Viscous flow solutions over CN-235 cargo aircraft Uygun, M; Tuncer, İsmail Hakkı (American Institute of Aeronautics and Astronautics (AIAA), 2004-07-01)
Quaternion-based nonlinear attitude control of quadrotor formations carrying a slung load Ariyibi, Segun O.; Tekinalp, Ozan (Elsevier BV, 2020-10-01) Control of a pair of quadrotors carrying a slung load is addressed. A hierarchical control algorithm is implemented on the leader quadrotor. The control system features a linear quadratic tracking controller on its outer loop for velocity command tracking and generates the thrust vector commands for the inner loop. The inner loop uses the to-go quaternion calculated from the thrust vector commands to control the attitude. The second quadrotor, designated as the follower quadrotor, has another hierarchical c...
Aerothermodynamic modeling and simulation of gas turbines for transient operating conditions Koçer, Gülru; Uzol, Oğuz; Department of Aerospace Engineering (2008) In this thesis, development of a generic transient aero-thermal gas turbine model is presented. A simulation code, gtSIM is developed based on an algorithm which is composed of a set of differential equations and a set of non-linear algebraic equations representing each gas turbine engine component. These equations are the governing equations which represents the aero-thermodynamic process of the each engine component and they are solved according to a specific solving sequence which is defined in the simul...
Effect of turbulence modeling for the prediction of flow and heat transfer in rotorcraft avionics bay Akin, Altug; Kahveci, Harika Senem (Elsevier BV, 2019-12-01) In this paper, four turbulence models are compared on the basis of the predictions they produce for the flow and heat transfer in the avionics bay area of a rotorcraft. The turbulence models studied are the standard k-s, Renormalization Group (RNG) k-epsilon, realizable k-epsilon, and Shear-Stress Transport (SST) k-omega model. The avionics bay used in the study houses avionics equipment mounted on the floor and on a rack inside the bay to mimic a realistic distribution of equipment in actual rotorcraft. Th...
Active flow control studies over an elliptical profile Erler, Engin; Tuncer, İsmail Hakkı; Department of Aerospace Engineering (2008) Active flow control by a jet over a 12.5% thick elliptic profile is investigated numerically. Unsteady flowfields are calculated with a Navier Stokes solver. The numerical method is first validated without the jet and with the presence of steady-blowing and pulsating jets. Three jet types, namely steady, pulsating and synthetic jets, are next compared with each other and it is shown that the most drag reduction is achieved by a synthetic jet and the most lift enhancement is achieved by a steady jet. The inf...
