Dec 312020

Just released, the December 2020 rewards for APR Patrons and Subscribers. Included this month:

Diagram: a large format diagram of a Lockheed cruise missile. The designation of the missile is not given, but this looks like a SCAD design.

Document 1: Consolidated Class VB Carrier Based Bomber, from 1946

Document2: “Economic Aspects of a Reusable Single Stage To Orbit Vehicle,” a paper by Phil Bono on the ROOST launch vehicle from 1963

Document 3: “Shuttle Derived Vehicles,” a NASA-MSFC briefing to General Abrahamson from 1984

CAD Diagram: XSM-64A Navaho, the configuration that would have been built as an operational vehicle had the program gone forward

Possibilities of New Business Growth: ICBMs

nukes, rockets No Responses »

Dec 242020

In 1985, Rockwell International considered the possibility that there might be profit in ICBMs. In particular, small ICBMs (“Midgetman”), road-mobile with a single warhead. Sadly, the SICBM did not come to be. Nor did any other ICBM. The current ICBM that the USAF fields is the Minuteman, merely an updated version of the same missile first fielded nearly *sixty* years ago. The Peacekeeper ICBM was deployed the year after Rockwell produced this document… and the Peacekeeper was withdrawn twenty years later with no replacement in sight

“Future Starships”

nukes, rockets, spacecraft No Responses »

Aug 312020

Late 1970’s depictions of “realistic” starships as understood at the time. These include an Orion vehicle (which, despite claims to the contrary, would make a terrible starship, since the specific impulse of a reasonably conceivable Orion is an order of magnitude or two too low for practical interstellar craft), two Bussard ramjets, and a “golden globe” minimum weight starship proposed by Robert L. Forward, whose operating principles I am currently a bit fuzzy on.

Bussard ramjets would use magnetic fields to collect interstellar hydrogen. The hydrogen would be compressed in a fusion reactor, preferably a steady-state one, and used to provide thrust to the starship. For a number of years this concept promised great things, but in recent decades it has been pretty much discounted. On one hand, the magnetic fields are not very likely going to work well at a reasonable mass, and they tend to not form open-mouthed funnels, but rather closed-mouthed “cups,” thus preventing the hydrogen from getting into the engine. Whoops. Second, thrust is unlikely to exceed drag much above maybe a percent or two of lightspeed, meaning a Bussard ramjet might serve as a decent “anchor” or drag brake, but not as an accelerator to relativistic velocities.

Recent eBay procurements

Aug 132020

One of the main purposes of the Monthly Historical Documents Program/APR Patreon is to get rare aerospace items from eBay. These items are then made available to subscribers/patrons via monthly votes and catalogs.

Below are some of the items I’ve recently paid for (though not as yet received). If you are interested in getting high-rez scans and/or helping me save these sort of things for future generations (as well as keeping my cats in food and litter), please consider signing up for the Monthly Historical Documents Program or the APR Patreon.

MX-2276 BoMi

Jun 262020

Before the Convair Atlas ICBM proved that it was possible for a rocket to reach out across the world and deposit some canned sunlight reliably close to commie targets, it was understood that the only way to accomplish the task was with pilots and bombardiers. But by the mid 1950’s the idea of subsonic manned bombers sneaking into the heart of the Soviet Union without getting swatted was starting to seem nonsensical. So Bell Aircraft, under the direction of former V-2 program director Walter Dornberger, dreamed up the MX-2276: a three-stage manned rocket bomber. Looking akin to an evolved Sanger Antipodal Bomber, the MX-2276 used two manned and winged stages, with an unmanned expendable stage in between. The final stage would carry a single gliding nuclear warhead deep into the USSR, using the human crew to attain some measure of accuracy.

But then the Atlas came along and ruined all that.

The idea persisted, however, turning first into the Bomber Missile (BoMi) then the Rocket Bomber (RoBo) then Dyna Soar. With each step it became less fantastical, and also less of a dedicated weapon system; by the end of the Dyna Soar, it was a one-man experimental re-entry vehicle launched by a fully expendable Titan IIIC. Since then the idea of a “rocket bomber” has popped up from time to time, but never with the level of seriousness displayed in the mid/late 1950’s. For more on the whole BoMi program, see Aerospace projects Review issues V2N2, V2N3 and V2N4. APR issue V3N4 gives a pretty complete rundown of the final Model 2050E Dyna Soar.

Hughes Orion

Apr 172020

A piece of art from Hughes Research Labs from the late 70’s depicting an Orion nuclear pulse vehicle in flight. Sadly low rez, but whatareyagonnado.

It’s an interesting piece, but it seems likely to be quite inaccurate. in deep space when the system operates in a pretty hard vacuum, the fireballs resulting from each blast would expand outwards at a speed of many hundreds or thousands of kilometers per second.
