"The investigation was concerned with the development of a complete digital computer simulation of a single articulated rotor helicopter. The simulation program was executed on an IBM model 360-50 digital computer.
The main rotor was analyzed by the consideration of a continuous rigid blade at six azimuth stations, while the airframe aerodynamics were treated in the conventional manner. The differential equations of motion of the airframe were solved in a step-wise fashion by approximating time dependent functions with cubic interpolation polynomials.
The study concluded that there was strong evidence that suggested the possibility of treating main rotor flapping as a steady state phenomenon in helicopter simulation. In addition, it was concluded that digital step time may be extended to 200 milliseconds without impairing the quality of the model"--Abstract, page ii.
