【正文】 hnological development within the Chinese aerospace industry. Several Chinese aviation authors have hypothesized that the J10B serves as a “technological stepping stone” with respect to the development of the more advanced J20. For example, Feng Cao argues the J10B and the J16 AESAs were likely used to test technology related to the J20’s AESA which would be a second generation Chinese design. By virtue of the larger nose volumes in the J16 and J20 airframes, it is highly probable the two aircraft will feature radars with more T/R modules than the J10B’s radar. 通過(guò)參考中國(guó)航空工業(yè)的漸增性開(kāi)發(fā)模式不難推測(cè)，在單獨(dú)一代雷達(dá)中，中國(guó)的封裝技術(shù)水平很難趕超美國(guó)同行。許多中國(guó)航空作家都預(yù)測(cè)，與更加先進(jìn)的J20相比，J10B只扮演了“技術(shù)墊腳石”的角色。比如：朝峰（音譯）認(rèn)為，J10B和J16的AESA系統(tǒng)為裝備J20的AESA系統(tǒng)提供技術(shù)測(cè)試，而后者則是中國(guó)第二代有源相控雷達(dá)系統(tǒng)。憑借更寬敞的機(jī)頭鼻錐部分容量，J16和J20所裝備的AESA雷達(dá)可能擁有比J10B更多數(shù)量的T/R組件。The J16 utilizes the Su27BS airframe which has room for a meter aperture in the nose which is on par with the F15 and F22 in terms of volume (Kopp, 2012). The 1,500 element N036 Tikhomirov NIIP AESA has a similar aperture size to the electronically scanned array (ESA) IrbisE radar featured in the Su35 series of fighters which shares the base Su27 airframe. If the 1,760 T/R figure is correct it would indicate the Chinese aerospace industry has eclipsed Russian T/R module packaging technology as the N036 is arguably the most advanced Russian fighter mounted AESA. Similarly, the most advanced US fighter mounted AESAs such as the APG77(V)2 and APG82(V)1 contain 1,500 T/R modules*. While the prospect of Chinese avionics firms reaching parity with US and Russian firms is more plausible within two generations of designs, the author is skeptical the 1,760 figure is correct given the unsubstantiated nature of the image and the fairly substantial 260 T/R discrepancy between the J16 radar figure pared to the most advanced US and Russian AESA designs. Therefore, the author speculates it would be more reasonable to assume a figure between 1,200 and 1,500 TR modules for the J16 rather than the 1,760 figure.J16采用了Su27BS機(jī)身設(shè)計(jì)，從容量方面看，與F15和F22相同（Kopp，2012）。提赫米洛夫儀器制造研究院制造的N036 AESA雷達(dá)系統(tǒng)擁有1500個(gè)T/R組件，與電子掃描陣列（ESA）IrbisE雷達(dá)（無(wú)源相控陣PESA）孔徑尺寸相似，后者在與Su27機(jī)身結(jié)構(gòu)設(shè)計(jì)相仿的Su35上使用。如果說(shuō)裝備J16的AESA雷達(dá)確實(shí)擁有1760個(gè)T/R組件，那么這將說(shuō)明中國(guó)航空工業(yè)在T/R組件封裝技術(shù)方面已經(jīng)超越俄羅斯，因?yàn)镹036雷達(dá)據(jù)信已是目前俄羅斯戰(zhàn)機(jī)裝備的最先進(jìn)AESA雷達(dá)系統(tǒng)。相類(lèi)似地，最先進(jìn)的美式戰(zhàn)機(jī)所裝備的APG77(V)2 和APG82(V)1雷達(dá)同樣擁有約1500個(gè)T/R組件。通過(guò)兩代AESA系統(tǒng)設(shè)計(jì)，中國(guó)航空工業(yè)技術(shù)水平趕超美國(guó)和俄羅斯同行的可能性值得懷疑，因此，作者懷疑1760個(gè)T/R組件的信息源于對(duì)未經(jīng)證實(shí)圖片的武斷猜測(cè)，因而造成了J16 AESA系統(tǒng)比美國(guó)和俄羅斯最先進(jìn)AESA系統(tǒng)多260個(gè)T/R組件的說(shuō)法。據(jù)此，作者推測(cè)，裝備J16的AESA雷達(dá)系統(tǒng)大約擁有1200至1500個(gè)T/R組件，而不是網(wǎng)傳的1760個(gè)。Image 5: The sixth and most recent (as of January 2015) unveiled J20 testing aircraft model 2015.圖5：最新曝光（2015年1月）的第六代J20測(cè)試驗(yàn)證機(jī)（代號(hào)：2015）。The tentative designation for the J2039。s AESA is the Type 1475. While the nose volume of the J20 is certainly large, the jet overall is longer and heavier than the F22, no credible figures for nose volume were available at the time of this publication. As with the J16 T/R figure, the J20 figure is substantially greater than that of the most advanced US and Russian designs. Even if the Nanjing Research Institute of Electronics Technology (NRIET) or the China Leihua Electronic Technology Research Institute (607 Institute) was able to develop sufficient packaging technology that would enable 1,856 T/R modules within the J2039。s nose, the density of the T/R modules would cre
