On January 29, russia battleplan of the Five Dynasties, namely PAK FA(" system of weapon of aviation of future of front air arm " ) in Er of A Mu of area of Russia far east - in all manufactory of Qing Chengfei machine head fly. According to the report, head fly lasted about 40 minutes, head flying test pilot is Gai Bogedan thanking Er.
Develop setting
20 centuries 90 time later period, the United States begins to develop new generation battleplan. The F-22 that fourth company of horse of · of Losk Heed of final make choice of develops air force is F-15 of opportunity for combat of U.S. Army brunt replace model. Face the American challenge on martial technology, regard aviation of on the world another military affairs as big count dearfoam slippers for women ry, russia is natural cannot outside place oneself thing, russia offerred the development plan of PAK FA in 90 time end. April 2001, russian army raised the best selling resealable bags the tactical technology requirement of PAK FA, design department asks around the technology of FAK FA related immediately, with " technical proposal book " the form launchs contest bid. On April 26, 2004, the project committee of Russian government announces the plan of Su Huoyi design department to win the bid. Since Suhuoyi after design department wins the bid, the aviation industry group of world each country, army and all without exception of broad aviation lover pay close attention to the tendercy of PAK FA, russia media respect understood the existence of FAK FA project the earliest 2000, stem from later confidential, this name disappears from communal media inside period of time. Su Huoyi design department call the best selling hans wilhelm s I-21 the earliest in FAK FA of report lieutenant general, meaning for 21 centuries battleplan, use interior to design code name T-50 formally again later.
In the hearsay of all sorts of occurrence version, PAK FA is guessed place is surrounded all the time. The function of this kind of battleplan how? What kind of is system of its pneumatic appearance, engine, electron, weapon system? The technology of Russian air force asked to draw the outline of the fundamental condition of PAK FA.
The technology that gives out according to Russian army asks, the main characteristic of PAK FA includes most popular selling dearfoam slipper : Have versatility, can fall in all sorts of complex weather conditions can destroy accurately empty medium or ground target, but in order to contend for mastery of the sky preferential; Plane takeoff weight is in 20 tons of less than; Fight radius achieves 1100~1300 kilometre; Speed of the biggest flight is Mach number 2, have exceed capacity of cruise of velocity of sound; Have tall maneuverability and tall nimble sex; Have capacity of body of radar, infra-red, optical concealed; Have short be apart fr resealable bags for food om case fall function, the distance falls to be in since 300~400 rice.
Jump again and again the acceptance of the ticket
After the development work of PAK FA begins, the outside wants to understand the true appearance of this machine an dearfoam slippers d performance data agog, and Russia respect is aing string of 1 from beginning to end the appetite of the outside. Inchoate the plan process that publish and the real progress later not agree with badly. Original plan realizes archetypal prow to fly before 2007, but plan of whole later plan is adjusted substantially. Russia of the beginning of the year gave off a message again 2006: PAK FA can be in 2008 head fly. The Fulajimier Mihayiluo of commander of Russian air force at that time the husband alleges will not hesitate all cost realize archetypal prow to fly.
2006, the wind tunnel test that PAK FA airframe devises has been finished, the development work of boat cable system and sensor also nears end. Arrived 2007, su Huoyi design department gives a few informations about PAK FA to outside divulge eventually: The production job of first archetypal machine has begun. 2007 the beginning of the year, the imaginary figure of a piece of FAK FA appears in Russia famous engine produces business -- on the official website of Saturn production combine. In in those days the Parisian boat July is exhibited on, russia holds the post of when the Ivanov of the first Vice Prime Minister announces FAK FA will 2008 head of the end of the year flies. Had done not have however how long, transmit a message from Russia again, head flying time remit to 2009 the end of the year.
modern dining chairs2009, · of Alexander of commander of Russian air force lustre forest state PAK FA agrees to will surely be in head of the end of the year flies. Those who make a person regretful is, PAK FA head fly to be deferred once more. When the people of proper attention FAK FA is gradually disappointed, PAK FA is being become eventually of the end of the year will undertake slipping first running experimenting on December 24. Slip this run experiment, the people that gives attention PAK FA again lights an a gleam of hope. Right now the outside has guessed probably: Leave a time that fly already not far.
Cut a figure head fly
Slipping run after the experiment, design department announces Su Huoyi, of PAK FA first test-fly is in surely on January 29, 2010. This, su Huoyi design department did not fail to keep an appointment again, people saw PAK FA eventually " the truth of sth. " .
Look from picture and video, PAK FA uses the groovy position of alar body confluence, airframe and wing make the same score glide to cross, other features include rectangle inclined cut the buy inside abdomen of gas mouth, machine double play storehouse, extroversion to be moved completely double hang down end, repair and maintain is big edge.
Layout of alar body confluence can reduce the pneumatic interference of wing and airframe, reduce exceed obstruction of velocity of sound, form bigger lift area in order to add plane lift. The rectangle of PAK FA is inclined the opening taking energy of life that cuts gas mouth and F-22 is similar, this kind of means is become it seems that worldwide the standard form that the 4th acting battleplan takes gas mouth. Of the buy inside machine abdomen double playing a storehouse is a Russian first bomber form play a storehouse to decorate means to transplant to go up to battleplan. Alar face is lesser move completely double hang down end can exceed velocity of sound in the plane reduce when cruise hang down the obstruction that end produces to the plane.
Be worth to be carried is, PAK FA used movable side technology. The plane falls in the large position that receive part, edge the eddy taking off body of around generation can be on wing the face is particular limits produces attraction, raise the coefficient of the biggest lift of the plane, and because of the edge can reduce wing to be mixed relative to ply reduce wing to exhibit bowstring effectively to be reduced than exceed obstruction of velocity of sound. Say continuously a few whiter, movable edge action is similar to the duck ala in position of 3 alas side, but PAK FA the confluence with its and alar clever body, reduced radar to reflex an area greatly below the premise that has as same as duck ala efficiency, improved concealed body performance, can yet be regarded as the tweak of confluence of body of ala of a kind of give attention to two or morethings.
Put the doubtful point that be in
Because at present the outside does not master the detailed data of PAK FA, a lot of function also cannot master the plane completely. The certain part on machine or equipment still cannot understand its job status and use. For example: The large commutate cover of wing root ministry cannot judge its interior at present is why device. Speculation considers as an electron antagonism system, speculation considers as inside the weapon that bury type plays a storehouse, also speculation considers as installation protect form antenna.
In addition, the intake duct design of the plane also is denounced more. Will look according to the photograph that publish, engine intake duct did not do the design of S form intake duct of similar F-22, the illuminate beam that this means radar can be hit to the lamina taking energy of life of engine directly, ver resealable bags best buy y adverse to the concealed body of the p the most popular hans wilhelm lane. One of main demands that PAK FA designs are concealed body, why does that appear even do this kind destroy the design of concealed body?
What red peripheral has is inspect to appear before nose surprising also, equipment in new generation battleplan airborne active photograph accuses a radar (below the circumstance of AESA) , infra-red before does the action that inspects facility still have how old? Say the Russian is right oneself AESA radar self-distrust? The problem of such still has a lot of, do not spread out one by one here narrated, believe these doubt are met in the future as PAK FA be decoded gradually and get reasonable result.
furniture lightProspective development
The success head of PAK FA flies it is an important milestone. If everything is successful, PAK FA project will walk up from now on " test-fly - finalize the design - equipment " the road of army. Can infer this will be a road that was full of hardships and dangers and challenge. Type of nowadays Russia brunt revive - 27 1977 head 6~7 was experienced again after flying success year test-fly unit of equipment of ability big batch, from T-10 prototype machine development is become during this present revive - 27, experienced very big change. PAK FA also can take the way with same T-10, improve in the experiment namely, development, perfect. After all the plane that we see PAK FA is a the most fundamental condition now, new-style boat cable system, new-style engine, new-style weapon is test to it. There will be perfect PAK FA to appear before common people after believing to be in a few years. (Towering)
