well, it is a letter of thanks to Beihan University from CAC(Chengdu aircraft CO,the manufacturer of Chinese 5G bird). The letter leaked indeliberately that under the help of Beihan Univ., CAC funished all tech integration of " the project" on May,2010 and two prototypes were assembled on Octo 14th, 2010 Beihan University is Chinese top R&D center of Chinese space&aircraft tech.It helped a lot CAC with the R&D of Chinese 5G bird. So, CAC open this letter of thanks to Beihan University. the following is my rough translation. BTW, the letter was firstly posted on the offical website of Beihan University ,then reposted on CD . Usually, the news from CD is always confirmed by Janes and Kanwa half an year later! haha lastest news: the letter on the offical website of Beihan University has been censored.(en, somebody who is responsible to the indeliberate leak must be f^cked by Chinese national security now.....) here is the censored link: http://news.buaa.edu.cn/dispnews.php?type=4&nid=74785&s_table=news_txt Lastest news: some students from Beihan University confirmed on CD that the major of Prefessor Zhang Deyuan is just the Ultrosonic vibration cutting" Last news: here is the brief introduction of Professor Zhang Deyuan on the official website of Beihan University http://sae.buaa.edu.cn/Show/ViewP.aspx?PageMethod=SetDocu&DocuID=35 Lastest news one picture of 5G bird was posted on CD...I don't know if it is PS,but it seems not bad. BTW, according to CD,the NO. of the prototype is "2001" and the first taxi run of the prototype was successfully finised on November,5th,2010. Last news: According to one "insider" who is active on CD, the prototypes of Chinese 5G bird are ready already,whether the abover picture is PS or not. BTW, it was the "insider" that first leaked the finish of J15 on Oco,2009,which was almost half one year before Kanwa and Janes comfirmed it. the "insider" leaked that â€œThe count-down now has started " on CD on Octo 30th, 2010. Lastest news: the Cockpit of CHinese 5G bird? it is the cockpit showned in ZHuhai aircraft Exhibition. It is widely reported to be the cockpit of CHinese 5G bird BTW,the cockpit is quite similar with one picture shown in another arm exhibition in Beijing last year last news: Last news: Janes Defence reported that Chinese 5G bird to fly by the end of 2010 well, this time, Janes Defence is only 2 months later than CD .It seems that CD also becomes information resource of Janes now.hahaha. hahah. Last news: CD now is boiled by one leak that CHinese 5G bird has tested its first high-speed taxing. somebody even posted one picture of 5G bird so called.
