This thesis investigates linear state space modeling of single main rotor helicopters culminating in a computer program that can be used for 1 stability and control analysis for any single main rotor helicopter or 2 preliminary design of a helicopter. The trim solution for a flight condition is found, the aircraft is perturbed about the nominal point, and the stability and control derivatives are determined. State space models and analysis tools are provided by the program. A notional attack helicopter designed for the 1993 American Helicopter Society Design Competition and a notional utility helicopter are used as examples.
