(1) 恕我直言,你反复将Y10与IL76比,我认为是不恰当的!
不可否认,IL-76MD作为大型军用运输机,MTOW=190吨,空机重92吨,
最大燃油90吨,最大载重50吨,确是一种较好的运输机。但不要以为
俄罗斯用IL76改成A-50,就认为只能用IL76改预警机,别的飞机就不
行!看看美国,为什么不用C-17(MTOW=265.351kg)改预警机?为什么
还要用737-700(MTOW:STD=60.32吨,Option=70.08吨)改预警机?
(2) 你对707的评价有失公允,707作为E-3、E-6、E-8载机已经多年
使用考验,至今仍是美国、法国、英国、沙特和NATO的主力预警机队。
海湾和科索沃战争大量使用。
下面是Boeing网上资料(节录):
Military Derivatives
Yet another aircraft type that traces its ancestry to the
707 prototype is the U.S. Air Force KC/C-135 tanker-
transport/cargo airplane. Boeing built 820 of these aircraft
for the Strategic Air Command and the Military Air Transport
Service (predecessor of the Military Airlift Command).
The KC/C-135 series was initially designated within The
Boeing Company as the model 717. In January 1998, the 717
model number was reassigned to the commercial line for the
717-200 regional jetliner.
Additionally, three 707-120s plus two 707-320Bs, designated
VC-137s, were delivered to the Military Airlift Command for
transporting high government officials. These 707s
transported the President for more than 30 years until
replaced in 1990 by two 747-200s designated as VC-25s.
Recent military applications of the 707 are the E-3 Airborne
Warning and Control System or AWACS (used by the U.S. Air
Force, NATO, the Saudi government and the French and British
air forces for airborne surveillance, command and control)
and the E-6 used by the U.S. Navy for submarine communications.
When the 707 production line was closed at the end of May 1991,
Boeing had sold 1,010 of all types (not counting the KC-135
series).
(3) Y10与Y7、Y8和MA60的比较:
Y10是110吨级涡扇动力大型运输机,采用早期的JT3D-3B(油耗较大)
满客航程6400公里,5吨商载航程8300公里;如采用某先进涡扇,
18.15吨商载航程7370公里,最大燃油航程(对应商载4.47吨)
11036公里。Y10飞机巡航速度M=0.82(11887米,871km/h;10668米,
875km/h;9449米,891km/h)。
zergling先生,你说707和Y10不如新舟60,请将新舟60的数据列出来,
也好让网友们来评论。
笔者必须申明,Y7、Y8和新舟60都是我们的国产飞机,对它们的应用
潜力也应充分挖掘。因Y10而排斥Y8,或因Y8而排斥Y10均不可取。
我不希望在讨论Y10的发展潜力时伤及Y7、Y8和新舟60。我在前面贴子
中的一段话出自最近刚从乌克兰出差回来的朋友,也许,这番话确实
该引起我们的深思。
(4) 你所提出的问题:“另外,我想问你们几个问题:我国空军的经
费才多少?整体装备水平又怎样?有可能装备上百架加油机和预警机
吗?除了Y10以外,空军是不是还有其他更好或是更经济的选择?空军
近几年有没有以任何形式表达过对Y10的兴趣?”本人无可奉告,并希
望你以后最好不要提出类似问题。
