Now, the Tomcat produced in Pakistan has fully replaced the 110 engine with a maximum afterburner thrust of 120 kN. This engine imported from the Soviet Union has a maximum afterburner thrust of 142 kN. The thrust without afterburner is also as high as 84 kN. The prototype of the Tomcat fighter, the t30 engine, has a maximum afterburner thrust of only 93 kN. △↗,

Therefore, after installing this engine, theoretically, this fighter can definitely have supersonic cruise capability! An important indicator of the fourth-generation aircraft is supersonic cruise!

This is also related to the aerodynamic layout of the aircraft. If it is a conventional aerodynamic layout, it is necessary to have an engine with a thrust-weight ratio greater than 10 in order to conduct supersonic cruise. The Tomcat is a fighter with variable sweep wings. When the wings are swept, the drag is greatly reduced, which is very suitable for rapid sprints. Therefore, supersonic cruise can be carried out under the engine power limit!

Supersonic cruise! It means that fighter jets can quickly reach the battlefield, and when they leave the battle, they will quickly evacuate from the battlefield. It is not advisable to rely on the engine to turn over after the engine to enter the supersonic state like the MiG-25. When the engine is over, the fuel consumption rate of the engine surges and cannot maintain a long-term continuous flight.

"Chief Engineer Yang, aren't you responsible for new projects in China?" Mhamad asked Yang Wei.

"The project has been developed." Yang Wei said to Mhamad: "The two-seater fighter has completed a comprehensive test flight mission and has been successfully finalized. Now, our mission is to fully develop our fourth-generation aircraft. I mainly ask for this supersonic cruise test. When this experiment is over, we should be able to determine the selection of our fourth-generation aircraft."

Fourth-generation aircraft! China's Chengfei hopes to develop a double-issue large version based on the J-10, while Pakistan's suggestion is based on the Tomcat. The two sets of plans are still in the demonstration stage, but now the results will be released soon.

"Okay, we have selected the model and we can enter the full development." Mhamad said.

Although the variable sweep wings cause the space under the wing to be unable to be utilized and the hanger cannot be installed, otherwise the collision will occur when the wing sweeps, the fourth-generation aircraft must use the built-in bomb bay to maintain good stealth performance, so this is no longer a disadvantage.

In the eyes of everyone, Kamal walked to the fighter jet. Over the years, Kamal has grown into an excellent test pilot, serving as the captain of the test flight brigade. Testing supersonic cruise was an ordinary mission for him, but another extraordinary mission. This is the ability that only the fourth generation aircraft has!

"Report to the President. Pakistan's First Test Flight Brigade is preparing to conduct a modified fighter test flight. Please instruct the captain Kamar." Kamar said to Mhamad.

"Science, rigorous, you are the releasers of the war eagles and the heroes of Pakistan. I wish you a successful return." Mhamad said to Kamar.

"Yes." Kamal replied loudly and walked onto the fighter plane.

Behind him, the radar operator followed the plane, and the two of them made preparations before takeoff in an orderly manner.

With the roar, the two engines at the tail were started. Light blue flames emerged from the tail nozzle, and Kamal's mood surged, as if he had already felt that the engine was about to push the fighter plane and carry out an extraordinary flight.

After confirming that all the data is normal, Kamal turned on the afterburner and released the wheel. Suddenly, a strong sense of pushing back came, just like a catapult on the aircraft carrier!

The two al-37 engines, which output nearly 300,000 knots of thrust, pushed the Tomcat fighter to quickly glide on the runway, almost only 200 meters, and the wheels in front had already left the runway.

Great! Kamal experienced this stimulating acceleration. If all engines of this thrust level are replaced, the catapult power will not need to be adjusted to the maximum when taking off on the aircraft carrier, and can take off at full load!

Two hundred meters! The most awesome-22 in later generations also requires a takeoff distance of about 200 meters, and it is still the result of having a vector nozzle! However, the Tomcat is not equipped with a missile, which is also an important aspect of shortening the takeoff distance.

After taking off, Kamal pulled the operating lever backwards, and the fighter climbed up quickly. It can be felt that after replacing the new engine, the climb rate of the Tomcat fighter has also greatly improved, which has exceeded all the third-generation aircraft in service!

Generally speaking, cruise will be at high altitudes. After all, the air at high altitudes is thin and the air resistance is small, making it easier to reach high speeds. The maximum speed of all aircraft is achieved at the ceiling.

Climbing to a height of 15,000 meters, Kamal leveled the fighter plane and looked at the clear sky around him. Kamal was in a good mood. He calmly reported on the radio: "He has reached the predetermined height and is ready to start the test!"

The engine's afterburner was turned off, Kamal pushed the throttle to the maximum, the wing swept back, and the fighter began to sprint forward quickly, and the speed became faster and faster.

The Mach watch in front is constantly rotating, Mach 0.6, Mach 0.7, Mach 0.8... Kamal, wearing an oxygen mask, has no expression on his face, and the light of his eyes keeps staring at the instrument.

When it reached Mach 0.9, a special white airflow appeared at the front end of the machine head. Then, suddenly, these airflows flowed backwards, and the machine head pierced the middle of the airflow and turned into a cone! It has exceeded the speed of sound!

The fighter planes are still accelerating.

Mach 1.1, Mach 1.2, and finally stabilized at Mach 1.3!

Just like in computer simulation, after replacing the al-37 engine with a static thrust of 84 kiloni, the Tomcat fighter can reach a speed of Mach 1.3 without turning on the afterburner!

The radar operator in the rear cabin was also paying attention to the screen in front of him. At this time, the information on oil consumption was displayed on the screen.

Supersonic cruise not only can you reach supersonic speed without turning on the afterburner, but also need to maintain this state for at least twenty minutes! This is of practical significance. If you can only perform a few minutes of supersonic cruise, it is useless.

How long it lasts depends mainly on the fuel consumption rate. The MiG-25 is also a fighter that can be cruised at supersonic speeds, thereby achieving rapid interception capabilities. However, this ability is exchanged for huge fuel loads. The huge body of the MiG-25 has a fuel load of up to 16 tons! It is almost heavier than a -16 fighter full of weapons.

Now, the Tomcat fighter is completely realized with a low fuel consumption turbofan engine. The Tomcat fighter is cruising at an altitude of 15,000 meters. If it is a conventional aerodynamic layout, this engine will simply not allow the fighter to achieve supersonic cruise!

Yang Wei on the ground kept listening to reports in the air. His posture was normal and his fuel consumption was only ten percent higher than that of the 110 engine. He had already begun to make a choice in his heart.

The technology of Tomcat fighter jets has been fully understood. On this basis, it seems to be better than the J-10's dual-engine large version! After all, supersonic cruise means that fighter jets can quickly reach the battlefield. For China, which has a vast land area, this ability is even more important. It can completely reduce a large number of front-line airports, reduce the size of the air force, and replace it with high-quality and capable air force!

The Chinese Air Force has a huge fleet, with the number of J-6 fighter jets reaching thousands at peak. However, what about the actual combat effectiveness? The simulated air battle with Pakistan shows that the Chinese Air Force has no chance of winning in front of the Pakistani Air Force.

Now, after hardships, Cheng Fei has finally developed the third generation of J-10 fighter jets, greatly shortening the gap with foreign countries. However, at this time, the United States has begun to develop fourth-generation aircraft! China must continue to develop fourth-generation aircraft so that it will not be left behind.

Stealth and maneuverability are important, but supersonic cruise capability is also an essential factor for fourth-generation aircraft! Although President Mhamad has never conducted professional studies on aircraft design, he looks down from a very high altitude, and every time he puts forward the opinions, it turns out to be correct.

It seems that after I went back, I suggested to Mr. Song that the Pakistani solution should be adopted in the direction of the fourth generation of aircraft!

The test flight in the air is still continuing, time is slowly passing, and the fuel in the aircraft is also slowly consuming.

A total of half an hour of supersonic cruise was conducted! This will be recorded in the history of Pakistan's aviation! Kamal was excited and said to the radio: "The supersonic cruise test has been completed. Please conduct a maximum speed test before returning!"

"Can."

Hearing the sound from the headphones, Kamal turned on the engine's afterburner.

The feeling of pushing the back came again, and the speed of the fighter was increasing rapidly.

Mach 1.6, Mach 1.7, almost quickly, it surpassed Mach 2, and continued to accelerate, Mach 2.2, Mach 2.3!

In the past, Mach 2.3 was already the maximum speed of this fighter, but now, it has exceeded Mach 2.3, and the powerful engine is driving the fighter and continuing to accelerate.

Mach 2.4, Mach 2.5!

"Be careful, the speed should not exceed Mach 2.5!" The voice of the ground commander came from the headphones.

"Received." Kamal carefully closed Juli and prepared to return.
Chapter completed!
