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

Thankyou Sir........

Simpler engines mean greater reliability, better resistance to battle damage, easier maintenance, and several other advantages including lower cost, though cost is not as dominant as it is in the civil sector.The technology of gas-turbine engines has never shown the slightest sign of approaching a plateau, far less a barrier. Since the dawn of gas-turbine aviation in 1940, the power available from a given bulk of engine has doubled roughly every 30 years, while specific fuel consumption rate of fuel consumption for a given power output has consistently fallen below the most sanguine expectations. We also did our tests the National Aerospace Laboratory (NAL) has apparently tested a scaled-down (how scaled down is unclear) Rustom-1 airframe with an indigenously developed valved pulse jet engines.

This picture was taken during the flight test which possibly happened early this year, or perhaps late 2010, but provides a sense of the things NAL is trying out. The agency is also involved with the Rustom-H MALE UAV and the AURA stealth UCAV programme, in the areas of design, materials and propulsion.

i am looking forward to see the current engine mounted on the test UAV and looking forward for the results

What was HAL doing for 30 years really.

They were masturbating and still nothing has come out yet!!

What was HAL doing for 30 years really.

Their Engine Design Bureau made a few piston engines and a turbojet engine in the 70s,but it was closed in 80s (or renamed ?)

Check Comment #19 .... Then continue here.. Very interesting What do you guys think about it ? More speculations. As this 25KN engine don't exactly fit with what we are working on. Another (small) chance that US is willing to share UCAV technology with India This might be hush hush . But check this out. ..

W570 UAV - HALE .... With two 25 KN engines ....

More clarity ? Check this out .... We well be making a Beast with new 25 KN engines ....

Powerd by two 25KN engine .This flying-wing-concept vehicle has a 50m wingspan and a gross take-off weight of between 11,700kg and 13,800kg. It would be able to loiter at 80,000ft (24,400m), with up to 42h on station, fielding an unrefuelled range of 34,600km (18,700nm) and a total mission duration of 60h. The W570 would carry payloads of 4,540kg and heavier."
...
"If funding becomes available, Loral proposes that 24 General Electric engines, built in the 1980s for high-altitude UAVs and now in wind tunnel testing at NASA Ames, could be pressed into service as interim power plants."

Without quoting the whole abstract, Loral was pitching W570 around for the role we now know as Sensorcraft - and they were pitching it with the same engines Cook's sources mentioned.

I can't for the life of me recall who owns that Loral unit now, but maybe PHAE, if it exists, is actually W570. Maybe Loral found someone receptive to their pitches in the late 90s.
(It may be worthy of note that while Polecat and W570 are very similar, they appear to have very different family trees)

Good move and it will finish product fast with minimum risk

Loitering at 80,000 ft - that's higher than a U-2's ceiling! So how about its cameras? Resolution? And it can't be a UCAV as seeing its enormous wingspan it cannot follow a Hi-Lo-Hi flight profile as it could be easily detected and shot out of the sky.

I think for UVAs and Missiles.

UAVs - Yes.Missiles - too powerful for that!!
