Chapter 310: Saturation Relay Spraying
No. 02 Su-27SK is full of giant pesticide sprayers that look like auxiliary fuel tanks, and seven giant pesticide sprayers can carry five tons of liquid medicine, which is enough to spray more than 160 acres of land according to the amount of 30 kilograms per mu, and about 220 kilometers can be operated with a width of 500 meters.
Therefore, Li Zhan misunderstood what Deputy Director Zhong meant, he only calculated the range of the fighter, but did not take into account the factor of liquid medicine. Deputy Director Zhong just wanted Li Zhan to have a more specific understanding of the operating distance, and mentioned that continuous spraying would take two round-trips.
In fact, not only do you have to fly at least six round-trips, but you also have to land no less than seven times to replenish the liquid.
Li Zhan was mentally prepared to fly for eight hours in a row.
What made him feel troubled was that Deputy Director Zhong proposed to spray after the sky had darkened. Because this type of pest likes darkness, it basically does not come out during the day.
Long-distance, low-altitude and low-speed flying at night is definitely a difficult flying subject. Li Zhan didn't care about resting, and repeatedly and carefully studied the terrain and landforms that the route had to pass. The 101st Brigade rarely flew here for low-altitude flight training, and Li Zhan's familiarity with the terrain and landforms here was far less than that of the Beiku Mountains.
just dropped a J-10A, he didn't dare to take it lightly, and repeatedly reminded Miao Yu to focus on checking the situation of the two planes, and once there was anything wrong, he would report to apply for a replacement of the plane.
Two hours before departure, Deputy Director Zhong came to Li Zhan, said the main points again, and then said, "Captain Li, I'm going to work hard for you tonight." After your end, our technicians will inspect the condition of the isolation zone overnight and strive to get the results before dawn. If I need to respray, I'll report it up right away. ”
Li Zhan smiled bitterly and agreed, "I promise to complete tonight's task!" ”
That's all he can say.
After eight hours of flight, he will be paralyzed even if he is beaten with iron, and he will not be able to come to the second eight hours tomorrow during the day.
Li Zhan asked, "Yes, since pests like darkness, will the supplementary spraying during the day tomorrow be effective?" ”
"Yes. It's just that spraying at night is the most effective. We are in a race against time, and we must open up the barrier in the shortest possible time, and we must see 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. There should be enough time, it's a big deal to delay it by an hour or even two hours, but still be able to complete the task ahead of schedule.
After deciding, Li Zhan said, "Director Zhong, I have a faster way." ”
Director Zhong was suddenly pleasantly surprised, his eyes lit up, and he asked excitedly, "What way?" ”
"Increase the number of aircraft on mission." Li Zhan said with a smile, "In order to save time, all the liquid medicine is packed in the sprayer. There are enough sprayers, all that's missing is planes, right? ”
Director Zhong said, "That's right, we do it at all costs, and the sprayer and the liquid medicine have double the redundancy. ”
Li Zhan said, "I can solve the problem of the aircraft, bring all the sprayers, and take the staged relay spraying in a saturated state, which can greatly reduce the time for opening up the isolation zone." According to my estimates, the 700-kilometer barrier could be completed in two hours. ”
It was shortened by six hours.
It is almost equivalent to saving thousands of acres of cotton fields.
"You can send more planes, can you?" Director Zhong asked excitedly.
Li Zhan nodded solemnly, "No problem at all!" If you agree with my plan, I will report it to my superiors immediately. ”
"Agreed! Agree! Captain Li, you've really helped us a lot! Six hours of time is equivalent to recovering the losses of hundreds of farmers! Director Zhong was so excited that tears appeared in his eyes.
It is difficult for people who have not experienced natural disasters to understand such feelings, and Director Zhong, who was born in a peasant family, is a technician who is on the front line when agricultural natural disasters arrive, and he knows too well how important it is to fight the disaster in the future and how much damage can be recovered.
Li Zhan did not delay the time and immediately asked the brigade for instructions and reported. After Xue Xiangdong received the report from the duty room, he immediately asked the head of the air force duty of the military region, and after obtaining permission, the Beiku combat training base sounded the alarm for emergency dispatch. All the fighters that can fly in the Eagle Falcon Brigade are all pulled, and the task of combat readiness duty is temporarily handed over to the Second Brigade.
Only 10 minutes later, the air division approved the plan of the 101 brigade, Xue Xiangdong gave an order, ten Su-27 fighters successively lifted off and transferred to the South Reservoir Station, and at the same time, two Army Aviation Mi-171s stationed at the North Warehouse Combat Training Base carried four maintenance crews to quickly transfer to the South Reservoir Station to participate in the support of the fighters. Shi Zezhong had already received the order, so the South Reservoir Station also began to pull, and all logistical support preparations must be made before the arrival of the transfer group.
In less than an hour, all the units were in place, and the Nankuchang station suddenly became lively, and it was a little crowded because of the eleven heavy fighters stationed there. It was only seven o'clock in the afternoon, at least an hour before it got dark.
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 a distance of less than 300 kilometers, and if it is a transfer battle of thousands of kilometers, how long will it take?
The maintenance support detachment was the last to arrive, and if the South Depot Station had the ability to support the Su-27, the transfer time would be reduced by half......
The fighters of the entire Eagle Falcon Brigade have been transferred to the Nankuchang Station, and Li Zhan is no longer the commander of the light pole.
The sprayers are all ready-made, made in full accordance with the pylons of the Su-27, including the circuits, all for this model. It took only one day to create a sprayer capable of spraying with Su-27 fighters from scratch. This kind of manufacturing potential is unparalleled.
As soon as the maintenance detachment arrived, it began to overhaul the fighters, then hung up the sprayers, and then carried out repeated overhauls. This preparation was completed a little faster than Li Zhan expected, and some time was regained.
The command team led by Bao Guanhua came with the maintenance detachment, stationed in the tower of the South Reservoir Station, and relied on the advantage of the nearest distance of the South Reservoir Station to direct the pesticide spraying operation nearby. Xue Xiangdong has to be on duty at the Beiku combat training base, and in the case of dispatching a large group of fighters to fight on the battlefield, he can only take charge of the battle, and no deputy position will be possible.
Whether it is the second division or the 300 division, if they are to form a flight brigade or above and go to Beiku for training, they will either be led by a military chief or a political commander, and there will be absolutely no third candidate. In addition, cross-regional flight training at or above the level of the flight brigade must be approved by the Supreme Command, and it is absolutely not possible to just file for the record.
It was the first time Li Zhan had seen Political Commissar Bao command a military operation, even if it was a flight training operation, it was very rare, at least Li Zhan had never seen it.
When he arrived at the tower, Bao Guanhua and the operational staff officers were analyzing several maps on the combat table with solemn expressions. There are aeronautical charts, crop distribution maps provided by the agricultural department, and even the largest one is a very clear satellite photo.
"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 have a big or small smile in front of Bao Guanhua, the whole brigade knew that the political commissar was a person who was not smiling and extremely disciplined and principled, to put it bluntly, he was not very easy to get along with and had rigid concepts. I don't like Commissar Bao very much, but what I am most afraid of is Commissar Bao, known as Commissar Bao.
Xue Cannon Bao Blackface soon became a famous golden partner in the Air Force Aviation Unit.
"This is the battle plan. We divided the 700-kilometer strip into three sections, each of which was 230 kilometers, and arranged for four fighters to work at the same time in each section, carpet spraying, and covering a two-kilometer-wide cotton field at one time. Director Zhong made it clear that the best effect is to minimize the operation error at the same time. Bao Guanhua briefly introduced the plan.
Li Zhan agreed with this method of warfare, and he raised a small question, "But the distance of the liquid medicine carried by each sortie is only 220 kilometers in theory. ”
Bao Guanhua said, "You take the first batch to carry out the nearest first stage, and immediately after completing the operation, you will return to the sea to replenish the liquid and then take off again as a reserve." The first section is only a few tens of kilometers away, and you will have at least six tons of jet fuel after you return to land, which is enough to go to any section for replenishment operations. ”
"Understood, commissar, I will resolutely complete the task!" Li Zhan straightened his back.
Bao Guanhua said solemnly, "According to the latest report from the Meteorological Observatory, the weather has turned cloudy, and the clouds are very thick, but the wind direction and strength of the low-altitude wind have not changed much. The main thing is the visibility problem. All fighters are flying at low altitudes between 150 and 200 meters, and avoiding collisions is the first priority during operations. ”
Li Zhan said with confidence, "Please rest assured that all the pilots of the Eagle Falcon Brigade have excellent results in air combat without altitude difference, and they are very good at low, medium and high altitudes, and there will be absolutely no collision accidents!" ”
"I suggest assigning height." Bao Guanhua frowned and said.
Li Zhan thought for a while and said, "The best spraying altitude is one hundred and fifty meters, and I plan to have all fighters operate at this altitude." Everyone is responsible for their own section, and the probability of an air collision with the same heading and airspeed is almost non-existent. ”
All the planes are flying in the same direction and at the same speed, and theoretically there is never a rear-end collision.
Even if one is faster and the other is slower, there is still a distance of more than 200 kilometers, and the tower can calmly adjust each fighter and each batch of fighters.
Thinking of this, Bao Guanhua nodded slightly and agreed, "Then do it according to your wishes." All in all, no matter what, we must make every effort to complete the glorious task of assisting the local authorities to eliminate pests and save the people's property from fire and water! ”
"Resolutely complete the task!"
Li Zhan and the others were loud.
At 20:05 p.m., eleven Su-27SKs and Su-27UBKs took off from the South Depot station in four batches at a speed of three minutes apart. The first group was responsible for the nearest first section, led by Li Zhan, and had only three fighters. Li Zhan needs to return to the field to replenish the potion twice, and he needs to replenish the fuel at the same time when he refills the potion for the second time.
Completing the task in two hours is plenty of time for others, but time is tight for Li Zhan. In other words, whether or not the task can be completed in advance depends on whether Li Zhan's actions are fast or not.
All the fighters took off with full fuel and loads, so the whole group of the Eagle Falcon Brigade traveled for the first time. All seven pylons were hung with sprayers, and the fuel tanks inside the aircraft were filled with nearly 10 tons of aviation fuel, which was just a few fighters short of reaching their maximum take-off weight.
Li Zhan could clearly feel that the fighter plane was very heavy, even he had never flown with a full load, and at the most exaggerated time, it was only four air-to-ground missiles and two air-to-air missiles, which weighed almost half of these liquids.
When it took off, it took 700 meters for the fighter to reach the minimum allowable pull-up, and Li Zhan only dared to pull it up when he had taxied for almost 800 meters. The Su-27SK, which is usually as agile as something, moves slowly and clumsily, like an old ox pulling a cart, and the joystick and two rudders are a little heavier.
Don't talk about any flexibility when you are fully fueled and loaded, and being able to fly normally like a fighter already means that the power is very good. Li Zhan couldn't help but think, what is the flexibility of the J-10 when it is fully fueled and loaded?
He shook his head and made up his mind to forget about the J-10, and tilted his head to the right to look at the sun in the west, at this time it was already hidden behind the clouds, if it hadn't climbed to a sea height of 6,000 meters just now, Li Zhan would not have seen its true face.
The formations of each batch went to the airspace of their respective sections, and Li Zhan took two wingmen, Lin Fei and Chen Dianjun, to fly south to the starting point 50 kilometers away.
It is the first time that everyone has encountered such a thing as spraying pesticides on fighter jets, and it has not been completely digested so far, not to mention that it is the famous Su-27 heavy fighter, a representative of the third generation aircraft. Before boarding, most people have the same delusion that there are full of sprinklers under the wings and belly of the aircraft, and most people have the same illusion - so many auxiliary fuel tanks can fly directly to Washington, right? Guam is a piece of!
When Chen Dianjun looked down, he saw a small dragonfly and said, "Good luck, there is a low-altitude and low-speed target below, which looks like Yunwu." ”
Li Zhan shook his head left and right to look down, and it was easy to see a dark green Yun-5 flying slowly over the farmland below, and he could vaguely see that there was a water mist extending backwards, and eighty percent was spraying pesticides. At this time, the only thin part of the cloud layer happened to be between the sun and the line of the farmland below, so the visibility was very good, and it was a world away from the situation dozens of kilometers away.
After confirming the direction, Li Zhan said, "Go past him and continue to descend to the height, don't scare people." ”
Li Zhan took the lead, and after resuming level flight, he confirmed that he had crossed the Yunwu Agricultural Spraying Plane directly below, and he continued to descend to an altitude of 15 and turned westward at the same time.
The two pilots on the Y-5 saw with their own eyes the three huge fighters flying forward in a triangular formation in front of them as they descended in altitude and then turned to the right.
"This is the fighter of the army! Su Erqi! Hey, what kind of bullet are they hanging? Pilot A said.
Pilot B said, "It looks like an auxiliary fuel tank, no, Su Liangqi doesn't have a auxiliary fuel tank, and that perverted plane can fly 4,000 kilometers with internal fuel." ”
"It's weird, it's so big, it's so strong, what is it for?" Pilot A was puzzled.
Pilot B joked, "It can't be a sprayer, hahaha!" ”
"Kaisu and Qiqi spray pesticides, you can figure out ......"
Pilot A didn't say the last word, he and Pilot B froze at the same time, their mouths wide open enough to fit an apple.
But seeing that the three Su-27SKs turned to the right, they began to pull out of formation and began to spray the liquid at a slightly higher height than them......
