Highly important paper on computer aided numerical analysis of flight conditions, with over 50 words, 2 signatures, and 3 scientific illustrations in Gagarin's hand. Ironically written about aircraft which, 2 months after this was written, would cause his demise.
Carbon Typewritten Manuscript Signed with numerous crossouts and additions in ink signed, "Gagarin", and Autograph Note Signed in ink, "Gagarin", in Russian, 2 pages, separate sheets, 7.25" X 10.75", on verso of each sheet are diagrams in his hand, January 24, 1968, [Russia]. Light soiling and toning, fine condition.

Manuscript reads in part: "...Computer aided numerical analysis. 2. Experimental research in wind tunnels...An aerodynamic design of an aircraft was chosen and its aerodynamics (is) analyzed...according to Zhukovsky theorem, 'the smaller' holds the distributed load, which affects the wing...the results of theoretical calculations made on a BESM-2M electronic computer are shown on the diagrams...to be able to evaluate the landing dynamics of an aircraft, its flying properties, knowledge of the static performance alone is not enough...data for the damping moment by angular velocity and by shifting the center of gravity of the aircraft can serve as an example...Gagarin 24.1.68...Autograph Note Signed at the bottom of page 2, reads, "Irina, please leave empty spaces--approximately 10 cm each--for the diagrams in the text paper, where marked, and the rest is without change. Gagarin"

In 1968, Gagarin was studying at the Zhukowski Military Academy. This paper was work he was doing regarding computer aided analysis which he hoped would bring the Soviets to the moon. Ironically, the allegorical comments about flight rested on aircraft, wind, and flight angle of attack, which would cause his death in a flight training mission on March 27, 1968, two months after writing this. Non-souvenir material of Gagarin in the market is extremely rare. The "Columbus Letter" he wrote after his first flight sold for $354,500 at Sotheby's. A paper (one page) not as technical and without drawings sold for nearly $50,000 (Lot 33, 1993 sale). A once in a lifetime opportunity to acquire something important by Gagarin.
