Sabit ve Hareketli Kanatlar ile Güdümlü Havan Mermilerinin Performans Karşılaştırması

Öz

Gelişen ve değişen savunma konsepti kapsamında, güdümlü mühimmatlar, yüksek başarım ve düşük tali hasar özellikleri dolayısıyla son yıllarda oldukça popüler bir araştırma alanı haline gelmiş olup bu konuda birçok teorik ve uygulamalı çalışma yapılmıştır. Bilhassa küçük ve hafif güdümlü mühimmat kullanımı, etkinlikten taviz vermeksizin bahsedilen üstünlüklerin elde edilmesini olanaklı kılmaktadır. Bu çalışmada, hava platformlarından atıldığı varsayılan havan mermilerini güdümlü hale getirmek amacıyla kullanılan bir güdüm kitinin tasarımı ele alınmakta ve belirtilen çerçevede gerçekleştirilen bilgisayar benzetimlerinin sonuçları sunulmaktadır. Bu kapsamda, güdüm kiti üzerindeki dönel halkaya bütünlenen bir çift kanatçığın serbestlik derecesine bağlı olarak iki farklı konfigürasyon üzerinde durulmaktadır. Güdümlü havan mermisinin düşük seyir hızlı bir insansız hava aracından bırakılması durumunu göz önüne alan bilgisayar benzetimlerinde, kanatçık açısı, otopilot anahtarlama süresi ve yan rüzgâr parametrelerinin farklı değerleri, bahis konusu konfigürasyonların her ikisi için de uygulanmaktadır. Çalışmanın sonunda, nihai hedeften sapma miktarı ve uçuş süresi değerleri, oluşturulan eşleşme koşullarının tamamı için hesaplanarak karşılaştırılmaktadır.

Performance Comparison of Guided Mortar Projectiles with Fixed and Moving Fins

Öz

Guidance munition has become one of the popular subjects in both the theoretical and applicable studies since they could find a wide field of use in recent years because of their high performance and lower collateral damage capabilities as per the improving defence concept. The use of smaller and lighter guided munition makes the stated advantages increase without relinquishing the effectiveness. In this study, the design of a guidance kit which makes the mortar projectiles become guided when released from aerial platforms and the relevant computer simulations performed upon a selected projectile model are investigated. Here, two different configurations are considered based on the rotational degree of freedom of a pair of fins mounted on a rotary ring. In the simulations in which it is assumed that the guided projectile is released from an unmanned aerial vehicle, the different values of the fin deflection, autopilot switching duration, and side wind are considered for both of the mentioned geometries. Finally, the final miss distance and time of flight values obtained for all the designated cases are compared.
