According to media 3 days report this month, shen Fei " dark sword " high speed unmanned battleplan or already completed earlier test, this is the first kind of supersonic speed battleplan of unmanned concealed body, have the sense of milepost. This model the greatest takeoff weight of unmanned aircraft achieves 10 tons of above, and have outstanding concealed body to fight ability.
By Shen Fei the group develops this " dark sword " unmanned aircraft, the earliest project approving 2003, once was in Zhuhai boat was exhibited 2006 on appear. But, with respect to the level of science and technology at that time character, do not have a person completely to take seriously it. Because at that time no matter our country is the reserve of concealed body technology, still be the reserve of technology of supersonic speed flight, can't support development a world's top-ranking large and unmanned battleplan.
Shen Fei " dark sword " of unmanned aircraft fight index is quite outstanding, what differ with other and unmanned aircraft is, "Dark sword " it is the whole world the first supersonic speed does not have man-machine. On pneumatic design, "Dark sword " the mixture design that used B-2 and F-22 opportunity for combat, airframe submits arrow form, use position of alar body confluence, fuselage section presents the triangle that gives arrowhead appearance on perpendicular direction, compressed clipper-built airframe and wing round glide cross integral lift face, airframe is designed can with but adjustable before the integral position that composition of ala, groovy wing, empennage fits high speed and serious offence to carry motor-driven to fly.
Such layout lets " dark sword " unmanned aircraft had F-22 ability of in that way supersonic speed cruise, ensured again at the same time enough lift, can resemble B-2 in that way, the design is bigger play a storehouse, carry more load. In light of the photograph that publishs according to media place, "Attack by a hidden enemy " should comparative with F-35 battleplan on range, use tall - low - when tall flight section plane fight radius can achieve 800 kilometers, and cabin can be played in airframe interior hang carry bomb of 2 500 kilograms of glide, perhaps hang carrying bomb of 4 250 kilograms of accurate control and guide is PL-12 empty empty missile even.
As technical progress, the aero overload that human place makes, can have achieved 40G greatly most even 50G. But, human body of be enslaved to be enslaved to bears the limit of force, up to now, the overload of each country battleplan connects standing plan to be 9G, also can achieve 11G only greatly most, because,this is, human body can susceptive is the biggest overload is 9G, air man passes rigorous training, OK and brief (1-3 minute) bear the overload of the biggest 11G. So, the battleplan that somebody drives can promote boat report to defy horizontal ability defies increasingly powerful sky is opposite ceaselessly only the menace of sky and ground-to-air missile.
If battleplan instead nobody drive, need not consider driver susceptive limit completely surely so, and need to consider airframe only can susceptive overload limit. So the overload of unmanned battleplan can achieve 20G even 30G! This increased the maneuverability of the plane greatly, design law according to empty empty missile, the ability of 4 times above that the overload of empty empty missile must exceed target battleplan ensures hit the target, that is to say, should ensure the battleplan of 9G of active service overload, empty empty missile should ensure the overload ability of 36G above comes true at least. So, the overload general of modern empty empty missile is ubiquitous level of 40 ～ 50G, if be mixed plus electromagnetism infra-red interference, so although have the overload of 50G, unwarrantable also hit the target certainly.
According to this law, want down overload overload to be able to amount to the unmanned battleplan of 20G, the overload of so empty empty missile must exceed 60G! , and " dark sword " the test of unmanned aircraft ends, the missile of many empty sky that makes each country probably active service makes outdated money between one night. If everything is successful, of Shen Fei " dark sword " let China extremely likely come true " tortuous path overtake " , in respect of unmanned aircraft technology, with one action surmounts the United States, rank world front row.
