Coquettish Rebirth

After blowing the wind tunnel and returning home, Jia Hongjian still didn't know what the idea was in his mind.So after dinner, Jia Hongjian went to the study and turned on the computer, and began to search for various materials and videos related to cars on the Internet to stimulate his own inspiration, to see if he could be inspired to find such an idea!However, when he opened the browser and began to look for videos related to the car, he saw a piece of news—an F-18 Hornet fighter jet of the US Navy crashed in California and crashed into a house, causing a house and a building to die. Two cars are on fire!

Originally, this matter seemed to have nothing to do with Jia Hongjian, but don't forget that we have a house in California!What if it hit Beverly Hills?What if it hit our house?At that time, Jia Hongjian hurriedly clicked on such a news, which was reposted in China, and it was quite vague. It just said that the F18 fighter jet broke down during routine training in southern California. The pilot ejected to escape, and then the plane crashed into the Residential area!your sister!At that time, Jia Hongjian wanted to scold her, but Los Angeles is in southern California!You say this pilot, don't say that you have to learn from your Chinese counterparts to protect the lives and property of the masses even if they sacrifice their lives. At least you should steer the plane a little bit away before ejecting and escaping, okay?Don't worry about escaping by yourself, no matter whether the plane turns around and hits the people's house, okay?It's fine if your sister's house is simply destroyed, what if the family is at home?At that time, wouldn't someone suddenly bring disaster from the sky?Who did they provoke?

At that time, Jia Hongjian looked at the time and estimated that it was past 7:100 in the morning on the west coast of the United States. He hurriedly made an overseas call to a familiar congressman in Los Angeles.As a result, after a phone call, I found out that it was not Los Angeles that the fighter jet hit, but San Diego, a "small town" south of Los Angeles!There are more than 300 million people in the urban area of ​​San Diego, and a total of more than 18 million people in the Greater San Diego area.It is the second largest city in California, and this city also has a military port on the Pacific Ocean!The US Navy is basically stationed in San Diego on the west coast!Thinking of this, Jia Hongjian immediately understood, no wonder it was the F18 of the US Navy!Isn't the navy's f[-] training flying around San Diego?

Thinking of this, Jia Hongjian heaved a sigh of relief, how can he say that his house was bought for tens of millions of dollars?Even if you are insured, the insurance company can pay you if you get hit.But what a problem!Later, he went to the United States, but there was no house on the west coast. The clothes in his house, Ye Jing's jewelry, and all kinds of data in the home server were all destroyed. Is it really painful?At this time, he really felt that our domestic air force pilots and navy pilots praised it!Our domestic pilots often prefer to give up the chance of escape in order not to hit residential buildings!Compared with the United States, this kind of fearless spirit is like heaven and earth!Jia Hongjian felt that there must be a labor activity or something to express the hearts of the people to the pilots.

When his thoughts diverged, Jia Hongjian still stared at the picture of f18 flying on the screen as a data map, and then looked at it.He suddenly thought of one thing - the design of the nose of the plane, isn't that very particular about the aerodynamic shape? F18 and other fighter jets are all made of a conical nose, which we can’t learn, after all, it’s too weird for a car to have a conical nose.But... the nose of the f22 is not conical! In order to reduce the radar reflection area, the nose of the f22 was made into a diamond-like design.There is an obvious edge on the left and right sides of the nose!So can our front of the car learn from the design elements of the nose of a fighter like f22?

Of course, now that we are referring to design elements, it does not mean that Jia Hongjian will tell the people below that we have to change the design again.It doesn't mean to copy the front of the car directly like the f22 - it is definitely impossible to copy the front of the car directly, after all, our car still needs a place to install the headlights.If the nose of the f22 is completely copied, the bumper is as sharp as a blade, and the whole nose is raised like a half-cone shape, where should we install the headlights?If the headlights are turned up from the car body like the previous sports car, then the aerodynamics will definitely be affected!So it is a reference, not a copy.It just absorbed some elements and concepts of other people's f22 nose design!

Thinking about it, Jia Hongjian took out a pen and paper to draw a sketch.In his sketches, the bumper of the car was changed a bit, and became a design that was still long but with a semicircular surface.This bumper is very wide.If it is parked head-to-head with an ordinary car, then the top of the bumper can reach the top of the air intake of an ordinary car!At the same time, the semi-circular design can play a certain role as a "shroud", that is, to separate the incoming air.In fact, such a "bumper" is not a real bumper. The real bumper is an I-shaped aluminum alloy profile hidden behind it, and the outer arc is made of metal that is relatively easy to deform. The pure air deflector made of leather is used to separate the airflow, and it is also in line with the design of modern high-end cars to reduce injuries to pedestrians.

Like a missile or a traditional artillery shell, there is something like a curved cone on the head. Such a thing is so small that the shell is called a hood, and the rocket on the missile is called a shroud. To put it bluntly, it is used to separate the air. of.As for the car, Jia Hongjian doesn't know if the effect of designing a fairing like this is good, at least it looks pretty good, and it has a sci-fi design style-in other words, anyway, the visual effect is good, so as long as This fairing can be used without damaging the aerodynamics, right?And on the other hand, Jia Hongjian thinks that this kind of arc fairing is better than the flat bumper of other SUVs, right?There are also many suvs whose bumpers are deliberately made with a large plastic shell on the outside, just to look mighty and domineering, but the impact on aerodynamics is definitely not small!

At the same time, such a long bumper, if you look down from the air, the bumper is not completely straight.It's just that there is a small section in the middle of the front of the car that is straight, about the width of the license plate, and then slightly inwards on both sides, and then at the center of the front of the car and the distance between the wheels on both sides, a larger angle is made. inward sloping.Why did Jia Hongjian make such a design?Because in order to match the hood of the car he made again!Moreover, the bumpers of ordinary cars are not horizontal and vertical. The design of modern new cars is basically that the position of the air intake in the front of the car is relatively flat, and the bumpers near the wheels are bent inward to a certain extent.

And Jia Hongjian's design can make the front of the car look more curved, which is more conducive to rectification!It can better guide the airflow coming from the front of the car to the left and right sides of the car!But why not make it into an arc?Because the engineering difficulty of making such a chamfer is lower, it can save money!We make products to choose a compromise between effect and cost!After the bumper is designed in this way, the design of the front hood has of course also undergone some changes.The hood of this car also has several twists and turns corresponding to the bumper design—the hood design of this car obviously also has several edges, and the two corners of the bumper at the position of the license plate on the front correspond to the two hoods on the edge.When this edge extends upwards, it also spreads to the left and right, and finally reaches the position of the driver's right hand and the co-pilot's left hand.The two corners of the front bumper between the license plate and the wheels on both sides correspond to the other two edges on the front cover. These two edges go up and to the sides, which are exactly the dividing line between the top and the side of the car!

What is such a design for?Just to imitate the design of fighter jets!For example, in Jia Hongjian's impression of our Chinese stealth fighter J-20, the lower part of the nose is not simply arc-shaped, but has ribs like the hood of our car!After having such ribs, you can make a small arc on the car shell in the middle of each rib, and then you can make the whole car look sci-fi while maintaining a certain excellent aerodynamic shape, right?For example, the front part of the fender near the front wheel is also made into a forward concave state, so that the front of the car can cover a part of the front.In this way, the airflow that hits from the front will also be diverted to the sides in advance, which is definitely better than the previous horizontal and vertical design!

The design of the front of the car alone is said to be based on the design of the stealth fighter, and everyone will definitely believe it!Because this kind of design has never been made by others!Even for all kinds of high-end sports cars, their shapes are as round as possible, there is no such sharp edges and corners!It is even estimated that if Jia Hongjian did not mention what aircraft he borrowed, some people might think of the first generation stealth fighter F-117!The f117 is designed with various corners and corners all over the body. The corners and corners are designed to reduce the radar detectable area!

Having said that, after redesigning the front of the car, the airflow hitting the front of the car body will be divided into several parts, one part will be diverted and hit the windshield, and the other part will be directly diverted to the sides and flow along the sides of the car body. Pass.If you just look at the airflow hitting the windshield, it will still start to disperse at the highest point of the roof above the driver's head. After all, the highest point of the car will start to drop at this time.Even if it descends to the rear of the car with an arc, and even created a rear door like a "trunk compartment", Jia Hongjian reckons that if such a design is used to blow the air, there will still be some airflow at the rear of the car. shake.So is there any way to keep the airflow from shaking?If the airflow does not shake, then the eddy current behind the car will be small, and the resistance will be small!Jia Hongjian felt that he didn't believe that he was the only one in the car design world who wanted to solve the problem of the vortex vacuum zone at the rear of the car!So what is the solution for others?
