By SP's Special Correspondent

March 07, 2015: HAL's ambitions of entering the aircraft engine space in a meaningful manner have become clear now. While the development of high performance combat aircraft engines are being left to the DRDO's GTRE and its international partners, HAL has unveiled the HTFE-25 (Hindustan Turbofan Engine 25) that will be pitched to power trainer aircraft and business jets in the twin engine configuration. The 25 kN turbofan engine, slim in design, is 1,730mm long, 590mm in diameter and weighs 350 kg. The HTFE-25 is a low bypass twin spool mixed flow turbofan engine with wide chord fan blades, sports a high efficiency compressor and advanced combustor. The engine is controlled by full authority digital engine control (FADEC). The medium thrust engine could be pitched also for unmanned air systems of the future. The HTFE-25 is being developed as a fully in-house effort funded through internal accruals. HAL projects that the engine could be ready for operational service by 2018. The company has already begin testing waters abroad and in India for possible utilisation of the 25 kN engine, including with private players looking to build aircraft in the country.

Nice.

 

[Ind4Ever]

Is it the one made out of 3D printer technology ? Which HAL showcased during Aero India 15 ?

 

[That Guy]

Knowing HAL, expect delays, lots of delays...and cost overruns. Good luck, my Indian friends. Do try not to be too hard on them.

You can have your cup of tea.....

HALs delays was attributed to Congress raj of no political will to make in India...

Just start counting ingress of OUR defence manufacturing, counting has begun.

 

[Skull and Bones]

Now fit that into NAL Saras.

 

[CONNAN]

this is the same engine discussed in below thread

HAL shows off 25-kN engine but doesn’t disclose its application

 

[SQ8]

Perhaps they should have stared with this instead of the Kaveri.

This 25 KN engine is more than enough for saras like plane and AURA like drone. This shall be more than enough for sitara like plane. So all in all a very good development.

Yes actually, but only with a bit more info.

 

[GR!FF!N]

a product of Kaveri project..

 

[AMCA]

Kaveri is not the product of HAL but GTRE. HAL has its own Engine R&D facility

 

[sudhir007]

i dnt understand why HAL going for this when they already deal with NPO saturn for AL-55i and they are already paid for it

 

[HariPrasad]

This is a gradual way to boost our capability. Next should be the 50 Kn Engine of AURA fo;;owed by 120 KN engine for LCA MK3 and Aura.

The Pratt & Whitney PW545B on board the General Atomics Avenger gives a thrust of 3991lbf or around 17.75kN.

Dimension wise the Pratt & Whitney PW545B is,
Diameter 32 ''
Length 68 ''.

P&WC: PW545B

Whereas the HTFE-25 (if the info on the brochure is to be believed) gives a thrust of 25kN or 5620lbf and is 1,730mm long and 590mm in diameter.
Diameter 23.23''
Length 68.11 ''.

I couldn't find both the engines' t/w ratio but at a glance the HTFE-25s t/w ratio maybe is better. Or am I wrong?

If HAL can finish it in time, it could be applied in different projects particularly UCAVs.
