印度Kaveri引擎的剩餘價值
根據在1987年4月建立的「導彈及其技術控制制度」(Missile Technology Control Regime)，任何可以攜帶一個最低有效載荷500公斤，最低為300公里的無人運載系統的技術是受到嚴格監督。雖然最初的目標應該是抑制核彈頭運送技術的擴散，這制度事實上也限制了可以使用於大型無人機的引擎的出口。印度有自主知識產權的Kaveri引擎，但其他較小的國家很難發展自己的引擎用於自製的大型無人機...

Original Title: India's Kaveri Engine - Good For Something?
India's indigenously developed Kaveri engine may be unfit to power the country's Tejas Light Combat Aircraft (LCA) - itself not a stellar performer - but it has found a new home.
On Dec 10, in written reply to a parliamentary question, defense minister AK Anthony says a derivative of the Kaveri can power India's Unmanned Strike Air Vehicle (USAV), planned to enter service by 2020.

According to the Business Standard, India has no choice but to use a dry (unreheated) version of the Kaveri in the USAV because the international Missile Technology Control Regime bars the export of engines for unmanned aircraft with ranges more than 300km.
Under development by India's Gas Turbine Research Establishment (GTRE), the Kaveri's afterburning thrust is less than designed and well short of that needed to power the overweight LCA, but its dry (unreheated) thrust is adequate to power the under-10-tonne USAV, the report says.
The Business Standard says tests at Russia's Gromov Flight Research Institute, mounted on an Il-76 flying testbed, showed the Kaveri's afterburning thrust is 15,800lb, versus the planned 18,200lb. But dry thrust was almost 11,100lb, close to the planned 11,500lb.

The Kaveri has been under development at the GTRE since March 1989. Anthony, in his written reply, says 2,200hr of ground and altitude testing have been completed on nine Kaveri prototype engines plus four Kabini core prototypes. In Russia, the engine was flown to Mach 0.7 and almost 40,000ft over 27 flights totalling 57hr.
Development was scheduled to be completed in December 1996 at a projected cost of $69.5 million (Rs.382.81 Crore). But because of technical failures and delays, the program was extended and its cost revised to $515 million, of which $362 million has been spent so far, says Anthony.
Because of the Kaveri's failure, the Tejas Mk1 is powered by an imported 19,000lb-thrust GE F404-IN20. But the aircraft is overweight and underpowered, so an enlarged Mk2 version is planned powered by a 22,000lb-thrust GE F414-INS6.
India's USAV, meanwhile, looks a lot like Europe's Dassault-led Neuron unmanned combat-aircraft technology demonstrator (below), which made its first flight in France in early December. The Neuron demonstrator is powered by a 9,000lb-thrust Rolls-Royce Turbomeca Adour.Source: Aviation Week Blog

原本就是為了自製輕型戰機要用的~
反正學費也繳了，重點是技術要有學到...
倒是印度真的要搞無人機用Kaveri引擎~
我看.....{:51:}
又要搞十幾年嗎?? 一個很大疑問印度真的有能力做引擎嗎 戰機都攪不好了 印度想弄點成績出來，但是總是有些無力！{:51:}
別的國家有了什麼，他就想搞什麼{:40:}
還是按部就班的好！ 還真有點懷疑她們的技術中國每年軍事預算逐年增加
不過真的要跟美國比還有段距離<br><br><br><br><br><div></div> 這引擎研發這麼多年了，也做不出個甚麼東西，真的是在搞笑... 印度人多 人才也會多
一定會搞出個什麼來吧
俄羅斯估計中國光是航空母艦投入的資金應該超過印度20億美金,不論從本國或是外來技術的發展及吸收都是促進中國軍事超越印度的因素.{:32:}
