First thing to say is that J -10 originally as the first self-developed fighter aircraft should be a very proud thing. Do not know why the most advanced online things are treated as final and ridicule .

I have the hair on a simple analysis of J -10 inlet , but also a little bit true colors F -10 .

First of all, J -10 is the third generation and a half , this is not against it . There is a third generation standard machine is highly mobile . The biggest one is the mobility when the stability of the high angle of attack . We look at the representatives of three generations of aircraft .





The two aircraft strake vortex , enhanced when the wing angle of attack in the lift , slowing the flow separation of the wing . Increased angle of attack aircraft state controllable.

The F- 10 then ?

No trim wing , but when the angle of attack aircraft controllability of various flight performance has been confirmed . Look at the figure above the wing of "smoke ", and no separation . Why?

Actually is because the J- 10, along with the head below the inlet on the " huge " gap . J- 10 here is the core of the Internet attack .

Here is actually a very clever design of J- 10 place . Now in addition to the DIS F-35 outside the inlet , are all discouraged slot . Main function is to head or body of the inlet boundary layer separation in the outside , so as not to interfere with the efficiency of the inlet . And this discouraged the actual tank does not need F- 10 so exaggerated . Fighter in the world , only the F- 10 is also designed so much discouraged trough boundary layer . Do not believe in their plans to go to search .

The role of F- 10 tank discouraging fact is the middle of the nose , and inlet airflow compressed by a certain point of introduction to , and the exhaust inlet on the edge of the window out of the inlet gate excess air mixture . This will air " Cuochu vortex "in the high angle of attack of the state, playing on the wing surface to improve the main wing angle of attack lift , and wing flow separation characteristics .


Why? We first look at the features, first look is crazy in the curse of the six -line " stick . " Carefully to see they have a point of view , if only to increase the strength , most point of the front of the Okanagan Why is the inside of it ? Do not have to flat it out . In fact, is to increase to discourage slot (or called pressure gas tank ) pressure , in order to pave the way behind the diversion and Spraying . Look back two rows of " stick " is the outward point of view , which obviously is to use a diversion . And then along with the exhaust inlet on the grid mix together, stick a short distance behind the grid is dense exhaust position. Obviously, this is to deflector ( the legendary stick ) mixed results with the exhaust gate , in order to vortex flow Cuochu to .

Some people say definitely at this time , J- 10 do not have duck wings , duck wings of the vortex can be used , why should this really necessary? I gave the answer:

At low speed, the duck wing vortex is bound to some , his wing of the main result is to reduce the main wing 's lift on the short take-off adversely affected. J- 10 through compressed air tank rubbed off air in such low speed stage, the exhaust air flow is actually not enough. He is also madly in breathing , so at this time does not exhaust the exhaust gate . So also do not form a vortex , the main wing will not lift a major impact . In the high angle of attack , it is very obvious effect of inlet gas pressure is too strong , the exhaust gate emit large amounts of air . Effect of the pressure head at this time will force the gas tank tremendous pressure gas flow , these two air currents will produce a very strong rubbing with the eddy . In the high angle of attack when the vortex is precisely to solve the wing flow separation , the best way to increase lift .

Su -37 ( can not find a vortex in the SU-37 plans ) of the duck is a close- coupled wing of the main international duck wings , his movements and the main wing , and horizontal tail , and tail pipe coupling action, to achieve the purpose of super mobility . This powerful engine of its former self . Can make up for the loss of lift off stage . The EF-2000, the role of duck wing vortex is rubbing , Although he is far away from the main wing , but his drop-down angle, large angle of attack to just fall on the main wing vortex is most needed position. " gust "is also a short-range coupling . But we all know, China is the worst aircraft engines . China can not use the engine to compensate for aerodynamic configuration of the defects . Air power can only be used to make up for deficiencies .

J- 10, so we came up with the layout - flat front end , frustrating twist swirl tank .

Hirao front means is that it did get used to balance the horizontal tail wing before , so not only can balance the pitch , but also to balance the pressure would have changed the balance of lift . Representing an increase of wing lift , and a part of the power .


Here first is the conventional layout , flat tail in the latter , the focus of the center of lift before the main wing , both sides said the same balance as the pole . The second is a large delta wing tailless layout, he is the front wing to produce lift , the rear wing generate pressure , and the center of gravity to maintain balance . Two Zan program , part of the loss should lift . Which is not good for the heart of the Chinese fighter is rigid . Therefore, China 's Jian-10 using a front canard , as the third figure , the main wing and canard lift lift carried the center of gravity . This is indeed the best solution to avoid weaknesses . Therefore, the duck -wing F- 10 as far as possible from the front by the far wing , so that the eddy canard as far as possible away from the main wing , canard gas tank under the pressure of the air current then will the eddy canard wing separated as much as possible To further increase lift on take-off .





Close look at these two maps, after the duck wing " aerosol "No leaning on the main wing , but rather neatly with the main wing to keep a certain distance.

This design has a problem that generally rely on the inlet under or by both sides , by both sides can not generate the vortex in the main wing , main wing on the lower must be lower . This is why the J- 10 is very, very non- use under the wing of the reasons the mainstream . This layout common during World War II , it is because of this intensity distribution structure - wing carrying body , the beam can be placed Trans . The modern aircraft is alloy , not work on the titanium , wood strength is no longer a problem so little jet fighter with the ( Trainer use of more complex because of simple structure without strong body frame ) . The J- 10 is because under the wing to take advantage of the pressure along the gas inlet on the tank , a last resort.




Now wants to criticize the six F- 10 plus a stick and a high nose under the wing it?
