GTRE GTX-35VS Kaveri
afterburning turbofan aircraft engine
The GTRE GTX-35VS Kaveri is an afterburning turbofan project under development by the Gas Turbine Research Establishment (GTRE), a lab under the Defence Research and Development Organisation (DRDO) in Bengaluru, India. An Indian design, the Kaveri was originally intended to power production models of the HAL Tejas developed by Hindustan Aeronautics Limited. However, the Kaveri programme failed to satisfy the necessary technical requirements on time and was officially delinked from the Tejas programme in September 2008. As of 2025, a dry variant of the Kaveri engine is now being developed to power the DRDO Ghatak.
History
Programme
In 1986, the Indian Defence Ministry's Defence Research and Development Organisation (DRDO) was authorized to launch a programme to develop an indigenous powerplant for the Light Combat Aircraft. It had already been decided early in the LCA programme to equip the prototype aircraft with the General Electric F404-GE-F2J3 afterburning turbofan engine, but if this parallel program was successful, it was intended to equip the production aircraft with this indigenous engine.
The DRDO assigned the lead development responsibility to its Gas Turbine Research Establishment (GTRE), which had some experience in developing jet engines. It had developed the GTX37-14U after-burning turbojet, which first ran in 1977, and was the first jet engine to be designed entirely in India. A turbofan derivative, the GTX37-14UB, followed. The GTRE returned to turbojet technology with the greatly redesigned, but unsatisfactory, GTX-35.
Begin with the source’s own compact description: “GTRE GTX-35VS Kaveri” is afterburning turbofan aircraft engine. The dossier treats that line as a proposition to test through GTRE, GTX-35VS and Kaveri, not as a finished interpretation.
Why this record matters
The phrase “afterburning turbofan aircraft engine” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 17, 2026. The linked authority identifier is Q3595564. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2008, 2025, 1986 and 1977.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
