J-18 is a typical multi-role fighter, and the biggest difference between a multi-role fighter and a fighter-bomber is that the multi-role fighter maintains a single-seat design, rather than a two-seat design of a fighter-bomber, so only one test pilot was arranged for the first flight of the J-18.

"Master Sun, then I'll go up, you can rest assured, I have been simulating operations on the ground many times before, and the ground sliding test is also done by me, there must be no problem with the first flight, I believe in your design ability, and I also believe in my flight skills."

Anyway, accompanied by Chief Engineer Sun Huizhong, the test pilot boarded the plane and entered the cockpit, and this time the J-18 has made a lot of progress in design, such as considering the possible improvement of carrier-based aircraft in the future, so it directly designed its own folding boarding ladder, so there is no need for a special boarding ladder.

This time, the first aircraft has not yet completed all the avionics management system programming, and the original planned automatic full-aircraft detection function has not yet been developed, but the test pilots still rely on their own ability to skillfully inspect each flight system.

The on-board auxiliary power system was activated, and a small turbojet engine was first started, and its job was to provide all the power needed by the aircraft before the main engine was started, so that the aircraft could not rely too much on the ground power supply to maintain basic needs, and when the voltage could be stabilized, the connection between the aircraft and the ground power vehicle was decisively cut off.

Turn your head slightly to the right, nod your head to indicate that the power supply car can evacuate the scene, and confirm that the power supply car is evacuated to a safe area, and only then did the two turbofan 10 engines start here, this time the turbofan 10 is already a special version for installation on the J-18 test flight, and the engine control system will never have any more problems.

When the two main engines are running, the auxiliary power system can naturally be turned off, that thing is probably used when the main engine is not started, and then the movable wing surface inspection is also very simple, although the J-18 has high technical content, but the airfoil design of the aircraft is very decent, and it is almost difficult to have problems.

After everything was confirmed, he put his head out of the cockpit, and said the last greeting to the engineer team on the ground before the flight mission, and after the two sides saluted and solemnly returned the salute, the engineer team turned around and left with neat steps, and the test pilot also retracted his thoughts, and after sorting out his dress again, he checked whether the seat belt was buckled in place, whether the ejection pull ring was firm, and everything was okay before putting down the cockpit cover.

When the cockpit canopy is lowered, it means that the entire cockpit is separated from the outside world, but the benefits of the bubble cockpit are vividly reflected at this time, although the J-18 still uses the design of the central joystick, but thanks to the huge size of the F-15, the cockpit is also quite spacious, and the pilot will not have any sense of depression in it, which is a congenital disadvantage that small aircraft can not do.

Carefully feel this modern fighter, the mainstream cockpit design of one flat and three down, the color display screen provided by Changhong will display all the necessary flight data one by one, and some button-type control panels are still retained on both sides of the cockpit, but the arrangement is also quite neat, and everything is orderly.

"It's really good, this is a real modern combat aircraft! I don't know how many times the cockpit layout is better than the previous Soviet aircraft, although the lightning is also a flat and three design, but unfortunately the innate limitations of the fuselage have always been less comfortable than the J-18. ”

At this moment, it is probably the time when the test pilot is most proud in his heart, although he has also been in contact with the Su-27 aircraft before, and the fierce temperament is indeed very impactful, but the cockpit and avionics design of the Su-27 is too backward, as long as he flies the J-18 once, if he still wants to experience the old-fashioned avionics of the Su-27, it is simply a fool whose head is caught in the door.

Put on an oxygen mask, everything is in place and you only owe the east wind: "Tower, this is 18002 (18001 in the previous chapter is wrong, it is a static testing machine), everything is normal with my plane, please take off." ”

"The tower understands, permission to take off, a JF-17 Lightning fighter behind your plane will accompany you throughout the flight, good luck!"

"Received"

Didn't turn his head to look at the companion plane not far behind, the test pilot of the 18002 here let go of the carbon brakes, and the unrestrained plane began to slowly glide forward, the silver-gray wheels were not painted in any way, but even this kind of naked. Ben, after spinning, is still better than the green wheels, I don't know how many times.

The fuselage paint of the aircraft has not changed much, it is still based on light yellow, and the seams are outlined in rust green, and the original aerodynamic design of the aircraft is also very aerodynamic, which means that the aircraft itself will be very beautiful, and the current 18002 is the star in the eyes of everyone.

The test pilot increased the thrust of the engine again in the cockpit, and with the increasing thrust of the two turbofan 10s, the aircraft taxied faster and faster, and when the thrust output of the engine reached the maximum unafterburner thrust, the aircraft had reached the required flight speed.

After all, it is a flat wing design, although this will bring an increase in aerodynamic drag in high-speed flight, but it also gives J-18 an incomparable short-distance take-off capability, even if the turbofan 10 engine used temporarily and the planned turbofan 12 complete body thrust gap is very large, but relying on aerodynamic advantages, 18002 is still earlier than the lightning behind the ground.

It wasn't until the lightning flew to the take-off altitude that the wheels of the lightning that accompanied the flight were off the ground, if there was no lightning to make a comparison on the side, it would naturally be difficult for everyone to clearly understand how powerful the J-18's short-distance take-off ability was, but now!

"Good!"

Yang Hui only heard the word "good", and then heard the telescope slammed on the table. Then Commander Zhang's eyes widened, it was too painful, when he was too excited to shoot the telescope on the table just now, his fingers were actually one step ahead of the table, so it hurt!

Seeing the sweat on Commander Zhang's forehead, as well as the unexaggerated expression, as well as the affected part of his right hand that was tightly pinched from side to side, Yang Hui was about to say something, Vice Chairman Liu turned his head and glanced at it, and then there was no follow-up, and at this time, Commander Zhang seemed to have eased up and picked up the telescope again.

Since this is the case, Yang Hui must not care so much, now is the critical moment of the first flight, at this time, the two planes have actually completed the take-off, after the two planes completed the formation, they began to simply fly around the airspace specially zoned for the test flight.

Climbing at a small angle, turning, and shaking their wings left and right, the test pilots in the cockpit tested the first flight subject according to the previous training and simulation process on the ground, and then the two planes flew together in formation over the ground crowd, and the sky could not hear the cheers from the ground, but with the experience of the two test pilots for many years, they knew that the ground must be cheering constantly.

The planned first flight lasted a total of 14 minutes, and it was enough to complete a simple test work in the air within the given time, and as long as it could land safely, the first flight would be a success.

After adjusting the flight attitude twice, the aircraft has been aimed at the landing area on the ground, to reduce the speed, not only need to reduce the thrust to open the speed brake, but also need to manipulate the change of the flaps, to reduce the lift coefficient of the wing before completing the action, the low-altitude and low-speed performance of the straight wing is really excellent, the whole landing action is simply not the slightest sense of dragging mud and water, probably this is already a standard aircraft landing tutorial.

After the front and rear wheels are grounded, the plane has taxied for a distance, and the carbon brake pads began to intervene in the work, relying on the control of the brake brake, the aircraft's taxiing speed will be reduced more slowly, and the first flight did not even use the landing parachute to stop on the runway.
