Re: LCH and other Helicopters Discussion Thread

oh please, not a naming discussion again. use the mil misc thread if you absolutely can't do without it. Yeah, we followed your 'naming' discussion quite closely actually! Even we have been tying ourselves up in quite a few knots on that one! At the risk of getting some brickbats thrown on me for r...

Re: LCH and other Helicopters Discussion Thread

@ Question have crept up relating to the HAL's latest blunders suggesting that Turbomeca has been arm-twisting Hal because of latter's inability to develop the Transmission in-house using a single Shakti engine. Can you please elaborate and clear the hot air around this?? Is a modified version of S...

Re: LCH and other Helicopters Discussion Thread

the mast mount thing probably came about from the need to hide behind forested ridges in korea and europe and just peek up with the radar...and creep around below the tree canopy level. You are right on that one - and yes I agree the mast mounted sight looks more mean & predatory! But try and c...

Re: LCH and other Helicopters Discussion Thread

........... 2.We need to get the basic platform perfectly optimised for the contradictory low and high altitude requirements - that, in my opinion is the primary challenge. ............. Can you please educate us more regarding the contradictory requirements for high and low altitude? My little und...

Re: LCH and other Helicopters Discussion Thread

Please also consider discussing Design Parameters and Considerations for its aerodynamic performance. I hope I am not being over demanding. That's a very general Q - any specific line-of-thought? 1. Is the LCH equipped for network-warfare roles just like Apache? 2. What do you think are the major h...

Re: LCH and other Helicopters Discussion Thread

@Surya, - Thanks! @Gaur “When the first model of lch was shown, some people questioned as to why was the sensor pod placed above the nose and not under it like other attack helicopters. They said that this would greatly decrease the fov. Others, on the other hand, counter argued that if the target w...

Re: LCH and other Helicopters Discussion Thread

Looks like the LCH will be optimized for high altitude and fly where others cannot fly. But that would probably explain why the IAF is looking for dedicated attack helos in the plains which will not be used at high altitude. I am guessing that this is where the competition between the Apache and Ka...

Re: LCH and other Helicopters Discussion Thread

Excellent ...excellent......Thanks Hari Sir...How many prototypes of LCH has HAL developed so far ? Also are we roping in International partners for testing guidance/direction or will it be a sole HAL effort with inputs gained from ALH program? And as rakall pointed out ..any updates on the weight ...

Also please do tell us about LCH...hows your feeling...hows the handling...anything and everything would be highly appreciated..... :D Well, the tandem seat and tail-wheel layout appears to be the right way to go for the dedicated role LCH. We put the pilot in front and the co-pilot-Weapon System O...

Re: LCH and other Helicopters Discussion Thread

There has been a lot of speculation about whether the design of the LCH is going to be modified later on or not. As in whether the outer mould line is frozen or not and whether or not it will be further streamlined. Regarding the LCH's canopy, it offers more visibility and less protection to the pi...

Also please do tell us about LCH...hows your feeling...hows the handling...anything and everything would be highly appreciated..... :D Well, the LCH shares the same rotors of the ALH, however has a different fuselage and certain other different systems.

Re: LCH discussion

Would you know what are the two-stages? Also how do we calculate the percentage of survivability. Are there cases of how the helicopter can crash land and with this tolerance we can overcome 85% of those cases? Of the 15% of the rest of cases may be coming down on its side, top, tail, etc. Can a he...

Re: LCH and other Helicopters Discussion Thread

@ Craig Alpert -Re -The ceiling of the ALH Actually its cleared to 6400 m for the older TM-2222B2 engine (although at a lower weight) and its now cleared to 6500 m for the new Shakti engine version at a fairly high All-Up-Weight I'm not sure how CAG got its figure of 5000 m - the 6400 m ceiling is c...

Re: LCH discussion

I hope so but i think i get the theory behind the mounting now, its deliberately kept independent from the cockpit frame because any serious landing would not stress the structure and instead the mounting will either bend or crumble hence absorbing the shock without harming the frame and can be rep...

@Prastor -"If only we master engine design and manufacturing now" That's easier said than done - its a devilishly difficult thing to attempt - almost a black art if you look at today's state-of-art high performance turboshafts such as the Shakti with its software-control! The power-to-weig...

Re: LCH and other Helicopters Discussion Thread

The CAG is definitely NOT a bunch of hare-brained babus as has been made out to be. I have found some of their remarks and analyses on certain aircraft acquisitions surprisingly precise and accurate. Don’t underestimate them, they are good. However, in the case of the ALH (Dhruv), I do believe their...
