Sikorsky S-97 Raider

It will certainly help toward aircraft maneuverablity, but I have to wonder about the aural signature of putting a C-130J sized propeller into beta at speed.

One has to think they did it on the Cheyenne.
 
There is likely data out there somewhere on AH-56 signatures. My curiosity is as to how much aural signature is generated when you shift the prop into beta (reverse thrust). It came to be listening to a C-130J doing a short field landing demonstration. There was a very noticeable signature from the props when they did so. Sikorsky is pitching that it is a quiet helicopter so I am wondering, how far out do you have to turn off the prop to make it quiet(er)?
 
Spot the difference

There's some changes to the shape of the fairings in front of, and between, the rotors . . .

cheers,
Robin.

And the canopy reshaped.
One is green, one is black. Just wanted to get that out of the way.
 
Has Sikorsky ever discussed why they went with side-by-side seating for the S-97 Raider/FARA instead of tandem seats? Something similar to the FVL attack helicopter they've shown some CGI of seems like it might have made a better scout helicopter. On the plus side if their FARA offering can carry some guys in back it would be ideal for SF types or ferrying around other small specialist teams.

This week at Quad-A, Sikorsky pushing Raider X for FARA re the Indo-Pacific region

Sikorsky X2 Technology Propels Army Readiness in the Indo-Pacific

The U.S. Indo-Pacific Command (USINDOPACOM) covers more of the globe than any Department of Defense geographic combatant commands, making it vital for the military to operate at range.

"RAIDER X is custom-built for Indo-Pacific missions." I hope not! Lots of other places it might be needed.

" FARA will act as a networked sensor, a “quarterback” for managing the effects and communications " Same sales pitch as Comanche.

Oh well.
 
Okay, related sidebar question. What would happen if you had a rear prop like the X2, except you offset it to point diagonally forward and only have a single main rotor? Maybe you even make the rear prop adjustable in direction too.
 
Kinda be like this:

Except the propeller would be going the other way.

Karem proposed exactly that for FARA. The AR-40...

That actually looks more efficient.

PS: Just when you think you've come up with a great and novel idea but someone(s) else got there first. :D

It's a pity that this concept wasn't developed further. I would love to see a modern day technology demonstrator.
Some more info on Sikorsky's Rotoprop here:

It will be interesting to see what comes out of the AUSA show. Both Sikorsky and Bell have surely mobilized a battalions worth of retired Colonels to wax elegant on the virtues of their products and underhandedly disperage the competition.
