Bu çalışmada, ortalama 3 km irtifaya 4 kg yükü taşıyabilen katı yakıtlı bir model roketin farklı kanat modellemelerine göre uçuş analizleri sayısal olarak araştırılmıştır. Bu yük ve irtifaya göre roketin ve kanatların CAD modeli OpenRocket programında oluşturulmuştur. Programda mevcut uygulamalarda kullanılan delta, yamuk, kırpılmış delta, ok delta ve kırpılmış ok delta kanat modellerinin roketin hızında, stabilitesinde, ivmesinde, ağırlığında ve irtifasındaki değişimlere etkileri grafikler halinde sunulmuştur. Elde edilen sonuçlara göre, en iyi uçuş verileri ok delta kanat modelinde bulunmuştur. Daha sonra, bu kanat modeli referans alınarak yeni tip bir kanat modeli geliştirilmiş, bu kanat modeli çentikli delta kanat olarak isimlendirilmiş ve bu kanadın uçuş verileri analiz edilmiştir. Yeni kanat geometrisinin ok delta kanat geometrisine göre yaklaşık olarak roketin irtifasında %0.382, hızında %0.366, ivmesinde %5 artış meydana getirirken roket stabilitesinde %2.66, ağırlığında %0.287, basınç merkezinde %0.507 ve ağırlık merkezinde ise %0.568’lik bir azalma sağladığı görülmüştür. Bu sonuçlara göre, çentikli delta kanat modelinin roketin performansında olumlu etkiler sağladığı görülmüştür.
