Karadan Karaya Bir Merminin Burun Eyletim Kiti Kullanılarak Güdüm ve Denetimi

Abstract

Surface-to-surface projectiles are fired from ground launchers to specified ground targets to destroy them in an effective and economical manner. The mentioned munition is usually unguided and thus follows a ballistic trajectory. However, it is inevitable to have large miss distances when the diverting effects of the wind and thrust uncertainty are apparent. In this study, a gradual guidance and control strategy is proposed to improve the performance of this kind of munition. The effectiveness of this approach is shown by means of relevant computer simulations. The use of a simpler and cheaper nose actuation kit with pneumatic actuation makes this approach a preferable option for the application.

Performance Comparison of Guided Mortar Projectiles with Fixed and Moving Fins

“…In this extent, the guided projectiles seem to be viable candidates for air-to-surface applications. It is obvious that the success of such munitions is related to the performance characteristics of the chosen control approach [1,10]. The present examples to the air-tosurface guided projectiles can be given as in Figure 1, Figure 2, and Figure 3.…”

“…This way, it has become possible to attain the cost effectiveness and minimum colateral damage requirements apart from the high performance demand. In this context, guided munitions have been developed by regarding guidance and control algorithms designed as per certain technical specifications [1]. Actually, the guidance and control problem constitutes a wide area for the control of aerial platforms as well as munitions [2,3,4].…”

“…The second group involves the smart bombs built by mounting specifically designed guidance kits upon existing general purpose bombs. Actually, guided projectiles are involved in the latter class because they are the composition of the guidance kits with unguided projectiles [1].…”

“…Looking at the available guided projectiles around the world, it is seen that they are intended to be fired from launchers deployed on ground against prescribed stationary surface targets. In those munitions, one of the control strategies below is considered in order to reach the desired guidance and control effectiveness [1,5]:  Use of nose actuation kits. In the selection of the most convenient control approach, the first attempt is upon the establishing a convenient mathematical model for the projectile under consideration [6][7][8].…”

“…In the selection of the most convenient control approach, the first attempt is upon the establishing a convenient mathematical model for the projectile under consideration [6][7][8]. In this extent, one of the most significant considerations is the endurance of the relevant munition against the high acceleration loads occurring in firing through the launcher [1,[7][8][9][10]. Actually, this issue is more critical for the surface-to-surface guided projectiles than the air-to-surface configurations due to the effect of the booster resulting high amount of linear acceleration [11,12].…”
