Roscosmos called the weaknesses of the American Crew Dragon


The state corporation Roscosmos called the weaknesses of the reusable manned spacecraft Crew Dragon, created by the American SpaceX. Russian experts identified a number of problem areas and published their findings in a departmental journal "Russian space".


Experts noticed that the liquid engines of the emergency rescue system of this ship are located right behind the wall of the cabin. Attention was drawn that the crew is in close proximity to toxic fuel. This has raised serious concerns about a possible danger. After all, the explosion of Crew Dragon, which occurred at a ground stand in April 2019, confirms the validity of such doubts.

The insufficiently comfortable sanitary conditions of the American ship were also noted. On Russian Soyuz spacecraft (crew of up to 3 cosmonauts), the toilet is located in a special compartment for domestic needs.

Astronauts flying on the shuttle complained that the toilet area was separated by a symbolic screen during each use. But if the sealed shuttle cockpit had a volume of 74,5 cubic meters, then the new ship has only 10 cubic meters, and the toilet is still behind the curtain

- explained in the material.

Experts added that the cabin of the American ship is designed for seven astronauts and significantly more than the descent vehicle of the Russian Soyuz. At the same time, the Americans reduced their crew to 4, since they are no longer required. In this regard, the ship seems oversized.

It is summarized that with the advent of the Crew Dragon, Americans have gained a compact and more reliable ship over a decade of effort, the operation of which is much cheaper than the shuttle. For example, during the launches of Space Shuttle (the last was in July 2011), 14 astronauts were killed, and Crew Dragon has a crew rescue system that can be used at any stage of the flight.

    The insufficiently comfortable sanitary conditions of the American ship were also noted. On Russian Soyuz spacecraft (crew of up to 3 cosmonauts), the toilet is located in a special compartment for domestic needs.

    But only if you make a reusable capsule ship, it cannot have any separate household compartment. In the Russian “Federation” there will be the same layout of the toilet “with a curtain” as on the “Dragon”, otherwise there is no way to do it.

    At the same time, the Americans reduced their crew to 4, as it is no longer required. In this regard, the ship seems oversized.

    Instead of 3 retracted passenger seats, an additional load can be installed, so there is no need to talk about “oversize”.

    Experts noticed that the liquid engines of the emergency rescue system of this ship are located directly behind the wall of the cabin. Attention was drawn that the crew is in close proximity to toxic fuel.

    Firstly, tanks with toxic fuel are located in the service compartment located at the bottom of the ship. Between these compartments is not a cardboard wall, but a multilayer partition. In addition, each Super Draco engine is enclosed in an individual sealed enclosure. Again, these engines are used not only for emergency rescue, but also for the regular movement of the ship and maneuvering. Since the ship is reusable, they will, by definition, be built into its hull. By the way, shunting engines and tanks for them with the same toxic heptyl at the Federation are also built into its hull.

    I looked through the original article, the impression - they would have to beat their hands. They would ask RT to share the experts once they themselves do not know how.
    https://www.roscosmos.ru/media/pdf/russianspace/rk2020-04.pdf

    As for the "shortcomings", as far as I understand, there will be two compartments on the Eagle, one metal for people, the second composite for the engine, but if the BABAH happens, what's the difference? Everything is nearby. Is the toilet behind the curtain? How to name what is on the right photo? Apparently this is it. No matter how much I looked, I did not see any references to a separate bathroom with a jacuzzi.


    There in the article there is a mention that the Americans promised the first manned flight in 2015, then in 2019, I think they are not lying, but who heard both of this? And about Roscosmos, all these unfulfilled promises are heard. Now "Roskosmos" experts say that "Eagle" is being created for a flight to the moon, and for flights to the ISS they will make a light version, they say, "Orion" needs to be leveled. But they will still do the "lightweight" version first. no

    By 2023, tests of the Angara-A5P manned rocket should begin in Russia. And at the same time - the ship "Oryol" in the version for the delivery of astronauts into orbit of the International Space Station.
    At the same time, "Eagle" will be "loaded" to a heavy version for flights to the moon.

    And on May 5, "China tested a new generation of manned spacecraft." I started Mask earlier, but who heard about this?

    In terms of information, the Americans did everything.

      They (the Chinese) launched it (the new Chinese ship) in May in an unmanned version - the Americans did this with their "Cru Dragon" a year ago.

        I know, I had in mind before launching SpaceX, the proposal was a bit wrong. It was understood that the Chinese program remained in the shadows, however, like the Boeing.
        How do you worry about them. lol
        By the way, here again they attempt to “mask” the Mask, they say, SpaceX is the brainchild of the Pentagon.
        I looked, I found this document here, I have not delved into it yet. Your opinion on this issue is interesting. yes

        https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20040161462.pdf

        On the NASA website, the description indicates that this is a comparison of the old NASA program (Bantam) and two DARPA programs (Falcon and Rascal).

        And Musk himself is so far engaged exclusively in peaceful space exploration, though, together with the military, but these are such trifles, right? Just think, in April I took part in the exercises, winked and in February too. repeat

          If SpaceX were the “brainchild of the Pentagon,” Musk would not have sued the US Air Force when he won the right to launch military satellites from them.

          And what is surprising in the fact that he collaborates with the Pentagon? Since 2017, he has launched satellites into orbit. This time he made available his satellite network.

            You never know, suddenly the guy wanted more, or maybe they decided to "legalize" the cooperation. In any case, the halo of the “shirt-guy”, spending exclusively his money on peaceful development, has faded.

            No wonder request I also see nothing surprising in the fact that the Pentagon was at the root of the Falcon program. It’s not me who told me that they finance everything exclusively at their own expense. winked

              laughing He never had such a halo. No one denied the help of NASA and the military at first, no one denies a significant (but not prevailing) share of government orders even now. But this does not negate the fact that he also invested dofig of his money.

              You never know, suddenly the guy wanted more.

              What more? Above zero?

              I also see nothing surprising in the fact that the Pentagon was at the root of the Falcon program.

              And now more about financing the development of ultralight Falcon by DARPA:

              Space Exploration Technologies Corporation (SpaceX) has been awarded $ 8M by the Defense Advanced Research Projects Agency (DARPA) and US Air Force to demonstrate highly responsive, affordable launch capability.

              As much as 8 million dollars)) Well, just fabulous bucks) laughing

                That is, you want to say that DARPA allocated 8 million for your project and then spin around, as you want?
                You once said something like that - the burden of proof lies with the approver.
                It is very interesting to see the arguments. Any information on the termination of the DARPA Falcon project?
                He invested his money "dofiga" too? True? And how many?

                What more? Above zero?

                More than one project. The Pentagon funded the creation of the Falcon, but Musk wanted to launch other satellites besides his own. This is a completely different project.

                As much as 8 million dollars)) Well, just fabulous bucks)

                This is just confirmation that there was funding. We will say that this is not because DARPA does not publish information?
                With the same success, it can be argued that hypersound is developed exclusively at the expense of companies. It is unlikely that you will be able to prove the opposite and present reporting to the MO on the allocation of funds. repeat

                If literally, then no, I didn’t tell, but we have already talked about this topic. You can remind a little. yes

                So Uncle Sam at SpaceX and was - no one denies this. At first, the company really lived off of funding from NASA allocated under the COTS and CRS programs. (ISS cargo support). At state launches, the company also generated the necessary reliability statistics for its missiles. And then, in 2015, it entered the market of commercial launches. After that, the share of government orders in the total number of launches decreased, the share of commercial orders increased.

                Information about Uncle Sam’s participation is incomplete, don’t you?
                Here are some more sources of company financing:

                The source of financing is the contributions of investors and the Mask himself, as well as the profit received from orders.
                A profitable project is SpaceX itself and their main direction (launches on Falcon-9).

                SpaceX has no dumping and government subsidies.

                SpaceX was financed from the budget only once - when they won the competition (on a competitive basis, by the way) for the creation of the spacecraft and spacecraft for the delivery of goods and people to the ISS.

                (123) This is not the first time that SpaceX and the Department of Defense have joined forces.

                - and? The Ministry of Defense ordered the launch of its satellite, SpaceX completed the order for money. Where are the "subsidies" here?

                I gave you a link where it is written in black and white in the American edition, the representative of the Air Force claims that SpaceX and the Ministry of Defense are not cooperating for the first time. It is about using satellites for military purposes. Do you think that in such cases the financing comes from the company?
                But you persistently repeat, this is an isolated case. I don’t see any further delving into projects, I’m tired of looking for all these links every time.

                (123) Without government orders and overpriced payments, an enterprise is not viable.

                - did you audit SpaceX to confirm this? Do you have insider information about the financial condition of the company? Can you present?

    This is like looking for a speck in the wrong eye. And the truth, unfortunately, we have nothing to make expert assessments in this area .....
    You must be able to face the truth! Talk less, do more!
    And then it’s just a laughing stock! It’s good for them that ordinary people aren’t at all up to it now!
