Abstract:

An innovative technique was developed at the Armament Research and Development Center to produce software modules that implement piecewise analytical solutions to autopilot components for use in the flight simulations of smart munitions. This report extends the technique to the modeling of a two-axis gimballed gyroscope with nutation damping. The analytical approach eliminates the need for inordinately small integration time steps required for stable numerical integration resulting in a considerable saving in computer simulation time.
