Card-60 and rice-26 data, push forward it national product to turn.On getting gold battery dragon's news, those senior experts sharply feel gold battery dragon's invention to developing of our country for use by the military helicopter as if the absolute being help, but the desire will in fact use to turn difficulty and workloads all biggest.Motor once replacing Wo stalk with the electric motor-decelerate machine to drive lord Xuan wing, those are complicated of provide fuel with slippery oil of tube road all need not, the huge Zao voice won't reply existence as well, the advantage is obvious.The low speed of direct current electrical engineering greatly twists Ju in this situation very suitable for use, and end of the tail of anti- the wing twisting small Xuan can be driven with the alone electrical engineering, can save go to complicated of deliver device.In view of the fact gold battery dragon's power supply is very in brief used for the electric voltage that adjusts soon to control, the leading of direct current electrical engineering carries function again outstanding, so the design set decides to use direct current electrical engineering.But the electric motor be always called with bulky Zhao of, particularly is a direct current electrical engineering.Therefore the crux develops the low speed that the big power weight compares to greatly twist Ju direct current electrical engineering.Actually the gasoline machine is originally also very heavy, just after several years of unremittingly make great effort to just develop a high horsepower weight compare of aviation motor, afterwards again drive power weight than largerly blow out gas machine to replace.
The national section Wei immediately organized aviation direct current the electrical engineering offend to close an item set, after effort of very hardships, last for 9 months finally took out in the world first the set aviation direct current electrical engineering.The electrical engineer adopts sparse soil material and aluminum metal alloy material of big Ci flux and completed to lose weight to design, the power weight ratio attains 3.1 kilowatts/kilogram.This helicopter appropriation direct current electrical engineering useds for refitting a domestic WZ-10 armed helicopter.The electric motor of this set 1400 kilowatts at the right moment sticks to match in the top of helicopter like a huge park a round flat cake, diameter and fuselage together breadth, above 1,dr dre beats.2 meters, therefore turning power Ju is big, it directly drives a huge Xuan wing.
Offends a pass with electric motor of at the same time, the helicopter item set divides two person's horses.The electricity system of a set of more than 1,000 existing helicopters that are responsible for reforming our army the etc. is mainly to tore down generator, storage battery and go together with electricity device and pack a gold battery dragon and lately go together with electricity device, each helicopter can lose weight a lot and also raised the credibility of electricity system.Refitted a novel semi-conductor air condition machine, added a high performance of hot become an elephant instrument.The function of helicopter also had an exaltation.Their progresses are quicker.
Another task wants to be heavily many, they are responsible for reformation to control system.To the control of the Wo stalk-Xuan wing and isn't very same to the control of electric motor-Xuan wing, in addition to theoretically carrying on a research, they are with the helicopter carry on experimenting more to obtain control parameter.Had no gold in the beginning battery dragon to use electric cable power supply.The high performance electric motor has no and then pack the electric motor that the process first step lose weight first up the helicopter, for example the first set pack the direct current electrical engineering of 1400 kilowatts of WZ-10 heavy reach to more than 2000 kilograms, is doing not take weapon and fuel as well so much, to take-off always weigh 5500 kilograms of WZ-10s also have no influence too greatly.Let it trails electric cable to test various flight status under of data.
Finally can carry on trying of the first dynamoelectric helicopter to fly in the world today.This is an important event, always the material department vice minister cow star lieutenant general in the sky, Hao ambition the major generals just all arrived at to try to fly a field.This display all in shape has very great difference in Ms WZ-10s and former WZ-10 of military authority big member in front, the motor of fuselage back-decelerate machine to be missing, be just a disk-like in shape super thin the big direct current electrical engineering of diameter tightly stick in the coping, it owns 1400 kilowatt powers and used for directly driving lord Xuan wing.The spirit of helicopter moves characteristic better.More astonishing is letter way the tail oar be missing, only a slightly a little bit thick tail beam stretches backward square, it carries a department to have one to hang tail.This is the list Xuan the helicopter of the wing.
The Hao ambition just asked a flank of total designer Huo farmland agriculture:"We also use last the American's wreath quantity control was technique's building helicopter without the tail oar?"
The Huo always says with a smile:"I come to introduce this freshman's baby for everyone.Wu Zhi-10 is usher in from France at the end of 20th century the virtuous cooperation of method develops of the "tiger" type bear arms the technique of helicopter and develop a development by oneself of light armed helicopter.Can say weapon and basic frame protects to stay, besides which, , we come to a reformation for keeping form but change substance to it.Say small aspect first, the power electricity system of the whole machine thoroughly changed, the power quality and credibility raised, and the weight still eased a lot.New semi-conductor air condition machine since is light, Zao voice again small, and definitely don't make the cold danger for leaking, the airplane pilot will have already sliced body meeting.The semi-conductor is compulsorily cold hot to become the function of the elephant instrument"probe" is that the world is top-grade.Although these improvements are unattractive, very practical.
"The big improvement contains 3, there was two everyones one eyed to see, Clause 3 was what eyes can not tell, I introduce first.This Xuan wing is well-known of'invisible Xuan wing', the science and technology personnel's innovation is an our country, it significantly improve existence ability in the battlefield of helicopter.The huge Xuan wing is a helicopter up most attractive of parts, American of' reach Ci'the fire control system to adopt pulse many Pu Lei frequency Jies change radar, make use of many effects of Pu Lei to test to find out a turning of Xuan wing soon, and pass calculator processing to get rid of the time of leave target wave, can get the distance and 3D data of low altitude helicopter.The United States and Russias all made invisible Xuan wing, our have a little unique, the Xuan wing makes framework by high strength hard aluminum tube and divided threes to reply three kinds of coatings that severely absorb different wave-length radar wave on the hard aluminum tube, because want to study a kind of coating that can absorb various wave-length is too difficulty, the wing noodles is deeply the special kind carbon fiber resin to shoot big parts of radar wave.On radar wave the Xuan wing that project light upon high speed to revolve, one small part drive wing noodles absorb, deeply shoot hard aluminum to take care of Tu Ceng of again drive different degree ground strong dint absorption, again glint come out of radar wave, not only the signal is very weak, and is some not continuous time wave drive calculator regard as'miscellaneous wave'processing drop.This has to be much better in the plane wing surface than, the protections that are subjected to wing noodles.Through resist a test, confirm pulse, many Pu Lei frequency Jies changing radar can not probe into the new helicopter of low altitude."
"Audience"s on the field all became fascinated, "invisible" to helicopter is importance too, the American ballyhooes and turns so much money.We also made out now and how to not became fascinated.
" The Hao major general just says of'circulation control technique', is a technique that the American is practical to turn at the beginning of 90's in last century, they cleaned tail oar and opened on the tail beam long sew, pass side to blow breath to make lord the tail of the Xuan wing flow the speed in two sides of tail beam different, produced from here balance anti- twist the side dint of Ju.Have no eruptive current of air to fly to an end of the tail inside the tail beam, from can control of blow out gas awl direct jet to manipulate by providing a direction to push dint.We used this concept, but had innovation:The outer shell of this tail beam from one set the small electric motor turn, because of attaching the tail of the wing of the noodles effect lord Xuan to flow formed speed in two sides of tail beam bad, equally produced the side dint of equilibrium anti- torque.As long as the control turns soon can provide direction to manipulate dint.The our method economy energy, Zao voice is much lower.
"Need to point out a point, after wheat way company released ＭＤ 520 Ｎs had no tail oar helicopter, this a technique didn't get more applications.The reason was a later helicopter to mostly use Wo stalk to blow out gas a motor, although the strong current of air that they jet backward provided part of headways to push dint, biggest interference the main Xuan wing blow toward the tail beam of next wash current of air, cause circulation control the dint can not form.We WZ-10 dynamoelectric Xuan wing of next wash current of air to be free from interference ground to vigorously blow on the tail beam, the tail beam outer shell revolves after output circulation side to push dint very sturdy.
"The improvement of most is certainly the super thin and big diameter that takes a set power as 1400 kilowatts to raise the tallest speed to 380 kilometers/ per hour.The electric motor is whole closingses of and be basically not afraid of sandstorm and bird when the low altitude flies.
"The improvement of flexibility is also the unexpected happening that comes from an expert.The power device of original helicopter is mostly free turbine type motor, its power turbine and gas take place of machine have no machine connect
