As seen above no recoil is seen on the hind what so EVER!

Unguided rockets should have no recoil what so ever. Correct me if I'm wrong,ask an attack helicopter pilot who have fired unguided rockets...

Unguided rockets are very similar to recoil-less weapons, meaning the thrust after ignition is all dissipated behind the rocket to the open air! Where is the strong recoil going to come from?
Thanks
You clearly have not fired a "recoilless rifle" ;-)
And I give you an tip... IT RECOIL.

IT ain't as much as if tube would be closed, but it still kicks.

We will take a look to see if anything is not working.

Thanks
Okay, then logically a AH-64 would as well have one, considering how advanced it is.

Depends where the rocket sits, and so there the thrust is, relative to the COG.
There will be a point that if you push there, the aircraft will simply move back, not pitch up or down.
Push below that and the aircraft will pitch down, above and it will pitch up.

Edit: Ah, apologies I missed that you mentioned pretty much the same above.


One consideration though is the size, weight & stability of the launching platform relative to the size & power of the rocket. Ground based systems have very large rockets compared to the launching platform where as attack helicopters are launching quite small rockets compared to the size and stability of a helicopter.
Perhaps, but helicopters are entirely without ground bracing and free to move under the influence of the back-thrust. You could move one like you could move a boat, except air is less viscous & so it would be eaisier (& you can move quite a big boat by hand).

Just to be sure are you setting your rockets up correctly for the compensation of recoil?

Damn BigNewy,

when did I get the Ka-50..back in 2012...and I never knew about that dial. Explains a lot of what I experienced.

I tell everybody to RTFM...and skipped it myself.

Shame shame shame on ME.

I think I selected the wrong program #2. in the manual it only speaks about the ballistics impact point not the recoil I'll do more testing and see if it ever accrue again under the right program.

Very smart comparing MLRS with rockets that weigh more and are larger to the rockets of the helicopter that are less than 1 percent of the size and weight!!! Well done.

The amount of recoil man! watch above. And enjoy. It's okay.

How about RPG7... Yeah it kicks but can't call that a recoil.

Not a big deal.

Not apples with apples though, Mi-25 & S-5's..
&
1/ doesn't matter how big the rocket it, it's how much surface area the exhaust gasses have to work on.
2/ Your video doesn't show a Ka-50, it shows Mi-24 with the rockets mounted in a completely different configuration.

I tried to explain why that made a difference before.
There's a competition shooting discipline that involves rapid firing 3 groups from a pistol from a standing position at 25m with one hand. 5 shots in 8, then 6, then 4 seconds.

They're only .22s, so the recoil's not great, but it's enough with a normal configuration (high barrel) to mean you have to aim again.
The Russians built the MTs3-1 Rekord with the barrel in line with the shooter's arm, so no flip-up on firing. Same amount of recoil, but a different alignment eliminated the tendency of the barrel to rise (actually it probably kicked 'down').

Watch this video slowly. At 4:00 an AH-1 fires a rocket from the left station and the aircraft is kicked into a yaw by the rocket launch.

or watch the kick on the launcher here from 0:59
