Supersonic flight is still up in the air,..... for now.
It wont be very practical until scramjet engine technology has matured and even then the conflict of very low drag but high internal volume for cargo or strategic weapons for the transport or bomber version will make the design either very very expensive... which is hardly justified, or not very practical... ie a hypersonic bomber able to carry one 500kg bomb at hypersonic speed for 2,000km, or a cargo plane able to carry one jeep at hypersonic speed for 1,000km... and both aircraft being very very expensive.
But until prototypes of the plane are built and begin flying, there is no telling how well the plane will actually perform or if it is even practical.
Yeah... what would Russia know about aircraft design?
I would say a hypersonic transport plane would not be practical, but at least they haven't claimed it will be stealthy and able to supercruise...
What do they expect for 5th gen FFS, anyway now that the Rafale is out they'll have plenty of cash.
They were going to spend 174 million dollars per Rafale... 22 billion on a 10 billion contract... they could have had 10 aircraft carriers with complete MiG-29K air wings for that but the critics who lambasted the carrier deal seem to be suddenly quiet...
4) its stealth features badly engineered.
In what way the stealth is badly engineered is not mentioned anywhere in the article, sound like BS ironically from BS.
I have seen pictures of the first YF-22 and it didn't look so stealthy either... I think the time to criticise is when we see the serial aircraft design...
5)India's share to low.
In what way??
Increasing share is easy... pay more money...
The article brings up some interesting question, how many runways in Russia are capable of handling this bird, the fuel load thing is obvious BS considering it only has one Turbine engine.
They mention three related designs... I suspect the single engine model is the 80 ton payload version with the 150 odd ton model perhaps with 3 or 4 engines and the 250 ton payload model 5-6 engines perhaps with an engine driven blown flaps system aiding lift at takeoff and landing... perhaps reducing the engine requirement... I would normally expect the 80 ton aircraft to be at least a twin engined aircraft and the middle with 4 and the biggest with 6 which would work with the AN-124 design where a reduced scale model with two engines in the 80 ton class could be imagined.
If the assisted fan system can reduce the number of engines required making it a single 80, twin 150, and a four engined 250 ton aircraft would make them cheaper to build and operate assuming rather huge powerful engines, but then the engine for the PAK-DA is based on the 25 ton thrust turbojet, so assuming a lot of bypass air you could increase thrust 4-5 fold with a lower velocity so lots of thrust but no supersonic speed option as it becomes a turbofan.
Would be interesting seeing a transport put on afterburners to take off, but most of the flight it doesn't use full thrust anyway so they would be rather more fuel efficient for most of the flight except takeoff....
Ilyushin, that's great, Tupolev got the PAK-DA if Ilyushin gets the PAK-TA it would be great.
Would be interesting if they cooperated on basic design and propulsion...
Hmmm... sources vary, but seems legit around 135 tons for vanilla C-5 close enough and 142 tons for C-5M.
Bollocks... Vanilla C-5s manage 105 tons when they are operational.... it is not an accident that the An-124s are busy doing NATO business around the world...
Admit it, you just wrote that post for a chance to say An-22 Cock.
Come on TR-1 that sounds like cock envy....
The vid talks about electric fans and gas turbines. It seems there's a battery on board too.
Nahh... batteries are too heavy... it is most likely the electric fans would be driven from an alternater taking power directly from the jet engine/s.
We've seen supersonic and biggish size before - Tu 160.
Except the Tu-160 is only supersonic with its wings swept right back... I rather doubt this transport will have heavy variable sweep wings... which means a moderate sweep as shown in the vid to get airborne with a decent load which would be too high a drag to allow supersonic flight.
I know Russia spoke with Boeing about a supersonic 747 sized jet in the early 1990s. But adding stealth and perhaps range is a whole new issue.
With the Tu-160 and Tu-144M the Russians have rather more operational experience with large fast aircraft than anyone else... yes... even concorde.
I'm a little puzzled at the idea the Pak Da is sub sonic now, but the cargo plane... we believe is actually supersonic. Normally, the 2 are the opposite way round.
If they are both basically flying wings they will both be subsonic... which will make them cheaper and simpler.
Finally, I wonder how much drag the shape would have. And how much stealth. Unlike the B2, it has a tail. And its body, whilst blended is a fair bit wider, and slightly taller.
Have another look at the B-2 is it very fat from side on, but the tail will greatly reduce stealth it will improve control... especially with the largest model carrying 250 ton payloads that will likely include external loads like the huge fuel tanks for super rockets/space planes...
Perhaps it could mean higher quality equipment, but being flexible and able to shuttle it from the Kurils, to the Arctic and even off to Africa at lightening speed.
I rather suspect armata will be used in defensive conflicts rather than invasions so the bid to make them air mobile is based on getting the capability to move an armata brigade from one side of Russia to the other in a few hours instead of days or weeks by train.
I also think the problem of replacing ukrainian antonov based transports is key and if they can kill several birds with one stone and create commonality between the different types and jobs all the better. Right now there is only one An-225 which was designed and built for the purpose of moving oversized payloads for the Soviet space industry... Ukraine now owns the An-225 and has no space industry to speak of, so the issue of replacing the An-225, An-124, An-22, An-70, An-12, An-140, and An-72 and An-26, An-24, and An-32 having a unified design replace the top three simplifies things immensely...
This new 250 ton aircraft would replace the An-225, the 150 ton model replaces the An-124, the 80 ton model replaces the An-22 and the incomplete Il-106, the Il-476 replaces the An-70, the MTA with India replaces the An-12, the Il-112 and the Il-112V and perhaps another model with more engine power replaces the An-24/26/32/72/140.
Yes. Yes I did.
You sound very cock sure...
Several have noticed what is a large plane apparently powered by just one engine. And therefore suspect that it would be a subsonic jet.
A flying wing is very low drag but needs a tail to be supersonic because of the cg shift at transonic speeds. I think this design is subsonic based on the wing sweep angle.
