Rebirth 1975: Tore up the call-back order at the beginning

After confirming the work plan, Zhou Yang and the others ignored the rest and threw themselves into intense work!

Since the Liaoshen Aircraft Factory only has two J-[-] fighters here, and time is tight!

For Zhou Yang and others, this means that any changes must be foolproof. After all, limited resources greatly reduce their chances of trial and error.

Fortunately, Zhou Yang has not only seen the J-2b fighter modified by the Zerghawk, but also the J-[-] fighter designed by ourselves. He knows very well that the key to upgrading the J-[-] fighter is to improve the front-end body layout of the fighter.

The J-8 adopts the aerodynamic layout form of nose air intake, large sweep angle, small aspect ratio, thin delta wing, lower flat tail, and double pelvic fins.

Although such a layout highlights the high-altitude and high-speed performance, increases the range, increases the rate of climb, and strengthens firepower, it meets the requirements of high-altitude combat, making this fighter compared with the J-[-], J-[-] and J-[-] fighters in terms of various performance indicators. Improve and improve.

However, such a layout also sacrificed part of the space of the fighter, making the original model of J-[-] lack of space for installing more advanced avionics equipment.

Therefore, Zhou Yang immediately redesigned part of the body of the original model according to the nose layout of the J-2 fighter in memory, and proposed the air intake on both sides, the aerodynamic layout of the flat tail and double pelvic fins under the delta wing.

At the same time, he also proposed that the fuselage of the fighter be made of an all-metal semi-monocoque fuselage to increase the strength of the fighter.

Afterwards, Gu Zhenhua led the J-[-] fighter design team to immediately demonstrate the plan proposed by Zhou Yang and conduct wind tunnel tests.

Since Zhou Yang's plan has been verified, there will naturally not be any problems in theoretical demonstration.

Although there is no large-scale wind tunnel available for testing due to limited conditions, and only models can be used for testing, the theoretical demonstration was quickly passed.

After passing the demonstration, Liaoshen Aircraft Factory immediately re-produced the nose according to the improved plan.

Due to the rush of time, the airport can only let engineers build the required parts by hand.

On September 9, after a week of overtime work, the nose part of the improved model of the J-8 fighter was finally built.

Subsequently, under the auspices of Zhou Yang, Gu Zhenhua and others, the new machine head finally replaced the original old-fashioned machine head.

After replacing the new nose, everyone felt that the modified model was more domineering.

However, the purpose of modifying the nose is not to make the fighter look better, but to increase more space and facilitate the installation of more advanced avionics systems.

The avionics system is very important for the performance of the fighter.

In all avionics systems, radar is the most important component, in addition to global positioning integrated navigation system, multi-function display system and integrated electronic countermeasure system and so on.

After the modification of the nose, it was the turn of Zheng Aiguo and others to play.

Then, with the efforts of Zheng Aiguo and others, the pulse Doppler radar brought from Babaoliang Village was installed on the No. [-] aircraft.

Finally, after working hard for so long, this advanced radar finally has a real place to live.

At this time, the time has come to September 9th, and it has been 20 days since Zhou Yang and others arrived at the Liaoshen Aircraft Factory.

To be honest, this time is much slower than Zhou Yang expected!

But Zhou Yang also knew that no one could be blamed for this, it was mainly because of unexpected incidents that delayed the progress of the work.

The sudden death of that person directly disrupted the research progress of the research team.

In addition to various mourning activities, more than ten days were delayed.

Fortunately, although this matter has a great impact, everyone knows that the dead have passed away, and the living must continue to live.

After a period of delay, the comrades in the working group devoted themselves to intense work again.

Finally, on September 9, the upgrade of the radar system of the fighter was completed!

Subsequently, Zhou Yang and Gu Zhenhua jointly reported the situation to the senior management of the Liaoshen Aircraft Factory and requested for the first test flight.

After the high-level discussion in the factory department, they agreed to their test flight request and set the test flight time on the morning of September 9rd!

.......

In the early morning of September 1976, 9, at one end of the test runway of the Liaoshen Aircraft Manufacturing Factory, a heroic fighter plane was parked there, waiting for the order to take off.

In the observation area on the side of the test flight field, hundreds of staff members in uniform gathered together excitedly, and everyone's eyes were fixed on this domineering fighter plane.

In the front row of the observation area, Zou Haiping, director of the Liaoshen Aircraft Factory, and a group of factory leaders were also discussing the fighter in front of them enthusiastically.

Although they often listened to the reports of Gu Zhenhua, Zhou Yang and others during this period, and knew that they had made great changes to the No. [-] aircraft, they did not expect that the appearance of the modified fighter plane would be so domineering.

More importantly, even people who don't understand technology can see that with such a change, the space in front of the fighter plane has increased significantly, and this solution is obviously better than their previous design.

For a while, everyone was full of expectations for this fighter!

At 9:[-] in the morning, as the test pilot entered the cockpit, the test flight work entered the countdown.

Then, under the order of Zou Haiping, the test pilot started the fighter plane!

With a huge roar, the fighter plane began to taxi quickly on the runway, and then the pilot pulled the stick to climb, and the fighter plane went straight into the blue sky.

After the fighter plane took off, everyone did not relax, and no one cheered. Everyone's heart was raised.

After all, the plane has changed so much, it is nothing to fly, and it has to be stable.

At this moment, the voice of the pilot came from the microphone of the control tower: "Report, the aircraft is at an altitude of 3000 and a speed of Mach 1.5. The flight is normal!"

After hearing the pilot's report, the staff at the scene were relieved, and immediately cheered.

At this moment, there was another loud engine sound in the air, and then the fighter plane lowered its altitude and circled smoothly and cheerfully.

Everyone was excited to see the fighter plane's vigorous and light movements. This shows that the fighter plane did not affect its flight because of the change in body design, and their improvement was successful.

At that moment, Zhou Yang immediately passed the control tower and asked the pilot to test the performance of the radar immediately!

Soon, the pilot's exclamation came from the tower side: "Report: The radar scanning range is plus or minus 65 degrees; the pitch is 8 lines... the detection range of the front hemisphere is 310 kilometers, and the detection range of the rear hemisphere (sideways) is 245 kilometers ..."

Hearing the voice from the tower microphone, everyone in the entire observation area was stunned!

Although not all the leaders and technicians present understand radar, they all know the basic parameters of the J-[-] fighter jet. In comparison, the data reported by the pilots can no longer be described as hanging.

The two are not comparable at all!

Such parameters not only easily achieved over-the-horizon detection and tracking, but even surpassed the functions of general early warning radars, throwing the radar they were equipped with ten blocks away!

After replacing the radar brought by Zhou Yang and others, the J-[-] fighter is no longer inferior to any fighter in the world in terms of detection and tracking capabilities, not firepower.

Even against the third-generation fighters of the Bear Alliance and the Javelin, they are not inferior in this regard.

If the engine and weapon system problems are solved, this fighter may indeed become a true third-generation fighter as Zhou Yang said.

Thinking of this, everyone including Zou Haiping became excited.

After a short period of silence on the field, the staff on the scene soon burst into cheers again.

In an instant, the entire test flight field burst into thunderous applause, which lasted for a long time!
