Breakthrough for Kaveri engine, Clears Audit for Aircraft Integration
According to information provided by DRDO in it’s Anual Report for 2017, Five Kaveri engine prototypes K5, K6, K7, K8, and K9 were tested for about 145 hours in total in 2017 during which some critical and several tests like a transient test from idle to max reheat conditions were carried out for the first time successfully .
The Kaveri project – which was abandoned in 2014 as it did not meet the power requirements of the Air Force – is being revived with French help for use on both the indigenous Light Combat Aircraft (LCA) and a new unmanned combat aerial vehicle (UCAV) project.
Under the terms of the partnership finalised late last year, Snecma is working to modify, certify and integrate the Kaveri on a Light Combat Aircraft airframe before 2020. A later phase in the partnership will involve modifications on the Kaveri for a twin configuration on India’s AMCA fifth generation fighter concept and an altered non-reheat version for the Ghatak UCAV. It is not clear if the Snecma partnership will stretch to the concept Manik mini-turbofan being developed for UAVs and cruise missiles. One of the Kaveri specimens was on display at the recent Aero India show.
According to the report submitted, Safran completes technical audit of Kaveri jet engine prototype in France
Report said that the engine had attained sufficient maturity to be integrated with an aircraft for limited envelope flight testing.
DRDO Chief Dr S Christopher in 2017 had said that LCA-Tejas will fly with Indo-French Kaveri engine by 2019 Aero India
Kaveri engine reportedly will be able to generate 88.9 kN to 99 kN of Thrust with afterburner .
It is also planned to use an upgraded version of Kaveri to meet the needs of the Advanced Medium Combat Aircraft (AMCA)
This implies that the Kaveri turbofan should be upgraded to generate 110-kN wet and 75-kN dry thrust. But then an engine of this capability will need to incorporate single crystal blade technology, integrated rotor disk and blades and super alloys of nickel and cobalt. Kaveri engine in its present form uses directionally solidified blade technology which is rather an old hat. The 20-tonne class AMCA designed for stealth features and super cruise capability is planned to be powered by two GTX Kaveri engines. Significantly, the Kaveri engine has been custom built to operate in the demanding Indian environment that ranges from the hot desert to the freezing mountain heights.
Kaveri Engine For SU-30MKI
AL-31F engines on Sukhoi-30MKI fighter jets will save India from the exorbitant amount of money which India needs to pay to Russia for Transfer of Technology license agreement for developing AL-31F engines in India and also to remove the problematic engine it self which keeps the operational availability of the entire Sukhoi-30MKI fleet lower than 65% in Indian air force.
