How did the numbers of Chinese fighters come about?

Principles of numbering of Chinese fighters:

Numbering principle: Section. The first and fourth digits are the division number;

The second digit is the group number;

Clause. The three and five digits together are the machine number;

Old Numbering Principle:

If the first digit is even, the first digit does not change.

For example, this one: 12223.

The first thing to know is that it follows the old numbering principle:

Look at the division number is 1xx2x. The first digit is 1, 1-1=0;The fourth digit is 2, 2-1=1. Therefore, after the minus, it is 01, which means that the empty 1st division.

Look at the digit number is xx2x3, and the three and five digits together are 23, which means the 23rd machine.

So this 12223 represents the No. 23 machine of the 2nd Regiment of the 1st Air Division (check the table on the 1st floor: the first digit is 1, and 1 is found in the gray vertical row of the figure; The 4th digit is 2, and if 2 is found in the green horizontal line of the figure, then the staggered display of the two is empty 1 division).

Another way to do this is to hard back:

On the left is the number of the first four digits combined, and on the right is the corresponding division, where y=x-1

Old Numbering Principle:

1x=0y division.

2x=2y division.

3x=1y division.

4x=4y division.

5x=3y division.

The new numbering principle is relatively simple and easy to remember:

Sum up the four digits and subtract 11.

For example, the fighters in these two pictures are numbered according to the new numbering principle:

The number of the J-8D is 2 0, the first digit is 20 together, and 20 minus 11 is equal to 9, which means that it is the 9th division of the air.

Chinese fighter jets, officially known as fighter aircraft, are marked with the word "J", similar to the United States with the initial letter "F" of fighter fighters, and the suffix is numbered by the model number, such as J.

Fifth, annihilation. Sixth, annihilation.

7. Annihilation. 8. Annihilation.

10. J-11 and so on.

Throughout the history of military development in New China, there is a question that has always puzzled many military fans: why did our fighter number start from J-5? Is it just a casual start?

There are rules, yes, the J13 was originally the successor to the J-6, and it was originally considered to be a single-engine light aircraft, requiring performance stronger than the MiG-23, close to the F16, designed by the 601 Institute, and defeated the J-10 program of the 611 Institute in the review stage.

When this scheme is rejected, the number is deprecated. The machine was originally at the design stage, and no prototype was built.

J14 is also 601 as the leading, engaged in a twin-engine heavy machine scheme, the original design requirements are close to F15, SU27, and J10 to form a high and low match, but after the introduction of SU27 production line, the plan was abandoned, and the number was abandoned accordingly.

As for the so-called J31, it is actually misinformation, his number is 31001, which is a project established by Shen Fei with the support of AVIC, the project code is Project 310, and the number indicates that this is the prototype of Project 310 No. 01. The aircraft did not get the first project, pay attention to the tail of the plane can be found, there is no August 1st military emblem on it, only a logo similar to carved soap, which shows that this thing is purely a black account, no air force number.

The current approximate pattern of the Air Force numbering is as follows: the fourth-generation aircraft will be numbered with J20, and the previous third-generation aircraft will continue to use the existing serial number.

This is a requirement for secrecy, and there is the fact that there were prototypes but did not survive. It's like f22 vs. yf23, f35 vs. x32. The degree of advancement is not calculated according to the number, otherwise wouldn't the F104 be much more advanced than the F22?

The J-13 and J-14 had before, and they were fourth-generation aircraft schemes, which were on the drawings, and later abandoned, evolving into the current J-20 and 31001 demonstrators.

There must be, but it has not been successfully developed or is being developed.

Qiang-5 "Fantan" fantan

J-8 "Fin Whale" Finback

Flying leopard "Flounder" flounder

J-10 Firefly

J-20 "Fire Fang" Fire Fang

According to NATO standards, each code name is an English word that starts with an F. For example, strong -5 bantan = fantan. Other aircraft used by our army, such as J-7 and J-11, are considered by NATO to not be original designs of our country.

The number given by NATO to the MiG-21 and Su-27 is retained. Same words starting with f. MiG-21 "Fish Nest" Su-27 "Flanker".

"J" - fighter "strong" - strong attack aircraft "boom" - bomber "fighter bomb" - fighter bomber "J teaching aircraft" - training aircraft "bomb oil" - tanker "straight" - *** "Wuzhi" - armed *** In addition, there are purchased Su 27, Su 30, export FC - 1 "Thunder" L-15 training aircraft, etc.

Fighter plane, we call it a fighter plane, so it is called J, such as J-10, attack aircraft we call a strong attack aircraft, Qiang-5, and a bomb fighter is the first word boom.

The letters are capitalized in the first letter of Hanyu Pinyin, and the following numbers are before and after the development task.

What type is named after the first word of the type plus a model!

J-(fighter), J-5 (fighter), H-6 (bomber), Y-6 (transport), Straight (***), Air Police (AWACS), H-6 (air tanker), in addition to the Russian-made Su-(fighter), Mi (***), Ka (anti-submarine), Il-76 (transport), Il-78 (air tanker) ......

The first letter of the aircraft class name or the first letter of pinyin + model.

1.Fighter aircraft, "J" plus serial number, code name for Chinese pinyin letters plus serial number, such as J-5 (J5), J-6 (J6), J-7 (J7), J-8-2 (J8-2), J-8-2M (J8-2M), J-10 (J10), J-10B, J-11 (J11), J-11B, J-11BS two-seat model 2Forceful attack machine, "strong" plus serial number, code for Chinese pinyin letters plus serial number, such as strong 5 (q5) 3

Bomber, "boom" plus serial number, code name for Chinese pinyin letters plus serial number, such as H-5 (H5), H-6 (H6), H-6D (H6D) 4Transport aircraft, "Yun" plus serial number, code for Chinese pinyin letters plus serial number, such as Yun 7 (Y7), Yun 8 (Y8) 5, "straight" plus serial number, code for the Chinese pinyin alphabet plus serial number, such as straight 8 (z8), straight 9 (z9), straight 10 (z10), armed ***, "straight" before adding "wu", such as wuzhi 9 (wz9), wuzhi 10 (wz10) 6

It's chickens, and cows will be used in the future.

Take the first letter of the first word.

For example: J-10 = J10
