    MAKS airshow outside Moscow cancelled in 2023, to be held in 2024 — source

    MOSCOW, May 24. /TASS/. The MAKS aerospace show, which is held in the city of Zhukovsky outside Moscow, has been cancelled, a source at the organizing committee told TASS on Wednesday.

    "MAKS will not take place this year. It is scheduled for 2024," the source said adding that the final decision would be approved on Thursday, May 25.

    "Yes, MAKS-2023 will not take place, preparations for the flight program have already been cancelled," another source close to the organizers told TASS.

    The 16th International Aviation and Space Salon MAKS-2023 was to be held in Zhukovsky in the Moscow Region on July 25-30, 2023.

    That is a shame, but they will likely do more business next year because that will be after the US elections by which we will know better the time table for the west to abandon their nazi heroes.

    ..plus it gives another year for Russian miltech to complete the total eradication of banderite NATO forces and thereby prove its mettle to the potential buyers in the non-Western world. I suspect that MAKS 2024 will be full of foreign buyers with full shopping lists and bulging pocket books. russia

    Tupolev Design Bureau solved the problem of airframe heating when flying at hypersonic speeds
    04.11.2023

    PJSC Tupolev has patented a hypersonic aircraft with a combined power plant, including two turbojet engines running on jet fuel and another one on cryogenic fuel. About it reports TASS with reference to the description of the invention to the patent.

    The invention is designed to solve the problem of airframe heating when flying at supersonic and hypersonic speeds, caused by the interaction of external surfaces with the oncoming air flow.

    “When a turbojet engine using cryogenic fuel operates, the aircraft accelerates to hypersonic speed. At the same time, due to the increased friction of the outer parts of the airframe with the air, they are intensively heated and to continue a long flight at hypersonic speed they need to be cooled. For this purpose, cryogenic fuel is supplied from the tank through pipelines to the hottest parts of the aircraft airframe and engine, as a result of which intensive gasification of cryogenic fuel occurs in the pipelines. This process is endothermic in nature, in which heat is absorbed from the heated parts of the aircraft airframe and engine. The heated cryogenic fuel turns into gaseous form and is fed into the engine combustion chamber and afterburner to create thrust,” the description explains.

    In a hypersonic aircraft, thermally stable T-6 or T-8B grade fuel can be used as aviation kerosene, and liquefied natural gas or liquefied hydrogen can be used as cryogenic fuel.

    Among the authors of the invention is Honored Designer of Russia Valery Benderov, who in 2012-2019 served as program director - chief designer of the multifunctional flight modeling complex (LMK-214), leading design engineer at the Tupolev Design Bureau.

    Nice... but small mistake... he airflow does not heat the surface parts of the aircraft through friction, it does so through compression.

    The aircraft pushing its way through the air compresses the air which heats the air up... like when you use a compressor or bicycle pump to pump up a tire the air gets hot.

    Watch the section starting at the 15 minutes mark. This is where he specifically talks about aircraft in development.

    In the rest of the video they talk about how improvements in processes and technology can reduce the time to get a new aircraft operational, the challenges in recruiting people, AI, how the UAC works now that the Sukhoi and MiG bureaus are under one roof, and things like that.
