Numerical Simulation of Engine Inlet Hood Separation

According to the normal working process of launching a certain type of aviation weapon, the engine inlet hood is first separated normally, the engine is then ignited and started, and then the weapon enters the autonomous flight phase. Tt is necessary to analyze the motion characteristics of the inlet hood during the separation process. This paper constructs a research on the safe separation technology of inlet hood based on simulation prediction. The risk that can be released in advance can be completely and comprehensively removed through numerical simulation prediction and wind tunnel test, so as to verify that this type of inlet hood can be safely separated and ensure the safety of the test.
