Chapter 816 Time to turn around
To fight against the pd detection mode of an/apy-1, it is not enough to rely solely on the radar stealth ability of MiG-29n.
Regarding this issue, Long Yun has calculated and tested it many times before. He estimated that the distance between himself and his partner G-29n was discovered by "Wanglou" is about 100 kilometers. This distance is still a bit far for the MiG aircraft carrying the R-27ep to launch a raid: if it is discovered by the early warning aircraft and continues to advance, they will become very eye-catching on the radar display of "Wanglou".
Once the enemy is aware of it and takes countermeasures, two MiG aircraft with worrying combat power are used to deal with the NATO interceptor fighter jets that are swarming, there is no possibility of completing the mission.
So now, in the cockpit with a good vision of the stealth fighter, Long Yun has to complete a mathematical problem with the data analysis function of the radio detection system. He needs to judge the target's movement trajectory and flight status before he can decide whether to continue approaching and launch a missile sneak attack.
According to the original triangular ranging method, combined with the e-3a "Wanglou" air patrol area provided by the KGB, Longyun calibrated the target position with a limited automation detection system and determined that the US early warning aircraft hovering in the western Turkish airspace at this time was about 130 kilometers away. Moreover, judging from the changing trend of the target's position, this "Wanglou" is flying along a scheduled route in the east-west direction, and the heading angle with their group of MiG aircraft is about 70 degrees, which is a pretty good tactical condition.
As we all know, when the Doppler filtering mode is turned on to complete the target search, the radar's interceptor ability of the fighter is not only affected by the target rcs, but also by the relative speed between the two.
Theoretically, the distance between radar detection head-on and targets is the farthest. The detection capability of targets that maintain the same speed vector is almost zero; this principle is roughly applicable to an/apy-1 installed in the e-3a "Wanglou". Now the Longyun dual-machine is equal to approaching from the front side of the early warning aircraft. This is a situation where you neither suffer any loss nor benefit from it. You should allow the mystery to
-29n is close to one hundred kilometers without being discovered.
But even so, in the face of the "Wanglou" early warning aircraft that is tens of kilometers away, can we directly launch the R-27ep to carry out an attack?
Long Yun hoped that this would be the case, but now he was under the integrated hatch and looked at the sky around him vigilantly. He thought that he and his partner had good luck so far, but as a normal pilot, not a Kanyu team member who committed suicide attacks, he had to make the sneak attack unknown as much as possible, and neither the target nor the escort aircraft could be noticed.
To do this, his actions must be cautious, but his decisions need to be more decisive, because now the two fans have left the Soviet GCI guidance system, and no one can make decisions for him; continue to fly the fighter planes to approach prey, Long Yun keeps the landline flying smoothly without any additional actions, he needs to get closer now and wait for the upcoming opportunity.
If you can encounter a situation like "early warning aircraft turns around", although it may not be as you wish in time and place, it is also good to try to make use of it.
If you want to keep wandering over the war zone, it is impossible for the e-3a "Watch Tower" to keep sailing in a straight line. You must fly horizontally for a distance and fly backwards. The US Air Force has a series of standard tactical processes. For example, it is very common to simply turn back directly at the navigation point.
With a detailed understanding of these strategies, Long Yun is waiting for such an opportunity.
In the short time when the early warning aircraft turned around and returned, the an/apy-1 radar on the "Wanglou" will remain in operation, but will basically lose the search ability due to coordinate system transformation and the speed vector interference of the PDF mode. It can only be restored after the carrier aircraft resumes its stable flight state.
Such a little system failure time will not become a loophole in conventional operations, and Long Yun did not expect to rely solely on this gap to successfully attack; however, at present, the MiG dual-machine aircraft must wait patiently for the arrival of this moment, because the launched R-27ep missile cannot frequently correct the ballistic, otherwise the range will be greatly reduced, so they must wait for the e-3a to complete the turn, be sure that the track will not be adjusted for a period of time, so that the parameters can be set safely and the missile will be launched to make a fatal blow.
But when will they start turning around and flying according to the actions of the Americans?
The internal fuel in the driving was much higher than the prototype, but the fuel consumption rate was even more amazing. The Longyun's two-wheeled aircraft had already flew about 400 kilometers away from the Bugas base. Their next actions must always pay attention to fuel consumption, otherwise they will not be able to leave necessary fuel for the return flight. This kind of careful calculation and fighting experience of waiting for the enemy to hit the gun is a difficult to endure for the pilot. Fortunately, Longyun's psychological quality is quite good. He has been paying attention to the data changes in the signal intercept system and inferring from it whether the e-3a "Wanglou" has entered the return route.
When flying a radar stealth fighter, approaching the prey and waiting for an opportunity to move, you should also be careful not to become the target of nearby NATO fighter jets. When driving a miracle g-29n passes through the gloomy sky, Long Yun can feel sweating in his palms.
Compared with the previous air battle where he was happy and cheerful, his actions are now more like an assassin sneaking in the dark night, looking out the window, waiting for the most suitable phone to come out. Not only that, the oil storage of the landline is also decreasing. Once the oil storage is stored, they must give up the operation and return. Although there is still a chance later, this means that the feasibility of the raid is not high, which is not exciting news for the Design Bureau.
So now he really wants to score the first record and win, but will the Americans cooperate well?
As if in response to Long Yun's expectations, just as he was meditating out of thin air, the display of the radio detection system changed. The bright line representing the s-band radiation signal drifted on the screen, and there was some deviation from the target direction detected before. At this time, although the specific distance number was not known, Long Yun could immediately determine that the "Wanglou" in the sky ahead had entered the turn-around route and would soon turn to the reverse flight.
Without further ado, the opportunity is now!
Seeing that the enemy plane was about to turn around and return, Long Yun immediately started to calculate the target distance. It was not easy to use passive signal intercepting equipment to do this. But now he is planning to use r-27ep, an over-visual range missile with a theoretical range of 75,000 meters, but the target looks ignorant. Therefore, as long as the target is guaranteed to be within the missile attack envelope, there can be a considerable probability of killing.
He went deep into the enemy country to carry out assassination missions, even the mysterious G-29n who drove the radar invisible was worried. The rwr alarm sounded in the cockpit from time to time, but it did not interfere with Long Yun's judgment at all.
After a rough estimate, the e-3a should have completed its turn, but it is still far from flying enough to stay away. Then the next "Watch Tower" must maintain its heading reverse flight and continue to work on the side of the war zone; the target trajectory of the triangular method is also basically determined, the distance between the enemy and us is about 80 kilometers, and the tail chase range exceeds the r-27ep!
Yes, since the target turned eastward, it had already escaped from the attack envelope of the R-27ep missile, but it also weakened the radar's detection ability of the two G-29ns, because the speed vector synthesis results of the enemy and us have changed; it was confirmed that the "prey" had turned around, Long Yun immediately swayed the wingman and signaled his wingman to pay attention to his actions. The two MiG aircraft, one in front and one behind, slightly pressed the slope and turned sideways, and entered the encirclement route of catching up with the early warning aircraft.
In the sky, the engine thrust is fully opened, and the MiG-29n with increased force overcomes atmospheric resistance and accelerates forward. The auxiliary air intake is greedily absorbing air. The two rd-33 engines are trying hard to exert the maximum thrust under adverse operating conditions, allowing the light gray stealth fighter to gradually accelerate to Mach 0:7, and at the same time climbing all the way into the pursuit route.
Faced with the E-3a "Looking Tower" whose cruising speed has been maintained at hundreds of knots, it is not easy for the G-29n who has closed the main air intake to catch up. However, the two aircraft of Longyun naturally cannot keep a close eye on the target position like hunting dogs chasing rabbits, and draw a trajectory in the air that is far and far away. Instead, plan a trajectory intersection in advance, and take a 45-degree pursuit angle to ensure that the trajectory after launch is basically in a straight line to obtain the maximum tail chase range as possible.
As the fighter jets penetrated through the clouds and accelerated forward, a large area of continuous clouds were thrown away from the distance. The MiG aircraft that rushed out of the gray sky gradually shortened the distance from the target. Long Yun in the cockpit looked almost discovered the outline of the "Looking Tower" in the sky: in the cloudless clear sky with a height of thousands of meters, the Boeing 707 body with a black radar disk looked quite obvious. From the analysis of "clearly visible", he knew that his general calculation was basically reliable. Now the distance between the enemy aircraft has reached within 30 kilometers, and the nearby sky is also-
Sure enough, there is no guard around the early warning aircraft!
