    What's wrong with the 3 engines? Electric cars now also have 3 engines and they rock

    In addition to what others said it eats up valuable internal space which is huge problem with stealth airplane which has to carry weapons internally

    Also less space for fuel (which third engine burns additionally)

    There are small penalties in efficiency, space and maint. But you do get a thiner profile and redundancy, also since you have to only contend for climb out with one engine failure, you need less maximum thrust for safety and that prob neutralizes most of the negatives other then maint.

    I think this picture describes every user here and on other forums of China claiming it has a 6th generation aircraft.
    CAC‘s 6th generation fighter prototype/demonstrator - Page 3 17354110

    Claims of Quantum radars and laser sensing satellites detecting submarines killed the hype of their own 6th gen aircraft. They have not offered outside of the box thinking in any aviation achievements from patents, avionics and missile breakthroughs, engine breakthrough performances, etc.

    Engines: China has no dates on estimated production or development for adaptive cycle engines or detonation engines. Usually, the performance of engines determines what kind of aerodynamic layout you would have planned for a new aircraft. Using foreign engines on your 5th generation aircrafts not too long ago to immediately designing what the physical layout would look like for a new generation aircraft just seems too early and set for compromises in combat in case actual 6th gen aircraft engines come out that would make you question if you should have done a different physical layout than the one you did before with underperforming engines.

    Patents: US did serpentine ducts, flat nozzle, round serrated nozzle designs. Russia did partial S-ducts with radar blockers for performance, switching from round nozzles to serrated round nozzle, to round flat nozzles, removed horizontal stabilizers on the Su-75 and made the aircraft configurable to be one seat, two seat, or AI by changing cockpits. What did China even do that showed some kind of creativity in aviation that made them look different or standout?

    Electronics: Of course, they have come a long way to producing smaller wafers with high yield production overcoming western sanctions. However, the U.S. will still have the edge in radars because of using Taiwan or Japan's electronics production for their own 6th gen aircrafts. And Russia started production a month ago in PICs and have their own photonic computer set to be made to operate in Zettaflops which will match Intel and Japan's supercomputer plan's for the same Zettaflop range in like 2030 which is insane because Russia's domestic electronic wafer production capabilities are at 300nm to 90nm when they made those claims and eventually they will get to smaller size production capabilities to 11nm to improve their PICs https://www.notebookcheck.net/Russi...stem-to-rival-ASML-s-technology.935627.0.html.
    Even Intel is changing its direction to photonics and a lot of investors in the US are looking into this direction as well. PICs also enhance neural network and A.I. capabilities. I am pretty damn sure China's 6th gen aircraft AFAIK is not flying around with PICs and a photonic computer.

    Missiles: RVV-MD2 is basically the same as AIM-9x Block 3 with the 50-60km short missile range and 360-degree LOAL engagement. Both US and Russa are designing internal 300km air to air missiles and internal hypersonic air to ground missiles. Anything like that from China has been announced? I think ramjet air to air missile designs will be the future for same high speeds but longer ranges and 2030+ we will see production of these kinds of missiles for any 6th gen aircraft.

    What makes any news from China feel so disinteresting like 6th gen aircrafts is that it feels like a copy and paste from another country's kind of aviation achievements such as the US. The UK and China immediately trying to field 6th gens while the US and Russia are taking their sweet ass time tells me whose latest aircraft designs would have more defining features what makes a 6th gen aircraft a 6th gen aircraft. This doesn't mean I will completely go shit on the Tempest and J-36 but that my current expectations are set very low unless they go with upgrades later on them.

    China has mastered the lighter and simpler DSI air intakes, the fact that it's using splitter plates, indicates this fighter will fly at a wide range of speeds.

    Oh God. This guy is copy/pasting the Drive level nonsense.

    How the hell can this thing fly "very very fast""very very high"?
    China doesn't have ALIEN technology.

    It won't fly very very high or fast with DSI intakes.

    Are we sure this isn't the JH bomber ?  The J-20 is a monster and it looks big compared to the J-20. Seems too big to be a fighter and too small for a bomber. Maybe it is a scaled down prototype of the JH

    It won't fly very very high or fast with DSI intakes.

    Assuming the third engine is a cruise ramjet engine then the two air intakes for the two turbojet or turbofan engines would not be used at high speed or high altitude, the air intake on the top that feeds the ramjet would be used for high speed high altitude flight.

    Does that look to you like a airframe optimized aerodynamically for Mach 3 ? Heck never mind that even upper Mach 2 one ? Or ability's to handle the heat of those speeds ?

    No high G super maneuverability either. It's optimized for long range stealth missions.

    Indeed, something like the Ochotnik B as ALAMO wrote, only heavier and manned/with an unmanned option. China is moving forward quickly, making more and more airframes. It should also be remembered that the much smaller Russia is preparing a new stealth bomber PAK DA, a new light fighter Su-75, a heavy drone Ochotnik B and a fighter interceptor PAK DP. And the resumption of production of the heavy bomber Tu-160M.

    Unmanned versions of both the Su-57 and 75 are also in the making. These will be fully multi-role machines equal in all aspects to their manned versions.

    Is this the same thing or something else? Shocked



    For China, 2024 is not over yet! 🇨🇳
    🔹 Today, a new unidentified aircraft spotted in the China, some sources attributed the aircraft to the spacecraft project of the China State Aerospace Science & Technology Corporation (CASC), Tengyun. The project's goal is at 2030.
    🔹 The project includes a hypersonic carrier with a recoverable spacecraft. the carrier transports the spacecraft to the edge of the atmosphere, and spacecraft returns to Earth after completing the mission.

    Another dose of nonsense. About how China has a hypersonic plane. They don't have hypersonic missiles yet, but they do have a plane that will carry cargo into orbit. An ever greater departure. What is in the film does not fly at high speed. Nothing extraordinary. China doesn't have that much experience with hypersonics yet. It's doubtful they'll have scramjet engines for the plane.

    I really don't think they would fly at hypersonic speeds over built up areas - and it obviously does not fly at hypersonic speed all the time.
    This is just a demo flight - or more likely a first test flight. China is one of very few nations that has mastered hypersonic tech.

    Seriously you should open your eyes. China is RAPIDLY expanding it's military might leaving everybody else behind.

    They don't have hypersonic missiles, let alone an airplane. They have missiles similar to hypersonics flying 5M. What Russia has had for 50 years.
    They probably don't have a scram jet engine. I am full of admiration for China's progress and they are huge. This does not change the fact that in hypersonics they are far behind Russia.Such flights require a revolution in materials, etc., not just the engines themselves.

    Meet the WZ-8 hypersonic recce drone reaching speeds of Mach-6-7. It entered service in 2019.

    CAC‘s 6th generation fighter prototype/demonstrator - Page 3 Wz-8_a10

    A much newer hypersonic drone is the MD-19. They also have a Khinzal equivalent that may very well be hypersonic.

    Another one is this thingy underneath the H-16 that is claimed to be hypersonic
    CAC‘s 6th generation fighter prototype/demonstrator - Page 3 H-6n-m10

    They also have hypersonic glide vehicles.

    'm talking about the equivalent of the 3M22. A hypersonic air-breathing missile powered by a scramjet engine. Not an aeroballistic missile powered by a solid-fuel rocket engine. A scramjet jet could possibly power some hypersonic aircraft. It is also unknown whether they have full-fledged HGV technology.

    It's a rocket plane. So not likely it can sustain those speeds for long duration if it indeed does that speed bar descending trajectory(And even then i doubt it)

    According to the developers the drone’s primary use won’t be against Taiwan but instead US military bases in the Pacific. Also not just the USA, but "All Southeast Asia has to worry about it" they say.
    That implies that it should have significant range.

    Exactly my point.  To have that range it wouldn't be possible rocket powered plane to do at mach 6 or 7 of that size ...continuously.  So either  it doesn't remotely fly that fast or possibly it gets up to that speed on a descending trajectory.
