Experimental investigation of the helicopter blade tip shape effects on aerodynamic performance and tip vortex characteristics
Uluocak, Sinem; Perçin, Mustafa; Uzol, Oğuz; Department of Aerospace Engineering (2019)
This study experimentally investigates the effects of different rotor blade tip shapes on the rotor aerodynamic performance and the tip vortex characteristics in hovering flight. Force, torque and flow field measurements were performed on a 1.3 m diameter 5-bladed model rotor for four different blades: rectangular (RECT), anhedral (ANHD), tapered-swept (TAPER) and tapered-swept-anhedral (TSA). Thrust and torque measurements show that all tip modifications have a positive effect on the aerodynamic performance wh...

Helikopter pallerinin çoklu kütleli benzetim aracı ve iki boyutlu panel tabanlı akış çözücüsü ile etkileşimli analizi
Soğancı, Semih; Kayran, Altan; Tuncer, İsmail Hakkı (null; 2016-09-30)
Döner kanat hava aracı tasarımında, rotor aerodinamik performansının, titreşim yüklerinin ve pal aeroelastik özelliklerinin hızlı ve etkili olarak hesaplanabilmesi günümüzde geniş kapsamlı döner kanat hava aracı benzetim araçları ile yapılmaktadır. Bu araçlar pal üzerindeki aerodinamik hesaplamaları pal elemanı teorisi kullanarak hesaplamalı akışkanlar dinamiği analizleri ve rüzgar tüneli testleri ile daha önceden hazırlanmış iki boyutlu aerodinamik tablo verilerini ara değerleyerek yapmaktadır. Bu çalışmad...
Development of a comprehensive and modular modelling, analysis and simulation tool for helicopters
Yücekayalı, Arda; Kutay, Ali Türker; Department of Aerospace Engineering (2011)
Helicopter flight dynamic, rotor aerodynamic and dynamic analyses activities have been a great dispute since the first helicopters, at both design and test stages. Predicting rotor aerodynamic and dynamic characteristics, helicopter dynamic behavior and trimmed flight conditions is a huge challenge to engineers as it involves the tradeoff between accuracy, fidelity, complexity and computational cost. Flight dynamic activities such as; predicting trim conditions, helicopter dynamic behavior and simulation of...
Analysis and design of helicopter rotor blades for reduced vibrational level
Tamer, Aykut; Yaman, Yavuz; Department of Aerospace Engineering (2011)
In this thesis analysis and design of helicopter rotor blades were discussed for reduced vibrational level. For this purpose an optimization procedure was developed which involves coupling of the comprehensive rotorcraft analysis tool CAMRAD JA and the gradient based optimization algorithm. The main goal was to achieve favorable blade structural dynamics characteristics that would lead to reduction in vibrational level. For this purpose blade stiffness and mass distributions were considered as the design va...
