Pic one is the 1.5 stage NLS base configuration... quite similar to the Saturn V, especially the 6 F-1 engine variant that was proposed in one of the upgrade studies I summarized over in the scale section...


Pic two is the wind tunnel model of the NLS 1.5 stager...


Pic three is the base config of the NLS 2 proposal...


Pic four is a graphic of the NLS launcher family...


Pic five is the NLS HLV proposal base config... this is basically the genesis of all the present SDLV proposals, in using SRB's to loft an inline shuttle ET derived core vehicle powered by SSMEs...

Pic one is from the NLS base heating model study, which was referred to often in the study of the exhaust plume impingement and radiative heat load studies of Ares V... This one is the standard 4x2 engine layout...


Pic two is another layout, this one the so-called "six pack" SSME layout...
Kinda reminds me of "Tantive IV"...


Pic three is the base geometry of the NLS HLV...


Pic four is the wind tunnel model of the NLS HLV...


Pic five is various "shuttle C" concepts through the years, including the "shuttle Z" concept powered by a pair of RS-68's IIRC... problem is that cursory study has shown that going larger than about 7 meters on the payload shroud is a non-starter due to controllability and aero-effects issues, so these enormous payload fairings that are larger than the ET are just fantasy material...

Here's the original proposal for "shuttle Z" from 1989-- powered by four SSME's and the SRB's at liftoff, staging to a new third stage powered by a cluster of "SSME-derived" engines (probably the STME expendable SSME variants in vogue at the time modified for airstart). For reasons mentioned previously the 33 foot payload was a wild daydream...


Pic two is OSC's proposal for an SDLV-- SSME powered SRB boosted core, with a Delta IV second stage and some sort of (likely RL-10 powered) SEM stage for lunar ops...


Pic three is and RD-180 powered ET derived booster proposal...


Pic four is more daydreaming/rocket porn... It's a VERY nice render of a notional but completely unfeasible THREE SRB single launch Ares V type vehicle for the Constellation lunar mission... the weight of three SRB's would sink this thing 30 feet deep into the Florida swamps on the way to the pad...BUT it WOULD be a neat kitbash to make to a Quest Future Launch Vehicle...


Pic five is the RBS flyback reusable booster system... a parallel staged flyback first stage lifts an expendable second stage above the atmosphere, where it stages and the second stage delivers the payload to orbit, while the flyback stage returns for a runway landing... interesting proposal...

Pic one is some "super kerolox" concepts... Saturn V, six F-1's, six F-1A's, ten RD-180's...


Pic two is some various options from a study looking at various shuttle propulsion systems and concepts-- pressure fed LRB's, STME powered LRB's, flyback LRBs (the White Knight looking thing on the right)...


Pic three is a comparison chart of some of the proposals made around the NLS compared with the Titan IV...


Pic four is comparing some of the NLS options to the Atlas...


Pic five is analysis of some of the concepts for a common core vehicle study using various engines/boosters combinations...

Pic one is the AJAX using 2, 4, 6, or 8 Atlas V LRB's ala the Russian "Vulkan" proposal, sort of an American "Energia". This graphic is from simcosmos over on the nasaspaceflight.com/forums who does excellent graphics work for the 'orbiter' flight simulation program...


Pic two is the standard AJAX 440 (4 SSME core engines, 4 Atlas V LRB's, no upper stage).


Pic three is showing the "tilted" Ariane V style nosecones that early aero-studies showed would be helpful in managing shock wave interaction and aero-heating effects as compared to the standard "straight" SRB style nosecones...


Pic four is some various sidemount shuttle HLV payload fairing designs that were looked at around the time of the Augustine Commission...


Pic five is the HLV configuration that was presented before the Augustine Commission...

Pic one is the Augustine Commission proposal for a sidemount "shuttle C" style crew/logistics vehicle for ISS... The Orion mounted on top, the ISS payload mounted below in the fairing, the SSME engine "pod" permanently attached to the ET in place of the shuttle orbiter... while a viable idea which would minimize changes at KSC, the expense of building a new thrust structure/fairing to emulate the attach points of the shuttle would have been very expensive, and the performance is compromised by having the engines off to the side instead of underneath like the inline versions... also the abort options for an Orion trying to get away from a disintegrating stack while lighting off their LES tower next to a partially loaded oxygen tank was NOT good...


Pic two is the flight profile of the crew/logistics sidemount vehicle...


Pic three is the sidemount evolution slide from the Augustine presentation IIRC...


Pic four is the Block II HLV sidemount lunar cargo launcher and flight profile...


Pic five is the evolution of the SDLV inline launcher concept over the past few decades... some placed the SSME's off to the side in the "shuttle" location in a recoverable pod (like the "Ares" proposal from Zubrin's "Mars Direct" proposals a number of years back). This would have recovered the SSME's but added more complexity and expense in the design and construction of the recovery pod and the recovery and refurbishment operations themselves. According to folks at NASA, the cost effectiveness of reusability "is a myth"...

Shuttle C...


An evolved Shuttle C-- five segment boosters and an enlarged payload carrier...


Augustine Commission slide of the Shuttle SDHLLV...


Another pic of the carrier vehicle and the upper stage and Orion...

Sidemount SDHLLV carrier cutaway mounted to the ET...


Another of simcosmos's fine "orbiter" add-on's, this one emulating an AJAX style vehicle, outfitted with Delta-IV core size boosters with enlarged thrust structures large enough to fit 4 RD-180's...


A view of the NLS 1.5 stage "Hyperion" design at booster sep...


A dimensioned drawing of the SRB-X...


SRB-X leaving the VAB on the crawler for the pad... I doubt the existing crawler could have handled the weight of 11 SRB segments in the two 4 segment boosters and the 3 segment center booster, along with the weight of the Titan upper stage, Centaur G prime, and payload and fairing... almost certainly it couldn't, because even the Ares V with ten SRB segments was too heavy, and the core of the Ares V would be moved EMPTY unlike this third SRB...

A pre-ESAS proposal for SDLV... back when "spiral development" was the buzzword... LOL


Buzz Aldrin's "Starlifter" concept... (a new kitbash for those Estes "shuttle express" kits...)


The very early "Team Vision" Jupiter concept for shuttle derived-- this morphed into what became the "DIRECT" Jupiter concept... these early proposals using RS-68(B) (which was a 'theoretical' regeneratively cooled manrated RS-68 IIRC) and using multiple stages were non-starters... as was the retooling for 10 meter tanks...


A more detailed view of the Team Vision Jupiter II...


Just for farts and giggles, here's the Team Vision "Jupiter III"... COMPLETELY unrealistic but an interesting thought exercise nonetheless... Start with souped up RS-68's in a secondary thrust structure on the base of the core stage, fuelled by the two outrigger ET's on either side, themselves being lifted by a pair of SRB's EACH (4 SRB's!) The SRB's burn out and stage, and shortly thereafter the two depleted ET's separate, and the secondary thrust structure with the souped-up RS-68's jettisons, so the core stage's J-2X engines can ignite and power the core until it's propellant is depleted, then staging in-line to another upper stage powered by a pair of J-2X's... THAT would make a neat kitbash of a couple Dr. Zooch shuttle kits and some extra tubing and parts...

Here's some more of the Team Vision Jupiter III for giggles...

The Jupiter III liftoff under the power of a cluster of souped up RS-68's and FOUR SRB's...


The Jupiter III on its way from the VAB to the pad... they're gonna need about six more crawler trucks under there and at least double the strength in the MLP to support that thing (unless it's built of unobtainium)!!!!


The Jupiter III at ET sep... drop them both and the souped up RS-68 lower thrust structure on the bottom of the core... toss the payload fairing too now that you're out of the atmosphere... see the 4-pack ISS module stacks in the payload rack... ISS 2 in one launch, anyone??


The Jupiter III at SRB sep... drop four at a time...
