NEWS ON KAVERI ENGINE

The Indian government today provided a comprehensive update on the indigenous Kaveri turbofan programme. Here it is, in full:

(i) All major engine sub-assemblies have been tested for aerodynamic performance and structural integrity (life & safety) requirements from qualification point of view.

(ii) Critical sub-systems have been developed.

(iii) Full authority Kaveri Digital engine Control System (KADECS) has been designed and developed.

(iv) Various critical technologies in the fields of instrumentation/measurement, health monitoring, data acquisition, etc. have been developed.

(v) Twelve materials (Titanium, Steel and super alloys) have been developed and type certified.

(vi) Directionally Solidified (DS) casting technology and high temperature tip brazing technology for the High Pressure and Low Pressure turbine blades & vanes have been developed.

(vii) Adequate manufacturing technology base has been established.

The reasons for the delay in developing the said engine are as follows:

(i) Non-availability of critical materials, viz., nickel and titanium based alloys in the country............The matter is now solved for the news says..................." Twelve materials (Titanium, Steel and super alloys) have been developed and type certified "

(ii) Low priority from foreign manufacturing agencies in view of the Minimum Order Quantity (MOQ) vis-à-vis the production order quantity from other engine houses.

(iii) Lack of manufacturing infrastructure for critical components.

(iv) Flying Test Bed (FTB) trials were not originally envisaged but included subsequently, based on the recommendations of Certification Agency and IAF.

(v) US sanctions imposed during 1998 affected the delivery of critical systems & components.

(vi) Lack of infrastructure of engine testing and component / system level testing within the country leading to dependency on foreign agencies.

Kaveri engine testing under simulated altitude and forward speed conditions during February 2010 has been successfully completed. Another engine has been integrated with IL-76 aircraft at Gromov Flight Research Institute (GFRI), Moscow for ground and flight test which is expected to complete by October 2010 (sic). These two major milestones would make 'Kaveri' engine certified for flight operations. Productions of LCAs are, meanwhile, as decided by user, being fitted with imported engines.

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.
