I am looking for the name of an Tupolev aircraft, build around 1935,
three seat, engine M-58 with 850hp, recon, lowwing, which i found in B
Arct
book 'All the worlds
aircraft 58'. A prototyp of ANT-51?
Any clue?

You are probably speaking about ANT-40.1 with Wright-Cyclone radial
engines - the first prototype of the later SB bomber. On the page
http://www.ctrl-c.liu.se/misc/ram/index.html you can find index of early
Russian (tsar epoch) and Soviet aircraft. The site seems to be updated for
the last time in July of 1999. There is no mention about M-58 engine so I
suspected a typo (there was ANT-35 from 1936 powered by M-85 engine, a
licence built Gnome-Rhone Mistral-Major 14Krsd). Other source ('Handbuch der
Luftfahrt Jahrgang 1939' by W. von Lanfsdorff, J.F. Lehmans Verlag) has a
short entry on 'MJ-13 (A.N.T. 40) 1934' where I found that M-58 were
watercooled 12-cyllinder V-motors which resembles rather Hispano-Suiza
12Yrds of the second prototype ANT-40.2. The site is relying mainly on a
two-volume book by V.B. Shavrov 'History of aircraft construction in the
USSR', ISBN 5-217-02528-X. I don't know who is right. I assume that Shavrov
is more credible in this area.
ANT-51 (the later Su-2 or BB-1) was designed by P.O. Sukhoy under general
supervision of A.N. Tupolev. The works started in 1937 and aircraft was
fitted with M-62 (later with M-87A) engines.

PS. Was it the book by Bohdan Arct? Do you read in Polish?
