After turning the fifth page, Zhou Hai turned to the sixth page and looked at the avant-garde and impactful concept drawing of a fighter plane. He was stunned and a little surprised.
"The forward-swept wing model is the true fifth-generation aircraft standard. It is my favorite style. It is my vision for future fighter aircraft. The aerodynamic efficiency and performance of the forward-swept wing model far exceed the central lifting body aerodynamic layout of the Su-27 series. After Europe and the United States, Swept wings, conventional airfoils, and my country’s canard + delta wing are the most aerodynamically efficient airfoils in aerodynamics and aviation history.”
Zuo Xue slowly introduced: "This concept aircraft simply uses a layout of forward swept wings and cambered double vertical tails. I haven't conceived the rest yet."
"It seems that forward-swept wings are not conducive to stealth, right?" Zhou Hai stared at the three views of this simple forward-swept wing concept aircraft, thought for a while, and expressed his inner thoughts.
Forward-swept wing, this wing is the most aerodynamically efficient airfoil discovered by mankind at this stage. It is different from the mainstream swept wings used in second-generation and third-generation aircraft. It presents a V-shape and has extremely excellent performance. It is very important for maneuverability and comprehensiveness. The performance improvement is extremely high, and a large number of airfoils such as swept wings can be rubbed against the ground.
Yes, just press and rub it to make it unable to move!
Firstly, the forward-swept wing has statically unstable aerodynamic characteristics, which meets the needs of high maneuverability of fighter aircraft. Secondly, due to its extremely high aerodynamic efficiency, the effective load capacity is increased by at least 30%, which increases the fuel capacity and bomb load capacity, and greatly improves the fighter aircraft's maneuverability. Low altitude and low speed flight performance.
The increase in fuel volume means that the combat radius and range are increased, touching the most critical performance indicators of a fighter jet!
Forward-swept wing models can increase the fighter's combat radius and range by as much as 40%.
If the combat radius of a swept-wing aircraft is 1,500 kilometers, then the combat radius of a forward-swept wing fighter can reach 2,100 kilometers.
Needless to say, the bomb load capacity involves the core combat effectiveness of the fighter aircraft. The higher the better, a 30% increase in data. If used solely for the bomb load capacity, it means that 10 tons will become 13 tons.
In addition to these two advantages, the forward-swept wing provides extremely high maneuverability. The canard wing aerodynamic layout currently in service in various countries cannot compete with it. It can greatly shorten the rolling distance for takeoff and landing, with a reduction percentage of 38%, instantaneously. The hovering angular speed can be increased by 20%.
If the J-10D Fire Dragon changes the main delta wing surface to a forward-swept wing, the 290-meter rolling distance of the normal air superiority weapon mounting scheme can be shortened to 180 meters.
However, due to various defects and technical problems, the forward-swept wing, which has great advantages, was not widely used in the third-generation aircraft era. In the era of emphasizing the stealth of the fourth-generation aircraft, the forward-swept wing, which is not conducive to stealth at all, was abandoned again. .
"The forward-swept wing is my vision for future air combat, where maneuverability is king. In future air combat, is there a possibility that both sides will have stealth fighters, thus canceling each other out..." Zuo Xue rubbed his hands. With his dazed forehead, he gathered his thoughts and expressed his thoughts on forward-swept wings and future air combat.
"Shh!" At this moment, Zhou Hai frowned, closed the exquisite album, interrupted Zuo Xue's words, and signaled to be silent.
Zuo Xue was stunned. Her sense of confidentiality made her instinctively stop talking. She looked at Zhou Hai with some doubts.
what happened?
Zhou Hai did not speak. His keen hearing detected abnormal movements. Heavy and numerous footsteps came from the corridor outside the hotel door, gradually approaching room 306.
silence.
There was a deathly silence in the room.
Soon, the footsteps and slight movements disappeared at the door.
Disappeared, or came specifically for Room 306.
"Sit tight and I'll deal with it. If something happens, you hide under the bed immediately." Zhou Hai's eyes narrowed with a cold light. He stood up and took out the Type 92 military pistol he was not carrying from his backpack and placed it on his lower back.
Carry a gun with you and put safety first. This is the core rule of this vacation. However, when we went to dinner before, this guy Zhou Hai forgot it gracefully.
Zhou Hai didn't know who was outside the door.
However, there is always something wrong with getting a gun.
"Be careful." Zuo Xue was sober and nodded seriously, with a hint of worry in her eyes.
"Dong dong dong!"
As soon as Zhou Haigang walked to the door, the next second, there was a knock on the door of Room 306, with moderate intensity, loud and clear.
"Is there anyone inside?" Then, a strange female voice sounded with respect.
"have."
Zhou Hai glanced through the peephole of the door. Standing outside the door was a strange waitress wearing a Red Maple Hotel uniform. He replied thoughtfully.
This routine is very familiar, very practical, and interesting.
It seems that we encountered something legendary?
"Hello, sir, please open the door." The hotel attendant in front of the door said respectfully.
Zhou Hai looked calm, did not refuse, and opened the door casually.
"We are the people's police, squat down!"
The moment the door opened, the waitress quickly pushed it open, and the three policemen hiding on the right side of the door rushed out immediately. An older policeman with an older face and a police card shouted, and the other two showed arrogance, intending to directly He rushed into the room, and behind him there was a policeman holding a working body-worn camera to capture evidence.
The voice was loud and resounded through the narrow corridor.
"boom!"
However, before the words could be finished, the two young policemen who had gathered all their strength to rush into the room directly bumped into Zhou Hai, who was standing at the door of the room. Their chests hurt and they took two steps back in a daze.
Blocked!
How many times have I performed similar actions, but this time I was blocked by a man at the door!
The narrow door can only accommodate one person walking side by side.
Zhou Hai stood here like a majestic mountain, standing at the door, blocking the entrance and exit.
"Are you going to resist arrest? I am a people's policeman. I repeat it again, squat down and get out of the way, otherwise coercive measures will be taken!" Seeing the young-looking Zhou Hai motionless, blocking the door of the room, his face was about thirty-six or seventeen years old. The old policeman shouted with anger on his face.
"Hello, comrade police, I suggest you stay calm. I am an active soldier." Zhou Haifeng was calm and calm. He stood upright and was not angry at the old policeman's roar. He glanced at the confused and angry man. The young policeman, calm and natural in his voice, directly revealed his identity.
Pretending?
It doesn't exist, and it's not necessary. This is not the attitude to solve the problem.
"I'll say it again, squat right away... active duty soldier?" The old policeman, who was about to issue a final warning, suddenly stopped speaking after hearing Zhou Hai's words. He was stunned, a little at a loss, and his momentum and confidence were instantly annihilated.
what's the situation?
soldier?
Active duty military?
What's going on? His status suddenly changed to active duty soldier? !
As a local official policeman, he does not have the right to arrest active military personnel. The most he can do is ask for cooperation in the investigation. Note that this is a request, not a requirement.
