摘　　要：自适应循环发动机作为里程碑式变循环构型引入诸多新颖部件而实现“大幅度变循环特征”设计宗旨,可适应更宽速域和更广空域以满足未来飞行器更为苛刻的性能需求,但这也导致其不同工况可调参数控制规律更加复杂。本文以简化改善自适应循环发动机控制规律设计为目的,基于建立自适应循环发动机性能模型,对比分析典型工况不同工作模式性能差异,给出地面、亚声及超声巡航模式使用方案。本研究可提供典型工况模式选取依据,明确不同模式可调几何约束,促使自适应循环发动机控制参数大范围寻优难题分层拆解为工作模式选取及可调参数优化。As an evolutional concept of variable cycle engine,the adaptive cycle engine drives more components with novel technical characteristics to realize the “widely variable cycle characteristic”design purpose.It can fit the wider flight velocity and height range to deal with the more demanding future aircraft performance requirements.But these characteristics lead to further complexity of control schedules in different working conditions.To simplify the adaptive cycle engine control schedule design,we constructed the performance model,and analyzed the performance difference at various operating modes in typical flight mission profile.This study can divide the adaptive cycle engine control schedule large-scale optimization problems into the operating modes selection and variable geometry schedule optimization.
