Because of family committments we will be away between March 5th and April 23rd, 2020. We will still ship purchases, but there may be a delay. Please email us before ordering if you have any concerns about timing.

Frazer, R. A. & W. J. Duncan

The Flutter of Monoplanes, Biplanes and Tail Units

  • First edition of the sequel to The Flutter of Aeroplane Wings (1929), widely considered the “Bible of Flutter”. Scarce; WorldCat locates only nine institutional copies, and auction records include one copy sold at Dominic Winter in 2011.

    The term “flutter” refers to sustained oscillations of the structures of planes that can damage or destroy them. The first documented case occurred in 1916, affecting the tail of a Handley Page O/400 bomber, and by the 1920s flutter was a major area of aeronautics research.

    “At the NPL [National Physical Laboratory] work was initiated in 1925 by R. A. Frazer; he was joined in the following year by W. J. Duncan. Two years later, in August 1928, they published a monograph, ‘The Flutter of Aeroplane Wings’, R&M 1155. This slim volume, of just over 200 pages, has been known ever since as ‘The Flutter Bible’, and understandably so... it is quite astonishing in its completeness. Frazer and Duncan solved the flutter problem, in all its essentials, laying down the principles on which flutter investigations have been based ever since.” (Collar, “The First Fifty Years of Aeroelasticity”, Aerospace, February 1978, pp. 14-15).

    Frazer and Duncan’s research programme “made use of simplified wind tunnel models to identify and study phenomena, gave well-considered, cautiously detailed design recommendations, and indicated broad programs required for measurement of aerodynamic derivatives. They introduced an important concept of ‘semirigid modes’ which greatly simplifies the theoretical analysis... In effect this concept enables the problem to be handled by ordinary differential equations rather than by much less tractable partial differential equations” (Garrick & Reed, “Historical Development of Aircraft Flutter”, Journal of Aircraft vol. 18, no. 11, Nov. 1981, pp. 900-901).
