Su-27sk No. 02 is equipped with giant pesticide sprayers that look like auxiliary fuel tanks. The seven giant pesticide sprayers can carry five tons of pesticide liquid. Calculated based on the dosage of 30 kilograms per acre, it is enough to spray more than 160 acres of land.
, based on a width of 500 meters, it can operate for about 220 kilometers.
So Li Zhan misunderstood what Deputy Director Zhong meant. He only calculated the range of the fighter plane, but did not take into account the factor of liquid medicine. Deputy Director Zhong just wanted to give Li Zhan a more specific understanding of the operating distance.
If you spray continuously, it will take two rounds.
In fact, not only did it have to fly at least six times, but it also had to land no less than seven times to replenish the medical solution.
Li Zhan was mentally prepared to fly for eight hours straight.
What made him feel troublesome was that Deputy Director Zhong proposed to spray after the sky darkens. Because this kind of pest likes darkness and basically does not come out during the day.
Long-distance, low-altitude, low-speed flight at night is definitely a difficult flying subject. Li Zhan didn't bother to rest, and repeatedly and carefully studied the terrain and landforms the route passed through. The 101st Brigade rarely flew here to engage in low-altitude flight training. Li Zhan
My familiarity with the topography here is far less than that of the Beiku Mountains.
He had just crashed a J-10a, so he did not dare to take it lightly, and repeatedly reminded Miao Yu to check the condition of the two engines of the aircraft. If anything was wrong, he would report it and apply for a replacement aircraft.
Two hours before departure, Deputy Director Zhong came to Li Zhan, explained the key points again, and then said, "Captain Li, you have to work hard tonight. After you finish here, our technical staff will stay overnight
Check the condition of the isolation belt and try to get the results out before dawn. If additional spraying is needed, I will report it immediately."
Li Zhan smiled bitterly and agreed, "I promise to complete tonight's mission!"
That's all he could say.
After an eight-hour flight, even if he was strong, he would be paralyzed. He would not be able to come for the second eight hours during the day tomorrow.
Li Zhan asked, "Yes, since the pests like darkness, will supplementary spraying during the day tomorrow be effective?"
"Yes. It's just that spraying at night is most effective. We are racing against time. We must open up the isolation zone in the shortest possible time, and we must have immediate results." Director Zhong said.
Li Zhan fell into deep thought.
He seemed to have thought of another way, so he couldn't help but look at the time again, and then quickly calculated. The time should be enough. At worst, it could be delayed by an hour or even two hours, but he could still complete the task ahead of schedule.
After making the decision, Li Zhan said, "Director Zhong, I have a faster way."
Director Zhong was suddenly pleasantly surprised, his eyes sparkled, and he asked excitedly, "What can we do?"
"Increase the number of aircraft on missions." Li Zhan said with a smile. "To save time, all the chemical liquids are installed in sprayers. There are enough sprinklers, but the only thing missing is the aircraft, right?"
Director Zhong said, "That's right. We have doubled the redundancy of sprinklers and chemicals at all costs."
Li Zhan said, "I can solve the problem of the aircraft. Bring all the sprinklers and use segmented relay spraying in a saturated state, which can greatly shorten the time to open the isolation zone. According to my estimate, it can be completed within two hours."
Complete the development of a 700-kilometer isolation zone."
shortened by six hours.
This is almost equivalent to saving thousands of acres of cotton fields.
"Can you dispatch more planes?" Director Zhong asked excitedly.
Li Zhan nodded solemnly, "No problem at all! If you agree with my plan, I will immediately report to my superiors."
"Agree! Agree! Captain Li, you have really helped us a lot! The six hours you spent saved the losses of hundreds of farmers!" Director Zhong was so excited that he had tears in his eyes.
It is difficult for people who have not experienced natural disasters to understand such feelings. Director Zhong, who was born in a farmer's family, is also a technician on the front line when agricultural natural disasters come. He knows very well that every hour he strives for at this moment is very important.
How important is future disaster resistance and how much loss can be recovered.
Li Zhan did not waste time and immediately requested instructions from the brigade for a report. After receiving the report from the duty room, Xue Xiangdong immediately requested instructions from the duty chief of the military region's air force. After receiving approval, the Beiku War Training Base sounded an emergency dispatch alarm. All members of the Falcon Brigade were able to fly
All the fighter planes were mobilized, and the combat readiness duty task was temporarily handed over to the Second Brigade.
Just ten minutes later, the Air Force approved the plan of the 101st Brigade. Xue Xiangdong gave the order, and ten Su-27 fighter jets took off one after another and transferred to the South Library Station. At the same time, two Army Air Forces stationed at the North Library Combat Training Base
The Mi-171 carried four maintenance crews and quickly transferred to the Nanku Field Station to participate in the support work of the fighters. Shi Zezhong had received the order long ago, so the Nanku Field Station also began to pull up, and the fleet must arrive at the transfer airport.
Make all logistical preparations beforehand.
In less than an hour, all the units were in place, and Nankuchang Station suddenly became lively, and it seemed a bit crowded because there were eleven heavy fighter jets stationed there. It was only 7 o'clock in the afternoon, and it was at least more than an hour before dark.
time.
Although this is already the speed of Beiku, Li Zhan still believes that there is a lot of room for improvement in reaction speed. You must know that this is only less than 300 kilometers apart. If it is a transitional operation with a distance of thousands of kilometers, it will need
How long?
The maintenance support team is the last to arrive. If Nanku Station has the ability to support the Su-27, the transition time will be reduced by half...
The entire Falcon Group's fighter planes have been transferred to Nanku Field Station, and Li Zhan is no longer the mere commander.
The sprinklers are all ready-made and manufactured exactly according to the Su-27 pylon, including the circuits, all of which are specific to this aircraft model. A sprinkler that can be sprayed by the Su-27 fighter jet is manufactured from scratch.
It only took one day for the relevant factories and the Beiku repair shop to complete. Such manufacturing potential is unique.
After the maintenance team arrived in place, they immediately began to inspect the fighter aircraft, then attached the sprinklers, and then repeated the inspection. This preparation work was completed faster than Li Zhan expected, and some time was gained.
Accompanying the maintenance detachment was a command team led by Bao Guanhua, who stationed at the tower of the South Library Station, and relied on the advantage of being the closest to the South Library Station to direct the pesticide spraying operation. Xue Xiangdong was on duty at the North Library War Training Base, and after dispatching a
When a large group of fighters is transferred to other areas for combat, Bao Guanhua can only take charge, and any deputy position will not suffice.
Whether it is the Second Division or the Three Hundred Division, if their units above the organic flying group are stationed in Beiku for training, they will either be led by a military chief or a political officer, but there will be no third candidate. And the flying group and above will fly across regions.
Training must be approved by the high command, and mere filing is absolutely not enough.
This was the first time that Li Zhan saw Political Commissar Bao commanding military operations. Even flight training operations were very rare, at least Li Zhan had never seen it before.
When he arrived at the tower, Bao Guanhua and the combat staff were analyzing several maps on the combat table with serious expressions. There were aeronautical maps and crop distribution maps provided by the agricultural department. Even the largest one was actually
Very clear satellite photos.
"Li Zhan, come here." Bao Guanhua raised his eyes and pointed at Li Zhan.
"yes!"
Li Zhan saluted and ran over. He didn't dare to smile in front of Bao Guanhua. The whole brigade knew that the political commissar was a very strict and principled person. To put it bluntly, he was not easy to get along with and had rigid ideas. Not very good.
I like political commissar Bao, but I am most afraid of political commissar Bao, who is known as Bao's black face.
Xue Dabaobao Heimeian soon became a famous golden partner in the Air Force aviation unit.
"This is the battle plan. We have divided the 700-kilometer isolation zone into three sections, each section is 230 kilometers long. Four fighter planes are arranged to operate simultaneously in each section, carpet spraying, covering a two-kilometer-wide cotton field at one time.
"Director Zhong made it clear that the best results are achieved when the operating error is minimized at the same time." Bao Guanhua briefly introduced the plan.
Li Zhan agreed with this combat method. He raised a small question, "But the range of the liquid medicine carried in each sortie is only theoretically 220 kilometers."
Bao Guanhua said, "You take the first batch to carry out the first section that is the closest. After completing the operation, you will return immediately to replenish the medical solution and then take off again as a reserve team. The first section is only a few dozen kilometers away. After you return and land, you will at least
There are still six tons of aviation fuel, which is enough to carry out replenishment operations on any section."
"I understand, political commissar, I am determined to complete the task!" Li Zhan straightened his back.
Bao Guanhua said solemnly, "The latest report from the meteorological station shows that the weather has turned cloudy and the clouds are very thick, but the low-altitude wind direction and wind strength have not changed much. The main problem is visibility. All fighter planes are flying at low altitudes, with an altitude of 150 meters."
Between ten meters and two hundred meters, avoiding collisions during operations is the top priority."
Li Zhan said with confidence, "Please rest assured, political commissar, all pilots in the Falcon Group have excellent results in non-altitude air combat subjects. They are very good at low, medium and high altitudes. There will definitely be no collision accidents!"
"I suggest allocating height." Bao Guanhua said with a frown.
Li Zhan thought for a while and said, "The optimal spraying height is 150 meters. I plan to have all fighter planes operate at this altitude. Everyone is responsible for their own section, as long as the heading is the same and the airspeed is the same.
The probability of a mid-air collision is almost non-existent."
All planes are flying in the same direction and at the same speed. In theory, a rear-end collision is never possible.
Even if one speed is faster and the other is slower, there is still a distance of more than 200 kilometers. The tower can easily adjust each batch of fighters.
Thinking of this, Bao Guanhua nodded slightly and agreed, "Then I'll do it according to your wishes. Everyone, no matter what, you must do your best to complete this glorious mission of assisting the local area to eliminate pests and save the people's property from fire and water!
"
"Complete the mission resolutely!"
Li Zhan and others made a splash.
At 20:05 p.m., eleven su-27sk and su-27ubk aircraft were divided into four batches and took off from Nanku Field Station at an interval of three minutes. The first batch was responsible for the nearest section, led by Li
There were only three fighters under the leadership of Zhan Zhan. Li Zhan needed to return to the field to replenish the liquid medicine twice, and he had to replenish fuel at the same time when replenishing the liquid medicine for the second time.
Completing the task within two hours is plenty of time for others, but for Li Zhan, time is very tight. In other words, whether the task can be completed in advance depends entirely on whether Li Zhan moves quickly or not.
All the fighter planes took off with full fuel and loads, so the entire Falcon Group was dressed up for the first trip. All seven pylons were equipped with sprayers, and the internal fuel tanks contained nearly ten tons of aviation fuel. Only a few fighters were missing.
That's the maximum takeoff weight.
Li Zhan could clearly feel that the fighter plane was very heavy. Even he had never flown it with its full load capacity. At its most exaggerated, it only had four air-to-surface missiles and two air-to-air missiles, and the weight was almost half of the liquid medicine.
When taking off, the fighter plane taxied for a full 700 meters before reaching the minimum speed allowed to pull up. Li Zhan only dared to pull up after gliding for almost 800 meters. He is usually as nimble as a su-
The 27sk moves slowly and clumsily like an old ox pulling a cart, and the joystick and two rudders are a bit heavy.
Don’t talk about flexibility when it’s full of fuel and full of mounts. The fact that it can fly normally like a fighter jet already shows that the power is very good. Li Zhan couldn’t help but think, what is the flexibility of the J-10 when it’s full of fuel and full of mounts?
How is it?
He shook his head and made up his mind to forget about the J-10. He turned his head to the right and looked at the sun in the west. At this time, it was already hidden behind the clouds. If it hadn't been for the hard climb to six thousand meters above sea level, Li Zhan would not have been able to
See its true colors.
Each batch of formations headed to their respective airspace. Li Zhan took two wingmen, Lin Fei and Chen Dianjun, to fly south to the starting point fifty kilometers away.
It is the first time for everyone to fly a fighter jet to spray pesticides, and they have not yet been able to fully digest it. What’s more, it is the famous Su-27 heavy fighter that represents the third generation of aircraft. Before boarding the plane, look under the wings and under the belly of the aircraft.
With a full load of sprinklers, most people have the same illusion - with so many auxiliary fuel tanks, can they fly directly to Washington? Guam is nothing!
As we started to descend, Chen Dianjun saw a small dragonfly when he looked down and said, "Good luck, there is a low-altitude, low-speed target below. It looks like a lucky five."
Li Zhan turned his head left and right and looked down, and easily saw a dark green Y-5 flying slowly over the farmland below. He could vaguely see water mist extending backwards, and it was probably spraying pesticides. At this time,
The only thin spot in the clouds is right between the sun and the line between the farmland below, so the visibility is very good, which is completely different from the situation dozens of kilometers away.
After confirming the direction, Li Zhan said, "Go past him and continue descending. Don't scare anyone."
Li Zhan took the lead and resumed level flight. After confirming that he had passed the Yinwu agricultural spraying aircraft directly below, he continued to descend to 150 altitude and turned westward.
The two pilots on the Yun-5 saw with their own eyes three huge fighter jets flying forward in a triangular formation while descending in altitude, and then turning to the right.
"This is the army's fighter jet! Su Liangqi! Hey, what kind of bombs are they carrying?" Pilot A said.
Pilot B said, "It looks like an auxiliary fuel tank. That's not right. Su Liangqi doesn't have an auxiliary fuel tank. That perverted aircraft can fly four thousand kilometers on internal fuel."
"It looks weird. It's so big and has strong wind resistance. What is it used for?" Pilot A was puzzled.
Pilot B joked, "It can't be the sprayer, hahaha!"
"Spray pesticides on Kaisu Liangqi, you can't imagine..."
Pilot A didn't say the last word. He and Pilot B froze at the same time, their mouths opened wide enough to fit an apple in.
But I saw the three su-27sk turned right and started to form a formation, and started spraying liquid at a height slightly higher than them...
