The “Mach Buster” was an unfinished amateur-built prop plane that was optimistically planned (in the late 1980’s) to exceed the speed of sound. Sadly, I’ve long since lost the reference for where the below image came from, existing in my collection solely as a single photocopy.
A brief article on the Mach Buster was in the August, 1989, issue of Popular Mechanics.
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.
The heyday of the “atomic powered airplane” was the late 50’s-early 60’s. By the mid ’60’s it was done. But there was a brief, kinda sad and halfhearted revival in the seventies when the price of fuel spiked. An atomic airplane would be able to fly without all that pesky and overpriced petroleum; it could fly without producing pollution; and it could fly really, really far. Whether it could fly without irradiating the passengers, and whether it could fly at all, are questions largely left unanswered. The art below depicts a Lockheed concept for an atomic jetliner. It has the wasp-waisted configuration favored in the ’70’s for transonic jetliner designs, but where the reactor was supposed to go is not clear. *Presumably* it was to be fitted in the fuselage under the wings, as that’s the only place where no passenger windows are visible.
From the mid 1960’s, a Bell illustration of a 12-ton (presumably referring to payload weight) cargo or military transport hovercraft derived from the “SK-9” design.
From April 1959. Boeing won the competition to build the Dyna Soar with a desing that looked a lot *unlike* the Dyna Soar they actually started building; ironically, Martins design from December 1958 (working with Bell Aircraft) was far closer to the final Dyna Soar in configuration.
A design from 1963 that used four Bristol-Siddeley vectored-thrust Pegasus engines (same as used by the Harrier) and ten lift jets to give an otherwise fairly conventional cargo transport jet aircraft VTOL capability.
A circa 1957 Hiller quadcopter apparently designed for military roles. The cockpit seems to seat two side-by-side, with a twin-gun emplacement underneath. Other than that, not much can be determined from this piece of art.
A 1957 design for a flying crane quadcopter from Hiller.
Once again Patreon seems to be becoming unstable. So I’ve got an alternate: The APR Monthly Historical Documents Program
For some years I have been operating the “Aerospace Projects Review Patreon” which provides monthly rewards in the form of high resolution scans of vintage aerospace diagrams, art and documents. This has worked pretty well, but it seems that perhaps some people might prefer to sign on more directly. Fortunately, PayPal provides the option not only for one-time purchases but also monthly subscriptions. By subscribing using the drop-down menu below, you will receive the same benefits as APR Patrons, but without going through Patreon itself.
A beautiful illustration of a circa 1972 concept for a McD Expendable Second Stage for the then-planned manned flyback booster for the Space Shuttle. The Saturn S-IVB-derived stage would be equipped with an array of solid rocket boosters for maximum thrust and maximum complicatedness.
