Chapter 644: Take off, too good!

The timetable promised by He Ming was by no means an empty lie.

It did take them only three days to complete the last piece of the puzzle on the No. 1010 technology verification fuselage.

After all, No. 1010 is a highly classified verification aircraft, so after completing all in-factory testing processes, there is no traditional red flower and ribbon link.

Everyone, including Chang Haonan, just held a brief ceremony in the assembly workshop to celebrate the J-11WS's achievement and preparations for its first flight.

"I never dreamed before that it only took about a year and a half from the time when the first large-component J-11 rolled off the assembly line to when the J-11 was equipped with a domestic engine..."

When everyone applauded, Luo Shida, standing next to He Ming, said with emotion.

It was a bit like talking to himself, but several people nearby could still hear it.

As a retired comrade, the latter was initially rehired to be responsible for the translation and format conversion of some Russian drawings. It was expected that the job would be over after a few months.

But which veteran cadre can withstand such a test as a domestic heavy fighter?

A few months later, Luo Shida couldn't leave.

Then, he was rehired until now...

"It's not just domestically produced."

Although He Ming's main business is machinery manufacturing and he did not have the opportunity to participate in the design review and detailed plan design the year before last, he had participated in the China Aviation Development Industry Conference as a specially invited technician the year before last, and the J-11WS technology The person in charge of the production of the verification machine still knows something about the turbofan 10:

"I have talked with engineers from the 606 Institute and Liming Factory before. The technical solution of this turbofan 10 is not only completely different from the American CFM56 core machine, but in my impression, no other country has used a similar design. It is completely different." It is made by our own hands, which is equivalent to making something from scratch. This is the most difficult part..."

"Ok?"

Luo Shida was re-employed. Although his status was not low, he had no official status after all. He almost deliberately rarely asked about things other than Project 10. At present, there were not many updates on the knowledge of Turbofan , except for some that almost everyone knew. Apart from the rumors, it is still basically the time before retirement.

Therefore, I was immediately stunned after hearing this:

"I heard that this project was re-established the year before last. Lao Zhang took the initiative to report that he was going to build a naval gas turbine, but it took two years to produce the product... …The overall technical plan should not change much, right?”

"Um……"

He Ming knew that the other party's analysis was actually very reasonable, but the problem was that some people were unreasonable at all, and it was hard to explain for a while. In addition, the ceremony was about to end, so he had to make a long story short:

"In short, the current turbofan 10 has basically no technical relationship with the previous turbofan 10, except that they both use the same equipment number."

After explaining, perhaps because he was worried that he was not convincing enough, he added another sentence:

"Mr. Luo, if you think about it, if you still use the CFM56 core machine, how can it be possible to achieve a thrust-to-weight ratio of 9? So it must be brand new..."

Luo Shida just couldn't update information fast enough because he was retired, but his thinking ability was still fine, so he realized that He Ming was right after a quick thought.

But compared to using CFM56 as the core machine to achieve a thrust-to-weight ratio of 9, he still feels that the possibility of coming up with a new engine in two years is smaller.

Therefore, after these two ideas collided, Luo Shida came to a conclusion——

The superiors obviously worked on two projects, one overt and one undercover. The turbofan 10 on the surface was a replica of the F110 engine, and it was stumbling along the way. This was a way to hide the incompetence and make others relax their vigilance, while the secret project was to start from scratch. In the beginning, under the cover of the former, he finally succeeded in cultivation, and the year before last, he returned to the sight of ordinary people by borrowing corpses and resurrecting souls...

Simply perfect!

Thinking of this, Luo Shida raised his head again and looked at the back of Chang Haonan standing in the middle of the crowd.

When he was invited out of the mountain, Project 83 had already been finalized, so he had never met the latter directly. He had only heard some mysterious rumors.

I used to wonder how one person could be responsible for so many projects at the same time, so I always thought he was the kind of person who uses his strong background to gain fame and reputation.

But if the facts are really as he thought just now, then this kind of plan to steal the sky and change the sun may have to be thought up by the other party. It seems that he is really a master...

In short, although the analysis was wrong, in the end, due to the collision of errors, the correct conclusion was reached...

……

At this time, Chang Haonan also took a step forward, came to the center of the stage, and cleared his throat:

"I announce that the J-11WS technology verification aircraft has officially completed its final assembly and is ready to leave the factory!"

As he finished speaking, an aircraft tractor that had already fixed the tow bar to the front wheel of the aircraft started and slowly drove towards the door of the workshop.

Compared with a few days ago, this aircraft has now been painted with the same painting as the Air Force Su-27SK/J-11, and the aircraft number has been deliberately concealed to avoid any clues being seen during frequent flight tests. .

After all, although the camera is pointed at the airport and life is walked into a prison cell, in terms of operation, there are so many places where you can use a telephoto lens to capture the takeoff and landing of the plane, and it is impossible to completely capture it.

Considering that the technology of the J-11 is relatively mature, there is no need for the same aircraft to conduct continuous test flights. Moreover, the original yellow paint is quite eye-catching and can be seen clearly from a distance.

If you show up every day, someone will soon find out the clues.

After changing the paint, it looks exactly the same as a mass-produced model that is about to be delivered to the troops. As for the difference in the engine tail nozzle, it is impossible to hide it, but as long as the take-off and landing process uses a relatively steep route, it is also possible. Not that easy to spot.

It can be regarded as relieving worries in this regard.

The ground crew who had already prepared outside set up the boarding ladder on the left side of the nose of the aircraft. The test pilot, who had also completed preparations early, saluted Chang Haonan and others, and then stepped on the ladder one after another to enter the cockpit.

The aircraft and flight control itself are mature technologies, only one of the engines is brand new, and all unmanned project tests have been completed before leaving the factory.

So, the next step is to prepare directly for the first flight.

Since the J-11 is not equipped with an auxiliary power unit, the engine still needs an external power supply vehicle and air source vehicle to serve it from cold to start.

After all, it is a new machine, and it takes half an hour to complete a set of procedures.

Also taking advantage of this time, Chang Haonan and his team moved from the assembly workshop to the flight command center inside the tower.

"Call the command center on 1010. The plane has started and is taxiing. It is about to enter the runway. Please request instructions."

The thrust of the engines on both sides of this aircraft is different, and the flight subjects are also very different from those of a normal prototype. Once you get used to it, it will be awkward to fly a normal aircraft again.

Therefore, Fu Guoxiang, the chief test pilot stationed at Factory 112, was not selected to participate in the aerial test of the Turbofan 10 this time, but continued to perform the factory test flight missions of the F14 and J-11.

Sitting in the cabin now is another test pilot Song Shangcai.

The J-11WS is modified from a two-seat aircraft, but the rear seat is retained just to improve mission compatibility.

There was no need for a second pilot today.

"Stop in the take-off position first, keep braking, and prepare for a round of pre-take-off testing."

It was also the first time for the flight commander to perform a special aviation engine test flight mission, so he had a thick flow chart next to him and was issuing instructions according to the above steps.

Although he was confident that he had memorized the contents backwards and forwards, the rules were the rules, and he could not increase the risk of making mistakes just to show off his skills.

In the cabin on the other side, Song Shangcai stopped the plane steadily at the end of the runway according to the instructions just transmitted by the radio. He then pulled up the brake lever and gradually pushed the throttle forward from idle, staying at several specific points in the middle. Observe the situation from your position.

After all, this runway does not have special wheel blocks like an aircraft carrier, and the braking force that the aircraft itself can provide is limited.

If you brake the car on the runway and use afterburner, the huge thrust can directly change rolling friction into sliding friction, and the pair of main wheels will be useless.

So I can only open it about half way and give it a try.

After all, the engine ground test had already been done in the factory, and now it was just a precaution and to let him get familiar with the slightly awkward characteristics of this aircraft.

With the gentle movement of Song Shangcai's left hand, the pointers of the two tachometers on the left and right rotated clockwise at the same time.

However, the engine speed on the left increases significantly more quickly, and the last position of the pointer is further to the left.

Even sitting in the cabin, he could already feel that the entire plane was preparing to take off like an arrow.

"Report No. 1010, the engine speed remains stable, and the response of the test engine is slightly faster."

Song Shangcai's voice sounded again:

"Request takeoff."

After a few minutes of smooth operation, he also gained a lot of confidence in this special verification machine——

No matter how good a pilot is or how thorough his pre-flight preparations are, he will definitely fly more carefully when he first gets a new aircraft.

After your confidence and proficiency gradually increase, you can gradually explore the ultimate performance of the aircraft.

"Received, permission to take off"

Almost at the same time as the commander issued the order, Song Shangcai, who was almost impatient in the cockpit, released the brake handle, then pushed the throttle directly to the "afterburner" position, and at the same time moved his right hand slightly to the left.

Standing in front of the floor-to-ceiling window of the tower, Chang Haonan could see the No. 1010 aircraft dragging two eye-catching tail flames, one purple and one blue, across the runway in front of him without even using a telescope.

After just ten seconds, with the slight rotation of the horizontal tail, the aircraft raised its head lightly.

Lift off the ground and take off!
