主题：印度要请波音帮助把LCA收尾？ -- 晨枫
花钱买教训，就是代价太高了些，不比我们以前“交学费”便宜。
最大的问题是航程太短。不过这都不是印度最大的问题，印度最大的问题就是如何利用现在这个“窗口”，尽可能从美国和欧洲获得现金装备。俄罗斯装备什么时候都可以买到，但欧洲装备对印度的开放不是无条件的，也没有“友谊价”这一说；美国装备这是第一次开放。这才是印度肯定舍俄求美欧的道理。
改进后的米格29SMT还是比较先进的，除了机体尺寸比Su-27小以为，已经很接近了。
但是米格29的问题还是在于相对落后的克里莫夫发动机，这么多年进步有限，如果有与AL31F技术水平类似的发动机，米格29SMT就如虎添翼了
发动机推重比只有6.5，这就注定了米格-29的前途暗淡，那么多重量本来可以用来装载燃油或者电子设备的。
而且寿命极短、黑烟严重~
简直就像发动机着火了一样，看着可怕。
现在基本都不用注明，老远就知道是Mig29了：）
最可笑的是最后两段，一如既往，眼看拉不开栓了，赶紧给ＬＣＡ定了个新的交付日期。ＬＣＡ的故事就沿着这条循环的轨道继续走下去。

正文：
BANGALORE: The Indian Air Force has categorically ruled out placing further orders for the indigenous Light Combat Aircraft (LCA), Tejas, with its current configuration.印度空军斩钉截铁地排除了进一步采购现行结构的ＬＣＡ。
In 2005, the IAF placed an order with Hindustan Aeronautics Limited for 16 fighters and four trainers. The then Defence Minister Pranab Mukherjee said a decision on an additional 20 aircraft was under consideration. But that plan has come a cropper since the overweight, under-powered Tejas does not meet the IAF’s minimum air staff requirements (ASR).
The IAF decision though is not the end of the road for the Rs. 6,000-crore LCA programme. It will consider acquiring 125 more Tejas when an improved — Mark 2 (Mk2) — variant is developed. As indicated by an IAF committee in 2004, any further order will be subject to the Aeronautical Development Agency (ADA), the designer and developer of the LCA programme, showing “firm visibility that the aircraft will meet the ASR.”
Recently, the IAF even made a few suggestions on improvements in Tejas Mk2, including a more powerful engine, optimisation of the aerodynamic qualities and weight of the aircraft and “dropping and replacing” certain parts to take care of obsolescence.
Tejas Mk2 will take a few years to fructify, the biggest challenge being choosing a new powerful engine. In December, the ADA is expected to issue a request for proposal to General Electric for its GE F414 and to the European consortium Eurojet for EJ200, in a bid to procure 99 engines (with an option to buy another 49).
Once the engine is chosen, fuselage modifications will have to be carried out, flight tests started and evaluation undertaken. All trainer aircraft even after Tejas Mk2 rolls out will continue to have the present GE F404 engines.
Cold weather trials
On the LCA programme, the ADA is getting ready for ‘cold weather trials.’ They were to have been conducted in 2007 but were not because of questions about the aircraft’s reliability.
Two or three aircraft are scheduled to leave for Leh on December 8. Cold weather trials include landing the Tejas at Leh, one of the most challenging airfields in the world, and ‘cold soak’ when temperatures are around minus 15 degrees C to see if the systems on board function normally.
Slow pace
The IAF is also worried about the slow pace and quality of work at HAL. More so, because it will not be able to deliver by 2013, as scheduled, the 20 aircraft for which orders have been placed. Defence Minister A.K. Antony recently said the Tejas would enter squadron service by 2011, which date, according to officials, is highly optimistic as hardly 10 or 12 test sorties are now being undertaken. The IAF expects the final operational clearance for the Tejas only after 2012.
我在写起而不飞的时候，差点把这个事写进去了。想想不大厚道，别乌鸦嘴，结果还真就是这么回事。这老印啊，真叫人看笑话都不好意思。
他这“世界上最严酷的低温机场”Leh的温度才零下15度，那加拿大空军岂不全该冻在地面上了？零下15度，要是有太阳，那是拖出躺椅sun tan的日子啊。呃，这个说得夸张了一点，不过零下15度怎么也算不上低温试验的，当然，除了在印度。
换用F414或者EJ200，看来还是要基本保留原机体，只是放大到足够装型发动机，用增加的推力来补偿原来的超重，否则推重比还是不够。这样一来，机内载油量还是上不去，而加大的发动机的绝对耗油增加，航程更加小了。这Mk2还是够呛。
我说，干不了，找你们湿婆老大去吧思密达
EJ200长4m，直径737mm，而F404-GE-402长3,912 mm，直径889 mm，用EJ200替换F404应该不算太难，主要是管线的配合问题。
而F414的外形尺寸与F404一样（我也比较奇怪，实在Wiki中查的）
进气道的流量会不会要增大啊？那还是要重新设计机身啊。
没有找到特权威的资料。EJ200是75~77kg/s，F404是49kg/s。
这样做出来,换一新发动机,连带的机体设计.燃油问题.那是多大的工程?
其实换差不多的发动机.象歼八把wp14换昆仑那种换法才有意义.气流量不增加.基本尺寸差不多.那才有用.印度这样来,那就肯定就是重新来一个.要是还这样搞,三十年后还是盼望LAC飞起来!
