NASA PDF - NACA reprint of 1934 Eugen Sanger rocket plane paper

NACA 1942 reprint of a 1934 Eugen Sanger rocket plane paper:


Recent results in rocket flight technique - December 1934
Sanger, Eugen
NASA Center for AeroSpace Information (CASI)
NACA-TM-1012 , 19420401
The concept of the effective ejection velocity of a rocket engine is
explained and the magnitude of the attainable ejection velocity
theoretically and experimentally investigated. Velocities above 3000
meters per second (6700 mph) are actually measured and the
possibilities of further increases shown.

Does NASA have Sanger's wartime "Rocket Drive for Long Range Bombers"
report online by any chance?
His rocket motor design for the Antipodal Bomber is really fascinating,
as its propellant feed system consists of a steam-driven turbine that is
bootstrapped into the combustion chamber/engine bell cooling system.

In his "Interplanetary Flight" (1947) Arthur Clarke notes that Sanger's
report was "restricted, until very recently, despite the fact that the
British, Americans, French and Russians each possess a copy. One wonders
just who was keeping it secret from whom".

Doing a search by author, there are a few articles by Eugen Sanger,
but not that one.

"A Rocket Drive for Long Range Bombers" was translated and published
by the Navy. Translation CGD-32, Technical Information Branch, BUAER
Navy Department. It was reprinted and sold - I got a copy in the late
60's(?).
The first page on my copy is titled A Note by the Publisher, and
shows at the bottom of the page:
Robert Cornog
Santa Barbara, California
16 November 1952

A copy like this went for a pretty penny on Ebay several weeks ago.

And a copy can be had for pennies if one has a library card and a nearby
photocopier. That's how I got *mine*.

I've read it; I got a copy of it on interlibrary loan from
Wright-Patterson AFB.
It's an interesting and very forward looking report; however the chances
that Germany could have gotten it working during the war are nil. It
would have been difficult to get a horizontal sled launched
transatmospheric vehicle working by 1965, much less 1945.
One very interesting thing in the report is Sanger's computations on
what would happen with bombs hitting a target while traveling at
hypersonic horizontal speeds.
According to him, the area of blast damage would take on an odd teardrop
shape with the impact point being at the point of the teardrop, due to
the fact that the explosives creating the blast would be traveling
sideways at a higher rate than the expansion rate of the gases generated
by their detonation.
Then there's the pictures of shooting the rifle bullet around the
circular trough lubricated with grease to see how to build the launch track.
The Antipodal Bomber project got nowhere near the money or effort thrown
at it that the V-1 and V-2 did, although there is a surviving photo of a
mysterious "something" at Lofer that could possibly be the nose of an
Antipodal Bomber mock-up:

They really should do a pdf of that one- that's where the whole Bomi,
Robo, Brass Bell, and Dyna-Soar concepts get started at.
And that horizontal launch track concept still keeps coming up, right up
till the present day.

In case anyone's wondering, his drawing is accurate; the Antipodal
Bomber was indeed designed as a tail-dragger, although most modern
drawings show it with nose gear.
