Sikorsky S-71 (AAH contender)

[overscan (PaulMM)]

S-71 - Proposal for AAH (won by Hughes AH-64) based upon S-70 (UH-60 Blackhawk) rotor system. Not built.

It used the S-70 rotor system (AAH used the same engines already) and an S-67 inspired fuselage.

You are right, the cockpit was skewed, to give the wepons operator a good viewfield and use at the maximum the Boeing's UTTAS proposal structure, And, out of completeness, a daring of the S-71 is here http://www.secretprojects.co.uk/forum/index.php?topic=655.msg5145#msg5145, just in case... If someone doesn't beat me at this, this night I'll post the CL-1700 and maybe the Boeing's front view

Nice work with the drawing of the Sikorsky S-71

I have heard of it many a time, but never seen its layout

Thanks Overscan!

Rare photos of the S-71 model according to the AAH program http://www.sikorskyarchives.com/S-71%20AAH.php

Nice pics. Sikorsky have done a website pretty close in concept to one I've been working on... But theirs is full of missing stuff and has a few typos... I hope they can get decent historians to sort the mess out.

who knows why two models have one name S-71

 

[Stargazer]

I only know the mock-up in the first picture, but it seems to me that they were probably both related to the same program at different stages. The second one looks a little earlier and more crude to me, but still an advanced Army attack helo.

Yes, the top image is the final configuration, the bottom one is an earlier version. Final has altered IR suppressors on engine exhausts and modified wing/undercarriage.

Ammo?

what is behind the turret gun

Ammo?

That would be my guess as well.

 

[overscan (PaulMM)]

I'm pretty sure thats an S-67 Blackhawk. S-71 had a simiar shape.

 

[yasotay]

It is the S-67, original Blackhawk.
