The complete rework of APR from the original release a decade ago is going a lot slower than I’d planned. A lot of people have asked for the original versions of the as-yet-unreleased issues of APR to be made available. I’ve been hesitant to do so, but… it’s just taking too long. So, I’ve taken the original Word files for the six issues of Volume 4 and the six issues of Volume 5, and made two PDF files from them. I’m making them temporarily available as two bulk sets. When the issues are re-released, these full-volume sets will be withdrawn. So, Volume 5 might remain available till the sun explodes, I dunno…

If you’re dying to get hold of the old-school APRs, here’s your chance. Remember, these are the *original* files from around 2002-2004, without any updates, edits or other changes. Errors, crappy formatting and all. A bunch of the individual old articles remain available as well.

A recent series of patents has received some press, where some people suspect that this VTOL aircraft concept is a “flying car” from Google. The company is “Zee.Aero,” the inventor is Ilan Kroo, aeronautics professor on leave from Stanford.

The design features a multitude of small vertical lift fans and two forward thrust props. The vertical lift fans are each provided with an electric motor. The power would seem to be provided by a gas motor/electric hybrid system.

The system would seem to be fairly draggy, so it’s probably not intended for high speed. One of the patent illustrations shows one parked with folded wings in a conventional parking lot between two automobiles, indicating that there is some thinking that the inventors want this to be used as a “flying car,” It really doesn’t look roadable, so you’d have to land it at the destination. I shudder to imagine what would happen to one of these if left in a packed Wal Mart or Best Buy lot on Black Friday…

A black-and-white copy of a Bell Aerospace design for the Tri-Service (USAF, Army, Navy) VTOL competition circa 1962. Very nearly the Bell X-22… just a bit more refinement needed. Similar early X-22 artwork HERE and HERE.

An interesting design for a roadable aircraft:

autogyrol

See more & bigger drawings of this vehicle HERE.

For operations on the ground, it appears that the nose wheel (or nose treads, for off-road use) would be powered, while the prop would continue to provide thrust. Given Russian experience with aerosani, this is hardly surprising.

The idea of a roadable autogyro is neither new nor particularly silly. One such vehicle, the Pitcairn AC-35, was tooling around the streets of Washington, D.C. in the 1930’s:

And, perhaps vastly more interestingly, a new roadable autogyro, the PAL-V, may soon be tooling around the streets of the less-overly-regulated parts of the world soon.

At last: issue V3N3 of APR is now available. The first article covers the proposed use of bombers, specifically the B-52 and B-70, as launch platforms for the Dyna Soar manned military spaceplane.

v3n3dynabomberad2

v3n3dynabomberad1

The second article is on the Martin Astrorocket, a series of early-sixties design studies of reusable low-cost manned launch systems for the USAF.

v3n3astrorocketad

The next article covers the development of the Douglas XC-132 turboprop transport/tanker plane throughout much of the 1950’s. This would have been by far the biggest turboprop plane the us would have built… had it been built. Article contains a number of good photos of the full-scale mockup.

v3n3c-132ad3

v3n3c-132ad2

v3n3c-132ad1

Next is an article on the A-12 Avenger II stealthy strike plane for the US Navy. This article includes info and drawings on the Northrop competitor, as well as a number of rarely seen and all-new detailed diagrams of the A-12.

v3n3a-12ad2

v3n3a-12ad1

A brief article on a trio of Grumman designs from the 1989-1993 time period, VTOL lift-fan combat aircraft, including the Future Attack Air Vehicle (FAAV).

v3n3grumad

Last but not least, an article describing a trio of seemingly unrelated – yet possibly related – designs: a “landing boat” for Project Orion, a lifting body design for the Apollo program, and a fighter jet designed to be launched via booster rockets. Included is information on the logistics Landing Vehicle, General Dynamics’ equivalent of the Douglas ICARUS/Ithacus troop transport rocket.

v3n4llvad

And two “Aerospace History Nuggets,” a Ryan concept for a VTOL jetliner and a concept from Bell for linking two helicopters together to forma single heavy lifter.

v3n3nuggetad

Here’s the complete issue V3N3 layout:

A 1959 Bell Aerospace design for a Tri Service (Army, Marines, USAF) VTOL troop transport using vectorable ducted fans. This obviously led to the X-22 design. The fuselage was much like that of transport helicopters like the Chinook, boxy and unaerodynamic, but the propulsion system would provide considerably higher forward velocity.

A chart of Bell VTOL designs is HERE.

A photo of the Bell Helicopter BAT (Bell Advanced Tiltrotor) mockup built in the late 1980s. This was an early competitor in the Light Helicopter eXperimental (LHX) program, eventually won by what would become the RAH-66 Comanche. While the BAT met the early requirements of the program, it was too unconventional.
