Chapter176 Test flight

 The output of the fighter jet's engine is stable within a reasonable range, pushing the fighter jet away from the ground at high speed.

With the help of the aerodynamic optimization brought about by the forward-swept wing attitude, the fighter's lift off the ground speed is much lower than that of ordinary fighters. But what is more amazing is that even if it takes off the ground at a low speed, the fighter's stability is excellent and its climb rate is very low.

Don’t fall behind.

With the advanced flight control system, the fighter plane is in a stable flight state except for the inevitable bumps when accelerating and taxiing on the runway. Eileen directly told Wang Yu that after her judgment, the fighter plane's

The degree of shaking was much lighter than the three fighter jets he had flown before. It can be said that the flight control system and mature loss-of-volume nozzles helped a lot.

Wang Yu has always been curious about the driving feel of the Su-37, a fighter jet with a displacement nozzle, and now his dream has finally come true.

When the pilot is operating, it is obvious that he can feel a very "soft but fast" feeling. Although it sounds contradictory, the general meaning is that when the pilot wants to adjust the attitude of the fighter plane, the fighter plane responds very quickly, but it does not respond very quickly.

In the situation where the attitude of the fighter plane changes too much in an instant, it is like the fighter plane's response can always be within a suitable range.

I don’t know whether it’s because Wang Yu’s hands are relatively stable, or because the fighter aircraft has made new improvements in flight control automation, or because the changes to the input logic and layout of the new joystick have brought about a certain degree of sensory improvement.
In short, Wang Yu felt that when he took off in a real aircraft, the fighter's beautiful maneuvers and smooth response, coupled with the real overload on his body, the combined experience was definitely better than the simulator.
In the blink of an eye, the fighter plane left the scope of the airport and its altitude also deviated from the minimum altitude limit.

After a while, he turned into level flight at an altitude of 5,000 meters.

Wang Yu began to contact the tower. Since in the first flight, in addition to allowing the pilot to experience it in person, the pilot also needed to focus on determining the performance of the fighter aircraft during the actual flight, so Wang Yu needed to start completing a series of operations.<

/p>

"This is Polaris 1. The takeoff has been completed and the fighter plane is in good condition."

Wang Yu truthfully reported the current status.

In fact, you can expand it, for example, the engine output is maintained at xx, the oil pressure is stable at xx, etc., but writing too many words in this way seems to be a bit of a waste of words. Isn’t it because there is nothing worthy of special reporting on the current situation of fighter aircraft, so Wang

Yu's direct report of "good condition" is enough to show that the current status of the fighter plane is normal.

"Understood, Polaris, please follow the briefing before takeoff and maneuver." The tower's instructions came immediately: "Remember the training you conducted on the simulator, please accelerate, decelerate, turn, and roll in order.

Perform the steps of folding and unfolding the wings in the corresponding speed range. After these steps are completed, climb to an altitude of 10,000 meters as planned, enter supersonic cruise, and cruise along the route for more than half an hour. After completing these basic actions, you can return

Base, on the way back you can choose to perform some BFM (basic combat maneuvers) commonly used by fighter pilots, but please note that all your flight areas have been prescribed in advance, do not leave the flight area."

"Received." Wang Yu simply replied.

He looked at the cloudless sky, the deep blue above his head and the vast land beneath his feet. A smile appeared on his lips. He took several deep breaths and clenched the two operating levers with both hands.

"Wow, my dear, my expression looks different." Irene said decisively.

"It's not surprising, it's like a person who has been holding back his desires for a long time has a way to vent his desires. If he can still hold it back, it's really unreasonable." Liu Lingxin also complained.

Although Wang Yu had already started to accelerate the fighter planes to prepare for maneuvers, he still took time out of his busy schedule to say to Liu Lingxin: "People have more than one desire. If you have the ability, come to my room tonight, and I will let you know what 'catharsis' means."

'..."

"I'm going to kill you!" Liu Lingxin blushed: "There is a communication recorder in this cabin!"

It seems that she doesn’t understand anything.

In short, the short conversation came to an end, and Wang Yu began to concentrate on flying.

He maintained level flight and quickly accelerated the speed of the fighter plane.

As the throttle lever is pushed forward to the military push position, the engine has already exploded with powerful thrust, pushing the fighter aircraft to accelerate and fly, and the speedometer rises rapidly - if everything goes well, and the military push position is maintained, the fighter jet will be able to exceed the speed of sound.

There are obstacles in entering supersonic cruise, but at least for now, the fighter plane is still in a subsonic state.

Soon, the speed of the fighter jet exceeded a certain critical point.

At this time, the main control system of the aircraft will automatically retract the wings according to the high speed setting - of course, seemingly for safety reasons, the wing adjustment of the fighter aircraft can only be carried out in a certain speed range, regardless of

It doesn't matter whether it is manual or automatic. This can avoid accidents caused by using the forward-swept wing attitude at supersonic speeds or the wing-retracting attitude in low-speed fighting conditions.

The wings were folded and stored smoothly even during high-speed flight, and the flaps that were originally low in the front and high in the back and the tail that was originally in a high-angle V shape began to slowly flatten at the same time.

This process is not slow, it only takes a few seconds to complete, and the fighter's flight control system also adjusts the thrust direction of the nozzle and the movable airfoil in time. In short, the fighter's flight attitude does not change in any way during this process.<

/p>

After Wang Yu maintained this attitude and flew for a while, he then reduced the engine thrust, causing the fighter's speed to be lower than the critical speed for wing retraction during automatic control, so the wings automatically unfolded to provide better low-speed control performance.<

/p>

"It seems there is no problem with this." Wang Yu reported to the tower.

He folded and unfolded the wings several times, and at the same time performed some basic maneuvers, yaw, pitch and roll in different flight postures. Anyway, he completed the maneuvers of the fighter aircraft on the three axes of xyz.

.

Eileen has been monitoring the fighter plane. She said that the reliability of the fighter plane is indeed as boasted by the military industry executive. When maneuvering, she, as a plane girl, cannot see any possible problems with the fighter plane.<

/p>

At this time, the fighter plane had almost reached the first turning point, and Wang Yu began to prepare for the next step - supersonic cruise.

Wang Yu controlled the fighter plane to climb to an altitude of 10,000 meters. The air here was already very thin and the relative resistance was smaller, so he first pushed the throttle to the afterburner position to bring the fighter's Mach number to a state close to Mach 1, and then

Reduce the accelerator to the military position.

The powerful engine, even when the output is at the military thrust position, can provide the fighter with thrust that is no less than that of an ordinary aircraft engine during afterburner. Therefore, with a harsh explosion, the fighter's speed quickly exceeded m1.0.

.

This is supersonic territory.

On other fighters, it must be in a suitable environment and with a suitable mount, and the speed can only be achieved by pushing the throttle full.

This fighter jet easily crossed the sonic barrier, and while maintaining the momentum of military push, its speed continued to rise.

"I always feel a little nervous." Liu Lingxin could also see the speed from the back seat, so she said: "When I think that this fighter can maintain this supersonic speed for a long time under normal conditions, I have a different feeling."<

/p>

"It's understandable." Wang Yu answered her while looking at the fighter data.

At this time, the speed of the fighter plane has stabilized at m1.7, which is 1.7 times the speed of sound.

This is also the supersonic cruising speed for which fighter jets are designed.

If afterburning is turned on at this time, the speed of the fighter can be further increased, reaching the limit of Mach 3 with a light load - you must know that this is already faster than the top speed of some old-fashioned missiles.

But Wang Yu and the others are not testing today, so they don’t need to test such extreme conditions.

As time passed by, the fighter plane flew steadily at supersonic speed.

A map is displayed on one of the screens of the fighter plane. It can be seen that the flight route of the fighter plane is from northwest to southeast. It has flown from the interior of the empire to the southeast coast in a short period of time. They have flown through many cities along the way.

We passed through many air traffic control areas, thanks to the fact that the military had notified the airspace entry control along the way in advance, otherwise misunderstandings would inevitably occur.

After half an hour of supersonic flight, Wang Yu controlled the fighter plane to retreat from the supersonic state.

"It's so exciting. In a blink of an eye, we are already over the southeast coast."

Wang Yu looked at the coastline not far away and couldn't help feeling a little emotional. This was a speed that the MiG-21, F-15e, and F-4c he had driven before would never be able to achieve. And if he thought about it carefully, this attack on the battlefield

The efficiency is indeed much higher than that of ordinary fighters.

"The flight attitude is normal, the body structure is normal at supersonic speed, the engine output is normal, and supersonic cruise is completed perfectly."

Irene summarized it for Wang Yu.

"Okay, the fuel level of the fighter plane has also been reported to bingo, and we can prepare to return home." Wang Yu said: "It's a pity that today we can only experience the maneuverability of the fighter plane, and the application of the weapon system will have to wait for some time."
p>

"Yes, I am a passenger through and through." Liu Lingxin said.

It took half an hour to fly here, but it was different when flying back.

Wang Yu calculated that using the most economical amount of fuel, which is Mach 0.6 at 12,000 meters, it would take more than an hour to fly.

However, the rest of the things are simple. The point-to-point flight can be completely handed over to the autopilot system, and he can free his hands.

So, Wang Yu set up the fighter's autopilot system and began to return home.

He planned to conduct some basic combat maneuvers when he arrived near the departure airport.

Now, chatting with two girls at an altitude of 10,000 meters can be considered a very romantic thing.
