Be in land air defence and the need with safe coastal areas and territorial seas, go up century 90 time, china began the research that the technology cheers in sky, the most inchoate achievement of research is two type, the banging oil of Xi’an aircraft company – 6 and the annihilate of Shenyang aircraft company – 8D battleplan, of these two planes cooperate, make annihilate – 8D battleplan fights radius can exceed 1000 kilometers, maintain the presence of pair of south maritime space, 6 planes can cheer a banging oil 16 tons or so, can satisfy pair of annihilate 8D battleplan cheer for many times.
Going up century air force of 90 time China got from design department of Russia Su Huoyi revive 30MKK fighter-bomber, this plane has doughty attack ability and over-distance range, beardless auxiliary tank, but this plane still is had ability is cheered in sky, aircraft nose is left have oil pipe gets in receiving the air that puts type, cheer moment to open, call in at ordinary times, make the same score completely together with airframe surface, do not bring any additional resistance, this is a kind of very distinct advantage, and the annihilate that China develops in contemporaneity – 10A battleplan, used annihilate 8D battleplan similar design, suffer vitta to use stationary design, but from the point of detail, annihilate – 10A battleplan cheers a canal to design in sky, more illusive like France 2000 battleplan, plane straight lever sufferred vitta to use wing section design, obstruction noise is less, do not have any bad influences to plane maneuverability and the oldest rate, and annihilate – 8D battleplan, because the undeserved design of vitta gets in sky, supersonic speed flies, suffer vitta shock wave to be able to interfere intake duct to cause engine to jockey into gas, caused 1.4-1.6 operate between Ma He limitation, lost the high speed dominant position of core.
Annihilate 8D battleplan is Chinese battleplan first time the technology is cheered in attempt sky, succeed not completely
In annihilate – on 10A battleplan design, stylist also has thought contractive type gets oil pipe, but limitative element is very much also, the primest limitation factor is, annihilate – 10 as a kind of light plane, nose size is smaller, the space is more cramped, be hard to accommodate one a complete set of to get oily plant adscititious telescoping mechanism, similar case also happens on Russian-made battleplan, russia is large battleplan, revive – 30, revive – 35 and MiG – 31 used nose oil pipe gets in adjustable sky, and smaller MiG – the design that 29 battleplan used distinctive adjustable and adscititious large commutate to overspread union, basically use in Malaysia MiG – on 29 battleplan.
Annihilate – 10A battleplan is used fixed get vitta design, the advantage is a structure simple, do not take up valuable nose space, but the weakness is not little also, increase high speed noise for instance, and also can reflex to radar sectional bring adverse effect, this kind of design does not become an issue in times of 3 acting machine, but arrived times of concealed body battleplan, this kind of design cannot be accepted completely, so Cheng Fei develops annihilate – 20 battleplan moment, although the plane has the oil inside 10 tons of level, fight not to need normally cheer in sky, with respect to the cruise time that can assure plane 3-4 hour, but stylist still was added to the plane the function is cheered in sky, do not cross this, must use telescopic design.
Annihilate 20 battleplan nose is left, vitta design gets in using covert air, mask by two buccal lids
Design this, the biggest gain is, annihilate – 20 battleplan have to mix eventually revive – the head of large scale computer that 30 battleplan battleplan rivals, nose large space is much, it is easier also that oil pipe gets in arrangement sky so, this also is first time of battleplan of Chinese own research and development is used telescopic design, the purpose depends on providing overall concealed body performance for the plane, and also can develop adjustable the shtick that gets oil pipe, cheer in normal sky, battleplan flight rate is not high, be in mostly 400-500 kilometer is horary, although use simpler round tube sectional get oil pipe, flight noise increases more finite also, communicate to pilot radio, and audition does not have any bad influences.
Strict for the angle from concealed body, annihilate – 20 vitta design gets in using this kind of adjustable air, faulty also, although pass old test, besides cheer speed one times slower than hard canal besides, main malpractice is, cheer in gentle style sky, need is cheered of machine cheer towed bird, cooperate those who get oily chance to get vitta job, in process of whole butt joint, the awl that cheers towed bird covers tube stiffness very poor, get easily the interference of air current, horizontal all along returns lash case more serious, awl covers easy lash to arrive annihilate – 20 nose, cause concealed body coating to wear away, bring about concealed body function to drop, so battleplan of air force F-22 used hard canal to cheer, the plane cheers pedestal in the installation on back.
Annihilate – 20 battleplan future may raise strong pattern oily interface suffers in sky
Annihilate – 20 battleplan use back hard canal to cheer, change one’s costume or dress the technology is not sophisticated, mere need increases a wear-resisting to cheer pedestal impulse withstandly, adscititious cover board of one caboodle fold, interior and plane gasoline tank join, similar design has on plane of American much money reflect, for instance American F-15, f-16 battleplan, especially Chinese stylist has contacted F-16 battleplan a lot of times, it is not difficult that to its mapping is modelled on, total value also does not calculate complex, chinese annihilate – 20 when can use more be at ease, and quicken the hard canal with rapidder rate to cheer?
Main difficult point depends on cheering machine, chinese air force has banging oil the 6 Yi Er with few number are cheered in 78 sky machine, these two are cheered machine use gentle style to cheer a design, the plane did not find a place for hard canal cheers a system, gentle style cheers a design to be opposite carry machine revise few, mere need installation cheers towed bird can, and hard canal cheers the control system with a very complex need, and need personnel operation, cheer speed tall, attitude is stabilized easily is the largest dominant position, but taller to carrying confidential to beg, chinese air force also lacks appropriate platform.
The biggest hope of future is plane of CR929 wide system, this wide body long-range aircraft changes his costume or dress cheer in voidance machine, can offer 100 tons cheer ability, it is Chinese air force optimal choice. (the author signs: Flood)
