Aero-space Engines – The Defence Research and Development Organisation (DRDO) has announced a modest step towards achieving the ultimate aeronautical challenge, one that even resource-rich China has struggled to accomplish: developing a jet engine that is powerful enough to power fighter combat aircraft.
“The Department of Defence (DRDO) establish a near-isothermal forging method for the construction of HPC discs, which is produce with their unique 2000 MT (metric tonnes) isothermal forges, according to the Ministry of Defence (MoD).

What’s more in Aero-space Engines?

In DRDO’s premier metallurgical research facility, the Hyderabad-based Defence Metallurgical Research Laboratory (DMRL), complex titanium and nickel-based alloys have been developed.
Indian manufacturers have joined a select group of global engine developers capable of manufacturing such critical components.
In a fighter jet engine, the air is suck in, compress quickly, aviation fuel is inject, and the mixture is ignited to create high pressure and high-temperature gas. The exhaust is expel backward, propelling the aircraft forward as its reaction takes place.

The seven primary components of jet engines, from front to back, are the intake fan, low- and high-pressure compressors, the combustion chamber, turbines, and exhaust pipes.

Finely tuned design and manufacture are in requirement for aero engines. Over the past three decades, the Gas Turbine and Research Establishment (GTRE) in the DRDO have led a multi-laboratory effort to design the Kaveri aero-space engines, but results have been disappointing.
I believe (Kaveri) project was sanctioned in March 1989 with an estimated cost of Rs 382.81 crore. Also a Probable Date of Completion (PDC) of December 1996. However, AK Antony, Defence Minister, told Parliament on December 10, 2012. “We have extended the PDC to December 2009, and increased the cost to Rs 2,839 crore.

Achievement by Kaveri

Kaveri has achieved a thrust of just about 65 Kilo Newtons (KN), well short of the 95 KN of its premier rivals. The Eurojet EJ200 and the General Electric GE-F414. As a result, the DRDO has decided to explore the possibility of using the Kaveri in warship propulsion.

DMRL, which developed the technology for aero-space engines to produce the five-stage HPC discs. It is a lab that does not have the facilities to produce large quantities.

Therefore, to manufacture discs in the volumes required, DMRL has licensed technology for aero-engines to defense public sector undertaking (DPSU). Midhani through a licensing agreement for technology transfer (LAToT).

“DMRL and MIDHANI have jointly produced 200 HPC disc forgings about various compressor stages. It was by utilizing the isothermal forge press at DMRL, Hyderabad. In Bengaluru, HAL’s Engine Division has received these gearboxes for use in its Adour 804/81. Also 871 engines that power Indian Air Force aircraft (IAF’s) Jaguars and Hawks.

Rolls-Royce, the original equipment manufacturer (OEM), licenses HAL, Bengaluru, to overhaul the Adour engine. They must replace the HPC Drum assembly regularly, so their annual requirements are extensive, justifying indigenization for higher export revenues.

By the requirements of airworthiness agencies, HAL HPC Discs is in approval. A letter of technical approval (LoTA) has been in issue for the technology as a result.
