Abstract

In this work, a novel and national digital flow modelling capability has been developed as a further developing cluster for FLOWER Digital Modelling. With the developed model, in order to determine fast-variying flight stability borders and developing flight control softwares, related to flight dynamics and aero-dymanics, eddification of the daraught on an air vehicle during fast-varying wing and tail position changes has been estimated on designing body and wing of high manoeuvre-capable fixed-wing air vehicles.

Özet

Bu çalışmada yüksek hızlı, yüksek manevra kabiliyetine sahip sabit-kanat hava araçlarının gövde ve kanat tasarımı gerçekleştirilirken zamanla-hızlı-değişen (ZHD) yüksek saldırı açılarında zamanla-hızlı-değişen uçuş kararlılığı sınırlarının belirlenebilmesi ve uçuş kontrol yazılımlarının geliştirilebilmesi için gereken hava-akışıdinamiği ve uçuş dinamiği koşullarının bağlantılı olarak incelenebilmesi için kanat ve kanatçıkların zamanlahızlı- değişimleri esnasında uçak üzerindeki akımların çözülmesini sağlayan, çağdaş düzeyde bir ulusal sayısal modelleme yeteneği FLOWER Sayısal Modelinin bir ileri-gelişim derlemi olarak geliştirilmiştir.
