The methodology backed by relevant analysis results, flutter flight test (FFT) results, and their interpretation is presented for the flutter qualification of a transport aircraft with wing mounted external store suspension. Before the flight tests, extensive flutter analyses are performed by MSC/Nastran for different weight and CG configurations to reduce the number of costly FFTs based on the results of flutter analysis and decide on the aircraft test configurations. Analysis results and test results indicate that although the flutter speeds of the modified aircraft are lowered compared to the basic aircraft, the overall damping of the wing vibration modes stay above the values required by the flutter regulation MIL-A-8870C.

Aerodynamic modeling and parameter estimation of a quadrotor helicopter Kaya, Derya; Kutay, Ali Türker (2014-01-01) This study focuses on aerodynamic modeling of a quadrotor helicopter and the estimation of the model parameters in wind tunnel tests for hover, vertical climb, and forward flight conditions. The motion of a quadrotor is mainly affected by the aerodynamic forces and moments generated by rotors. Accurate calculation of rotor loads is essential for high fidelity simulation of a quadrotor. Momentum and blade element theories are used to obtain expressions for rotor forces and moments for a traveling vehicle. Th...
Investigation of rotor wake interactions in helicopters using 3d unsteady free vortex wake methodology Yemenici, Öznur; Uzol, Oğuz; Department of Aerospace Engineering (2010) This thesis focuses on developing and examining the capabilities of a new in-house aerodynamic analysis tool, AeroSIM+, and investigating rotor-rotor aerodynamic interactions for two helicopters, one behind the other in forward flight. AeroSIM+ is a 3-D unsteady vortex panel method potential flow solver based on a free vortex wake methodology. Validation of the results with the experimental data is performed using the Caradonna-Tung hovering rotor test case. AeroSIM+ code is improved for forward flight cond...
Adaptive controller applications for rotary wing aircraft models of varying simulation fidelity Tarımcı, Onur; Yavrucuk, İlkay; Department of Aerospace Engineering (2009) This thesis concerns the design, analysis and testing of adaptive controllers for rotary wing aircraft, in particular helicopters. A non-linear helicopter model is developed and validated by trim and dynamic response analyses. A inner-outer loop cascade controller is designed with a trajectory generator in the most outer layer and an adaptive neural network controller is implemented to the inner loop. Controller is then challenged to carry out complex maneuvers autonomously under turbulence. Finally, the ce...
