BE-4 to replace RD-180: in the United States announced the solution of problems with turbopumps of rocket engines

The American company Blue Origin has solved the problems with the turbo pumps of the BE-4 rocket engine, which is being developed to replace the Russian RD-180 engines. This is reported by Ars Technica with reference to the statement of the executive director of the United Launch Alliance Tori Bruno.


According to the report, after correcting the malfunction, the engine was returned for testing.

This is always a good point in the development program because it means that your important technical questions are over.

- said Tori Bruno, adding that now the company can focus not so much on the creation of the engine, but on increasing its production.

As it became known earlier, in early July of this year, Blue Origin delivered the first American BE-4 rocket engine to United Launch Alliance. At the same time, it was emphasized that the engine is not a serial one, it is planned to be used for testing together with the Vulcan Centaur launch vehicle, the first flight of which is scheduled for 2021. The second BE-4 engine was also to be delivered in July this year.

Recall that the American BE-4 rocket engines are planned to be used in the first stage of the Vulkan launch vehicle, which should replace the Atlas family of rockets equipped with the Russian RD-180.

At the same time, it is noted that although the US Congress calls for a complete abandonment of the Russian RD-180, this is unlikely to be possible until 2024. The main reason is the high cost of the American analogue and the unpreparedness for its mass production.

    Sometime this should have happened. But the merikatos will have to pull on our eRDeshkas after 2025, at least.

      Manned only.

      In general, Americans can live remarkably well without Atlases. This was shown for example in 2019:
      Atlas5 - with military satellite
      Atlas5 - with Starliner

      Все.

      This year a little more:
      Atlas5 - SolarOrbiter, where NASA is on withdrawal under the ESA AMC contract.
      2хAtlas5 - with the military
      Atlas5 - with rover

      And that’s all, by the end of the year the rocket might fly, or it might not. At the same time, all this could be replaced by the military mega-expensive Delta from the same manufacturer, AMC - Falcon.

      By the way, Beck is lucky enough to have 10 satellites of detailed photography. The main one is from Canon, and 9 Flokov4e. This is where progress has come, now such small satellites are able to take such pictures and live for three years. By the way, before Floki1-3 was taken out on the Soyuz with additional cargo.




      Well, the fireflies promise to fly firmly and clearly in December. We have already worked the table to launch readiness, burned the stage.

        ... Firefly has signed a Launch Services Agreement with Spire Global (Spire) in connection with the launch of the Lemur spacecraft on the Alpha launch vehicle. The agreement provides for the launch of the Spire spacecraft on multiple flights of the Alpha launch vehicle during the contract term. Firefly also contracted Geometric Space Corporation to fully utilize the payload capacity of the Alpha launch vehicle.
        Robert Sproles, Senior Director of Satellite Planning and Operations at Spire, said: “The addition of the Firefly Alpha to the Spire launch program further expands our expansion opportunities for our world's leading nanosatellite constellation. We look forward to many successful flights with Firefly partners. ".

        Planned on December 22 with a possible transfer window until January 31.

          Yes, well, to fly - I mean to roll out the rocket to the start. And then everything can happen. The weather will turn bad. Or something will break (the first start is the same). Therefore, yes a window of more than a month for transfers.

      This is definitely a breakthrough, because the American company Blue Origin has solved the problems with the turbo pumps of the BE-4 rocket engine. NPO Energomash solved these problems back in the 1990s.
      NPO Energomash has a miserable handicap in solving rocket engine problems for more than a quarter of a century (practically one human generation). wink

        Well, BE4 is still methane LNG. And this is still difficult in Russia. Dmitry Olegovich speaks:
        The repayment of the debts of the "Khrunichev Center" limits the capabilities of "Roscosmos", in particular, to create promising rocket engines, RIA Novosti reports a statement by the state corporation's general director Dmitry Rogozin.

        «While we are paying off our debts, we are losing invaluable time that could be used for promising projects. Such promising projects are the creation of a methane engine, hydrogen theme", - said the manager during his visit to the Khrunichev Center.

        According to the head of Roscosmos, "the methane engine will enable us to reuse carrier rockets." Rogozin is sure that it is possible to create such a power unit for “a couple of years, but this requires funds that are not yet available"As they are invested in the financial recovery program of the" Khrunichev Center ".


        So, while Rogozin is looking for money, the Americans are already approaching the second launch, and on the horizon is an innovative third, which is 96% done without people, in a robotic complex and on 3D printers.

          The methane + oxygen pair, in my opinion, has less thrust, with greater fuel requirements, than hydrogen + oxygen.

            Hydrogen is expensive. It is the hydrogen Delta Heavy that is now the most expensive rocket in the world. And a simple medium is twice as expensive as Atlas and 9k without reuz.


            LNG provides a cost-thrust balance, while providing a high resource with a minimum of inter-flight maintenance. That is, an ideal option at the current technological level for a cheap, mass-produced rocket with a reuse for 10-15 flights.

              That is, LNG is only needed for a reusable stage (kerosene slags the engine).

          1. KBKhA is developing the RD-0177 engine, a prototype of the RD-0169 aircraft. Earlier in KBKhA the engine-demonstrator RD-0162D2A was created and passed firing bench tests.

            1) Well, let's take a demonstrator from BlueOrigin 2015 (and at the end of the year there was an accident there with the explosion of the stand), prototype burns March 2018


            2) There is a fundamental difference. The traditional approach is to adjust components to innovative / modern technological processes. Relivity's approach is to make a rocket for a robotic process technology with minimal human involvement in production. They have the whole economy of the project on this. Minimum people (about 500 at the stage of mass production) - a new rocket every 60 days.

            Also the engine, they originally made the engine and made compromises in favor of maximizing 3D printing and robot assembly. There is no guarantee that it will shoot - but nevertheless, it is a small step towards something new. This is how progress moves.

              OSI RD-0162D2A took place in October 2017. The engine was created as part of the second phase of a Russian LNG engine for a launch vehicle. Based on the test results, the engine was disassembled and its fault detection was carried out.

              The third stage of the creation of an LNG engine is proceeding successfully - a series of firing tests of a model gas generator have been carried out, experts have studied the processes of mixture formation with various options for the nozzle head. Now they are working on the combustion chamber. Next year, they will assemble and start the HSI of the ready-made RD-0177.

      The Lockheed-Boeing Alliance is a direct competitor to Space X. Musk doesn't want to supply his competitor with engines.
      Therefore, the Alliance turned to another billionaire for help - Bezos, the owner of Amazon. Bezos has more mundane plans - he is not interested in the Moon and Mars.
      He needs engines and rockets to power his beloved Amazon and for space tourism.

      Well, there is an obvious misunderstanding of the general situation.

      The US has several tough competitors. ULA - through lobbying, holds 2/3 of the state order. Boeing + Lockheed has 3 missiles - Atlas5 (the cheapest), Delta4 (horse price tag under 200 lam), DeltaHavi (380-400). They are holding their cake with their teeth and do not want to give it back. New ULA rocket - methane Vulcan on BE4.

      There is Northrop - but while their OmegaA is still not flying, Antares (also with Russian engines) is not needed by anyone. A total of 1 launch per year under the supply program with a swan. And NASA is exploring the possibility of dropping Antares into the graveyard by transferring Swan to Atlas5. This will increase the carrying capacity, and the cost of the rocket has already become equal, due to the piece assembly.

      There is Musk, who makes 2/3 of the launches under commercial contracts. And they don't really want to let him into the state order.

      There is Bezos - who has everything very leisurely. DoD even canceled the certification launch contract. For the dates are at 23. Engines are the same BE-4. There are shoals on the rocket.

      There is also a wagon of private traders, from Astra and Rocketlab to Fireflies and Relativity (these are the ones that will print methane rockets on 3D printers).

      What difference does it make if everything has already been paid for? We will finish supplying them with what we will do for our missiles. Development of new engines based on the RD-180 is underway. At one time they were even burned with methane, there are still many opportunities where to move.
