technical field [0001] The invention relates to the field of bullets, in particular to an ISIGHT software-based full trajectory optimization design method for projectiles. Background technique [0002] The projectile design process involves internal ballistics, structural mechanics, aerodynamics, flight mechanics, terminal ballistics and other disciplines. The entire ballistic process is a complex process formed by the interaction of many parameters, and each ballistic segment is closely related. , the change of any parameter may have a great impact on the bullet system and even the entire weapon system. [0003] In the prior art, the design of the projectile is usually aimed at the design and optimization of the internal process of a specific ballistic segment, such as the internal ballistic process, the external ballistic process and the aerodynamic process, etc., ignoring the interaction and influence between the various ballistic segments.

Problems solved by technology

[0003] In the prior art, the design of the projectile is usually aimed at the design and optimization of the internal process of a specific ballistic segment, such as the internal ballistic process, the external ballistic process and the aerodynamic process, etc., ignoring the interaction and influence between the various ballistic segments. When the current parameters of the projectile reach the optimum in a certain ballistic section, it may not meet the design requirements in the rest of the ballistic section. Therefore, only studying a certain ballistic section alone cannot truly reflect the ballistic process of the weapon system, and it is difficult to achieve system optimization.

[0004] The development of optimization theory and methods provides a practical and convenient way for the design of projectiles when the full trajectory is optimal, so that designers can comprehensively consider various contradictions from a more macroscopic point of view and design the optimal scheme of the system; However, there is no related full optimization design analysis method disclosed in the prior art
