Aiming at the problems of large mechanical stress and strong magnetic field when the electromagnetic coil ejector ejects large load, proposes a missile electromagnetic coil ejector scheme. Taking a certain type of missile as the target, the ejection system model is established for simulation analysis. The results show that this solution can increase the number of discharges of the driver coil, so that the ejector can accelerate the missile stably and with a small acceleration force at a short distance, and obtain a high initial velocity.
