    First stages separate at nearly same altitude and angle, Converting Soyuz-5 into reusable rocket by adding Baikal-style wings and gear should be doable.

    I think they already switched fuel type they plan to use on it to make it more reusable-friendly so they are definitely working on something. Question is what?

    No, I mean huge parachute for landing and some type of landing gear or airbags to put it on the ground softly in horizontal position.

    @GunshipDemocracy
    Apparently uses methane and not hydrogen as fuel, so the helium trick would not work. But nevertheless some ram air cooling may be theoretically possible, this in the end looks to have many points in common with that British project you mentioned some time ago.

    vertically as a booster check the vid/infographics Smile No this wont be ramjet AFAIK but I didnt see official news yet. SO far only about turbojet Sad

    if technically yes, then still formaldecision an dmoney is needed. Will Rogozin say ok?  depending of costs ...

    what is cheaper? the whole expedition to reclaim danged stuff, stuff repair right? and howm many days it shall be repaired?
    Baikal AFAIK is jettisoned on 50-60km. No heat shields needed. Flies back as a drone and automatically lands on Vostochny.  Can be refilled and reused the next day. And this is what you call expensive?!

    Wow, that is VERY cool. Good to see the Russians can do good CGIs too Very Happy

    So this is apparently a definitive version of Baikal. The original apparently used a RD33 engine to land, interestingly it was placed apparently in the top of the nose with its thrust pointing front and downwards, why would that be? Aerodynamic stability problems due to the design?

    But don't loose the faith Gunship, we will see the cooled ramjet version of this sh*t someday! Laughing

    Actually it would be a huge advantage for this concept both because of the savings in oxidizer and avoiding the need for an additional engine for the landing phase, I agree with you.

    BTW good link about the Baikal:

    Have to agree with Gunship on this one. The controllability of the conventional landing approach alone is enough reason to give it a go. If in the relatively near future you can use an air breathing engine the airframe could largely maintain the same concept. Not exactly sure that the provisions for the parachutes etc. needed to ensure a safe landing are much lighter and smaller than the extra weight incurred by the Baikal due to wings, landing gear, turbojet etc. But I have already seen somewhere a concept that could work:

    https://www.youtube.com/watch?v=mwmLbELEnGg

    Minute 4:00  Cool

    Two additional considerations:

    1) What does it mean that it can place 600 kg in Sun-synchronic orbit, how does it translate into other altitude-related orbits like LEO, GEO etc.?

    2) Why is this new superlight reusable system meant to be used from mobile launchers??? Does it have "secondary" applications maybe?  Suspect

    Very cool but sadly without a prototype, more rubles are needed Vladimir! There was a similar project in the US some time ago, also with a conical shaped rocket. Didn't really understand from the article what kind of engine was going to propel it, which in the end is the critical part of any single stage launcher.

    Man, I was answering PapaDragon, he mentioned he liked parachutes to land these reusable launchers. On minute 4:00 of that video there is a very cool rocket-assisted parachute that lands tanks relatively soft, I found that a good example of a simple system that could achieve what he said.

    I wanted to understand how 600 kg to SSO would translate to LEO, GEO etc. SSO is not altitude defined apparently but payload capability of a launcher is, at least AFAIK

    Sea launch? Well that does not sound like a secret weapon but maybe you are right Very Happy Sorry for the ignorance, that should ease reaching different types of orbits or something?

    IMHO they dont  have much choice if not pre-cooled hybrid one. And anyway Russia ahse to build reusable space plane - to catch /repair satellites and also as a space bomber.  X-37  Will it be Korona? dunno

    aaaaa oki but still drone solutions reusable is much cheaper and also better for marketing too.

    after wiki for sn-synchronous-orbit:
    Riding the terminator is useful for active radar satellites, as the satellites' solar panels can always see the Sun, without being shadowed by the Earth. It is also useful for some satellites with passive instruments that need to limit the Sun's influence on the measurements, as it is possible to always point the instruments towards the night side of the Earth. The dawn/dusk orbit has been used for solar-observing scientific satellites such as Yohkoh, TRACE, Hinode and PROBA2, affording them a nearly continuous view of the Sun.

    They all were on 500-800 km

    Not showing any video! Very Happy I was not understanding why the mobile launchers for the Baikal. Since this is good for weapons (relocation) and was not seeing the benefit for commercial launches, was half-joking that maybe the launcher could have a military use, that's all

    This looks good.. finally some good news from Russia space program.. now we need good news too in the super heavy carrier projects.. all this things is what makes Russia Great again and help Russia makes headlines world wide and get world wide big support recognition for years if not decades.


    In more good news Russia developing a lazer mammoth cannon.. Very Happy



    https://sputniknews.com/science/201806101065288031-laser-cannon-space-debris/

    Probably this was what Putin was mentioning in the last question/answer conference of other Russia new
    developments that will be announced very soon....  Cool

    Make no mistake this IS the MOST IMPORTANT project of Russia for the defense of the nation .. if it is ambitious
    enough it will be. Because all this S-400s and S-500s will be near obsolete defenses dealing with Massive Nuclear attacks from NATO , with S-500s /s-400s facing thousands of decoys and Jamming.. it will always cause problems.
    It is simple impossible to seal the nation airspace and seal any nation space zone ,with rockets interceptors.. since not only very expensive but very difficult too to intercept a nuclear armed ballistic missile that become hundreds of targets in Radars after it eject its multi entry warheads..  each decoy will look identical to the original missile ,so to shutdown 1 Trident missile for example ,you could end needing dozens if not hundreds of S-500s missiles if all its defenses /decoy /warheads deployed..  Rockets interceptors are not really efficient way of intercepting Multi entry warheads..armed with a hundred of decoys..  Mid course interceptor ,to target tridents way before the warheads separate is much safer way..  but for doing that you need a large and heavy navy armed with mid course interceptors (as NATO have) to intercept ballistic space missiles way before they get close to Russia.
    So the most ideal way to secure your country from a ballistic nuclear attack  will be either deploy Laser cannons in space or deploy it on land.

    Maybe were Russia scientist got the inspiration?  Laughing



    Jokes aside ,eventually if Russia could pull it ,and develop a very very Powerful Laser cannon either on land or space or both , this will eventually for US to got to the negotiating table with Russia ,since a very strong energy weapon system will neutralize NATO Trident missile program ,its space rockets way before they reach Russia ,with a very high probability of success , this will make next to useless the Ohio Submarine fleet..and allow Russia to
    have for the first time.. the ability to strike US with very big Nuclear warheads while at the same time stay safe from NATO tridents missiles or others similar programs.

    IMHO to far reaching conclusions. It is like US is not investing in new developments. If Russia invests in hypersound rockets US cannot? if Russia invests in laser weapons US is not? c'mon.

    As for debris Russian can always reclassify any US satellites'  constellation as debris Smile

    I doubt that a nozzle. Looks like an aerodynamic spoiler to keep airflow from ripping off folded wing during flight.


    Also, more I look at this thing more I am certain that they can design strap-on version of wing/landing gear setup for Soyuz-5.

    ...........

    Standard rocket launch, return to runway is with wings.

    Soyuz-5 will have standard hardpoints for connecting multiple rocket cores so developing wings and landing gear add-ons that could fit on those should be simple enough if concept proves feasible.

    Easier (and less stupid) than designing new reusable rocket from scratch.

    I still think that parachutes are far superior approach but whatever....


    Is it possible to make parachutes strong enough not to damage the rocket stage when it lands?

    what is cheaper? the whole expedition to reclaim danged stuff, stuff repair right? and howm many days it shall be repaired?
    Baikal AFAIK is jettisoned on 50-60km. No heat shields needed. Flies back as a drone and automatically lands on Vostochny.  Can be refilled and reused the next day. And this is what you call expensive?!

    Have to agree with Gunship on this one. The controllability of the conventional landing approach alone is enough reason to give it a go. If in the relatively near future you can use an air breathing engine the airframe could largely maintain the same concept. Not exactly sure that the provisions for the parachutes etc. needed to ensure a safe landing are much lighter and smaller than the extra weight incurred by the Baikal due to wings, landing gear, turbojet etc. But I have already seen somewhere a concept that could work:

    Minute 4:00  Cool

    Two additional considerations:

    1) What does it mean that it can place 600 kg in Sun-synchronic orbit, how does it translate into other altitude-related orbits like LEO, GEO etc.?

    2) Why is this new superlight reusable system meant to be used from mobile launchers??? Does it have "secondary" applications maybe?  Suspect

    The billions needed to create reliable landing software(plus god knows how many years and billions in landing gear tests) massively outweigh the cost of the voyage to reclaim parachuted rocket stages.

    I doubt that a nozzle. Looks like an aerodynamic spoiler to keep airflow from ripping off folded wing during flight.


    Also, more I look at this thing more I am certain that they can design strap-on version of wing/landing gear setup for Soyuz-5.

    Believe me, it is the nozzle of the RD-33. The engine is located in the nose.

    In my experience the SW development is the cheapest one... tooling, prototyping, testing, industrialization is when the money really needs to flow massively in a project. For instance, take the PAK-FA: let's say that a PAK-FA prototype costs 100 million dollar (just an order of magnitude, in line with expected unit price even when prototypes are more expensive than serial units). Calculate how many programmers you can have working for how long with that amount of money. And the autonomous landing is a known issue, so no breakthrough in control technology needed to implement it.

    As for the tests needed, agreed they can be expensive, but are the parachute tests going to be free of costs and risks? Besides, the success of your launching method depends on it being economically competitive with other reusable concepts being developed and reliable in the long run, otherwise you will not get orders for launchings or you will need to offer them on a loss...

    ok so development new tools technology, spacecrafts and knowledge is not economical O for Russia but for west, Japan, Korea, india or China it is?! interesting concept indeed

    actually it is not. And it is growing. For Grippen or F-35 class of fighter there is 20,000,000 lines of code. Sensor fusion, AI, soft defined radios cyberseucrity and in RT. Bad software costs ennormously - programme delays (vide F-35 is lat mainly due to SW...) .

    Once I've seen a SEI presentation about cost of quality of software. There were % SW investment of programme cost. For either B-2 or F-35 (dotn remeber but vote for F-35 Smile it was like up 35%. That is the reason SEI created CMM methodology - for military and space SW mainly.

    I'll re-post these as they are currently topical in this thread - the proposed methodology for re-use of the Zenit-based strap-ons of the Energia stack
