The coil-type electromagnetic launch technology has the remarkable characteristics of non-contact, fast launching speed, large kinetic energy, excellent controllability, high energy conversion efficiency, etc., and it is an important part of the development program of future weapon systems. This paper describes in detail the principle of coil-type electromagnetic launch technology and summarizes the main research progress in this field in recent years. The key technologies of coil-type electromagnetic launch and their development are summarized from six aspects, namely, energy storage technology, electric energy regulation technology, coil and projectile design, trigger position control, power suppression of the throwing mechanism and field coupling research, and the research history is sorted out, and the trend of the application of the coil-type electromagnetic launch technology in the field of military, civil and aerospace is also prospected. It aims to provide certain reference and guidance for the subsequent research of coil-type electromagnetic emission technology at home and abroad.
