HAL HTFE-25 & Other Indigenous Aero Engines Developments

Gautam said:
HAL is utilizing the established but limited facilities at NAL, GTRE and other DRDO labs for testing combustor, gas generator turbine, electronic components etc. However we do not have the facilities in the country to test compressors, HP turbines, power turbines of the order of 1 MW and above with matching speeds. Flying test bed and altitude test benches are the two major facilities which have to be established on case to case basis, which demand an investment of the order of 1500+ Crores. These facilities are expected to be established under the proposed AERO ENGINE COMPLEX by MoD as National Test Facilities.

We need to establish these test facilities for engine development.
  • Twin test cell at GTRE
  • High altitude test bench
  • Flying testbed
There is no update on the twin test cell facility after an EOI five years ago.

You can get a used 747-8 at cheap rates for a flying testbed.

DRDO actually already acquired 100 acres of land at Telangana for High altitude test facility.

More on planned GTRE Rajanukunte test facility from 2016:

GTRE has planned to set up Full Engine Test Facilities for Aero Gas Turbine Engines and Component Test Facilities at Rajanakunte Campus, Bengaluru.

The following Component Test Facilities to test Gas Turbine Engines have been envisaged at Rajanukunte, Bengaluru.
  • Fan and Compressor test facility, combustor, Turbine and Afterburner test facility with thrust Vectoring Nozzle.
  • Twin test cells for full scale engine testing along with Engine Assembly Hangar and Compressed air House.
  • Small Engine Test Facility.
  • Test facility to test Marine Gas Turbine Engines.
  • Air supply facilities for test rigs, buildings, roads and other infrastructure has also been planned.
The above test facilities are likely to cost approximately Rs.2100 Crore.

There are no used 747-8s available as of now and it is the newest and most expensive variant of the 747 family, I think you are confused with the 747-400….anyway IMO the last 747-400s left with Air India should be converted for the purpose of flying test bed like the former air India a319 “ Anusandhan” for testing sensors and avionics of the AMCA program.

Yes, I meant 747-400. There are so many available in the open market. Doesn't have to be AI.
