Studies show that different geometries of a Variable Cycle Engine (VCE) can be adjusted during the transient stage engine operation to improve performance. However, this improvement increases complexity acceleration and deceleration control schedule. In order resolve problem, Transient-state Reverse Method (TRM) is established in present study based on Steady-state (SRM) Virtual Power Extraction (VPEM). The state factors component-based performance models are replaced by variable geometry...
