DRDO Says Kaveri Engine Can Power Combat Drones 80 KN OF Thrust Available Now

DRDO officials say the Kaveri aero-engine, which incidentally is over 22 years in the making by now with a sanctioned cost of Rs 2,893 crore, can power unmanned combat aerial vehicles (UCAVs) because they "do not require the kind of higher thrust" needed for the indigenous Tejas LCA (light combat aircraft).

" Nine prototypes of Kaveri engine and four prototypes of Kaveri Core (Kabini) engines have been developed with over 2,000 hours of testing...the engine is proven with almost 80 kilonewtons (kN) of thrust now, which is enough for our UCAVs (Tejas requires 90 kN)," said an official.

This comes even as DRDO has now begun preliminary work on developing stealth UCAVs, under the secretive 'autonomous unmanned research aircraft' programme. This UCAV will weigh less than 15 tonnes, fly at altitudes of 30,000 feet and fire missiles and bombs with precision, as earlier reported by TOI.

DRDO has also come up with a modified Kaveri version, by "designing a free-power turbine to generate shaft power", for propulsion of warships. The Navy, as per DRDO, has shown "a lot of interest" in the engine which has a 12 MW power output.
"With Kaveri, we have proven several gas turbine technologies for a variety of applications. Indian Railways is also interested in knowing whether Kaveri can be used for powering trains," said the official.

DRDO is now also trying to tie up with French company Snecma to jointly develop the "90kN thrust class of upgraded Kaveri engines" for the future requirements of IAF. But the fact remains that the Kaveri project's dismal performance has forced India to ink a $822 million contract for 99 General Electric's F-414 engines, with an option to go for another 49 engines at a later stage, to power the Tejas Mark-II version.

While the first 20 Tejas will be powered by GE-404 engines, the next six Mark-II squadrons (16-18 jets in each) will have the new more powerful GE F-414 engines. Under the LCA project, which itself has been 28 years in the making with an almost 3,000% jump in overall developmental costs, IAF hopes to have its first two fully-operational Tejas squadrons based at the Sulur airbase (Tamil Nadu) by 2015 now.

Pakistani JF-17 A Thunder OR A Blunder

Pakistan has witnessed new defense acquisitions in this decade than any other, and in the center of it all is the new fighter which was designed by China with partial funding from Pakistan. It is formally known as JF-17 Thunder. When the fighter was in development, Pakistani online communities were jumping with excitement comparing it with its arch rival India’s modern combatants Su-30MKI, Mig-29S & Mirage-2000H. There were claims of it featuring western Radars and long range missiles, & Chinese ordering some due to its superior capabilities. But the reality is far from it. China having spent significant amount of money into a fighter which it is never going to use, most probably forced Pakistan to accept its avionics to offset some its development costs. Chinese who are known for their self reliance first and quality next, are further downgrading JF-17s capabilities with their poorly copy-pirated avionics. Along with their dubious weapons, any chance of JF

Pakistani F-16s Shoot Down RAF Eurofighter Typhoons During Air Combat Exercises In Turkey

Pakistani pilots flying modernised versions of the 1970s-vintage F-16 Falcon fighter have beaten the RAF's brand-new Eurofighter Typhoon superfighters during air combat exercises in Turkey, according to a Pakistani officer. Analysis: The RAF Typhoon, formerly known as the Eurofighter, should nonetheless have been vastly superior in air-to-air combat whether BVR or close in within visual range (WVR). The cripplingly expensive, long-delayed Eurofighter was specifically designed to address the defects of its predecessor the Tornado F3 – famously almost useless in close-in, dogfighting-style air combat. The Typhoon was meant to see off such deadly in-close threats as Soviet "Fulcrums" and "Flankers" using short-range missiles fired using helmet-mounted sight systems: such planes were thought well able to beat not just Tornados but F-16s in close fighting, and this expectation was borne out after the Cold War when the Luftwaffe inherite

India Planned Attack On Pak Navy Mehran Base To Kill Chinese Engineers

The terrorist attack on Karachi's Mehran Naval Station on May 22 was conceived and launched by India with the primary objective of killing the Chinese engineers present there, a Pakistani newspaper has claimed, citing 'informed sources'. Four to six Taliban terrorists had entered PNS Mehran on May 22, destroying two maritime surveillance aircraft and killing ten military personnel during their 17-hour siege of the naval air base. "India is the only country in the region that feels troubled by the Pakistan Navy, which had awfully beaten the Indian Navy in Operation Dwarka of 1965. Since then, it has been an earnest desire of India to harm the Pakistan Navy but it was perhaps not possible on the battle front, hence it struck the PNS Mehran," The News quoted sources as saying.
