India can make 80kN Combat Jet Engine

We all know that the engine development has been Achilles’ heel of the Indian Aviation sector. Reason is simple, we have not invested enough, and government has not prioritized the development of engines as import always seems to be an easy option. The present-day problems in the Indian Defence manufacturing sector are the by-product of the Indian government policies in the past.

Anyways, coming back to present. So, recently replying to the question of media, the Minister of State for Defence Ajay said that “Indigenous capability exists with DRDO & Industries for design, development & manufacturing of 80KN combat jet engine. Collaboration with a foreign house is being expected for co-development and co-production of higher class thrust engines for AMCA. The cost including the transfer of technology for the manufacturing of the jet engines can be known after further progress”

The engine which is being referred is the indigenous Kaveri engine developed by GTRE of DRDO. These kinds of generic statement have been making news either by defence secretary or by defence minister or by DRDO Chief for more than an year.

Issues with the Kaveri Engine

Talking about the Kaveri Engine, In past the engine had several problems which has been resolved completely and few of them needs to be flight tested at higher altitudes. One of the major issues with the Kaveri engine was the flutter of fan blades. Flutter was related to all the blades used in the engine. Various methods have been deployed to successfully resolve the flutter issue. Other issues with Kaveri engine related to fan, HP Compressor, LP Turbine, combustor, after burner and screech issue has also been resolved.

Future plan of GTRE

While Kaveri engine has met its dry thrust requirement, it is yet to prove its wet thrust. GTRE has planned the Performance and operability of Kaveri engine across the flight envelop in altitude test facility in 2022. The initial flight release (IFR) certification of the engine is planned to be completed by 2024. However, the Russia-Ukraine war seems to derailing this plan again due to India’s dependence on Russia for the FTB for Kaveri engine. Indian government need to spend at least a billion dollar every year in order to master this technology.

AMCA engine by 2035

At the same time, the French aircraft engine manufacturer Safran has submitted a proposal to the Indian government to co-develop with DRDO’s Gas Turbine Research Establishment (GTRE) a new state-of-the-art 110 kilo newton thrust engine for India’s futuristic AMCA twin-engine fighter jet project.

The Safran deal includes a performance guarantee and transfers all necessary technology for design, advancement, production, and support, in addition to building a solid industrial aero-engine environment in the country.

If the co-development process is all cleared this year, Safran is confident that the new 110 KN engine could be certified by 2035. The 110 KN engine’s co-development will be a total of between five to six billion euros.

The engine created for the AMCA will probably have many similarities with the propulsion system of the upcoming sixth-generation FCAS fighter in Europe, for which SAFRAN is the part of multi-project leader (Spain, France, and Germany).
