Chapter 942: Stall spin (1)

The next day, the sky lighted up.
On the second day of the Niu State inspection group in Han State, they participated in a scientific research test flight in Han State together, and the stall tail of the JH 7-belt bomb was recovered.
Stall spin is a terrible flying accident.
Flight is beautiful, but danger is always there. From the day the airplane was born, the danger has always existed. In all kinds of flying accidents, the stall and spin is definitely the most terrible one, from the birth of the airplane. From then on to later lives, this is a terrible demon.
Stall and spin are actually two categories.
Stalling is a phenomenon that occurs when the airflow on the upper surface of the wing separates when the angle of attack of the aircraft increases to a certain degree, resulting in a decrease in lift.
An airplane flying in the sky is balanced by lift and gravity. Lift is generated by the airplane's wings. If the angle of attack is too large, the lift will be insufficient and the airplane will fall.
At this time, the aircraft will lower its head and sink until it gains enough lift to fly.
Therefore, if the speed is only a stall, if the altitude is sufficient, the speed will increase if the plane falls down, and when the speed is sufficient, you can slowly pull the lever backward to recover to level flight.
A stall does not necessarily enter a tail spin, but the tail spin must be in a stalled state, and it is also a very special kind of stall, that is, when one wing stalls before the other wing, the aircraft will move toward the side that stalled first. The direction of the wing rotates along the longitudinal axis of the aircraft, which is called a helix or spin.
At this time, the aircraft will suddenly lose control, falling down while turning sideways. In many cases, it is the result of invalid control and crashes.
Stall spin is a very terrible flight accident for aircraft.
In the previous airplanes, the designer did not think about how to solve it, and the pilots did not try. Once they accidentally stall and spin, there is only one kind of parachuting.
If the height is not enough, you will fall to death.
Now, newly developed airplanes are required to be able to be corrected when they enter a stall spin. This requires test pilots to venture in and then change them out.
Historically, the flying leopard’s stall spin was tested with human lives. The flying heroes sprinkled blood in the sky and found a way for future generations to recover. They were all heroes of the Han Kingdom.
Now, it's different.
The information Qin Guan found was very detailed. In addition to directly transitioning JH VII to JH VIIA, the various test flight data were also clear. Otherwise, how could they complete the test flight so quickly? Just go through the process according to the data.
The stall spin has been flew twice, and they have successfully recovered, but now it is the stall spin recovery with bullets.
Because the plane is to fight.
After the aircraft is loaded with bombs, the aerodynamics will change, and the operational characteristics of the aircraft will also change. Therefore, in many cases, the operation with bombs will be slower.
Just using an empty plane to do a test flight cannot be close to the actual situation. The fighter plane is in combat and enters the tail spin with the bomb. How to make it out?
This requires experiments to know, even after the missile enters the tail spin, will the wing be torn by the weight of the missile? These are unknown.
Therefore, this test flight is actually risky.
There is a risk, I will go first! This is Chen Rui's criterion. He doesn't know how many difficult subjects he has flown. He is the first one to go first every time. He has the most experience in flying and is the most respected. Aircraft designers trust him.
Wearing a flight suit, Chen Rui stepped onto the seat, and in the back seat, Kaili also went up.
This test flight was approved by superiors.
Chen Rui doesn't have such great power. If he wants to fly with foreigners, he can fly? Of course not.
This test flight is full of risks, but risks and benefits coexist. There are so many experts in the country, that will definitely be publicized.
Which aircraft company dared to stall and spin when testing a fighter plane? After doing it, dare to do another flight test with bombs?
Our flight test process is the most standard and perfect. Buying our aircraft is the most secure!
As long as the test flight is completed, even JH 7 will be labeled with a resounding label.
In this era, stall spin is the most terrible. In later generations, when the Han Guo Air Force uses K-8 for flight training, it will conduct stall spin recovery training. Only by continuously strengthening flight training can it To win the actual battle, you cannot do all kinds of risky maneuvers for safety.
(In fact, it is called Jiao-8 in China, and the export model is K-8, but everyone is familiar with K-8, so I call it that.)
After a night's rest, Chen Rui was radiant again, and it was true that the emperor was not in a hurry.
Chen Rui didn't think about feelings at all. It was fun to talk to Kaili. It was an exchange between peers. As for Lin Xiaoxia's feelings, Chen Rui was even Daha. Therefore, when I came back last night, I slept very well. I was not affected at all, but I am in a very good spirit today.
Qin Guan was also speechless.
A crowd of people are waiting in the airport, flying tails, of course they will not fly over the airport, they can only listen to this process via radio.
With Kaili's participation, Han will not make fakes.
"If you have concerns, you don't need to participate." Chen Rui said to Kaili, who was climbing the gangway behind him when he lay down on the gangway and stepped onto the plane.
"I have bought an insurance, three million cattle pounds." Kaili said: "Beneficiary, it's your name."
Chen Rui shook his head repeatedly, what's the use? If you are gone, then I am definitely gone, what good is it for me to benefit? Besides, money is not important to me at all. I am not living for money, so tired.
Stepping into the cockpit, the cockpit cover slowly closed, and with the roar of the Spey engine coming from the tail, the fighter slowly slid onto the runway.
Two models of C801 missiles were mounted on the pylons inside the wings.
Of course it is not a real missile. It will only be mounted during combat. Although the current model is a model, its size and weight are the same.
But on the outer pylon of the wingtip, there are still two models of short-range missiles. If you are interested, you can see that the model of this missile is the Pili-8.
Since it is called a fighter bomber, it is of course capable of self-defense. This self-defense is achieved through the short-range missiles it carries, and it can be used at critical times.
In fact, according to the current technological development of Han, it is also possible to integrate the imitating Sky Flash missile, but there is not much necessary. Its mission is to attack the sea. In case of a blow, it is enough to have a self-defense method Up. The Thunderbolt-8, also known as Weird Snake-3, has the same weapon interface as the Rattlesnake. After export, it can be replaced with AIM-9L at any time according to foreign needs.
After the afterburner was turned on, the JH-7 fighter took off from the runway, and Chen Rui's test flight finally began.
Kelly in the back seat also looked at the various meter data in front of her very seriously. She was responsible for recording.
