So I did a bit of digging about Aerosila they named as supplier of new Tu-95 props
Turns out they're the continuation of the main Soviet propeller developer/manufacturer since i-15 in the late '30s including the props for Tu-95, An-70 & Il-112/114. (as well as various other related products)
Mostly seems to have been working on APUs recently though
But apparently are equipped with modern digital design/manufacturing gear & those Il-112/114 props do give some recent experience.
Interestingly the Technical page for SV-27 (raked scythe blades for An-70, btw its 8 blades front, 6 blades rear)
says its designed for 11,000hp, but the History page says 'later' 14,000hp.
Still short of the quoted 15,000hp for new Tu-95 engine but pretty close so it may indeed be the case that the new prop is a variant of the An-70 prop
