Chapter 836: The real goal!

The famous F-4 "Phantom" fighter, Colonel Jalari is very familiar with it.
This dual-engine, two-seater, all-weather long-range supersonic multi-mission fighter developed and produced by Macdonald Douglas of the United States is a typical representative of the second generation of fighters. The design began in 1956, and the first prototype was tested in May 1958. 1961 The US Navy began to be officially delivered to the US Navy in October of 1963. It entered service in the US Air Force in November 1963. It was the main fighter of the US Air Force and Naval Forces in the 1960s and 1970s. It participated in the Annan War and several Middle East wars with outstanding merit.
And because of its excellent maneuverability, before the F-16 entered service, it was a performance aircraft of the US Air Force "Thunderbirds Aerobatic Team".
The performance of this type of fighter is balanced in all aspects. It is not only powerful in air combat, but also capable of attacking ground. It can perform a variety of tasks. Therefore, in addition to the large amount of equipment of the US army, it also won the favor of many US allies in the same period. The production line lasted from 1958 to 1981. The service period and even 2017 before Tan Zhenhua's rebirth were not completely over. The output reached a record 5195, and dozens of countries purchased this fighter as their main equipment. , And among them, they include Britain mentioned by Tan Zhenhua just now, and Ipos during the Pahlavi dynasty.
Compared to the 80 F-14 fighters that are particularly eye-catching because of their reputation, they are composed of 32 F-4Ds, 177 F-4Es and 16 RF-4Es. The total number of F4 aircraft is as high as 225. The backbone of the Ipohs Air Force!
Moreover, this batch of F4 "Phantom" fighters entered service with the IPersian Air Force earlier than the F14. From the purchase of the first aircraft in 1973 to the delivery of these aircraft to Ipers in 1976, the United States successively delivered the aircraft. It has been in service for ten years now.
In other words, the demand for accessories for these F4 "Ghost" fighters is larger and more urgent than F-14!
Colonel Jalari knows very well that the F4 "Phantom" fighters equipped in this country are equipped with two J79-GE-17 turbojet afterburners produced by General Electric Company of the United States, because this is the factory standard. Configuration.
Despite the blessing of the advanced aviation technology of the United States, this type of engine is after all the previous generation of turbojet and is a product of the 1960s. Regardless of the key performance parameters such as thrust, thrust-to-weight ratio, and fuel consumption, it is impossible to match Compared with the new turbofan engines, and more importantly, as the war progresses, F4 "Phantom" fighters with a high dispatch rate are rapidly consuming their flying hours. At the same time, these engines have already The end of life is approaching!
This is obviously a very headache for the Iberian Air Force.
Therefore, the question raised by Tan Zhenhua and the "Speey" engine in front of him immediately made Jalari, who is familiar with the situation, a certain association.
And this kind of association actually made his voice tremble slightly: "Eric, British Air Force, do you use this engine to replace the original standard J79 on their F4 "Phantom" fighter?"
"Bingo!" Xiao Tan slapped his fingers in praise, "Mr. Colonel, you got it right!"
"What's going on, can you tell me?"
"Of course, Mr. Colonel." Tan Zhenhua began to tell: "Things have to be talked about from the end of World War II. At that time, the Royal British Navy started to build two "Eagle" class aircraft carriers, which were later "Eagle" and "Eagle". The Ark Royal, however, when the two aircraft carriers were built, the war was over. The two aircraft carriers were originally designed to carry 100 propeller fighters, but you and I know that after World War II, the aviation industry took place. In a major change, the piston-propeller fighter was completely eliminated by the jet fighter, which caused an embarrassing situation for the two aircraft carriers."
Seeing that Jalalli listened intently, Tan Zhenhua spoke more vigorously, almost spitting out: "The cost of aircraft carrier construction is high, and the service period is long. Of course, the newly built ships cannot be discarded casually. The ship maintained a certain combat effectiveness, and the Royal British Navy carried out a series of modifications to it, including the installation of angled decks, steam catapults, advanced electronic systems, etc., but the biggest problem was that Britain did not use it at the time. The carrier-based jet fighters. And because these two ships are small aircraft carriers with a displacement of about 40,000 tons, the maximum number of jet fighters they can carry is only about 40, and the sum of the two ships is only 80. , Then it is obviously not cost-effective to develop a single model for these 80 fighters. Therefore, Britain decided to purchase ready-made carrier-based fighters to meet their requirements. In the world at that time, they had and only one The choice is the carrier-based model of McDonnell Douglas F-4 "Phantom" fighter."
Having said that, he paused, turned to Jalari and asked: "Mr. Colonel, you Iposs are also users of this aircraft. You should be familiar with its problems, right?"
Jalari nodded and said, "Yes, we know that this aircraft has a large turning radius, insufficient engine thrust, and a long take-off and run distance."
Tan Zhenhua gave him a thumbs up and said: "Mr. Colonel is very professional. Yes, the F-4 "Ghost" fighter is indeed the best of the second generation fighters, but it also has its inherent shortcomings. This shortcoming is for the Americans. It's not a big deal, because they are equipped with a large aircraft carrier of 80,000 tons, with a long runway, and their steam catapults are relatively powerful, so this small problem can be ignored, but for the British, it is fatal Yes, their aircraft carrier is half smaller. Of course, the length of the runway has to be shrunk a lot, and their steam catapult is much worse than that of the Americans. The final result is that they bought the F-4 "Ghost "On the aircraft carrier, we can barely take off with less fuel and less bombs."
"This is obviously unacceptable to the Royal British Navy. Therefore, at their request, McDonnell Douglas, British Aerospace, and Rolls-Royce have jointly modified the F-4 "Phantom" fighter and replaced it with Rolls-Royce. Hangfa, that is, the "Speey" MK202 in front of you, because, compared with the standard J79, this "Speey" engine can provide about 1.3 tons higher than the standard J79. The thrust can also reduce fuel consumption by about 25%. Mr. Colonel, you should know what this means, right?"
Jalari swallowed dryly and said: "It means that the F-4 "Phantom" fighter with the "Speey" engine can not only meet the requirements of a short take-off on an aircraft carrier full of fuel, but also get it. 25% more time spent in the air... Eric, they succeeded, right?"
Tan Zhenhua nodded and replied very positively: "Yes, they succeeded. In fact, for the F-4 "Phantom" fighters delivered to the Royal British Navy, the "Speey" engine is their standard configuration. Of course I also I must remind you, Mr. Colonel, this is not without cost. The high-altitude and high-speed interception performance of the "Phantom" fighter in this state is relatively poor. This is determined by the working principle of the two engines, but compared to the one obtained. On the good side, this price is completely acceptable."
At this moment, Jalari has completely believed Tan Zhenhua’s words. At the same time, he also saw that a great contribution is beckoning to him-because his trip to Xijing in China has plagued the momentum of the Iberian Air Force for many years. There will be a perfect solution to the core problem. This kind of credit is worthy of replacing the three stars on your shoulders with a scimitar wheat ear pattern, right?
Or you have to add a shiny Republic Medal!
"Then, Mr. Eric," he finally confirmed with a dry voice: "Can we get a few Speys for testing? After all, this is a complicated project."
"Of course, my dear Mr. Colonel, I even suggested that one of my elders should help you with this modification. He is not only our top aircraft design expert, but also an aircraft design project he is currently working on. I also use this type of engine. I have rich experience in how to design and modify the rear fuselage of the aircraft according to the needs of this type of engine. So I personally think that he is the best person to help you design a modification plan."
Having said that, he smiled slightly and continued: "As for the engine, that is not a problem at all. We can provide it at any time, Mr. Colonel, as I just said, we have stock."
