The variable cycle engine switches working modes by way of changing variable-geometry components to achieve the dual advantages high unit thrust and low specific fuel consumption. Due lack a large amount rig test data complex modeling rotating components, incomplete characteristics lead non-convergence component-level model engine, which makes it difficult design follow-up control system. Aimin...
