There has been a similar heat shield concept under development by NASA for several years, although much smaller (inflatable cone shaped). When the JPSS mission launches (planned for the next month or so), there is a payload called LOFTID (Low-Earth Orbital Flight Test of an Inflatable Decelerator). The concept has been tested several times at various altitudes in the atmosphere, this will be the first attempt to do reentry with it. You can choose this option in KSP as a supplemental heat shield.

Would it only be a Big G payload - or might something else be deployed from the payload adapter behind the Gemini? This is a Bono concept with which I was not previously familiar - so I was assuming that the Gemini was just used for guidance - was going to ask whether this vehicle could be launched uncrewed as a cargo craft only. I'll have to do an Internet search for ROOST to get the full picture.

I've definite concerns about the practicality of that landing... a hot-air balloon landing at sea is going to have horrific problems with wind. And once down it seems to still ride very high out of the water... you're presumably relying on the balloon (ballute?) to keep the rocket out of the saltwater, but you'd need to get it at least partly deflated quickly to reduce sail area... towing it as-is would be challenging.

Note that when it landed it had four (4) sea anchors deployed, the 'aft' most one would remain in the sea to provide drag and help with control. It's not going to 'tip-over' per-se since it's essentially a large hydrogen balloon as the ballute if filled and pressurized by hydrogen bleed off from the propellant residues.

Heh, that piston-engined Sikorsky helikopter dates the concept very nicely - nice touch! (I looked it up - 1953!) Inflatable hypersonic decelerator doubling as a hot air balloon is positively nuts, but might actually work - makes the whole job of propulsive landing unnecessary. But, we never succeeded making a SSTO craft, even winged and partially air-breathing. What was "secret sauce" here - extremely light airframe? (The propellant was supposed to be hydralox - I suppose that those engines would not be much different from F-1... Speaking of which, a tiny nitpick: the exhaust was too bright initially for hydrogen burning engines, IMO) Another beauty, Hazegrayart!

(Note the SSME produced 418,000lbs, while the RS-68 produces 660,000lbs of thrust at sea level) The ballute is stainless steel and Rene41 cloth weave of which small batches had been tested. The boost engine are still in there, yes :)

It's a hydrogen, not hot air balloon. It uses bleed off gas from the propellant residues to inflate and pressurize. The ballute was to be made of woven steel fibres with a special refractory metal fiber 'overlay' of the lower (and most heated) sections. Assuring it drifts down the 'targeted' spot was an issue since it had no control so the idea was to 'target' the equatorial 'doldrums' to avoid weather issues if possible. The downside was this would mean a long tow period or using overseas bases to process the booster and then ship it back to the US by a large barge.

Yes it's similar to the current idea of inflatable heat-shields/decelerators many space agencies are working on today.

It's carrying a Big Gemini. Basically an enlarged Gemini for more crew

Excellent animation and cool concept from that era. Sadly at the time we did not the computer simulations we have today, because it is obvious that the payload would have been minimal at a very heavy cost. Contrast that to SpaceX Falcon and soon to be Starship that use a 2nd stage (reusable in starship) to make access to space at a much reduced cost as needed with massive payloads. Also the balloon in the video, although correct in scale, seems extremely small for such large rocket... I think it would have dropped like a rock... not a soft hot air balloon landing.

It's payload was kind of meant to be 'minimal' in general (note it delivered a Big Gemini capsule and cargo pod into orbit) the idea being a single stage would be easier and cheaper to refurbish than multiple stages. (Still an argument of the SSTO crowd today :) ) It landed like a balloon because at that point is IS a balloon. The ballute is filled and pressurized with excess hydrogen gas from the propellant so once in the lower atmosphere it would tend to 'float'. Hence needing the sea anchors to hold it in place and why it sits almost complexly out of the water. (The engines would have been out of the water too)

@@TomTheGrouch Bono's designs were quite often "optimistic' in the extreme. NASA (and others) have done quite a bit of inflatable research and they can be quite robust AND lightweight. No doubt this was pushing that envelope but it's probably the least of the issues :)

Why not attach the fairing pieces to the inflatable and recover them as well?
@randycampbell6307
@randycampbell6307 2 жыл бұрын
Leaving them attached would create aerodynamic 'hot spots' on the ballute which is just a woven steel mesh and inner hydrogen liner and would cause drag issues during reentry that might throw the vehicle off trajectory. (Or worse cause it to tumble) As SpaceX found out, fairings are pretty cheap and recovery can be not-so-cheap so expending them makes more economic sense.

Is it really so worth not having multiple stages that you make a gigantic rocket to get a tiny capsule to orbit 😅

In theory? Yes, or so the argument goes but keep in mind that's a LH2/LOX stage which is why it's so big. At the time LH2/LOX was the only propellant combination that could 'close' a case for SSTO, today we know different BUT the issue with SSTO is always that the payload would be vastly smaller than a two-stage system but the argument was that recovering and maintaining only a single stage might (note that point) be more cost effective. And the payload isn't that 'small' really considering it's a Big Gemini and payload module which comes in at around 40,000lbs all-up.

I just cannot understand how American politics can keep throwing way billions after billions when we could have re-usable launch vehicles like this, making space so much more accessible and so many opportunities to learn and expand into space and find new ways to make things and new resources to put people to work. We are really missing out.

There's no way that thing doesn't tip over in the water... the plumb drops can't weigh much for the unforgivable addition of dead mass. The rocket motors however should be the majority of the mass left. That should lower the center of mass a bunch. If so, it seems like it should ride much lower into the waterline.

The ballute is actually (at this point) a hydrogen balloon so it doesn't "tip over" because it's 'mostly' lighter than air and 'floating' hence the soft touch-down and how it's towed back.
