June 2018 APR Patreon Rewards

In just under the wire for June, 2018 are the rewards for APR Patreon patrons. Included this month:

• A sizable January, 1945 technical description of the YP-80 “Shooting Star” by Lockheed. 300 or so pages, filled with illustrations of the aircraft and components.
• “On The Utility of the Moon in Space Transportation: the Lunatron Concept.” A 1963 NASA concept for using an electromagnetic accelerator to hurl payloads from the lunar surface onto high energy trajectories, up to solar system escape.
• A scan of a large-format Sikorsky lithograph of an ABC (advancing blade concept) VTOL airliner (basically a 727 fuselage turned into a high-speed helicopter).
• An all-new CAD diagram of the Soviet Chelomei LKS spaceplane with an inboard profile showing the military (nuclear bombardment) payload. The first in a series on the LKS.

If you are interested in helping to preserve (and get copies of) this sort of thing, consider signing up for the APR Patreon.
