I got the following e-mail by Aviatik which is clarifying the matter finally in favour of my speculation: *
FREIBIER!!!
Einstein's WWI Aviation work...
Hannes,
Would you be so kind as to forward this to theaerodrome for me. My
connection to it kept crashing, so I thought you would get the information
just as soon via email.
The article, "Herr Dr. Prof. Albert Who? Einstein the Aerodynamicist That's
Who! or Albert Einstein and His Role in German Aviation in WWI" was
published in the Peter Grosz "Archiv" column in WWI Aero Vol. 118 February
1988 issue. (Pgs. 42-46)
The article tells why he moved back to Berlin following his work in Prague
and Zurich. He came back after he was invited to become the titular
professor of physics to assume the post of director of theoretical physics
at the prestigious Kaiser Wilhelm Institute in 1914. The article tells of
his interest in aerofoils and some of his experiments. He apparently
published a study in 1916 on the elementary theory of water and waves and
flight. It is thought that Einstein probably felt he needed to earn his
consulting fees and wanted to make a contribution. It tells of his "cat's
back" aerofoil and also tells what type of aircraft it was fitted to, the
LVG D9v, which was the company designation of the LVG C.II. D9 was the
design name and the v meant "vorn" or "forward" designating the pilot's
position up front. Einstein thought he was onto something and wanted to
design an airfoil with maximum lift with minimum drag capability. The
article gives dimensions of a test aerofoil that was submitted and test at
Goettingen. It also shows a polar diagram of the profile measurements.
