Wonder why they didn't put the drag reduction coverings of the TD2 at the gun and front gears?

Just what I was thinking, perhaps they discovered the added weight wasn't worth the potential drag reduction?

Surely that fairing didnt add that much weight.

Perhaps not but even if it was featherlight, if it wasn't worth having on the bird then it makes sense to take it off, no point in having any extra KG onboard if it isn't actually adding performance to the machine.

Perhaps such fairings will be on the production model, who knows but I haven't seen it on any other operational attack helo and that part is a bit telling. It looked very nice and fair enough on HAL for trying some unusual ideas but if it isn't worth it then it isn't worth it.

it might b affecting the maneuverability of the gun........like hampering the horizontal angle......
what do u say @Abingdonboy @Water Car Engineer
or just that they havnt assembled it yet

Z10 and Tiger has a frame over the gun.

i have 2 questions for the experts here:

a) why is the camera on the topside.? hw will it take pictures of the ground/

b) The missiles on the wings of the copter is inclined at angle and not straight. in other attack helicopters(z10, apache..) wings r perpendicular. is it a design flaw?

The same reason your eyes are above your mouth and your Nose. Do you have problems seeing the ground ?

b) The missiles on the wings of the copter is inclined at angle and not straight. in other attack helicopters(z10, apache..) wings r perpendicular. is it a design flaw?

How is it a design flaw ? what is the optimal design ? what is your criteria for design ?

Wow what an analogy..if i have to see the ground right below my head..i will turn my head towards the ground....so if the helicopter has to see the ground right below..what should the helicopter do? do a 360 deg flip...?

Not a fan of this camo, should have gone with the the "Tellis grey" i.e. the standard IAF grey.

Anyway this is just what HAL is painting them, it will be up to the respective services what camps they have.

You mean Tipnis grey?

+ @sancho
I think the fairing is not ready

@Supply&Demand
Think rotor downwash, this is a better option, see mi24 mi35 etc, even tiger has bent stub wings not horizontal

If you want to see the ground BELOW you head i.e. the ground Below your feet, bending your head forward will not help ......... you need to move your feet.

Same principle with the Heli too.

But if an enemy is right below then its probably too late to look down.

I see it as @Water Car Engineer, the weight of the gun fairing as well of those at the gear hardly makes a difference and when you see how many changes they made to the airframe from TD1 to TD3, just to reduce drag, it would be surprising if these things won't be added. Lets see about that.
