Interior noise analysis of a rotary wing aircraft by hybrid statistical energy and finite element analysis
Kanlıoğlu, Recep Hilmi; Çalışkan, Mehmet; Department of Mechanical Engineering (2018)
Prediction of interior noise level within a helicopter fuselage is an important design aspect considering competition in the aviation global market combined with customer's comfort expectations. Especially, in the development phase of a new product, accurate vibro-acoustic models are required to give an engineering assessment to guide the design. The objective of this study is to review noise-generating mechanism on helicopters and vibro-acoustic analysis techniques, and to build two different predictive St...
Development of a rotorcraft time domain system identification software
Aslandoğan, Ongun Hazar; Yavrucuk, İlkay; Gürsoy, Gönenç; Department of Aerospace Engineering (2023-1-03)
A system identification software to identify stability and control derivatives for rotorcraft in hover and forward flight conditions is developed in this thesis. To demonstrate the identification procedure, a high fidelity nonlinear model of the H135 helicopter is used. Frequency sweep, 3211 and 2311 type inputs are given to the nonlinear helicopter model to generate test data. The procedure is carried out by identifying a state space model structure in time domain using output error method with Levenberg-M...
Döner kiriş benzeri havacılık yapılarının yapısal testi için eyleyici yükü hesaplama algoritması ve çok eksenli test ile doğrulanması
Limon, Afif Umur; Ulu, Yusuf; Çöker, Demirkan (null; 2016-09-30)
TUSAŞ bünyesindeki helikopter ana rotor palinin, yapısal dayanım gereksinimleri için kullanılan test sistemine ait hidrolik eyleyici yüklerinin hesaplanması için bir algoritmanın geliştirilmesine gereksinim duyulmaktadır. Bahsi geçen test sistemi, pal üzerine değişken ve sabit genliğe sahip dalgalı merkezcil kuvvet, kiriş bükülmesi, veter bükülmesi ve burulma yüklerini uygulamak amacıyla tasarlanmıştır. Bu çalışmanın amacı, dinamik analiz, statik analiz ve kontrol sistemleri gibi farklı disiplinleri bir ara...
Actuator load calculation tool for a multiaxial test system of a rotating beam like aerostructure
Limon, Afif Umur; Çöker, Demirkan; Department of Aerospace Engineering (2018)
Design and analysis of new helicopter blades need to be verified by testing under combined multiaxial loading including centrifugal force, chord bending, beam bending and torsion loadings. In this thesis, an actuator load calculation tool for a rotating beam like aerospace structure structural test system is developed and is verified by multiaxial testing of a dummy component. The actuator load calculation tool development consists of an analysis and testing part. A dummy structural component is designed an...
Experimental and finite element analysis of rotary draw tube bending process
Dere, Fatih; Darendeliler, Haluk; İder, Kemal; Department of Mechanical Engineering (2014)
Rotary draw bending, which has very good flexibility and easy tooling, is one of the most preferred bending types for tubular profiles. Cross-section distortion and the spring-back phenomena are commonly faced problems in bending processes. Spring-back is the inevitable problem that is to be solved by manufacturer, generally by overbending. For hollow tubes cross-section distortion is another difficulty since using hollow tubes results in higher strain rates and distortions. During the process the thickness...
