NASA Pitches Heavy Lift Vehicle To Congress

BJ_Covert_Action writes "Well, Congress demanded, last year, that NASA develop a budget plan and proposal for a new heavy lift vehicle in light of the Ares V cancellation. Recently, NASA gave Congress just what they wanted. On January 11th, Douglas Cooke pitched an interim report to Congressional members detailing the basic design concepts that would go into a new heavy lift vehicle. Congress required that the new heavy lift vehicle maximize the reuse of space shuttle components as part of its budget battle with President Obama last year. As a result, NASA basically copy-pasted the Ares V design into a new report and pitched it to Congress on the 11th. The proposed vehicle will require the five segment SRB's that were proposed for the Ares V rocket. It will utilize the SSME's for it's main liquid stage. It will reuse the shuttle external tank as the primary core for the liquid booster (the same tank design that is currently giving the Discovery shuttle launch so many problems). And it will utilize the new J-2X engine that NASA has been developing for the Ares V project as an upper stage. In other words, NASA proposed to Congress exactly what Congress asked for."

Killing Constellation was really about ditching that as no longer required so they could get serious about the V and the actual deep space equipment (whether it is for the moon, an asteroid, whatever). The problem that I see is that the mandate that they reuse as many shuttle components as possible means that they made some significant changes to the Ares V before giving it back to congress, namely reusing the SSMEs instead of RS-68. The SSMEs are amazingly efficient, but also amazingly expensive, so they don't fit on an expendable segment. Fortunately, they seem to have left themselves an opening to renegotiate that later, FTFProposal:

NASA is a huge fucking waste of money; however it occasionally spits out something reusable right now, and often spits out engineering knowledge that provides a foundation for something down the line. Rocket science is completely useless as-is; it quickly filters into smaller, simpler designs for ICBMs (also useless-- war is an immutable evil that always depletes the economy in the same way as making jobs to dig holes and then fill them in again or make lots of boots and then burn them) and more slowly into designs for launching satellites, before finally providing the engineering foundation for planes and then land and sea vehicles.

While it needs regulation, we do in fact need an enforced money sink for this kind of shit. Technological advancement is a trickle-down economics model: ideas for shit that's physically impossible in current technology are laughed out unless you have an instant moment of clarity with tons of new technology to quickly scribble down on paper. New technology that's basically useless gives you a fresh set of tools to implement new technology that's suddenly possible.

      Without an organization like NASA, we can advance neither as far or as fast as we can with their technological progress. Things we would naturally come up to would come more slowly; and some things would cost too much for any business to ever develop (i.e. research components that are only useful when put together, but are prohibitively expensive and pointless to research individually over time, thus would never be developed to be assembled).

This complicates the design and raises the cost of these particular SRBs. So, why design segmented SRBs in the first place? Well one rocket maker, Morton-Thyokol, now owned by ATK, made a design bid for the SRBs on the shuttle when it was first being designed. Unfortunately, after their bid won, they realized that their manufacturing plant was in Utah, and their launch site was in Florida. Super large rockets don't travel well by road or rail, so they had to segment the SRBs to ship them in parts to Florida.

      There are other issues as well. SRBs are hard to shut off once they are lit. There are workarounds for this problem, but, again, they complicate the otherwise simple design which makes SRBs so appealing in the first place. But all in all, the real problem is these particular SRBs, in my opinion, not SRBs in general.

      Manufacturing solid rocket motor fuel is, essentially, a casting operation: you pour the liquid into a mold, then the liquid sets into a solid in the shape you need (and the shape is critical in rocket motors). The trouble with the solid rocket boosters as used in the Shuttle is that they are so big you have to cast them in segments, then stack them and join them. Wherever there is a seam between the segments, the burning solid fuel tends to burn into that seam; this increases the surface area that is burning, which increases pressure, which increases burn rate, which increase pressure, ad explosium. It's a very difficult (meaning: expensive and risky) problem to manage, and as we found out with Challenger, cold temperatures can cause shrinkage which opens up those seams, changing the internal geometry of the motor. Multi-segment SRBs are just plain trouble.

      As anyone who has worked in large-scale casting can tell you, there are limits as to how much you can cast in a single pour. Your liquid is cooling even as you pour it, changing in volume as it cools. If you pour in multiple phases, letting it cool between phases, you're introducing seams, and subsequent pours can partially remelt previous pours, causing expansion in the previous seam and possible cracking (which are uncontrolled seams and surface area... if your solid core has internal cracking, there is a very high chance of explosion). And large continuous pours also have the potential for cracking as the early parts of the pour solidify and cure while the later parts are still molten. This, plus limits on how large a segment of solid rocket fuel you can transport without flexing (cracking) safely, is what puts upper limits on single-segment solid rocket motors.

      Solid rocket motor technology on large scales comes mostly from ICBMs. You want solid motors on your ICBMs, as a single-segment motor is more rugged than a liquid fueled motor, your launch vehicle is readily transportable and self-contained, does nto need a refueling infrastructure, and is always ready to use (keeping liquid fuels in tanks for a long period of time is dangerous and high-maintenance). ICBMs don't have to throw 60,000-plus pounds of payload into orbit, therefore they don't need engines larger than can be cast in a single segment.

      Nothing wrong with SRBs for sub-orbital missions with moderate payloads, or orbital missions with small payloads. But for the mass that a heavy lift booster needs to throw into orbit and beyond, they just don't scale well.

      The sad fact is that the political and budgetary environment are constraints of problem-solving at NASA, just as surely as mass, temperature, volume, gravity and materials technology are constraints. Any viable proposal needs to take into account and address ALL constraints.

One of the main goals of DIRECT was to require as little development as possible before NASA could have an operational heavy-lift launcher, using existing SRBs, lower- and upper-stage engines, external tanks. Also, the DIRECT plan was to develop the J-130 ASAP, capable of lifting 75mt without an upper stage, before NASA proceeded with the J-246, which would add an upper stage

      I'll answer my own question. For a technology to become cheaper over time there has to be an incentive to improve the design. The strongest mechanism that creates incentives is a climate of strong competition. In the 1960's there was a space race and a race to build ICBM:s which created strong incentives to improve launcher designs. Spaceflight technology progressed rapidly. By the 1970's and onwards to today ICBM.s have been miniaturized and manned space exploration has become a beauty contest at best. Spaceflight technology is progressing at a ridiculously slow rate.

      If you want manned spaceflight to become cheaper you need to find a way to make it competitive again. Maybe it will be a space race to Mars between China and India, or some other nations, that achieves that. Maybe it will be commercial space firms competing to fly rich folks on space vacations. All I know is that it's not happening now. I doubt there is much that NASA can do to make it happen. NASA could start a space race to Mars or to colonize the Moon, but at this point in time nobody would take them up on it. NASA could buy flights from commercial space firms, but probably not enough to create a competitive market.

    Rather than using a cannon, a much better approach would be to use a maglev, combined with a small rocket. The maglev can actually get the craft up to mach 2 on the ground if the track is long enough.

    Probably a much cheaper approach is to continue the work on scram jets. They would allow as much as mach 24, though it would certainly be above mach 14. The ISS orbits at about mach 25, so, this approach would allow us to use a simple kick motor to get to ISS. In addition, it would scale much better than the cannon and have other uses.

      See the BFG for an even better choice for propulsion -- saves accelerating all that propellant down the track before burning it -- even if you did end up needing maglev for stabilization/guidance in the tube. (They think it can be done aerodynamically, I'm not convinced.) But neither option is particularly attractive for SHLV work, since they don't scale well. Basically, after you build your proof-of-concept/commercial launcher for putting satellites in LEO, you have to build a whole new system for HLV capability, then another for SHLV; with rockets, OTOH, there's reasonable commonality of components between multiple HLVs over a factor of 10 or more payload.

      Of course, long-term, we need truly cheap and high capacity LEO capacity, which IMO means partial-orbital-ring/launch-loop, but I think a rail launcher of some sort for light payloads with chemical HLV/SHLVs will be the best compromise until then.

  41. HLV needed? can it be successfully promoted? by k6mfw · · Score: 3, Interesting

    I think this whole thing is gonna die no matter how it is presented (which is too bad because all this great technology and we all still going to the same place Yuri Gagarin visited nearly 50 years ago).

    I believe it was Dennis Wingo who wrote a comment on nasawatch.com that proposing HLV is a non-starter. Reason is such a launch vehicle is so expensive there is no way such a program will be approved by congress. It would be nice to have a Saturn V class vehicle that can place 100 tons in one shot but if you ain't got the money, then do planning for lower cost lower payload rockets (there are several). Supposably Sean Okeffe, NASA administrator before Mike Griffin, as a longtime Washington DC politico understood this so didn't push for a HLV. But he was replaced by Mike Griffin (man o man you should read the rants about Griffin on nasawatch). I don't know all the details but enough to bring up some interesting discussion (new topic for /.?)

    I read on Wayne Hale's blog that OMB made the edict to Augustine Commission to not present any options that cost more than $3B which limited options "worthy of a great nation's exploration." Kind of reminds me of funding large programs, either put a lot of money upfront on development but save on operational costs, or skimp on development and have a more expensive operations cost.

    I think the biggest question that needs to be answered is why go back to the moon and on to Mars? Back in the 60s, we knew exactly why a HLV had to be built. It was needed for Apollo so we can beat the Reds to the moon. Otherwise if they get there first, they will plant the Soviet flag on the moon seizing the high ground and enslave the rest of world in Communism. Now that all may sound silly but if you read all the history, it was serious back then. However, looking back the Apollo program could have "failed" like the Soviet lunar program (Korolev never had the resources needed for a HLV and much of the Politburo argued among themselves), the USAF MOL never flew (it just kept getting more and more complex), and John Houbolt at LaRC was able to successfully get the LOR adopted (which was among a few key fundamentals to have Apollo/Saturn work without violating the laws of physics). Also note that Saturn V was built to fulfill a single task. It was too expensive for "routine" flights to the moon, and Ares V is trying to be "routine" which I can never see congress funding.

    I'd love to see us go back to the moon and see what the old Apollo sites look like now (and... what if they were to find the rovers on blocks with the tires missing?!?!). However, if I could wave the magic wand, I would direct NASA to do research and development in making access to space lowcost. So far all orbital access requires major bucks and a huge standing army just to get a small elite few into space (I'm not elite and I wanna go!)

    1. Re:HLV needed? can it be successfully promoted? by BJ_Covert_Action · · Score: 1

      Actually this raises a very interesting point. Do we even need an HLV to get to the moon? Or, for that matter, to Mars? Currently, we can launch manned capsules and cargo capsules like Dragon, Progress, Soyuz, the ATV, and the Japanese cargo craft (I forget the name) into LEO using our existing fleet of launchers. We can mount these types of capsules on top of Delta IV's, Delta IV heavy's, the Soyuz launch system, the Arianne V, the Atlas V, and the Falcon 9. The only thing that keeps them from getting to the moon and back is the lack of fuel reserves for another burn once they are in LEO. So do we really need an HLV to do a moon shot in one shot? There is nothing keeping us from assembling something similar to the ISS that acts as a fuel depot on orbit (or, for that matter, using the ISS itself). We could launch fuel into orbit in separate cargo craft than the manned capsules. We could launch manned capsules into orbit later. The two systems could dock on orbit. Fuel could be transferred to the manned craft. The manned craft could make a second trip to the moon and back using those fuel reserves.

      There are actually some proposals floating around to do just this. We could use Progress, at first, to test this system as the original Progress vehicle was designed to survive a moon trip. We could test the Dragon's capabilities to do the same thing when it is ready. We could use Centaur vehicles (also designed for lunar orbit) to send unmanned cargo to lunar orbit or, even, to the lunar surface. So why do we need to make a moon shot (or, later, a Mars shot) in one big oomph from a super powerful rocket? It may well prove to be more sustainable to stick to smaller rockets, launched rapidly in sequence, than it would be to design a super powerful rocket and man rate it. So yeah, definitely a debate worth having. Unfortunately, Congress doesn't tend to like proposals like this because it moves funding away from the industries currently located in their districts.

      Yes, this has been suggested because congress will never appropriate money for a HLV, and this is further highlighted with a recent NASA request turned down this week. So if you ain't got the money for a super rocket, you must make plans using smaller ones. Unlike during Apollo, they had money but they did not have the time (deadline was end of decade). Also docking in space was unproven and nobody had experience when LOR was decided in 1962.
