What is the difficulty of the fighter jet s in flight refueling training screen for the pilot?

When we see the news of in-flight refueling of fighter jets, many people will think, "Isn't it simple?" "You must know that any action will lead to a failure to refuel; For the Fighter Division, any slight shake will affect refueling, and in severe cases, it will also lead to the destruction of the refueling device, which is a very difficult and skillful act.

First, the sky is surrounded by space on all sides, and it is difficult to stabilize the aircraft without a fixed "foothold" When we see the fighter refueling in the air, many people will say that it is very sacred, after all, it seems to be an acrobatic special.

You must know that the biggest feature of in-flight refueling is that there is no support point, as a fighter division, you need to stabilize the entire aircraft and not run around; Many people may think that flying an airplane is easy, but when you feel the game airplane yourself, you will find that you can "crash in an instant". It is really not easy for the fighter division to refuel in the air, after all, they need to accurately control the aircraft to avoid serious sway of the aircraft and lead to refueling failure, after all, there are many uncertainties in the air.

Second, the changing wind direction and drag will cause the aircraft to miss the accurate refueling point mentioning the sky, we will all think of the unpredictable wind direction, any slight wind direction will cause the aircraft to deviate.

Compared with daily flights, in-flight refueling is not a child's play, but a difficult task; The Fighter Division needed to stabilize the entire aircraft and make sure that the refueling tubes could overlap each other, a process that seemed difficult enough. Not all fighter divisions can easily refuel in the air, but the existence of air refueling is the best service for fighters to use, which shows that the difficulty faced by the fighter division in air refueling is very strong, and any relaxation will lead to refueling failure.

For the pilot, in-flight refueling needs to maintain the smooth flight of the aircraft, and at the same time, it is necessary to accurately connect the fuel pipeline and the refueling aircraft, and at the same time, the change of wind direction and drag will make the aircraft difficult to control, and also test the pilot's eyesight, which can quickly find the refueling port.

The difficulty should be particularly high! Because now there are not too many countries that have mastered the technology of air refueling. Involving the precise docking of the oil port between the tanker and the fighter under the relative stationary conditions, the technical requirements for the pilot are particularly large.

It's very difficult, first of all, you have to get a good balance, because you are constantly moving forward, so you have to keep a good distance. The refueling of a fighter plane in the air involves a picture similar to the docking of two high-speed machines, which tests not only the skills of being a pilot, but also the cooperation and tacit understanding of two people.

Taking the tanker as a reference, the stationary of the fighter, the relative speed of the fighter is constant, the amount of fuel of the fighter is constantly increasing, the mass is increasing, and the kinetic energy is increasing The mass of the fighter is increasing, the height is unchanged, and the gravitational potential energy is increasing Mechanical energy = kinetic energy + potential energy, the fighter does not undergo elastic deformation, the kinetic energy increases, the mass potential energy increases, and the mechanical energy increases Therefore, A is wrong, B is wrong, C is wrong, D is correct.

Therefore, d

Taking the tanker as a reference, the stationary of the fighter, the relative speed of the fighter is unchanged, the fuel volume of the fighter is constantly increasing, the mass is increasing, and the kinetic energy of the unbased is increasing The pure mass of the fighter is increasing, the height is unchanged, and the gravitational potential energy is increasing Mechanical energy = kinetic energy + potential energy, the kinetic energy of the fighter is increased, the potential energy is increased, and the mechanical energy is increased Therefore, A is wrong to do the inspection of the shed, B is correct, C is wrong, D is wrong.

Therefore, b

After refueling, the fighter still flies at a constant speed at the original altitude and speed, the amount of fuel of the fighter increases, the mass increases, and the kinetic energy increases The mass of the fighter increases, the altitude does not change, and the gravitational potential energy increases Mechanical energy = kinetic energy + potential energy, the fighter does not undergo elastic silver deficiency deformation, and the elastic potential energy is not considered The kinetic energy increases, the gravitational potential energy increases, and the mechanical energy increases Therefore, a, b, c are wrong, and d is correct

Therefore, d
