Methods of simulating gas turbine transient behavior are reviewed. Two digital computer methods are described, one assuming instantaneous flow match and the other making use of intercomponent volumes to compute the rate of change of pressure at different locations. Results are shown for a variety of engines, good agreement between engine test and simulation being achieved in each case.
