BELL UH-1H helikopteri'nin daimi akış alanı analizi

Bu çalışmada 80 knot hızla düz uçuş gerçekleştiren UH-1H helikopterinin daimi akış alanı panel metodu kullanılarak çözülmüştür. Çalışma ile, yüzey ağı panel sayısının helikopter üzerindeki basınç ve Mach sayısı dağılımı ve bunların entegral sonuçlarına, yani aerodinamik kuvvet ve moment katsayılarına olan etkileri incelenmiştir. Panel metotları çok hızlı sayısal hesaplama yapan metotlardır. Dizayn yaparken sonuçların çok hızlı, saatler mertebesinde olması tercih sebebidir. Bu amacı gerçekleştirebilmek için yaklaşık olarak 10000 panelin gerekli hafıza ve zaman koşulunu sağlaması için yeterli olduğuna karar verilmiştir.

In this work, the forward flight of UH-1H helicopter at a velocity of 80 knots is investigated by using a panel method. Effects of the number of surface panels on pressure and Mach number contours as well as their integral results, namely aerodynamic force and moment coefficients are investigated. Panel methods are very fast tools. During the design process, solutions are needed in the order of couple of hours or even faster. Approximately 10000 panels were determined to be sufficient for satisfying the time and memory requirements.
