A report by the British Intelligence Objectives Sub-Committee (BIOS); October 1945
A report (by the US Naval Technical Mission in Europe, distributed by BIOS) of developments on aircraft vibration and flutter research by some of the most important aircraft design groups and research centres in Germany
Duplicated typewritten report in English, 10 x 7.5 inches, 25 x 19 cms. 69 pages, 20 illustrations.
Very good in original stapled card wrappers.
The elimination of flutter, the dangerous oscillation of aircraft wings or other parts, caused by the interaction of aerodynamic forces, structural elastic reactions, and inertia, had become increasingly important in aircraft design.
The phenomenon had been known since the early days of aviation. However, the rapidly increasing speeds of aircraft in the late 1930s and 1940s had resulted in a higher likelihood of flutter occurring.
This could, and indeed did on several occasions, lead to the complete break-up of the aircraft in flight.
The military-led research from the 1930s onwards into the problems of flutter, including the work covered in this report, resulted in the safe design of modern civilian passenger aircraft.
A major work, rarely seen for sale.
