Re: Indian Military Helicopters

The Ka-226 is another one of the geopolitical buys from Russia in the same way that the Apache is from the USA. I wonder if the armed forces also push for these sales as a way of applying pressure on homegrown projects to speed up their programs or lose out. Can't blame them if that is the motive. I...

Re: Indian Naval Aviation

I admire how the posters on this thread are discussing the navy's needs in defeating the upcoming Chinese carriers using P-8I, UAVs, anti-ship missiles etc. In other words: countermeasures. And to pay for these countermeasures, we are willing to give up our own carriers. However, remember that the I...

Re: Indian Military Helicopters

I also hope that they qualify the LCH to fire the Hellfire missiles being procured in bulk for the Apaches. We should never be in a situation where the LCH has run out of stores for its ATGMs up in the mountains, but a pile of Hellfires is sitting around in warehouses for parked Apaches that cannot ...

Re: Indian Military Helicopters

Its not just the aerodynamic shaping that is the issue. It matters if they changed that circular pole underneath that aerodynamic fairing. If not, then that shaping would not benefit the structural limits. On the other hand, if they removed the circular pole altogether, and replaced it with, say, a...

Re: Indian Military Helicopters

Will a heavier payload if the spar can accommodate extra ordnance impose significant penalties with respect to the helo's performance? Range, speed, endurance, etc.? Perhaps why the "L" is in the name. Yes. An LCH carrying 16 ATGMs is not going to be flying nearly as high in the mountains...

LCH boom went through iterations. Initially it was designed to maximize stealth. The drag was found to be too high. So, they went to an aerofoil design to reduce drag.
