First of all, there is actually no target that looks tall on the ground, that is, a simple cement stone platform is built in an empty mud shooting range, imitating a cement building, and there are really no more others, but it is this simple test target that imitates the most common target of modern aviation in ground attack to the greatest extent, and naturally it can play the best test role.

In the distance, the Yun-7 aircraft flew slowly, the huge propeller stirred the air flow that was calm a moment ago, seeing that the plane was getting closer and closer to the shooting range, at this time the crew on the plane also entered the final preparation and busy, the whole set of photoelectric targeting system in the design is used in the J-18, and the J-18 is operated by the pilot alone to complete the ground attack mission, which requires the whole system to have a high level of automation.

Therefore, a series of ground target searches, laser designation, and bomb drops in this test were all completed by one person, which is also a hard indicator in the design of the whole system: human-computer interaction and automation.

The airborne radar installed on the Yun-7 does not have the ability of topographic mapping, so when the laser targeting system performs a ground attack, it is impossible to obtain real-time images of the ground through the map mapd by the radar, and at this time, it is necessary to use another powerful function of the photoelectric targeting system, the terrain tracking radar and the forward-looking infrared sensor integrated on the infrared navigation system to intervene.

At this time, their role is not to provide flight navigation, but to use the powerful infrared search and imaging function, so as to quickly map the thermal infrared images composed of different heat sources on the ground, and then through the rapid processing of the system, it is the ground infrared data that can be used for the pilot's reference.

At this time, the image obtained has actually included the infrared image of the cement stone platform on the ground, and the operator continuously adjusts the position of the cement stone platform displayed on the display, up, down, left and right adjustment, anyway, it is to let the cement stone platform be displayed in the middle position of the display as much as possible, and the graphics can also be magnified according to the needs of the task.

After a simple processing procedure, the image on the display is the clearest and most suitable ground concrete platform, and then it is time to move on to the next stage: laser aiming indication.

After starting the laser locator, the cross crosshair will appear in the middle of the display, manually adjust the angle of view to press the crosshair to the center of the cement stone platform, when the system prompts to complete the laser aiming positioning, and then lock the cross crosshair on the current target point, although the aircraft is still moving in the air, but the laser locator will continue to adjust its angle with the movement of the aircraft to ensure the continuous locking of the target.

In fact, by this time, all the target search and aiming work had been completed, and the testers opened their mouths to talk to the ground command center, and Yang Hui had already watched a series of search operations in real time through the airborne air-ground data sharing system on the Yun-7 in the command center, and heard the operators on the plane request permission to drop bombs.

He calmly issued an order to Mai: "Bomb dropping is allowed!" ”

With the arrival of the ground authorization bomb delivery command, the operator immediately pressed the bomb drop button, and the 7721 laser-guided bomb mounted under the wings of the Yun-7 aircraft fell lightly, and according to the instructions of the laser positioning data, the bomb flew accurately to the ground target along the designated flight path under the guidance of the wind-marker seeker.

About a few dozen seconds later, Yang Hui and his entourage, who were far away on the periphery of the shooting range, also heard a dull sound, although this time the target missile was not filled with a warhead, it was a test bomb that would not explode, but the 500kg heavy object dropped at a height of thousands of meters smashed on the hardened cement, if there was no sound, it would be a strange thing.

"The bomb has landed, and you can return home."

After giving the air test plane a return order, Yang Hui couldn't wait to go to the scene to see the hit results of the bomb, so he beckoned everyone at the shooting range to rush to the predetermined bomb point, at this time the Jeep 212 did not have any overload problem, after sitting on the person, the driver stepped on the accelerator and went to the inside of the shooting range like a wild bison, along the way on the dirt road to set off a burst of dust, walking behind the car will naturally suffer, After all, the 212 is still a convertible design.

Compared with the slow motion of Yang Hui and others on the ground, it is much easier to get the test results on the test machine in the sky, and the real-time infrared image is updated to show that there has been a conspicuous point infrared heat source on the cement stone platform on the ground, which is obviously a high-heat infrared source after the high-speed collision and friction between the bomb and the cement stone platform just now.

According to the knowledge that the operator himself knows, he has already come to a conclusion in his heart: "The effect is good, although it did not hit the center, but the preliminary assessment should be that it hit the accuracy range of the 7721 bomb, which proves that our airborne search and sighting system has achieved the expected effect, so let's all return!" ”

At this time, the weapon operator finally put his mind at ease, took off the equipment on his body, and planned to stand up and move, and just after standing up, several other accompanying staff members rushed over to look at the thermal infrared photos that had been fixed on the monitor, and saw that it was indeed an accurate target on the ground.

After confirming the situation again and again, someone immediately went to the cockpit in front to inform the flight crew of Yun-7, no matter how this is also the crew who performed the test mission together, and everyone should have fun together when the mission is successful, and then the crew will return happily together.

On the ground, led by Yang Hui, the group is constantly going deep into the interior of the shooting range, and the cement stone platform can already be seen from a distance, and the test bomb will not explode, so it seems that everything is still well preserved until it is getting closer and closer.....

As soon as the car here stopped, Yang Hui jumped out of the car as soon as possible, and Yang Yue in the back also followed, and a total of eight people walked to the cement stone platform together.

The most conspicuous thing is a large hole four meters away from the center of the demarcated bomb landing site, from the outside it is definitely impossible to see the target bomb that has penetrated deep into the stone platform, the only thing that can be seen is the crack at the hole that extends to all sides, and there are a few pieces of detached missile wings next to it, but they are also deformed by the violent impact.

After signaling the on-site investigation and evidence collection personnel to hurry forward, and after taking pictures of the outside of the bullet hole, Yang Hui approached the hole entrance, and saw the target missile inserted in the sand below through the hole: "Judging from this angle of incidence, the target missile attacked the top of the cement platform vertically, which proves that the seeker did receive the laser aiming and positioning data, so this test was basically successful." ”

After probably giving the conclusion, he stood up and stepped aside, and the other evaluators also stepped forward to watch and record one by one, and some of the staff were ready to enter the inside of the cement stone platform for testing, after all, the cement stone platform was built according to the design of a house, and its interior was empty, so that after entering, you could get close to the target bomb inserted in the ground.

Yang Hui didn't plan to go in and join in the fun, and now it is roughly certain that the test work was successful, and it is enough to have this, at least the most important ground precision attack capability of the J-18 is roughly different from worry.

Seeing Yang Yue coming over, she also praised with a smile: "My wife is still capable, this should be the first chief engineer to complete the 18 supporting subsystems, and there is no exact news about other radars, engines, and electronic warfare systems, which makes people feel that all kinds of pressure are huge, and it is only today that there is good news." Let's go, we have to get off work on time today, and I'll cook for you when we get home! (To be continued.) )
