The apparent characteristic that weaponry of contemporary and advanced aviation develops is function good, function is strong, small lot, much content of breed, technology production cost is tall, high also, the implementation that its devise an idea relies on the level of research and development of new material new technology, production technology and production equipment ability strongly. To promote battlefield and market competition ability, normally aviation weaponry must be in quality (tall) , efficiency (tall) , life (long) , cost (low) wait for a respect to have integrated advantage. And the perfect union of quality, efficiency, life, cost, need tries to come true through advanced workmanship and equipment technology. Advanced nondestructive detects the technology reachs his to detect equipment is implementation design thought and production concept, strengthen user confidence, raise the important safeguard of competition ability. Develop advanced production project technology, engineering capability of hoist digitlization, automation, it is reasonable solution the significant progress way that modern aviation weaponry is developed quickly and produces definitely and project way. The fast and nimble production technology that is main feature with digitlization, automation especially already made the way of main project technology in advanced aviation weaponry is developed and be being produced. And nondestructive of digitlization, automation detects the technology is the main component that digitlization, automation is made and advanced aviation makes equipment. Wait for the ceaseless application of new material as composite material, nondestructive of digitlization, automation detects the crucial technology that technical development and success application already made aircraft design and digitlization, automation make a process, it is especially in new material and new technology research, new structure and the process that new machine develops, nondestructive of digitlization, automation detects the technology is producing mainer and mainer effect. Nondestructive of the application of composite material aboard and digitlization, automation detects in recent years the level of outfit machine application of composite material already became contemporary aviation to equip the mark of advanced sex, joseph F Rakow is forecasted, in future in 10 years, next generation planes are the plane of composite material, composite material is not from in the past bear force structure is being used at ceaselessly advocate bear force structure. 10 years ago, dosage of Boeing777 composite material is structural heft 10% the left and right sides, and dosage of Boeing787 composite material achieves structural heft 50% the left and right sides. Besides Boeing787, dosage of Airbus380 composite material also achieves structural heft 25% the left and right sides, compare with photograph of airframe of Boeing787 composite material, airbus380 be lifted breathtakingly even if designed complete composite material box of the ala central. Composite material rudes in the applied posture a bit on military plan at civilian machine, for example dosage of F/A-18C/D composite material prep above 20% , and report according to Joseph F Rakow, dosage of F-22 composite material jumps to 60% the left and right sides. Structure of composite material application also by be not in the past bear the simple structure of force develops bear force structure, whole structure, large construction and complex structure. Accordingly, composite material structure has decisive effect in modern plane. (1) composite material workmanship optimizes the control with cost to cannot leave nondestructive of digitlization, automation to detect technology. At present the material of composite material structure and production cost house do not fall high, structural size is larger and larger, structural member form is more and more complex, need uses nondestructive of composite material of advanced and reliable digitlization, automation to detect technology, be optimized in time for composite material craft and structural member is made provide feedback information, the help stabilizes craft, raise the percent of pass of the product. Because composite material nondestructive detects,perforative Yu Fu adds up to material composition to shape, assemble, experiment, safeguard / maintenance, use whole process, accordingly, composite material nondestructive detects the totle drilling cost that cost and efficiency affect composite material directly, and reduce detect approach of a of cost effective technique is to develop nondestructive of digitlization, automation to detect technology, rise detect efficiency. (2) the batch production of composite material structure and detect need uses nondestructive of digitlization, automation to detect technology. Composite material structure needs to undertake 100 % are enclothed normally detect. Hold machine application and plane batch production in great quantities as composite material, the quantity that nondestructive of composite material structure detects increases quickly, whole process of the detected time-consuming, efficiency and plan development that affects a plane directly and production. With check of nondestructive of intake duct of F -22 composite material test produce the expected result is exemple, use supersonic detect technology, need 24h / about. Size of composite material structure is larger, detect time-consuming more; Structural form is more complex, detect efficiency can be reduced apparently, detect time-consuming also meet more. Accordingly, so big detect workload, the handiwork that relies on a tradition only detects, satisfy a requirement hard apparently. (3) composite material bear the design application of force structure needs to use nondestructive of digitlization, automation to detect technology. At present composite material application already by is not in the past bear the simple structure of force develops second bear force structure even bear force structure, whole structure, large construction and complex structure. Accordingly, detect to nondestructive of composite material structure technical demand is higher: Need to undertake nondestructive detects not only, need those who get quality of composite material interior and blemish to quantify information more; Ask check gives blemish not only, still need to establish the organic connection of composite material blemish and structural function, build corresponding blemish to evaluate standard; Need not only can check goes out statified, loose wait for structure of a few influences the macroscopical blemish of mechanical function, still need check to give a likelihood to affect structural exhaustion performance microcosmic or distributing model blemish. This uses nondestructive of digitlization, automation to detect with respect to need the technology will satisfy these requirements. (4) design of flying pilot life and need of dependability of composite material structure use nondestructive of digitlization, automation to detect technology. Characteristic of a of modern plane main technique is life of requirement long life, and the design application that waits for significant position in airframe, wing as composite material, composite material structure must satisfy expectant design longevity. Because there is process of intermediate material treatment on whole of composite material structure, once solidify process is finished, mean force of whole of composite material structure to learn function to secure, unless be in,obvious quality question appeared in production process, if interior produced limitation. Follow belt of composite material structure to arrive when plane structure is medium when the blemish that existence does not allow on those designs, will affect overall safety to enlist in army with service life. Accordingly, must detect through advanced and reliable nondestructive the technology ensures the dependability of composite material structure and quality. Apparent, the handiwork that relies on a tradition only detects cannot satisfy a requirement, an efficient technical way uses nondestructive of digitlization, automation to detect namely technology. Nondestructive of composite material digitlization, automation detects nondestructive of digitlization of current situation composite material, automation detects the technology enlarges outfit machine to apply dimensions and modern plane design to make a characteristic put forward ceaselessly as composite material in recent years. Detect in the light of what differ appearance of phase of environment, working procedure, structure, at present nondestructive of composite material digitlization, automation detects on the technology cent is two general orientation: It is to be based on the composite material digitlization of the instrument to detect technology; 2 it is to be based on nondestructive of the composite material digitlization of equipment, automation to detect technology. The composite material digitlization that is based on an instrument detects the nondestructive that the technology basically uses at solving a few application circumstances that realize automation to detect hard and composite material structure detects, if composite material repairs a process,medium nondestructive detects, composite material is complex of structure and complex structure place detect. Basically be the digitlization that carries pair of testing instrument, will rise to detecting the digitlization processing capability of signal and blemish quantify analytic ability, realize a few such as to detect parameter, model detects the record memory of signal. Basically be with supersonic testing instrument the technology is given priority to at present, use supersonic bounce technique to detect more. Those who be worth to point out is, the digitlization on the market is at present supersonic testing instrument and blemish evaluate a method is to be aimed at metallic stuff to design development mostly. As a result of the oneself characteristic of composite material structure and blemish feature, the digitlization with need normally special development detects technology, implementation detects signal high fidelity digitlizes processing, rise detect resolution, decrease detect blind area, have drawback quantify evaluate. With respect to colophony base composite material, basically be to use supersonic digitlization nondestructive to detect at present technology, it includes supersonic transducer technology, supersonic technology, signal to handle technology, blemish to assess technology and instrument technology. From 20 centuries at the beginning of 80 time, institute of Beijing aviation production project began composite material to digitlize nondestructive to detect technical research, studied high resolution exceeds RF of sonic transducer, composite material successfully supersonic detect method, blemish identifying and evaluate method, composite material high resolution is supersonic detect series instrument, it is the pillar technology that nondestructive of domestic composite material detects and main measure all the time, the scientific research that waits for a branch in aviation, spaceflight, enginery, traffic, air force and manufacturing front line produced crucial effect, study built high resolution exceeds sonic transducer technology and blemish to assess a technology especially, have apparent technical characteristic in the world up to now. Nextpage is based on these composite material to digitlize supersonic testing instrument and blemish to assess a technology, can reach its place to the blemish in composite material (deepness) , area, property, type undertake quantifying assessment. Those who use Beijing aviation to make project institute produce is muti_function composite material high resolution is supersonic testing instrument (MUT -1) lead supersonic digitlization to assess a technology with the composite material hole that already built, can undertake exceeding lung-power to change assessment to content of hole of typical composite material, can see from inside the result hole is different in composite material distributinging circumstance of the position. Hold machine application and batch production as composite material batch, the composite material digitlization that is based on equipment, automation detects the technology develops in recent years rapid, in be made NASA, Boeing, LockheedMartin, Airbus in composite material structure at present and producing a course, developing nondestructive of digitlization, automation to detect energetically technology. Basically be based on supersonic method at present, detecting on foundation of signal digitlization processing, be aimed at component of different composite material, use scanning orgnaization to design technology and numerical control technology, carry special technical design and equipment research and development, nondestructive of the supersonic digitlization that solves composite material component part, automation detects. The composite material that is based on equipment at present is supersonic digitlization, automation detects the technology basically includes supersonic transducer technology, supersonic technology, scanning technology, control technology and blemish to assess a technology, can divide for supersonic through transmission technique and supersonic bounce technique two kinds big. (1) nondestructive of the composite material digitlization that is based on supersonic through transmission technique, automation detects technology. Use incident sound wave to undertake in the attenuation change of the energy when crossing composite material blemish identifying and detect, the west favors this kind detects quite method, supersonic transducer installs the orgnaization of much axis scanning in 2 semmetry to go up respectively, below action of numerical control system, pass athletic process designing to control, make 2 probe right be detected composite material component undertakes scanning automatically detecting. When using through transmission technique to detect, detect to exceeding sonic transducer to be mixed with the resolution of the instrument blind area requirement is relatively inferior, but need has very good synchronism and scanning control technology. Compare with supersonic bounce technique, its are main technical characteristic still has: · exceeds sonic transducer to need to approach work from two side; Synchro control of · supersonic transducer and model the face dogs complex; · to complex part, can use only channel job only normally; · detects efficiency is not tall; · technology cost is high. (2) nondestructive of the composite material digitlization that is based on supersonic bounce technique, automation detects technology. The reflection information that uses incident sound wave to transmit generation in composite material undertakes blemish identifying and evaluate, europe favors this kind detects quite method, supersonic transducer installation is on orgnaization of scanning of more than 1 axes, pass athletic process designing, transducer falls in action of numerical control system, to be being detected composite material component undertakes scanning automatically detecting. Normally ply of individual lay up makes an appointment with composite material 0.

13m M, the to supersonic transducer and instrument resolution when using bounce technique to detect accordingly and detect blind area demand is higher, but do not need to have synchronous scanning orgnaization, detect sensitivity is taller than through transmission technique. Compare with supersonic through transmission technique, its are main technical characteristic still has: · exceeds sonic transducer to need to approach work be detectinged from a side only; · supersonic transducer face dogs the demand is high; · can realize much passageway to detect; · detects efficiency is tall; · technology cost is inferior. Use which kinds of digitlization, automation no matter supersonic detect method, need to have very good model the face dogs technology, signal processing technology and supersonic system are comprehensive technology. Be aimed at structure of large composite material especially, the scanning method that uses on international at present basically has 3 kinds: Show religion, the CAD model that is based on a spare parts and measure profile modeling. But detect actually applied case is not good: Show teach and the methodological efficiency of profile modeling is too low, the CAD model of spare parts be detectinged arrived composite material detects working procedure, already unwell with. So, searching new fast and applicable scanning method is the urgent matter that settles digitlization of composite material component, automation to detect. In recent years Beijing aviation makes project institute study in the new technology that develops this field all the time, studying one kind is based on freedom of spare parts of composite material be detectinged face dog scanning technology, in order to solve above of 7500mm × 6000mm the supersonic digitlization of component of large composite material, automation is efficient nondestructive detects, already completed technical program test at present, enter a system to design production phase. Institute of Beijing aviation production project is the professional institute that home is engaged in composite material nondestructive the earliest detecting, be in early 20 centuries 70 year end at the beginning of 80 time, began composite material nondestructive to detect technical research, be aimed at composite material characteristic, put forward early or late and studied high resolution successfully RF is supersonic detect transducer of method of technology, blemish identifying, testing instrument, small blind area, blemish is become become like method, automatic scanning resemble detecting equipment, formed distinctive composite material to detect technical system, apply a domain to produce main effect in domestic composite material all the time. If developed FJ series high resolution to exceed series of sonic transducer, composite material without blind area complex place of component of composite material of supersonic testing instrument, CUS-21 is supersonic testing system, CUS-22 is supersonic suit oneself detect equipment, MUI-21 is large composite material structure is supersonic detect automatically composite material of technical equipment, CUS-2F is twined supersonic and automatic detect technical equipment, for domestic composite material research and industrial application branch were offerred strong technology supports and prop up, be developed in aviation model and main effect is being produced all the time in production. The digitlization of UltraScan 9000 composite material that developing especially, automation is supersonic and automatic scanning testing system, amount to 20 detect passageway, use distinctive dog automatically scanning technology, the automatic scanning of the composite material component that can get used to norms of above of 7500mm × 6000mm detects. Use this kind of digitlization, automation supersonic detect technology, can be detected through visual image means reproduction the in-house quality circumstance of the detailed fractionize cloth of blemish of interior of composite material structure and whole structure, have drawback quantify evaluate. To composite material nondestructive of digitlization, automation detects the reflection of development nondestructive of composite material digitlization, automation detects is reach its with composite material the professional technology closely related workmanship, design of the composite material that its develop to must join self cheek by jowl with application, structure and make, the characteristic such as application has sound program, the composite material research and development that Boeing and Airbus company link oneself all the time plans and produce the job for example, in begin nondestructive of composite material digitlization, automation to detect technical research and application. Nondestructive of the composite material digitlization that is based on equipment especially, automation detects, specific aim is stronger, the person that has gone to Boeing and Airbus company looking around can feel in composite material nondestructive of digitlization, automation detects respect, they have apparent different characteristic and technical train of thought. Nondestructive of composite material digitlization, automation detects technical key is the special and professional facility that needs to very powerful technology supports, collect nondestructive detects, control of processing of sensor, instrument, signal, scanning, into picture and the much major such as the computer, mechanical, electric equipment, numerical control, much discipline at an organic whole, extremely professional strong, belong to a special exemple technology to design application, must combine composite material, craft and structural design to make etc undertake special design. Boeing and Airbus company are cost gigantic endowment, undertook long abidance research and development and technology are accumulated, just have today's technical dimensions. Our country is in this respect a few years introduce case simply to make clear repeatedly, should from go up at all solve nondestructive of composite material digitlization, automation to detect, introduce 9 mechanically to detect only equipment, far cannot from go up at all solve nondestructive of digitlization of composite material structure, automation to detect. On one hand, at present our country should cost a large number of capital every year to be bought from abroad a few suit what oneself model is developed and produce a characteristic to detect not quite equipment, and these detecting of equipment introduce lack mostly again the technology is relied on and technology of form a complete set supports, lack application development and relevant technology form a complete set, because this forms effective productivity hard. On the other hand, be developed in model and nondestructive is badly in need of detecting again in production technical equipment will ensure the mass that holds machine structural member, the help stabilizes craft, for material research provides evaluation measure, use feedback information for the design, assure quality of parts of development of composite material structure and traditional Chinese clothes of model production process. Accordingly, the development program henceforth and train of thought, should ego of base oneself upon, make full use of international technology platform, according to oneself model batch production and composite material install machine application characteristic, use active fund, nondestructive of digitlization of structure of development composite material, automation detects the technology equips, build nondestructive of the digitlization of composite material structure that suits oneself technology characteristic, automation to detect technical system and platform, enhance the technical connotation that can develop continuously.
