Rogozin answered Mask in absentia to words about the high competitiveness of SpaceX reusable missiles

151

An absentee exchange of statements regarding the effectiveness of Russian and American spacecraft continues between Roscosmos and SpaceX.


Earlier, the head of the American company, Elon Musk, stated that the reusable nature of missiles created in the US reduces the competitiveness of Russian-made missiles. According to Musk, today SpaceX possesses 80 percent reusable rockets, and Russia - “0%”.

The head of Roscosmos Dmitry Rogozin does not believe that on this basis we can talk about a decrease in competitiveness on the part of Russia. According to Rogozin, the use of reusable rockets for space flights does not make it possible to be cost-effective in comparison with the use of Russian-made disposable rockets for the same purpose.

В interview KP radio station Dmitry Rogozin said that about half of all fuel volumes of the Falcon-9 rocket are spent on returning its stages back to Earth. Because of this, the mass of the payload that an American missile is capable of carrying is also significantly reduced.

Additionally, the high cost of inter-missile launch service from SpaceX is noted.

In any case, the level of competition, especially when it comes to commercial launches, will increase. And here we need to draw conclusions about how our country is ready to increase this level of competition in the near future.

          This is not only with us, it is all over the world, I have never heard of a poor bureaucrat or a deputy from abroad. Tales of our liberals about a former worker who has become a deputy somewhere in the West cause laughter, I always wonder where this former worker takes money for an election campaign, how will he work that money out for sponsors?

          Where do you come from?) The data on the proportion of workers you have in the crowd are in the form of documents. Who what what is worth. You workers decided to level off? What else? Maybe a long personal car?
          No need to compare Roskosmos and the company Mask. It’s just pointless, these companies live in fairly different conditions, and are not too similar. The only thing that unites them is this line of activity. But putting them in trying to compare on separate indicators is too much. Really it is not visible that this dispute / fight of the companies is started intentionally. In the information field, a confrontation between companies is created intentionally.

              Well, of course, for example, the productivity of a worker at the Cummins plant in the USA is eight times higher than the worker at the YaMZ Russia plant, but if you take into account that for the Cummins, CPG, cylinder head, Blocks, gears, camshafts and crankshafts are produced at third-party enterprises, mainly located in China, and all assembly nodes for YaMZ are produced at the enterprise and if we compare the performance of only the assembly shop, then the productivity at YaMZ is 1,3 times higher, I’m directly involved in the production of foreign diesel engines and in this regard e is far from a novice.

                Back in 2017, Russian Prime Minister Dmitry Medvedev noted that Russians work more than in OECD countries, “and the results are very average,” calling among the reasons for this state of affairs: lack of incentives for development due to lack of competition, technological lag, lack of managerial competencies of company and government leaders, lack of investment and lack of legislation ....
                Low labor productivity is also associated with poor automation of production, lack of modern equipment, low qualifications of the workforce

                The competitors from ULA (Boeing in alliance with Lockheed) are engaged in the assembly from the purchased ones. They have fairings from Switzerland, Rocketdain and Russian engines, avionics and others, also from third-party companies, etc.

            You can find another 50 reasons why this is so, but it is a fact. A Russian worker on average works more hours than an American, but produces less. Due to poor management, because of antediluvian equipment, because of the low level of professional education, so at least Musk pays his workers more but in the end rockets cost him less.

            It is not only a matter of bureaucracy; it is a matter of cutting government spending. This is just a fact: when developing a similar project by a government agency such as NASA, the total cost of the project is much (almost several times) higher. And in today's conditions of confrontation in the Congress of Democrats and Republicans, it becomes practically impossible to get a dimensionless development budget.

    Dmitry Rogozin said that about half of all fuel volumes of the Falcon-9 rocket are spent on returning its stages back to Earth. Because of this, the mass of the payload that an American missile is capable of carrying is also significantly reduced.
    And what exactly because of this significantly reduces the cost of subsequent launches, Mr. Rogozin forgot to mention. Over time, we will come to reusable systems, but, alas, again in the role of catching up. There are no people in the leadership who are capable of evaluating non-standard ideas and, moreover, risking translating them into iron. It’s good, however, that this did not happen with hypersound. And Roskosmos has long turned into a stagnant swamp.

      Если бы все так гладко было у Маска, то США давно перестали покупать у России ракетные двигатели РД-180. Однако они покупают их уже 10 лет и потребности остаются. В любом случае у США есть еще "батуты" - до МКС они может и не допрыгнуть, а вот Голливуд допрыгнет до Луны 100%. А все эти заявления Маска направлены лишь на создание нужно информационного фона у акционеров, инвесторов и американских налогоплательщиков. Сомневаюсь, что ответ Рогозина кого то там интересует, индекс цитируемости таких заявлений в американских СМИ нулевой, его даже переводить не будут.

            С точки зрения экономической целесообразности ракеты Маска более эффективны, несмотря на гораздо более высокие зарплаты в SpaceX по сравнению с российской космической отраслью. Они дешевле в производстве за счёт использования более продвинутых технологий, они дешевле в эксплуатации за счёт многоразового использования. Недаром после появления Falcon 9 цена на запуски побежала вниз, сделав немалую дыру в бюджете "Роскосмоса".

              If someone wrote about this somewhere, this does not mean at all that it is so in reality. Just think about the meaning of returning the combustion chamber and gas generator (the main, most expensive components of a rocket engine), and then imagine a bunch of problems associated with their disassembly, troubleshooting, inspection and assembly. It is clear to any techie that it is easier to do one-time than to catch and plant it is not clear that with dubious reliability.

In general, the customer will now fly only with the Mask.

                5 launches with a foreign load, some of which used to fly on Protons / Arians.

                  Hmm, how long has the estimated life of the satellite at the geostationary station become dependent on the LV, and not on the iron of the satellite itself?
                  If the satellite is in low orbit, and it was launched higher than necessary, then yes it flies longer, but again, its life depends on iron, and not on the pH.

                    The fuel is wink

                    As explained Arabsat Executive Director Khalid Balkheyur (Khalid Balkheyour) in an interview with SpaceNews, the company chose the Falcon Heavy rocket to launch its latest satellite to extend its lifespan.

                    “We needed to increase the satellite’s life, and we decided to use Falcon Heavy,” he said.

                    He also said that preliminary calculations showed that the satellite will receive greater momentum from Falcon Heavy and this will extend its life to 18-20 years.

                    Arabsat now has nine satellites in orbit, and Balkheyur said that they are now developing another satellite and expect that by the fall of this year, the company that will build it will be presented.

                        He was thrown higher than Arian - he saved fuel on the final positioning wink Therefore, the number of corrections has increased.

                        Everything is simple. They have restrictions on fuel that is consumed constantly:
                        By periodically turning on the small thrust engines (north-south correction to compensate for the increase in orbital inclination and west-east to compensate for drift along the orbit), the satellite is held at the designated standing point. Such inclusions are made several times every 10 to 15 days. It is significant that for the north-south correction, a much larger increment in the characteristic velocity (about 45-50 m / s per year) is required than for the longitudinal correction (about 2 m / s per year). To ensure the satellite’s orbit correction throughout its life (12-15 years for modern television satellites), a significant amount of fuel is required on board.

                        He saved some of the fuel due to the pH with the best characteristics, that is, the length of the segment that he made to the point on his engine was reduced. This allowed to extend the service life (that is, until the fuel runs out) by 3-5 years.

                        The spacecraft launches the satellite into the calculated orbit, and therefore the satellite itself does not need to increase it. The correction already in orbit is again independent of the launch vehicle. Since if the launch vehicle did not bring the satellite into a given orbit at a given speed, then the launch is considered partially successful and not calculated. And your example is not about anything.

                        These satellites (platform) are initially made so that on their engine puff at the desired point. This is a calculated successful launch. The rocket brings it to the maximum possible point in a given orbit. Then he puffs at 36000km on his own. Arian gave less - and therefore the last Arabsat spent more fuel to get to the calculated point. Khevik gave more - therefore, the CEO of the company is quite a calculated extension of the resource and is going to launch a new Arabsat with Mask.

                        What is the actual news, not from the mask, but from the CEO of the launch customer’s company wink .

                        I have not read about these satellites, but there are moments:
                        1. Mount the horseradish block (horsepower engine and large fuel supply) on horseradish and yearn for it; it’s easier to make it a separate part of the shot after it has worked.
                        2. A separate unit reduces the weight and variety of equipment installed on the satellite.
                        3. The resource of satellites is often measured not by fuel on board, but by the resource of power supply, solar panels, batteries, leaks in the circuit and the cost-effectiveness of the equipment itself.
                        4. In geostationary orbits, the effect of braking on the atmosphere is minimal and corrections are not often carried out, again, pulsed low-power engines are used there.

                        По сему я не вижу причины увеличения ресурса спутника на 20%. Это всеволишь их хотелки. И так сказать "ненавязчивая" реклама флакона, не более. hi

                        PS. I forgot to add, marching (accelerating) engines do not use in correction.

                        Following launch, Arabsat-5A separated into a geosynchronous transfer orbit. It then use an apogee motor to raise itself into geostationary orbit... Once it reached geostationary orbit, it underwent testing before beginning operations at a longitude of 30.5 degrees East, where it replaced Arabsat-2B.

                        Another heavy satellite, already from SSL
                        EchoStar XVII was launched by Arianespace, using an Ariane 5ECA carrier rocket flying from ELA-3 at Kourou. The spacecraft was launched at 21:36 UTC on 5 July 2012.

                        In fact, the inhibitory impulse is already given against the movement and, proceeding from your application, you first need to deploy the satellite, and then slow down .... Many unnecessary operations.

                        Have you tried to change the direction of movement? There is enough speed there, only time passes a lot, it does not immediately go into the gravitational field. And for that matter, the first satellites did not reduce it to the GSO, so they can fly for a very long time, everything else, when braking and lowering the orbit, I gradually fall to the ground, burning in the atmosphere.

                        201 × 37 688 km For example, a typical GPO, it is enough to slightly lower the orbit at the lower point to begin braking about the atmosphere and fall.
                        35 786 km x 35 786 But GSO orbit, you need to spend a lot of fuel to reduce the orbit to below 200 and begin to fall
                        And any speed is fuel, and fuel is a payload, leave more to go into the atmosphere, deliver less cargo to the point

      And here comes some kind of Musk who agrees to do the same, taking into account over-price state orders, for only 180-220 million one way and about 100 with a return. Of course, Boeing and ULA are straining their people and pushing as they can from the trough. Who else will buy the Heavy Delta for 420 million ???

      Take last year, Musk made 6 launches on a commercial basis with different customers. 4 flights to the ISS via NASA. And 1 paid demo flight for the military.

      What did his main competitor do for the fattest orders?
      flew for 420 million on Hevik in January for reconnaissance
      flew on the middle delta for the US air force
      flew on the middle delta for the US air force

      that’s all. No one else needs these over pricing suitcases. Atlas (where RD180) is not better:
      flew with a U.S. Air Force satellite
      flew with Starliner on the ISS

      Antares with RD-181, where for every launch with a swan NASA pays more than 9ka + Dragon:
      flew with a swan on the ISS
      flew with a swan on the ISS

      Nobody needs this Antares anymore, in the history of 0 launches for money or from other customers. And again, 3 more launches were paid, they say that Antares-Lebed will not be extended.

    The head of Roscosmos Dmitry Rogozin does not believe that on this basis we can talk about a decrease in competitiveness on the part of Russia. According to Rogozin, the use of reusable rockets for space flights does not make it possible to be cost-effective in comparison with the use of disposable Russian-made rockets for the same purposes.

    Unfortunately, the journalist’s assumptions can only be of weight today, when 1-4 space speeds can be achieved through a rocket engine. With the advent of other principles of moving in space, reusable devices will become more in demand ...

    about half of all fuel volumes of the Falcon-9 rocket goes to return its stages back to Earth. Because of this, the mass of the payload that an American missile is capable of carrying is also significantly reduced.

            These are all dreams and unverifiable statements. Kerosene engines are slagged, it is highly unlikely that they can withstand repeated starts. On ground tests, the engines of the first stage of Merlin 1C worked out only 170 seconds, the engines of the second stage of Merlin 1D - 370 seconds. It does not smell particularly reusable.

    In an interview with the KP radio station, Dmitry Rogozin said that about half of all fuel volumes of the Falcon-9 rocket are spent on returning its stages back to Earth.
    In an interview I didn’t hear this for some reason, but if he really said that, then he 100% lied. smile
    Out of approximately 410 tons of fuel refueled to the first stage of the Falcon 9 FT, only 23 tons (i.e., about 5,6%) will be required to return it.

      This is all so for a loud word from tearing off the covers - the geniuses of control and production of the space sphere in whom landings on the new cosmodrome began earlier than takeoffs. And every year the criticism of these figures towards Mask and his company becomes more and more miserable - and becomes more like a clownery.

        Falcon-9 in its current version is a heavy class rocket. When starting with the return of the stage, half of the fuel goes into returning this stage to Earth. belay

    Если США и сбивают цены на космические старты, используя поддержку со стороны правительства, то делают это с умом, выбивают конкурентов наверняка. Даже в таких вот словах тов. И. Маска звучит эта "ковбойская тактика". Как говориться, не руби с плеча, отвечая на такие заявления... (Тут не до "батутов", и в детстве надо было больше вестернов смотреть, чтобы не попадать впросак). Затем, когда конкурентов не будет или они полностью станут подконтрольны НАСА, или просто безнадежно отстанут в своем развитии в силу иных причин, тогда США станут диктовать свои условия, свои цены, свою волю всем потребителям. Всё укладывется в концепцию "великой Америки", ничего личного, только бизнес.
    Я задаю себе вопрос: С.П.Королёв, он что, из-под палки работал? Он что, ради денег или славы был просто одержим идеей космических полетов за пределы земной атмосферы, на Луну, на Марс? Он что, фон Брауну отвечал на страницах газеты "Правды", наконец, "Браун, ты не прав"? Нет, нет и нет!
    Мы прекрасно знаем биографию Циолковского, Жуковского, Королева, Цандера, Глушко и др., без кого невозможна была бы наша космонавтика. Главное, что ими двигало -- это стремление познать новое, быть на пике прогресса (это не патетика), а не разрядить кольт в конкурента, а потом быстро его перезарядить, потому что следующий на подходе. Анализировать надо не то, как американцы используют "многоразовые" ракеты, а то, как они умеют личную выгоду, свой бизнес совместить с прогрессом и движением вперед.

    Reusable launch systems have already paid off when landing and returning to the Moon and Mars, because there is no spare rocket for a return start, I carry all of my things with me. Musk decided to try it on Earth, more or less happened.

    Once I read about the combined scheme out of the corner of my ear: a one-time accelerator simply throws an object into orbit, and reusable devices that are constantly hanging in orbit will reach the 1st space one. What is the benefit of such a scheme - niazilil, because reusable devices must first be slowed down to the speed of the object, and then again accelerated together to 1KS. We are talking about satellites, with 2 and 3KS clear.

    Не совсем так, уважаемый. В 1930-х годах в США разразилась Великая депрессия. Вторая по счету в этой стране. Американцы поняли, что циклическое повторение таких событий -- это факт, а не выдумка К.Маркса и др. экономистов-философов. И чтобы избежать катастрофических последствий в будущем, защитить властьимущие кланы в США, правительство этой страны приняло попытки решения этой проблемы. Прежде всего упор был сделан на развитие наукоемких производств и финансового сектора, который обеспечивал долгосрочные вложения в такие проекты и производства. Разумеется, вторая мировая война также послужила катализатором этого процесса. Страх перед тем, что кто-то может опередить США в технологиях, которые могут в том числе и уничтожать людей, сыграл здесь свою роль. И все-таки такие институты как институт Гэллапа (образован в 1935 г.), пресловутый "Римский клуб" (1968 г.), система стратегического планирования в целом и те организации, которые это планирование осуществляют, а самое главное, система внедрения НИОКР в производство, позволили американцам к 1980-м годам опередить практически все страны мира в научно-техническом развитии. Основным конкурентом тогда был СССР. Его ловко убрали с дороги, использовав при этом алчную партийную верхушку, развалившую свою собственную страну.
    Беда американцев том, что они не могут объединить вокруг себя страны и континенты, а пытаются, по сути, продолжить колонизацию, которую в свое время они осуществляли в рамках Северной Америки, а теперь осуществляют уже в масштабах Земного шара. Используют при этом те же методы: распространение "огненной воды", "завшивленных одеял", подкуп, обман и т.п. атрибуты освоения "Дикого Запада".

            This is a cheap propaganda trick. T.D. and Roscosmos did not provide any of the defenders with all its statements.

            Ilon, as the creator and owner of SpaceX, can speak authoritatively for his company.
            Here is an article in which he is interviewed:
            https://www.popularmechanics.com/space/rockets/a9504/musk-spacex-now-has-all-the-pieces-for-reusable-rockets-15985616/
            According to Musk, as of September 2013, SpaceX rockets needed to reduce payload by 30% to return to the Earth cosmodrome and 15% to return to the offshore platform.
            Even then, not half of the talk was discussed.

            Today is not 2013, but 2020. Now SpaceX has F9 block 5. The take-off mass from version 1.1 to block 5 rose from 506 (and 318 in version 1.0) to 549 tons.
            Today, especially not about half of which we are not talking.

            Rogozin even theoretically lied; I don’t understand at all in astronautics, but I could find on Wikipedia that, according to the Tsiolkovsky rocket equation, theoretically, the fuel for landing will fluctuate within 10%. This is enough for me.
            Rogozin lied. And everyone who says the opposite lies. Including you.

        It is you who protect. He is wrong at least in that place (leaving aside the lies about half the load) that if SpaceX does not just compete, but crushes the space industry on all fronts (while losing, according to Rogozin, half the fuel in the return configuration), then the same Falcon 9 in a one-time configuration with the growth of this lost half of SpaceX all the more crush and bury Roskosmos.

        Rogozin either simply is stupid and does not understand, or (more likely) he considers the population of the Russian Federation so brainless that they can sound such a mess, and no one will understand that in his own words he even more shows the superiority of SpaceX.

            Apart from the missions, when landing was not planned, those that generally planned to land.
            Until 2017, when the landings were worked out in test mode, 10 out of 16 landings were successfully completed. Since 2017, when SpaceX officially announced that the landings would be considered a regular routine operation, 3 out of 43 landings failed.

            For the entire time of launches (with and without landings), SpaceX did not complete only 2 missions. One of which exploded before the start.
