This report describes a rotorcraft nonlinear simulation called REXOR, and is divided into three volumes. The first volume is a development of rotorcraft mechanics and aerodynamics. The second is a development and explanation of the computer code required to implement the equations of motion. The third volume is a user's manual, and contains a description of code input/output as well as operating instructions. The REXOR math model has been written for a single four-bladed, gyro-controlled, hingeless-rotor helicopter with additional capability for analysis of teeter or hinge-offset rotor systems with conventional controls and two or four blades. The helicopter modeled may be conventional in design, winged or compounded. Modeling emphasis is on an accurate main rotor description with additional degrees of freedom to describe the rest of the helicopter. REXOR has been implemented on IBM 360 and CDC 6000 series equipment. The operating instructions are primarily based on the 360 equipment usage with additional instructions to show use on the 6000 series equipment. (Author)
