It’s already getting cold in Shengjing in October.
Most of the pedestrians on the street wore thick winter coats.
At this time, various types of down jackets had not yet become popular, and of course most people did not have that much money to buy down jackets.
Most of them still wore thick and warm military coats, and the few who got rich first wore fur coats.
At the military airport in the cold wind, a Su-27 painted in sky blue was quietly waiting on the tarmac.
The people surrounding it did not feel cold in their hearts because of the cold weather. It could even be said that everyone's hearts were like a blazing fire.
Except for Zhang Xingyang, who was specially invited to watch the first trial flight of WS-10, most of the people present were old people who had worked hard for the WS-10 project for many years.
Everyone sees that the results they have worked hard for many years are finally going to face the actual test, just like their own children are about to enter the examination room.
While I was happy, I was also very nervous.
The pilot of this Su-27 equipped with a domestically produced WS-10 engine was Lei Yong, a special pilot from the Air Force Test Flight Team.
Previously, Lei Yong had been training for the test flight of the domestic third-generation J-10 aircraft. Let him conduct the first flight of the WS-10, and there were also considerations in preparing for the test flight of the J-10.
"Major Lei, is this flight test safe?"
Zhang Zhengjiang asked him nervously before the flight test officially started.
It’s no wonder that Zhang Zhengjiang is nervous. This test flight is related to the future direction of the WS-10 project.
If the WS-10 engine really performs poorly in test flights, then the higher authorities will definitely make up their minds to introduce the AL-31F engine from Damao's family in the north.
By then, even if the WS-10 project team is not cancelled, the level of attention it will receive will definitely be greatly reduced.
"Comrade Chief, promise to complete the mission at any cost!"
Lei Yong did not directly answer Zhang Zhengjiang's question, but gave his own answer from his own perspective.
Everyone present also knew what this answer meant.
If any accident occurs while the aircraft is in flight, the other party will do its best to complete the flight test.
Even if it means giving your own life!
Seeing the test pilot's determination, Zhang Zhengjiang said nothing more, but gave a military salute:
"Thanks a lot!"
The aircraft tow truck slowly towed the Su-27 carrying the hopes of everyone present out of the apron.
After all preparations were completed, Lei Yong, who was already sitting in the cockpit, raised his thumb outside.
With the tower giving instructions to take off.
The WS-10 engine at the tail of the Su-27 sprayed orange flames. As the aircraft slowly taxied, the tail flames gradually turned blue again.
This means that the engine temperature is rising and is about to reach its operating temperature.
Generally speaking, without afterburner, the takeoff and rolling distance of a Su-27 fighter jet using the AL-31F engine is about 500 meters.
The current WS-10 engine has a thrust of 130KN, while Maozi’s AL-31F has a thrust of 135KN.
Therefore, after replacing the WS-10 engine, the thrust of the Su-27 engine has decreased.
The corresponding land sliding distance is also slightly longer.
After gliding a distance of 600 meters, Lei Yong drove the Su-27 and took off from the airport.
Like a war eagle about to attack high into the sky, soaring straight into the sky.
The first test flight did not involve any fancy operations. Lei Yong just flew the Su-27 fighter jet twice in the sky. The absence of any problems meant that the flight test was essentially successful.
However, it seemed that he only flew two laps. Lei Yong was not very satisfied and asked the command center to fly two more laps.
"Command center, request for two more flights."
During the previous flight, the WS-10 did not show any problems, so Zhang Zhengjiang, as the commander on the scene, agreed to the test pilot's request without hesitation.
The Su-27, after flying two circles in the sky like a war eagle, completed the entire test flight process.
As the pilot, Lei Yong also wanted to do a fancy job for everyone, performing the Cobra maneuver that made the Su-27 famous in the first battle.
Everyone present also wanted to see what the domestic engine could do, so they all looked at Zhang Zhengjiang in the command center.
As the person in charge of the entire test flight, Zhang Zhengjiang naturally wanted to see what the WS-10 could do.
So he agreed to Lei Yong's request.
After the Su-27 fighter circled in the air for a while, Lei Yong kept the speed of the fighter at about 420km/h, and then pulled the stick back to tilt the nose of the fighter upward 120 degrees.
So the sky-blue fighter jet had its tail in front and its nose in the back. The entire fighter jet seemed to be leaning backwards.
At this time, Lei Yong continued to increase thrust to press the Su-27 fighter's nose, causing the fighter to return to its original level flight state.
Seeing Lei Yong complete this climactic and difficult work that shocked the world at the air show just a few years ago.
The people in the command center couldn't help but applaud.
Zhang Zhengjiang, as the general person in charge, was no exception. He went through the fault and said to the people around him:
"We made it!"
"We finally have a high-thrust military engine belonging to the people of the Dragon Kingdom!"
"From now on we don't have to look at the faces of those foreigners!"
As an old man over fifty years old, Zhang Zhengjiang has always experienced an era when domestic engine technology was inferior to others.
This is why he was so excited after seeing the Su-27 perform the Cobra maneuver.
He had been waiting for this day for too long.
As for Zhang Xingyang, who was standing behind him, he was also a little emotional.
Only by truly coming into contact with this era can we feel the pressure everyone felt at this time when facing foreign military blackmail.
Zhang Xingyang thought as he looked at the Su-27 slowly landing over the airport. The scene where Maozi uses the AL-31F engine to blackmail us will probably not happen again in the future.
The Su-27 fighter slowly stopped at the end of the airport runway, before Lei Yong opened the flight hatch.
Enthusiastic people have gathered around the plane.
After Lei Yong carefully climbed off the plane, he came to Zhang Zhengjiang and saluted excitedly:
"Reporting to the leader, test pilot Lei Yong has successfully completed the test flight mission! Please give instructions!"
Zhang Zhengjiang was also very excited, held Lei Yong's hands and said:
"Thank you for your hard work, you are a hero of our Air Force!"
At this time, other people present were also very enthusiastic and stepped forward to hug Lei Yong.
Even Zhang Xingyang was no exception. He was infected by the warm atmosphere and hugged the test pilot hero.
In this way, in an atmosphere of joy, the WS-10 engine successfully completed its first air operation.
Although the extreme performance of the engine has not been tested yet, the complete success of this test flight still gave everyone a lot of confidence.
At least this represents that the WS-10 project has made staged progress and has produced the first batch of engines that can be actually used.
