J-20★ 2015 First Flight J-20★2015第六架原型机首飛 The 6th J-20 stealth fighter takes off on December 19, 2014 in Chengdu, China. The rapid production of J-20 prototypes (4 so far) this year suggests that the fighter is well on its way into production. On December 18, 2014, the 6th J-20 stealth fighter prototype took off from the Chengdu Aviation Corporation factory. At six airframes, that makes the J-20 the most numerous non-American stealth fighter in the world (the Russian T-50 PAK-FA has only four airworthy examples, after an accident in June 2014 destroyed the fifth model). So far, 2014 has seen the debut flights of four J-20 fighters (2011, 2012, 2013 and 2015). 2015 in Flight 2015 made its first flight on December 19, 2014. At this point in the J-20s development, the design is essentially fixed, though the AL-31 engines are likely to be swapped for more powerful Chinese WS-15 turbofans by 2019. Coming less than three weeks after the fifth prototype, 2013, first flew on November 29, 2014, the rapid production of J-20 stealth fighters suggests that Chinas flagship fighter program is entering Low Rate Initial Production (LRIP). LRIP is the stage in the development of military platforms where the design is essentially frozen, thus allowing the manufacturing to begin gaining experience by producing small numbers of the finished design (the F-35 is currently on LRIP Batch 8). The rapid production of four similar fighters within a year suggests that China has settled on the final design of the J-20, and it is likely that production of the first squadron could happen in 2015. The first squadron of 20-24 fighters would be produced in 2015 and early 2016, going to the China Flight Test Evaluation Regiment to develop tactics for the J-20s advanced capabilities. Assuming things go to schedule, the first J-20 squadron would be ready for combat in 2017. J-20 Radar Testbed sina This fan made comparison shows the Tu-204 769 airliner modified for use as the J-20s radar testbed, along with its American Boeing 757 counterpart which tested the F-22As radar. The grey panels beneath 769s cockpit could be smaller side and rear mounted radars for the J-20, to provide 360 degree coverage. Like the F-22, the J-20 will have an AESA radar capable not only of detecting enemy radars and guiding missiles, but also it can jam enemy electronics, communications, as well as conduct intelligence gathering and processing. J-20★2015年首飛 December19日歼20首飞第六架原型机首飞，而这距离第五架原型机2013号的首飞仅仅相隔20天而已。 有消息称，2015号原型机是和2016号同时开铆制造的(2012和2013的出现时间也很接近)那么2015号出现后，2016号的曝光想必也为期不远。届时即使不计算2001和2002两架验证机，歼-20试飞用原型机的数量也将达到5架。这5架原型机今明两年相继投入试飞，将大大加速歼-20的服役进程。 J-20的雷達測試平台 sina 此風扇做對比顯示了圖-204“769”客機改裝用作J-20的雷達測試平台，以及美國波音757對應其測試的F-22A的雷達。下面769的駕駛艙的灰板可以是更小的側和後置式雷達為J-20，以提供360度覆蓋。像F-22，J-20將有AESA雷達不僅能夠探測敵方雷達和導彈引導，也可以干擾敵方電子，通信，以及進行情報蒐集和處理。 在2015年飛行 2015年進行了首次飛行於12月19日，2014年在這一點上，在J-20的開發，設計基本上是固定的，雖然AL-31發動機很可能在2019年被換成更強大的中國的WS-15渦扇發動機。 未來不到三週的第五原型後，“2013”，首飛於2014年11月29日，快速生產的J-20隱形戰機表明中國的旗艦戰鬥機項目已進入低速率初始生產（LRIP）。 LRIP是在那裡的設計基本上是凍結的軍事平台的發展階段，從而使製造業開始由生產少量的成品設計積累經驗（在F-35是目前LRIP批次8）。快速生產四個類似的戰機在一年內表明，中國已經解決的J-20的最終設計，並且很可能是生產第一中隊會在2015年發生的20-24戰鬥機的第一個中隊會在2015年和2016年年初生產的，要到中國飛行試驗評估團制定戰術的J-20的先進功能。假設事情安排，第一J-20中隊也準備好戰鬥在2017年。 youtu.be/m0y5-rMaLK0
