reading your comments i had mixed response of ANGER as well as amusement,lemme clear some of your doubts-
PLEASE READ THIS
I agree,that HAL had been rather sluggish in past,especially till late 90s,the weapons development programs were sluggish and victims of bureocracy till atleast late 90s,but partly it was because of lack of “manufacturing base in india in 80s and 90s”,things have improved “tremendously” starting from 2000s,
now the time required by HAL/DRDO to produce a new technology has reduced to a great extent,as can be seen in various recent examples,like AGNI-5,TAL,LCH,DHRUV,etc etc,
this has been made possible due to “established manufacturing bases and r&d centres”,the country now proudly boasts of many pvt sentor players which have massive manufacturing capabilities and research centres
now I will address major issues-
ENGINE-
well the GTRE’s kaveri engine program has been criticized a lot by all corners,but hardly any of those ever tried to delve into the complexities involved in designing and manufacturing a turbofan engine from scratch..i will try my best to write things based on proper engineering knowledge..
1)designing and developing an efficient,modern turbofan engine with sophisticated FADEC control is awefully challenging task,infact developing a turbofan engine MORE complicated than developing a GSLV rocket(mind you,an indian GSLV MARK-3 rocket can put 5 tonnes into geo synchronous orbit!!)..it is many more times challenging than developing the jet itself…it requires really serious research in metallurgical engineering for years and decades together,
Indian kaveri engine has been perfected over the years and now it proudly boasts of thrust of 82-85kN,however it still falls short of IAF’s GSQR which demands atleast 95kN of thrust in LCA tejas…
this doesn’t limit it’s applicability,and infact IAF has decided to use this engine in less demanding areas like powering UAVs,UCAVs,trainers etc
a marine gas turbine derived from kaveri is already powering Indian naval ship (INS RAJPUT),called KMGT,rated at 12MW(almost 17000hp),
SO overall,the kaveri project has given a positive gain to Indian industry and it has potential to be exported to countries which are looking for gas turbine options to power their naval ships with tonnage lesser than 6000tonnes…
the intellectual property right of kaveri engine belongs to india and all the parts are manufactured in india
..:: India Strategic ::.. Kaveri engine’s naval version doing fine
