NASP PR Card #1

In the days before the web came to domination, aerospace companies and government organizations would stamp out glossy propaganda/PR informational cards by the truckload. The X-30 NASP (National Aero Space Plane) program was no different. Below is one such card released by NASA. Note that first flight was expected by 2000 or so… just slightly behind schedule at this point. The design shown here is the final publicly revealed configuration, with the wide flat “spatula” nose. Not shown in this – or pretty much any – illustration are the rocket engines needed to put the spaceplane into a circular orbit.

NERVA nuclear rocket engine artwork

A NASA illustration of the NERVA nuclear rocket, dated December 1963. Near the top of the engine are two vernier rocket nozzles for thrust vector control.

If NERVA is a subject of interest to you, I have scheduled a trip to Washington D.C the last week of March for the express purpose of spending an entire business week in a NASA archive doing scanning and photocopying and photoing of as much as I can, starting with NERVA, moving to SPS and then to early shuttle concepts. I’ve visited this archive before, always for no more than a day, and that was only enough to show me that they had a lot, not enough to let me actually copy what they had. This time will be different. To help me pay for the trip (travel is *not* cheap these days), I am taking subscriptions or investors or whatever you want to call it. If you give me $100, when I return I will send you DVDs that will include all scans, and scans of all photocopies, and all photos taken at the archive. This offer is good up to the time I leave; once the trip is underway, it will be closed. If interested, either comment here or send me an email: scottlowtherAT up-ship.com

You can download a 13.4 megabyte JPG file of the illustration. The link to the JPG file is HERE. To access it, you will need to enter a username and password. These are available on the first page of the Aerospace Projects Review V3N2 Addendum (available HERE) Note that both are case sensitive.

Grumman shuttle/Saturn concept

From 1970, a Grumman Alternate Space Shuttle design that utilizes the S-IC booster from the Saturn V. Quite a number of Space Shuttle concepts called for the S-IC to be used as a first stage booster, as an expendable stage, a partially reusable or fully reusable stage. Shown here, the basic S-IC would be expendable. However, a second option would be to use a modified S-IC where the outer four engines would drop off during ascent and would be recovered. This is the same concept that Boeing proposed for the S-ID stage (see the October 2008 issue of the AIAA-Houston “Horizons” newsletter for more on the S-ID).

The use of a S-IC – stock or modified for partial recovery – would have presented a number of advantages, not least being that the existing Saturn launch facilities could be used. The S-IC would have provided adequate launch performance; the use of recoverable engines would have lowered cost and increased performance. However, the S-IC production line had been shut down for some time, and restarting it would have proven not only politically dubious (restating the S-IC would have led to questions about restarting the rest of the Saturn/Apollo line), but also expensive.

Early Convair Space Shuttle

In October of 1969, General Dynamics/Convair reported to NASA on their Space Shuttle design work. This included a series of vehicles that utilized boosters and orbiters of similar geometry… basically little more than flat-bottomed aeroshells wrapped around the oxygen and hydrogen tanks. Both the booster and orbiter used turbofans stowed in the nose for flyback, and high aspect ratio variable geometry wings.

A number of configurations were studied, including triamese configurations with two boosters that had considerable commonality with the orbiter, to two-stage systems with entirely different boosters and orbiters. Payloads studied ranged from 25,000 pounds to 50,000 pounds. Note in the scale drawings below that the 50K version was virtually the same size as the Saturn V. This was due in part to the all-hydrogen fuel, and part as a consequence of reusability.

North American Hypersonic Transport

Conceptual artwork from 1967 depicting a Mach 10 to Mach 14 hypersonic transport. Hydrogen burning scramjets would provide cruise propulsion at an altitude of 110,000 to 140,000 feet. No further data is available apart from what can be determined from the artwork. There are 136 seats, relatively few for an aircraft that is clearly quite large. The general configuration is similar to the hypersonic testbed previously posted HERE, especially the propulsion system & inlet arrangement.

Martin Dyna Soar Details

The 1959 Dyna Soar design from the Martin Company, designed by Hans Multhopp (formerly of Focke-Wulf). This was from when the Dyna Soar was a sub-orbital research vehicle meant to be lobbed by a modified Titan I ICBM. Note the inclusion of a turbojet engine for landing purposes, a common design element at this stage in the program.

Note that the cockpit of this little spaceplane was designed to be ejected in the event of an emergency. At this stage in the Dyna Soar program, the vehicle had lost its role as a bomber, and had been reduced to an R&D vehicle, thus the “cargo bay” stuffed full of equipment. Boeing’s final Dyna Soar design also had the instrument-filled cargo bay, but they fully expected to be able to ditch the instruments (which were mostly to measure and record pressure and temperature data all around the vehicle during re-entry) once the testing phase was over, and then proceed to fill the bay with useful payload, everything from anti-satellite hardware to passengers going to space stations.

The turbojet would very quickly be abandoned as weight climbed, meaning the Dyna Soar would glide to a landing much like the Space Shuttle.

A full-scale mockup of the cockpit was built… note that it appears to be made of cardboard. Cheesy, but perfectly adequate for preliminary layout purposes. Plus, some little kid may have gotten one hell of a spiffy Space Patrol Rocket to play in after its utility for Martin was finished. Note also the side-stick controller.

BAT in Hi-Rez

A publicity photo of the BAT (Bell Advanced Tiltrotor), a circa 1984 concept for a one-man attack tiltrotor to complete in the Army scout helicopter program (LHX – Light Helicopter Experimental) that led to the abortive RAH-66 Comanche. Shown here is a full-scale mockup; the prop-rotors as shown are substantially chopped down from the length they’d be on the actual aircraft. The BAT would have outperformed all other competitors except for hover performance; but the Army did not want a fixed-wing vehicle, so the BAT did not progress very far in the competition.

Early “Sea Launch” Concepts

Jan 262012

A Boy Scout booklet on making models (printed sometime in the 1980′s or later, but was originally printed in 1964) contained a number of rather tiny black and white futuristic automobile, ship, aircraft and spacecraft artists concepts. Sadly, there were no notations as to who created the artwork. Several of the pieces I recognize as having been created for Real Projects by Real Companies or Real Government Organizations, so I assume that at least most of the ones I *don’t* recognize were also “real” projects, as opposed to, say, artwork created for Mechanix Illustrated.

Three of the illustrations show large ships preparing to launch large missiles. These can be safely assumed to be space launch rockets rather than ICBMs.

The first illustration seems to show an Atlas launch vehicle being launched off the back of a large ship… apparently a modified aircraft carrier. The payload on the Atlas has an escape tower… indicating that it’s a manned Atlas (perhaps Mercury). Oddly, the ship seems to be underway to judge from the wake. This seems unlikely, unless it’s a tactic to keep up with the wind. Chances are fair that this might be a Convair concept.

The second concept shows a smaller ship and a smaller rocket. Perhaps a Scout?

The third concept shows another large ship, heavily modified with what look to be armored domes. The rocket appears to be an Atlas-Centaur.There appear to be propellant tanks amidships… perhaps liquid hydrogen tanks. Again, chances are fair that this is a Convair concept.
