Chapter 930: Windfall

Although a lot of people had swarmed in just now, they were still empty on the deck after being scattered into such a large ship. The sea breeze in early summer brought up layers of waves, gently swaying the body of this steel behemoth, and Tan Zhenhua also followed the slight ups and downs, wandering around on the empty deck.
And when he walked randomly to the middle of the ship, a large metal frame protruding outward from the port side attracted his attention.
this is……
There was a burst of ecstasy in his heart, and he quickly ran over to observe carefully, and saw that several rows of red, green and green headlights were installed on the shelf, which looked like traffic lights in the city.
"Ah~~~ha! A windfall is coming!"
He couldn't help but screamed up to the sky, and hearing his shout, Zhang Shaozhong and Zhu Yingfu also ran over quickly, and surrounded them to see what kind of baby could make the second son so excited.
Just one glance, these two experts also suddenly gave out a long roar of excitement just like Tan Zhenhua—
"Fresnel lens, it is Fresnel lens!"
"Good baby, I did not expect such a good baby left in this broken ship!"
The three looked at each other, and they all saw the inexplicable surprise from each other's faces. Tan Zhenhua already yelled impatiently: "Lao Zhu, are there any reliable fitters and master electricians on board? Hurry up, take them down. Put it away!"
"Yes, yes, yes, I'm going to get someone to come." Zhu Yingfu didn't care about any demeanor, and turned around and ran, while Tan Zhenhua and Zhang Shaozhong kept spinning around the metal frame with greed in their eyes. The light seems to have a hook...
Some students are about to ask, what exactly is this Fresnel lens? Why can the knowledgeable second son and naval weapons expert Zhang Shaozhong be so ghoulish?
Because these small rows of lights are too important for aircraft carriers.
As we all know, most aircraft carriers are actually quite weak in terms of the weapon systems installed on their hulls. Most aircraft carriers only install a few close defense systems for self-defense. When going out, you must There must be a large destroyer fleet to provide medium and long-range air defense and anti-submarine capabilities, and at least 1-2 attack nuclear submarines must be arranged underwater. Its combat effectiveness is completely reflected by the carrier-based fighter jets on it. of.
Oh, Soviet Russia’s ingenious "aircraft cruiser" is not in this list, it is completely heresy.
In other words, the number of fighters on an aircraft carrier, the performance of the fighters, and the launch of the carrier—the ability to recover fighters are the criteria for measuring the combat effectiveness of an aircraft carrier.
But after all, an aircraft carrier is different from a land airport. No matter how large it can be built, the deck space on it is limited. Regardless of its length or width, the runway that can be left for aircraft to take off and land is so small.
To take off and landing fighter jets on the bumpy sea, at such a point in length and width, and still on a bumpy runway, undoubtedly puts forward extremely high requirements on pilots' takeoff and landing skills.
Compared with take-off, landing is more difficult.
Not to mention anything else, just aiming at the aircraft carrier runway in the vast ocean that looks not much bigger than a stamp is a difficult maneuver that tests pilots’ skills, patience and courage.
Therefore, in order to help the pilots land safely on the aircraft carrier to the greatest extent, Lieutenant Colonel Gerhardt of the British Navy was inspired by the action of his female secretary putting on lipstick in the mirror, and designed the earliest optical landing aid device Descending mirror.
It is a large-curvature reflector. The light located at the stern of the ship is directed to the mirror and then reflected into the air. It provides the pilot with a descending with an angle of 3.5 to 4 degrees between the light and the sea level. The pilot follows this and The position of the aircraft in the mirror is corrected until it makes a safe landing.
However, this kind of optical descending mirror can only work to a certain extent and brings new problems: the hull of the aircraft carrier will heave and sway due to the undulations of sea waves, and the light emitted by the mirror is very unstable, so It is still inevitable that accidents happen from time to time.
In the 1960s, the Britons combined the most advanced optical, mechanical and electronic engineering technologies, and invented a more advanced "Fresnel" lens optical assisted drop system, which is similar in principle to an assisted drop lens and is also provided in the air A light gliding surface, but with the blessing of advanced technology, the signal provided this time has the ability to self-correct within a certain range, and uses multiple colors of lights to prompt the pilot to continue descent, correct deviation or go around. , It is more conducive to the pilot to judge the position and correct errors. Since the Americans formally installed the first "Fresnel" lens optical assist landing system on the "Franklin" aircraft carrier in 1960, this system has become the standard configuration of the aircraft carrier.
So, don’t look at this set of lights as just a few rows of lights. They are very similar to ordinary traffic lights. They look very simple, but in fact they are real high-tech products and one of the important guarantee equipment for the combat effectiveness of aircraft carriers.
And such an important thing, the Austrians actually forgot to remove it!
Or, it may be that the Ozhou people who have no aircraft carrier manufacturing capacity did not realize the importance of this equipment at all.
But whatever the reason for him, in short, meeting is predestined, you can't miss it when you pass by, the world's treasures are only for the virtues...cough cough cough cough.
After thinking about it, Zhu Yingfu had already returned with a few master workers. Several people circled the "Fresnel" lens optical descent system. After discussing with each other for a while, they moved their hands. Tan Zhenhua After yelling a few nonsense such as "Be careful not to be broken", the masters who were impatient and disliked him were blasted aside...
Seeing that all the attention of Zhang Shaozhong and Zhu Yingfu at this time was attracted by the "Fresnel" lens that was accidentally discovered, Tan Zhenhua not only couldn't get his hands in, but was also disgusted by others, so he could only muttered and protested in a depressed manner: "This is still me. The first one to find out!" After that, alone, he continued his stroll.
After just wandering around for a while, I have already "picked up" such a good thing. In this way, this boat can't be simply described as "the empty shell of broken copper and iron". There must be a lot of good treasures in the dozens of decks and more than a thousand cabins—and even if there is no such treasure as the "Fresnel" lens anymore, the hull itself, There is also the material for making this shell, which is very worthy of serious study.
Unfortunately, after 6 months, this significant hull will disappear from the physical level. At most, some photos and recordings can be saved, and even the drawings may not be retained...
No, drawings, surveying and mapping, time, why do you always feel as if you are thinking of something?
