Abstract : EMS, EQUATIONS OF MOTION, REAL TIME, COMPUTER PROGRAMSANALOG SIMULATION, CONTROL THEORYThe report describes an analog simulation of a generalized single-rotored helicopter rotor system as programmed on an EAI 231R-V analog computer. The simulation described is modeled from equations of motion of sufficient detail so as to permit the use of the simulation in flight control and avionics design studies. The program is suitable for use in a hybrid computer total forces and moments simulation or as a part of a more simplified analog computer model of a single rotored helicopter. An automatic setup and check program is described which allows rapid reconfiguration of the analog rotor program to represent many different kinds of rotor systems, including the hingeless and articulated types with any number of blades.
