Dominate South Asia

"Mr. President, all our other tasks are progressing smoothly. The new optical landing aid equipment ordered from the United States has also been installed." Liu Taoshan, the chief engineer in charge of the entire restoration project and a veteran shipbuilder from Eastern countries Said to Mhamad.

Hamad nodded excitedly. He knew that landing a carrier-based aircraft on an aircraft carrier was extremely dangerous. In addition to relying on the skills of the pilot, it also required various advanced auxiliary means, such as this optical landing assist equipment. It's just very important.

"Well, very good." Mhammad said: "If a carrier-based aircraft is to be compared with a land fighter, the most important thing is to be able to take off and land on an aircraft carrier."

"We have solved the landing problem, but the take-off problem, according to what you said, really cannot be solved." Liu Taoshan said to Mhamad.

"Why?" Mhamad asked.

According to Mhamad's idea, the catapult is first used to accelerate. After the catapult is accelerated, it can then take off from the front jump deck. This can combine the two advantages of the catapult and the jump deck. When the catapult is insufficiently powered, In this case, this is the only way to take off the Tomcat.

"Because the jump deck cannot just be extended in front of the original deck. It must start from the middle of the takeoff and gradually have an upward sliding angle." Liu Taoshan said.

His words immediately made Hamad understand.

If you want to eject and take off, the catapult must be straight, and the deck must be flat. If you want to take off by leaping, the deck will gradually climb higher from the middle of the take-off, and the angle will get higher and higher, and finally reach the required height. angles, the two are contradictory.

In later generations, although the Soviet aircraft carrier Ulyanovsk. A combination of two take-off methods was also used, but the catapult take-off was used on the angled deck and the jump was used on the bow deck. The two were not unified.

If you want to use the two together, that won't work.

"If you want to put it all together, there are only two options. The first is to completely lengthen the bow deck and extend it to more than thirty meters. Make a jump deck. The second is to eject the "Move the instrument back to the middle of the deck." Liu Taoshan continued: "But both of them have congenital flaws. If the deck is moved forward, It will cause the front and rear weight of our warship to be unbalanced. When encountering strong winds and waves, the bow will sink seriously. If the weight of the rear deck is increased at the same time, the weight of the upper deck will increase and there will be a risk of capsizing. Moving the catapult backward will cause the take-off area and landing area to overlap, which will cause serious interference for operations on the deck.”

Liu Taoshan clearly stated the shortcomings of the two situations. After repeated deductions, it was found that neither situation could solve the existing problems. In other words, the plan proposed by Mhamad was completely feasible. Doesn’t make sense.

Hear what Liu Taoshan said. Hamad nodded: "Indeed, we have only one choice, either eject or leap."

"We have designed two new plans for the two options. Now, it depends on your choice." Liu Taoshan said.

Either use the catapult and abandon the leap. Or completely modify the front deck to only have a jump function.

If Mhamad had to choose, Mhamad would have no second choice, it would definitely be the catapult, because. Only a catapult can take off the E-2 early warning aircraft. In the absence of early warning aircraft, the combat effectiveness of the aircraft carrier will be greatly reduced.

"Use the catapult." Mhamad said: "This will also require the least modification to the deck."

Comparing the two ideas, catapults are a better choice. In addition to early warning aircraft, catapults are used. The deck is straight. In this case, the space at the bow of the ship can also temporarily park aircraft, Kuznetsov, and the original aircraft carrier. The displacement is large enough, but the jump deck takes up all the space at the bow, making it impossible for carrier-based aircraft to be arranged at the bow. Since the deck space is limited, the aircraft must be dragged out of the hangar first, which will lead to reduced efficiency.

"Okay, then we will use the catapult, but I have a new idea." Liu Taoshan continued.

"What do you think?" Hamad asked.

"Catapults are all made in sections. The C-11 catapult we are ordering now has arrived. We can order a few more sections as spares, and then dig out grooves behind the deck, so that , we can put down two more sections, and the length of our catapult will increase. By increasing the length, we can add more ejection capabilities.

Just like the barrel, the longer the barrel, the longer the energy of the gunpowder is released, and the greater the muzzle velocity of the cannonball.

The C-11 catapult, as an excellent catapult designed in the United States, can originally be increased in length.

"Well, this is a good idea." Mhamad said: "However, the length of the catapult is only one aspect, and we have to consider other issues."

In addition to the piston and cylinder, the catapult also has, more importantly, a tank that stores high-pressure steam. In later generations, China has been unable to build its own catapult, which has a lot to do with this storage tank. This type of tank is a large-sized, high-pressure container that must withstand considerable pressure. In the chemical industry, nuclear industry, energy and aerospace technology, the advanced nature of this kind of can reflects the level of a country's heavy industry.

Although there are strict requirements on can-making materials, manufacturing equipment and welding processes, when used in aircraft carrier catapults, there are requirements on the number of uses, weight restrictions and high temperature resistance, making manufacturing even more difficult. It is made of heat-resistant special alloy steel, has good creep properties and tensile strength, and has to withstand hundreds of thousands of ejection pressure and pressure relief fatigue cycles.

For example, a common method is to pass a steel pestle through a steel ingot and repeatedly forge it into a link shape. After turning, several links are welded into a cylinder, and the heads on both sides are pressed out or divided into pieces using a hydraulic press of more than 10,000 tons. Pressed out, then machined and then welded. This difficulty even exceeds the catapult cylinder.

A simple gas storage tank can reflect the industrial level of a country. Hamad attaches great importance to this aspect. He knows that as long as this cylinder is lengthened, if there is not enough steam, the goal of increasing ejection power will still not be achieved.

"Another difficulty is the gas storage tank." After hearing Mhamad's words, Liu Taoshan continued: "If we want to build a large gas storage tank, we may not be able to build it, but now, we just need to build it in the original On top of the gas storage tank, a small gas storage tank is connected in parallel. The capacity only needs to be enough to use the extra cylinders. We can build it with confidence. "

Hearing this, Hamad was immediately delighted. This was also a simple solution. On top of the original one, he added a small solution to the problem!

The difficulty of manufacturing a steam storage tank is relative and mainly depends on the diameter of the tank. When the diameter is smaller, the difficulty of manufacturing a steam storage tank that can withstand the same pressure will be greatly reduced.

In this way, the catapult problem is finally solved!

"Through our methods, we can ensure that the Tomcat fighter jet takes off from the aircraft carrier, but it cannot take off with a full load. If you want to continue taking off with a full load, you have to think of other methods, such as increasing the thrust of the Tomcat fighter jet's engine." Liu Taoshan Said to Mhammad.

Increase thrust! This solution is being solved by Mhammad! The negotiations with the Americans will definitely be reached in the end. When the F110 engine with greater thrust is used, the reliance on the catapult will definitely be reduced!

There is a big performance gap between taking off with a full load and being able to take off. For example, in later generations, our country's J-15 was able to take off from the Liaoning, but it took off with half a tank of fuel and could only carry one C-602 in the air. Anti-ship missiles and a combat radius of only 250 nautical miles. Although the J-15's airframe is very good, it is limited by insufficient take-off power.

"Well, let's follow your plan." Hamad said: "You are all experts, only I am a layman."

"In addition to the catapult, there is another problem." Liu Taoshan said: "It is the problem of the aircraft carrier's elevator."

The aircraft carrier's fighter jets are usually stored in the hangar below, and maintenance and repairs are also done in the hangar. Therefore, when needed, they have to be lifted up from the hangar, which involves elevators.

Later American aircraft carriers had side elevators. In this way, they would not interfere with deck operations during lifting, and take-off and landing would not be affected by each other.

However, the current ship in Pakistan is a retired US aircraft carrier. It was converted from a straight-through deck aircraft carrier into an angled deck. When it was decommissioned, there were only two catapults on the bow and no catapults on the angled deck. Besides this, what was even more inconvenient was that one of the elevators was right in the middle of the two catapults taking off!

That's right, it's in the middle. In the past, the American direct access deck was lifted and lowered at this location. But now, this elevator has become useless. When it is working, fighter jets cannot be ejected from the deck. This is a big hole, and After the aircraft is brought up, it will also interfere with the ejection work.

Since it's useless, why not block it completely! This is what Liu Taoshan meant. The extra space below can accommodate one more fighter plane!

After hearing Liu Taoshan's description, Hamad said: "Okay, let's adopt the plan you mentioned! Our first aircraft carrier is experimental in nature. If it is inconvenient, we will change it again!"

With only such an aircraft carrier, it is okay to scare the Indians. But one day, it is completely impossible to confront the Americans at sea. Therefore, the greater significance of this aircraft carrier is to cultivate naval aviation power for Pakistan! This is a seed, waiting to take root, sprout, and thrive! (To be continued ~^~)
