Russia Showcases "Checkmate", An F-35 Competitor?


Recommended Posts

The Russian Federation debuted its 5th generation single engine fighter just outside of Moscow. The fighter has been dubbed "Checkmate" and was showcased in a Sukhoi pavilion. The UAC (United Aircraft Corporation) presented the airframe to the press and commented the Checkmate to be, "low visibility and high flight performance." aircraft and incorporating "a combat radius of 1,500 kilometers, the largest thrust-to-weight ratio, shortened takeoff and landing, more than seven tons of combat load, which is an absolute record for aircraft of this class."

 

Russia intends to source Checkmate to eastern nations such as India and Vietnam for starters. Of course this is a few years down the road as it's first flight is expected in 2023 and deliveries in 2026. The intention of this aircraft is to be a competitive option for those who opted out of the JSF Program for whatever reason. At least that is how it appears to me. I received this information from CNN and the source link will be posted below. Feel free to discuss Checkmate and Russia's ambitions with this new aircraft.

  They can do as they like, but if they start poking around Mars, we need a global intervention.

Yeah, they do that a lot, see: their supercarrier, nuclear powered super cavitating torpedo, infantry powered armor, etc. I never had any idea wooden mockups and scale models were so lethal on the modern battlefield!

I’m a bit confused about the record for range and payload.  When compared to the (wiki) stats for the F35 (which I assume is considered it’s key competitor), the Check has 25% longer combat radius, but a lower weapon payload.

Did I miss read something?

Correct me if I'm wrong but if it carries less tonnage shouldn't it be able to remain in the air longer?

Yes, you miss the fact this aircraft doesn't exist. It may exist in the future if everything will go as planned. 

It's performance are marketing rounded assumptions before the real engineering challenges and required compromises took their toll in the real (not mockup) plane.

The only thing i know is it's planned engine, which is hoped to be ready in 2025, will have less power than today's F-35 so it will have to be lighter than F-35 to have similar T/W ratio. When F-35 is planned to receive even more powerfull, 45,000lbf (200kN) class, adaptive cycle engine in a few years.

 

In short you can use any data you want in the advertising materials for every futuristic project, but reality is verifying every plan.

yeah...like f-35 delivered on time, on budget, on advertising materials 🙂

and now US is building something that looks like YF-23 spinn-off 🙂

  To be fair, every new generation of aircraft since the beginning ran over budget and had various teething issues, including most of the widely acclaimed ''classics''. That aside, I've said it before and I'll say it again : the STOVL F-35B was a stupid thing to do and is almost definitely responsible for the bulk of its development issues.

  Last thing I saw was some mockups/renders of a possible 6th gen hybrid ''optionally manned'' aircraft, but that's been a while.

the Russians have no imagination the design and similar to the F-35 it will surely be much faster than an F-35.
it takes Italian engineers who can give that touch of fantasy in the design and a pinch of innovation. as the engineer BARTINI did a long time ago.

I think the desire for ultimate stealth is pushing all new fighters to look similar. F35, F22, su-57, This "checkmate", the concept tempest (UK) and some Chinese ones I don't know the name of. They have differences for sure, this checkmate is more of a delta wing etc etc, but the similarity is not down to lack of aesthetic design. Its not a car...

Penso che il desiderio di furtività definitiva stia spingendo tutti i nuovi combattenti a sembrare simili. F35, F22, su-57, questo "scacco matto", il concetto tempest (UK) e alcuni cinesi di cui non conosco il nome. Hanno sicuramente delle differenze, questo scacco matto è più un'ala a delta ecc. ecc., Ma la somiglianza non è dovuta alla mancanza di design estetico. Non è una macchina...

 

 

as in FORMULA 1 that the cars all look the same, only small details change.

  Aerodynamics is a finite science = there is a ''best'' way to design your aircraft dependent on its targeted mission profile (subsonic, high alpha, etc etc). The 1950s/60s era of experimentation and ''learning'' is long over. Aircraft are looking more and more similar because all the guesswork is gone and people choose a design which is beat suited for whatever they're needing the plane to do, which is often some variation of a ''blend'' to minimise disadvantages and maximise advantages.

 

  Likewise, radar emissions are a finite science : it works a certain way that is well understood. Virtually all military aircraft, even if not stealth persay, take design cues from it because there is no good reason to make your aircraft ridiculously visible and MANY reasons to minimise its signature.

  Waste time, money, and limited weight allowance on ''being stylish'' @@ Aircraft look sleek and fast not to be ''stylish'' but because it's actively conducive to being a high performance aircraft. Their ''style'' is an incidental byproduct of their design NOT a deliberate focal point, even in one off civilian designs practical considerations come first.

In principle, I agree with the point that the maths is now known and will tend to make designs more generic.

does make me wonder how Boeing ended up with the F34 (their competitor to the Lockheed F35).

Fun fact: this "mock up" as you call it is actually the plane that will fly in 2023. So, leave mock ups to the british with their tempest as this is a real aircraft, yet yes, not fully build yet

Just an observation.

 

Going on what the mock-up displays, the intake could be relatively restrictive in maintaining airflow at AoA that could be expected in manoeuvre combat. Also the all moving V-tail has a hinge line that could cause blanking at high AoA similar to a T-tail, being blanked by airflow.

I fully understand that this isn’t really representative of a production article - many things can change - but as it is there seem to be a few design choices that aren’t really conducive to manoeuvrability. 
 

It will be interesting to see what this airframe becomes, but I think unless it undergoes a large layout change, it could be at a handicap straight off the bat.

    If it can't fly for *at least* two more years, than it is almost definitely one of the very first prototypes. The first few in any given series are usually non-flying testbeds. If it was close enough to the finished product that that SPECIFIC AIRFRAME would fly, then it wouldn't be two years away. Aircraft are like DCS modules : until it's wheels up everything is subject to change.

  Eh, there's always that one tryhard who wants to be different 😛 I think you mean the X-32, right? It's a bit odd looking from certain angles with the nose scoop which is fairly uncommon on US designs these days, but otherwise it's a pretty straightforward blended delta like most other modern presentations.

Prototypes for ground tests are being tested atm and those tests are to be finished by the end of the year

Whatever you call it, it wont become worse or better. That very plane is planned to take off and that's not my words, but what's claimed by its creator

You're free to hide in denial up until it flies

Its talked of having a longer range than Eurofighter, which to me is complete insanity, considering how relatively small it is. It doesnt look much bigger than grippen.

Well, if you study the history of the F-35 from design stage, it's hard to beat as a design Cluster FCUK.

 

Seriously, when an L.M guy ask why a vortex is attracted to a zone of lower pressure (from the strake inlet to the dorsal fin) instead of spreading outward in a leaked slide, you wonder if they haven't financed the further education of some newbies they recruited in their design team hoping they could do better.

 

Just in passing, the topic of airflow expension and compression is covered in the beginer's aerodynamics course for 16 years old who want to get a grant, so you can expect some well paid technician and aerodynamicist to be more aware, a couple of years down the road and you have the transonic and supersonic topics covered...

 

They also used CATIA from conceiptual design stage, can someone please explain to me how they couldn't get flow simulation to work with it...
