Tu-95MS "Bear"

Thats just the same pic as above of recently completed upgrade to current standard.
Prototype of the new standard is said to be due for first flight late 2019 so I think we're fairly unlikely to see it till then.
On the other hand presumably they'll need to flight-test the new engine/props on an existing airframe first so we might see that before?

As much as I'd love to see big An-70 style raked scythe blades


They seem to have gone for a relatively conservative type on new TV7-117 for Il-112


though the ones they used for flying tests has raked leading edge, flat back

I assume they will be using a counter rotating prop? If not even with 6 blades the prop radius will be HUGE. I really hope they seek to break new ground in prop fans with this engine. The incredible power of this engine is still unbeaten in the turbo prop world and I think it has HUGE potential for future airliners engines. Maybe they will go with 4 rows or maybe counterrotating 6 blade to keep the tips subsonic.

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)
http://aerosila.ru/en/products/vozdushnye-vinty-ivintoventilyatory-dlya-samoletov/vintoventilyatory-klass-tyagi-10000-kgs
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

The new propellers are called AV-60T. They are a refined version of the currently used props.

Hmm that does not sound like more then an incremental step. I was really hoping they would go with counter rotating 6 bladed schimitar fans....

Well thats much less fun
I guess my first instinct of minimal change was right.

and what is wrong with incremental steps? Su30SM is an incremental step form Su-27 too

Because as well as looking amazingly cool there is a big efficiency/noise difference between the raked scythe style props & the conventional blade style of the original props.

But new scythe are those updated ones?

perhaps at the very high speeds TU-95 reaches vs other prop planes the requirements are different

That would be russian aggression on a new level.

*Breaking news, Russian 'Bear' Downs NATO Planes*
dit dit dit da da da dit dit dit
In breaking news this hour several innocent democratic fuzzy & cute fighter jets from multiple NATO countries have disappeared off radar after being sent to intercept an aggressively Russian 'Bear' bomber sent by Putin to aggressively Russianly approach NATO borders & possibly interfere in elections along the West coast from Norway to Spain.

Military sources have been unable to determine exactly what method the Bear used to down the planes but can confirm that the aircraft disappeared from radar screens shortly after the fighters made visual contact with the Putin bomber, some form of hacking is suspected but UK Intelligence sources who cannot be identified for security reasons are unable to rule out the possibility ultra-deadly Novichok chemical warfare agent was smeared on the control sticks of the fighters before they took off 'we have no evidence whatsoever but we're quite sure that Putin ordered the GRU to do it' they advise.

While the evil communist bombers have only just started their return leg the independent definitely not a UK state sponsored info-war campaign researcher Bellingcat has released its 3rd expose on the incident with shocking proof that Putin Done It! in the form of a photo showing Skripal Novichok poisoner Russian Colonel Anatoly Chepiga at the controls of the Russian Aggressor  holding what appears to be a perfume bottle and with a Russian Built BUK missile launcher in the co-pilot seat next to him.

Coming up after the break our panel of independent ex CIA directors will rationally discuss how Putin just started WWIII, is exclusively to blame & definitely nothing to do with the weird spiral patterns on the props in the Bellingcat image which look suspiciously like '60s movie hypnotising machines...
da da da dit dit dit da da da

C'mon this dead can should return in next month. The cat will give BBC ( or big white c) an extensive interview with final proof the it was Putin himself. Red handed as every Russian is red of course.

you can really see how the TU-95 evolved from the TU-4 /b-29 though. The TU-95 is the ultimate Steampunk bomber design, it looks timeless and awesome!!!

wut? Is this a joke?    The Tu-95 is a swept wing aircraft that weighs nearly 3x the B-29 and over 50% faster....  how dafuq could the Tu-95 be an evolutionary development of the B-29 clone?  Maybe because it has two wings, 4 engines and the pilots sit at the front?....

The Tu-4 was developed first into the Tu-80 and than the Tu-85. The Tu-85 comes close to the Tu-95. So he is right that there is a line.

..the Tu-4 was superior to the B-29... it had more powerful engines that were not prone to burst into flames like the US model..

Yes, their engines were also often catching fire.
The Tu-4 is at 13:00 & the Tu-95 is at 35:15- direct descendant of the Tu-4 & is closely related to the B-29:

Ummm... No. Tu-80/85 were aborted attempts at developing the Tu-4, but the Tu-95 was an all-new deign. It may have (I'm assuming) leveraged some engineering solutions from the B-29 clone, but to all intents and purpose it was a seperate development on a clean sheet. Swept wings, turbo-props, totally different fuselage and tail shaping...

The TU-80 and 85 were developed from the TU-04 and were still piston powered. Only when a suitable engine came along, did TU-95 become possible. The swept wings were driven by aerodynamic requriements of capability provided by the engines. Of course structure, weight and payload all came hand in hand with the massive increase in power (6X) . If you cannot see the linage you are blind. There is zero chance Tupolev (as brilliant as he was) could have designed the TU-95 without having first designed the Tu-04

There is no "lineage".  Tu-80/85 proved to be a dead-end and were abandoned.  Tu-95 was a clean sheet. Just because Tupolev opted to retain some design features of the 80/85 such as the general arrangement of the forward fuselage/cockpit area doesn't mean the Tu-95 is related to the Tu-04.  It just means that the modernisations planned for the 80/85 were modified and rolled into the new aircraft.  Thats not a lineage.

The only way to settle this would be to examine structural drawings of the Tu-04/80/85 and compare them to the Tu-95.  AFAIK no such details are available, so lets agree to disagree.

BTW Tupolev didn't really "design" the Tu-04. It was a direct clone of the B-29, differing only in use of Soviet powerplant and internal equipment. Saying that he couldn't have developed the Tu-95 without first copying the B-29 is nonsense. That would be tantamount to saying that Tupolev learned his craft by copying the US article...
