Chapter 1702: The Solution
Chapter 1702 The Solution
"What's wrong?" Seeing Zhang Lan staring at herself so stunned, although she was very ashamed in her heart, Hu Ruoxi was a little girl after all, her face was very tender, she was embarrassed to look down at her award-winning toes, and asked in a sweet and glutinous voice.
"Oh...... Oh...... It's nothing. Zhang Lan's answer was a little flustered, maybe Hu Ruoxi's emotions infected him, and he felt that his heart seemed to be starting to become a little flustered, and he couldn't control himself.
Zhang Lan, who knew what was going on, was a little depressed, it was not the first time she had seen this girl, why did she still look like a useless pig brother?
"Hmm......" The subtle atmosphere between the two also affected Hu Ruoxi, the little girl hummed softly, secretly raised her eyes to look at Zhang Lan, and hurriedly lowered her eyelids, but not only the whole little face was red, but even the whole neck turned a seductive pink.
This is not good, very bad, but if it goes down, something will happen Zhang Lan shouted depressedly in her heart, if there were only two of them, it would be fine, but if Brother Hu's family was here and his father was here, he would openly flirt with this girl...... Ahem, this ...... This one...... Some of them are good to say, no, if you want to change the topic, you must change the topic.
"By the way, you say, if our country builds an aircraft carrier, what mode of carrier-based aircraft should take off?" Zhang Lan, who was desperately thinking about changing the topic and didn't know which nerve was not right, asked Hu Ruoxi such a sentence like a god.
After this sentence was said, Zhang Lan, who finally reacted, was stunned: Huh? What are you talking to this girl about? A little girl, would she be interested in military issues? Failure, what a failure to divert the topic of
"Huh?" Hu Ruoxi glanced at Zhang Lan in surprise, obviously, she was not a little mentally prepared for Zhang Lan's words.
glanced at Zhang Lan, the little ambiguity between the two just now, although Hu Ruoxi also liked it very much, but he also knew that this place was not ambiguous, Zhang Lan changed the topic in a timely manner, Hu Ruoxi's tense heartstrings relaxed slightly, but I don't know why, Hu Ruoxi felt a little lost.
Biting her lip gently, the little girl glanced at Zhang Lan with some resentment.
Zhang Lan, who was weak-hearted, hurriedly lowered her head, not daring to look at Hu Ruoxi.
But in the end, this girl's background is not simple, she quickly cleaned up her mood, frowned and thought for a moment, "I think it's better to take it step by step, starting from the glide jump take-off, and gradually developing towards the catapult take-off." Of course, there are many shortcomings and restrictions on glide takeoff, and there is no way for carrier-based aircraft to take off with full fuel, and both the number of weapons and the range are limited. ”
"A little modification to the skid take-off? How to modify? Zhang Lan was surprised, among the countries that now have aircraft carriers in the world, only the United States and France can use the catapult take-off method, and the other eight countries with aircraft carriers all use the carrier-based aircraft method that has lasted for decades.
"It's simple, if you take off with a glide jump, in order to let the plane accelerate to a speed that is enough to take off on the short flight deck, isn't the previous practice all the methods of reducing the number of fuel and weapons, if we install a rocket booster with enough thrust on the carrier-based aircraft, won't we be able to make the carrier-based aircraft take off with full fuel? And the aircraft carrier that uses a sliding jump to take off, the take-off frequency of the carrier-based aircraft is not as fast as the catapult take-off, if the take-off method of sliding jump take-off + rocket booster is adopted, I have calculated, the take-off frequency can still be a little faster, and it will not be worse than the take-off frequency of the aircraft carrier of the same displacement that takes off with steam catapult. ”
Obviously, this girl has been thinking about this question for a long time, so after Zhang Lan asked, this girl not only quickly said her thoughts, but also had sufficient reasons. It's not a bad idea, but if it does, it's a good solution.
Zhang Lan fell into deep thought: it is not without precedent for fighter jets to adopt rocket-boosted take-off. During the Vietnam War, in order to save combat take-off time as much as possible and support the front-line combat troops as quickly as possible, the Air Force at that time invented a new fighter take-off method: fighter vertical take-off.
The specific method was to fill up the J-7 fighter at that time with fuel like launching a rocket, mount the weapon, and place it vertically on the belly and wings, and install a total of three rocket boosters. When the combat alarm sounds, the pilot enters the cockpit of the fighter at the fastest speed from the special boarding ladder next to the fighter, starts the engine, and uses the three rocket boosters and the engine of the fighter itself to push the fighter to take off vertically like a rocket, and when it rises to a certain height, the fuel consumption in the three rocket boosters is exhausted and automatically falls off from the fuselage, and the plane has accelerated to a high speed of nearly Mach 0.8 at this moment, and can fly directly to the combat area in the air.
Using this take-off mode, you can save the preparation time before take-off as much as possible, and at the same time, the fighter plane that rises vertically basically does not need to consider the problem of steering: the fighter who takes off vertically, no matter which direction the combat direction is, can easily turn the nose and fly to the combat area, if it is an ordinary taxi-run take-off mode, assuming that the aircraft takes off in the north-south direction, but the combat destination is in the southwest, and the fighter after take-off has to make a big turn, which wastes part of the time invisibly.
Even on aircraft carriers, in the fifties and sixties of the twentieth century, there was a period of experiments in which aircraft carriers and carrier-based aircraft were equipped with rocket boosters to take off, just because the rise of rockets at that time was not long, and many technologies were not up to par, so this sliding jump take-off + rocket-boosted aircraft carrier carrier-based aircraft take-off boom was finally out after several years of excitement and several serious accidents.
Those countries that engaged in this experiment came to the conclusion that the aircraft carrier aircraft adopted the method of glide jump take-off + rocket to boost the aircraft: theoretically feasible, but the safety and safety of the booster rocket is too low, and the probability of failure is too high
In recent years, countries led by the United States have vigorously developed the steam catapult take-off mode and countries led by the United Kingdom and Russia have vigorously developed the aircraft carrier fighter take-off mode of glide jump take-off + vertical/short-range fighter, and the sliding jump take-off + rocket boost, which seemed to be a perfect solution to the take-off problem of aircraft carriers and carrier-based aircraft at that time, has been forgotten in the corner of history.
But this kind of technology has been forgotten, not to say that this kind of technology is not good, now think about it, rocket technology has been developed for so many years, compared with the rocket technology in the fifties and sixties, the current rocket technology has undergone earth-shaking changes in terms of stability, reliability and thrust, compared with the rocket technology in the fifties and sixties, it is absolutely incomparable
Over the years, a large number of fighter jets equipped with rocket boosters have also been carried out in China, and a lot of key data have been obtained.
Seeing that Zhang Lan fell into deep thought, Hu Ruoxi gently twisted the corners of her clothes and carefully observed Zhang Lan's expression, for this girl, this method is the only low-cost solution to the problem of carrier-based aircraft combat effectiveness that she has thought of since she recently paid attention to the aircraft carrier issue, and originally wanted to use it to ask Zhang Lan for credit, but now looking at Zhang Lan's contemplation, her heart is naturally nervous, suffering from gains and losses, lest the idea she worked so hard to come up with will be vetoed by Zhang Lan.
"Yes" After a long time, Zhang Lan let out a long breath, nodded, and said to Hu Ruoxi, "This method is a good way."
"Is it really a good idea?" Hu Ruoxi's eyes suddenly lit up, and the whole person's little face instantly became radiant, like a peony that suddenly bloomed, delicate and dazzling
"Of course" Zhang Lan nodded with a smile, touching Hu Ruoxi's little head, "When did I lie to you?" ”
"Yes, hehe......" Hu Ruoxi glanced at Zhang Lan beautifully, lowered her head and smiled shyly: I am not useless, I can still help Zhang Lan's brother a lot.
"But I think there's a better, simpler solution." Zhang Lan hesitated for a moment and said to Hu Ruoxi.
Originally, this guy didn't plan to say it to Hu Ruoxi, for fear of being angry with this girl, but think about it, with so many years of mutual understanding between the two of them, will this girl still misunderstand herself? The idea I had just now was purely to scare myself.
Sure enough, hearing that Zhang Lan was such a girl, she suddenly became energetic, and her spirits lifted, and she grabbed Zhang Lan's hand and asked Zhang Lan anxiously, "Brother Zhang Lan, what can you do?" ”
"The solution is that if the high-thrust aviation jet engine fueled by hydrogen produced by the Alice Group itself is replaced, it can perfectly solve the problem that the carrier-based aircraft called by the glide jump take-off cannot take off with full fuel and fuel. Not only can this problem be solved, but if you replace it with your own company's hydrogen-fueled aviation jet engine, you can carry more fuel and weapons. ”,
"Your company's jet aero engines? Does your company have this kind of engine? Hu Ruoxi frowned, a little puzzled by Zhang Lan's words.
"Of course there is," Zhang Lan touched her nose, a little depressed, what her company produces, this girl doesn't remember? I couldn't help but remind the girl, "You forgot, the two ultra-large thrust-to-weight jet engines used in the four engines used in our Alice Group's aerospace aircraft were developed by ourselves, and when we were at the Singapore Air Show that year, we also exhibited several jet aero engines with thrust-to-weight ratios of more than 12." ”
"Oh, how did I forget about this," Hu Ruoxi said lightly, stuck out his tongue, and looked embarrassed.
I think that at the beginning, when I saw the high-performance aero engine developed by the Alice Group on the news, I was very happy for them and for this country for a while, this is the most advanced military aero engine developed by our country, the thrust is the most advanced military aero engine developed by our country, if it is installed on our country's fighter jets, wouldn't it be equivalent to giving these eagles flying in the blue sky a more powerful heart?
But then this matter slowly disappeared, and I slowly forgot about it.
Saying this, the little girl looked up at Zhang Lan with a proud face...... For Zhang Lan's family company to be able to make such an advanced thing, I am sincerely proud of Zhang Lan, "If you replace such an engine, then you really don't have to worry about the take-off method, even if it is an ordinary taxi, it can take off with full fuel and full load." ”
"It's not more," Zhang Lan said with a smile, reminding this girl by the way, Zhang Lan can see it, if you don't remind this girl, this girl is a typical little confused, "Have you forgotten our Alice Group's tiltrotors?" Is it the one that has a three-section wing and the main wing is a forward-swept wing? At that time, the early warning planes, anti-submarine planes, air tankers, transport helicopters, and other aircraft carried by the aircraft carrier, except for carrier-based fighters for direct combat use, can also be replaced by a series of tiltrotor aircraft produced by their own group. ”
"Yes, yes," Hu Ruoxi slapped his face with sudden realization and excitement, "This is a good way, compared with ordinary helicopters and subsonic fixed-wing aircraft, the comprehensive performance of your tiltrotor is much stronger than them."
"For the tiltrotor that can take off and land vertically like an ordinary helicopter, and can take off with a short-distance taxi like a fixed-wing aircraft, even if it takes off by a taxi, the runway length required is only 150 meters, and the runway on the aircraft carrier also has a 200-meter factory, which can fully meet the requirements of the tiltrotor taxiing and taking off, and the take-off distance of 150 meters is increased by nearly 80%. It is really a good deal, and compared with other types of auxiliary aircraft used on US aircraft carriers, these aircraft are more flexible in their combat methods, and their speed is natural, and their combat efficiency is also higher."
Of course, compared with the ordinary rotor helicopter that can only be given a speed of 260 km/h - 280 km / h per hour for cruising flight, and the maximum flight distance is only about 800 km - 900 km, the tiltrotor designed by Alice Group with a short run-off mode can not only reach nearly 900 km/h of cruising time because of the unique three-stage wing and the structure of the main wing as the forward-swept wing. It has reached the speed limit of the aircraft that uses the power propulsion of the rotary propeller fan, and the maximum range can reach more than 3,500 kilometers.
There is a greater advantage that if it is equipped with a variety of auxiliary aircraft, the logistics maintenance and support of the aircraft, and the maintenance are relatively more troublesome, on the contrary, if different application models are developed on the basis of the same aircraft, the logistics support and maintenance efficiency of the aircraft will be greatly improved, which is another benefit
Some time ago, there was a heated discussion among netizens on the Internet who were concerned about the military, because they did not know that the Alice Group already had such advanced equipment, and still less did they know that the Alice Group had already begun to help the military develop the AI-20 tiltrotor with a maximum load capacity of 20 tons when the AI-10 tiltrotor with a load capacity of 10 tons came out
"A 10-ton tiltrotor can be converted into an air early warning/command aircraft, electronic warfare aircraft, anti-submarine aircraft, emergency life-saving aircraft, and transport aircraft, and a 20-ton tiltrotor can be converted into an air tanker" The little girl counted one by one with her fingers, because she was too surprised, a little face was already red with excitement, and the ruddy little mouth had opened slightly, revealing white teeth, like ripe cherries, so that Zhang Lan couldn't help but move her index finger and wanted to go up and take a bite,
It's not that I don't know, after careful calculation, I found that with the support of Alice Group, China has achieved such a huge advantage
Zhang Lan smiled, this girl has not yet calculated, after the extra-large outward through deck amphibious assault ship built by the Alice Group for the military was put into service, the various transport aircraft and combat aircraft used on this extra-large outward through overtime amphibious assault ship are also all kinds of transport and combat-type tiltrotors under development of the Alice Group - of course, now this news is top secret, and it is not surprising that this girl does not know.
In addition, if the AI-20 tiltrotor is converted into an aircraft carrier-based air tanker, although the 20-ton fuel load cannot be compared with the 68-ton full load capacity of the KC-135 "Stratotanker" air tanker used by the United States, it is still quite acceptable compared with the 30-ton air fuel load of the US KC-130F air tanker. More than 10 tons of fuel is used for the tankers themselves, and less than 20 tons are used for in-flight refueling.
However, the AI-20 tiltrotor of the Alice Group is different, this aircraft itself uses hydrogen fuel cell power, which does not consume the amount of fuel carried by the aircraft itself, and the amount of fuel that can be used for air refueling is higher than that of the KC-130F air tanker in the United States.
Considering the number of fighters carried on an aircraft carrier, as long as there are two AI-20 air tankers, it can fully meet the refueling requirements of the entire aircraft carrier fleet in wartime for combat aircraft and non-combat auxiliary aircraft
In addition, there is another key problem that must not be ignored is that even the United States does not have a large tanker plane of its own on the aircraft carrier, and if it needs to refuel in the air, it can only rely on the United States' military bases around the world to dispatch tankers to refuel the carrier-based aircraft fleet.
