On the Aeroelastic Characterisrics for the Flight Vehicle of Wing-Body Combination

익동체(翼胴體)의 공력탄성학적특성(空力彈性學的特性)에 관한 연구(硏究)

This paper shows the method for obtaining the body flutter velocity and frequency for flight body which consists of low aspect ratio wing and body combination by assuming slender body of cylinderical shell structure. The stiffness matrix of the cylinderical shell is represented from Donnel eq. by the finite difference method, and also unsteady aerodynamic influence matrix is represented by the Doublet Lattice Method of Albano & Rodden. The flutter matrix can be obtained from those matrices.
