Abstract

Bu yayında namlulu silahların iç balistik prosesi tanımlanmıştır. İç balistik hesaplamalarına ilişkin matematik model oluşturulmuştur. Model oluşturulurken barut tane geometrisine bağlı olarak geliştirilen biçim fonksiyonu kullanılmıştır.  Modelin MATLAB ® programında kodu hazırlanmıştır. Modelin doğrulanmasında, literatürden temin edilen 40 mm silah sisteminin atış sonuçları kullanılmıştır. Söz konusu atışta kullanılan silah ve mermi parametreleri kodun çözümünde kullanılmıştır. Kodun çözümü ile atış sonuçları kıyaslanmıştır. Mermi çıkış hızı ve namlu içerisindeki maksimum basınç parametreleri açılarından yapılan kıyaslama sonucunda standart sapmanın %4 seviyesinde olduğu tespit edilmiştir. Böylelikle matematik modelin doğrulandığı sonucuna varılmıştır. Bu model kullanılarak silindirik, tek delikli silindirik ve küresel barut tanelerinin iç balistik performansına etkileri incelenmiştir.

Abstract

The description of interior ballistics of guns are given in the paper. The mathematical model is developed for interior ballistic calculation. During the mathematical model development process geometrical properties of propellant are used as the form function. The code of the mathematical model is written in MATLAB ®. 40 mm gun firing results which got from the literature were used in the model verification process. The code solved with the parameters described in the experimental study. Results of the mathematical modal are compared with the firing results. The results showed that the standard deviation of muzzle velocity and maximum pressure in the barrel was less than 4%. Therefore the modal were verified. After verification process cylindrical, single perforated cylindrical and spherical granule shapes’ effects on interior ballistics were inspected with the modal.
