Chapter 452: The Controversy of Catapulting and Leaping
The deck is wide, this aircraft carrier, no, a heavy aircraft-carrying cruiser, is more than three hundred meters long, standing on the wide deck, you can feel how huge this steel sea monster is.
A person, standing on this, will feel his own insignificance.
Mhammad looked at the leaping deck in front of him, and sighed in his heart, at the beginning, he almost transformed Pakistan's aircraft carrier into a leaping deck, but now it seems that this is not correct.
The jumping deck is almost from the middle of the runway, and it begins to tilt upward, until it reaches the bow of the ship, and it is the most warped, so that the front end of the deck has no other purpose except for allowing aircraft to take off, unlike the American aircraft carrier, the front end can be used as a tarmac. This is a huge waste of space.
In addition to this waste, another point is that the bridge of this aircraft carrier is very huge, almost twice as large as that of American aircraft carriers. Compared to the lower deck, where there is no sunlight, everyone likes to live on the bridge on the upper deck, so most of the space on the upper deck is used to house the officers on the warship.
If the bridge is reduced, there will be at least two or three more places on the deck for the aircraft to stay, and it is much more efficient to operate the aircraft directly from the deck than to use a lift to transport the aircraft from the lower hangar.
With a standard displacement of 46,500 tons and a full load displacement of 61,300 tons, this aircraft carrier far surpasses the previous Kiev-class aircraft carriers and meets the standards of heavy aircraft carriers.
"Pakistan's aircraft carrier Endeavour, how does it compare to ours?" Mkhamad was looking at the island and sighing, when he heard the words of Marshal Ogarkov in his ears.
Although this is just an ordinary greeting, it is still very inappropriate, and who can say that their equipment is poor? Although Pakistan's aircraft carrier is an old-fashioned aircraft carrier, which has been improved several times. The displacement has only increased to 40,000 tons, but it is still the pride of the Pakistan Navy.
"The aircraft carrier has a large displacement, however, catapults are not used." "It makes it difficult for fighter jets to take off," Mhammad said. ”
Catapult! Of course, Mhammad also has pride, although Pakistan's aircraft carriers are old. However, it was a steam catapult that was used! And the current aircraft carrier of the Soviets uses a jumping deck.
The Leap Deck is a lazy shortcut, the British did not have enough financial resources to build large aircraft carriers, so they decided to develop small aircraft carriers, the steam catapult was too bulky, so they came up with such a form of Leap, and used it on medium and even large aircraft carriers. There are only the Soviets in front of them.
Hearing Mhammad talk about catapults, Makarov's eyes lit up, and Makarov had been struggling for a long time over the issue of steam catapults.
"Our carrier-based aircraft, without the use of catapults, can take off." Just after Mhammad finished speaking, a technician said: "Our aircraft has an outstanding thrust-to-weight ratio. Just using the skiing runway, you can take off successfully. ”
Hear this. Mhammad suddenly secretly screamed in his heart that it was not good, bad, he just said that, and as a result, the internal contradictions of the Soviets were provoked again.
Globally, only Americans have catapults. However, it is not that the USSR could not develop it, but because of the smoke grenades put by the Americans.
The Americans have counted the bad aspects of catapults, which are complex in structure and prone to failure. Steam consumes a lot of energy and outweighs the benefits, so the British jumping deck is very popular with Americans.
The Americans succeeded in fooling the Soviets, and within the Soviet military, there were not a few brick-builders who believed that catapults were not necessary to equip them, among them, the main ones were aircraft designers. They believe that if the aircraft uses a catapult to implement forced acceleration and take-off, it is necessary to strengthen the aircraft structure, and the strong acceleration will make the body bear huge forces, and if strengthened, the performance of the fighter will be reduced, and the failure rate of the aircraft will be greatly increased.
Even with their butts, they can think of what kind of idea these people are fighting, they don't want large-scale changes to their planes, especially the Su-27! Due to the problem of the nose counterweight, this kind of aircraft has to lose weight, and even the girder is punched into the hole, so that this kind of aircraft can be put on the ship, just to bear the impact when landing, and the increased weight is enough for a headache, not to mention taking off, constantly strengthening, which will make the fuselage very bulky and greatly reduce the air combat capability.
To study aircraft carriers, the Soviets built a large carrier-based aircraft land-based simulation training system at the Saki airbase on Ukraine's Crimean peninsula. Including the Т-1 type ground skid deck, carrier-based aircraft landing arresting devices, command and control systems and other facilities. From the outside, it is exactly the same as the upper deck of the aircraft carrier, and in order to simulate the wind and waves encountered by the aircraft carrier at sea, the entire deck can also be shaken from side to side by the action of hydraulic cylinders on the lower deck. The entire system was officially put into use in 1982, and the Soviets named it "Nitka". It can be used both to study technology and to train pilots.
In later generations, when the Soviet Union collapsed, this system was naturally left to Ukraine, and as a result, the Russians wanted to train pilots of naval carrier-based aircraft, and they had to rent it here.
In order to develop an aircraft carrier, the Soviets also began the development of catapults simultaneously. In 82, the development of booster equipment began, first a 1:10 catapult model was manufactured, the first physical catapult was built in mid-83, and in 86 this booster equipment began to be installed in the "Nitka" aircraft carrier land test system, with a catapult cylinder length of 90 meters. After two years of testing, in later generations, in 88 years, this catapult passed the joint acceptance test of the state and inter-department, and the Soviets completed the development of the catapult.
It's 87 now, the catapult is still experimenting, and the quarrel about the catapult is also chattering.
The aviation personnel thought that their planes could take off without a catapult, that thing was purely cumbersome, and that the pilot would be quite uncomfortable to eject and take off.
And the engineering and technical personnel of the Black Sea shipyard gradually leaned more towards the opinion of aviation designers, believing that catapults were not needed.
But at the same time, the aircraft carrier designers and the military of the old Neva Design Bureau sharply refuted the "theory that catapults are useless." The two sides are at loggerheads.
The military has a clearer understanding that catapults can make carrier-based aircraft have real combat capability, and gliding and jumping off is just a shortcut but reducing performance.
Even Gorshkov, who stepped down as commander of the Navy in 85, said: "If we do not provide our carrier-based aircraft with the ability to catapult and take off, our group will not be forgiven by history." ”
It is a pity that neither the current Tbes nor the second Riga use catapults, and only the third, the nuclear-powered aircraft carrier "Ulyanovsk", planned to equip 2 catapults on the beveled deck.
The person in front of him may be a slippery jumper in the Black Sea shipyard, or an aviation designer, to coordinate aviation issues on aircraft carriers. Facing this man, Mhammad knew in his heart that if he wanted to convince them, he needed to speak with facts and figures.
"We use catapults to make the Tomcat fighter fully loaded, that is, with six Immortal Bird missiles, four Sparrow bombs and two Sidewinder missiles mounted, the aircraft can take off from the aircraft carrier with full fuel, cruise for half an hour on the 600-kilometer defensive circle around the aircraft carrier, and when we return home, we can also have one-tenth of the fuel, and when we mount four Immortal Bird missiles, our cruise time can be increased to forty-five minutes." Mhammad said, "Where's your jumping deck?" Can your carrier-based aircraft take off with full fuel? ”
Joke, the Su-27K with four redundant digital telex and the addition of front canard wings, although the external load of the Su-33, which was later named Su-33, reached 6,500 kg, but the maximum weight should be only 26 tons if it takes off on the sliding deck at the bow of the aircraft carrier, and the take-off weight will be reduced if the weather conditions at sea are bad. Even with a take-off weight of 26 tons, the Su-33 can only carry about two tons of payload under the condition of 60 percent fuel, that is, the weight of 8 air-to-air missiles used in basic air combat.
The powerful size of the prototype of the Su-33 has been wasted, and it can neither be fully fueled nor fully loaded, which completely restricts the play of combat effectiveness, so that the air time of this heavy fighter is shortened, and the weight of the weapons carried is also greatly reduced, compared with land-based fighters, it is also incomparable.
"We can refuel with a companion." N. S. Chernyakov, a technician of the Sukhoi Design Bureau, who coordinates the construction of aircraft carriers here, faces the President of Pakistan without the slightest stage fright. If you want to increase the amount of ammunition you carry, you can reduce the fuel before takeoff, hang more bombs, wait until you take off, and then use another fighter to carry all the fuel, and after flying up, you can refuel your partner so that this fighter has more fuel.
"Not bad." Mhammad nodded: "Take off ten fighters, five for combat, five for refueling, half of the planes on your aircraft carrier are tankers." ”
After Mhammad said this, the other party's face was embarrassed, this way can only be a tricky way, in actual combat, if this is the case, it is really inappropriate.
"Besides, the use of leaping also seriously restricts aircraft with insufficient engine performance, such as carrier-based early warning aircraft, even if you can fly with a glide jump, the time to stay in the air is greatly shortened, and if you want to endurance, you have to refuel the aircraft." Mhammad put the word tanker and said it very heavily.
Even the Soviets thought that the Yak-44, a twin-engine propeller designed specifically for aircraft carriers, could take off without ejection, but, unsurprisingly, this would limit the fuel load of the aircraft, and the aircraft would not be able to take off with full fuel at all.
