The U.S. Navy has a very urgent need for vertical take-off and landing fighter jets. In the 1980s, it conducted a lot of research, including Lockheed Corporation.
They need to put the engine at the back so that they can achieve supersonic flight, but they also need to have power for vertical takeoff and landing in the front. To this end, they have used their imaginations and come up with many creative ideas.
For example, the tandem fan engine is to elongate the aircraft engine and move the front fan part all the way to the front fuselage. There are nozzles on both sides. When the nozzles are deflected downward, they can provide the take-off and landing needs of the front fuselage. When the nozzle turns backward, it can provide the power to fly forward.
You can tell by looking at this design. This is a replica of the Sea Harrier. The engine of the Sea Harrier is cut in half and placed front and back. In fact, if the front compressor fan is turned 90 degrees, it will be a modern vertical lift. Engine layout plan.
However, this solution requires cutting the engine, which is equivalent to re-developing an engine. The technical difficulty is not small, so it has always stayed in the conceptual design stage.
Later on, someone else had a sudden idea.
It is too difficult to develop a new engine. If the engine is modified, it is to make some pipes on the top of the aircraft. The airflow ejected from the tail of the aircraft is transported to the front through these pipes, and a turbine is pushed in the front to convert the energy of the airflow into a turbine. The turbine rotates, and then the turbine drives a special lift fan, so that the power transfer can be completed.
Compared with the previous series fan, its biggest advantage is that it does not require modification of the engine, but its biggest disadvantage is that power is also transmitted through the airflow. The efficiency is too low and it cannot meet the needs of vertical take-off and landing fighters at all!
When McDonnell Douglas was developing a vertical takeoff and landing fighter, it also considered a lift fan solution, but ultimately gave up and decided to choose the safe Yak-141 lift engine solution.
At this time, Stanley stated this design plan. After Daniel thought about it for a moment, he shook his head: "No, the delivery efficiency of this plan is too low, and it is simply unable to meet the needs of the navy."
"What else can we do? We have seen Easterners display a drive shaft plan at an air show. If this plan can be successful, it will have to be modified. What if it is directly connected by a clutch?" Stanley asked .
Daniel instinctively wanted to shake his head. Even with two sets of drive shafts and a clutch that transmits 20,000 horsepower, it is not so easy to do it! But Stanley was already talking.
“It is still possible if our aircraft brake pads are used as friction pads.”
"That's right!" Daniel's eyes lit up: "The friction plates of the aircraft can withstand this kind of test. Moreover, in this way, the power is transmitted directly, without causing any loss of transmitted energy, and the heat can also be directly dissipated. As long as the program is written If it is done well, the power can be reliably connected and disconnected, and this technical route is more correct!"
After trying for so long, they finally found the correct power transmission solution! It's a pity that five years is a short time for this thing to mature, but it will take another five years to cooperate with the aircraft and mature the flight control.
Ten years from now, will there still be a market for them? Vertical take-off and landing fighter jets from the East are probably everywhere, right? In fact, they could not even wait until that time and were defeated by Boeing's X-32. After all, Boeing's progress was not slow.
Thinking of this, Daniel felt a sense of urgency again: "Then what are you waiting for? We will hold a meeting immediately to discuss the solution of this friction plate to transmit power. If everyone thinks it is feasible, we will start testing immediately!"
Damn Mingzhou Group, **** Mr. Qin, for deceiving them for so long!
Just when Daniel was cursing angrily, Qin Tao had already sent Tuji and his group away and arrived at an abandoned airport on the outskirts of the capital.
The location here is hidden and surrounded by villages. As long as a few necessary roads are blocked, it is almost isolated from the world. Moreover, the ground inside the airport is wide, which is very suitable for training. Therefore, this place was selected as a place for military parade training. .
The military parade teams are still being selected, but the simple barracks at this training ground have been built. The person responsible for the construction is the famous Mingzhou Group. They are not only shipbuilders, but also run other businesses, including infrastructure. And they all follow an international approach. For them, it would be even easier to transform this place into a military parade training venue.
Since the task was very important, Kong Laoer, who was in charge of infrastructure construction, came back from abroad and took charge of the project here personally.
Qin Tao did not intervene in the entire project and left it entirely to Kong Lao'er. After all, Kong Lao'er is now an experienced veteran. Even if he breaks away from the Mingzhou Group and sets up his own business, he can continue to stand firm and become the most famous person in the country. CEO of a construction group. Of course, Kong Laoer didn't have this idea. After all, without Qin Tao, he wouldn't be where he is today.
“President Qin, you are here.” Upon learning that Qin Tao was coming, Kong Laoer immediately ran over, accompanied by Leader Liu, the person in charge of the military parade training venue.
Leader Liu's official position is not small, and his military rank is also very high, but now, for this military parade mission, he is willing to come here to be a small village chief. Now that the army has not come in, he has been busy with him in the early stage.
“Well, Leader Liu, we are responsible for the entire infrastructure. If there is anything you are not satisfied with, just point it out.” Qin Tao looked at Leader Liu and said, “Our Mingzhou Group guarantees to complete the task.”
"We are very satisfied." Leader Liu said with a smile: "I participated in the military parade in 1984, and a military parade training venue was built here at that time. However, the conditions at that time were simply incomparable to those now."
Leader Liu was filled with emotions.
In 1984, this became a military parade training venue, and the original wasteland was transformed into a camp, using the most basic tents.
In the summer, the tent is as hot as a steamer! However, there was a tent to block the sun, so it was better. The temperature at the special training venue, which was a training ground converted from a track, was over fifty degrees.
At that time, I had no choice but to get on my horse and get some ice cubes to cool down. The time I looked forward to the most was rain. It’s cool after the rain. So, the more it rained, the more I trained. When my feet stepped on the rain, the sound of kakaka became louder. Great.
In addition to the temperature, there are also various natural environments. The surrounding areas are either farmland or wasteland. Therefore, various mosquitoes often appear, and there are more animals sleeping in the tent.
Thinking of the past and looking at the present, Leader Liu was very emotional.
“Mr. Qin, look, the accommodation area here uses the color steel plate developed by you. It is beautiful and durable, environmentally friendly and energy-saving, and can be reused.” Leader Liu pointed to the dark green barracks in the accommodation area.
The tents have disappeared, replaced by rows of neat accommodation cabins!
“This was developed by our Mingzhou Group?” Qin Tao looked at Kong Laoer. After all, he really didn’t know.
"Yes, Mr. Qin, when we are engaged in construction, we often need to stay on the construction site. The workers must have a suitable environment, so we worked with the steel factory to build this kind of prefabricated house." Mr. Kong Er introduced: "This type of board house uses polystyrene EPS sandwich panels, which are much better than the previous foam plastics. The outside is covered with our galvanized iron sheets. This is a new and efficient composite building material with good sealing performance. Whether it is cold winter or scorching heat, the people inside can be more comfortable. The internal frame is also specially designed by us. It uses the least materials, has the highest strength, and can withstand level 8 winds."
Speaking of these, Kong Laoer was gushing: "Actually, we have designed two-story or even three-story plans, but the space here is large enough, so we use single-story ones."
When constructing on a construction site, the accommodation of workers must be solved. This kind of board house is what their construction company needs most. Moreover, some construction sites are small in size and have a large number of workers, so they need two or even three layers of board houses. house.
This time the troops need to train in the training venue for the military parade, and it happened to bring this kind of prefabricated house. Anyway, after it is used up, it has to be dismantled and the site restored to its original appearance to be used as a combat readiness airport. If a reinforced concrete structure is used, It's not appropriate. Construction costs a lot of money, and demolishing it after use is another expense.
There is a large accommodation area here, with six rows of board houses forming one area. Office, dining, bathing, water, electricity and other supporting facilities are all available. The windows are also the latest plastic steel doors and windows. Wait, what is the hole reserved next to the window?
“According to the original design, each room also has an air conditioner. The air conditioner has not been transported yet, so it has not been installed.” Seeing Qin Tao’s eyes, Kong Laoer knew what Qin Tao was thinking.
"Winter training of Sanjiu and summer training of Sanfu are our precious spirit. However, after training, we should give the soldiers a suitable place to sleep so that they can train better the next day. This should also be taken into consideration, although it requires more It costs a lot of money, but these air conditioners are necessary,” said Leader Liu.
Qin Tao nodded: "It's a pity that our Mingzhou Group does not produce air conditioners. Otherwise, it would be no problem to give you a complete set of air conditioners. Just regard it as our contribution to the military parade."
Hearing Qin Tao's words, Leader Liu smiled: "It doesn't matter, these air conditioners will not be wasted. After the military parade is over, the air conditioners can be removed and installed in the army barracks. Mr. Qin, you come to bid and use the lowest price." We are very grateful for coming to build such a complete military parade training venue for us.”
"These are what we should do." Qin Tao said: "The military parade is to show the strength of our motherland, to show our national pride and self-confidence. Every soldier in the military parade is a meritorious official. We can provide some It’s also a great honor for me to provide logistical services. Hey, are there sewing machines here?”
Qin Tao walked to another room and looked at the row of sewing machines inside, very curious.
"Yes, the torn clothes and shoes of our soldiers need to be repaired." Leader Liu said: "In the past, during our 35th anniversary, the military parade training lasted for nine months. The first five months were at the station, and the last four months were in the military parade training. We have decided to extend the time of this military parade. Once you enter the military parade training venue, you will either be eliminated and leave, or you will leave after completing the military parade. This can often take more than half a year, and if your clothes are torn, someone will have to repair them."
In countless trainings, the cuffs will be worn when the arms are swinging back and forth, and the crotch will be worn when the legs are walking back and forth. As for the shoes that rub against the ground every day, many pairs will be worn out. Once they are broken, it is impossible to immediately Just replace it with a new one. If you can repair it and wear it again, you have to repair it. Diligence and frugality are virtues and can never be changed.
At this time, after hearing what Leader Liu said, Qin Tao was extremely emotional: "These soldiers participating in the military parade have worked hard in order to let the whole world see our military and national power."
"Yes, it is indeed hard work, but it is an honor for every soldier. From ordinary soldiers to generals, everyone is proud to participate in the military parade. Moreover, it also requires competition." Leader Liu continued: "In the 1984 military parade, we had a dynamic competition mechanism. Whoever's performance was unqualified would be eliminated and then replaced. It will be the same this time. Through competition, we will select the best." Come warrior."
"Everything has to compete, even soldiers have to compete. It's not easy." Qin Tao sighed: "By the way, why don't you see the equipment?"
“Mr. Qin, the equipment is at another military parade training venue. If you want to see it, I will take you there.” Kong Laoer said.
The foot formation and the vehicle formation cannot train together, otherwise the slogan "one two one" is shouted here and the rumbling noise is heard from the other side, making it impossible to train at all.
So, in addition to Shahe, there is another military parade training venue in Tongzhou.
This was originally a military airport, but later it was converted into a combat-ready one. It is useless and overgrown with weeds. Now it is used as a training ground for military parades. However, because the vehicle formations moved in later, the military parade training ground in Tongzhou is still We haven't started formal construction yet. We just need to build the military parade training ground in Shahe first.
However, several excavators, forklifts and other equipment were already at work, leveling the site. When Qin Tao and others came over under the leadership of Kong Laoer, this was the scene at the site.
"Unlike the training of the infantry phalanx, the vehicle phalanx pays attention to every second. During the training, the ground must be flat, so this initial work is also very important." Leader Li, the person in charge of the parade training site, has also is in place, supervising the land grading operations on site.
“For our vehicle phalanx, the training of ordinary soldiers should be simpler, right?” Qin Tao asked.
Ordinary soldiers in the foot phalanx train very hard, but for the vehicle phalanx, they only need to stand in a military posture and salute, and ensure the correct sitting posture after getting in the vehicle. The main core of the vehicle phalanx is the driver.
"That's right." Leader Li said: "In our professional terms, the main ones are line riding, card distance and constant speed."
Line riding is as simple as driving the car in a straight line. During the military parade, several marking lines will be drawn on the ground. All kinds of equipment ride on this line and move forward to ensure that this line is always there. The center of the car.
“According to our training requirements, when riding the line, the left and right error cannot exceed five centimeters.” Leader Li said.
Qin Tao nodded: "Such a request is not low. How did you do it?"
“Of course through rigorous training.”
They practice Sanjiu in winter and Sanfu in summer. Only the inertial memory formed by strict training can ensure that they have this kind of strength.
“This kind of training requires the use of specialized high-tech products.” Qin Tao sighed: “Have you considered using a satellite positioning system?”
"Mr. Qin, even if we use a satellite navigation and positioning system, the accuracy cannot reach centimeter level. Moreover, if we use this device, if we encounter an accident during the military parade and there is no satellite navigation signal, then we will You’re going to be caught blind.”
Hearing what Leader Li said, Qin Tao nodded with emotion: "Yes, you have a reasonable consideration."
The only mature satellite navigation system now is the American GPS, which uses two systems: military code and civilian code. The accuracy of the military code is within one meter, while the accuracy of the civilian code is within ten meters. This setting has been used until later generations. Therefore, using a satellite navigation device, you can only know whether the car is on the road, but not which lane it is in. Later, when Beidou appears, you will be able to obtain lane-level navigation capabilities.
However, even for lane-level navigation, the error is about one meter. Now it has an error of five centimeters. This is not the accuracy that satellite navigation can achieve. If it is really realized, it will not just mean opening the left window. Instead of hitting the right window, I hit the left eye without hitting the right eye. This is so unbelievable.
It cannot be satellite navigation, it can only be other methods.
“Leader Li, can you tell us more about the card distance and constant speed?” Zhao Ling was very interested.
"The card distance means that in a square formation, each vehicle must ensure that it is the same distance from the previous one, and the latter formation must also maintain the same distance from the previous formation. The error shall not exceed ten centimeters. Constant speed means moving forward at a constant speed, not going up and down suddenly.”
“Is it still maintained through rigorous training?”
"Yes, strict training. When we are training, we will put an egg on the accelerator pedal of the car. When stepping on it, the egg must not be crushed. This trains the driver's ability to accelerate or decelerate slowly." Li The leader said: "In order to ensure that the distance of the formation remains unchanged, we determine the distance between each other by drawing cross hairs on the reflectors."
“If it’s a tank, the requirements will be high,” Qin Tao said.
All kinds of trucks have reflectors, but tanks don’t have reflectors. Moreover, tanks will be more difficult to drive.
"Yes, tank training is more difficult." Leader Li said: "Especially a brand-new tank without previous training experience will be more difficult to control and requires a lot of training."
While he was talking, the roar of tanks came from behind. The sound of the high-pressure oil pump unique to diesel engines could be clearly heard in the roar of the engine. Upon hearing these sounds, everyone turned their heads and looked over.
Several tanks were driving over with black smoke. The angular turret, the high barrel, and the V-shaped wave guard in front of the vehicle were so clear that Qin Tao only glanced at them. He recognized it: "99 tank?"
“Ahem, Mr. Qin, this tank is currently called the Type 98. Don’t think that the one that was paraded in 1999 was the Type 99 tank.” Leader Li said.
In China, a lot of equipment is called Type 89, just to participate in the military parade that year. Unfortunately, due to various reasons, the military parade was not held successfully, so a lot of equipment could only be displayed in 1999. However, in tanks In terms of aspects, it is still a bit different.
When the tank was designed, it was called WZ-123, which was the project code name. In order to participate in the 1999 military parade, a batch of engineering prototypes were produced in advance. The entire project was also called Project 9910. However, the engineering prototypes produced were It became the Type 98, because it had already been built in 1998, but the number was not large, and it was not even enough to make up a square formation. Later, Type 90 tanks were needed to make up the number.
The designation of Type 98 was just a flash in the pan and soon disappeared in the long river of history. The Type 99 tank blossomed and became the most advanced tank in China and the world's leading tank.
At present, what Qin Tao has seen is only the initial test prototype.
The tank formation came over and stopped at the door. Then, some people jumped out of the tank. One of them staggered when he jumped. His sleeve was empty and he could not maintain his balance by swinging his arms. .
When he saw such a scene, Qin Tao was moved in his heart, and he strode forward: "Mr. Zhu, why are you here?"
"Mr. Qin, I didn't expect you to know me?" Mr. Zhu was very excited.
“Although our industries have no overlap, you are an old veteran in the military industry and I have heard of it a long time ago.” Qin Tao said, who doesn’t know the name of the one-armed commander? He respected the old man.
"Our tanks are newly developed, so we need to figure out how to train them in advance. I heard that the training ground here has already started construction and no one will bother us, so we plan to train here." Mr. Zhu looked at Leader Li : "Lao Li, we came here uninvited, you won't drive us away, right?"
"Lao Zhu, aren't you posing a problem for us?" Leader Li looked a little dissatisfied: "We have just leveled the land and haven't built the barracks yet. You are here like this, where will you live? How will you eat and drink?"
“Let’s set up our own tents and eat field food.” Mr. Zhu said: “Our tanks are running around the country and doing various tests. We have long been accustomed to being stationed in the field, so you don’t need to worry about it.”
“Since Mr. Zhu and others are in need, let’s set up a group of barracks within three days!” Qin Tao said.
Our title of infrastructure madman is not for nothing. We can build Vulcan Mountain within a week, and of course we can also build a base within a few days. What's so difficult about this?
Qin Tao is very confident.
“Then thank you, Mr. Qin.” Mr. Zhu said.
Leader Li still frowned: "Lao Zhu, you will break the rules. What if other troops imitate you?"
"Our equipment is new and has not yet been put into service in the army. It is different from other equipment." Mr. Zhu said.
“You have reasons, and so do others!” Leader Li said.
Sure enough, before he finished speaking, the roar of the engine came from the distance again.
Leader Li was a little helpless: "Look, someone is imitating you again!"
