    So the Bounder was a victim like so many of other aircraft of the era - engines promised that never really delivered (yes I know there was the political angle but if the aircraft had the intended engines right at the start the politics might have gone a different way).

    We may see a second chance at that:
    https://techxplore.com/news/2022-04-breakthrough-faster-than-sound-jet.html

    To simulate how combustion behaves within this volatile environment, NASA has a hypersonic CFD code called VULCAN-CFD. The code processes multidimensional flamelet tables, where each flamelet represents a one-dimensional version of a flame. The data tables hold these different snapshots of burning fuel in one massive collection, which requires a large amount of computer memory to process. In a newly published study, Argonne scientists used machine learning techniques to reduce the intensive memory requirements and computational cost associated with simulating supersonic fuel combustion.

    This new heat exchanger can help too!

    New High heat Alloy
    https://www.nasa.gov/feature/glenn/2022/nasa-s-new-material-built-to-withstand-extreme-conditions
    NASA Alloy GRX-810, an oxide dispersion strengthened (ODS) alloy, can endure temperatures over 2,000 degrees Fahrenheit, is more malleable, and can survive more than 1,000 times longer than existing state-of-the-art alloys.

    Researchers from Texas A&M University recently showcased superior tensile superelasticity by fabricating a shape memory alloy through laser powder bed fusion, nearly doubling the maximum superelasticity reported in literature for 3D printing.
    https://phys.org/news/2022-05-3d-printed-memory-alloy-superior-superelasticity.html
    In the future, the researchers hope their discoveries will lead to increased use of printed nickel-titanium shape memory alloys in biomedical and aerospace applications.

    New path
    https://phys.org/news/2022-05-aircraft-production-technology-strength.html

    Scientists from NUST MISIS have developed a method of producing composite parts for the aerospace industry, which has increased the strength of finished products by 15% due to a combination of laser technologies and isostatic pressing. The results of the study have been published in The International Journal of Advanced Manufacturing Technology.

    Those are tiny engines compared to what we're used to seeing today with those large Ultra High ByPass Turbo Fans on modern Airliners.

    I know we have the A380 but do you think there is a market for more large passenger craft like that one? Can they go bigger or is there a point there it is not practical both financially and from a design / safety point?

    Given the current market that has all Airline Carriers wanting 2x Engines for maintenance cost efficiency over 4x Engines; you'd literally have to design around that point.

    2x GE9X engines could potentially power such a plane.

    Add in a STARC ABL aft mounted Turbo Electric Fan for that extra efficiency / thrust

    STARC ABL is exciting in that it can do this:
    10% improvement in fuel efficiency is a BIG deal in the Aviation world.
    And having a smaller 3rd Propulsor mounted on the tail could increase safety margins incase one of the main engines fail.

    For a A380 rival, it would definitely have to be a modified 747X where the upper hump is fully stretched back.

    With the STARC ABL Electric Motor Propulsor on the aft of the fuselage, you'd need a T-tail instead of the traditional tail setup. Personally, I want a 3LS (Lifting Surfaces) configuration to maximize fuel efficiency. Add in a set of Canards or frontal stub wings right behind the cockpit area to help alleviate the weight imbalance when in flight and be more fuel efficient.


    The Top Deck would need to be single Aisle with 3-3 seating configuration
    The Bottom Deck would need to be Double Aisle with 3-5-3 seating configuration
    I estimate a Total Maximum capacity of 805 Passengers in pure Economy configuration.

    Given number of 747/A380s s in long term storage or being scrapped what does that tell you?

    then look up the A350 and 777x.

    Not sure I'd like to try flying (or in) one but it does stand out:)

    The day's of 4x Engine aircraft for Long Haul Commercial Aviation is DEAD.

    2x Engines are what's absolutely required due to the updated regulation for long range flight, so it's now the standard.

    The Demand for long range travel is there, ergo the A350 vs 777x and it's "High Capacity" passenger load out while using 2x engines.
