Abstract
For anti-aircraft missiles to intercept the small size of the object in a small miss distance condition cited war with the problem, analyze the warhead to Fuze distance interception prejudice to such objectives, through theory and simulation analysis, the distance is small miss distance to intercept small size of the target with the effect of the lead battle influence evident in the actual engineering design, we need to consider the impact of the distance to lead the war with the design of the proposed boundary distance constraints.
Highlights
From the lead battle with the effects of simulation map view, without considering the distance fuze to warhead, fuze average starting position at 1m off target amount condition lags Warhead dynamic scattering area, that broken pieces scattering area can not cover the target key points, features point lead with ineffective war, after analysis of the optimal delay models, that the main reason is the distance to the warhead fuze impact on the battle with the effects of lead
For formula 1, in the best delay is not less than zero conditions, in order to ensure fuze average starting position is not lagging behind the fragmentation dynamic scattering area at this time, when the miss distance tends to 0( L = 0), the presence of the following formula : lim [ 0
Best Start Delay Fuze engineering calculation model, the distance to the warhead fuze fuze trigger delay mainly affects the calculation has no impact on fragments flying time, the inherent delay and off target azimuth correction time, consider the following fuze to fight the influence of the distance portion of the original model to improve the trigger delay
Summary
Past air defense missile guidance deviation is bigger, in the design and analysis of fuze-warhead coordination, warhead and fuze is overlap, this assumption in the miss distance is reasonable, is largely due to the fuze trigger delay time of flight ( tf ) greater than the fragment ( tv 0 , flying fragment to a point of time) with the inherent delay fuze and (2#) Figure 1 does not consider the conditions lead to the warhead a distance of 1 # and 2 # ballistic cited war with renderings
