Research on experimental testing method of motion characteristic parameters of projectile in bore

It is essential that accurate measurement of projectile in-bore kinematic parameters for the design optimization, performance and effectiveness evaluation of projectiles, especially for the optimization of the design of new artillery shell functional components to resist the high overload of launching and the evaluation of the overload resistance. Combined with the engineering practice of new type of artillery shell, based on the analysis of the launching environment of artillery and the motion characteristics of the projectile in the bore, this paper discusses the basic measurement conditions required by the relevant testing systems, and expounds the principles and characteristics of the main testing methods for the motion speed and rotation speed of the projectile in the bore and their corresponding acceleration and jitter posture. The research deficiencies and subsequent development in this field are summarized and prospected, and solutions are put forward for synchronous measurement of multi-parameters of projectile motion characteristics and the accurate and efficient processing of test data.
