Book excerpt: The literature relating to vehicle stability was searched for papers in which flow separation from aerodynamic surfaces is explicitly studied. Data were found usually to deal with Magnus forces and moments, roll-yaw coupling, roll lock-in, and similar phenomena of less than obvious origins. Ample justification for detailed examination of boundary layers and of nonlinear equations of motion is offered by these examples since these are vehicle characteristics which are at present unpredictable primarily because three-dimensional boundary layer behavior is not well understood. Some examples of methods of numerical analysis of flight test data which aim at the extraction of the nonlinear coefficients of the equations of motion are cited. Finally, a background of well-established boundary layer theory is presented, and the advances of the past few years are reviewed. (Author).
