The lateral impulses, functioning as a correction mechanism, is subject to work parameter errors resulting from variations in product batches and storage conditions, which directly impact its striking accuracy. This study systematically measures the engine""s impulse, thrust, and operating time through static and dynamic tests, while also examining the effects of assembly errors, particularly radial eccentricity.Static test results indicate that radial eccentricity causes the thrust direction to deviate from the ideal ballistics, significantly reducing the accuracy of the work parameters. Dynamic tests confirm the continuous ignition characteristics under rotating projectile conditions, illustrating the substantial influence of pulse force on rotational speed.Ballistic simulation analysis further reveals that both radial eccentricity and thrust errors markedly diminish correction accuracy, adversely affecting the distribution characteristics of ballistic impact points. By integrating experimental and simulation findings, this research investigates the sensitivity of various work parameter errors to final impact point precision, providing essential data to optimize the design of pulse correction mechanisms. This work establishes a foundation for enhancing smart munitions control capabilities and advancing research in related fields.
