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.
No. 1010 is, after all, a highly classified verification machine, 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 preparation for its first flight.
"I never dreamed before that it only took about a year and a half from the first large-component assembly of the J-11 rolling off the assembly line to the installation of a domestic engine on the J-11..."
Everyone During the applause, Luo Shida, standing next to He Ming, said with emotion.
It seemed like he was 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.
After that, he was re-employed until now...
“It’s not just domestically produced.”
Although He Ming’s main business is machinery manufacturing, he had no chance to participate in the year before last Design review and detailed plan design, but after all, I participated in the China Aviation Industry Conference as a specially invited technician the year before last, and I was also the person in charge of the production of the J-11WS technology demonstrator, so I still have some concerns about the turbofan 10. What I learned:
“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 also in my impression. No other country has used a similar design. It is completely made by our own hands, which is equivalent to starting from scratch. This is the most difficult part..."
"Huh?"
Luo Shida was re-employed. Although his status was not low, he did not have an official status after all. He almost deliberately did not ask about things other than Project 11. At present, he was concerned about the turbofan 10. There are not many cognitive updates. Except for some rumors that are almost universally known, they are generally still at the time before retirement.
So after hearing this, I was immediately stunned:
“I heard that this project was re-established the year before last, and Lao Zhang took the initiative to report it and said that he would do it. The ship-use gas turbine is coming, but it only takes two years to produce the product... The overall technical plan should not change much, right?"
"Well..."
He Ming knew that the other party's analysis was actually very reasonable, but the problem was that some people were not reasonable at all, and it was not easy 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 it, I may be worried that it is not convincing enough. He also added:
" Mr. Luo, 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 engine 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.
So, after these two ideas collided, Luo Shida came to a conclusion-
The superiors obviously had two projects, one bright and one dark. The Turbofan 10 is a replica of the F110 engine, and it has been stumbling along the way. It uses this method to hide its incompetence and make others relax their vigilance. The secret project is to start from scratch and start from scratch. Under the cover of the former, it has finally been completed, and it was passed the year before last. He borrowed a corpse and brought it back to ordinary people's sight...
It's 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 as he thought just now, then this kind of plan to change the sky and change the sun may have to be thought up by the other party. It seems to be a real expert...
In short, although after some analysis, the donkey The words were wrong, but in the end, due to the collision of errors, they came to the correct conclusion...
...
At this time, Chang Haonan just took a step forward, came to the front position in the middle 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!"< br>
As his voice fell, 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 hidden to avoid being confused during frequent flight tests. Someone who is interested can see some clues.
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 J-11's technology is relatively mature, there is absolutely no need for the same aircraft to conduct continuous test flights, and the original yellow paint is quite eye-catching and can be seen clearly from a distance.
If you show up every day, people 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 really impossible to hide it, but as long as the relative use is used during takeoff and landing, Steeper routes are not so 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 also completed preparations early saluted Chang Haonan and others. Then one after another stepped on the ladder 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 directly prepare 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 an 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 period, Chang Haonan and his team moved from the assembly workshop to the flight control center inside the tower.
"Call the command center on 1010. The aircraft has started and is taxiing. It is about to enter the runway. Please request instructions."
The engine thrust on both sides of this aircraft is different, and the flight subjects are also very different from the normal prototype aircraft. Once you get started, Once you get used to it, it would be awkward to go back and fly a normal plane.
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 at the take-off position first, keep braking, and prepare for a round of pre-takeoff tests."
This is also the first time for the flight commander to perform a specialized aviation engine test flight mission, so he placed the He was holding a thick flow chart 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 it was impossible to 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 in accordance with the instructions just transmitted over the radio, then pulled up the brake lever and gradually pushed the throttle forward from idle, with some interruptions in between. Stay at several specific locations to observe the situation.
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 ground test of the engine has already been done in the factory. Now it is just a precaution and to let him get familiar with the slightly awkward characteristics of this aircraft.
With the gentle movements of Song Shangcai's left hand, the pointers of the two tachometers on the left and right turned 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 to take off."
After a few minutes of smooth operation, he also gained a lot of confidence in this special verification aircraft -
No matter how good the pilot is, or how thorough the pre-flight preparations are, he will not be able to fly a new aircraft until he gets it. When flying, they will definitely fly more carefully.
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, and then pushed the throttle directly to " "Afterburner" position, and at the same time, the right hand brings the pole position 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!
