F-110！ This is the engine of the main fleet of the US Air Force, the F-15, F-16 fighters.

The science and technology of the United States is quite advanced, and this advancement is reflected in the aviation turbine engine, which is the most cutting-edge science and technology, and at the same time adopts a large number of new technologies.

The engine of the third generation of military aircraft in the United States was competed by Pratt & Whitney and General Electric, each developing a new engine, of which Pratt & Whitney developed a new engine based on the JTF22 core engine, and the verification machine was put into operation for the first time in July 1969. In March 1970, it won the GE1/10 engine competition with General Electric, and then began to equip F-15 and F-16 fighters, but there were many problems in reliability, durability and maintenance in the early stage, and even once put the American front-line fighters in danger of grounding.

The F100 engine is the world's first thrust-to-weight military engine with a thrust-to-weight ratio of 8, and it is the main engine in the United States.

At the same time, the United States General Motors, which failed in competition, was not idle, in 76 years, when it saw that the F100 engine made the US Air Force fighter lie on a large scale because of various problems, it began to raise its own funds and built an F101X verification machine, various parameters similar to the F100 engine, this engine at the beginning of development, is aimed at the engine of the third generation aircraft of the United States. Focus on matching the F-16 and F-14 models.

After two years of extensive testing, in 1980 and 1981, it was able to be installed on F-16 aircraft without heavy modifications. In the F-14 test, the aircraft's air time and combat radius were 25 percent longer than that of the original TF30 engine.

As a result, GE got a contract from the military, and the engine had the official number F110 when it was 85 years old. This engine was completely finalized and put into production.

The F110 engine was finalized and delivered in early 1985.

In later generations, the U.S. Air Force followed a two-contractor procurement strategy, and the procurement of F-15 and F-16 fighter engines was divided between the F100 and F110 in a certain proportion. This helped engine manufacturers to continuously improve their engines, and from then on, an engine war began.

(East China's male teeth are itchy, look at our country, concentrate all the energy on tackling key problems, and make out the turbofan ten.) Until now, the performance is still not up to par, and the Air Force would rather continue to import the Al-31 than let this engine equip its own fighters. Look at the United States, the two manufacturers are competing, and the Air Force can choose the best engine from it! Look at the perverted F-119 engine, the scientific and technological strength of the United States is simply alien technology. ）

The originally developed F-110GE-100 has a maximum afterburner thrust of 120 kN. thrust-to-weight ratio 7, this engine. Since it was originally considered for use on the F-14, it was able to adapt to the F-14 fighter with little modification.

So, Grumman abandoned the TF-40, an engine improved from the Spey engine, and directly used the F-110. A new F-14D Super Tomcat fighter was created for the US Navy.

And now, Pakistan's Tomcat fighters are approaching the most advanced in all aspects, for example, they have been retrofitted with APG-71 radars. A new number chain was introduced, the on-board computer was upgraded, and even a xenon lamp was introduced. However, the engine of the Tomcat fighter has always been the original engine, due to the high-intensity flight of Pakistan, the original TF-30 engine has reached the end of life, and it has been replaced with a newer version of the TF-41 engine produced by Pakistan. In the eyes of the Americans, these fighters still use TF-30 engines.

In the past, Mhammad had high hopes for this engine, after all, this is an engine with an afterburner thrust of more than 100 kN that Pakistan can produce on its own, and in the end, the thrust can exceed 11000 N, which can be regarded as a big thrust engine.

However, after all, this engine was improved from the Spey engine, and if it continues to be improved, then the potential is limited. At the same time, the engine of the third-generation fighter of the United States, whether it is F-100 or F-110, the potential of these two engines is very huge, for example, the ultimate improved model of the F-100 engine, F110X, the thrust will reach 160 kN, thrust-to-weight ratio of 9.5, in the absence of more advanced technology, this engine can even be used in the future fourth-generation aircraft. In later generations, there were no advanced engines in China, and the fourth-generation aircraft still used AL-31.

In the past, Mhammad had no other means than to obtain the F100 overhaul line, but now, he finally has enough chips! The Su-27, the dream fighter of the Americans, fell into the hands of Pakistan, so it is natural to squeeze out all the value.

Hearing Mhammad say this, Arnold's eyelids had already begun to jump, as if he had a premonition of something.

"Our Tomcat has begun to lag behind, and at the same time, the original engine has begun to reach its lifespan, and we hope to use the F-110 engine to improve our Tomcat fighter." Mhammad said.

"I'm sorry, but the F-110 is our most advanced engine." Arnold said: "It can't be exported for the time being. ”

When Arnold had said this, he saw Mhammad stand up and stride back, ignoring Arnold in the slightest.

It seems that this matter is going to be in vain! Arnold looked at Mhammad's back, a little anxious, but this could not be agreed to him casually, Arnold had to reflect to the United States.

Mhammad returned to Islamabad, Lilith was already hot for the second time, eating the dishes, Mhammad was still thinking, could it be that in the eyes of the Americans, they would rather not have the Su-27 than give themselves the F110 engine? Before he said anything else, Arnold seemed to know that he didn't just want the engine, but also the production line that the engine piggybacked.

Pakistan needs this kind of engine, which will make it easier for the Panda fighter to take off from the aircraft carrier, and in later generations, after the U.S. Navy used the F110 engine, it was found that when the catapult took off, it did not need to turn on the afterburner at all, and it could take off normally.

"Honey, what's wrong?" Looking at Mhammad's appearance, Lilith couldn't help but ask.

"We want the U.S. to export new engines to us, but there may be resistance from the U.S. side." Mhammad said.

"What new engine? Is it used on Tomcat fighters? Lilith asked, for Lilith, there was only so much she could know.

"Yes." Mhammad said.

"That's too easy, I can contact my father, the Pakistan Air Force is equipped with new engines, and it will also give Grumman a new contract, which is beneficial for both parties." Lilith said, "Those guys in Congress, Grumman will have a way to deal with it. ”

Only then did Hammad remember, indeed, Lilith still has this relationship, Grumman is his wife's maiden family, and with Grumman's lobbying, it will definitely be easier.

Five days later, Arnold came to see Mhammad again.

In the past few days, Zuyev has been in no hurry, and every day he asks when he will go to the United States, but he is shirked on the grounds of safety.

Anyway, Pakistan is not in a hurry, it is the Americans who are in a hurry. "President Mahmad, it's a great pleasure to see you again." Arnold said: "In the United States, we have reached an agreement with Grumman to improve the new engines for your Air Force fighters. ”

"It's long overdue." "If we had known that the terrible TF-30 engine had so many flaws, we wouldn't have bought this fighter from your country in the first place!" Mhammad said. ”

Tomcat fighter, excellent airframe, matched with a bad engine, this is the original words of US Secretary of the Navy Lyman, he used to be the pilot of the Tomcat fighter, has a very deep experience, where is flying the plane, it is simply waiting for the engine!

"But we don't have any more money to buy those engines." Mhammad said.

Listening to Mhammad's words, Arnold's eyelids began to beat wildly again, he knew that Mhammad would not be satisfied so lightly, he must have more plans, he was simply the most sloppy president ever! However, the country really needs that Su-27, when it was learned that a Su-27 actually landed in Pakistan and was almost intact, the top of the Air Force, everyone's eyes flashed like wolves, if it weren't for secrecy, those guys all took a plane and came to Pakistan to watch the Su-27!

I wanted something, but I didn't have the money, so I used that Su-27 in exchange for a new engine for eighty Tomcat fighters. One hundred and sixty units, Pakistan is too shameless!

Arnold cursed in his heart, still with the characteristic smile of a diplomat on his face: "So, what are you going to do?" ”

If the other party is really cheating, let's say it yourself, the internal ex-factory price of this engine is at least 5 million US dollars, 160 units, that is 800 million US dollars! Are they really that embarrassed? That Su-27 is only tens of millions of dollars. Equivalent exchange.

However, thinking of the exchange of the Tu-22 Backfire, if Pakistan does not take advantage of it, it will definitely not let go. (To be continued......)
