As if hearing the call of this colleague, Edwards' hand quickly flicked the switch on the side, afterburner five!

"Oh God, we're running out of fuel!" Brown in the back compartment shouted.

When they came out this time, they didn't think it was a difficult subject to fight, it was just a matter of a few clicks, so they didn't fill up much fuel, just like the usual test flight subjects.

Now, with these maddening problems, Edwards is going crazy.

Edwards in front of him was indeed crazy, and he shouted, "shut up! Then, he held the lever back into his arms.

When talking about the afterburner of the fighter, it is directly to turn on the afterburner, but in fact, it is not so simple, for example, the afterburner of the Tomcat fighter has a total of 5 levels, the smallest level of 1, the maximum thrust of level 5, and the maximum thrust of 9.3 tons, which is achieved under the maximum afterburner.

With the 5-stage afterburner turned on, it can feel like you've been kicked hard, and this strong push back feeling comes at the cost of a spike in fuel flow to 907 kg/min.

That is, it can consume a ton of fuel in a minute!

The fuel capacity of the F-14 without the auxiliary fuel tank is 7257 kg, and if it keeps flying at afterburner 5, even if the engine can withstand the afterburner for a long time, the fuel will be consumed rapidly.

When flying a tomcat, when the instructor explains this part, he will ask a question: "How many minutes can you calculate how many minutes you can fly like this?"

Not to mention this flight, they only filled up more than two tons of fuel before taking off, and now Edwards is flying in the afterburner 5 state like this, and the fuel is less than 1 ton, they will lose fuel in a minute, and then fall like a big rock.

But now, Edwards, who has gone mad, can't listen at all.

If it is a pilot from another country, when flying, you must always calculate the fuel consumption, when to return home, etc., but American pilots rarely think about it, and they will even use up the fuel in battle.

They are not afraid, because the United States has the largest fleet of air tankers in the world, and they have run out of fuel and can fly to air tankers to receive refueling.

For example, there are US Navy fighter jets training in the nearby airspace, and he can call for refueling in the air at any time, and it is okay if he does not fly back to the base.

The wings of the Tomcat fighter shrank backwards and brushed to the back, this action made Qin Feng behind look envious, even in the later generations, there are many Tomcat fans, everyone's favorite thing to see is the state of this variable swept wing changing in the air, at this time, there is an indescribable beauty.

Under Qin Feng's gaze, the Tomcat fighter began to climb upward.

If the thrust-to-weight ratio exceeds 1, then the fighter can climb vertically without difficulty. For example, the Air Force's F-15 is such a leader, it relies on a strong engine and a lighter body, it can climb vertically effortlessly, and in air combat, it can get rid of its opponents with this strong performance.

But not the Tomcat.

Because the Tomcat has an empty weight of 18 tons, the two engines can provide a total of 18.6 tons of thrust, and it can climb vertically effortlessly only if the internal fuel is less than 600 kilograms, and there is no external plug-in.

And now, the fuel in the Tomcat fighter is less than 1 ton left, and the mass of the two pilots is still more than 19 tons, so the Tomcat fighter will definitely be slower and slower in the upward climb.

This is also the reason why the Tomcat fighter is equipped with the F110 engine, which has a thrust of more than 12 tons for a single engine, and the maximum thrust of two 24 tons is enough for the Tomcat fighter to have a load capacity of more than 6 tons in air combat conditions, while also being able to climb vertically.

Only a Tomcat fighter equipped with an F110 engine is a real Tomcat and a super Tomcat!

When he watched the Tomcat fighter begin to climb, Qin Feng knew that he could not catch up anymore, although the thrust of the Tomcat fighter was insufficient, but the thrust of the MiG-21 was even more insufficient.

MiG-21 is a small aircraft, the empty weight is only 6 tons, now, because of Qin Feng's stingy use of fuel in the plane, there are now nearly 1.4 tons, its engine, can only provide more than 6 tons of thrust, so, its thrust-to-weight ratio, is far less than 1, if you follow the climb, it will definitely be thrown off soon, and then, the plane in front can easily turn down, chasing their own ass beating.

That's the gap, the absolute gap.

Heavy engines, the purchase price is quite high, and the price of operation is also very high, which makes some countries daunted, and they have chosen light fighters, such as the F-16, a single-engine fighter, which has become the world's best-selling fighter in addition to the MiG-21.

However, for a big country, there must be a twin-engine heavy fighter like the F-15 and Su-27, and heavy fighters are the necessities of a big country.

It has two engines, but the weight of the fuselage does not increase to twice as much, so its climbing ability is quite strong.

There is more space in the fuselage, you can have a large range, you can have enough space to update, upgrade the fire control system, etc., which cannot be done by light aircraft.

What's more, there is now a gap between second- and third-generation aircraft.

Qin Feng's radar, at this time, the light point of the target had already appeared on the screen, and if he was given a few more seconds, he would be able to complete the locking action, but now, as the other party climbed, it quickly got out of the radar's field of vision, and the elevation angle of the radar was not enough, and the distance was too close.

What to do? Do you want to go along?

Qin Feng wouldn't do that, the horizontal contest can also be skillful, this kind of vertical climb is a real competition, he has no chance to win at all.

And just as the Tomcat pulled up and climbed vertically, Edwards continued to push the lever, and the fighter began to rotate around the vertical axis as it climbed.

If the planes behind catch up, the two fighters chase each other and climb, and they can form a very beautiful scissor climb trajectory.

As he climbed, Edwards turned his head over and quickly looked at the airspace below, which was also turning at three hundred and sixty degrees as it turned, and then he saw the bright spot.

It's him, MiG-21, Qin Feng! Edwards was overjoyed, you continued to hide behind, you followed after you, and now, I have found you, see how you still run!

At this moment, Edwards felt that the victory was in his hands.
