Tata already builds fuselages for Boeing.

I think the correct word is assemble no?

How exactly does a wire strike protection system work? From filmi shoots, I thought main rotor or tail rotor were the ones to get entangled first. However, WSPS seems to protect against wire strikes near windshield. How effective is this? Looks like additional instruments are needed.

yes saar, I saw that video too while searching for information.

What is interesting is the comment in the safety paper I had linked:
In addition, there were no fatalities in wire strike accidents after installing WSPS. While the reduction in the number of fatalities is due to the WSPS, it is conjectured that the reduction in the number of wire strike accidents is because the WSPS constantly alerts the pilot to possible wire strikes.


It appears that this systems helps "indirectly"

Hari Nair sir,

Do you see a potential, even if limited, naval role for the LCH? For example they could operate off amphib ships in order to support beach assault?

They don't have enough firepower to support landings.The Ru KA-52 which Egypt bought along with the two Mistrals originally meant for Russia are heavy hitters.Ideally, our planned 35K t amphibs should have either STOVL fighters like USMC Harriers and future F-35 Bs, or even our NLCAs if the deck is redesigned to allow the NLCA aboard.The ALH could be tweaked into a useful naval multi-role helo, but it would require extensive redesign.An auto folding system for rotors and tail boom essential and a surface search radar, ASW/SuW console, sonobuoys and LW ASW torpedoes.This will take time and there are already several such helos in service mainly European.

All this Dhruv auto-folding problem is confusing me - didn't HAL demo rotor and tail-boom autofolding in AI 19 ?

Slight OT, but this seems to be the best video that I found wrt to blade folding of heptrs.

Ready to go: Watch how the #CH53K’s blades fold, making it easy to transport by sea, air or land.

ET.
No takers for HAL's offer of pvt. sector building ALH Dhruvs.Reasons:
Twice the operating cost per hr. (2.1L) compared with firanv rivals.It's also thr most rxpensive in its class and a 3.5% royalty, plus a max. prod. allowed of 90 helos .With no largr market in sight too, industry views the offer as a " white elephant".
