    Оригинальный однако на 3700 км. летает, а не на 740. Интересно, там пропеллер поставят, или вентилятор будет?
    Ну и главное

    The company also won a US$650,000 grant from the US Department of Energy’s Electric Aircraft Program to help develop a propulsion system last October.

    Отработка технологий. British Aerospace смотрит другие электросамолёты с чистого листа.
    Малое плечо с массовостью европейской аэродромной сети более благосклонны для ВС с "батарейками". Естественно в Сибири и на северах они особо бы не разлетались.

    Wright Electric says it can get all-electric versions of the BAe 146 family of regional jets into commercial service by 2026. In a November 4 announcement, the start-up said it will replace the aircraft’s four turbofans with electric motors to support flights carrying up to 100 passengers on sectors of around an hour with a rebranded aircraft called the Wright Spirit.
    Plans call for the development of the new motor, inverter, and propulsion fan to be complete by the end of 2022, in time for a converted 146 to fly with a complete electric propulsion unit (EPU) replacing one of the existing turbofans in 2023. The Wright team aims to be flying a technology demonstrator with four EPUs by 2024, as it prepares for type certification in 2026.
    In September, the company said it had started testing its two-MW electric motor as part of a plan to develop a 186-passenger airliner with 800-mile range called the Wright 1. Jeff Engler, CEO of Wright Electric, said this program, which would require a more powerful motor, will still be pursued with a 2030 service-entry date. UK-based low-cost carrier EasyJet and Viva Aerobus of Mexico are committed to partnering for the Wright 1 project and both operators have said they will provide input for the new BAe-146-based program.
    In the U.S., Wright says, the all-electric regional airliner will serve routes such as New York to Boston and Washington, D.C., and San Francisco to Los Angeles. In Europe, Paris to London and Frankfurt, Germany, are identified as early-adopter routes; Doha, Qatar, to Dubai, UAE, is being eyed in the Middle East and, in Asia, the airliner could serve one of the world’s busiest scheduled routes, between the South Korean capital of Seoul and Jeju Island.
    Wright announced the initiative to coincide with the United Nations’ COP26 climate change conference being held in Scotland. “The world needs to shift to real-zero emissions, not net-zero or using sustainable aviation fuel, Engler told AIN. “Operators have told us that if you want to start replacing the typical Airbus [A3230] and Boeing [737] aircraft that they are using, it has to be with something that can operate at the same altitude, at jet speed, and that is big enough [to have the same operating economics as narrowbody airliners].”

    Other companies such as Sweden-based Heart Aerospace and Tecnam (in partnership with Rolls-Royce) are working on much smaller all-electric regional airliners, seating 19 and nine passengers, respectively. Wright has concluded that these will not offer sufficient commercial return to operators and that getting a clean-sheet, all-electric model to market would take until into the 2030s. It sees a conversion program around an existing airframe as being a far quicker route to market.
    According to Wright, its two-MW motor is around four times more powerful than existing competitors and has around double the power density at 10 kW per kilogram. It says that its inverter will have low rates of heat loss and store energy more efficiently than other designs to support increased aircraft range and payload with the same energy storage capacity.
    Initially, Wright intends to install its motor within the nacelles of the existing Lycoming LF502 engines and use its fans. Engler indicated that his company will likely partner with other aerospace groups to update both flight deck and cabin systems in the 146 family of aircraft, which were in production between 1983 and 2003.
    Initially, the motor will directly drive the fans, which Engler noted is a more efficient EPU architecture than using a gearbox. That said, Wright hasn’t completely ruled out the introduction of a gearbox-based system, since this would support more revolutions per minute.
    Other technical decisions that are still being considered include whether to base the EPUs on hydrogen or aluminum fuel cells. While hydrogen is lighter than aluminum, it has greater volume, which presents storage challenges. Wright is also weighing various concepts regarding how the fuel would be loaded onto the aircraft.
    Wright expects to convert mainly the Avro RJ update to the 146 design that British Aerospace introduced in 1993. Engler said Wright is still considering how the conversion business model will work in terms of whether the company, its customers, or potential retrofit partners will be responsible for sourcing airframes.
    More than 200 of the 146 aircraft are still in service worldwide, and around 100 of those are the more recent Avro RJ version. In-service aircraft are supported by the BAE Systems Regional Aircraft business based at Prestwick, near Glasgow, Scotland, where the COP26 conference is being staged.
    Engler acknowledged that it could prove challenging for airlines to get air operators certificates covering the out-of-production type. He said that avionics systems will need to be updated as part of a move to reduce the training burden for today’s commercial airline pilots.
    “Aviation has committed to net-zero carbon emissions by 2050, but Wright is committed to a 100 percent reduction in all emissions starting in 2026,” Engler stated. “Because we built the world’s largest aerospace propulsive powertrain, we can build the world’s largest zero-emissions retrofit directly serving the world’s busiest routes.”

    Вот вам технология - дальность в пять раз меньше (это обещают), причем наверное он взлетает (и садится) с максимальной посадочной массой (что поднимает вопрос к безопасности), так что пока не будет революции в батареях, все это попил и откат. Также открыт вопрос зарядки - быстрая убивает батареи, а медленная непригодна для нормальной эксплуатации авиапарка.

    Это вы про меня? Я не так чтобы русский, а термин "откат" он тоже не в России придуман. Это дело везде любят.

    А «революция в батареях» появится по мановению волшебной палочки?
    Она появится только в результате развития фундаментальной науки и НИОКР, но никак не путем использования неподходящей технологии за счет трудового народа.

    VirPil, не обижайтесь. Думаю ежу понятно, что никто завтра его на регулярку не поставит. Это R&D.

    Просто удивляет постоянный негатив - какая вам по большому счету разница если кто-то что-то разрабатывает?
    Ну и грант во-первых минимальный по объему, во-вторых грант от органа, который должен подобное как раз и поддерживать, и в-третьих кому кто что откатил? Что там можно откатить? Вы проецируете :)

    Да я и не собирался ))).

    какая вам по большому счету разница если кто-то что-то разрабатывает?
    В данном случае никакой. Но в целом вся эта "зеленая" тема и за мой счет тоже. Например в моем городе несколько лет назад сделали каршеринг на Рено Зои (где я на нем и покатался). Муниципалитет тоже вложился из моих же налогов. Конец немного предсказуем Потому и возмущает. А в итоге это может вылится в ограничение или резкое удорожание перелетов. В Глазго сейчас вроде звучали призывы заморозить дальние перелеты на уровне 2019.

    VirPil, я за Грету не топлю, во всей этой Extinction Rebellion истерии преобладают в основном эмоции и отсутствие прагматизма, но ничего плохого в ограничении выбросов и чистом воздухе/воде не вижу. Пусть себе мастерят - с машинами получилось на ура.

    Я тоже. Но это еще надо считать с полным циклом производства и утилизации. Если сравнивать Теслу не с классом Д в две тонны весом, а с С или В, то картина уже не столько радужна.

    с машинами получилось на ура.
    Машину можно себе позволить заряжать всю ночь или день (а быстро только иногда).

    Emission-free flight is a central goal of civil aviation. Emission-free air transport could be achieved in the long term by converting hydrogen into electricity. This would enable the environment-friendly electrification of propulsion systems. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and MTU Aero Engines are focusing on a fuel cell propulsion system, which they will jointly develop and validate. A Do228 will be used as the flight demonstrator. On 5 August 2020, the partners signed a Memorandum of Understanding (MoU) at the DLR site in Oberpfaffenhofen.
    The MoU was signed by Rolf Henke, DLR Executive Board Member for Aeronautics Research and Technology, and Lars Wagner, Chief Operating Officer at MTU Aero Engines. “Although great progress in the performance and lifespan of fuel cells has been made in recent years, there is still a considerable need for research into their use in aviation,” said Henke. “This planned joint research-industry project is the first of many steps towards emission-free aviation.” Lars Wagner adds: “As things stand today, fuel cells utilising sustainably produced hydrogen offer the greatest long-term potential for realising emissions-free aviation. We believe that they could offer sufficient performance and range for regional, short- and medium-haul aircraft.”
    In order to develop and validate such technology, the partners plan to equip a Dornier 228 aircraft with a hydrogen-powered fuel cell and an electrical, single-sided propeller engine with over 500 kW shaft output, and flight test it over the coming years. Apart from water, fuel cells have no emissions and are highly efficient. The aim of the joint technology project is to develop a complete drive train suitable for aviation (power line) and its cooling (cooling line). The electrification of the powertrain is a core technology that serves to prepare a flying fuel-cell-based propulsion system. The partners are aiming for the maiden flight of the Do228 demonstrator to take place in 2026.
    DLR is managing the flight project and providing and operating the research aircraft. It is also responsible for the integration and certification of the powertrain. The research institute will also offer its expertise in the fields of flight testing and aircraft aerodynamics and aeroelasticity. In its role as a partner to industry in the joint project, DLR is therefore contributing its overall system expertise. MTU is tasked with the development of the complete powertrain powered by a hydrogen fuel cell. All work and integration processes will be carried out jointly and in close coordination. Up to 80 experts will be involved.

    “The flying test platform will provide important insights that we can use for the further development of electric and hybrid-electric powertrain systems and reduce the ecological footprint of aviation to zero," said Henke. On behalf of MTU, Wagner added: “The development of an airworthy fuel cell and the experience and data acquired as a result, including in the fields of aviation regulation and certification, will prove vitally important to ongoing product development.”
