Aeroelastic Problems of Low Aspect Ratio Wings: Part IV. Application of the Structural and Aerodynamic Matrices to the Solution of the Flutter Problem

To determine the flutter speed, it is customary to introduce all factors into the Lagrange equations with the flutter speed as one of the variables. This paper deals with the energies to be substituted, and the ways and means to solve the problem. There are two distinct approaches to the solution, one which is well suited for calculation on digital computors, and one which is convenient for solutions by way of analogue computors.
