HAL LCH| Updates and Discussions

Check the picture of the mock up that I posted in the stub wing post, that might give some hints about the position.

I just noticed that

I certainly hope the placement of the sensors is how they are shown on the mockup, it would be such a shame to see those sensor blocks on the Rudra/ALH on the LCH, if they could be built into the airframe that would be great.

Wrt the exhaust, just checked some pics of the Apache:

Early version

Modified for IR reduction, upwards and fully covered

Sir, the more I look/think about it the more I'm sure it is about reducing the IR signature, in fact that new intake @Water Car Engineer points out seems to prove this further- a cool air intake to reduce the thermal signature of the exhaust.


+ that modified upwards facing exhaust was never adopted.

Evolution of the LCH

TD-1

TD-2


I really hope they keep the cowling on the main gun- that looked great!

in fact that new intake a cool air intake to reduce the thermal signature of the exhaust.

Not sure about that, the new inlet then would not pass the air into the engine, but through a channel behind the new covering to the exhaust to cool it, but then you would need a now hole to let that air out again and that wouldn't even cool the exhaust fully, only from one side. But as said, they didn't even covered the whole exhaust which leaves the top end visible and uncooled.

For the Apaches? Of course, google for ah64D + iraq or afghanistan

I've never seen an operational Ah-64 with the upward facing exhausts sir.

The latest Apache standard (E):

But anyway, the progress of LCH makes the Apaches even less needed, DRDO should focus on a mast mounted radar.

The last one appears to have the standard exhaust sir. And thanks for posting the others, honestly hadn't seen that exhaust in service on any Apache to date.

@sancho, this pic was taken at HAL's ALH MRO facility, meaning that the IA/IAF are upgrading their Mk.1-3 fleet to the Mk.4 standard- very welcome news.


I'm pleasantly surprised (understatement) that the Indian military have adopted such high end tech (Full glass cockpits, FLIR, modern self-defence suite) so readily and made it their standard equipment.

Bro actually I want Apaches on our side parallel to LCH, it will give a good opportunity to look upon by HAL to modify LCH further .Also Apaches are heavy class Gunship,an ideal replacement for Mi 25 and Mi 35.

Nice images

Hoping to see SP rolling out in year or two.

Where do you propose to put them?

Rudra has one of the sensors on that very same location.

Other examples

Iraqi scout's sensor heads

Turkish T129's sensor heads on the wing tips.
