Here’s an article from “Future Life” magazine, May 1979, describing a Rockwell concept for a passenger module for the Shuttle. This could carry 74 passengers, a loadout that seems perhaps excessive until you realize that it was meant to transport the crews who would build the miles-long solar power satellites. If this concept is of interest, be sure to check out US Bomber Projects #06, the Solar Power Satellite Launch Special. There, another concept for a Shuttle “bus” was described and illustrated.

Continuing…

In 1985, the Space Shuttle program was already about a decade and a half old, the shuttles themselves were already starting to show themselves as “old tech.” It was clear that they would need replacing with a next generation of vehicle, and of course Rockwell wanted to build whatever “Shuttle II” came along… if for no other reason, a Shuttle II would make the Shuttle instantly obsolete and wipe out Rockwell’s Shuttle-based income. It was obvious that such a system would enter service sometime after the year 2000. Not, of course, very long after 2000. That would be nuts.

Interestingly, the illustration Rockwell used for the Next Generation Shuttle was not a Rockwell design, but a NASA-Langley concept for a small “Orbit-on-Demand” vehicle. If you’d like more information on this exact design, boy, have I got a deal for you: it was described and illustrated in US Launch Vehicles Projects #03.

In 1985, just as Rockwell thought that a case might be made for an Aft Cargo Carrier for larger-diameter payload to fit behind the Shuttle External tank, there were those who believed that a case could be made for a *forward* cargo carrier for even bigger-diameter payloads. This “hammerhead” payload shroud would be much more conventional than the ACC and would not need to deal with the thermal issues of getting baked by the SSME and RSRM exhausts. it would have to withstand aerodynamic forces, but those are much better characterized.

An advantage of the “hammerhead” was that it allowed quite sizable payloads, but at a substantial mass penalty. Details from other sources are sparse on exactly *what* payload, but one item illustrated is a space-based laser with a very large primary mirror. A NASA mission would be for a “very large space telescope,” a follow-on to Hubble with a much larger mirror. Pretty much what became the Webb.

This very concept was described further and illustrated with diagrams in US Launch Vehicle Projects #01. Why not pick up a copy?

Now available… the newest and biggest issue in the US Aerospace Projects line.

US Launch Vehicle Projects #6

Cover art was provided by Rob Parthoens, www.baroba.be

US Launch Vehicle Projects #06 is now available (see HERE for the entire series). Issue #6 is devoted to the launch vehicles proposed for the 1970’s Solar Power Satellite program. This required millions of tons of payload delivered into Earth orbit over a span of decades, with flight rates of several times per day for each vehicle. This program produced some of the largest and most ambitious launch vehicles ever designed, and was the last time that launchers of this size were ever seriously contemplated. Appropriately, USLP#6 is by far the largest issue of US Aerospace projects to date at over seventy pages, three times the size of a usual issue.

Topics in this issue include the Rockwell Star-Raker, several Boeing Space Freighters, the Boeing “Big Onion” Low Cost Heavy Lift Vehicle (antecedent and descendant designs), a Grumman two-stage HLLV, a Rockwell HLLV and “small” HLLV, NASA-JSC heavy lifters, a Boeing/Rockwell Personnel Launch Vehicle and a Boeing winged SSTO. Along with orthogonal views, a number of perspective diagrams are also included.

 

 

USLP #6 can be downloaded as a PDF file for only $9:

I’m in the final stages of US Launch Vehicles Projects #06, with a special focus on launch vehicles for the Solar Power Satellite program. Included there is a plan view of the initial NASA SPS, with Manhattan island for a scale reference. Why Manhattan? Because the SPS satellites were approximately the size of Manhattan, and thus Manhattan was used in schematics and art of the time to illustrate the scale of the program. But… who actually thinks in terms of Manhattan island as a unit of distance measure? Tell me that “such-and-such is the size of Manhattan,” it’ll mean nothing to me, as I’m sure it means nothing to the vast majority of people.

So… since this issue will arise again in future projects I’m working on, what alternatives to Manhattan are there to serve as scale references for structures twenty kilometers long?

Some further tinkering to the USLP06 diagrams. There will be further revisions (especially with Star Raker), but I believe this will be the complete set of vehicles shown. I had to split the set up into two separate files; the unified diagram set was causing my computer headaches. You might not think that 2D diagrams can overload computers that can render things in 3D, but you’d be wrong.

This latest effort has taken a *really* long time. Lots of work involved with this. As a result, it has been a long time since I’ve published anything else, and since my income is based on getting stuff published… yay, welcome to poverty. If you want to help out, consider Buying Stuff or subscribing to the Monthly Historical Documents Program. Even a buck fifty a month helps out.

Continuing to rough out some Heavy Lift Launch Vehicle CAD models. Instead of lumping them all together I’m breaking them into “genres,” partially because my computer is starting to balk at the the size of the full collection. Below is the “Solar Power Satellite Launchers” collection. Included, from left to right, Rockwell Star Raker, Boeing TSTO, Boeing “Big Onion” SSTO, Saturn V, NASA Personnel Launch System ( a Shuttle derived design), Boeing Space Freighter, NASA-JSC HLLV. There are a few more designs that could probably be added to this collection. Suggestions?

As previously indicated, there is a good chance of a 1/288 scale model of some of the designs such as the Saturn V and the Star Raker. But *all* of them? Probably not in that scale. What seems reasonable is something akin to the old Monogram “missile collection” kits, with all of the HLLVs in something like 1/500 or 1/700 scale. A similar collection of Nova/Post-Saturn boosters is possible.

The Space Freighter would be substantially impressive in 1/288… but really rather enormous.

The Shuttle-C of the late 80’s/early 90’s would have carried a whole lot more to orbit than the Shuttle Orbiter, but would not have been quite as capable of precise maneuvering as the Orbiter. Consequently, it might get close to a space station, but it would be unlikely to dock with it unless it was moved into position with secondary orbital maneuvering vehicles or grabbed with manipulator arms. This artwork depicts a Shuttle-C standing off some distance from a space station, with the cargo being shuttled over with an OMV.

The Shuttle-C was described and illustrated in US Launch Vehicle Projects #4.
