The Present Status of Aircraft Stability Problems in the Aeroelastic Domain

Abstract

In his classic paper, The Expanding Domain of Aeroelasticity, Collar indicated how various types of problems (involving at least two of the three kinds of force—aerodynamic, elastic and inertial), which had hitherto been dealt with in their own “watertight compartments,” were tending to coalesce into a single subject which might be defined as “the dynamics of a deformable aeroplane.” The title of the subject, as Collar pointed out, at once suggests (to the mathematician at least) the formal solution of the problems which it comprises.
