The invention relates to the field of aero-engines, in particular to a surge elimination control method for an aero-engine. The method comprises the steps: cutting of oil supply of a main combustion chamber, and quitting surge elimination; designing ignition oil supply control , wherein the engine is successfully ignited; and stopping ignition oil supply, switching oil-gas ratio open-loop oil supply, and recovering the state corresponding to the accelerator. The method has the technical effect of effectively eliminating surge in the slow vehicle state and the state below the slow vehicle state. 本申请涉及航空发动机领域，具体包括一种航空发动机消喘控制方法，包括，切断主燃烧室供油，退出消喘；设计点火供油控制，使发动机点火成功；退出点火供油，切换至油气比开环供油，恢复到油门对应状态。具有能够对慢车及慢车以下状态进行有效消喘的技术效果。
